  • the actuator for the controller is independently driven by -a clock' mechanism.
  • This driving means may .be of any suitable form, such as the usual spring wound clock mechanism with the usual escapement and for present purposes the same should be geared so as to drive the actuated shaft about one revolution during a period of 30 or 40 minutes, which is assumed to be the time necessary for passing through the complete cycle of operations.
  • the clock mechanism is indicated generally by the closed casing 48 from 00 the face of which projects the driven clock mechanism shaft 40a and also below the same projects a shaft 40h which is the shaft for winding the clock' mechanism.
  • the shaft 43 is slidably mounted in the front panel so that it may be pushed inwardly by the user, a compression spring 43h normally tending to hold the shaft 43 outwardly so that, although still having a driving engagement with 5 the shaft 4Ib, it is not normally pushed in the full distance within the hole lic.

  • a compression spring 48e Around the driving shaft 48a of the clock mechanism is a compression spring 48e which forces the clutch element 4I into engagement with the clutch ele- 25 ment v4
  • the clock mechanism is manually wound by the operator by turning the indicator arm 3 in a ccunterclockwise direction which is reverse to the direction of travel of the arm s dunne a operating conditions.
  • a curved arm 41 is fixed to the winding shaft 40h of the clock mechanism and is engaged at its outer end by an arm 48 nxed to the shaft 4Ib. It is evidem from Fig. 1s. that when the arm 4s is 35 turned in a counterclockwlse direction, it will turn the arm 41 and its shaft 48h in a clockwise direction and so wind the spring of the clock sufliciently to operate the same an hour or more.
  • the arm 48 is made in two parts, as indicated 40 in Fig.
  • one part being plvotaliy mounted on the outer end of the inner part so that in case the arm 41 is in the path of the movement of the arm 48, when the latter is turned in a clock- -wise direction, the pivoted end of the 'arm 48 45 will pass over the arm 41.
  • the outer pivoted end of the arm 48 is prevented from rotation on its pivot in the opposite direction and, therefore, is capable of forcing the arm 50 41 in a direction to wind the clock.
  • winding shaft 40h of the clock is driven in a counterclockwlse direction as the clock unwinds, ⁇ and a pin 41a ilxed on the outer casing of the clock limits the movement 55 of the arm 41 in a counterclockwlse direction.
  • Fixed to the insulating disk 44 is a segment 49 which overhangs certain contacts of the controller, as shown in Fig. 15. This segment permits the contact arm 48 to pass freely under it 60 when normally driven and serves as a protector for insuring proper operation of the contact arm 45 when manually moved by the operator.
  • the arm 3 must be pushed inwardly as it cannot be turned against the clock mecha- 70 nism.
  • the pin 46 is moved inwardly and forces the clutch member ⁇ 4I away from the clutch member 4Ia against the pressure of the spring 40e. This releases the clock mechanism from the shaft lib and permits the 75 operator freely to turn the same in a counterclockwise direction for starting the automatic operation, or to turn the shaft in a clockwise direction to hasten the normal operations when desired.
  • the arm can freely pass over the outside of the protective segment 49 but cannot be permitted to engage any of the segments under this shield when released by the operator because the shield will then hold the arm 45 from coming into contact with the contact strips on the insulating disk 44.
  • the operator may move the same past the shield 49 and permit it to engage segments at any other portion of the controller.
  • Fig. 14 shows the parts in their inoperative condition.

  • the engagement with the strip M closes the circuit from the line 25 through the arm 45 to the strip M and thence through the winding of the electromagnetic drain valve Ito the other side of the line. This closes the drain valve.
  • the engagement with the contact strip L closes the circuit across the line through the winding 39 of the gear controlling magnet and forces the portion 31h of the bevel gear into engagement with the segmental gear 35.
  • the engagement with the contact N closes a circuit across the line through the float switch I 8c and the winding of the water supply valve I6 to permit the spraying of the incoming water over the textiles in the receiver 8.

18 Claims.
This invention particularly relates to textile washing machines, and is applicable to dry cleaning and to other special purposes in some features thereof. It may be made of any desired capacity and is especially advantageous in small sized units for use in small apartments where space occupied, quiet operation and pleasing appearance are important qualities. It is also especially advantageous where the washing, rinsing, extracting and drying are to be accomplished in one machine and Without the necessity of any intermediate hand control or of any intermediate handling of the textiles.
One of the main objects is provision of a machine 'of comparatively small size adapted to be enclosed in a cabinet of a simple and pleasing form which may be directly mounted on the iloor or on a low frame. Another object is to give ready accessibility for the insertion and removal of the textiles through a door in the front while leaving the flat top undisturbed and conveniently usable for other purposes. The controls are likewise conveniently mounted and usable at the front of the cabinet. Another important object is to render the machine dependably and safely automatic in the various operations without attention by the user giving eilicient washing, rinsing, extracting and drying in one container. Another object is to permit the user to control, when desired, the length of time of any of the automatic operations by mere setting of the control handle. Another object is the automatic distribution in proper balance of the textiles before the container is accelerated to high speed for centrifugaliy extracting the liquid after rinsing. Another special object is the drying of the textiles to any desired degree by tumbling the textiles so as to be variously exposed in their surfaces to the drying air current, this air curof manufacture, without the necessity of special design thereby giving low cost ofmanufacture. Another object is to relate the parts so that they may be readily and conveniently assembled at low cost and easily inspected and conveniently repaired or replaced'. Another object is to provide durability and dependability with long continued use. Other. objects and advantages will be understood from the following description and accompanying drawings which illustrate preferred embodiments of the invention.

Figure 1 shows the enclosing cabinet of the 35 apparatus which is preferably of well finished sheet metal and is of rectangular form having a iiat top and sides. 'Ihe top and sides are preierably individually removable for access to the enclosed apparatus. The front panel has a door 40 i hinged at the bottom and opening outwardly which is ilrmly heldin closed position by any suitable form of latching device 2 at the top. 'Ihis door may be hinged at the side or top if desired. In the upper right hand corner of the iront panel is a manually rotatable indicator arm 3 adapted to pass over a dial 3a which is graduated to indicate the diilerent sequential operations as the arm 3 moves over itin a clockwise direction. This arm may be manually moved forwardly by the 60 user in case it is desired to hasten any of the operations or omit any of them, the apparatus then continuing to function automatically from the new setting on. In the upper left hand corner of the iront panel is manually rotatable handle Ib for controlling the temperature of the entering water as may be desired by the user through a three-way valve for regulating theintake from the hot or cold water supply.
Referring to Figs. 2, 3 and 4, a fixed container 4 of cylindrical form is positioned so that its axis is horizontal and is fixed at one end to the rear of the front panel' which is formed with rearwardly extending supports 4a and 4b for this purpose. The front end of the container 4 is provided with a large central opening, as indicated in Fig. 4 opposite the door I of the front panel.
n The rear end of the container 4 is closed and has wardly extending arms lc and legs 5d which form supports from the base l of the machine. The container 4, at its lower part, has a downwardly extending formed portion 4c which is inclined downwardly toward the rear of the cabinet and is supported, at its lower portion, by a flange 5e extending forwardly from a web 5f extending between the arms Bc of the supporting bracket. A drain pipe 1 enters the lowest end of the container 4 through the web If, as shown in Figs. 2 and 4.
Within the fixed container 4 is mounted a receiver 8 of cylindrical form and rotatable on a horizontal axis. It has a central circular opening 8a` at the front end opposite the door I of the cabinet. The cylindrical portion is perforated by a series of closely placed small openings lb for permitting the free passage of the liquid from the container 4 to and from the clothes within the receiver l. Mounted within the cylindrical portion of the receiver are axially extending baille plates 8d for purposes of agitation during the washing, rinsing and final drying operations. lThese plates extend inwardly a short distance Within the receiver and are preferably three in number equally spaced apart. 'I'he rear end of the receiver is entirely closed by the end portion thereof and is deflected inwardly, as shown in Fig. 4, and fixed to a rotatable support 8c which is in turn keyed or otherwise fixed to a rotatable shaft l. The support 5 not only forms a support for the stationary container 4 but also forms a bearing and support for `the shaft 9. The reduced end of the shaft 9 extends rearwardly through the bearing 5 and has fixed thereto the driving pulley 9b. This pulley is driven by a belt 9a from the driving electric motor III mounted on the base in the rear left hand corner of the machine, being shown at the right in Fig. 2.
On the base at the right hand side of the machine, as shown in Fig. 3, is mounted another electric motor II. On its rearwardly extending shaft and driven thereby is mounted the rotatable element of a centrifugal blower I2; and on a further rearward extension of the motor driven shaft is mounted the rotatable element of a centrifugal pump I3. On the forwardly extending shaft of the motor I I is mounted a driving element serving to actuate the automatic sequence controlling devices contained within the control box I4.
'I'he water supply. is derived from two pipes I5 and I5a which extend through the rear plate of the cabinet and are connected, one to a hot water house supply pipe and the other to a cold water house supply pipe. 'I'he two pipes Il and Ilia enter a three-way valve I lb of any usual type, from which extends a delivery pipe I5c across the rear of the machine at the top. From the valve I5b forwardly extends control shaft IIid to the front of the machine, as shown in Fig. 4, which is connected at its front end to the water control handle 3b on the front panel of the machine in the upper left hand corner. Thus by turning the handle A3b the incoming supply of hot or cold water,'or both, may be regulated by` means of the three-way valve to give any desired temperature of the water entering the machine. In the water supply pipe lic. which crosses the rear top portion of the machineHis inserted an automatically controlled intake water valve I8, as shown in Fig. 2. This valve is normally closed by spring pressure or gravity and automatically opened by exciting the coil of a solenoid magnet contained within the top portion IIia of the valve. 'I'his valve structure may be of any form which normally seeks the closed position and is opened only when its controlling coil is energized. The intake water supply pipe, after passing through the valve I8, extends forwardly and downwardly and is connected at its front end to a hollow ring casting I1 which is formed on the rear of the front panel, as shown in Fig. 4, and is shown more in detail in Fig. 5. This ring casting I1 is concentric with the horizontal axis of the machine and forms a circular entrance to the receiver 8 when the door is opened. The ring I1 is hollow, as shown in Fig. 4, and, as shown in Fig. 5, the hollow opening is partitioned into an upper and lower part by partitions` I 1a and I1b which are somewhat displaced from the horizontal for convenience Yof connection to the supply piping. 'I'he lower divided portion of the ring serves as the intake and distributor of the water or other cleaning liquid and is perforated at its lower central portion by a series of openings I1c which serve to deliver and spray the water through the opening 8a of the receiver on to the clothes within it. These perforations I1c are likewise shown in Fig. 4. Thus, when the water supply is on, the clothes are quite uniformly sprayed during the initial wetting for Washing and also during the rinsing process. 'I'he ring I1 has an inclined outer surface, as shown in Fig. 4, and the inner side of the door I carries an inwardly extending circular flange Ia which carries a circular gasket Ib which, when the door is closed, engages the inclined front face of the ring I1 and serves to form a seal against leakage of the liquid. 'I'his gasket may be of rubber or any suitable yieldable material.
The air supply for drying the clothes is taken from a continuously operating air pump I2, as shown in Fig. 3, coming from an entrance pipe I 2a through an opening in the right hand side cover plate near the base of the machine and, after passing through the pump, is forced through an outlet pipe I2b, which extends across the lower portion of the machine and upwardly at the front portion and then into the upper partitioned'half of the ring I1, as shown in Fig. 5. The air flow passes through this hollow ring and then out through an elongated opening I 2c located at the lower part of the top portion of the ring I1 so as to deliver air downwardly toward the central opening 8a of the receiver, as shown in Fig. 4. An outlet for the air current is provided by a hole I2d at the right hand upper side portion of the container 4, as shown in Fig. 3, from which hole the pipe |2e leads upwardly and out through a hole at the top of the right hand side plate of the cabinet.
'I'he drain pipe 1 from the container 4 passes through an automatically controlled valve 1a, asshown in Fig. 2. This valve is spring pressed to normally assume anopen position and. is automatically closed by a solenoid magnet contained within the topportion 1b of the valve. This electromagnetic valve may be of any form which is adapted to close when energized and to open when de-energized. The drain pipe 1 continues from this valve and is connected to the intake of the,- continuously operated pump |3. The outlet i3d-,of the pump, as shown in Figs. 2 and 3, passes out through an opening in the side plate of the cabinet at the lower right hand corner and is connected to the waste drain of the household.
Mounted on one of the arms 5c of the supporting bracket, is a float switch I8, as shown in Figs. 2 and 3, in the form of a closed box from f the bottom of which extends a pipe Ila which connects through an opening in the lower portion of the container 4 with the interior thereof. This -is so located that when the water level reaches a predetermined height, the float lib will rise and force upwardly a switch contact |8c and thereby interrupt-the circuit of the eletromagnetic valve I6 and permit the closing thereof. Thus the supply of washing liquid can never rise above this predetermined level, even though the control circuit of thisvalve be controlled tending to open the valve at another control contact of the circuit.
The sequence control mechanism. contained within the control box |4 is, as shown in Fig. 6, driven by the shaft ||a of the control motor Within the box on the end of the shaft ||a is a worm I9 driving a worm wheel Isa, the shaft of which carries a worm |9b which in turn drives a worm wheel |9c having a shaft extending at right angles to the shaft of the wheel Ha. It will be understood that the shafts of this driving mechanism are suitably supported in bearings in a manner understood by those skilled in the art, these bearing supports being omitted from Fig. 6 for the sake of clearness. The shaft of the wheel Isc in turn carries a worm |9d which drives a worm wheel |9e as well as an upper worm wheel Isf, these driving wheels having parallel shafts at right angles to the shaft of the worm wheel |9d. The shaft of the wheel Ise carries a fixed eccentric or cam Ita which is adapted to intermittently engage and depress a pin |9h. This pin is fixed at its lower end to a flexible element |81 which carries a contact |91 at its outer end and is fixedly supported at its other end to support |9k. When the pin is not engaged by the cam |90, the contact Hi makes engagement with an upper fixed contact |91 and when the pin |9h is depressed by the cam, it is caused to engage a fixed contact Ism mounted on the base of the control box. It will, of course, be understood that these engaging contacts are electrically insulated from the rest of the apparatus and that the element isi is mounted upon an insulating support and that the pin |9h is likewise insulated from the ilexible element |91. Thus by this gear reduction, the eccentric |80 makes one revolution for a very large number of revolutions of the motor shaft lla; any suitable form of speed reduction mechanism may be used and the reduction proportioned to give the desired ratio of revolutions of the driving shaft to that of the eccentric shaft.
On the opposite'side of the control box |4 from the shaft 'I la is mounted another shaft 2l 'shown in alignment with the shaft v| la. The shaft 2l extends outwardly and carries at its outer end a bevel gear 20a, as shown in Fig. 3, which in turn meshes with another bevel gear 20h fixed on the lower end of an' upwardly extending vertical shaft 20c. This is suitably supported in bearings mounted on the inside of the front panel and carries at its upper end another bevel gear 20d which in turn meshes with a bevel gear 20e on the inner end of a shaft passing through the front panel in the upper right hand corner thereof. On the outer end of this shaft is fixed the indicator arm I which indicates, by its movement with reference to the dial 3a. the successive stages of operation and the particular function being performed by the apparatus at any phase of lthe operating movement. The indicator 3 is controlled to make nearly one complete revolution during the entire series of operations.
Returning to Fig. 6, the shaft 20 extends inwardly through the control box and is connected by a one way acting clutch to another shaft 2|. A suitable form of clutch is shown in Fig. 7, wherein balls or rollers 22 are located in cut-away portions on the outside of the shaft 2| and enclosed byl a sleeve 20j' which is fixed to shaft 20. When the shaft 2| is turned in one direction, that is clockwise, in looking at Fig. 7, shaft 20 evident that when shaft 20 and its sleeve 20j Y is turned independently of movement of the shaft 2| in a clockwise direction, the shaft 2| will not be moved thereby. Thus the shaft 20 may be advanced by the turning o f the indicator arm 3 to any position desired on the index dial without turning the shaft 2 The shaft 2| has fixed to its inner end a worm gear 2lb which is driven by a worm 2|c on the shaft which carries the worm wheel Isf and which, as above pointed out, is driven by the worm Illd. Thus, in normal operation. the shaft 2| is driven by the motor shaft ||a at a great reduction in speed, this reduction being such that the shaft 2| is turned nearly one complete revolution during the complete sequence of the op- 1 erations of the machine.
The various operations are electrically controlled by means of a sequence controller driven by the shaft 20. This consists of a stationary insulating disc 23 mounted on the wall of the con trol box |4 and concentric with the shaft 2|l.
The insulating block 2l carries a series of concentric contacts 23a, as shown in Fig. 8. Fixed to the shaft 20, but insulated therefrom, is a contact arm 24 which carries a series of contacts adapted to engage respectively with the contacts 23a. The contacts carried by the arm 24 should be individually springpressed against the contacts 23a so as to insure proper engagement therewith as the arm 24 passes over them and any proper mounting of the movable contacts that will insure connection of them with the contact arm 24 and proper engagement with contacts 23a when the arm passes over them, may be utilized, as will be understood by those skilled in the art. Likewise, instead of making the controller in the form of a disc controller, it may be made in the form of a drum controller having the contacts 23a carried by a drum mounted on the shaft 20 and rotatable therewith while the engaging contacts of arm 24 are fixed in posi- Cil tion, as will be understood by those skilled in the art.
Referring to Fig. 8, the electrical connections of the various parts already described are shown in their relations to the electric controller. The main driving motor i is shown in the lower right hand corner of the diagram and is indicated as a series type, or universal motor having an armature with commutator connected in series with one or the other of the reversible iield windings Illa and Ib, although any form of reversible motor may be used and controlled to reverse its direction of rotation. The control motor II, which drives the air pump I2 and water pump I3, as well as driving -the controller arm 24, is likewise shown as a series motor, although any suitable form of motor may be used which will give approximately constant speed, operating continuously in one direction. The supply lines 25, 25' are shown at the left of the diagram and pass through a main switch, such as a plug and receptacle, for connecting the supply lines to the apparatus. The reversing switch |91' is shown in the lower left hand corner of the diagram and is biased to have its contact |97' normally engage the upper iixed contact ISI. The eccentric ISU operates to intermittently depress the switch I9i to engage the fixed contact Ism for reversing the direction of rotation of the main driving motor I0, as will hereafter be explained. The float valve I8 controlling the switch I8c is shown connected in series with the winding of the electromagnet IGa controlling the water supply valve I6. The winding of the electromagnet 'Ib controlling the drain valve 'la is shown connected in series between the supply line 25' and one of the fixed contacts of the controller. A ballast or load resistance 26 is shown connected in series with the switch |91' and in turn is connected to contacts of the controller 23a. It serves to limit the maximum current to a predetermined amount when the motor I0 is reversed. A resistance 21 is connected in series with one of the field windings Illa and with the armature of the motor I0 when the contact arm engages a contact of the controller to which the resistance 21 is connected. This resistance serves as a starting resistance for the main motor when it is to be operated in one direction at high speed and serves to gradually start the motor. When this resistance is cut out of the motor circuit by the controller arm, the motor is brought to high speed. A heating resistance 28 is connected in series between the supply line 25' and one ofthe contacts of the controller, this resistance being for the purpose of heating the air during the drying operation of the machine and being located in the path of the air as it emerges from the opening I2c as forced by the air pump, as indicated in Fig. 5.
In describing the operation, it may be first assumed that the contact arm 24 of the sequence switch or controller is inthe oiI position, making no contact with the iixed segments of the controller, as indicated in Fig. 8. The indicator arm 3 is then in the vertical position shown in Fig. 1. The door of the front panel is opened and the textiles to be washed are inserted through the opening 8a and placed in the receiver 8, A proper amount of powdered or flaked soap or similar washing material, is thrown over the dry textiles after their insertion. The door I of the front panel is then closed. 'I'he operator then turns the indicator arm 3 to the right for initiating the operation of the apparatus which then continues to pass through the different operations in se-` quence, as automatically carried out by the control devices. The turning of the dial indicator 3 slightly to the right causes. through Athe bevel gears and shaft c, the turning of the shaft 2U. This results in the contact arm 24 being moved manually in a clockwise direction to make contact with the strip A of the controller. The contact arm 24 is electrically connected to the supply line 25 and the engagement with contact A closes a circuit to start the control motor II as follows: from the arm 24 to contact A and thence to the motor Il and then to the supply line 25'. This starts the control motor which operates continuously during the entire cycle of movements because the contact strip A is continuous and is the last contact broken when the arm 24 passes off this contact strip, as evident from the controller diagram. As soon as the motor Il starts, it serves, through the reduction gear already described, to drive the shaft 2 I and thereby slowly tofmove the contact arm 24 over the flxed contacts of the controller. The control motor Il also serves, during its operation, to drive the drain pump I3 and the air pump I2, insuring the quick emptying of the container 4 at any time the drain valve 'la is open and also serving to pass a continuous flow of air through the receiver, as already described, which becomes effectively utilized in the drying operation. The travel of the contact arm 24 brings the same into engagement with the contact strip B. This closes a circuit through the main driving motor I0 and starts the same in one direction by means of a circuit from the contact arm 24 through the contact strip B, thence through the load resistance 26 to switch I9i to the upper contact I 91 and then through the field winding lua and armature I0 of the motor to the other side of the line. In the meantime, the eccentric ISg of the control box is driven by the motor Il through the reduction gearing, already described, so that it continuously operates iirst to force the switch I9 against the contact Ism and then to permit the switch to engage the contact |91 and then to cause it to engage the contact Ism alternately to cause the reversal of the motor I0, as is evident by tracing the circuits. Thus, when the contact, ISm is engaged, the current passes from the arm 24 through contact B, load resistance 26, switch |91', contact ISm and thencethrough the field winding Illb and motor armature to the other side of the line. This reverses the iield of the motor 4and causes its rotation in an opposite direction from that occurring when the eld winding Illa is energized. 'Ihe reversal of the motor I0 serves, through the driving belt 9a and pulley 9, to reverse the direction of rotation of the receiver 8 for the washing operation. The time of rotation of the eccentric lag may be made any interval desired but it is preferably geared so that the receiver 8 is turned about one revolution or somewhat more in each direction before reversal.
In addition to engaging the contact B, the arm 24 likewise engages the contact C. I'his closes a circuit from the line 25 through the arm 24, contact C and winding of the magnet of lb to the other side of the line. This automatically closes the drain valve 1a. Contact is also made by the arm 24 with the strip D of the controller which closes a circuit from one side of the line, through the oat switch lic and then through the winding of the magnet lia to the other side of the line. 'I'his automatically opens the water supply pipe and permits the entrance of the ywashing liquid through the spray holes I1c, the operator having adjusted the handle Ib on the front panel of the cabinet to give a desired temperature of the entering water from the hot or cold water supply by means of the three-way valve lib. The water continues to rise in the container 4 to a predetermined level at which time the float valve opens the switch llc and breaks the circuit of the electromagnet of supply valve I6 and permits the same to assume its closed position.
The washing action continues under these conditions for a predetermined time while'the arm 24 is slowly travelling over, and in contact with, the four contact strips A, B, C and D. After the washing action has continued a suflicient time to thoroughly wash the textiles,` the arm passes off the contact strip C which de-energizes the drain valve and permits it to open and, through the action of the pump Il, the used liquid is rapidly drained from the container 4. The draining of the liquid causes the float valve llc to close which energizes the circuit of the electromagnet of supply valve I8 and results in a supply of fresh water being sprayed within the receiver through the perforations I1c. In the meantime, while the arm 24 is continuing to travel over the contacts A, B and D, the receiver 8 is being continuously reclprocated and tumbling the textiles therein by the action of the bales 8d and the continued reversing action. Thus, during this rinsing process,` a continuous supply of fresh rinsing water is sprayed upon the textiles while they are variously tumbled and the container 4 is kept empty by the continued action of the pump I2, Thus a thorough and eifective rinsing of the textiles takes place.
The rinsing period occurs while the contact arm 24 is travelling from the end of the contact strip C to the ends of the contact strips B and D.
When the arm 24 passes off the contacts B and D, the circuit of the main motor III is interrupted and it temporarily ceases to operate and the circuit of the electromagnetic inlet valve is likewise opened permitting this valve to close. The next operation is to extract the surplus water from the textiles by rotating the receiver 8 at high speed in one direction. In accomplishing this result it is vitally important that the textiles be quite evenly distributed circumferentially around the inside of the receiver 8 so that the load producing strain on the receiver 8 is properly balanced. Otherwise the unbalancing will cause a great side strain on the machine. especially at the high speeds, resulting in a pounding and racking effect which might lead to serious damage. It is, therefore, important in the automatic control of the receiver 8 to attain the automatic even distribution of the textiles within the receiver before high speed operation is arrived at. This is accomplished by bringing the speed of the receiver gradually up to high speed. During this gradual increase in speed the 'textiles whichare initially at the bottom of the receiver 8 are gradually carried around and tumbled by the baflles 8d until, as the speed increases, the textiles are gradually and evenly distributed around the interior of the receiver 8 so that, when passing to high speed, no unbalanclng exists and the machine operates smoothly at the highest speed for centrifugally extracting the water.
Thus, referring to Fig. 8, the arm 24, after the completion of the washing and rinsing process, next engages the contact E. This closes the circuit of the main motor II! from the supply line 28 through arm 24, contact E, resistance 21, field winding Ila and armature I0 to the line 25'. The resistance 21 may be adjusted to give the desired rate of acceleration in speed and, after this has once been determined, the resistance may be nxed. The motor I0 being now operated in one direction continuously and under a much less load than during the washing operation, gradually increases in speed while the arm 24 is passing over the contact E. It then engages the contact F which results in shortcircuiting the resistance 21 in the circuit of the motor and permits the motor and receiver 8 to pass to high speed operation for extracting the water. When the arm 24 engages the contact F, it likewise engages the contact G which is electrically connected to contact D and serves to energize the inlet valve for the purpose of a short interval of final rinsing with fresh water. The arm 24 then passes oil. the contact G while continuing engagement with the contact F for operating the main motor and receiver 8 at high speed for extracting the maximum amount of water centrifugally. Thiscompletes the extracting operation.
. The contact arm next passes off the contact F for stopping the motor, and after a sumcient time interval permitting the receiver to come to rest, it then engages the contact H to again start the motor. 'Ihis closes the circuit of the main motor I8 through'the load resistance 28 and reversing switch |91 and thus causes the motor III and receiver 8 to start and resume the reverse action, the same as took place during the washing operation as previously described. The damp clothes are now tumbled in the receiver 8 by this reverse operation and the continuous air flow through the receiver, as forced by the v air pump I2, gives an effective and quick drying operation. The drying is hastened by the electric heater 28 which becomes energized by the arm 24 engaging the contact strip K by a circuit from the arm 24 through contact strip K, heating resistance 28 and thence to the other side of the supply line. The heated air flow soon completes the dryingof the clothes during the passage of the arm 24 over the contact strips H and K, after which the main motor and heating resistance circuits are broken by the arm 24 passing of! these contact strips. Soon afterward the arm 24 passes off the contact stripl A and the circuit of motor II is interrupted and the cycle of operations is then completed.
The user then opens the door I of the front panel and removes the dry textiles. Thus the soiled textiles or fabrics are introduced into the machine dry, are subjected to a thorough washing, rinsing, extracting and drying operation in sequence and at the completion of the cycle, the textiles vare removed from the machine clean and dry.
If, at any time the user desires to hasten any one of the sequential operations, or to pass over them quickly, the operator may turn the indicator arm 3 in a clockwise directionr to any part of the dial and then let the machine continue the automatic'operation from that point on or until again hastened by the user. In this manual turning of the indicator arm 3, the shaft 2li is turned, as already explained, together with the contact arm 24, the one way clutch, already described, permittingthis manual forward adjustment. After such adjustment the control motor II takes up the continued movement of the arm 24 as already described.
It is thus apparent that by this improvement, the machine serves to effectively carry out the washing, rinsing, distributing, extracting and drying operations all within a single container and receiver in an automatically controlled series of operations without the use of any auxiliary compartments, tanks or supplementary apparatus. It is conveniently accessible through the front panel door on the front side of the machine for introduction and withdrawal of the fabrics and avoids the necessity of any intermediate handling, splashing or dripping of water or of the washing liquid. It likewise, by its simplicity and utilization of one container and receiver for all purposes, permits `the unit to be made of a comparatively small size adapted for use in small apartments while being of ample capacity. 'I'he unit is obviously capable of being made in different sizes for fullling the requirements of the larger households.
It is evident that the duration of the different periods of the cycle may be changed by lengthening or shortening the contact strips of the electric controller and, if desired, one or more of the sequential operations may be omitted without departing from the scope of the invention, and various changes may obviously be made in the structure and relationship of the various parts of the apparatus.
In case it be desired to soak the fabrics in the machine =before washing, the apparatus could be started in the usual way and then stopped at the initiation of the washing period, as by pulling vout the plug connection to the house wiring, or otherwise opening the main circuit. In such a case if the house drain is above the drain outlet of the machine, the stopping'of the drain pump would avoid emptying the container; and if the house drain is below the drain outlet of the machine, a shut oil' valve in the drain connection could be manually closed. The soaking could also be accomplished without starting the machine by providing a by-pass having a manual valve, around the automatic valve I6 for filling with washing liquid. Likewise, in case only a comparatively short period of soaking were desired, the controller 23a could be modified by delaying the starting of the motor I0 for permitting a soaking period while the arm 24 slowly traverses the strips A, C and D for some distance before engaging the strip B. This could obviously be accomplished by extending the strips A, C and D some distance in a counterclockwise direction, with reference to Fig. 8, beyond the lower end of strip B which controls the motor i0. y
Also although an air .blower I2 has been described for maintaining a circulation of air through the. receiver 8 for drying the fabrics, this air blower may be -omitted in some instances.
container for drying may be obtained. The,
bailies Id serve to assist the airflowand special fan blades could be. attached to the receiver lf- I I desired.
Althoughl in the above described machine the receiver I is `driven valternately in opposite di- A sufficient passageA of air through the receiver 3 for drying may be obtained by the re-v ceiver l itself acting as a blower because it acts rections during the washing and drying periods,
the control could readily be modified to drive the receiver 8 in one direction only at a comparatively slow speed during either one or both oi these periods and still obtain satisfactory washing and drying operations. In that case the reversing switch I9i would be unnecessary and the circuit of motor i0 would then pass from contact strips B or H. or both strips, through a suitable resistance such as 26 for maintaining a low speed and then through the motor to the other side of the line, as shown in Figs. 17 and 18. In such a slow speed movement of the receiver 8 in one direction only, the fabrics are carried along by the baiiles and then fall or tumble as they approach or arrive at the inside top of the receiver, during either the washing or drying period or both, as desired.
In the remaining figures of the drawings another embodiment of the invention is shown wherein only one electric motor is used which operates continuously in onedirection and wherein the time control of the different operations is dependent upon aclock mechanism as another embodiment of the invention, instead of using a control motor with a reduction gear, for this purpose. Likewise, in this further embodiment of thoe invention, instead of reversing the main motor, a reversing gear is utilized for obtaining the reverse action during the washing operation and during the drying operation.
Thus referring to Figs. 9, 10 and 14, the parts having the same reference characters as already referred to, are similar to those already described. The single driving electric motor 30 is mounted on the base at the rear of the machine and has its axis parallel with the front panel of the cabinet. The shaft of this motor drives the main pump I3 mounted at one side of the motor and the air pump i2 mounted at the other side of the motor. The bottom of the container 4 is converged towards the middle, as indicated in Fig. 9, and the drain connection is connected thereto at its lowest point and passes through the electromagnetically controlled drain valve la, normally open, and thence to the pump I3 which delivers to the waste system of the household. The air pump i2 has its inlet through a hole in the rear of the cabinet and an outlet, which is connected by the pipe IZb, preferably of copper and bendable, to the upper half section of the ring I1, the same as described in the former apparatus. The water supply is likewise the same as already described, the supply pipe IBc having located therein the electromagnetically controlled valve I6, normally closed, and the outlet end of the pipe |-5c`is connected to the lower part of the casting I -1 as previously described. As thus far described, the structure is generally similar to that disclosed by Figs. 1 to 8 and similar corresponding parts need not be again. particularly described.
The gear drive for controlling the rotation of the receiver 8 is, as shown in Figs. '9 and 10, enclosed within a box 3| mounted at theA rear of the machine and is supported bythe bracket which likewise serves las the bearing support for the shaft driving the receiver 8 and which also serves to support the rear end of the container '4. The horizontal shaft 32 has an end projectaston theshaft or the motor 3o.
Referring to Figs. 11 to 13, the shaft 32 is shown mounted in bearings depending from the top of the gear case and has i'ixed to it a worm 32a. This worm continuously drives' in one direction the worm wheel 34 supported by a stub i shaft mounted from the inner front side of the gear case. Pivotally supported. on a stub shaft at the bottom of the gear case extending'from- 82 is fixed a bevel gear 32h. The shaft l which drives the rotatable receiver 8 of the machine is, as shown in Fig. 13, provided with an extension l 9c which enters the gear box and is supported in opposite sides thereof. 'I'he axis of this shaft is in the horizontal plane of the axis of the driving shaft 32 and carries a double bevel gear 31a and 81h. This double bevel gear is slldably keyed to the shaft 8c and may be moved to cause the bevel portion 31a to engage the bevel gear 32h. or may be moved to cause the bevel gear portion 81h to engage the segmental bevel gear 35. The double bevel gear has a central circular slot 31c. This slot is engaged by the forks of a shifting element 38 which is pivotally mounted above the gear in an upwardly extending portion of the top of the gear case, as shown in Fig. 12. 0n the top of the gear case is mounted a solenoid magnet having a winding 33 and a plunger 38a. the axis of which is horizontal. The outer end of the plunger is above the shifter 38, the latter being plvotally connected thereto by a pin and slot connection. A tension spring 39h is secured 40 at one end of the enclosing box 3lc of the magnet and at its other end to the end of the plunger 38a. The spring thus tends to move the plunger and shifter 38 so that normally the bevel gear portion 31a is in engagement with the gear 32h.
In this modification of the invention instead of using an electric motor driven electric controller as in the embodiment first described, the actuator for the controller is independently driven by -a clock' mechanism. This driving means may .be of any suitable form, such as the usual spring wound clock mechanism with the usual escapement and for present purposes the same should be geared so as to drive the actuated shaft about one revolution during a period of 30 or 40 minutes, which is assumed to be the time necessary for passing through the complete cycle of operations. In Figs. 15 and 16 the clock mechanism is indicated generally by the closed casing 48 from 00 the face of which projects the driven clock mechanism shaft 40a and also below the same projects a shaft 40h which is the shaft for winding the clock' mechanism. Slidably mounted on the outer end of the shaft 40a and driven thereby is one element 4l of a disk clutch. The other element 4ia o f this clutch is secured to a shaft 4ib mounted in the enclosing casing 42. The outer end of the shaft 4Ib is enlarged outside of the casing and has a square central hole 4ic in its outer end. The control indicator arm 3 mounted in the upper right hand corner in the front panel of the cabinet, -as shown in Fig. 1, is in the present case secured to a shaft 43 which passes through the panel. The inner end 43a of this shaft is squared to slidably engage the hole 4Ic. The shaft 43 is slidably mounted in the front panel so that it may be pushed inwardly by the user, a compression spring 43h normally tending to hold the shaft 43 outwardly so that, although still having a driving engagement with 5 the shaft 4Ib, it is not normally pushed in the full distance within the hole lic. Mounted upon the inside face of the front panel in a fixed position is an insulating disk 44, the inner face of which carries the concentric contact strips 10 of the controller. 'Ihe shaft 43 is freely movable through the center of this longitudinally. 'Ihe shaft 43 drives thev insulated contact arm 45 which engages through yieldable movable contacts, the contact strips on the face of the disk 44. 15
A pin 43 'is freely movable longitudinally through a central hole in the shaft 4Ib and likewise freely movable through the clutch element 4|a and engages, at its inner end the center of the clutch element 4I. The other end of the 2 pin is extended to engage the inner end of the squared portion of the shaft 4ia. Around the driving shaft 48a of the clock mechanismis a compression spring 48e which forces the clutch element 4I into engagement with the clutch ele- 25 ment v4|a under normal operating conditions.
The clock mechanism is manually wound by the operator by turning the indicator arm 3 in a ccunterclockwise direction which is reverse to the direction of travel of the arm s dunne a operating conditions. For this purpose a curved arm 41 is fixed to the winding shaft 40h of the clock mechanism and is engaged at its outer end by an arm 48 nxed to the shaft 4Ib. It is evidem from Fig. 1s. that when the arm 4s is 35 turned in a counterclockwlse direction, it will turn the arm 41 and its shaft 48h in a clockwise direction and so wind the spring of the clock sufliciently to operate the same an hour or more. The arm 48 is made in two parts, as indicated 40 in Fig. 16, one part being plvotaliy mounted on the outer end of the inner part so that in case the arm 41 is in the path of the movement of the arm 48, when the latter is turned in a clock- -wise direction, the pivoted end of the 'arm 48 45 will pass over the arm 41. When the arm 48 is moved in a counterclockwlse direction, the outer pivoted end of the arm 48 is prevented from rotation on its pivot in the opposite direction and, therefore, is capable of forcing the arm 50 41 in a direction to wind the clock. It will be understood that the winding shaft 40h of the clock is driven in a counterclockwlse direction as the clock unwinds, `and a pin 41a ilxed on the outer casing of the clock limits the movement 55 of the arm 41 in a counterclockwlse direction. Fixed to the insulating disk 44 is a segment 49 which overhangs certain contacts of the controller, as shown in Fig. 15. This segment permits the contact arm 48 to pass freely under it 60 when normally driven and serves as a protector for insuring proper operation of the contact arm 45 when manually moved by the operator. Thus whenever the operator wishes to turn the dial indicator arm 3 manually, to reverse the same 65 for winding the clock mechanism, or to advance the same during normal operation of the machine, in order to selectively hasten some of the operations, the arm 3 must be pushed inwardly as it cannot be turned against the clock mecha- 70 nism. When thus pushed in, the pin 46 is moved inwardly and forces the clutch member `4I away from the clutch member 4Ia against the pressure of the spring 40e. This releases the clock mechanism from the shaft lib and permits the 75 operator freely to turn the same in a counterclockwise direction for starting the automatic operation, or to turn the shaft in a clockwise direction to hasten the normal operations when desired. During this movement the arm can freely pass over the outside of the protective segment 49 but cannot be permitted to engage any of the segments under this shield when released by the operator because the shield will then hold the arm 45 from coming into contact with the contact strips on the insulating disk 44. By further turning the arm 3 and contact arm 45, the operator may move the same past the shield 49 and permit it to engage segments at any other portion of the controller.
The control of the various parts of this form of the invention and -the automatic action thereof will be understood by reference to Fig. 14 wherein parts already described are similarly designated. Fig. 14 shows the parts in their inoperative condition. The arm 45 is then in engagement with a pin 45a where it has been forced by the clock in completion of the sequential operations of fthe machine. After the operator has inserted the textiles within the receiver 8 and sprinkled the same with the washing substance, such as powdered or fiaked soap, the dial arm 3 will be pushed inwardly and turned counterclockw'ise which will push the pin 46 inwardly and unlatch the clutch from the clock mechani-sm and cause the winding of fthe clock and bring the arm 45 to engage the other side of the pin 45a. 'I'he arm 3 is then released and the closing of the clutch will permit the clock to start driving the contact arm 45 in a clockwise direction. The contact strips of the fixed portion of the controller are represented in Fig. 14 and also in Fig. 8 as viewed from the front of the machine for simplicity of understanding. As the arm 45 moves from the pin 45a in a clockwise direction, it first engages the three inner concentric contact strips L, M and N. The engagement with the strip M closes the circuit from the line 25 through the arm 45 to the strip M and thence through the winding of the electromagnetic drain valve Ito the other side of the line. This closes the drain valve. The engagement with the contact strip L closes the circuit across the line through the winding 39 of the gear controlling magnet and forces the portion 31h of the bevel gear into engagement with the segmental gear 35. The engagement with the contact N closes a circuit across the line through the float switch I 8c and the winding of the water supply valve I6 to permit the spraying of the incoming water over the textiles in the receiver 8. The opening of this circuit by the float switch, at a predetermined level of the washing liquid, will permit the automatic closure of the water supply valve. The engagement of the contact arm 45 with the outer contact strip O closes a circuit from one side of the line through the strip O to the field winding and amature of the motor 3U and to the other side of the line. This starts the electric driving motor 30 which drives the shaft 32 of the gear box and by means of the worm and wheel drive and link 36 causes a reciprocating movement of the segmental gear 35. The gear ratio is such that the receiver 8 will be alternately driven in opposite directions through the segmental gear 35 about one revolution or somewhat more in each direction. This reversing washing action continues while the contact arm 45 continues to travel in a. clockwise direction over the contact strips L, M, N
and O. After a suitable washing period, the arm 4l passes of! the strip M, at which time the circuit of the winding of the drain valve 'la is broken, permitting the same to open and allowlng the -drain pump to force the waste water out of the machine.
The lowering of the liquid level in the container 4 soon permits the closure of the float switch I8c which causes the energizwtion of the winding of the inlet valve to admit a supply of fresh water. Thus, while the receiver l is continuing to be reversed by the driving gear and tumbling the textiles, the water is sprayed within the receiver to give an effective rinsing of the textiles while the contact arm continues to pass over the contact strips L, N and O. It then passes off the strip O which breaks the circuit of the motor 30 and stops the driving of the rel ceiver 8. The arm next passes off the contact strip N and breaks the circuit of the winding of the inlet valve permitting it to close; and it likewise passes off the strip L and breaks the circuit of the winding 39, permitting the spring 39h to draw the plunger 39a to its initial position and thereby shift the bevel gear portion 31a into engagement with the bevel gear B2b. This completes the rinsing operation. 'I'he controller is now in a position to initiate the extraction of the water from the textiles by high speed centrifugal action and in passing to this operation, the receiver 8 must be gradually increased in speed so as to permit the even distribution of the textiles within the receiver 8 to give a proper balancing thereof before passing into the high speed operation of the receiver in one direction of rotation.
For this extracting operation, the arm first engages contact strip P which closes the motor circuit from one side of the line through the resistance and thence through the motor to the other side of the line. 'I'his resistance serves to start the motor at slow speed and to give a comparatively slow rotation of the receiver 8 in one direction, the bevel gears 31a and '32h being now in engagement for this purpose. The continued movement of the contact arm 5 causes it to next engage the contact Q which results in somewhat increasing the speed of the motor by cutting out a portion of the starting resistance 50. Further movement of the contact -arm results in cutting out another section of this resistance by engagement with the contact strip R. In next engaging the contact strip S, all of the resistance 50 is removed from the circuit of the motor which results inthe receiver 8 being driven at a high speed for centrifugally forcing the water from the textiles. This high speed action continues while the contact arm 45 traverses the strip S. During the gradual increase in speed of the receiver 8 and before attaining high speed, the textiles will be evenly distributed around the inside of the receiver l as the starting resistance is gradually cut out, thus preventing the possible damaging results -and objectionable operation which would accompany high speed operation if the load were unbalanced. Although the resistance 50 is divided into 3 sections, this number may be made more or less depending upon the maximum speed of the machine and other factors of design.v Thus, in Fig. 8, only one step of a starting resistance is utilized.
In Fig. 14 the dotted lines enclosing the contact strips Q, R and S indicate the shield 49 previously described in connection with Fig. 15-
-This shield, as already explained, permits the contact arm 45 to pass under the same during the normal sequential operation of the apparatus, but when the operator attempts to turn the indicator arm 3, after pushing it inwardly, the shield will not permit the operator to cause the manual engagement of the contact arm 45 with the strips Q, R and S because the arm 45 must be turned beyond the two limits of the shield 49, in one direction or the other, before the contact arm 45 is permitted to engage any of the contact strips. If the operator wishes to hasten or pass over any of the operations of the machine otherwise automatically controlled, the indicator arm 3 may be pushed inwardly and advanced during the normal operation of the machine, to any position .and from there continued, but the shield 49 requires the automatic control and proper inclusion of the sections of the resistance 50 in the motor circuit during the gradual increase in speed and equalization of the load when passing to the high' speed extracting operation.
After completion of the extraction process, by the contact arm passing off the strip S for stopping the motor 30, and after'permitting a sumcient time interval for the receiver 8 to come to rest, the contact arm 45 next engages the contact strip T. This excites the solenoid magnet winding 89 which shifts the double bevel gear so that the portion 31h is moved into engagement with the segmental gear 35. The contact strip U is next engaged by the contact arm which closes the circuit of the electric motor which thereby causes the driving of the receiver 8 in a forward and backward rotation alternately, as already explained with reference to the washing action. The circuit of the heating resistance 28 is also closed at this time by the contact arm engaging the strip V. Thus during the tumbling of the textiles by the forward and backward motion of the receiver 8, the air flow through the receiver, as forced by the pump I2, is caused to pass around the heating resistance 28 giving a warm ow of air through the receiver. Thus the textiles are dried while the contact arm 45 slowly travels over the length of the strips T, U and V. The cycle of operations is completed by the contact arm 45 passing from the ends of the strips U and V, which stops the motor and breaks the circuit through the heating resistance and then passing of! the strip T, which opens the circuit of the winding 3S and permits the double gear to be shifted to its normal position by spring 39h into engagement with the bevel gear 32h. The arm 45 then continues its travel, as propelled by the clock mechanism, until it engages the pin 45a, as shown in Fig. 14 The user may then remove the textiles from the receiver 8 after having been washed, rinsed, water extracted therefrom and dried, as automatically controlled and carried out in proper sequence with the duration of each operation designed to give the most effective results. If, at any time, the user wishes to hasten any of these operations, the indicator arm 3 is pushed inwardly and turned in a clockwise direction to any amount desired and then released, at which time the automatic operation will resume 4its control and continue from that point on, the protective shield 49 preventing, however, any manual control of the contact arm 45 in its successive engagement with the contact strips Q, R and S for the reasons already explained.
Although preferred embodiments of this invention have been described, it will be understood that various modifications may be made without departing from the scope thereof.
