This invention relates to a rug or Carpet cleaning machine. K

The. principal object of the invention 1s to provide a machine. which throughoutis automatically controlled, so that it will clean a rug, vcarpet or the. like, after the latter is properly mounted in themachine, with practically no attention until the cleaning process is completed. This automatic characteristic ofthe machine applies to all parts thereof including. means for beating a rug or carpet, the means for suction cleaning it, the meansfor scrubbing it, and the means for .steaming it. The arrangement also is such that any of these separate means may be disused or rendered inoperative when desired in the treatment of the rug or carpet.

This machineA clean-s onezone or strip of a rub or carpet during one cycle of movement of a rub in -the machine, that is, during the movementgof the rug in one direction through the machine and the reverse movement thereof. Then the machine automatically shifts the cleaning means to another Zone and the process is continued until all zones or strips of the rug have been cleaned and then the machine stops automatically.

Such a. machine materially reduces the labor required in cleaning rugs, as one man could operate ten machines if desired, for no attention is given to the operation of any machine until the rug is cleaned. Furthermore, it is unusually economical in Hoor space because it is an upright machine so that the -width of the machine is only three or four feet.

It requires a very short time, approximately eight minutes, to clean a 9 ft. 12 tt. rug. The only labor consists in placing the rug in the machine and taking it out.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims:

In the drawings Fig. 1 is a front elevation ofthe machine with an intermediate por-` tion from top to bottom being broken away. Fig. 2 is aside elevation of the left hand lend of the machine as shown in Fig. 1. Fig. 3 is an elevation of the right hand end of the machine as shown in Fig. 1. Fig. 4 is a vertical section taken on the line 4 4 of Fig. 1 showing a beater attachment connected therewith. Fig. 5 is the same as the left hand part-of Fig. 1 showing the scrubbing attachment partly broken away, and the cleaning fluid tank connected therewith, the remainder of the machine being broken away. Fig. 6 is a vertical section on the line 6*(5 of Fig. 5. Fig. 7 is a rear elevation of the beating attachment, which is shown in side elevation in Fig. 4. Fig. 8 is a rear elevation on avlarger scale of the mechanism at the left hand end of Fig. 5, the remainder of the machine being broken away. Fig. 9 is a section on the line 9 9 of Fig. 8. Fig. 10 is a horizontal section on the line 10--10 of Fig. 3 showing the steaming attachment. Fig. 11 is a front elevation of what is shown in Fig. 10. Fig. 12 is a longitudinal section through the left'hand end of the steaming pipe on a large scale and showing means for regulating the width of the steam line. Fig. 13 is a side elevation of the upper part of Fig. 8 with some parts omitted in order to make the remaining parts more clear.

The main frame, which is stationary, consists of an upright 10 at the left hand end of the machine and anupright 11 at the other end of the machine, said uprights being angle irons. and three tubular brace bars 12, 13 and 14. Said uprights l() and 11 are mounted in connection with foot pieces 16 at each end as shown in Figs. 2 and 3 and the frame is maintained upright by diagonal braces 15 extending between the uprights and the base bars or foot pieces 16.

In said frame, top and bottom rolls 20 and 21 are mounted on shafts 22 in suitable bearings 23 at each end of the frame. carpet with a worm 29 in turn driven through a shaft of an electric motor 31. The motor 31 is mounted on a bracket 32 secured to and between the frame bars 19 and 98 at the left hand end of Fig. 1. Each of the gears 24 is clutched to its respective shaft 22 by means of a clutch 38 of a well known form. When the upper clutch 38 is engaged the roll 20 is rotated to wrap the rug thereon. When the lower clutch 38 is engaged the lower roll 21 is rotated in the opposite direction to wrapv the rugV upon that roll.

The means for controlling the roll-driving clutches includes the hand lever 33 vat the right hand end of the machine as shown in Fig. 1 and the lever 233 at the left hand side, shown in Figs. 1 and 2. The lever 33 is fulcrumed at its lower end to the bracket 34 and said lever is pivotally connected with a sh1fting rod 35 extending through the tubular brace 13 to the other end of the machine. The rod 35 is connected with the clutch-shifting bar 36 which is fulcrumed between its ends at 37. Said fulcrum is located between the rolls 20 and 21 so that said bar 36 will operate to engage one clutch 38 and simultaneously release the opposite clutch 38 so that the rug may be selectively rolled upon either roll. The lever 233 is connected to the bar 36 by means of a bar 122, bell crank 125 and link 127. Thus the roll-driving clutches may be operated either by lever 33 or lever 233 from either end of the machine.

The lever 233 extends forward from the machine as seen in Fig. 2, and is fulcrumed at 39 on arm 139 secured to the upright 10 of the frame, and said lever 233 between its ends engages the bar 122 so that when the end of hand lever 233 is moved down, as in Fig. 2, it will operate clutch lever 36 and release one roll clutch 38 and move the other into clutching position, that is, changev the clutches 38 from the positions shown in Figs. 1 and 5 to the position shown in Fig. 8, or the reverse. This will reverse the vertical movement of the rug. When the clutches are as shown in Figs. 1 and 5, the lower roll will operate to wind the rug downward and when the clutches are as in Fig. 8 the upper roll will operate and wind the rug upward.

In order to place the rug 40 into the machine to be cleaned, it is placed on the floor in front of the machine, one end is lifted up by hand and clamped in a series of clamps 41 secured on a horizontal metal strip 42 which is supported by straps 43 made of fabric or leather in turn secured on the upper roll 20. The straps 43 have a length somewhat greater than the circumference of the rolls to which they are secured. Then the machine is started by operating either hand lever 33 or 233 and the rug or carpet is rolled upon the upper roll. The free end of the rug, which is then hanging downward, is likewise secured to a similar set of clamps 41 on similar horizontal metal strips 42 mounted in connection with the lower roll 21 by a similar set of straps 43.

The rug is made taut or put under tension by means hereafter explained.

If the rug has been used in a clean town or neighborhood or situation, it can be cleaned by the use of the vacuum means or nozzle as shown in Fig. 1, without the necessity of beating or scrubbing. To that end, there is provided a vacuum nozzle supported at each end by a bar 51 to which it is pivotally mounted and the same suspended from a carriage 52 which is slidably mounted on the brace tube 12 serving as a bar or the like of the frame, as shown, so that the vacuum nozzle may slide longitudinally of the machine and the vacuum nozzle put in engagement with the surface of the rug. The side elevation shown in Fig. 4 will give a better understanding of the foregoing construction. As there shown, when the rug holding rolls 2O and 21 move the rug when vertical, the cleaning means is, by gravity, maintained in engagement with the face of the rug. There we see a suction tube 53 which may be either a single or branch suction tube leading from a main suction tube 54 shown in Figs. 1 and 2 which is connected with the upper end of a vacuum tank 55, see Fig. 2. The air is exhausted from the upper end of the vacuum tank 55 by an exhaust pipe 56 running through a vacuum pump 57 and out through a discharge pipe 58. The vacuum pump 57 is driven by a belt 59 running from a motor 60.

In the upper end of the tank 55 there is a baiie plate 61 extending down a short distance from the top of the tank and located between the intake and the exhaust so that the incoming air is deflected downward for facilitating the separation of the dust, dirt and other heavier foreign particles therefrom. Such foreign matter drops down on the bottom 155 of the tank and may be removed by a lclean-out door 62. Thus no foreign matter will pass therethrough to damage the vacuum pump. The tank 55 is supported by a plurality of legs 63 extending up from the floor 64.

The suction nozzle 50 is not vertically movable but is laterally movable by a carriage on the bar 12 as indicated in Fig. 1. Said carriage may be moved by hand by operating a crank 66 at the upper right hand corner of the machine as shown in Fig. 1, or by a hand wheel 67 at the other upper corner of the machine. Said crank 66 operates a sprocket wheel 68 that is mounted'in a bracket 69 secured on the upright 11. The hand wheel 67 is also mounted in a bracket 70 from the upright 10 of the frame and turns a sprocket wheel 71. An endless sprocket chain 72 is mounted on said sprockets 68 and 71 and maintained in horizontal position immediately above the carriage 52 and is operatively connected with the carriage 52 by a stirrup 73 which extends'upward from the carriage 52 and is seemed at its lower end thereto. The upper side of the chain 72 .rides on a roller 74 in said stirrup and suitable-means is provided for removably connecting said stirrup with the chain 72 whereby it can be readily connected or disconnected or shifted somewhat.

Such means as shown in Fig. 1 consists of a pin 75 extending up from the bottom of the stirrup 73 into the space between the adjacent. ends of links, and a tapered key 76 extending through the stirrup and resting on the link of the chain above said pin. This enables the chain and carriage 52 to be relatively shifted as desired.

-In the operation of the machine, after a rug has been attached thereto, the suction nozzle carriage 52 is shifted to the left hand end of the machine, preferably by means of the hand wheel 67. The said carriage remains in that position while the rug is automatically wound from one roll to the other and return and the lefthand strip orv portion of the rug is thereby cleaned. The carriage 52 is then automatically shifted in a horizontal direction or transversely of the machine to engage another portion or zone of the rug for cleaning. In the new position, the rug is again wound from one roll to the other and return, after which another movement of the carriage 52 takes place. The intermittent movement of the carriage is continued until the rug is entirely cleaned.

The mechanism for automatically reversing the direction of rotation of the rolls 20 and 21 for winding the rug alternately from one to the other will now be described with special reference to Figs. 8 and 9:

Each of the rolls 20 and 21 is provided with a spring bar 106 (seen in Fig. 8) which is normally pressed against the roll when a rug is wound thereon. When the rug is unwound from either roll, the spring bar associated therewith is free to spring outwardly to engage a notch 107 in a pull bar 108. Each of said pull bars is pivotally fastened at one end to a link 257 which is in turn pivoted upon the frame member 10.

Each pull bar 108 is slotted at its opposite end 109 to receive a. bolt 110 carried by an irregular shaped lever 111, each of which levers is in turn fulcrumed vupon the frame member 10 at 112. A tension spring 113 connects each bar 108 with the corresponding lever 111. When either of the bars-108 is moved by the spring 106, the spring 113 bars 114 both of which are ulcrumed upon a block 258 carried upon one end of a lever in turn fulerumed upon frame member 10 at 118. A air of leaf springs 259 also fastened upon t e block 258 serve to urge the bars 114 to the right in Fig. 9 against suitable stops upon the block 258. Each of the bars 114 carries a dog 116 which is moved to engage a ratchet wheel 115 when the corresponding bar 114 is moved by its lever 111. Each of the ratchet wheels 115 is formed integrally with one of the bevel gears 24 and runs freely upon its shaft 22 unless the corresponding clutch 38 is in engagement. The said ratchet wheels are therefore continuously rotated in the direction of the broken arrows in Fig. 9. By this mechanism, when the rug has been unwound from the lower roll 21, the lower bar 114 is pressed inwardly against the action of its spring 259 to engage the lower dog 116 with the lower ratchet wheel 115. The bars 114 are thereby pushed upwardly and the leverv85 is rocked in a counter-clockwise direction. Similarly, when the rug has been unwound from the upper roll 20, the lever 85 is rocked in a clockwise direct-ion.

At the oppositevend of lever 85, a yoke 119 is fastened by means of a pin 89 and the said yoke is secured on the upper end of a rod120 extending downwardly through an opening in an arm 121. The rod 120 is adjustably held in position upon said arm by adjustable collars 123. The arm 121 is carried upon a vertical bar 122 slidably mounted upon the frame member '10 by means of guides 124. The lower end of said bar'is pivoted to a bell crank 125, fulcruined upon the upright 10 at 126 and in turn connected by a link 127 to the clutch-shifting lever 36. By this means, when the rug has been unwound from the lower roll and the lever 85 has been rocked counterclockwise, the shifting lever 36 is moved to engage the lower clutch 38 and disengage the upper clutch 38. The direction 4of rotation of the rolls is thereby reversed and the rug is then wound from the upper to the lower roll. Similarly, when the rug has been unwound from the upper roll, the shifting lever 36 is moved to disengage the lower clutch and to engage the upper clutch.

The mechanism by which the automatic movement of the carriage 52 is performed will now be described with special reference to Figs. 8, 9 and 13:

A bevel gear 168 carried upon a horizontal shaft 250 is continuously driven by one of the bevel gears 25 carried by the shaft 26. The shaft 250 also carries a sprocket 251 about which is trained a sprocket chain 252. The

llt

'When the said clutch members are chain 252 is also trained about a-sprocket 253 -which forms part of a clutch member 100 are engaged, the chain 72 is, therefore, op-

erated to move the suction nozzle carria le 52.

isengaged the carriage 52 remains stationary.

For shifting the clutch member 100, a shiftin lever 101 is provided. The said lever is fu crumed upon an arm 102 rigidly attached to the upper end of the frame member 10.

A tension spring 104 is attached to one end of the shifting lever 101 and its opposite end is attached to an arm 105 carried -upon tlie bearing 81. The said spring serves to urge the lever 101 in the proper direction to engage the clutch member 100 with the mating member 254.

A link 103 is pivotally attached to the lever 101 and its opposite end is pivotally connected at 95 to a pair of levers 94 and 96. The lever 94 has a free end extending outwardl as shown particularly in Figs. 8 and 13. he lever 96 is fulcrumed at 99 upon a frame member 98 and has a free end p'rojecting inwardly beneath tliesprocket 71. By means of these levers, the link 103 may be forced downwardly to move lever 101 in the proper direction to disengage the clutch members 100 and 254. v

The lower end of lever 94 terminates in a hook portion adapted to engage an angle member 94a attached to the frame member 10. When the lever 94 is moved to engage the said angle member, as shown in Fig. 8, the link 103 is moved downwardly and the lever 101 is rocked against the action of spring 104 to disengage the clutch members 100 and 254. The clutch is thereby locked out of engagement and the carriage 52 remains in a stationary position until it is desired to start the machine, at which time lever 94 is manually disengaged from the angle member 94a as shown in Fig. 13. When so disengaged, the spring 104 draws the clutch into engagement and also elevates the free end of lever 96 into the path of travel of a plurality of lugs 97 carried upon the chain 72. `When one of said lugs engages the lever 96 in the movement of chain 72, the said lever is depressed sufficiently to disengage the clutch and stop the carriage but not sufficiently to latch the lower encl'of lever 94 beneath the angle 94a. The lugs 97 are properly spaced upon the chain 72 to stop the carriage in position for the cleaning of each zone of the' rug. l

A ratchet wheel 83 is fastened upon the shaft 80. The said ratchet wheel is engaged by the p'awl-shaped upper end of a vertical bar 84, the lower end vof which is pivotally fastened to t-he lever 85 by the pin 89. The said bar 84 extends loosely throu h a stirrup bar 87 near its upper end an is spring pressed toward the ratchet wheel 83vby a torsion spring 88 coiled about the pin 89 and having an upwardly-extending portion engaging said bar.

At the end of each complete movement of the rug upon the rollers, the bar 84 is vertically reciprocated by the rocking of the lever 85 previously described. Each reciprocation of the said bar moves the ratchet wheel and shaft 80 vthrou h a distance represented by 'one tooth of t e said ratchet wheel. This movement of the shaft 80 is effective to move the lug 97 away from the end of the lever 96. When the lug 97 is so moved, the spring 104 is free to draw the clutch into engagement and the chain 72 is moved a suflicient distance to bring the next of the lugs 97 into engagement with the lever 96. Thereupon, the said lever is again actuated to disengage the clutch. By this meansthe carriage 52 remains stationary at each of predetermined positions until the rug has been wound from one roller to the other and return and, at the end of each winding operation, the movement of the carriage4 to its next predetermined position is automatically actuated. By a suitable choice of the size of theteeth of ratchet 83 and the length of travel of the vertical bar 84, the machine may be adjusted so that the rug may b e wound from one roll to the other several tlmes at each of the predetermined positions of the carriage 52 if desired.

When the carriage 52 reaches the extreme right hand end `of the machine, it engages a stop member 255, shown in Fig. 1, whlch is carried upon a horizontal rod 91. The opposite end of said rod is supported upon the upper endof the frame member 10 as shown 1n Fig. 8 and carries an arm 92 in turn carrymg a link 93 which is attached to the lower portion of the lever 94.

The movement of the rod 91, upon engagement of the carriage 52 withthe stop member 255, therefore, moves the lever 94 from the position shown in Fig. 13 to that shown in Fig. 8, thereby disengagin the clutch members and 254 and latcglriing the lever 94 beneath angle 94a to prevent further movement of the carriage. At the same time, a dog 90 carried by rod 91 engages the verti-I cal'bar 84 and moves the same against the action of the spring 88 out of engagement with the teeth of ratchet wheel 83. Thus, when the carriage 52 reaches the extreme right hand limit of travel, the clutch and the `bar 84 are both rendered inoperative to move it further. The same result may be accomplished manually at any desired point in the operation by means of a lever 256 attached to the rod 91 and the frame member 11 as shown in Fig. 1.

VEach roll 20 and 21, when idle, is held taut by a friction brake as seen in the right hand end of Fig. 1. There is shown on the ends of the two rolls 2O and 21 a collar 133 which serves as a brake band and is engaged by the brake shoe-13.4 which is controlled by a lever 135 shown in Fig. 3 thatis actuated by a connecting bar 136 in Fig. 1 to a b'ell crank lever 137 and link 138 from the hand lever 33. When the lever 135 is in the position shown in Fig. 3, the upper brake shoe 134 is set and.

the lower brake shoe 134 is released. The lever135 is connected with the brake shoes by a tube 140 into which a rod 141 is slidable and it is spring-pressed outward bya spring 142 which is properly connected with the brake shoe 134 as seen in Fig. 3.

rPhe cleaning nozzle is short compared with the horizontal dimensions of the rug so that while the cleaner remains stationary and in engagement with the face of the rug it will clean one zone or strip during a round tripmovement of the rug and then the cleaner is moved in position to clean the adjacent strip or zone of the rug during its next roundtrip or movement.

. The beater carriage is illustrated in Figs. 4 and 7 and consists of a frame formed of upi rights 145, cross bars 146 and diagonal braces 147. It is mounted on sheaves 148 that'travel on the tubular brace 13 as seen in Figs. 1 and 4. The upper parts of the bars 145 are bent horizontally as shown in Fig. 6 vand are secured to the underside of the carriage '52 heretofore described. Uponl the horizontal portion of said bars 145, plate 150 is secured, which supports an electric motor 151. Power is taken from the motor through a belt 152 to a pulley 153 which drives a shaft 154 on which is mounted a pair of cams 155. As said cams revolve in the direction indicated by arrows in Figs. 4 and 6, they strike fingers 156 secured on hollow tubes or shafts 157 that are held in a bar support 158. Said iingers 156 are rigidly connected with beaters 160, which are loop-shaped as shown in Fig.

7, and are adapted to engage and beat the rear side of the rug directly opposite the slot in the suction nozzle 50 seen in Fig. 4. The beaters are forced against the rug by means of springs 159 secured thereto and anchored to the heater carriage, the cams 155 serving to move the beater away from the rug. Beaters 160 are held in idle position by hooks 161, as shown in Figs. 6 and'7. The two beaters illustrated are mounted on independent shafts and may be adjusted to beat alternately or simult-aneously by adjusting the position of cams 155.

The scrubbing means is illustrated in Figs.

5 and 6 Where there is shown a scrubbing brush 165 extending longitudinally of the machine and which engages the rug 40. Itl

is mounted at each end in a bracket 166 and is reciprocated by a connecting bar 167 shown in Fig. 5 which is pivoted eccentrically to a bevelled gear 168 driven by the pinion 25.

The scrubbing brush 165 is supplied with soapy water or the like from a tank V170 through a hose 171 and a pipe 172, from which the cleansing fluid trickles onto the bristles of the scrubbing brush. Suitable means for supporting said tank 170 is provided but 'it is not shown herewith. The cleansing iuid drips or drains down into a drain trough 173 which rests on the floor. When the scrubbing brush 165 is not used, it is lifted up oif the brackets 165 shown in Fig. 6 and folded down out of the way by means of a bar 174 which is secured to the brush member 165 and which, at its lower end, is pivoted to a link bar 175 that is pivoted to the supporting tube 13. 1

After the rug has been beaten and scrubbed, it is steamed by the means shown in Figs. 3, 10 and 12. Steam comes from a boiler room, not shown, through a pipe 180, see Fig. 1, and it is controlled by a hand valve 181. The steam passes into a steam'tube 182 that eX- tends the full length of the machine and is provided throughout its length with perforations-183 for the escape of the steam to the rug. The steam is admitted into the right hand end of the tube 182, as shown in Fig. 10, and the other end of said tube is closed.

The right 'hand end of the tube 182 screws into a head 184 as shown in Fig. 11.V yA steam pipe connection 186 leads from the valve 181 and carries steam which it introduces into the tube 182. The pipe connection 186 is mounted in a swivel connection 187 which extends through a bracket 188 and has secured on it a handle 189, whereby the steam tube can be elevated into the horizontal position for use and be held in that position by a leaf spring 190 shown in Fig. 3, or the tube 182 can be turned down out of the way. A head 185 at the left hand end of the tube 182 is pivoted at 191 so as to cause both ends of the tube to swing down or up as the lever 189 may be operated.

The steamer is positioned as in use in Fig. 3. Means is provided for regulating the width of rug surface that it steams as illustrated particularly in Fig. 12. In each end of the steam tube 182, there is mounted a long tapered sleeve valve 193 which is tubular at the outer end. The valves 193 extend for some distance into the tube 182 and their v secured a handle 196. The valve 193 at the right hand end of the tube 182, is secured on a head 197 that is similar to the head 194: excepting that it is perforated to admit steam and it-.is operated by a similar hand lever 196 and shaft 195. When the valves 193 are located as shown in Fig. 12, the tube 182 wouldsteam for about one-half its length, but if the valves were turned so as to open all the ports 183, the steam would operate throughout the entire length of the tube 182, as shown in Fig. 11.

We have described herein means for beating, suction cleaning, scrubbing and steaming the rug and usually the rug goes through all of said rocesses of treatment, but often some of sai steps in the process are omitted, according to the nature of the rug, and it is noted that this machine is so arranged as to enable any of said cleaning steps to be used or not, as desired. It is also noted that this machine is completely automatically or mechanically operated, although it may be hand controlled, if desired.
