8 Claims.
This invention relates in general to plumbing systems, but more particularly to a system for automatically controlling the operation of flush valves in a toilet room, and the principal object of the invention is to provide a new and improved arrangement and system for electrically operating urinal flush valves at recurring time intervals.
Another object of the invention is to provide an automatic flushing system for relatively small plumbing installations in which all of the flush valve operating equipment is located in the toilet IOClm'.
A further object isto provide an automatic control device for a flush valve which can be mounted on the toilet room wall as a unit and be accessible for manual starting and stopping of the automatic flushing arrangement. v
An additional object is to provide a control device for automatically controlling the periodic operation of a flush valve and in which a manual switch is also provided for simultaneously initiating the operation of the control device and for illuminating the toilet room.
It is a further object of the invention to design a circuit arrangement for an automatic flushing system in which a manual switch is arranged to control the connection of a source of electric current with a flush valve control device andalso with the light for illuminating the toilet IdOlTl'.
With the foregoing and other objects in view, the invention consists in certain novel features of construction and arrangement of parts which will be hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which:
Fig. 1 is a perspective view of a section of a toilet room showing the invention;
Fig. 2 is a cross-sectional view of the control device;
Fig. 3 is a plan view of the control device together with the wiring; while Fig. 4 is a schematic circuit diagram of the automatic flushing installation.
In many plumbing installations it is customary to provide flush valves for the urinal fixtures, which are equipped with handles for operating the same to flush the urinal fixture after its use. However, for hygienic reasons,-persons using the urinal are reluctant to manually operate the flush valve or neglect to do so and as a result, the urinal becomes fouled and obnoxious, and constitutes a health hazard. It is therefore desirable that scme means be provided for eliminating the human element from operating the flush valve and instead provide means for automatically flushing the urinal at periodic intervals. In accordance with applicants invention, the manually operated handle on the flush valve is replaced with an automatic means such as anelectric device in the form of a synchronous motor which is arranged to operate the flush valve to flush the urinal fixture. The flush valve motor ifs-controlled by a timing device which at periodiearmterva s energizes the flush Valve motor. Preferably the timing device is mounted at the usual height for a wall switch adjacent the entrance door to thetoilet room and an electric wall switch in the timing device is adapted to be operated by a person entering the washroom to start the automatic timing device into operation. The switch is alsoconnected in parallel with the light for illuminating the toilet room so that the first person entering the toilet room in the morning', for example, 'will operat'ethe wall switch to start the automatic flushing and at the same time 'illuminatethe room. The last person using the room in the evening would disconnect the systern by operating the Wall switch to its fo'fff position. This could be done by a janitor or watc m'an making the rounds of a building. By om biriing the control of the toilet room light and the timer into a singl'e switch, an important object of the invention is obtained, in that sepa rate control switches are not required and the simple act of operating one switch, which 'n'a't-' ura l lly done by a person entering the toilet room to illuminate the same, will aisle start the automatic flushing system into operation. L
It preferable and desirable that the timing device be arranged so that it can be readily mounted and supported within a standard conduit box customarily used for enclosing wall switches, thereby rendering the timing dev ce inc onfs'picu ousl, compact, and requiring no special mounting space in the toilet room. ,1 I r K t Beferring to Fig. 1 of the drawing, the toilet room is indicated in' fragrnentary perspective at 5, againstthe wall of which a urinal fixture: Q of any well-known constructionmay be supported. A hydraulic flush valve '1 a lso o'f kn wncenstme tion, has its outlet connected directly to the top of the urinal {land in place of the us ai manuany' operated handle the valve 1s prv1eea with an electric operating device 8, preferably the form of a synchronous motor, suchas" is disclosed in patent application Serial blumber 653,507, filed March 11, Q46. A watersupply header orpipe 9, controlled by the customary shut-oil valve, connects to, the inlet side of the flush valve b The electrictimerindicated generallyat [0, is mounted onthe wall; of the tpiletroom 5 as shown. Suitable electrical conduitor pipe, ;indi cated at ll, connects the timing device ID with a junction box 12 located in the vicinity .of-the flush valve motor 8 and an electrical supply conduit I3" is connected to the timer it. Th'ejunc tion box [2 has another conduitconnected to it which, extends to an electric illuminating light M which serves to illuminate the toilet roorn when required. The electric timer 10 is preferably located on the wall adjacent the entrance door I of the toilet room.
The electric timer I0 is preferably mounted in a standard electric conduit box or housing indicated at I6 in Fig. 2, which box is recessed in the plastered wall I! of the toilet room. The usual mounting brackets I8 support the box I6 on the wall. After the conduit box I6 is mounted into position, the conduits I3 and II are secured in the well-known manner by the nuts to the side wall of the box I6, as shown in Fig. 3. The wires are then fed through the conduit and the ends left free in the conduit box I6.
The timing device ID as a unit is supported by a U-shaped mounting plate 2|, the sides of which fit snugly within the conduit box I6, while the ends 22 are bentoutward so that they overlap the ears I9 of the conduit box. Screws 26 are then passed through the coinciding screw holes in the ears I9 and the bracket end 22. In this manner, the timing device is supported as a unit in the conduit box. The timing device includes a small synchronous motor 23 of any well-known construction having a terminal block 24 on the side thereof, through which the incoming Wires for the motor are attached. The motor is mounted on the rear side of mounting plate 2| by a series of screws 25. Suitable gearing is incorporated in the motor 23, one of which gears extends through the mounting plate 2| through the front side thereof for rotating a cam 26. This cam consists preferably of two overlapping discs adjustably held together by the screw 2'! so that the cam notch in the disc can be adjusted to any desired width. The notch in cam 26 upon rotating is adapted to actuate a switch lever arm 28 pivoted to snap action switch 29 of any wellknown construction. The snap acting switch 29 is supported as by screws 39 on the front side of mounting plate 2|.
A toggle switch 3| of any desired well-known form is mounted on the left-hand side of the timer unit Ill in the conduit box I6, as shown in Fig. 3, and is held to the conduit box by screws on opposite ends of the switch as shown. A cover or wall plate 32 fitting flush with the wall surface of the toilet room and of usual construction covers the equipment in the conduit box I6. It is held in place by screws 33 threading into ears 34 of the bracket 2| and similar screw openings in the face of the toggle switch 3 I. Referring now toFig. 4, this shows the schematic wiring diagram of the arrangement for operating the system, the actual wiring of the timing device being shown in Fig. 3. The alternating current supply line 36 and 3'! preferably of 115 volt, 60 cycle, extends through the conduit I3 to the conduit box I6 and the timing device. The supply line 31 extends in series through the toggle switch 3|, wire 38, cam switch contact 29, wire 39 to the winding of the flush valve motor 8, and back over the return lead 36. A branch circuit 40 extends in parallel with the electric light I4 and the timer motor winding 23 is also connected across the foregoing circuit.
The flush valve motor 8 consists of the motor 4| and its associated winding, a set of gears 42, and a cam 43 which is adapted when rotated to actuate the plunger 44. Plunger 44 in wellknown operation of flush valves actuates the auxiliary valve stem 45 and thereby causes the hydraulic operation of the flush valve I, flushing the urinal fixture 6. Further details of the flush valve motor operation may be had from the aforementioned application.
The operation and use of the device and system is as follows:
Assuming the toggle switch 3| is in the 011" position, a person entering the toilet room through door I5 will find the same usually dark and therefore operates the toggle switch 3| which is immediately accessible as the door is opened. This action completes a circuit over the now closed contacts of toggle switch 3|, the current supply line wires 36 and 37, and the wires 40 leading to the lamp I4, thereby illuminating the same. A branch of this circuit also extends to the timing motor 23 starting the operation of the timing device. At predetermined intervals, for example, every five minutes, the cam 26 is rotated by the timer motor 23 to a position where the cam notch operates the switch lever arm 28 causing the closure of the snap switch contacts 29. This action completes an energizing circuit for the flush valve motor 8 over a circuit path extending from the electric supply line 31, closed toggle switch 3|, wire 38, snap switch contacts 29, wire 39, winding of flush valve motor 4|, return lead 36 to the supply line. As a result, the flush valve motor 8 is caused to actuate its cam 43, resulting in a flushing action of the flush valve I upon the urinal fixture 6. The engagement of the cam notch with the snap switch lever 28 is of such a duration, for example, five seconds, that contacts 29 are closed for that length of time, which enables the flush valve motor 4| to rotate its cam 43 at least one full revolution. After the contacts 29 are opened, the flush valve motor 8 stops rotating and the flush valve I completes its cycle of operation. Thereafter, at the stated five-minute intervals, the timer motor 23 will cause the preceding action to take place, and cause the periodic flushing of the urinal fixture 6.
The electric light I4 in the room continues to remain illuminated and is not affected by the operation of the timer device or the flush valve motor 8. The automatic flushing action will preferably take place throughout the duration of the daytime period for example, when the use of the urinal fixture is most frequent. After working hours, or when less frequent use of the urinal is desired, the toggle switch 3| is snapped to its oif position completely de-energizing the system and disconnecting the timer motor 23 and the lamp I4 from the supply line 36 and 37. The system remains dormant until the toggle switch 3| is again actuated.
In certain cases it may not be desirable or advantageous to provide a combination switch 3| for both the electric lamp I4 and the flush valve motor 8. In that event a separate small indicating lamp 50 may be mounted in the conduit box I6 as shown in Fig. 4, to indicate whether the automatic flushing system is in its operating position or has been disconnected.
Preferably the synchronous motor will have a speed of ten R. P. M. and the timing device will be set to operate the motor at five-minute intervals, and at each interval will operate the motor for a period of from three to five seconds.
While only a preferred embodiment of the invention has been illustrated and described, it will be appreciated that modifications of the same may be made by those skilled in the art.
