JENKINS AND EDWIN B. BISHOP, OF SACRAMENTQ, CALIFORNIA SANITARY TOILET FLUSH v Application filed October 2, 1931. Serial No. 566,412.

This invention relates to toilets and particularly to a device for actuating the flush lever or trip of the flushing apparatus.

The main object of our invention is to provide an apparatus by means of which said lever will be actuated by foot pressure. It is therefore not necessary for the user of the toilet to touch any part of the same with his hands and the device is therefore especially suitable for public toilets since it is of a very sanitary character. Theapparatus is of such a nature that it may be applied to toilets already installed, though it is preferred to incorporate the same as a built-in feature in new installations.

Further objects of the invention are to provide a device for the purpose which is easy to operate with a minimum of efiort; one in which little friction and wear are developed and there is nothing apt to get out of order;

one which is arranged so as to be easily adaptable, when being installed, to different building or toilet installation conditions; and one which is of simple and inexpensive construction. I

These objects we accomplish by means of toilet in such a position relative to the front of the toilet as to be convenient to a foot ofthe occupant.

such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawing similar characters of reference indicate corresponding parts in theseveral views installation showing our improved foot actu- 85 ated flush control device mounted in connection therewith.

Fig. 2 is an enlarged sectional elevation of the upper portion of the device taken on the line 22 of Fig. 1.

Fig. 3 is a sectional view of the cable clamping block of the actuating unit.

Referring now more particularly to the characters of reference on the drawing, the numeral 1 denotes the floor and 2 the back wall of a lavoratory, in which the toilet 3 is mounted with its flush tank 4 abutted against the wall as usual. The flushing mechanism in the tank is of that standard character which is actuated by the rotation of a transverse rod 5 projecting from the tank. In the manner.

present instance I show the foot control structure as being a built-in feature and in this case the rod 5 projects through the back instead of the front of the tank as usual. The

rod projects into the hollow space back of the wall surface and on said end is provided with a normally upwardlysloping operating arm or'lever 6. l

The foot control structure for depressing this leverto cause the toilet to be flushed is constructed as follows. v I

Dependingfrom below one lever and substantially in vertical alinement with the outer end of the same is a conduit' 7, such as a length of pipe. This conduit extends approximately to the floor level and there has threaded connection with one end of an open elbow member 8. The opposite end ofthis elbow has similar connection with a horizontal conduit 9which extends under the floor to an adjustable connection with a rectangular receptacle10. This receptacle is depressed in the floor and is provided with end brackets-11 adapted to abut against and be secured to the floor, so as to support theireceptacle in place. The receptacle is disposed to oneside of the Mounted in the receptacle is a horizontal shaft 12, extending atright angles to the axis of the conduit 9, and from which a radial arm 13 projects in the'direction of said conduit. Secured on the end of this arm is an upstanding .ball member 14 which is adapted to have a water-tight seat with an flush with the floor and is removably secured 9 to the top of the receptacle in any suitable Another. arm 17. rigid with the arm 13'depends from the shaft and has a block 18 secured. on the lower end of the same to one side of and disposed in transverse alinement with the conduit 9.

This block has a longitudinal bore to receive a cable 9 therethrough, which is adjustably clamped in place by. a screw 20 in the block. This cable extends thence through the conduit 9 about a pulley 21 mounted in the elbow 8 and up through the conduit 7.

At its upper end some distance below the upper end of said conduit the cable is connected to the lower end of a rod 22 which projects about the conduit. On its upper end the rod has a radially extending head 23 which is alined with the arm 6 and is connected to the outer end of the same by a link 24. A. compression spring 25 is disposed about the rod and is engaged at its upper end by awasher 26 fixed on the rod, and at-its lower end by cross pins 27 mounted in and projecting across the conduit on opposite sides of the rod adjacent its lower end. The spring therefore acts to hold the rod and consequently the arm 6 raised and also exerts a "constant tension on the cable, which acts to maintain the ball raised and in firm water tight contact with its seat in the gasket 15. No water therefore can get into the receptacle when the floor is scrubbed. 1

The elbow 8,which may be madewith difler- 'ent angles of bend, provides a combined pulley support and pipe connection. Being adjustably connected to the vertical conduit, the horizontal conduit and the receptacle may be disposed to any desired or necessary angle relative to the wall 2 as the conditions of installationon any particular job may require. The cable always being held under tension and elbow being rigid with the conduits, said cable will always be maintained in proper alinement and will never dragagainst the walls of the conduits. Minimum friction and wear in operation is thereforehad. I

V The top of the conduit 7 is capped by a ball 28 having a narrow slot therein of only suffi- "cient width to receive the link 24. In this 'in'a-nner the conduit is prevented frompossibly being choked up by dirt and dust dropping from above. When installing the device in connection with a toilet already in place, and ,Which would necessitate the conduit 7 being located in an exposed position in the lavoratory, said ball 28 would then be of an ornamental character.

Though particularly designed for toiletflush operation, the device is obviously adapted for connection to the valve control lever of-other lavatory equipment, such as wash bowls, etc.

1 I From the foregoing description it will be readily seen that we have produced such a device as substantially fulfills theobjects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

I Having thus described our invention what cure by Letters Patent is:

we claim as new anduseful and desire to se- 'member beyond the outer end of the horizontal conduit, and means connecting sald member and the adjacent end of the cable in a manner to cause adepression of said member to exert a pull on the cable.

2.

5. A device to actuate the depressible flush control lever of a toilet flush tank comprising a covered receptacle adapted to be mounted flush with the floor of a toilet room in ofi'set relation to the toilet, a ball in the rece tacle normally projecting upwardly throug the cover of the same, a substantially horizontal arm on one end of which the ball is secured, an arm rigid with and depending from the opposite end of the ball arm, means pivoting said arms at their adjacent ends in the re ceptacle on a horizontal axis, a clamping block mounted on the lower end of said depending arm, a cable one end of which is adjustably secured in said block and means for connecting the other end of the cable to the flush control lever.
