FLUSI-I-TANK MECHANISM.

Application filed. July 15, 1925. Serial No. 43,709.

This invention relates tomechanism for flushing tanks and refers more particularly to the mechanism for operating a closet tank flush-valve.

The principal object of this invention is to provide rectilinearly movable cam means for operating the flush-valve of a watercloset tank. Another object of the invention is to provide rectilinearly movable cam means in combination with a sliding pushpin for operating the flush-valve of a watercloset tank, 1 1

Other objects of the invention are mentioned and described herein.

The preferred embodimentof this invention is illustrated in theaccompanying drawing in which Figure 1 is a vertical section through the flushing tank showing the general arrangement of the parts; Fig. 2 is a cross-section taken on line 22 of Fig. 1; Fig. 3 is a similar view taken at right angles; and Fig. 4 is a perspective of the pushpin bearing element.

Similarly numerals of reference indicate like parts throughout the several views on the drawing.

Referring to the details of the drawing the numeral 1 indicates a fragment of a flushing tank provided with the usual discharge 2, the latter being controlled by a float-valve 3 which has the usual vertical valve stem l operatively connected with the link 5, the latter being connected with the outer end of the flush-valve lever 6.

The valve operating lever 6 is carried by the arm 7 projecting from the bearing element or plug 8, being pivotally mounted thereon at 9 intermediate its extremities to rock in a vertical plane within the flushtank. The bearing plug 8 has a polygonal portion 10 arranged within a polygonal opening 11 formed in the tank wall to prevent rotation of said bearing element. A nut 12 may be screw threaded upon and about the outer end 13 of the plug 8 to maintain its juxtaposition in the wall opening 11. The bearing plug 8 is provided with a cylindrical bore 14 extending axially therethrough at substantially right angles to the vertical plane of movement of the lever 6, a push-pin 15 being slidably arranged in said bore. The pin 15 may carry a knob 16 at its outer end to facilitate manual actuation thereof, and the inner end of said pin is provided with a conical cam element 17 rigidly mounted thereon and adapted to push-pinq15. as an abutment or stop element to limit the rock the lever 6 when-said push-pin'is. actuated. i r v The point of the conical cam 17, is prefer-- ably elongated at '18to overlie theshort end 19 of the lever 6' when the push-pinis normallyretracted by a coiltensionsprinm 20 which bears against the outer end ofthe plug '8' and against the knob 16, the butt end of said cam element normally engaging the inner face of the-plug 8 and thereby limiting the retractive movement of the The cam point 18 also serves retractive rocking movement of the lever 6 when the pin 15 is retracted by thespring 20. Obviously, forward sliding movement of the push-pin 15 will cause the conical cam 17 to move in a rectilinear path across the end of the lever section 19', whereby the latter is rocked and the ,valvefi unseated. To prevent later.al1distor.tionor. vmovement of the leveru6 when the cam 1'71 is thrustacross, lever section 19 ,anabutment, 21 is provided, said abutment being preferably formed as an extension of the arm 7 and having its face in permanent engagement with the face of the lever 6.

I claim 1. In lever mechanism for closet-tanks,

jacent said lever and movable transversely thereof and across the same. 7

2. In lever mechanism for closet-tanks,

the combination of a fixed bearing element mounted in the flush-tank wall, an arm carried by said bearing element, a flush-valve lever pivotally mounted upon said bearing element arm and oscillative in a vertical,

plane, a push-pin slidably mounted in said fixed bearing and movable transversely of the plane of movement of said flush-valve lever, a cam carried by said push-pin, whereby sliding movement of said push-pin will cause rocking movement of said lever, and an extension of said cam which overlies the flush-valve lever to limit the retractive retracted.

Within the tank, cam means associated With said bearing element and movable in a rectilinear path to cause rocking movement of said lever, and means to prevent lateral distortion or movement of said lever upon actuation of said cam'means.

4. 1n lever mechanism for closet tanks, the combination with a fixed bearing element mounted in a flush-tank Wall, said bearing element being provided with an arm,

of a pivotally mounted flush-valve lever arranged Within thetank and supported by said arm of said bearing element, cam means associatedwith said bearing element and movable in a rectilinear path to cause rock- 111g movement of said lever, and means carried bysaid bearing element armto prevent distortion or lateral movement of said lever upon. actuation of said 'cam means.

5 Inlever mechanism for closet tanks,

the combination of a fixed bearing element mounted in the flush-tank Wall, an arm carried by said bearing element, a flush-valve lever pivotally mounted upon said bearing element arm, a push-pin slidably mounted in said bearing element and movable in a rectilinear. path transversely of the plane of rocking movement of sa d lever, a conical cam carried by said push-pin, and an extension for said cam Which overlies the flush-valve lever to limit the retractive movement of the latter.

6. In a closet tank, a flush valve, a bearing element mounted in the Wall of the tank,

a push-pin slidably mounted in said bearing element and extending to the tank exterior,

7. In lever mechanism for closet tanks,

the combination of a fixed bearing element mounted in the flush-tank Wall, said bearing element being providedwith asubstantially horizontal bore open at both ends thereof,

an arm carried by said bearing element.

Within said tank, a flush-valve lever pivotally mounted upon said bearing; element arm, a push-pin slidably mounted in said bearing element bore and movable transversely of the plane of rocking movement of said lever, and a separate part conical cam carried by said push-pin at its innerend and adapted to engage and rock said flushvalve lever When said push-pin is slidably actuated.
