To all whom#mug/concern:
Be it known that I. `WILLIAM Srrnnwoon,
citizen of the UnitedStates, residing` at Detroit county of Elayne, State of Michigan, have inventeda certain new and useful lmprovenientI in Flush Valves, and declare the i shown in the accompanying drawings and Vmore particularly described 1n the following specification and claims. y
One of the objects of the present invention is to provide a device of simple and inexpensive construction which is adapted to automatically hold the valve upon its seat until manually raised and then to automatically maintain the valve oft its seat until the water contained in t-he tank is substantially discharged, whereupon the valve is automatically seated and held upon its sea-t that the tank may be filled or until again Inanually raised to discharge the water in the tank.
A further object of the invention is to provide a device ofA few parts which are readily accessible for examination or repairs when required.
A further object of this invention is the` elimination of springs or other like devices to force the valve to itsseat and to maintain it thereon.
Other features of this invention are the means for manually controlling the' raising of the valve from its seat, and for guiding the valve back to its seat.
With the foregoing and other objects in view which will appear as the description proceeds, the invention further resides in the combinationv and arrangement of parts and in the details of construction hereinafter y described and claimed, it being understood that changes may bey made in the precise embodiment of the invention herein disclosed without departing from the spiritof the.
same.
In the drawings accompanying this specication; y i A Figure 1 is a sectional view through a fragment of a flush tank showing the iiush vvalve closed and dotted lines the position ,dushvalve` u v Referringnow to the letters of. reference of the iioat upon manually raising the valve by the operation of the controlling lever,
Figure 2 is a similar view, showing the 4 valve as .it ywould appear .when supported Aby the action ofy the fioatwfollowing the manual raising` of the valve to discharge thek` water from the tank.
Figure 3 is a perspective viewer 'the lever mechanisim-.fmountedon the upper end of y the overflow pipefor manually raising the placed upon the ldrawings L A', denotesy `al flush tank;y theI discharge" outlet lprovided with a valveseat B to re-y ceive the flush valve C, iitted on its underside with a leather or other suitable disc Cf. i
D indicates a stem, threaded to receive a nut a, extending up through the valve with an aperture at its upper end to receive thef end of a wire link E, connected with one rarm ot' a bell-crank lever F, pivoted to a casting clamped upon the upper end of the overow pipe H ;-which is supported in w an extension of the iitting B forming the discharge outlet. I, denotes a manually operated "rocker arm journaledin the wall of the tank ;-`the arm on the inner wall of the tank being adapted to bear upon a roller 1 i F on one arm of the bell-crank lever F for operatingl the latterto lift the Hush valve.
J, designates a bracket, clamped to the casting M adapted to enter a peripheral groove D in the valve stem D to support y the valve oii7 its seat when manually raised (see Fig. 2) until the altitude of the water i in the tank has been suiiiciently lowered to cause the fioat at the end of theplever to release the valveby tripping the valve supporting hook M.
When seated the valve is held thereon (until manually raised) by the combined` action of the float and the hook-shaped casting M, (see Figure l).
N denotes a rod, supported in a bracket i projecting from the inner wall of the discharge outlet casting, extending upwardly yinto a bore provided in the stem'D, for
guiding the valve to its seat. v
Having indicated the several parts by reference letters the lconstruction and operation et the devieewll he readily understand..
vim
To discharge the water from the tank the rocking arm I is manually operated thereby actuating the lbell-,crank lever vF, which in turn, through the link connection E, serves to lift the flush valve C. Upon the valve being raised to discharge the water the float L forces thehook M to enter the groove D in the valve stem D, thereby maintaining the valve in its elevated position until the float is no longer effective to maintain the hook M in the groove D to support the `valvein its elevated position.
The valve being thus released drops to its Lseat whereupon the hook M closesv over the end of the valve stein' as sho-wnin Figure l, the float serving to hold the valve to its seat while the tank is filling and until the valve is again manually raisedas previously eX- plained. ,n A. Y
Having 'thus described my invention `what -I claim is 1. In a device of the character described anV overflow pipe carrying spaced brackets thereon composed' of laterally extending arms,`,asubstantially inverted V-shaped bell Y crank having one` arm pivoted to the said bracket and carrying "a link on the other arm, a lever carrying a roller atone end connected to the bell crank at the point of intersection of the said arms and extending below the pivotpoint of thesame to the bracket, a
vertically sliding valve carried by the lowerv whereby the valve is held closed and means forraising and lowering the valve.4 o
` In testimony whereof-,JI sign this specilication in the presence of two witnesses.
