BY 142 v awayzwyefi Patented Jan. 12, 1943 rwsu TANK VALVE Arthur N. Asselin, Fall River, Mass. Application October 1,1941, Serial No. 414,010 4 Claims. '(01. 131-404) This invention relates to a flush tank valve of the ball cock type described in my copending application filed April '7, 1941, Serial No. 387,354.
An object of the present invention is to provide a combined opening and closing device which will eliminate noise, as the valve is closed by the flush tank float.
A further object is to provide a vacuum breaker for a flush tank valve adapted to prevent the suction of the water out of the flush tank by vacuum created'when the supply of water is shut off in the supply pipe.
A further object is to provide apparatus of this character which will be formed of a few strong, simple and durable parts, which will be inexpensive to manufacture, and which will not easily get out of order.
With the above and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages oi. the invention.
In the accompanying drawings forming a part of this specification: v
Figure l is a longitudinal sectional view of a flush tank valve constructed in accordance with the invention, shown in full lines fully closed,
and in dotted lines showing the plunger valve in position to register the air inlet openings with the openings in the wall of the valve hearing so that atmospheric air may break the vacuum action and prevent water being sucked out of the flush tank when the water supply is cut on.
Figure 2 is a longitudinal sectional view of the valve shown fully open.
Figure 3 is an end elevation of the flush tank valve looking from the direction of the float.
Figure 4 is a longitudinal sectional view of "the flush tank valve showing the coacting cam-proiections on the silencing lever and valve operating lever a few seconds before the float rises suillciently to close the valve. s
Figure 5 is a longitudinal sectional view similar to Figure 4 but showing the silencing lever and valve operating lever in position to provide a small gap between the valve and its seat momentarily as the valve is being completely closed so that water hammering will be prevented.
Figure 6 is a detail perspective view of the plunger valve. 1
Figure '7 is a longitudinal sectional view of a modified form of the invention in which a plug is equipped with a vacuum valve adapted to be screwed into the supply pipeinstead of being built into the plunger valve.
Referring now to the drawing in which like characters oi! reference designate similar parts in the various views, It designates a flush tank valve body, the same having a water inlet nozzle H, adapted to receive a supply pipe l2 for filling the flush tank. The body is provided with a longitudinal bore l3 having a nipple H to receive a siphoning tube l5, and diametrically opposite the nipple the body is provided with a nipple l6 which communicates with the bore and receives the filling pipe H for the tank. A tubular valve cage ll is removably mounted in the bore and is provided with openings I! which establish communication between the bore of the cage and the bore of the valve body so that water may exit through the siphoning tube i5 and the filling pipe H. A washer nut II is threaded into the bore of the body and confines the cage in place.
A plunger valve 2| is mounted in the bore of the cage and projects through the washer 20. The plunger valve is cylindrical and hollow, set
Figure 6, and is provided with air inlet openings 22 the purpose of which will presently be explained. The plunger valve is provided with a stem 23 of reduced diameter which extends through the bore of the cage and is rovided with a disk valve 24 having a beveled p rtion 2! 1 adapted to seat against a beveled valve seat 20' formed on the valve cage.
When the plunger valve is fully closed as shown in Figure l, and also when the, plunger valve is fully open as shown in Figure 2, the aforesaid inlet openings 22 are masked by the wall of the I bore of the cage ll. However, when the water supply is cut oil from the supply pipe II with resultant suction being created in the nozzle II the plunger valve will be moved forwardly to the dotted line position shown in .Figure 1 at which time it sealsa water inlet opening 21 and is stopped against further movement by the diaphragm 2B in which the opening is formed.- At
this time the air inlet openings 22, of which preferably there re four, will be moved into registration with tug. atmospheric air ay equalize through the hollow plunger valve and tube II and pipe H to break the vacuum action which would otherwise exist to suck the water out of the flush tank whenthe water supply is cut of! from the nozzle II and water supply pipe l2. v
- The opening and closing d vice for promoting openings Is in the cage so that noiseless operation of the plunger valve comprises a valve operating lever 29 which is pivoted on a pivot pin 30 on the valve body at a point above the projecting end of the plunger valve 2|. The valve operating lever is provided with a downwardly directed arm 3| which contacts with the projecting end of the plunger valve, and is also provided with an outwardly directed arm 32- against the upper side or which the float lever 33 contacts. The valve operating lever and the float lever are mounted on the same pivot pin 30 for movement together or for movement relative to each other.
A latch lever 34, which .may be called the silencing lever, is pivoted at one end on a pivot pin 35 carried by cars 5 disposed on the valve body at a point higher than, and inwardly of, the pivot'pin 30 ot the valve operating lever and the float lever.' The latch is provided on the underneath side with a cam projection 36 and is also provided on the same side as the projection with a downwardly extending flnger 31 adapted to be engaged by the float lever 33.
The valve operating lever 29 is provided with an upwardly extending projection 38 which coacts with the downwardly extending projections 36 of the latch lever'in such manner that the float lever will, during its upwardly movement,
move the projection 36 of the latch lever. out of engagement with the projection 38 of the valveoperating lever, see Figures 2 and 5, the movement being so timed that a small gap 39 will exist between the valve 24 and the valve set 26 for an instant before the float permits the valve to fully close under water pressure thereagalnst, and this gap has been found in practise to positively eliminate the noise or hammering hitherto existing just as the valve is moved to completely closed position.
As best shown in Figure '7 instead of incorporating the vacuum breaking openings in the plunger valve itself a hollow plug 40' may be threaded-into an extension 4| on the water inlet nozzle 42. A hollow plunger valve 43 is mounted to slide endwise in the bore oi the hollow plug and is provided on the inner side with a valve 43, adapted to seat on a beveled seat 44 at one end of the bore of the plug. A nut 45 is threaded onto the other end of the plunger valve and is adapted to-engage a stop shoulder 46 on the adjacent end of the plug to limit opening movement of the valve 43 under vacuum suction thereagainst when the water is cut oi! from the supply nozzle 42. The nut 45 and the plunger valve 43 are provided with respective air supply openings 41 and 48 which permit atmospheric air to rush through the bore of the hollow plunger valve and break the vacuum which would tend to suck out the water from the flush tank when the water supply is cut 01! from the nozzle 42.
Since the operation ofthe parts has been described as the d scription of the parts progressed it is thought the invention will be fully understood without further explanation. I
