BALL COCK 1 R FLUSH TANKS.
Specification of Letters Patent.
Fat-rented Feb. 28, 1922.
Application filed November 9, 1920. Serial No. 422,790.
To allwlwmit mag concern v Be it known that I, Crmunrs r1. GUNN, a citizen of the United States, residing at Oak- 'land, county of Alameda, State of-California, have invented certain new and useful Improvements in Ball Cocks for Flush Tanks; and I do declare the following to be a full, clear, and exact description of the same, reference being hadto the accompanying drawings, and to the characters of ref: erence marked thereon, which form apart of this application. l
This invention relates to improvements in the ball or float actuated valves or cocks commonly used in toilet flush tanks. The principal object of the invention is to devise a valve of this type which it is possible to make much cheaper than those now employed and yet which will have a more positively seating valve-member than these oth ers. This cheapness of construction is obtained, not by cheapmaterials or sacrificing strength in any way, but by the fact that machining such as boring, finishing and the like is reducedto a minimum. In fact there is only one part which need be finished, and thatis the seat for the valve. I
Another object is to provide a means for regulating the valve member relative to its seat, and Without detaching the device from the tank. In this manner the valve may be adjusted to always fit its seat regardless of any wear, and with an unchanged arc of movement of the ball float. This obviates the annoyance had with the present style of valve when the same fails to seat, as is quite frequent even when the tank is full; resulting in a constant overflow and trickle of water into the toilet bowl which is impossible to stop without completely shutting the exterior valve of the supply pipe, and replacing the worn rubber valve member with a new one.
These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.
In the drawings, similar characters of reference indicate corresponding parts in the,
several views.
Fig. 1 is a side elevation of my improved valve.
Fig. 2 is a sectional view of the same.
Fig. 3 is a cross section on a line 33 of Fig. 1.
Fig. i is a top plan view of the valve.
Referring now more particularly to the eharacters of reference marked on the drawings, the numeral 1 denotes the main body of the valve, preferably a U-sha'ped tubular member, one arm of which is longer than the other and is provided adjacent its lower end with a flange 2 and with a threaded portion 3 therebelow to adapt itfor connection to a tank and to the source of supply in the usual manner. 7
Some distance from the other end of the body 1 an upwardly-tapering valve seat 4 is formed, below which isa slot, 5 cut through the body 1 and terminating in a threaded boss 6, to which a pipe may be-coupledand extended to the lowest point of the tank, so that there will be no noise of falling water.
Adapted to take into the seat ,4, isarubber plunger 7, tapered on its upper end as at 8 to the same degree as the seat hand encased in a metal sleeve9 loosely fitting in the body 1 and projecting below the end of the same into a cup 10. This cup rests on the cross arm 11 connecting a pair of bars or straps 12 which project upwardly between guides 13 on bothsides of the body 1 and above-the same, being there pivoted to a U-shaped lever arm 1% which in turn, is pivoted at-a point off set a suitable distance from the strap connections as at 15 to a lug 16 projecting upwardly and formed with the body.
To the opposite end of the member 1a is adjustably connected as at 17 the float rod or arm 18, such adjustable arrangement being common practice. 7
I have here shown the lug 16 as being relatively short so that the member 15 rests practically on top of the body.
it is evident however that should it be desired to use this device in a deep tank, the lug 16, and also of course the straps 12 could be lengthened to suit without changing the operation of the valve in the slightest degree.
The operation of the valve it is thought, will be self evident. On account of the offset connections of the straps and lug with the lever arm, the movement of the latter, which'is governed by the changing of level of the water on which the ball floats, will cause the plunger 7 to be raised and to seat when the water level attains a certain and predetermined height, which in itself is governed by adjusting the connection 17 When the plunger 7 however is worn, it will no longer seat properly, and in order to cause the same to reseat without renewing the rubber plunger or adjusting the float so as to admit more water and allow the plunger greater niovei'nent, I provide an adjustable screw 19 through the cross arm 11 of the straps which bears on the under side of the cup 10, forcing the same upwardly away from the said arm without disturbing the lever connections, or dismounting any part ofthe device, since this screw is accessible and may be turned by means of a small wrench or pair of pliers.
I do not'believe it will be necessary to connect the cup with the straps in any way, since neither can have any lateral movement, the straps being held in alinement by the guides 13 and the cup by reason of the fact that the sleeve 9 of the plunger is always in the body 1 to a certain extent.
From the foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects 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 and do notform a departure from the spirit of the invention as defined by'th'e appended claims.
Having thus described my invention, what I claim as new and usefuland desire to secure by Letters Patent is:
1. A valve of the class described comprising a body member adapted at one end for connection to a source of supply, a tapered valve seat in the opposite end, a tapered plunger adapted to fit into said seat and projecting beyond that end of the body,
straps extending from the plungeron both sides of the body, said straps having a crossarm on which the plungerrests, fioat-actw ated lever means'for'moving'the straps to cause the plunger to move to and from its seat, and an adjustable screw through said cross arm bearing on the adjacent face of the plunger.
3. A valve of the character described comprising an inverted U-shaped body member adapted at one end for connection to a source of supply, a tapered seat a predetermined distance from the other end, a similarl Y tapered plunger adapted to fit in said seat slidable in the body and projectin therefrom, a pair of straps extendin in t e same direction as said plunger on t e outside of the body to a point thereabove, guides on the body for said straps, a connecting arm for the straps passing under the plunger and on which the latter rests, and float actuated lever means connected to the opposite ends of the straps and to the body;
In testimony whereof I affix my signature.
