FLUSH-VALVE.

. Specification of Letters Patent.

` Patented Mar. 28, 1916.

Application filed July 15, 1915. Serial No. 40,042.

To all whom it may concern:

Be it known that I, 'Ln ROY WILLOUR, a citizen of the United States, residing at Ashland, in the county of Ashland and State of Ohio, have invented certain new and useful Improvements in Flush-Valves, of which the following is a specification.

`My invention relates to'irnprovements in flushing apparatus for use in connection withV toilet bowls, while not necessarily restricted to such use. 1 A

` Animportant object of the invention is to provide means of the above mentioned character, having its operation.

r A further object of the invention is -to the following description.` y y,

. In the accompanying ,drawings forming a part of this speciii'cation and in which like Vnumerals are employed "to Adesignate, `like parts throughout thesame, Figure v1 is a side elevation of apparatus ,embodyingV my invention, showing the same inuse, Fig. 2 `is element or tray.; Y

a central vertical longitudinal sectional view through thevalve easing, associated elements being shown in elevation, Fig. 3 is a transverse vertical sectional viewtakenon line 3--3 of F ig.V 2,`Fig. 4 is ahorizontal sectional view taken on line 1-4 `of Fig. 2, and, Fig. 5 is a plan view of a water impinging In the drawings, wherein forV the purpose i i of illustration is shown a preferred embodiment of my invention, the numeral 10 designates a toilet bowl of any well known or preferred type.

The numeralll` designates a `.preferably Y horizontally arranged casing or shell embodied in a valve structure. This casing is provided near one end with a depending outlet piperor tube`12,vwhich is connected with the bowl 10, and discharges therein. Connected with the upper portion of the casing 11, near its opposite end,is a tubularextension or pipe 13, connected with a Vpressure water holding tank 14, by a coupling 15, of any well known or preferred type. This tank 14 is preferably-provided'with an in-` Wardly opening air supply check valve 14', 0f any well known or preferred type, the

no iioat means for controlling` function of which is to prevent the air 'from being exhausted from the tank 14; during its operation. While I prefer to employ this valve, yet I have found that the apparatus will operate with some degree of success e ment -with a main vertically movablevalve 18 tocover and uncover the intake end of the pipe 12. This vertically movable main valve, as more clearly shown in Fig.,A 3, is provided with vertical apertured knuckles 19, between which is arranged an apertured knuckle 20, these knuckles being pivotally connected by a pin 21, as shown. Connected with the knuckle 20 and preferably `formed integral therewith is an upstanding loop or apertured .element 22, for a purpose to be described.` The-loop 22 has a guide member 23 rigidly connected and preferably formed integral therewith, suchguide member operating in a vertical opening 24:, formed in a removable cap 25, having screw-threaded engagement with the upper end of the casing 11. As more clearly shown in Fig. 3, the y a valve seat for a pressure relief valve 27,

vertically movable with relation to the main valve. The pressure relief valve 28, when unseated, contacts with the knuckle 20 and through it, elevates the main valve 18.

Disposed within rthe pipe ,or tube 12 beneath the depending portions 28 of the valve 27 is a vertically swinging cam element 29, rigidly mounted upon a rock-shaft 30. This rock shaft is journaled throughopenings in the pipe 12 and is horizontally arranged. The rock-shaft v30 extends outwardly beyond the pipe 12 and has a crank 31 rigidly connectedtherewith. Pivotally connected with the outer end of the crank 31 is a link 32, pivotally connected with one end of a vertically swinging lever 33, which is pivotally supported at 34:. The lever 33 is bent outwardly suitably so that Sit does not contact with the bowl 10 when swung upwardly.

Arranged within the body portion of the casingl 10 is avnormally substantially horizontal vertically swinging lever 35, apertimed all .36 for receiving a stationary pivot element 37, attached to the casing 11 by any suitable means. Adjacent its pivot the 1ever 36 is provided with a crank 38, extending within the loop 22, as shown. Connected with the opposite or free end of the lever 35 and preferably formed integral therewith is a water impinging element or tray 39, preferably arranged at a slight angle thereto. rl`he tray 39 is arranged directly beneath the discharge end of the pipe 13, whereby the water flowing through this pipe will` directly impinge upon the tray 39 and move it downwardly. The tray 39 is preferably provided with apertures 40. The main valve 18 and pressure relief valve 27 and associated elements are substantially heavier than the tray 39 and the long arm of the lever 35, whereby, in the absence of the water impinging against the tray 39, the tray will be held in the elevated position.

As more clearly shown in Fig. 3, the end of the casing 11 adjacent the tray 39 is preferably foimed open and covered by a removable plug 41, havingscrew-threaded engagement therewith. p

In the operation of the apparatus, with the main valve 18 and pressure relief valve 27 closed, the water passes through the pipe 16 and of course first fills the casing 11. This water then backs up through the pipe 13 into thepressure casing or shell, entrapping air, which is compressed in the top-:of the casing 14. When the operator swings the lever 33 upwardly, the cam 29 is turned upwardly with the shaft 30, and contacts with the lower end of the extension 28 of the pressure relief valve 27. The water' begins to pass through the opening 26, which breaks the pressure and permits of the easy opening of the main valve 18, upon the fur ther vertical movement of the pressure* relief valve 27, suoli pressure relief valve contacting with the knuckle 20, `to elevate the valve 18. Vhen this valve 18 is elevated or unseated the water drops or rushes downwardly through the pipe 13 and impinges -upon the tray or element 39, thus retaining it in the lowered position during the empty ing of the casing 14. The tray 39 holds the lever 35 in the lowered position, which in turn retains the valve 18 open. Vhen all or practically all of the water has discharged from the casing 14, the main' valve 18 and pressure relief valve 27 automatically gravitate to the lower orclosed positionyswing ing the tray 39 upwardly to the normal raised position. The water is again fed through the pipe 16 into the casing 11, and subsequently into the pressure storage tank 14. Y

It is to be understood that the formof' my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

-Having thus described the invention, 'I claim:

1. The combination with a casing, of a main valve to control the discharge of wa ter from the casing andprovided with up 'standing knuckles, apressure relief valve carried by the main valve, an inner knuckle arranged betweenthe first named knuckles and pivotally connected therewith and adapted to contact'witli theA pressure relief valve upon its upward movement, a member arranged beneathY the pressure reliefvalve `to elevate it, water inlet mea-ns connected with the'casing, and a vertically swinging lever arranged within the casing and having one end connected with the inner knuckle and its opposite endprovided with atray disposed beneath the water inlet means.

2. The combination with a casing provided,` near one end with an approximately vertical` water inlet pipe and near its opposite yend witha depending outlet pipe,` an upwardly opening valve for controlling the passageof water through the outlet pipe,

`means to raise thevalve, a vertically! swinging lever pivotally mountedwithin the cas ing andhaving operative connection with the valve, and a tray rigidly connected with the free end of the vertically swinging lever upstanding shank connected with' the valve and' provided with an elongated opening,a vertically swinging lever pivfotaily mounted within the casing and provided near its pivot with a crank extending Vinto the elongated opening of the shank, a tray rigidly connected with the free end of thelever and arranged rbeneath and adjacentl the inlet pipewhereby the incoming water impinges upon it," and means toraise the valve. to open it.

In testimony whereof I affix my signature in presence of two' witnesses.
