To all whom it may concern:

Be it known that we, HENRY J. Grossi?. and VILLIAM VAGNER, both citizens of the United States, residing at Reno, in the county of Washoe and State of Nevada, have invented new and useful Improvements in Flushing Apparatus, of which the following is a specification.

This invention relates to flushing appa ratus, and particularly pertains to flushing tanks used in connection with toilets and the like.

It is the object of this invention to provide a simple, practical liushing apparatus, so constructed as not to be liable to get out of order; which is adapted to be connected to a toilet or other fixture in close proximity thereto, and to be discharged under pressure direct from the main source of water supply; and which is exceedingly simple in construction, and positive, eficient and silent in operation.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Figure 1 is a view in vertical section of the invention. Fig. 2 is an enlarged detail of the valves and operating mechanism in their normal position. Fig. 3 is a detail showing the valves in the open or iushing position.

In the drawings, A is a sealed pressure tank or reservoir of any suitable size, shape or material, in which the operating parts of the invention are mounted. Suitably secured to the under side of this tank is the discharge pipe 2 which may be attached at its opposite end to any desired fixture, as a bowl or the like, not necessary here to be shown. Suitably mounted within the head of the pipe 2 at a point adjacent to the tank cylinder A, is a crank-arm or trigger 3 attached to a shaft 4 and adapted to be raised to press against the head of a plunger 5 by means of a hand-lever 6. The plunger 5 slides between guides formed on a spider 7 on the hollow flushing valve 8, which latter normally rests on the seat 9 formed by the upwardly projecting mouth of the discharge pipe 2 within tank A. A suitable cushion or buffer washer 10 is held in position on the seating face of valve 8 by means of a lock nut 11 threaded on the outside of the valve. A stern 12 connected to the plunger 5 extends up through valve 8 and is enlarged, at 13, to form a guide which is longitudinally slotted at 14. This stem 12 13,carries at its upper end a pressure releasing valve 15 which seats, at 16, upon the valve head 8 and is lifted slightly by the action of the trigger 3 in advance of the opening of the larger valve 8.

A guide stem 17, notched at 18, is secured to an upwardly projecting portion 19 of the pressure releasing valve 15 and slides in a bearing 20` formed in the bottom of an inner fiusheregulating tank 21. The bearing 2O and tank 21 are threaded to a valve cage 22 and form the top thereof. The valve cage 22 is threaded to the upwardly projecting seat portion 9 of the pipe 2, and bears against the bottom of the tank A. Openings 23 are provided in the valve cas ing 22 to allow the water to ow freely from the tank A to the discharge pipe 2 when the valve 8 is opened. The tank 21 is open on top and has a perforated bottom, as shown, but these perforations are of limited size so that discharge therethrough takes place slowly, for the purpose shortly to be described.

A float 24 is pivotally mounted on the long arm of a bell crank lever 25 pivoted at 26 to a bearing 27 formed on the bearing 20 with the flush-regulating tank 21. The short arm of the crank lever 25 is pivoted to a sliding bar or latch 28 which is adapted to enter a slot in the bearin 2O and engage the notch 18 in the stem 17 and hold up the valve 8 whenever the latter is lifted by the operating lever 6; assuming, of course, the water in the tanks A and 21 is high enough to buoy up the oat 24. This float, in fact, acts with a yielding pressure normally to press the latch 28 against the stem 17 as long as the Water remains at a sufficient level in tanks A and 21.

In operation, water from any suitable source of supply, as the city mains, under pressure, is admitted to the flushing tank A at 29, in Fig. 1. The water practically fills the tank A and compresses such air as may be therein, up into the upper dome portion 30 of the tank A, which latter we prefer to construct in cylindrical form, as shown in Fig. 1. When the tank A is filled, the valves before described and the floating ball 24 are submerged. The tendency of the ball 24 to rise in the water causes an upward pull on V the lever-arm 25, and thus keeps the sliding contact with Vthe notched stemV 17. The filling of the tank A of course fills the flush-regulating Vtank 21 and submerges the float2l1.V When through the grooves 14 in the piston 13 to relieve the ypressure of water in the tank A,

Y andto a degree equalize the pressure on the two sides of valve A8. Continued pressure by the trigger 3 carries theplunger 5 against the guides 7 and lifts the valve 8 off the seat 9,V thereby allowing the rapid'discharge 'of a Vheavy volume o f Y water under pressure from thetank A into the flushing pipe 2 in the vdirection of the arrows shown in Fig. 3.

Y l The discharge'from tank A throughV open- VVings 23V and around the insideV tank' 21 is much more rapid than is the discharge from tank21 through lthe holes 31 in the bottomV A 0f tank 21.

The upward movement of the stem 17 which is simultaneous with that of the valve 8, bringsV the notch 18 above the slidingflatch' 28, which latter is caused 'to engage the notch 18 by reason ofthe upward pull of the ball 24. The handle 6 may then Ybe released, whereupon the crankarm ,3 falls back toits normal position. 'Ihe sliding latch 28 retains the valve 8 open until' the water in the tank A is discharged, and as tank 21' gradually lempties through the "l holes 31 theiioat 2 4 drops until the latch 28 is withdrawn from thei notch 18 in the stem 17, whereupon valves 8 and 15 drop back to theirV closed 'and-*normal position, and `the,

tank A is again l'rapidly refilled through 'the L. pipe 29. Thisarrangement of'a perforated Y inner tankand cushioned valves gives a .45.

flushing apparatus that is almost silent in operation, and one Vin which a predetermined quantity of water will be discharged 'each f ,i time.
