FLUSHlNG-TANK FOR WATER-CLOSETS.

SPECIFICATION forming part of Letters Patent No. 565,997, dated August 18, 1896.

Application filed October 7, 1895.

zen of the United States, residing at Toledo, Lucas county, Ohio, have invented certain new and useful Improvements. in Flushing- Tanks for Water-Closets, of which the following is a specification.

In most of the flushing-tanks now in use a noise is produced in the operation of flushing, owingto the slow closing of the valvecontrolling the water-inl'etto the tank, the aperture gradually becoming so small that a longcontinued loud hissing sound is produced, especially when the water supply is under high pressure.

My invention relates to and its object is to provide means for overcoming this objection, and, more particularly, to provide large valve area for the inlet to the tank and mechanism whereby the inlet-valves may be easily and readily operated, and by which they will be closed positively, quickly, and noiselessly when the water reaches a given height within the tank after each flushing operation.

The further object of my invention is to accomplish the above result .by means of mechanism which shall be cheap, durable, and positive in its operation, and which dispenses with the use of the supplemental floats heretofore employed to accomplish this object.

' In the accompanying drawings, made part hereof, Figure 1 represents a central vertical longitudinal sectional elevation of my device; Fig. 2, an enlarged front view of the detents and their tripping mechanism, hereinafter referred to and Fig. 3, a side view of the same.

Like letters of reference indicate like parts throughout the several views.

In the drawings, a is the tank, I) the inletpipe, and c the outlet-pipe. The'inlet and the siphon 0, leading to the outlet-pipe, are controlled by the usual lever d and pull-chain 6. Above and partly within the tank is a chamberf, in which terminates the inlet-pipe b. In the lower part of this chamber are seated two valves 9 and it, having their downwardly projecting stems connected with valve-lever i, which, in turn is connected by chain with the lever d. The lower part of the stems of the valves 9 h are forked, as at g h, the forks being astride of the lever 6 Serial No. 564,829. (No model.)

and the contact part of the fork g being normally nearer to the lever t' than is the corre sponding part of the fork h, so that when the lever is raised by a pull on the chain 6, through lever d and chain is, the valve-stem of valve 9 is first engaged, 'so that this valve is first opened, and the valve-stem h is next on gaged, and the valve It opened, the arrangement being such that the valve 9 is always opened first and closed last. The valve 9 is of smaller area than the valve h, the smaller valve being designed to break the pressure in chamber f, so that the larger valve It may be readily lifted without requiring too much force and Without too much strain'upon the levers and chains.

Secured within the tank is a plate Z, having one of its fiat sides (hereinafter termed the front side) parallel with and near to the lever t', the opposite side of this plate (hereinafter termed the rear side) being parallel with and near to the lever m, which carries at its free extremity float it. The plate Z is slotted through from front to rear side, as at Z. plate near its upper end and swinging in slot Z is a detent 0, having near its lower end a horizontal portion or shoulder 0, from which curves downwardly a finger 0 The lever t' normally rests just below the curved finger 0 and when this lever is pulled upwardly it presses and rubs against the curved finger, forcing the detent 0 into the slot Z until the lever passes to a point above the shoulder 0, when the detent falls into its original position with the shoulder underneath the lever, where the lever is supported and retained until the detent is released by the mechanism now to be explained.

Upon the front side of the plate Z are guides 19, in which slides vertically bar q, having at its lower end eye q, through which passes float-lever m, and having pivoted at and suspended from its upper end, as at g detent r.

Pivoted to the rear side .of the Pivoted to andsuspended from the plate Z,

by means of eyes 3, is a tripping-piece 15, formed, preferably, of heavy stout wire, as are the detents 0 and 1". r This tripping-piece is formed at its upper end with two loops t, which engage the eyes 3 on the plate.

loops t are united by horizontal portion 25 and the two vertical portions i which latter The;.

portions are united near their lower ends by horizontal 'cross-pieces't and t The upper cross-piece or horizontal part t projects outwardly from the front of the plate, as shown in Fig. 3, and is engaged on its lower side by a shoulder-piece r, secured to the lower end of detent r and at about ari'ght angle thereto. The cross-piece or horizontal portion t passes between plate Z and the detent 0, which is bent, as at 0 as shown in Fig. 3, to receive the cross-piece t, which serves as a stop against the outward swing of the detent 0, and actuates this detent, as hereinafter described. The lower cross pi'ece or horizontal portion 25 is designed to come in contact with the detent r at its extreme lower end. To effect this contact, the shoulder-piece r is provided with an angular downward extension r having a spring 1*, secured thereto onthe side next t'o'the cross-piece tithe position of the spring 7- being regulated by means ofset-scre'wvfl passing through the lower end of angular extension-piece r and abutting against the spring.

Assumingthat the tank is filled withwater t'o theline 50, Fig. 1, and that thepartsabove described are assembled asshown in the drawings,the operation of myd'evice isas follows:

The: pull-chain 6 being drawn downwardly,

siphon 'cis-opened in the usual way and the water is rapidly discharged 'from the tank through the siphon. By'the same motion of the-pull-chain eand its lever 01, chain 70, with its attached lever,=is lifted upwardly. This movement of theleve'r 4 first lifts the valve '9, which, being of small area, rises with-but little resistance, and the larger valve h is next engaged and lifted. V This valve, the pressure in the chamber f being broken, also lifts with but little resistance. nowgp'oursthrough valves 9 and h into the tank, 'but not so rapidly, however, as the tank is emptied through the siphon. When the lever 'i is raised by the action of the chains e lc- 'and lever d, it comes in contact with the downwardly and inwardly curved fingenpiece o ofdetent 0 and pushes this detent inwardly, in its slotted aperture, until the lever reaches apoint above the horizon tal shoulder 0 of the d'etent,when the shoulder falls into place under the lever, holding it, with its attach-ed valves 9 and h, stationary in its elevated position for the time being. As the water-line ac is lowered by the discharge of the water through the siphon, the float n, with its lever m, descends, drawing downwith it the sliding bar q, to which is pivotally securedthe detent 'r. The spring r attached to the inclined extension-piece r ,'normally rests against the upper side of cross piece of the tripping-piece t. As the detent r descends with the float n, the inclined spring r sliding upon the cross-piece i forces the lower end of the detent outwar'dly until the shoulder 7" reaches a point below the cross-piece t when the shoulder falls by its gravity beneath the cross-piece F,

The water as shown in Fig. 3. It will be seen that the valve-lever "L is now supported by detent o 0 in elevated position, and that the float-lever m, with its connected detent a", engages the projecting arm 25 t of the tripping mechanism. The water having been discharged from the tank down to line y, Fig. 1, through the siphon in the usual way, the tank begins to refill through the valves 9 and h, the float gradually rising until it reaches the Waterline :0, Fig. 1, lifting with it, through its lever, the vertical bar q, with its detent'r. As the shoulder r pulls upwardly on arm 11 t the cross-piece pulls outwardly upon detent 0, behind which cross-piece 25 passes, until the shoulder 0 is drawnentirely within its recess. At this point the adjustment of the spring 7 is such that the lower cross-piece 75 comes in contact with the spring, throwing the shoulder 0" out of engagement withthe cross-piece t at the same instant thatt'he valve-lever t' is released from the detent 0,

the shoulder 7" now being at a point above the cross-piece t The lever, being released, falls, closing the two valves h .g in quicksu'ccession without shock, .j ar, hissing sound, or other objectionable noise. It is necessary that the adjustment of the sprin gs r 'and r should be such that the disengagement ofthe detent r from the tripping-piece 75 shall be simultaneous with thereleaseand fall of the valve-lever, for the reason that if the valvelever should fall first the float wouldrise no higher and'the detent 0 would be heldininoperative position, so that at the next operation of the flushing mechanism the valvelever't' would find no support from the detent 0. If, on the other hand, detent 'r-werereleased from the tripping-piece-t before the fall of the valve-lever, the detent :0 would not be operated, the valves would be'ret'ained in open position, and the flow of the water would be continuous.

The advantage of thefarrangementiof the air-chamber f and itsvalvesyas shown and described, is that the compressed air prevents undue concussion upon thesudden closing of the valves 9 h, while the two valves of large and small area closing in succession serve somewhat the same purpose, as a cock or spigot which is opened and closed gradually tending to prevent concussion. It will be seen, moreover, that thelarge area of valveopening provided by the two valves allows the escape of water as the chamber is emptied without the hissing sound'wh ich my invention is designed to obviate. 7
