To aZZ whom it may concern: 7

Be it known that I, FREDERICK H. BAR- THOLOMEW, of the city, county, and State of.

New York, have invented a new and useful Improvement in \Vater-Closets or Valves therefor; and I do hereby declare that the fol-- lowing is a full,.clear, and exact description of the same, reference being had to the accompanying drawings, making a part of thisspecification, in which Figure 1 is a vertical central section of my invention. Fig. 2 is a view of the under side of the cover of the closet to which my invention is applied. Figs. 3 and 4' are vertical central sections of modifications of my invention; Figs. 5 and 6., detached views of obstructions placed in the waterpasfsage andper; taining to my inve'ntioiL' i i Similar letters of reference indicate corresponding parts in the several figures.

The object of my invention is topro'vide for a water-closet a cock for supplying the water to the closet, which cock shall be closed by the pressure of the water flowing through it, and at the same time regulating or retardingthe closing of the valve so as to insure a proper supply of water to the pan after the haudle is dropped, by combining with itmy variable chamber, while the valve (when having been opened by the force applied to tip the pan) shall remainopen till closed by the force of water flowing through it, and avoid all extraneous forces capable of closing the valve without the action of the water.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

The drawing Fig. 1 illustrates the valvechamber A, having an inlet and an outletbetween which is arranged the valve-opening or valve-seat S, having its valve R and stem D extending longitudinally with the chamber. 7

At one end of the stem, or otherwise within the chamber described, is arranged my gov- ;erning-chamber Z, which is formed by securing an india-rubber diaphragm, H, thereto, and confining the diaphragm by the edge to one end of the valve-chamber by a screw-cap, 0, thus forming a bellows or an expanding and contracting chamber having asmall leak-passage into or out of it, as a drilled hole, M, or anvother contracted passage admitting fluid to pass through, through which leak or hble only can the chamber fill. I providea larger orifice or outlet, L, through which the chamb'cr Z may be rapidly discharged, and provide a valve which will close thelatter discharge when the main discharge or flow of water isto be stopped. the valve, to close the said larger orifice.

Other modifications of valve and lever. for opening, the samcfivariously constructed and arranged. will answer the purpose required.

with a rubber diaphragm properly secured to the stem by nut G, as shown, the stemalso extending through the base-screw or standard not B, for the purpose of affording a means of as here shown. Upon raising the valvefitem, which is done upon lifting the handle of the closet to open the valve,if the water in the supply-pipe shall at the time be shut oh" the valve will remain open till the water is let on, and then the pressure of water while flowing will act water against the first-described diaphragm, H, will tend to hold the valve from closing till 1 Water can enter into the regulating-chamber Z, and thus distend it as the valve is moved toward its seat, while the pressure of the water against the latterdeseribed diaphragm,E, will force or draw the valve gradually to close upon the seat more or less rapidly in propor: tion to the size of the opening M or other leakpassage admitting water into the regulatingchamber Z. The pressure of water in cham ber Z will aid to close the valve. A

- The communications leading either out or into the regnlatingchanibermay be construetother suitable \vay,so as the described purpose is .attainedthatis, to retard the motion of the closing of the valve.

By making the induction or supply way larger than the eduction-way a greater pressure is obtained against the latter-described diaphragm, E, to close the valve, and for this purpose I use a flexible self-adjusting obstruction, A, (see Fig. 5,) placed in the eductionway, so as to secure a proper pressure of water to close the valve, however diminished the supply .of water may be, so'that it is suppliedunder a proper head. This obstruction A I employ a rubber band, K, for

I close the opposite end of the chamber also yenenn s t val h nsprl d t the. c ose against thetwo diaphragms. The action of the ed and arranged as here described, or in any obstruction, B, is shown in Fig. 6, havingslits b made :in it, and so arranged that it may be fitted under the valve-seat surrounding the valve-stem. (SeeFig.1.) The small passage M only into regulating-chamber Z might answer, provided it were not desirable to open the pan of a closet rapidly. The re 'ulating-chaniber Z- may be so provided with its discharge-passage that it shall retard the closing of the main .valve while either distending or discharging, or both.

Various other plans and modi lieatious might.

be employed to embrace what I claim to be ofv my invention and accomplish the purpose described. In Figs. 3 and 4. two modifications are shown. Fig. 3 shows the employment 01' use of pistons G 0', instead of diaphragms, and in Fig. 4 there are two regulating-chambers,

Z Z. The same end, however, is obtained in these as in the original-plan.

Having thus ,deseribedmy invention," what I claim as new, and desire to secure by Letters Patent, isl 1. In combination with a water-closet, a supply-valve, valve-stem, diaphragm E, and regulating-chamber, said parts being so arranged thatthe valve may be opened by the manual force applied to it and closed by the pressure of thewater and retarded in its elosing, substantially in the manner as and for the purpose set forth.

2'. A flexible disk forming an obstruction in v the water passage or way of the cock, to 0p erate in the manner substantially as and for the purpose set forth.
