WATER-CLOSET VALVE.

SPECIFICA'IGN forming part of Letters Patent No. 274,628, dated March 27, 1883,

Application tiled April 4, 1882.

To all whom it may concern Be it known that I, JOHN McGUIaE,of-1\iil waukee, in the county of Milwaukee, and in the State of Wisconsin, have invented certain new and useful Improvements in (Jocks and Valves for WaterClosets, etc.; and I do hercby declare that the following is a full, clear,

and exact description thereof.

My invention relates to valves for waterclosets and draw-cocks, and will be fully described hereinafter.

In the drawings, Figure'l is a side view ot' my improved water-closet valve. Fig. 2 is a vertical longitudinalsection through the centerthereof, on the line y y, Fig. 3, showing the valve open. Fig( 3 is a transverse section taken on the line aux, Fig. l. Fighe shows my improved valve applied to 'draw-cocks. Fig. 5 is a perspective view of the valve proper, and Fig. 6 is a side view of m v device and the operating-levers of a water-closet.

A is the casting that forms the valve-chamber, and B is the valve. O is the service-pipe, and D the delivery-pipe. E is a chamber, having an opening, a, that leads into the valve B, and another, c', that leads into the chamber back of the valve-head. F is a cog-segment by which the valve is worked, its shaft F extending into a bearing, d, on one side and out through a smiling-box, Gr, on the other, and having a flange, g2, vwhich bears against said box. This box has tapering sides and fits in a collar, g, that has a correspondingly-tapered Inside of the box I place a suitable bushing, h, and over the collar g, I tit a cap, H, that has an interior rim, g', that fits into the cap about the shaft, a bushing, h', being also interposed between this rim g and the outer rim of the cap. v

The interior of myvalve B is open, so as to admit the water from the service through it, and its rear end has one or more concaves, c, to admit the water to the cup-leather valve c',

which allows water to rush past it when the valve is opened, but will not allow it to flow back, and it can get out only through the aperture c; and to regulate its ow I screw a plug, e, into the chamber, and this plug has a hole, e', entering its side at right angles to it, and joining aneth er, c2, that enters its end, and the rapidity of this flow can be regulated by (No model.)

make its aperture either full or partly open to the Vaperture af, the said plug c being screwthreaded on its exterior, so as to enable it to be readily turned either way, whereby its transverse hole e' (which, as stated, communicates with its longitudinal hole e2, leading into the chamber E below the the valve-chamber) may either wholly or partially coincide with the described aperture a. and hence regulate at. any time the amount ot water passing from the rear ot the valve-chamber through these pas sages a', e', and e2 into the chamber E, whence the water tindsits outlet from chamber E back into the valve through aperture a.

`The shaft F has keyed to its outer end a weighted arm, F2, and by it is turned when it is beingopened and closed; and when my valve is being used for water-closets I provide the weighted lever F2 with a short arm,f, that projects in front of its shaft F and carries a wheel,

j, and I provide the water-closet handle k with a lever, k', that has also a wheel, j', in its free arm, and this wheel is arranged to rest upon the wheel j, so that when the handle is pulled up it will depress the free arm of the lever and cause it in turn to depress the short arm f of the lever F2, and, overcoming the weight W, turn the shaft F and open the valve. Then as soon as the levers have been released the weight W, aided bythe head of water in the main, will begin to turn shaft F back and close the valve as it expels the water from the rear ofthe valve-head into chamber E through aperture a' and plug E. When shaft F is in place in the casting it passes through the stuffing-box G, which, resting upon its collar g2,

them, this opposing pressure being capable of regulation to determine the length of time each valve shall permit the water to flow through it.

VThe operation of my valve is as follows: The opening of the valve is 'accomplished by 1ifting the weighted arm of lever F2, (which is done, in the form of valve shown in Fig. 6, by

pulling up the handle 1:,which in turn, through pivoted lever la and wheel j', bears upon the wheel j and depresses the free end of this lever F2, as already described,) and this upward movement of the Weighted arm of said lever revolves the shaft F partially and causes the cog-segment F on said shaft to take into the rack ony the lower portion of theinterior of the valve Band open it against the pressure of the Water in pipe C, as shown in Fig. 2. The

' water will thenrush through past the-valvehead and through the valvel into the deliverypipe D, While a small quantity forces itself.

past the cup-valve c' into the chamber beyond it. Now, when the Weighted arm ofthe lever F2 is released, it will begin to fall, and, aided by the. pressure of water in pipe C, will .close the valve against the pressure of the Waterin the chamber behind the valve, Which must be expelled through aperture a and passage e e2 in screw-plug e into chamber E before the valve can close, the said Water finding its Way back to the valve through the aperture a, as hereinbefore fully described.

What I claim as my invention, and desire to' secure by Letters Patent, is-

1. The valve-casting having seat d and tapering collarg, the tapering box Gr,having packing h and h', and screw cap H, having interior rim, g', in combination with the shaft 1*",extending from the seat d entirely through the valve-chamber, box, and screw-cap, and having ange g2 bearing against the end of box G, all substantially as set forth.

2. In 'combination with shaft F', the weighted lever F2, carrying a wheel on its short arm, and the Water-closet lever havinga Wheel on its arm adjacent to the short arm of lever F2, as set forth.

3. In combination with the valve-casting A, having longitudinal valve-chamber, and the chambered and apertured castingE andits perforated screwplug e, all communicating therewith, the valve B, having eoncaves e, and cupleather valve c', substantially as shown and described, and for the purposeset forth.

4. In combination with lthe casting A, having longitudinal valve-chamber, the valve B, fitting snugly within the valve-chamber, and having an interior rack and concaves c to permit free Water-passage, and the oog-segment F and shaft F', independent tapered box G, and screweap, through which said shaft passes, and suitable packing, all substantially as set forth. g

In testimony that I claim the foregoing I have hereunto set my hand, on this 20th day of March, 1882, in the Vpresence of two witnesses.
