WASTE-WATER GUARD FOR WATER-CLOSETS.

SPECIFICATION forming part of Letters Patent No. 234,287, dated November 9, 1880.

Application filed April 14, 1880. (No model.) Patented in England October 16, 1878.

.To all tti/tom it may concern:

Be it known that we, GEORGE JENNINGs and GEORGE J ENNINGS, J r., both of Stangate, in the county of Surrey, England, have invented a new and useful Improvement in Water Waste Guards for Water Closets. Sac., which improvement is fully set forth in the following specification, reference being had to the accompanying drawings, in which- Figure 1 represents a vertical central section of a closet embodying our invention. Fig. 2 is a detail view of the piston. 4

Similar letters indicate corresponding parts.

Our invention relates to appliances for controlling the supply or discharge of water in water-closets and other places, its object being to prevent waste; and it consists, mainly, in the combination, with a water-closet bowl, of a well arranged on a level therewith, a valve-seat arranged below the well and at the mouth of a trap arranged to receive the contents of the bowl, a valve to t said seat, a cylinder attached to said valve and extending into the well7 and a piston playing on said cylinder and connected with the pull-handle in such manner that when the cylinder is lled with water it will -rise with the pull-handle and then descend independently thereof, all as more fully hereinafter described and explained.

In the drawings, the letter A designates the pull-handle of a water-closet. This handle is of substantially the usual form on its upper part, where it is guided by an ordinary dish or frame, B, and is provided with a piston, O, at the lower end. This piston is located in a cylinder, D, at one end of which is a stuffingboX, E, through which passes the pull-handle A, the cylinder being also provided with a central stem, a, extending up into the handle, whereby the cylinder and the handle are guided on each other.

The interior of the cylinder D is of less diameter on the lower portion thereof than on its upper part, as shown, and the piston O is litted to the lower part of the cylinder. The piston Gis loose on the handle A, and thelatter is provided with two flanges, b c, (see Fig. 2,) between which the piston is situated, these flanges being so arranged that the piston is capable of a slight movement on the handle.

That part of the handle A between the flanges b c is attened or squared, so that longitudinal spaces or passages d are formed between the piston and handle, and in the top face of the lian ge b are radial channels, one of which is shown at e, Fig. 2, while on the top face of the piston C are lugs f.

Water or other liquid is poured into the cylinder D, and when the handle A is pulled up the pressure of the liquid tends to force the piston C down on the lower ange, b, of the handle, as shown, whereby the lower ends of the spaces d are closed against the passage of liquid through them, and the cylinder is caused to move up with the handle. A small quantity of liquid is allowed to escape from above to below the piston G, when the latter is in its lowest position, by way of the radial channels e, jointly with the passages d and if, when the parts have been lifted, the handle A is held up, either by accident or design, this escape of the liquid allows the cylinder D to sink down slowly until the upper or widest part of the cylinder arrives at the piston, when the cylinder at once drops down onto its support, there being no check to the passage of the liquid.

It will now be understood that while the cylinder D is lifted up together with the handle A, it is permitted to descend independently thereof, and it is obvious that such a result can be attained by other means than the one described-as, for instance, by a proper arrangement of valves in the piston.

If when the cylinder D has dropped down, leaving the handle A in an upper position, the latter is lowered, the piston C is forced up against the flange c of the handle by the pressure of liquid below it, but without closing the passage d, owing to the interposition of the lugs f between the piston and said iiange. It follows that the liquid can pass freely from below to above the piston C, and there is no check to the downward motion of the handle.

The cylinder D is connected with the supply valve or cock of a water-closet in such a manner that this valve is opened in the upward motion ofthe cylinder, and closed when the latter descends, and since the valve is thereby allowed to remain open only a given time, waste of water is prevented. The cylinder D is also connected with the pan-valve or discharge-valve of the closet, so as to open and close this valve simultaneously with the release of the water-supply valve. In this example the dischargevalve is connected or formed directly on the lower end of the cylinder D, as at F, and the seat f of this valve is at the bottom of a well, F', which communicates with the pan G of the closet, and in which the cylinder and pull-handle are situated. The connection of the discharge-valve as well as the supply-valve with the cylinder D, however, may be made through suitable levers, and the cylinder D arranged to rest on the door in thevvicinity of the pan.

When our invention is applied to a closet of the form shown, the cylinder D is constructed with a flange, H, which tits in the well F, and constitutes a shield, preventing the entrance of soil or other matter running out of the pan G to the well.

Our invention is peculiarly' adapted to water-closets; but it may also be used for preventing the discharge of too large a quantity of water at any one time in other places, as also to prevent the escape of had air from soilpipes through what are known as trapless closets, since the valve of the closet cannot remain open, even though its handle be held or propped up.

What we claim as new, and desire to secure by Letters Patent, is

1. The combination, with the bowl G, well F', and valve-seat arranged below said well, of the valve F, cylinder D, attached to said valve, the piston C, playing in said cylinder, and the pull-handle A, connected with said piston, substantially as described.

2. The combination, with the cylinder D, carrying the valve, of the piston having a central opening, the pull-handle A, havin g flanges b c, arranged at a proper distance apart to alternately strike the piston, stops j, and suitable passages to permit Water to ow from the upper to the lower side of the piston, substantially as and for the purpose set forth.

3. A cylinder, D, constructed with the shield H, in combination with the handle A and piston C, all adapted to operate substantially as described.
