WILLIAM J. HEARN, OF NEW YORK N. Y.

WATER-CLOSET VALVE.

GPECIFICATION forming part of Letters Patent No. 303,846, dated August 19, 1884.

Application filed January 7, 1884.

To all whom it may concern.-

Be it known that I, XVILLIAM J. IXEARN, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in XVater-Closet Valves, vof which the following is a specification.

This invention relates to a valve and overflow, the valve being so constructed that it opens automatically whenever the water in the basin rises beyondthc desired level. The peculiar and novel construction of my valve is pointed out in the following specification, and illustrated in the accompanying drawings, in which Figure 1 represents a vertical central section in the plane a; a, Fig. 2 Fig. 2 is a hori zon'tal section in the plane 3 y, Fig. 1.

Similar letters indicate corrcspondin g parts.

In the drawings, the letter A designates the basin, of a water-closet, which communicates by a channel, 13, with the valve-chamber (J. D is the valve, which is seated on the mouth of the waste-pipe E. The stem a of the valve is hollow, and on its upper end is secured acylindrical jacket, 0, which is closed at the top and open at the bottom. From this jacket extend a series of arms, 0, which support a cup, (I, provided with a center discharge, c. The arms 0 extend upward in a vertical direction, and they fit a cylinder, f, which is secured in the top of the valvechambcr (l, and which is open at the bottom and closed at the top. The upper part of the cylinder-f forms an air-chambcr,' 1 which communicates through the center discharge, 0, and through the hollow valve-stem a, with the wastepipc \Vhcn the basin is empty, the valve rests upon its seat, and it remains in this position as long as the water in the bar sin does not rise above the level indicated in Fig. 1. But whenever the water in the basin rises above this level, it ilows over the top of the jacket I), and through the hollow stein a, into the waste pipe E. current of water a suction is produced through center discharge, a, of the cup (I, the air in the air-chamber 9 becomes rarefied, and in a short time the valve rises from its seat, and the matter contained in the basin discharges.

By this dow n ward.

(No model.)

Various means may be employed for introducing into the basin a snflicient quantity of water to cause the valve to rise, and in the example illustrated by the drawings I have shown a chamber, F, which connects with the lower part of the valve-chamber O, and which contains a float, G, that connects by a cord or chain, h, with a lever serving to open and to close the water-supply valve. This valve may be situated in a tank connecting with the basin A by the supplypipe i, or the watersupply valve may be arranged in any other of the well known ways usually employed in water-closets. After having used the closet it is only necessary to pull the chain 7i for a short space of time, and by these means a suilicient supply of wa ter is caused to flow into the basin, so that a.

violent overflow is created, and by the current of water rushing down through the hollow valve-stem a the air in the air-chamber is immediately rarefied to such a degree that the valve 1) rises, and the contents of the basin, together with the water contained in the valve-chamber C and in the float-chamber F, are free to discharge. By the weight of the float the water-supply valve is held open until the water in the basin has risen to the desired level, and since the float is buoyed up by the water the water-supply valve closes as soon as the water in the basin has reached the desired level.

That I claim as new, and desire to secure by Letters Patent, is-

1. The combination, substantially as hereinbefore described, 01' the basin, the valvechambcr, which communicates with said basin, the waste-pipe, the valve,which is seated on the mouth of the wastepipc, the hollow 3. The combination, substantially as here- In testimony whereof Ihavehereunto set my inbefore described, of the valve the valvehand and seal in the presence of two subscribehmnber, the hollow valve-stem, the cylinder ing Witnesses; it I r secured in the top of the valve-chamber, the XVILLIAM J. HEARN. [L s.]

air-chamber formed in the upper part of the Witnesses: cylinder, the cup secured 011 the valve-stem, \V. HAUFF, and the center discharge in the cup. E. F. KASTENH'UBER.
