IMPROVEMENT IN WATER-CLOSET VALVES.

Specification forming part of Letters Patent No. 175,035, dated March 21, 1876; application filed February 26, 1876.

To all whom, it may concern :

Be it known that I, Thomas Conaughton, of New York, in the county of New York and State of New York, have invented a new and valuable Improvement in Water-Closet Valyes; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figures 1 and 2 of the drawings are representations of vertical central sections of my valve.

This invention has relation to valves which are designed for water-closets, but which are applicable to other purposes; and the nature of my invention consists in the combination, with a spherical shell, having inlet and outlet passages for water and air, and a push-stem, of an elastic ball, which is hollow, and which is perforated just below the airvalve, as will be hereinafter explained.

The invention also consists in a hollow spherical float in combination with a perforated spherical valve and a spherical shell having an air-vent at its upper part, said float being inside of the valve, and intended to shut the air-vent should the valve burst, as will be understood from the followingdescription :

The metal case of my improved valve is spherical and composed of. two parts, A A', screwed together, as shown in Fig. 2. The bottom section A is constructed with a screwthreaded inlet-pipe, a, and a screw-threaded outlet-pipe, a'; also, with a standard, &amp;, which is screw-threaded and adapted to receive a valve, c, the stem c' of which may be any desired length.

The upper section A' of the case is perforated at d, which perforation is surrounded externally by a prismatic valve-box, 0, perfo- , rated at several points, and having screwed upon it a removable cap, e, constructed with a nut head to receive a wrench, and a stud,/, on its under side, which is loosely inserted into a hole made in the stem of a valve, D, which closes the opening d. This valve D has a very fine perforation, i, through it, which admits air into a spherical valve, E, when the valve D is shut.

Valve E is a hollow sphere made of indiarubber, and preferably constructed with a packing-flange,/ which seals the joint between the sections A A' of the case. At the highest part of the valve E is an opening, d', which registers with the opening d through the case, and which is designed for the exit and admission of air.

Inside of the valve E is a hollow spherical float, G, which will rise and shut the openings d d! should the valve E burst.

When the stem c' of valve c is forced up, as shown in Fig. 1, a passage will be opened through the valve-case for water, and when the stem c' is released the pipes a a' will be shut by the expansion of the valve E.
