IMPRQVEMENT IN AUTOMATICALLV-CLEANSING WATER-CLOSETS. A.

Specification forming part of Letters Patent No. 165,174, dated July 6, 1875; application filed D:cember 16, 1874.

Toall whom 'it may concer-n:

Be it known that I, J osErH J. ODoNoHUE, of the city of Baltimore and State of Maryland, have invented certain new and useful Improvements in Automatically-Gleansin g Water-Glosets, of which the following is a'specitication; and I do hereby declare that in the same is contained a full, clear, and exact description of my said invention, reference being had to the accompanying drawing and to the letters of reference marked thereon.

' My invention relates more especially to the valves and attachments by means of which the water is admitted to the bowl for the cleansing of the same, and to a combination of devices by means ot' which the movement of the panA is made dependent upon that of the valves and attachments aforesaid.

In the description of my invention which foly lows due reference must be had to the accompanying drawing forming a part of this specitication, and in which- Figure l is a partially-sectional view of the principal parts of a water-closet embodying my improvements; and Fig. 2, a sectional view of parts of the invention on an enlarged scale.

Similar letters of reference indicate similar parts in both gures.

In the drawing, A represents the bowl of theV water-closet, and-B the trunk upon which the bowl rests. O is the seat, hinged or suspended in-such manner as'to allow of its depression upon weight being applied thereto. D is a valve-case provided-with the inlet and outlet pipes a and b, the inlet-pipe a connecting to the water-supply, and the outlet-pipe b to the bowl A. The valve-case D is divided into two distinct compartments or chambers by the partition c, the upper one, or water-chamber, being at all times filled with water, and the lower one, or connection-chamber, in constant communication with the trunk B. At a point near the top of the water-chamber is secured a perforated valve plate or seat, b', which is connected to the partition o by a tube, d. Immeg diately below the valve-plate is a valve, e, faced with some flexible packing substance, and sustained in place by means of a spiralspring, f, conned between said valve and partition c aforesaid. E is the valve-stem, the upper end of which is forced, by means of a second spiral spring, h, which bears. against a collar, l,upon

said stem, to the under side of the seat C, elev vating the same and opening the valve g, secured to said stem above the valve-plate b. The lower end of valve-stem is connected, by means of a rod, i, to the pan m in such manner as to retain the said pan in a closed position when saidstem is elevated.

Parts of my invention not yet referred to will Y be described and their several uses fully set forth in the description of the operation of a water closet embodying my improvements which follows.

When the water-closet is not in use the parts thereof occupy the positions shown in the drawing, the upper valve, g, being open, and the lower r`one, e, closed, and the pan fm covering the lower end of the bowl; but upon the seat being occupied the Weight `of the occupant causes the depression of the scat and stem E, and consequently the closing of the valve g, attached to said stem. During thisoperatiou the pan m is lowered or opened', and the lower valve e, which is` sustained by the spring f, forced down by means of the rods n, projecting from the upper valve g, attached to valvestem E. The rods n pass through the perforations in the valve-plate b', and to prevent injury to the flexible packing of theI valve c, caused by the action of said rods thereupon, rotation of the said valve may be prevented by some simple attachment to the valve-case. As long as the seat is occupied it is depressed, and the flow of water to the bowl prevented, but upon the seat being relieved of the weight of the occupant it is raised by means of the spring It and stem E, and the valve g being opened b v the elevation of the stem, the water Hows to the bowl, and continues to liow until the valve e closes. The valve e does not close with the opening of the one g, being independent of it and operated upon. only by the spring f, buthas a retarded motion upon the tube consequent upon the friction caused by the set-screw o bearing against the outer surface of said tube. The movement of the stem E and its connecting parts can also be retarded by means of set-screwr1 in the upper end of the valve-case.

The sizes of the different parts of Ithis invention and the tension of the set-screws can be regulated to allow sufficient water to pass to the bowl to cleanse it before the closing of the valve e, and when such arrangement and regnlation are had, the bowl and trap below it are cleansed without any manipulation ofthe parts, and that, too, without an unnecessary expenditure of Water.

Having thus described my invention, what combination with the spiral spring h and valvecase D, substantially as speeitied.

4. The combination ot' the pan m and rod t' with the vertically-moving' valve-stem E, substantially as described. y

5. The valve-case D, divided into separate compartments or chambers, as shown, in combination with the inlet and outlet pipes a and b, and provided with the combination of valves connected and operated as described, substantially as and for the purpose set forth.

In testimony whereof I have hereunto sub.

scribed my name this 14th day of December, in the year of our Lord 1874.
