SPECIFICATION forming part of Letters Patent No. 752,906, dated-February 23, 1904.

' Application l'lled March 21, 1903,

To all w/wm 5 may concern:

Beit known that I, JAMES W. KELLY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois,have invented a new and usefulr Improvement in Water-Closets, `of which the following is a specification.

My invention relates particularly to selfiiushing water-closets; and my primary object is to provide a closet of this character of improved general construction, particular attention being paid to securing simplicity of structure, certainty of operation, freedom from danger of freezing, and freedom from liability to get out of repair. In this construction the tank is located beneath `the lloor-line and suitably drained to prevent freezing. W'hen the seat of the closet is depressed, 'water is admitted to the tank, compressing the air therein, and when Vthe pressure upon theseat is removed the air furnishes the pressure for flushing the closet.

The invention is illustrated in its preferred embodiment inthe accompanying drawings, in whichy Figure 1 represent-sa side 'view' of the closet; and Fig. 2, a broken vertical sectional view of the tank, Hush-pipe, and valve mechanism.

A description of the preferred construction follows. A

' A represents a closet-bowl provided at its rear upper portion withv a combination pipe connection and bracket A; A2, a soil-pipe or soil-pipe connection provided at its lower end with a trap A3; B,'a tank located beneath the lloor B; B2, a Hush-pipe extending throughthe tank and joined ,at its upper end to the connection A; B3, a connection at the lower end of the tank, forming virtually an eXtension of the pipe B2; B4, a water-supply pipe communicating with the connection B3; B5, a drain-pipe connecting the member B3 and the portion with valves C, C2, and C3 and having a projecting upper end equipped with a head C4, Vbetween which and the connection is confined la spring C5, and D a seat having its frontportion resting normally onf the front portion ofthe bowl and'provided at its rear portion with a lhinge D', one leaf of which Serial No. 148,855. (No medal.)

bears upon the upper I' end :of fthe valve-stem or plunger-rod and has its rear end joined by,

a pivote to the member A. I Y

The bowl A may be of any suitableconstruction. The connection A is really a T- shaped, pipe-section, with a bracket on the outer side ofthe vertical portion or cross of the T. The vertical channel of the T is capped by a suitable perforated cap or gland e, through which 4the valve-stem passes. The tank B is provided at its upper end with a central opening for the pipe B2, the latter being externally threaded adjacent-to' theopening to receive a nut 5. The pipe B2] is provided near 'its lower end withV perforations 5", communicating with the tank, and at a short distance above the same with two series of perforations 52 53, separated by an imperforate portion 54.v The perforations Z22-communicate with the perforations 53 through an annular ,passage or by-pass 55, formed by an enlargement 55 on the pipe.y The member B3 comprises a tubular member 57, flanged at its 1 upper end and having liquid-tight connection f thereat with the lower Vend of 'the tank B, an

externally-threaded nipple 58 at one side there- `of for attachment with the pipe Bi, a longitudinal enlargement?) having a channel 51, f constituting a ley-pass from thev tank to the lower Vend of the tubular portion, andY a bottom cap 5u, having an externally -threaded stem connected with the pipe B5. 'Ihe member B3 has its upper end enlarged at its inner diameter and threaded thereat to receive the lower end of the pipe B2.' Gaskets 512.513 serve to make liquid-tight joints, the tank being, as it were, clamped between the nut 5 and the flange of the member Bi. f Y

The valve-stem C is preferably constructed of thread-connected sections for convenience in applying the valves. Near the upper end is a collar c, which normally bears against a gasket c at'the under side of the gland c. The inner diameters of the pipe B2 and member B3 are equal, as are the diameters of all the valves. In the normal position of the closet the valves are located 'as Aindicated in f IOO the valve-stem is depressed the valves occupy the position indicated by the dotted lines, in which position communication with the bowl is cut off and communication between the admission-pipe and tank established.

The seat serves to depress the valves to per-l mit the tank to receive a charge of water and the airin the tank to become compressed by the pressure from the hydrant. When the seat is relieved of its pressure, the valves are raised by the spring C5, disconnecting the tank from the hydrant, establishing connection between the tank and bow-l, and reopening the drain-passage 61, the lower end of which has in the meantime been closed by the valve C. The height to which the tank will become lled will of course depend upon the pressure at the hydrant. The dotted line d represents the water-level under a certain pressure. After the tank has become so nearly empty that the air-pressure no longer will serve to force the water through the bowl the tank and the pipe B2 will drain through the pipe B5.

In addition to its function in depressing the valve-stem the hinge D permits the seat to be thrown back, swinging upon the pintle of the hinge to the inclined position indicated by dotted lines, in which position it is free from danger of falling. An advantage incident to the construction is that the bowl may be placed close to a wall, and, moreover, it is unnecessary to inclose the front portion of the bow Other advantages incident to the general construction will readily appear to those skilled in the art. For instance, the feature of locating the valves within the pipe B2 obviates the necessity of having a pit for a valve located outside. When the valves are in the position indicated by the full lines, the pressure upon the lower surface of the valve C2 is balanced by the pressure on the upper surface of valve C', and when the valves'are in the position indicated by dotted lines the same thing is true, and in addition to this the pressure upon the upper surface of the valve C2 is balanced by the pressure upon the lower surface of the valve C3. The valves are perfectly balanced, therefore, so that the valve-stem is readily depressed and is readily raised by the spring C5. The valves may be removed for repair by unscrewing the gland a and withdrawing the valve-stem from above. Other advantages appertain to the construction, which will be understood by those skilled in the art.

It readily will be understood that changes in details of construction within the spirit of my invention may be made. Hence no undue limitation is to be understood from the foregoing detailed description,the same having been given for clearness of understanding on y.
