To @ZZ whom t may concern:

Be it known that I, JOHN KIRBY, Jr., a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Vater-Olosets; and I do hereby declare that the following is a clear, full, and exact description of the invention.

My invention relates to valves for water- Io closets and mechanism for operating the same.

The object of the invention is to provide a simple, inexpensive, and efficient spring-retracting valve and mechanism attached to the seat or lid of the closet for operating the same, whereby water communication with the closet will be established by movement of the seat or lid thereof; and it consists in certain novel features of construction and arrangezo ment of parts, as hereinafter fully described, pointed out in the claims at the end of this specication, and shown in the accompanying drawings, which form a part hereof, and in which- Figure l is a rear perspective View of the closet, a portion of the hopper being broken away to show the bowl; Fig. 2, a side view of the valve and its opening mechanism, showing a portion of the hopper in section through 3o the iiushing-inlet and coupling, also showing in cross-section through the center line of the valve the supports at the rear of the hopper and portions of the seat and lid hinged to the same, the seat being shown by solid lines in a semi-elevated position during its upward movement and the valve-stem depressed, and by dotted lines in raised and lowered positions with the valve-stem released; Fig. 3, a vertical sectional View 4o through the center of the valve and its supporting-bracket, the upper part of the valvestem and its curved cross-arm being shown in full, Fig. 4, a vertical sectional view through the center of the valve and connecting-necks looking toward the rear, the upper part of the valve-stem and its curved cross-arm being shown in full; Fig a section through line X X of Fig. 4 looking down; Fig. 6, a perspective view of the valve-operating arm 5o detached from the lid; Fig. 7, a plan view of the same, and Fig. S a side view thereof with the forward sideV of the arm broken away.

Similar letters and numerals of reference indicate corresponding parts throughout all the figures.

My invention is especially applicable to water-closets designed more particularly for use in railway-cars and other places where the supply of water for flushing the closet is carried in tanks, thereby necessitating econ- 6o omy in the use thereof; but it is not limited to any particular source of Water-supply, and it is equally applicable to closets provided with dumping service-pans-such, for example, as is shown and described in United States Letters Patent No. 596,070-such closets being usually provided with a seat mounted above the hopper and a lid mounted above the seat. l have shown and will describe herein my invention applied to such con- 7o struction.

In the accompanying drawings, A represents the hopper, provided with the usual inner bowl a and a flange b, by which flange the hoppermay be secured to the ioor. A flushing-chamber c extend arounds the hopper and is provided with a series of perforations d, through which water passes from the chamber to the interior of the hopper and iiushes the same. Communicating with this 8o chamber there is a water-inlet e, having one end of a screw-threaded hollow sleeve B secured therein and by means of which the valve is connected with the hopper in the usual manner. Above the hopper and resting on its top there is a seat O, hinged to a supporting-shelf D, which is cut away to accommodate the operating mechanism, as shown. Above the seat there is a lid E, hinged to a supporting-shelf F, located im- 9o mediately over the shelf D and recessed, as shown at f, to receive the operating mechanism. It is evident, however, that by using suitably-constructed hinges the lid maybe hinged to the shelf D, in which case the shelf F may be dispensed with; also, that D and'F may be formed of a single piece, if desired, although I prefer the construction shown, and in which construction it will be observed that the operating mechanism and valve are roo obscured from view. The supports D and F may be secured to the hopper by brackets (not shown) or otherwise, or they may be secured to a wall or partition or other part of the car or other structure in which the closet is located. G is the valve-casing, open atiitslowcr end and having a bracket g and strengthening-ribs h and which is also provided with a plate t', by which the casing is secured to the under side of the shelf D. The valve-casin g is also provided with hollow connecting-necks j and k, neck j being coupled to a supply-pipe H, leading from a suitable source of water-supply and coupled to the valve by a union-couplin g I in the usual m anner. The neck c'of the valve-casing and the neck B are connected by means o f an elbow J, (preferably rubber,) having a liange Z at each end, as shown at one end in Fig. 2, and

coupling-nuts K and L.

As the means for connecting the valve with the water-supply and hopper form no part of my invention, I will not further describe the same.

As shown in Figs. 3 and 4, the interior of the valve-casin g is divided into two compartments consisting of an inlet-chamber m and an outlet-chamber n, the separation being formed by a transverse partition o and an inclined partition p, whereby passage-way q is formed and through which water from the supply-pipe H can enter the chamber m, as indicated by the arrow l. The partition o is provided with an opening o' and an annular downwardly-projecting flange s, forming a seat for a valve M, having downwardly and npwardly'projecting stems t and u, joined together, as shown, for convenience in manufacturin g. The lower end of the valve-Casin g is closed by acap u", having a downwardlyprojecting bored shank w, closed at the bottom and containing a spiral spring ai, one end of which rests on the bottom of said shank and the other end having a bearing against the lower end of the valve-stem t, which is movable in the bore of said shank and is guided thereby. In the top of the valvecasing there is formed a downwardly-projecting interior screw-threaded neck y, through thebottom of which the upper stem u of the valve passes,and an interiorly-scre w-threaded packing-nut 2 surrounds the said stem u and engages the thread of the neck y, thus forming a stuing-box which contains suitable packing 3 to prevent leakage.

At the top end of the valve-stem u there is a curved arm 4, arranged to be acted upon by a f rictionroller 5, journaled in a swinging frame 6, mounted on a pin 7 in a bifurcated or i double operating-arm 8, which extends l from a plate N, and which plate is secured to the-under side of the lid E. At the outer end of this operating-arm and extending across the same there is a bridge 9, which serves to strengthen the arm and also forms a stopto limit the upward movement of the frame 6,

and against which stop the said frame is held by a spring 10, coiled around the `pin 7 and having one of its ends passing through said pin and the other of its ends bearing against the under side of bridge 9, as more clearly shown in Fig. 7, the spring being so coiled and arranged as that its tendency to unwind itself will raise the frame 6 to the positions shown in Figs. l, 6, 7, and 8. The outer ends of the bifurcated or double arm S are enlarged to extend beyond the roller 5, and when the parts are assembled, as shown in Fig. 1, these enlarged portions extend down over the sides of the curved arm 4 of the valve-stem u and retain the latter in proper relation with the roller 5 while it travels backward and forward over the said curved arms. (See Fig. 2.)

The operation of the above-described mechanism is as follows: When the lid Eis down, as shown in Fig. 1, the roller 5 is at rest and the valve is closed and so held by the spring and as the lid is raised the roller willtravel over the curved arm, the curvature of which is such as to cause the roller to depress the valve-stems and open the valve, which allows water to enter the chamber n, as indicated by Vthe arrows 2 in Fig. 4, and iiow through the inlet e into the iiushing-chamber c `and thence through the perforations d into and over the inner surface of the bowl ct of the hopper A, thereby flushing the closet. radius in which the roller 5 travels isgoverned by the pintles of the hinges by which the lid is hinged to the shelf F, and the valve mechanism is so arranged that when the lid` begins to swing upward the downward movement of the operating-arm 8 will cause the roller 5 to act upon the curved arm 4, thereby depressing the valve-stems and opening the valve, as hereinbefore recited, and this operation will continue until the lid reaches a position which frees theV curved arm from the roller, as shown by dotted lines in Fig. 2, when the pressure of the spring will close thevalve and shut off the water from the closet. Then as the lid is closed the frame 6 being free to swing on the pin 7 in an` opposite direction and against the pressure of the spring l0, (the latter being of lessresistance than the spring 413,) the "alve will be held closed during the downward movement of the lid and until the latter is raised again, when the roller 5 will be in position to rengagethe curved arm 4 and open the valve upon the next raising of the lid.

It is obvious that by locating the stop or bridge 9 on the under side of the operating arm 8 and reversing the spring 10 the valve will open on the downward movement ofthe lid instead of its upward movement, as above described; also, that by dispensing with the frame 6 and mounting the roller 5 directly in the operating-arm, lengthened accordingly, the `valve may be arranged to open on both the upward and downward movements of the `The IOO

lid, and that with slight mechanical changes the valve-operating arm may be applied to the seat and the lid dispensed with.

Various other modifications in structural details may be made without departing from the spirit of my invention. Therefore I do not limit my invention to the exact construction shown and described.
