FLUSI'IING-VALVE GUIDE g No. 889,609.

To all whom it may concern:

Be it known that I, CHARLES L. HOLDEN, a citizen of theUnited States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented new and useful Improvements in Flushing-Valve Guides; and I do declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to flushing valves of tanks that are used with water-closets, and has reference particularly to the guides for the valves and to the supports of the guides.

Objects of the invention are to provide a stable and reliable su port for the valve guide that is required or guiding the flush in valves that are each provided with a va ve stem; to provide a removable guide which may be easily detached from its support in order to substitute a new valve for an old one; to provide a self-adjusting guide and support therefor that will enable the repairer to quickly replace the guide on its support with accuracy, so that the new valve may fit its seat exactly as it should do and, further, to provide a guide construction which will insure the replacement-of the guide in the same position as that in which it had previously been used, without requiring measurements or time-occupying expedients.

The above-mentioned and minor objects are attained in the present invention, which consists in a flushing valve having a rigid valve-guide support cast integrally with the valve-seat body member so that the support may be fitted accurately with respect to the valve-seat, the su ort having a guide-bar thereon, and a gui e having a self-adjusting collar fitting the support and having a guidegroove to receive the guide-bar, with a setscrew opposite to the guide-groove for securing the collar to the su port; and, the invention consists further in the parts and the combinations and arrangements of arts, as hereinafter particularly describe and claimed.

Referring to the drawings, Figure 1 is a vertical longitudinal sectional view of a flushing tank with which the improved valve guide and support, as preferably constructed, is connected and shown, the float lever being Specification of Letters Patent.

tive view of the guide and its appurtenances;

and, Fig. 5, a horizontal sectional view approximatelycorresponding to the plane of the line AA in Fig. 2.

Similar reference characters in the several figures of the drawings designate corresponding elements or features.

In a practical embodiment of the invention, the improvement is used in connection with a flushing-tank at having an inlet-valve b operated by means of a float c. A valveseat body 61 has a valve-seat e on which a valve f o erates in a well-known manner to control t 1e flushing operations, the valve having a stem g, and a lever h is pivoted to the tank and is connected by a link i with the valve-s.tem. The body (1 being secured rigidly to the bottom of the tank, the flushingpipe as usual is to be attached to the body beneath the tank. The body (1 is formed as a casting as usual, and the guide support B has a base 1', all cast integral with\the body d, there being a'duct j in the support and its base communicating with the interior of the body at below the seat a, so that the support may be used as an overflow duct, as a matter of economy, although a separate overflow pipe may be rovided, if desired, in which case the top of the support B may be closed. The support B is upright and at the upper end thereof it has an annular external seat k which is formed accurately and is preferably tapering, and at one side thereof the seat has an integral vertical guide-bar Z that preferabl is wed e-sha e bein narrower at its b i O seat 7c, the finishing of both being done exactly by means of jigs and gages with respect to the seat e, so that any collar C may be used on any seat 7c with precision. In one side of the collar 0 a groove 9 is formed which corresponds to the sha e of the guide-.

bar Z, and a set-screw r is fitte into the o posite side of the collar so that the end 0 the set-screw may be forced against the seat 7c for securing. the collar thereto. The oppo-. site end of the arm 0 has a bore 8 therein that is true with the axis thereof in alinement with theaxis of the bore of the seat e, and the stem g is guided in the bore. By the use of proper tools the bore maybe made accurately in any number of guides, so that they may be interchangeable with the supports B, thus lessening the cost of manufacture below that required in fitting each guide separately to a crooked or inaccurate overflow pipe in the old way.

It is well known that the valves f deteriorate, being com osed of rubber composition, and must be replaced by new valves. With the improved construction above-described, the set-screw may be loosened and the collar C easily removed from its seat is after having disconnected the link i; then the stem 9 may be unscrewed from the valve. A new valve may then be applied to the stem, or a new stem may be supplied if required, and the collar may be replaced on its seat and secured by the set-screw, with the valve fairly in proper position on its seat. In replacing the co lar, the guide-bar Z will readily be received into the groove q so as to guide the arm C to the proper position, the guide-bar serving as a look when the collar is seated to prevent displacement of the arm and the guide bore 8. In practical use the operations and results thereof are so well understood as to require no further descri tion.

Having thus describe( the invention, what is claimed as new is 1. In a flushing valve, the combination of a valve body member with a valve-seat therein, the body member having a valve guide support formed integral therewith, the support eing hollow with the interior thereof in communication with the interior of the body member below said valve seat, a portion of said support being tapered externally and having a guide-bar formed integrally on said tapered portion, and an annular collar seated removably on said tapered portion and having a groove receivin said guide-bar, with an arm rigid on said collar, and a valve on said seat with a stem guided by said arm.

2. In a flushing valve, the combination of a valve body member with a valve seat therein, the body member having a valve guide support formed integral therewith, the su port being hollow with the interior thereof 1n communication with the interior of the body member below said valve-seat, a portion of said support being tapered externally and having a guide-bar formed integrally on said tapered portion, an overflow pipe attached removab y to the top of said support, an annular collar seated removably on said tapered portion and having a groove receiving said guide-bar, and a set-screw in said collar engaging said tapered portion, with an arm rigid on said collar and a valve on said seat with a stem guided by said. arm.

3. In a flushing valve, the combination of a valve body member with a valve-seat,

therein, the body member having a valve guide support formed integral therewith, the support being hollow with the interior thereof in communication with the interior of the body member below said valve-seat, a portion of said support being tapered externally and having a guide-bar formed integrally on said tapered portion, the interior of said tapered portion having screw threads, an overflow pipe having screw threads connected to the threads of the support, an annular collar seated removably on the ta ered portion and having a groove receiving t e guide-bar, and a set-screw in said collar engaging the tapered portionof the support, with an arm rigid on said collar, and a valve on said seat With a stem guided by said arm.

In testimony whereof, I affix my signature in presence of two witnesses.
