VALVE ROD GUIDE FOR FLUSH TANKS Filed Aug. 11, 1936' INVENTOR Patented June 15, 1937 NITED STATES PATENT OFFICE VALVE ROD GUIDE FOR FLUSH TANKS Anthony Lancellotte, Pittsburgh, Pa. Application August 11, 1936, Serial No. 95,372

1 Claim. (01. 4-57) This invention relates to a valve rod guide The inner end of the support is provided with a for a flush tank, and important objects and adtransversely extending aperture I!) to allow the vantages thereof are to provide a durable and apertured ears I of the clamp band to be atefficient guide mechanism of the character detached against the respective sides of the supscribed, which will function to accurately seat port, by the screw 9, in the event that an over- 5 the ball valve of a flush tank on its associated size fiowpipe is used in conjunction with the valve seat and thus prevent the waste of water, improved guide. which embodies a novel bracing element, which is The support 5 is provided with a longitudinalsimple in its construction and arrangement, and 1y extending passage H open at both ends, for comparatively economical in its manufacture, the reception of a shank l2 carrying a pair of 10 use and maintenance.

The The lower end of the bracing frame I! is pro- 59 lug 8 is formed integral with the top of the vided with a pair of spaced, outwardly projectsupport and extends vertically upward at the ing feet 20, which partially surround and eninner end of the latter. The lug 8 is considergage the neck 2| of the valve seat I, and seat ably narrower than the width of the support, on the shoulder 22 of the latter, as clearly and is adapted for connecting the latter to an shown in Figure 1. overflow pipe of the conventional diameter. A rearwardly projecting yoke 23 is carried by the lower member 24 of the bracing frame H. The yoke 23 is spaced from the lower end of the bracing frame and engages and partially surrounds the overflow pipe 2.

The bracing frame I! is positioned so as not to interfere with the operation of the ball valve 3 in the valve seat I, and not only serves to brace the support 5 in its proper position, but also serves as a bracing structure for the overfiow pipe 2,

It will be obvious that in the use of my improved guide mechanism, the vertically aligned guide bearings l3 may be readily adjusted to any necessary position, by the adjustment of the shank l2 in the support passage II, in the manner stated, and by the adjustment of the clamping band 6 on the overflow pipe 2, to maintain the valve rod 4 in the proper vertical position to accurately seat the ball valve 3 on the valve seat I at all times, and thereby prevent water Waste from leakage due to an imperfectly seated valve.

What I claim is:

The combination with a flush tank valve mechanism including a valve seat, a valve rod and an overflow pipe, of a horizontally disposed support provided with a longitudinally extending passage, a clamping band surrounding the overflow pipe and connected with said support for attaching the latter to the overflow pipe, a shank mounted in said passage and longitudinally adjustable in the latter, means carried by said support and operable to engage said shank for securing the latter in the adjusted position, a pair of spaced vertically aligned guide bearings for the valve rod carried at the outer end of said shank, and a bracing element connected with said support resting on said valve seat and engaging the overflow pipe for bracing said sup- P rt.
