Patented Sept. 2, 1952 VALVE RESEATING TOOL Arthur B. Utley, Springfield, Mo., assignor of onehalf to Bowman & Drussa Plumbing and Heating 00., Springfield, Mo.

Application August 9, 1949, Serial No. 109,257

1 Claim. 1

This invention relates to a tool designed primarily for use by plumbers in reseating flush valves of flush tanks used in connection with closet bowls.

An important object of the invention is to provide a grinding tool which may be effectively operated below the valve guide of the flush tank, eliminating the necessity of removing the valve guide or other fixtures of the fiush tank in order to reseat the valve.

Another important object of the invention is to provide a tool of this character which is so shaped that it will exactly fit the seat of the flush tank valve to the end that by applying slight pressure and rotating the tool, the valve seat may be reconditioned, eliminating the necessity of replacing the valve seat.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawing:

Figure 1 is an elevational view of a valve seat grinding tool, constructed in accordance with the invention.

Fig. 2 is a plan view thereof.

Fig. 3 is a vertical sectional view through the tool. Referring to the drawing in detail, the tool comprises a grinding stone 5 which has its lower surface curved as at 6 so that it will fit into the valve seat of the flush valve of a flush tank. As shown by Fig. 2 of the drawing the grinding stone is circular in formation.

The reference character I indicates the handle of the tool, which is constructed preferably of wood and is provided with an irregular outer surface 8 so that the handle may be gripped to rotate the grinding stone on a valve seat.

The stone 5 and handle I are provided with aligning openings through which the bolt 9 is extended, the bolt 9 being provided with a threaded end on which the nut I0 is mounted to draw the stone and handle securely together.

In the use of the tool, the usual flush valve is elevated and the tool positioned with the grind ing stone 5 resting in the valve seat. The tool is now rotated on its seat with the result that the valve seat will be reconditioned for proper seating of the flush valve, the reseating operation being carried out without the necessity of removing any of the valve mechanism within the flush tank.

It might be further stated that preferably the stone 5 embodies such abrasive material that will effectively recondition valve seats, either brass or porcelain.

Having thus described the invention, what is claimed is:

A valve seat reconditioningtool comprising a relatively thick solid disk shaped body of abrasive material havin an axial bore extending therethrough and parallelfaces on opposite sides thereof, the peripheries of said faces lying in concentric spaced relation to the bore, a relatively short handle abutting one face of the body, means extending through the bore and through the handle to secure the body to the handle, a convex toric surface on the body extending from the periphery of the body to the periphery of the face thereof remote from the handle, and said body diminishing in cross section as it approaches the face thereof remote from the handle.
