BY -mg FLUSH VALVE George Myers, Jefferson County, Tex. Application May 22, 1953, Serial No. 356,627 2 Claims. (Cl. 4-57) This invention relates to water discharge flush valves as are employed in conventional flush tanks or toilets and more particularly to an improved ball valve guide means.

It is the primary object of this invention to provide guide means for the ball valves of flush tanks that is extremely easy to install and which is vertically and horizontaily adjustable to insure that the ball valve will be accurately guided to its seat.

A further object of the invention resides in the provision of means for frictionally adjustably securing a tubular guide within a water discharge flush valve, the means frictionally engaging the interior walls of the discharge conduit at any selected position.

Still further objects of the invention reside in the provision of a flush valve construction that is strong and durable, simple in construction and operation, capable of being substituted for conventional flush valves, and which is relatively inexpensive to produce.

These, together with the various ancillary objects and features of the invention which will become apparent as the following description proceeds, are attained by this fiush valve, a preferred embodiment of which has been illustrated in the accompanying drawings, by way of eX- ample only, wherein:

Figure 1 is a perspective view of the flush valve comprising the present invention with parts thereof being broken away to show the tubular guide and the means for frictionally adjustably securing the guide within the dis charge conduit in greatest detail;

Figure 2 is a top plan view of the flush valve;

Figure 3 is a vertical sectional view of the flush valve illustrating the construction of the means for accurately guiding the ball valve to its seat;

Figure 4 is a horizontal sectional view as taken along the plane of line 4-4 in Figure 3; and,

Figure 5 is a sectional detail view illustrating a modified form of means for guiding the ball valve to its seat.

With continuing reference to the accompanying drawings wherein like reference numerals designate similar parts throughout the various views, reference numeral generally designates a guide bracket which is secured to an overflow pipe 12 and which is adapted to support an upper lift rod 14 threadedly engaged within the internally threaded centerpiece 16 of a ball valve 18 formed of rubber or other suitable resilient material which is adapted to seat on the valve seat 20 formed of the upper portions of a water discharge conduit 22. The discharge conduit 22 is externally threaded as at 24 permitting the discharge conduit to pass through the bottom of the flush tank 26 and to be secured in position.

Threadedly secured to the centerpiece 16 of the ball valve 18 is a pilot rod extension 28 which is adapted to extend through a tubular guide 30 mounted within the discharge conduit 22. The tubular guide 30 is externally threaded at its lower end 32 and is threadedly engaged within a guide block 34 having a pair of

divergent arms

36 and 38 extending outwardly therefrom. The

arms

36 and 38 are externally threaded at their free ends and have threadedly secured

thereto friction elements

40 and 42 atent provided with a knurled or otherwise roughened outer 7 surface.

2,735,112 Patented Feb. 21, 1956 As can be readily understood the tubular guide 30 can be adjusted vertically and horizontally by tightening or loosening

friction elements

40 and 42 thus permitting the tubular member 30 to be raised or lowered or to be offset horizontally depending upon the position of the

friction elements

40 and 42 relative to the arms 36 and 33, respectively. The

friction elements

40 and 42 will frictionally engage the inner surfaces of the conduit 22 and bite into the surfaces to hold the assembly in a selected adjusted position. Hence, when the upper lift rod 14 is raised the pilot rod extension 28 will be pulled up through the tube 30. When the pilot rod 14 is released the rod 23 will slide down through the tube 30 guiding the ball valve 18 to its seated position.

Referring now to the embodiment of the invention as is illustrated in Figure 5, it will be noted that herein the water discharge conduit 50 having a valve seat 52 has additionally the arms 54 integrally cast with the walls of the conduit and also has the guide block 56 integrally formed therewith. The guide block 56 is internally threaded for reception of the tubular guide 30 and this modified form of the invention functions in like manner as does the initially described device.

Since from the foregoing, the construction and advantages of this flush valve are readily apparent, further description is believed to be unnecessary.

However, since numerous modifications will readily occur to those skilled in the art after a consideration of the foregoing specification and accompanying drawings, it is not intended to limit the invention to the precise embodiment shown and described, but all suitable modifica tions and equivalents may be readily resorted to as desired.

What is claimed as new is as follows:

1. A flush valve comprising a discharge conduit having a valve seat at the upper portion thereof, a resilient ball valve adapted to be seated on said valve seat, a pilot rod depending from said ball valve, a tubular guide within said discharge conduit, said pilot rod extending into said tubular guide, and means secured to said tubular guide vertically and horizontally adjustably frictionally securing said tubular guide in said discharge conduit, the lower end of said tubular guide being threaded, said means including a guide block threadedly secured to said tubular guide, said guide block having a pair of divergent arms, and friction elements threadedly adjustably secured on said arms, the outer surfaces of said friction elements being roughened.

2. A flush valve comprising a discharge conduit having a valve seat at the upper portion thereof, a resilient ball valve adapted to be seated on said valve seat, a pilot rod depending from said ball valve, a tubular guide within said discharge conduit, said pilot rod extending into said tubular guide, and means secured to said tubular guide vertically and horizontally adjustably frictionally securing said tubular guide in said discharge conduit, the lower end of said tubular guide being threaded, said means including a guide block threadedly secured to said tubular guide, said guide block having a pair of divergent arms, said arms extending outwardly from said guide block and having outer ends, and friction elements adjustably secured on said outer ends of said arms.
