Abstract
Abstract A wall hydrant is described herein comprising a hollow tube having an inlet end and outlet end. The inlet end is adapted to be connected to a source of fluid under pressure and has a valve means adjacent its inlet end. The valve means comprises a cylindrical body portion having an inward end terminating in an arcuate nose portion. A plurality of spaced apart tab elements extend outwardly from the body portion and bear against the inward surface of the hollow tube. A valve seat portion is provided in the inlet end of the tube. A valve control rod is connected to the valve means and extends through the opposite end of the hollow tube to permit remote control of the valve means and to selectively permit the valve means to slide inwardly to a closed position on said tabs, and outwardly to an open position.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
228 words
A wall hydrant, comprising, a hollow cylindrical tube having an inlet end and an outlet end, a valve seat connector having an outwardly facing valve seat therein and opposite inner and outer ends, means for connecting said inner end of said valve seat connector to a source of fluid under pressure, means for connecting said outer end of said valve seat connector to the inlet end of said hollow tube, a valve means in said tube adjacent said inlet end, said valve means comprising a cylindrical body portion having inward and outward ends, with the inward end terminating in an arcuate nose portion, and a plurality of spaced apart integral tab elements extending outwardly from said body portion at the outward end thereof, said tab portions slidably engaging the interior surface of said hollow tube, said valve seat being complementary in shape to the arcuate nose portion of said valve means, and valve control means extending through said tube and being connected to said valve means to selectively longitudinally slide said valve means inwardly on said tabs to a closed position on said valve seat, and to selectively slide said valve means outwardly on said tabs to an open position whereby fluid may enter the inlet end of said tube and flow outwardly therethrough around said nose portion and said body portion and between said spaced apart tabs.
Claim 2
Dependent Claim
228 words
A wall hydrant, comprising, a hollow cylindrical tube having an inlet end and an outlet end, a valve seat connector having an outwardly facing valve seat therein and opposite inner and outer ends, means for connecting said inner end of said valve seat connector to a source of fluid under pressure, means for connecting said outer end of said valve seat connector to the inlet end of said hollow tube, a valve means in said tube adjacent said inlet end, said valve means comprising a cylindrical body portion having inward and outward ends, with the inward end terminating in an arcuate nose portion, and a plurality of spaced apart integral tab elements extending outwardly from said body portion at the outward end thereof, said tab portions slidably engaging the interior surface of said hollow tube, said valve seat being complementary in shape to the arcuate nose portion of said valve means, and valve control means extending through said tube and being connected to said valve means to selectively longitudinally slide said valve means inwardly on said tabs to a closed position on said valve seat, and to selectively slide said valve means outwardly on said tabs to an open position whereby fluid may enter the inlet end of said tube and flow outwardly therethrough around said nose portion and said body portion and between said spaced apart tabs.
Claim 3
Dependent Claim
14 words
The device of claim 1 wherein there are three tabs on said valve means.
Claim 4
Dependent Claim
42 words
The device of claim 1 wherein said hollow tube is comprised of metal material and said valve means including said tab portions are comprised of a rubber material to minimize the vibrational chatter of the valve with respect to the hollow tube.
Claim 5
Dependent Claim
42 words
The device of claim 2 wherein said hollow tube is comprised of metal material and said valve means including said tab portions are comprised of a rubber material to minimize the vibrational chatter of the valve with respect to the hollow tube.
