Abstract
Abstract A water valve adjustable stem assembly includes a valve housing with an inlet and outlet therein and a valve positioned within the housing. The valve has an inlet and outlet communicating with the housing inlet and outlet and there is a movable valve member to open and close the valve. A valve housing extension is adjustably connected to the valve housing and connects to an escutcheon. A stem extension is attached to the movable valve member and extends within the housing and housing extension and adjustably supports a stem connected thereto. An operating handle is connected to the stem and spaced closely adjacent to the escutcheon. The valve housing is mounted to an underlying support and the adjustment between the valve housing extension and valve housing and the adjustment between the stem extension and stem provides for variably positioning the handle and escutcheon relative to the valve housing mounting.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
223 words
A water valve adjustable stem assembly including a valve housing having inlet and outlet means therein, a valve positioned within said housing and having a rotable operating member and inlet and outlet means in communication with said housing inlet and outlet means, an escutcheon, a valve housing extension attached to said escutcheon and adjustably connected to said valve housing, a stem extension attached to said operating member and extending within said housing and said housing extension, a stem adjustably connected to said stem extension and a handle connected to said stem, said stem being slidably positioned within said stem extension, and means for fixing the relative position of said stem and stem extension including a plurality of spaced, generally circumferentially extending grooves on the exterior of an upper portion of said stem, a ring positioned to fit within a groove, and a nut threadably attached to the exterior of the stem extension and positioned to overlie the end of said stem extension and position said ring within a stem groove to thereby fix the position of the stem relative to the stem extension, means for mounting said valve housing, the adjustment between said valve housing extension and valve housing and the adjustment between stem extension and said stem providing for variably positioning said handle and escutcheon relative to said valve housing mounting means.
Claim 2
Dependent Claim
223 words
A water valve adjustable stem assembly including a valve housing having inlet and outlet means therein, a valve positioned within said housing and having a rotable operating member and inlet and outlet means in communication with said housing inlet and outlet means, an escutcheon, a valve housing extension attached to said escutcheon and adjustably connected to said valve housing, a stem extension attached to said operating member and extending within said housing and said housing extension, a stem adjustably connected to said stem extension and a handle connected to said stem, said stem being slidably positioned within said stem extension, and means for fixing the relative position of said stem and stem extension including a plurality of spaced, generally circumferentially extending grooves on the exterior of an upper portion of said stem, a ring positioned to fit within a groove, and a nut threadably attached to the exterior of the stem extension and positioned to overlie the end of said stem extension and position said ring within a stem groove to thereby fix the position of the stem relative to the stem extension, means for mounting said valve housing, the adjustment between said valve housing extension and valve housing and the adjustment between stem extension and said stem providing for variably positioning said handle and escutcheon relative to said valve housing mounting means.
