Abstract
Abstract A valve having body and bonnet and including a stem shiftable longitudinally in the bonnet. A valve member is mounted to the inner end of the stem and cooperates with a valve seat in the valve body to control the flow rate through the valve. A hand grip is mounted on the outer end of the stem. A stop member is attached to the stem between the hand grip and bonnet and includes a part which is adjustable relative to and shiftable with the stem and a part which is engageable with a stationary projection carried by the valve to limit valve opening movement of the stem.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
171 words
In a fluid valve comprising a housing having an inlet, an outlet and a valve seat, a stem shiftably carried by said housing and including an inner part which projects into said body housing and which mounts a valve member and an axially shiftable outer projecting part which mounts a grip, said valve member cooperating with said valve seat to regulate fluid flow through said valve outlet as said outer stem part is axially shifted, the improvement comprising stop means attached to said outer stem part between said grip and said housing and including an abutment shiftable with said outer stem part, and a stationary stop carried by the housing and positioned between said grip and said abutment and projecting into the path of movement of said abutment to limit the extent to which said valve may be opened, said abutment being movable relative to said outer stem part and said stationary stop to vary the spacing between said stationary stop and abutment along the path of movement of said abutment.
Claim 2
Dependent Claim
171 words
In a fluid valve comprising a housing having an inlet, an outlet and a valve seat, a stem shiftably carried by said housing and including an inner part which projects into said body housing and which mounts a valve member and an axially shiftable outer projecting part which mounts a grip, said valve member cooperating with said valve seat to regulate fluid flow through said valve outlet as said outer stem part is axially shifted, the improvement comprising stop means attached to said outer stem part between said grip and said housing and including an abutment shiftable with said outer stem part, and a stationary stop carried by the housing and positioned between said grip and said abutment and projecting into the path of movement of said abutment to limit the extent to which said valve may be opened, said abutment being movable relative to said outer stem part and said stationary stop to vary the spacing between said stationary stop and abutment along the path of movement of said abutment.
Claim 3
Dependent Claim
18 words
The valve of claim 1 wherein said stop means includes a reduced cross-sectional frangible part adjacent said abutment.
Claim 4
Dependent Claim
24 words
The valve of claim 1 wherein said housing includes a packing nut encircling said stem, said stop forming a part of said packing nut.
Claim 5
Independent Claim
172 words
A device for limiting the Opening of a fluid valve including a housing having a valve seat therein, a stem threaded in said housing and axially shiftable upon rotation, grip means mounted on the outer end of said stem and a valve member mounted on the inner end of said stem and cooperable with said valve seat to regulate fluid flow through said valve comprising stop means attachable to said stem in selected position between said grip means and said housing and including a part positionable in an offset lateral relationship from said stem and carrying an abutment shiftable with said stem, a stationary stop adapted to be carried by the housing and positionable so as to project into the path of movement of said abutment and be contacted thereby when said stem is rotated to open said valve to a selected extent, said abutment being movable relative to said stem and stationary stop to vary the spacing between said abutment and stationary stop along the path of movement of said abutment.
Claim 6
Independent Claim
172 words
A device for limiting the Opening of a fluid valve including a housing having a valve seat therein, a stem threaded in said housing and axially shiftable upon rotation, grip means mounted on the outer end of said stem and a valve member mounted on the inner end of said stem and cooperable with said valve seat to regulate fluid flow through said valve comprising stop means attachable to said stem in selected position between said grip means and said housing and including a part positionable in an offset lateral relationship from said stem and carrying an abutment shiftable with said stem, a stationary stop adapted to be carried by the housing and positionable so as to project into the path of movement of said abutment and be contacted thereby when said stem is rotated to open said valve to a selected extent, said abutment being movable relative to said stem and stationary stop to vary the spacing between said abutment and stationary stop along the path of movement of said abutment.
Claim 7
Dependent Claim
31 words
The device of claim 4, and including a packing nut adapted to encircle said stem and threadably engaged said housing, said packing nut constituting the stationary stop engageable by said abutment.
Claim 8
Dependent Claim
68 words
The device of claim 4 wherein said stop means includes a support part adapted for attachment to said stem between said grip means and said housing and having a releasable clamp means spaced from said stem, said first mentioned part including a stud adjustably anchored by said clamp means said abutment including a flange member mounted adjacent one end of said stud and engageable with said stationary stop.
Claim 9
Dependent Claim
