Abstract
Abstract A flow-control valve having a valve member operated by a rotatable handle, the handle being selectively lockable to an extending portion of the valve casing at either the open or closed position of the valve member, and being selectively removable from the valve casing. The extending portion of the valve casing is a U-shaped locking post having extending legs with aligned openings therein, and the valve handle includes a locking plate portion having two locking projections each formed with an opening therein and an intermediate removal recess, the valve handle being rotatable between a first valve open position at which one of the locking projections is within the U-shaped locking post legs with the opening therein aligned with the locking post leg openings, a valve closed position at which the other locking projection is within the locking post legs with similarly aligned openings, and an intermediate removal position at which the locking plate portion is clear of the locking post to permit removal of the locking handle. Preferably, the locking plate portion of the valve handle also includes a stop disposed adjacent each locking projection for abutting the locking post at the valve open and valve closed positions of the valve handle, respectively, for accurately positioning the valve handle with respect to the locking post.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
256 words
A flow-control valve including a valve casing having a Ushaped locking post extending therefrom to present spaced leg portions having aligned openings formed therein, a valve member movable within said valve casing between selected first and second dispositions thereof, and a valve handle associated with said valve member for moving said valve member between said selected dispositions thereof, said valve handle including a locking plate portion formed with first and second locking projections each having an opening therein and a removal recess extending between said first and second projections, and said valve handle being mounted for selective shifting between a first position at which said valve member is at said first disposition thereof and one of said locking projections is disposed between said leg portions of said locking post with the opening in said one locking projection being aligned with said aligned openings in said locking post leg portions, a second position at which said valve member is at said second disposition thereof and the other of said locking projections is disposed between said leg portions of said locking post with the opening in said other locking projection being aligned with said aligned openings in said locking post leg portions, and a removal position, intermediate said first and second positions, at which said removal recess of said locking plate portion is disposed adjacent said locking post and beyond the extent of one of said leg portions thereof whereby said locking plate portion is clear of said U-shaped locking post to permit removal of said valve handle.
Claim 2
Dependent Claim
256 words
A flow-control valve including a valve casing having a Ushaped locking post extending therefrom to present spaced leg portions having aligned openings formed therein, a valve member movable within said valve casing between selected first and second dispositions thereof, and a valve handle associated with said valve member for moving said valve member between said selected dispositions thereof, said valve handle including a locking plate portion formed with first and second locking projections each having an opening therein and a removal recess extending between said first and second projections, and said valve handle being mounted for selective shifting between a first position at which said valve member is at said first disposition thereof and one of said locking projections is disposed between said leg portions of said locking post with the opening in said one locking projection being aligned with said aligned openings in said locking post leg portions, a second position at which said valve member is at said second disposition thereof and the other of said locking projections is disposed between said leg portions of said locking post with the opening in said other locking projection being aligned with said aligned openings in said locking post leg portions, and a removal position, intermediate said first and second positions, at which said removal recess of said locking plate portion is disposed adjacent said locking post and beyond the extent of one of said leg portions thereof whereby said locking plate portion is clear of said U-shaped locking post to permit removal of said valve handle.
Claim 3
Dependent Claim
118 words
A flow-control valve as defined in claim 1 and further characterized in that said valve handle locking plate portion is formed with a first extending stop portion located adjacent one of said locking projections on the opposite side thereof with respect to said removal recess in said locking plate portion, said first stop portion being arranged to abut said locking post at said first position of said valve handle, and a second extending stop portion located adjacent the other of said locking projections on the opposite side thereof with respect to said removal recess in said locking plate portion, said second stop portion being arranged to abut said locking post at said second position of said valve handle.
Claim 4
Dependent Claim
109 words
A flow-control valve as defined in claim 1 and further characterized in that said valve member is rotatable in said valve casing and includes an operating shaft extending outwardly from said valve casing for rotating said valve member, in that said valve handle is mounted on said operating shaft for rotating the same, in that said locking plate portion of said valve handle is disposed in a plane lying in perpendicular relation to said operating shaft, and in that the leg portions of said U-shaped locking post extend toward said operating shaft in parallel relation to the plane of said locking plate portion and on each side thereof, respectively.
