Abstract
Abstract The fastener includes a head carrying a clamping jaw and an opening in which a rod is slidably received. Registering slots on the head and rod receive one end of a locking lever which is pivotally connected to the head. The opposite end of the lever carries a clamping jaw. A pin is carried by the rod and engages in a slot on the one lever end whereby reciprocating movement of the rod moves the jaw carried by the lever toward and away from the fixed clamping jaw. To retain the fastener clamped about a support, a locking sleeve is threaded on the rod. By threading the sleeve into butting engagement against the head the jaw carried by the lever is maintained in engagement against the support. The opposite end of the rod pivotally mounts a lighting fixture or the like.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
154 words
Apparatus for releasably coupling a fixture to a support comprising: a head including a body carrying a clamping jaw and having an opening, a rod having an end portion slidably received in said opening, a lever pivotally carried by said head and carrying a clamping jaw at one end thereof in opposition to said first mentioned jaw, means for pivotally connecting said lever and said rod end portion on the side of the pivotal axis of said lever opposite its jaw whereby movement of said rod away from said head pivots the jaw carried by said lever toward said first mentioned jaw for clamping the support between said jaws, means cooperable between said rod and said head for locking the jaw carried by said lever against pivotal movement in a direction away from said first mentioned jaw, and means carried by one of said rod and said locking means for securing a fixture thereto.
Claim 2
Dependent Claim
154 words
