Quick set and release clamping device
First Claim
1. A quick set and release clamping device comprising:
- a frame having a first workpiece engaging member and a transverse bore therethrough and further having an inner leg and an outer leg, said inner leg further having an inner side and an outer side, said transverse bore extending through an end portion of said inner leg and further having a tapered end in said inner side of said inner leg, said tapered end defining a seat portion in said transverse bore;
a threaded rod having a handle and capable of being freely moved back and forth through said transverse bore and further having a second work piece enraging member which in cooperation with said first work piece engaging member, is for clamping a work piece therebetween; and
a means to threadingly engage and disengage said threaded rod and to effect clamping of said work piece with said threaded rod and further comprising a pair of mirrored half bodies movably and biasedly disposed in said seat portion;
a retaining cover for housing said half bodies and for limiting movement of said half bodies; and
a detent movably mounted to said inner leg and engagingly biased to said retaining cover to releaseably urge said half bodies into engagement with said threaded rod extending through said transverse bore;
each of said half bodies having a front end and a back end and further having at least three sides, a first of which has a threaded groove extending from said front end to said back end and is facing said first side of said other half body, a second of which is opposed to said first side and is tapered from said front end to said back end so that said half bodies are fittingly received and seated in said seat portion, and a third of which has a slot therein and is disposed generally in a plane with said third side of said other half body.

Abstract
A quick set and release clamping device comprising a frame having an inner leg and an outer leg fixedly spaced from each other, a threaded rod freely movable through a transverse bore in the end portion of the inner leg, a first work piece engaging member fixedly attached to the end of the outer leg, a second work piece engaging member swivelly connected to the threaded rod, a pair of rod engageable half bodies slidable in a tapered end of the transverse bore for engaging the threaded rod, a retaining cover to house and restrict movement of the rod engageable half bodies, a detent to urge the half bodies into the seat portion of the transverse bore and to engage the threaded rod, a spring to urge the rod engageable half bodies slightly out of the tapered end of the transverse bore, a biased element for urging separation of the rod engageable half bodies, and a spring member to urge the detent against the cover. The rod engageable half bodies provide threaded surfaces to urge and grip the threaded rod into a clamping position in cooperation with the first work piece engaging member.
