Abstract
A jaw adapter for use with exceptionally thick stock is provided for a clamp in which two jaws are moved along rails relative to each other to clamp boards between them. Such jaw adapter includes a pair of parallel plates with face plate supporting arms to abut and extend above a jaw of the clamp, and includes rollers rotatably mounted in the plates to extend transversely of the rails and support the jaw adapter thereon.
Claims12
A jaw adapter to mount upon the frame of a clamp having relatively movable jaws and increase the effective height of one of the jaws during the clamping of stock between them, the jaw adapter having a front side engageable above the jaws with clamped stock and having a rear side engageable with the face of said one jaw, the jaw adapter including means to contact the frame and facilitate longitudinal movement of the jaw adapter thereon, said means including a member disposed to resist by transversely engaging the frame any tendency of the upper part of the jaw adapter to tilt against said one jaw and concentrate force at the upper portion of said one jaw during the clamping of stock.
In a clamp, the combination of a frame including rigidly connected spaced rails, a fixed jaw and a movable jaw on the rails to receive stock between the jaws, means for moving said movable jaw toward and away from said fixed jaw to clamp and release said stock respectively, a jaw adapter for each jaw mounted on said rails and including a rockable plate on its front side, engageable above the jaw with the stock to increase the effective height of the jaw during the clamping of stock, such jaw adapter being engageable on the rear side with the front of the jaw, each of the jaw adapters including means extending transversely of and in contact with the rails to facilitate longitudinal movement of the jaw adapters thereon, said means on each jaw adapter including a rotable member disposed therein to resist by engagement with the rails, when stock is clamped, any tendency of the upper part of the jaw adapter to (pivot on the rails in a direction tending to cause the jaw adapter to apply force primarily to) tilt against the jaw and concentrate force at the upper portion (of the contacted jaw) thereof.
