ABSTRACT:
A motor driven picture framing vise mounts a pair of finger tip control buttons on the vise table convenient to the operator for locking and releasing the vise. A post and support arrangement provides adjustable vertical positioning of the vise table and swinging of the table around horizontal and vertical axes suited to particular picture framing operations. Interchangeable wedges allow various frame angles, e.g., rectangular, hexagonal and octagonal, to be joined and railing adjustments enable a wide latitude in thickness of the framing being joined.
