Hand tool for joining objects

摘要

A hand tool for assembling two or more articles along an extended plane. Arcuate motion of a movable handle is converted to axial movement of a presser plate to assemble the articles placed on an aligned platen. The movable handle controls a drive bar which is coupled to the tool frame by pivotally movable links which move the drive bar in two orthogonal directions and to the presser plate to move it in two orthogonal directions by means of pivotally movable links coupled to the drive bar. The movements along one orthogonal axis cancel one another and the movements along the other orthogonal axis are cumulative whereby the presser plate is moved only in the direction of the platen.
