Abstract
334,157. Dohnal, J. Jan. 23, 1930. Vices.-A screw clamp has a metal strap b slidable on a guide bar a and clamped to the bar by a lever c carrying the screw. The lever is divided longitudinally so that when the work is clamped the ends are sprung apart and pressed against the rounded edges of the guide bar, thus preventing the strap and lever from moving.
