My invention relates to such a construction oi' a bench-vise that thereby I am enabled to secure a perpendicular movement ofthevise, which is so made that, by an arrangement of tongues and grooves, itlwill slide up and down between two standards or sideways, it being raised and secured by means of a lover and pin, or by a set-s crewfplaced under its lower end, and operating upward against it 5V and' j", in the side oi' the standard rf as a i'ulcrum, l and w-orks against another pin or nojection,

g, on the back oi' the sliding inner jaw, b, so that when the long arm ol' the lever pressed down it raises the sliding jaw o by the short I arm pressing up against the pin ff, the onteijaw being raised along with it. The pin l1, which passes through the two uprigliis ofthe Standard, Fig. a, is for supporting the jaw I after it has been raised bv the leverj. The

By these arrangements I am enabled to raise or lower my vise quickly I ndeas1ly,and also to use many of my ioolswith greater advantage than heretofore-as, for instance, the
