ABSTRACT:
An engineers' or carpenters' vise comprises a tubular outer member (12) having a plurality of apertures (13) aligned along one side of the member. A jaw is fixed to one end of the member. A second tubular inner member (18) is telescoped within the first member and has a plurality of apertures 19 which cooperate with the apertures (13) in the outer member. A movable vise jaw 20 is attached to the end of the inner member. A tapered lever 24 is provided for insertion into apertures which are not in line, so as to forcibly pry or move the inner member (18) in either one of two alternative directions. A tapered locking pin 22 is provided to securely lock the inner member (18) to the outer member (12), so as to prevent any return movement. The pin is inserted into apertures which are not in line. The inner member (18) can be removed from the outer member (12) and re-inserted into the opposite end of the outer member, so as to arrange the vise to have an even greater jaw opening.
