CANADIAN PATENT APPLICATION OF ROLF CARLMARK FOR WRENCH Abstract of the Disclosure: A wrench comprises a handle and a gripping mouth which is defined by two jaws, one of which is fixed and the other movable. The movable jaw is associated with a rack engaging a gear which is rotatably mounted relative to the handle and actuated by at least one spring constantly striving to rotate the gear in a direction such that the jaws are moved towards one another, said gear cooperating with a locking device which can be set in two different positions, a first position in which the gear is freely rotatable, and a second position in which the gear is non-rotatable and in which the gear, in turn, renders displacement of the movable jaw relative to the fixed jaw impossible.
