| Victor J. Evans - patent attorney
This invention relates to a wrench of the quick-adjusting type, and more particularly to a wrench having a shank provided with serrations with which a cam-actuated clamping block is adapted to engage for holding the movable jaw in set position. The invention has for one of its objects to improve and simplify the construction and operation of devices of this character so as to be comparatively easy and inexpensive to manufacture, of durable and substantial design, and composed of few parts. Another object of the invention is the provision of a wrench having a serrated shank with which a serrated clamping block mounted on the movable jaw is adapted to engage for holding such jaw in fixed position, the block being operated by a pivoted cam that is held in locking position by a spring and is adapted to be retracted by a lever connected therewith when it is desired to adjust the movable jaw. |
