ABSTRACT:
A stop apparatus for use in attaching to a guide member of a piece of workship equipment includes a block, a clamp member, and a lever. The block has end and side surfaces and a cavity for receiving the clamp member and the lever. The clamp member has inner and outer portions with the inner portion being actuated by the lever and the outer portion being located exteriorly of the block end surface. A gap for receiving the guide member is formed between the end surface and the clamp member outer portion. The clamp member moves inwardly and outwardly to respectively clamp the apparatus to the guide member and release the apparatus. The lever is provided with an eccentric cam portion and a handle portion. As the lever is pivoted about a shaft by its handle portion, the eccentric cam actuates the clamp member to move inwardly or outwardly. An adjusting screw adjusts the position of the clamp member so that the apparatus can be clamped to fences of various widths. A groove is provided in the bottom surface of the block, for receiving a tape measure, wherein the block can be accurately positioned along the guide member.
