    摘要： A device for gripping a wire rope or the like wherein a pair of opposed jaws are urged longitudinally of the rope and camming means is provided for urging the jaws toward each other into gripping relation with the rope in response to such longitudinal movement. The particular combination of gripping jaws and camming surfaces achieves an optimum gripping effect. In the illustrative form of the invention the device on which the gripping means is used moves along the length of a fixed rope. Means is provided for actuating the gripping jaws when the relative speed between rope and device exceeds a predetermined amount regardless of whether the rope or the device is stationary.

    摘要： A brake for use with a shaft rotatably driven for raising a load and for automatically braking rotation of the shaft when the driving means is stopped or fails. Relatively shiftable camming members are employed to apply a frictional braking force against yieldable resistance and means is provided for creating a braking force that is not directly proportional to the amount of the load involved. In one form of the invention, a plurality of pairs of camming surfaces are provided; one pair cooperating to apply the braking force when the load is relatively light and an additional pair or pairs of camming surfaces are provided to resist heavier loads. By this structure, light loads are adequately held by a brake that is, of necessity, designed for relatively heavy loads. In addition, the instant load brake permits the brake to be easily released when the load is lowered without requiring excessive torque to effect such release thereby eliminating brake chatter and reducing wear and heat. The brake shoes of the load brake are urged against the opposite outwardly facing surfaces of a pair of brake plates which in turn are yieldably urged outwardly toward the brake shoes. In the preferred form of the invention, a cam follower is provided which cooperates with a camming surface which is formed to a progressively increasing slope as the angular displacement between the camming members increases, thus insuring easy release of the brake as well as adequate braking of the load regardless of the magnitude of the latter. An automatic adjustment device is also provided which insures that wear within the brake will be compensated for without affecting the behavior of the brake.

    摘要： A hoisting device of the type in which a rope is wound around a drum to provide a plurality of windings in side by side substantially parallel relationship. The shunting of the rope from one winding to the adjacent winding and the tensioning of the rope is accomplished by rollers so as to provide automatic self-reeving action and to reduce power loss due to friction as well as minimizing rope wear and enhancing reliability of the hoisting apparatus.
