摘要： A plurality of uniform pieces are gripped between the jaws of a vise by the exposed sides of individual turns of a coil spring disposed between the vise jaws. Preferably, several springs are housed in bores in a block with the turns of the spring extending from the face of the block for gripping pieces. The block is supported on a vise jaw and includes a plate compressing the springs within the bores so that their turns are contiguous.

摘要： A workpiece measuring device is arranged to interrupt an automatic metal working machine if workpieces are short. The device includes a feeler movably mounted to extend into the path of relative motion of the machine''s index mechanism for indexing tools or workpieces. An electric switch is operated by the feeler when workpieces of adequate length engage the feeler and move it during indexing. The switch is arranged in an RC circuit that interrupts the machine after lapse of an interval slightly exceeding the time for one cycle of the indexing mechanism, and actuation of the switch for each workpiece of adequate length disables the interruption to allow the machine to continue operation so long as no short or missing workpieces are encountered by the feeler.

摘要： A control for a strip heater supported on a frame uses a lever pivoted on the frame to have a short lever arm engaged by a carriage carrying the movable end of the strip and a long lever arm coupled to an adjustable element in an electric circuit having a variable power output for energizing the strip.

摘要： A gripper with fixed and movable flanges squeezed together axially as a function of applied force to move an elastomeric ring radially for gripping uses an elastomeric ring that has a crowned gripping surface that is generally convex in axial cross section when the ring is unstressed. The opposite surface of the ring is generally concave in axial cross section, and the ring is supported on a cylindrical surface so that the axially central region of the ring is free to move radially toward the support surface. Such a ring can grip the outside of the shaft or the inside of a core for turning or lifting. Also, several improved actuators drive the movable flange as a function of the applied force.
