Abstract: A power-actuated vise apparatus includes a first jaw which is disposed on a base, and a second jaw which is supported by a carrier to be movable in a longitudinal direction by an angular force in an initial course. The carrier is further pressed by a linear force in a subsequent course to bring the second jaw into tightened engagement with a workpiece against the first jaw. A servo control mechanism is disposed to drive a torque transmitting member so as to transmit a torque force. A force coupler unit is configured to couple the torque transmitting member to the carrier and to take up the torque force from the torque transmitting member to result in generation of the angular force and the linear force.

Abstract: The present invention relates to a handling device for an anode connector provided with at least two side trunnions and a tightening screw. The connector is generally capable of cooperating with attachment hooks of an aluminum production cell used in fused bath electrolysis production operations so as to enable connection of anodes onto the cell. The handling device has a tightening device capable of tightening the connector screw and affecting the tightness of the connector. The present invention also has a locking system that can lock the connector in a desired position in the handling device, by loosening the connector using the tightening device. The handling device also has at least one mobile member which typically has a support to support the connector in a closed position. The support can also displace the mobile member from its closed position to an open position, and vice versa.

Abstract: A first clamping arm mounted to an arm rotary shaft is rotated by a driving mechanism formed of a worm wheel mounted to the arm rotary shaft, a worm supported on a junction frame, and a first driving source to clamp a workpiece between a second clamping arm and the first clamping arm. A rotating force in a direction opposite to a reaction force in clamping is applied by a clamping force applying mechanism to the junction frame which has been displaced through a certain angle by the reaction force to thereby generate a rotating force in a clamping direction in the arm rotary shaft through the worm and the worm wheel to thereby apply a clamping force to the first clamping arm.

Abstract: A clamp apparatus comprises a toggle link mechanism which converts rectilinear motion of a rod member into rotary motion, an arm which is rotatable by a predetermined angle in accordance with a driving action of a cylinder section, and a lock mechanism which holds an unclamping state of the arm even when transmission of driving force of the cylinder section to the arm is cut off.

Abstract: A rotary clamp having a linkage assembly that provides an over-center condition for providing high actuation and clamping forces without excessively wearing the components of the linkage assembly. The linkage assembly is connected to a linear actuator for converting linear actuator motion into rotary clamp motion between a clamped position and an unclamped position. The linkage assembly provides a first link having an aperture for receiving a pin and a roller wherein the roller is coaxially connected o the pin. The second link is pivotally connected to the first link, and the third link is pivotally connected to the second link. The roller of the first link rollably engages a surface on the third link when moving in and out of the clamped position. A beam-like structure connected to the housing provides a wear surface wherein the pin engages the wear surface in response to the roller engaging the third link to prohibit the first link from reaching an over-center position.

Abstract: A container holding apparatus is configured for use with an associated piece of testing equipment, such as a torque tester for applying torque to a closure on the container. The holding apparatus includes a pair of selectively positionable gripping members which are mounted on and extend between a pair of drive screws of the apparatus. One of the gripping members is operatively connected with a clamp mechanism, which in turn is mounted on the drive screws. By this arrangement, conjoint rotation of the drive screws moves the gripping members toward and away from each other, with the clamp mechanism facilitating convenient gripping and release of a container after the apparatus is adjusted, by rotation of the drive screws, for the particular size of container to be tested. In the preferred form, the apparatus includes a support plate upon which the container rests as it is releasably gripped and held by the gripping members.

Abstract: A twin screw vise utilizing two threaded vise screw rods that are journaled through flanged nuts fixed to a workbench top or to a rear, fixed bench jaw. The vise screws pass through a movable front jaw and into tee-castings and handles that may be turned to rotate the screws. Sprockets are located on each screw between the tee castings and the front jaw and are coupled by a chain. One of the sprockets is fixed in position on its screw during a calibration procedure. The other sprocket remains free to rotate on its screw, except when a spring loaded pin in the corresponding tee-casting engages a depression in the face of the sprocket, thereby coupling that sprocket to the tee casting and associated screw.

Abstract: A woodworking bench and related fixtures providing an integrated system of bench features, vises, dogs, panel clamps, hold-downs and fixtures that cooperate to provide a highly flexible workpiece holding and clamping apparatus able to accommodate a wide variety of shapes and sizes of workpieces and hold such workpieces in an enormous variety of positions during numerous different operations. Two substantial slabs provide the bench top surface and carry a rectilinear pattern (in rows and files) of round, vertical bench dog holes. The rectilinear pattern of round bench dog holes with specific, equal spacing between holes, and similar holes in the edge of the top, facilitate great flexibility in clamping using conventional round dogs in the bench top holes and corresponding dogs in bench edge-mounted, or end-mounted vises. Such holes also accommodate other clamping, fixing and hold-down fixtures that contribute to flexibility and utility.
