The drive pin can be moved within the body to engage a cam follower of the locking arm.

Abstract: A clamp having a pneumatic cylinder with an actuating rod connected to one end of a drive arm which has its other end attached to a crankshaft which in turn has crankpins eccentrically mounted thereon to drive inner and outer clamp arms between retracted and advanced positions corresponding to open and closed positions of the clamp. The length of the drive arm, the extent to which the crankpins are offset from the crankshaft, the specific portion of a quadrant through which the crankpins are rotated, and the distance between the application of the force to the clamp arms and the axes about which the clamp arms pivot all provide a significant mechanical advantage and an extremely large clamping force from relatively low pressure compressed air supplied to the pneumatic cylinder.

Abstract: A tool including two flat parallel flanges (2 and 3), defining between them a space (4) which corresponds to the thickness of a cutting blade (5) and including two symmetrical slots which have profiles that are roughly identical to that of a gutter (7) so as to constitute a guiding cradle for cutting the gutter by operation of the cutting blade (5) between flanges (2 and 3). The guiding cradle is defined by slots delimited in an upper zone by a convex contour (6b) of a fixed part of the flanges, and in a lower zone by the concave contour (6a) of a movable part, so that a movable part can be articulated at one of its ends around a fixed axis of rotation (8) like a jaw (9) in the open position (0), to allow free passage of the gutter (7) and in the closed position (F) constitutes a fixed support for cutting.

Abstract: A work fixture brake includes a first block and a second block and a brake disc. The first block has a first axis of rotation passing therethrough and a first friction pad fixed thereto. The second block is axially juxtaposed the first block and is pivotably connected thereto at a second axis of rotation offset from the first axis of rotation. A second friction pad is rotatively fixed to the second block. A brake disc has a first side facing the first friction pad and an oppositely disposed second side facing the second friction pad. The brake disc is approximately centered on the first axis of rotations. Means for axially separating the first block from the second block are disposed therebetween. The means are responsive to a rotative force against the second block in a direction which would induce rotation about the first axis of rotation. The means thereby axially separates the first friction pad and the second friction pad, in turn releasing the brake disc.

Abstract: A device for holding a workpiece or part in a desired position. The device has a platen with a stop, a threaded shank actuator and a sliding clamping member. The actuator has a tapered head which engages an inner bearing surface of the sliding clamping member to simultaneously apply clamping forces against a workpiece and securing forces to anchor the sliding clamp member to the platen. A spring element joined to the clamping member retracts the clamping member away from the workpiece.

Abstract: A cam clamp includes a swing clamp arm and multiple options for driving the clamp. The movement of a locking cam within a clamp header influences a central shaft having a clamp member attached thereto to rotate from a first rest position to a second clamping position, then causes the central shaft (with the clamp member mounted thereon) to move axially downwards to exert a clamping force. In a second embodiment, the rotational movement of a locking ring causes a central shaft, having a clamp member attached thereto, to rotate with it from a first rest position to a second clamping position. At the second position, the shaft is restrained from further rotation, but the locking ring continues as before. An appropriately inclined upper surface of the locking ring comes into sliding contact beneath the clamp member, causing the clamp member to pivot downwards with steadily increasing clamping force.

Abstract: An apparatus for gripping a pipe, which apparatus comprises an outer member having a first inclined inner surface, and an inner member having a first inclined outer surface, the arrangement being such that, in use, on rotation of said outer member relative to said inner member in one sense said first inclined inner surface co-operates with said first inclined outer surface so that said inner member moves towards a pipe to be gripped.

Abstract: A mechanical clamping device adapted to engage and secure the upper tooling of a welding knee. The clamping device is motor driven such that several clamping devices can be simultaneously and synchronously operated to engage, align and secure the upper tooling from a remote location. The clamping device includes a clamping lever actuated by a cam mechanism. The clamping lever has an upper end provided with a cam follower, a lower engagement end for engaging the tooling, and a journalling region. The engagement end is adapted to closely engage a corresponding feature on the tooling. The journalling region of the clamping lever is slidably journalled in a bushing which includes a biasing member for biasing the cam follower against the cam mechanism. The clamping lever is pivotably attached by the bushing to the cam mechanism which serves to both rotate the clamping lever and bushing together and stroke the clamping lever within the bushing to secure the upper tooling to the welding knee.

Abstract: A fixture engages each leg of a chair leg assembly to support each leg against longitudinal displacement along respective leg axes. A ram and associated drive member are mounted opposite each leg free end so that each ram axis is substantially aligned with one leg axis. A glide is adapted to fit loosely on the leg free end in a first position and to be driven tightly onto the leg in a second position. A pair of cam arms are coupled to the ram so that as the ram advances toward a leg that has a glide in the first position thereon, the cam arms and jaw members at the free ends of the cam arms, pivot toward the leg. The jaw members cooperate to align the leg axis with the ram axis while the glide is in the first position and to support the leg transversely to the leg axis as the ram advances to drive the glide into the second position.

Abstract: An apparatus for seating and tightening clamps around joints between tubular sections comprises an elongate flexible member such as a chain for extending around a clamp positioned over a joint, the member having rollers spaced along its length, and a tightening device for applying tension to the member to tighten it around the clamp so that the rollers roll around the surface of the clamp and apply a radial force to the clamp.

Abstract: An improved mechanism for automatically clamping a die tool to a press bed or press ram. The automatic die clamp is self-locking and self-compensating to provide a failsafe operation in the clamped position and thus the mechanism retains the clamp in the clamped position. A ramp is provided to guide the movement of a wedge which wedge movement controls the movement of a clamping member. A spring bias may be provided as an optional feature to assist in the self-locking. Release of the clamp requires the application of an external force to overcome the locking of the teeth.

Abstract: A device for compressing a pair of plates composed of a slotted post extending upright from one of the plates, arranged to pass through a port in the second of the plates, and a circular ramp member rotatably attached to the second of said plates, which ramp is positioned to engage the post slot. Upon rotation of the ramp, the post is drawn through the port resulting in a closing of the distance between or compression of the plates.

Abstract: Connector housings (12) are pushed into a succession of nests (26) formed in workholders (17) mounted on an incrementally advanced turntable (15). Subsequent advance of a workhokder from the connector load station causes a cam follower (42) of a spring-biased lever arrangement (37) to react with a cam track (19) to pivot and move locating pins (31 and 32) into holes (13 and 14) formed in the connector housing. Further advance of the turntable (15) causes a cam follower (64) to ride onto a high portion of a cam track (21) to pivot a second lever arrangement (37) to move a spring-biased, pivotally mounted clamping arm (51) into engagement with the precisely positioned connector housing.
