A clamp to retain a block of material on a machining table including a body having a first face, a first front face oriented toward the machining table and the block of material when in use, a nose projecting relative to the first front face having a second front face parallel to the first front face, first and second edges connecting the first and second front faces, and at least one internally threaded hole opening at least partly at the level of the second front face with an axis forming a non-zero angle with the first face and the second front face, at least one grub screw screwed into the internally threaded hole having a pointed free end configured to penetrate into the block of material when in use when screwing in the grub screw, and a connecting system to demountably connect the clamp to the machining table.

A clamp assembly that may be used for securing to a raised portion of a surface. The clamp assembly comprising a mounting body of a general block shape having a slot for receiving the raised portion formed in a bottom surface of the mounting body attaching the clamp assembly thereto. The clamp assembly is configured with one or more pins that may be formed in a substantially elongated cylindrical shape. The pins may be configured to be received in one or more push-pin holes formed in the mounting body, whereby the push-pin holes extend to the slot from a side surface of push-pin holes. The clamp assembly includes a fastening element adapted to be received in a fastener hole formed adjacent the push-pin holes in the side surface of the mounting body. The fastening element is configured to secure, attach and hold the clamp assembly to the standing seam by forcing the pins against the raised portion of the surface disposed in the slot.

An optical device may include an optic disposed in an optical path. The optical device may include a mount to dispose the optic in the optical path. The optical device may include a plurality of spring clamps to attach the optic to the mount. The spring clamp, of the plurality of spring clamps, may include a body, a spring, and a screw. The screw may be to attach to the mount and to compress the spring. The spring may be to dispose a leading edge of the body against the optic. The spring clamp may be to maintain the optic in the optical path for a thermal cycle of at least between approximately 50 C. and approximately 130 C.

A method and tool assembly (10) for unloading and reloading spring energy from a torsion bar (11) in a torsion bar suspension system of a motor vehicle. The tool assembly (10) includes a generally C-shaped body (14) having a screw shaft (24) threaded through a boss (22) in a lower section (18) thereof. An anti-rotation stem (38) includes a knurled flat face (40) which increases versatility of the tool assembly (10) by enabling anti-slip operation with various vehicle types. A counter-torque tool perch (46) extends from the lower section (18) of the tool body (14) for applying a counter-rotational torque to the body (14) during use of the tool assembly (10).

A clamping device includes a first, a second clamping member, a first, a second connecting rod, and an elastic member. The first clamping member includes a first side and a second side opposite to each other. The second clamping member includes a third side and a fourth side opposite to each other. The first connecting rod is pivotally disposed between the first side and the third side. The second connecting rod is pivotally disposed between the second side and the fourth side. The elastic member is connected between the third side and the first connecting rod. The elastic member provides a restoring force to make the first connecting rod rotate relative to the second clamping member, to drive the second connecting rod and the first clamping member to rotate, so that a distance between the first and the second clamping member is shortened to clamp an object.

A solid surface clamp that has a top jaw and a bottom jaw, along with alignment structures, is disclosed. The clamp includes a top jaw, a bottom jaw, a bolt attached to the bottom jaw and slideably received through the top jaw, and a nut. The bolt has an alignment cutout, a threaded portion extending from the top jaw and defines a bolt longitudinal axis. The nut is threaded onto the threaded portion of the bolt and transitions the clamp from an open position to a clamping position. The top jaw further includes an alignment hole that contacts the alignment cutout and maintains the top jaw and the bottom jaw substantially fixed relative to each other about the bolt longitudinal axis. The alignment cutout moves relative to the alignment shaft in the direction of the bolt longitudinal axis when the clamp transitions from an open position to a clamping position.
