The present invention relates to a device and a method associated with the device. With respect to the device, it is a work holding and clamping device, which increases the usable span to almost twice its stored length. This device has an inner and outer assembly. The inner and outer assemblies are nested or telescopic. Each assembly is made of a square or rectangular tube that has a jaw affixed to one end. The inner assembly contains a locking mechanism to allow for length adjustment. When arranged so that the jaws are on the same side of the respective assemblies, the clamp is capable of a span that is almost equal to the length of the inner assembly. When arranged so that the jaws are on opposite sides of the respective assemblies, the clamp is capable of a span that is almost equal to the sum of the length of the inner assembly and outer assembly.

An air chuck includes: a finger support part including a pair of fingers and a pair of lock shafts; a chuck main body part including an operation mechanism operable to open and close the fingers; and linking mechanisms that detachably link the finger support part to the chuck main body part. Each of the linking mechanisms causes the corresponding lock shaft to shift to a non-lock position so as to render the pair of fingers capable of being opened and closed when the finger support part is linked to the chuck main body part. Each of the linking mechanisms causes the corresponding lock shaft to shift to a lock position and locks the pair of fingers so as to render the pair of fingers incapable of being opened and closed when the finger support part is detached from the chuck main body part.

A locking assembly for locking a portable electronic device to a work surface. The locking assembly comprises a clamp assembly including an elongated bar that extends between a first end and a second end. The clamp assembly further includes a first jaw and a second jaw moveable along the elongated bar for clamping to a work surface between the first and second jaws. A connector extends from a first connector end that is pivotally connected to the locking assembly to a second end that can be connected to the portable electronic device. The connector securing the portable electronic device to the work surface while permitting it to pivot with respect to the locking assembly.

Certain exemplary embodiments can provide a system that comprises a bar and a pair of clamps. The bar defines a set of spaced apertures. The pair of clamps comprises a first clamp and a second clamp. Each of the first clamp and the second clamp comprises a first portion and a second portion.

The present invention relates to a straight edge clamp that has a clamping head assembly and a stop assembly mounted upon the body of the straight edge. The head and stop are not connected together and the stop assembly is free to move with respect to the head assembly. The stop assembly has a locking assembly that allows it to be locked to the straight edge. The straight edge clamp body can include sections that are adapted to be connected together to form the overall length of the straight edge clamp.

The current invention relates to jig apparatus which is provided of a form to allow accurate positioning and repositioning of the same with respect to workpiece and the use of the jig apparatus to provide a guide for the provision of a drill bit through at least one guide passages therein to form a hole in the workpiece at a required location. In one embodiment the jig apparatus is provided in a form so as to provide a plurality of passages, each of which can be used as a guide for a drill bit to thereby allow a plurality of spaced apart drill holes to be formed in the workpiece without the need to move the jig apparatus with respect to the workpiece. In one embodiment guide means are provided which are selectively positionable by the user in order to allow the position of the jig apparatus with respect to the workpiece to be accurately defined and retained by the user.

An apparatus for applying pressure to at least a portion of an edge surface, which bridges opposing faces of a workpiece, comprises a frame, a first roller, a second roller, a rotation-control member, a first biasing member, and a second biasing member. The first roller and the second roller are coupled to the frame, are rotatable relative to the frame, and are translationally fixed relative to the frame. The rotation-control member is movable relative to the frame, controlling rotation of the first roller and the second roller relative to the frame. The first biasing member is configured to operate in compression along a second axis. The second biasing member is positioned, in compression, between the frame and the rotation-control member.

The present disclosure is related to a hold-down for a cable tray. The hold-down may be configured for high-wind situations. The hold-down includes a support clamp for clamping onto a support, and a hold-down arm for holding the cable tray on the support.

An apparatus for applying pressure to at least a portion of an edge surface, which bridges opposing faces of a workpiece, comprises a frame, a first roller, a second roller, a rotation-control member, a first biasing member, and a second biasing member. The first roller and the second roller are coupled to the frame and are rotatable relative to the frame. At least one of the first roller or the second roller is translatable relative to the frame along a first axis. The rotation-control member is movable relative to the frame, controlling rotation of the first roller and the second roller relative to the frame. The first biasing member is configured to operate in compression along a second axis. The second biasing member is positioned, in compression, between the frame and the rotation-control member.
