Two opposing slots are present on the first tubular element that extend inwardly a predetermined distance from the open end. The open end of the first tubular element is sized to receive a first of the jaw elements of the hand screw clamp, wherein the threaded screws of the hand screw clamp pass into the slots. The system also includes a second tubular element having an open end and two opposing slots that extend inwardly a predetermined distance from that open end. The open end of the second tubular element is sized to receive a second of the jaw elements therein.

Abstract: A vise for holding objects wherein the vise includes a vise portion having a pair of engagement jaws mounted on one end of a vise body. An adjusting shell is disposed in coaxial relation about the vise body and in cooperative relationship with the engagement jaws. The adjusting shell is rotatable about the vise body, and rotation of the adjusting shell actuates the engagement jaws between their opened and closed positions. The vise portion can be used in conjunction with a rotary module which is mounted to the other end of the vise body and imparts a rotary motion to the vise body about its central longitudinal axis. The rotary module employs a clutch and brake assembly that is mounted on a rotary spindle and housed within an adjusting shell that is coaxial with the rotary spindle. The adjusting shell is slideable backward and forward relative to the rotary spindle to engage and disengage the brake. When the brake is disengaged, the rotary module can be rotated either clockwise or counter-clockwise.

The clamping apparatus has two clamping members each having an outwardly projecting engagement portion configured to fit securely in the recesses and a clamping mechanism actuable to move the clamping members and their engagement portions toward and away from one another for clamping movement along a clamping line coinciding with the imaginary line perpendicular to the intended joint line. The clamping apparatus may be used in forming virtually any edgewise abutting joint between respective structural members, e.g., miter joints, butt joints, linear edge joints, and radius edge joints.

Abstract: A hand screw clamp includes first and second jaws and a pair of threaded rods, each having a handle for manual rotation. Two first couplers are mounted to the first jaw and coupled to the threaded rods, and two releasable couplers are mounted to the second jaw and coupled to the threaded rods. The releasable couplers each include a threaded portion engageable with the threaded rods and a slidable portion sized to accommodate sliding movement of the threaded rods. A push plate is movably mounted to the second jaw and engaged with both of the releasable couplers. This push plate is movable between a first position, in which both of the threaded portions are engaged with the rods and manual rotation of the handles moves the second jaw along the threaded rods, and a second position, in which both of the threaded portions are disengaged from the threaded rods and the threaded rods are free to slide past the slidable portions without rotation of the threaded rods.

Abstract: A workbench of saw-horse height has its top formed by a pair of longitudinally extending top members which form a working surface and which are carried by transverse supports. One of the top members is fixed with respect to the supports but the other is horizontally movable towards and away from the fixed top member to form a vice between the opposed vertical faces of the top members. Adjacent each end the top members are interconnected by screw threaded rods which are restrained against axial movement at their ends adjacent the fixed top members but which are received in nuts connected to the movable top member. The connection of the nut to the movable top member allows independent operation of the screw threaded rods to permit the gap between the vertical faces to be greater at one end than at the other.
