Abstract: A vise with a sliding head which slides on an elongate body. A diagonal clamping screw passes through a hole in the sliding head and is threaded into a pin inserted in an internal sliding block. The internal sliding block has a toothed pattern which is able to interlock with a toothed pattern fixed to the body underneath the vise slides. The diagonal clamping screw provides force to lock the tooth patterns together and pull the head forward when tightened. A spring provides force to disengage the internal sliding block teeth and fixed teeth on the body when the diagonal clamping screw is loosened.

Abstract: A first threaded member (11) is supported by a housing (3) so as to be rotatable about its axis and to be unable to axially advance and retreat. While a second threaded member (22) is threadably engaged with the first threaded member (11) so as to be able to axially advance and retreat, the second threaded member (22) is supported by the housing (3) under the condition that its rotation about its axis is preventable. Under a clamping condition, the second threaded member (22) is strongly tightened by the first threaded member (11) which has been rotated by an impact wrench (16). Thereby, a metal mold (6) is fixedly pressed by a clamping member (5). When changing over from the clamping condition to an unclamping condition, large counterclockwise impacts are intermittently imposed to the first threaded member (11) by the wrench (16). Thereupon, the first threaded member (11) is rotated counterclockwise little by little by those impacts.

Abstract: A railvice for use with a wire EDM, milling machine, or boring machine, having an elongated rail through which a T-slot extends longitudinally. A locking member of the railvice sits in the T-slot. A jaw element of the railvice connected to the locking member by a bolt includes a cavity for the locking member. The locking member has bias forces acting upon it to force the locking member towards the bottom of the T-slot as well as along the T-slot. The bolt externally anchored with respect to the locking member is rotated to cause the bias forces acting on the locking member to assist in either locking the locking member in the T-slot or forcing the locking member to the bottom of the T-slot for movement of the railvice along the T-slot.

Abstract: An improved clamp assembly includes a first clamp jaw having a plurality of incremental teeth on a lower surface which selectively mate with teeth on a clamp body. The teeth on the first clamp jaw end at one end at a tooth root and at the other end on an incline beyond and above the predetermined location of a tooth root. In this way, the first clamp jaw may be reversed to provide fine control over the incremental adjustable position of the first clamp jaw relative to the clamp body. In another feature of the present invention the other clamp jaw is a wedge-type clamp jaw having a threaded member with two enlarged portions received in a bore in the clamp jaw. The enlarged portions ensure that the threaded member is effective to move the wedge clamp jaw upwardly and downwardly relative to the clamp body. This is an improvement over prior art wedge-type clamp jaws which required complicated spring arrangements.
