Abstract: A clamp assembly including a flexible restraining element having a first end and a second end, the flexible restraining element receivable about an irregularly-shaped item carried upon a work surface, a brace for engaging the first end of the flexible restraining element to the work surface and a coupler for engaging the second end of the flexible restraining element to the work surface and for adjusting the flexible restraining element about the irregularly-shaped item for clamping the irregularly-shaped item to the work surface.

Abstract: The disclosure relates to a tooling set up and subplate means for machine tools wherein a subplate is provided with intersecting rows of openings; said rows precisely intersecting each other at right angles and some of said openings having precision locating bushings therein and others of said fixture openings being internally screwthreaded fixture openings. The locating openings are in rows adapted to be precisely aligned with the two axes of movement of the machine tool table and hold down means adapted to secure said subplate on the machine tool table and tooling members having fixture receiving openings and locating openings adapted to coincide with the respective openings in said subplate so as to precisely align tooling with the movement axes of a machine tool and to thereby alleviate the time usually devoted to the alignment of a piece of work on a machine tool with respect to its directions of movement.

Abstract: The disclosure relates to a torque limiting vise for holding work on a machine tool table. The vise has a pair of relatively adjustable jaws between which parts may be clamped and held on a machine tool table and one of the jaws of the vise is advanced toward the other one by means of screwthreaded means having torque limiting means adapted to limit the torque of the screwthreaded means to a predetermined amount so as to limit the clamping force between the jaws to a predetermined amount, and thereby to limit mechanical deflection of the jaws to a predetermined amount so that each time a part is clamped between the jaws, the amount of deflection of the jaws is repeated and thereby permitting repeated machining operations with precisely the same holding position of the part between the jaws as it may relate to a cutting tool spindle axis of the machine tool upon which the vise is used.
