Abstract: A multi-position fixture assembly comprising a captive body having a threaded end unitary with an enlarged end. The threaded end is adapted to threadably attach to an object to be lifted. The enlarged end of the captive body includes a swivel cavity and external hex head. The swivel cavity has a generally flat bottom and a generally cylindrical side wall. The hex head is easily engaged by a conventional wrench to torque the fixture to a workpiece. The cylindrical side wall of the swivel cavity includes an internally threaded portion which is opposed from the bottom. A hoist head with a flanged end and an opposed free end is assembled into the swivel cavity of the enlarged end of the captive body by means of an externally threaded retainer ring. The retainer does not bear on the flanged end so the flanged end is retained for free rotation inside the swivel cavity. Thusly retained, it is free to swivel through a 360 degree arc. A lifting loop is mounted to the free end of the hoist head.

Abstract: The invention is directed to targets for use where precise alignment and location measurements on an object is required. Several embodiments of the invention are described. The targets have at least a portion of their outer surface curvilinear. The target is supported on a convex supporting surface on a support body. Various configured single targets and multiple targets are described for use on flat as well as curved surfaces. Some of the targets have either non-reflective or reflective target surfaces. The various embodiments of the ball targets are used in conjunction with either optical or laser theodolites or the like to preform the required location measurements.

Abstract: A removable and replaceable insert locating pin adapted to locate a workpiece in a tooling fixture for machining thereof. The locating pin includes a central body inserted in a precisely located aperture in the tooling fixture and an upper portion that extends into an aperture in the workpiece. Hardened inserts are selectively positioned in apertures formed in the outer periphery of the upper portion and contact the sidewall of the aperture in the workpiece for positioning the workpiece on the sub-plate in a desired direction or directions. Flexibility of the set up of the tooling for machining of workpiece is enhanced.

Abstract: An indexing and locating component to be used with a fixture for precision machining of parts. The component includes a receiver bushing press fitted into a fixture and a locating pin which is adjustable rotationally as well as vertically. A lock nut locks the pin in a predetermined position and permits removal and replacement of the pin with another pin having another configuration. Locating pins of various configurations are shown.

Abstract: A removable and replaceable locating pin adapted to locate a workpiece on a tooling fixture for machining thereof. The locating pin includes a locator pin having various illustrated configurations is adapted to cooperate with a workpiece for positioning the workpiece in various directions of restraint. The locating pin is provided with manually actuatable locking means that permits easy adjustment or removal of the specific locator pin as a particular machining operation may require. Flexibility of the set up of the tooling for machining of a workpiece is enhanced.
