Abstract: A wear compensating, precision, linear slide assembly comprises a slide support having a base and an elongate guide rail. The rail has flat longitudinal exterior side walls convergently inclined toward the base and a slide has a guide rail receiving slot with flat longitudinal side walls convergently inclined toward the rail base. The transverse width of the slot is greater than the transverse width of the rail to define a longitudinal space between one side wall of the rail and one of the side walls of the slide. An elongate gib is received within the space and has divergent side walls mating with the side walls of the slide and guide rail. At least one end cap fixed to the slide has a cam part opposite one end of the gib and a cam part on the gib is cooperable therewith to urge the gib to automatically wedge between the guide rail and slide in a direction away from the base as permitted by wear.

Abstract: An automatically compensating gib assembly includes spring loaded pins resiliently biased outwardly from longitudinal bores at each end of a movable gib element. End caps fixedly mounted at each end of a mating fixed gib element are provided with enlarged conical bores which present a downwardly inclined surface against which the spring loaded pins is urged to thus resiliently bias the movable gib downwardly relative to the fixed gib to automatically compensate for side loading variations in a slide assembly.

Abstract: A tool positioning device for radially adjusting, by remote control, the position of a cutting tool very precisely relative to the axis of rotation of a rotating face plate includes an air pressure operated bi-directional pawl and ratchet mechanism employed to operate a differential screw to shift a tool carrying member radially of the face plate.

Abstract: A micrometrically adjusted tool arm assembly for mounting on a spindle or a non-rotating support has a tool arm with a mount thereon for generally centrally supporting a tool bar. Only the end sections of the arm are secured to a base support and a slot system extends axially through the arm so that the central section can move radially relative to the ends of the arm. A micrometrically adjustable positioner mechanism engages the central section in a position relative to the slot system to provide a rigid backup for the tool bar. When the assembly is mounted on a spindle a releasable lock is provided which functions to deform the slot system and move the central section radially to engage positioner mechanism at a preselected position.

Abstract: A tool arm assembly adapted to be supported on a machine tool adjacent a workpiece rotating spindle has a tool carrier mount on a flexible, deformable portion; a bi-directional actuator for operating manually adjustable motion transmission means is operated by a remotely controlled motor device which normally is out of operating engagement with the actuator so that the motion transmission means can be adjusted manually.
