Abstract: A height gage is disclosed including a vertical column of circular cross section with a carriage that rides up and down the column. The carriage is maintained in fixed radial position relative to the column by a longitudinal groove in the column into which a longitudinal surface is formed that extends accurately on a radius of the column throughout the length of the column. A shoe which is mounted on the carriage engages this vertical surface and maintains the carriage always in proper alignment. Means are also provided on the column and the carriage to measure the position of the carriage on the column.

Abstract: The invention relates to a machine tool of the type having a rotatable support for the material to be worked upon and a slide movable toward the work carrying a programmed turret with a plurality of tool supports which may be indexed to position one tool at a time for operation on the work and more particularly to mounting of the tool turret for indexing with torsional stiffness and for recessing of the work radially of its axis of rotation by a hydraulic means while maintaining torsional stiffness.

Abstract: This invention relates to a height gage of a type to be attached to a digital readout and in which a source of air under pressure is utilized for providing anti-friction means for moving a slide which carries a tool for measuring distance.

Abstract: A linear motion ball bearing assembly is provided for mounting within a housing and comprises a plurality of ball retainer members with a raceway therein. With the members surrounding a shaft, a load bearing plate is associated with the load bearing portion of each raceway and on the outer periphery of each raceway an elastomeric strip of material is mounted to resiliently restrain the movement of the ball bearing assembly in the spherical seat within the housing, and provide a high damping factor and exhibit high static stiffness.

Abstract: A pillow block for the reception of self-aligning linear motion bearings which pillow block can be made up of two or more self-aligning bearing units which will allow increased bearing surface with an ease of alignment.

Abstract: This invention relates to a clutch tooth design which provides increased load carrying ability by having substantial face to face contact of the teeth during a partial engagement of the clutch teeth. The teeth of the clutch are machined to a profile form which is of exponential shape. Mating contact areas lie in a mid-pitch plane perpendicular to the axis of rotation of the clutch. The mutual tangent between two contacting teeth lies in a truly helicoid surface. The essential line contacts resulting from machining are converted by a coining process to areas large enough to carry the service loads. As a result the tooth form developed actually improves with continued use.
