Abstract: Rings and travelers such as for use on spinning frames and the like are provided with the improvement of a coating on the respective surfaces thereof, the coating being chemically deposited onto the surfaces and being uniform in thickness about each surface, the uniform thickness of the coating on each surface ranging from about 0.1 mil to about 0.5 mil, the coating including from about 15% to about 30% by volume of a particulate polymeric fluorocarbon, preferably polytetrafluoro-ethylene, dispersed in a metallic matrix which is preferably a nickel-phosphorus alloy matrix.

Abstract: An improved ratcheting tool has a driven shank rotatably supported fore and aft in the ratchet housing. A reduced-diameter rearwardly-extending portion of the driven shank passes through a central recess in a pivotable cam shifter and is rotatably piloted in a closed cylindrical recess. This recess is formed in the ratchet housing rearwardly of a blind axial bore within which the driven shank is disposed. An intermediate portion of the driven shank is rotatably journaled in the inner annular bearing surface of a collar; and the collar is press-fitted within a counterbore forwardly of a ratchet on the driven shank, thereby retaining the driven shank in the ratchet housing.

Abstract: A ratcheting tool has a handle mounted on a ratchet housing. The ratchet housing has a blind axial bore formed therein. A driven shank has a rearward portion nested partially in the bore, and a ratchet is formed externally on the rearward portion of the shank. A cam is seated in the bore, rearwardly of the ratchet, and is pivotable substantially about the axis of the bore. The cam has a bore formed therein, and a thrust ball is seated in the cam bore axially between the bottom of the blind axial bore in the ratchet housing and the rearward portion of the shank, thereby accommodating axial thrust loads on the tool. A selector pin is carried by the cam and extends radially therefrom through an arcuate slot in the ratchet housing. A pair of L-shaped pawls are alternately actuated by the cam. The pawls have respective leg portions extending forwardly to engage the ratchet, thereby alternately keying the ratchet to the ratchet housing.
