Antifriction Clasp. (open access)

Antifriction Clasp.

Patent for a new and improved anti-friction clasp. This design "is to provide means whereby the wear due to the rubbing of inclosed rods or ropes against an inclosing casing may be reduced to a minimum and whereby the central alignment of the rods or ropes with respect to the inclosing casing may be accurately preserved" (lines 11-17). It consists in "a series of friction balls or rollers mounted therein and projecting from the periphery thereof and being divided into sections adapted to be clamped at any point around the rod or rope" (lines 97-101).
