Abstract
A retainer for the nose piece of the shoe which backs the abrasive belt in a belt-type grinding machine. The nose piece is T-shaped having a cross member provided with opposite side portions and a stem between the side portions. The head of the shoe has a stem-receiving recess and outwardly facing locating shoulders on opposite sides of the recess. The nose piece is mounted on the head with its stem in the recess and its side portions overlying the shoulders. The retainer is a pin having a resilient shank provided with an offset which may be either a laterally bent portion of the shank or a cam-like projection on the shank. The pin is received in aligned openings in the head and in the stem. When rotated to locking position, the pin offset forces the stem down into the recess and also forces the side portions of the cross member down squarely and solidly upon the shoulders.
