Abstract
A pulley guard is arranged for mounting to an interior surface of projecting flanges mounting an associated pulley structure, wherein arcuate discs are arranged in confrontation in an edge-to-edge relationship with outer edges of the first and second pulley flanges to prevent the binding and abrasion of a pulley belt preventing slippage relative to an associated pulley.

A pulley guard apparatus, comprising,
- a pulley wheel, the pulley wheel including a pulley groove circumferentially directed about the wheel, including a first annular side flange and a second annular side flange spaced relative to one another on opposed sides of the groove, and
- a first frameplate mounted to a first side of the pulley wheel, and a second frameplate mounted to a second side of the pulley wheel, with a first frameplate flange disc mounted to the first frameplate extending beyond the first side flange, and a second frameplate flange disc mounted to the second frameplate extending beyond the second side flange mounted to the second side flange, wherein a first frameplate flange disc and a second frameplate flange disc define an obtuse angle therebetween and includes a first frameplate flange disc interior surface and a second frameplate flange disc interior surface in confrontation relative to one another, and
- a first arcuate insert disc contiguously and coextensively mounted to the first frameplate flange disc interior surface, and a second arcuate insert disc in contiguous and coextensive relationship relative to the second frameplate flange disc interior surface.
