Abstract
A conveyor roller brake that is preferably carried within the confines of a conveyor roller and includes a friction surface carried by the conveyor roller and a brake shoe that is maintained continuously in biased engagement with the friction surface and is selectively engageable for disengageable with respect to a nonrotatable hub element thereby selectively permitting the brake shoe to rotate freely with the conveyor roller in frictional engagement with the friction surface, or to be arrested in its rotation so that relative rotation of the roller with respect thereto provides continuous roller braking through frictional sliding of the brake shoe in biased engagement with the friction surface.
