ABSTRACT:
An improved brake mechanism for use with roller conveyors is provided. The brake mechanism comprises a brake plate, a brake shoe and a jack mechanism for biasing the brake plate and shoe into and out of braking orientation with conveyor rollers. The brake plate is generally flat and has two rigid extensions thereon. The brake shoe is a resilient, or elastic, loop of material which is stretched between the brake plate extensions and which is securely held thereon by resiliency of the brake shoe material. The brake shoe may be rapidly and easily mounted upon, or removed from, the brake plate without the use of special tools. Preferably, the brake shoe is manufactured from surgical tubing, which generally possesses sufficient resiliency for the application and which has a high enough coefficient of friction to be effective in braking conventional conveyor rollers.
