Abstract
A caster assembly of the type that accommodates swivelling movement of the caster wheel including a U-shaped horn that flanks the sides of a soft tread and supports a wheel axle. A swivel plate is mounted at the top of the horn, adapted to be connected to the underside of the article to be supported, and it carries a pin that extends through the horn and has an annular toothed swivel lock plate at its lower end. A unitary swivel lock and brake member is reciprocably mounted on spaced rearwardly projecting horn ears and has serrations at its top defining teeth that engage the swivel lock plate teeth to lock the horn with respect to the swivel plate. The lower end of the swivel lock and brake member has an arcuate brake shoe that bites into the soft tread of the outer surface of the wheel to effect braking. A pivotally mounted foot-operated actuator is carried by the horn adjacent the swivel lock and brake member and it has cam surfaces that engage and shift the swivel lock and brake member laterally to substantially simultaneously effect both swivel lock and braking functions.
