ABSTRACT:
A wedge-shaped brake mounted within a clevis of a swivel caster precludes rectilinear motion as well as swivel motion when engaged. Engagement of the brake is effected by the use of a pedal or lever and when not in its locking position, the brake remains removed from the caster wheel surface. The frictionally engaged brake increases the distance between the caster support or clevis and the axle of the wheel to remove or take up all tolerances in one direction eliminating all movement through caster parts. Several alternative brake-engaging mechanisms are disclosed.
