Abstract: A caster brake construction comprising a base, a fork rotatably mounted on the base and having downwardly extending legs, an axle extending between the legs, and a wheel rotatably mounted on the axle. A washer is non-rotatably mounted on the axle exteriorly of one of the legs. A pedal is mounted on the axle exteriorly of the washer and has circumferentially spaced arcuate cam ways. Each cam way is tapered inwardly toward the center thereof and a plurality of circumferentially spaced projections on the washer normally engaging the deepest portions of the cam ways such that when the pedal is rotated in either direction from said normal position, the cam ways force the projections axially inwardly thereby forcing the one leg against the wheel to lock the wheel against rotation, and when the pedal is returned to its original position, the braking force is relieved.

Abstract: A caster swivel lock construction comprising a base, a yoke rotatably mounted on the base for rotation about a vertical axis and having a ring plate and spaced legs extending away from the ring plate, an axle extending between the legs and a wheel rotatably mounted on the axle. The ring plate has one or more radially extending notches therein. A spring loaded plunger assembly is mounted on the base and comprises a body, a plunger movable axially in the body, and a spring associated with the plunger. A foot pad is pivoted to the plunger on the other end and has a cam portion urged by the spring to engage a portion of the body so that the plunger is moved axially inwardly and outwardly by operation of the foot pad. The plunger assembly is removably mounted on the base so that the plunger axis extends radially inwardly toward the ring plate and movement of the foot pad causes the plunger to move radially inwardly and outwardly for engagement and disengagement with a notch.
