ABSTRACT:
A caster wherein an upright stub carries a swivel bearing for an inverted U-shaped frame having legs which support the shaft for a wheel. The shaft is movable sideways in elongated horizontal slots of the legs in response to depression or lifting of a pedal which is pivotably connected to the legs. The pedal has two arms which flank the legs of the frame and are provided with substantially S-shaped slots crossing the slots of the adjacent legs and receiving portions of the shaft. When the pedal is depressed, the wheel frictionally engages and displaces a plate-like brake member which is vertically movably mounted in the legs of the frame and can be moved into direct frictional engagement with that part of the bearing which is non-rotatably connected to the stub. Alternatively, the plate-like brake member can be moved into direct frictional engagement with bolts which secure the web of the frame to one race of the bearing whereby the brake member displaces a pin which is reciprocably mounted in the web and in the one race and moves into frictional engagement with another race which is rigid with the stub.
