A caster brake assembly simultaneously brakes separate caster wheels, one swiveling and one non-swiveling, of a movable caster-wheel supported article. It includes a bracket mounted to the bottom of the article, a longitudingal frame assembly vertically slidably mounted to the bracket, brake shoes mounted at the ends of the frame assembly, and a cam member pivotably mounted to the frame assembly and operable against the bracket to force the frame assembly downward relative to the bracket and to brakingly engage the brake shoes against the wheels.

A caster brake assembly for simultaneously braking ground engaging caster wheels separately mounted on a vehicle, comprising: a bracket rigidly mounted to the vehicle between the wheels and having a first downwardly extending plate; a longitudinal frame assembly extending between the wheels and being slidably mounted to the plate for planar motion parallel to the plate; brake shoes rigidly attached at ends of said frame assembly; guide means, connected to said frame assembly and said bracket, for guiding the movement of said frame assembly along only one linear direction relative to said bracket; a cam member pivotably mounted to one of said frame assembly and said bracket such that pivoting of said cam member against the other of said frame assembly and said bracket causes said frame assembly to move relative to said bracket and causes said brake shoes to simultaneously engage both wheels; and, spring means, mounted between said bracket and said frame assembly, for urging said frame assembly and said brake shoes away from the wheels; said frame assembly including a pair of opposing parallel walls defining a cavity for sliding receipt of the plate therebetween and wherein said cam member is pivotally mounted to said frame assembly within said cavity for cam engagement against said bracket.
