ABSTRACT:
Spring-biased longitudinally movable pin means are mounted to be engageable with circumferentially spaced recesses around the inside faces of non-pivoting casters that are, in turn, positioned under the mid-portion of a rollable service cart so as to provide for an automatic braking system for such cart. Cam means provided to retract the springbiased braking pins from the caster recesses and manually operated linkage means extending from each end of the cart to connect to said cam means provide for a cart operator stationed at either end of the cart to release the braking system and thereby permit movement of the cart.
