Abstract
An automatic regulator for an internally expanding drum brake capable of automatically controlling the amount of play or ineffective stroke of a brake wire to a predetermined value so that an intended braking effect can be always produced with a definite stroke of the brake wire irrespective of wear on the linings of brake shoes or permanent expansion of the brake wire. A brake lever is operatinely connected with the brake shoes housed in a brake drum so that the brake lever is pivoted by operation of the brake wire to outwardly expand the brake shoes to place the shoe linings into frictional engagement with a brake surface of the brake drum. The return angle of the brake lever upon a brake releasing operation is rendered constant by a stopper mechanism. The brake wire comprises an inner wire member connected to the brake lever, and an outer wire member slidably fitted over the inner member and urged by a compression spring in a direction away from the brake lever. The outer wire member is moved relative to the inner wire member to take up slack therebetween due to increased wear on the shoe linings or permanent expansion of the brake wire in response to a brake applying or releasing operation.
