Abstract
An automatic application hand brake mechanism is provided for automatically applying at least one brake member secured to a railway vehicle with the hand brake assembly. The mechanism comprises an operating member having at least one ratchet engageable with at least one gear of the hand brake assembly for operating the gear assembly in a direction which will cause an application of the at least one brake member. The apparatus also includes an application cylinder and a drive arm extending from an end thereof having a first portion which is connected to the operating member. The drive arm is capable of reciprocating with respect to the application cylinder upon the application of a force thereto to supply a predetermined pressure to the operating member to cause an automatic application of the at least one brake member.
