ABSTRACT:
Kinetic energy shock incident to the trip release of the chain under tension of a railway car hand brake mechanism is absorbed by one or more blocks of compressible shock-absorbing solid material or by compressible shock-absorbing spring means located within the housing of the mechanism and in the path of the chain when the brake is tripped or released and the chain is prevented from winding in the wrong direction and consequently damaging the hand brake mechanism at one end of the chain and brake components at the other end of the chain.
