ABSTRACT:
A lock-out apparatus for shock absorbing draft gear on a railway car which draft gear has a housing adapted to be fixed to one end of the railway car, a shock absorber is provided in the housing to cushion shock on the coupler of a railway car at the one end. The shock absorber includes at least one movable shock absorbing member operatively connected to the coupler and a cushion cooperating with the movable member to cushion shock. The lock-out apparatus has a locking member slidably mounted in the housing for movement between a locking and an unlocking position. There is a fluid motor for moving the locking member, and a conduit connecting the fluid motor to a brake line on the railway car whereby a change in the pressure of the fluid in the brake line will operate the fluid motor to move the locking member to a locking position to prevent movement of the movable shock absorbing member and to thus lock out the draw gear.
