Abstract: An improved stationary refrigeration unit having a cooling compartment and a service compartment is provided for installation in tight quarters for vehicles, the service compartment having an access door on the same side of the unit as the cooling compartment access door, components readily accessible and adjustable through the service compartment door, and an adjustable component mounting assembly rigidly mounted within the service compartment. The adjustable mounting assembly includes a stationary carriage, a mounting member slidably mounted to the stationary carriage, and an assembly longitudinally moving the mounting member and the component attached thereto relative to the stationary carriage.

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.
