Curated summary
US patent 5,253,736 to Tec Tran Corporation. A railway brake actuator provides both service and parking braking from a cylinder in which spring stacks including disc springs store energy: hydraulic pressure disengages a clutch to enable spring retraction of the piston, and a gripper ring limits retraction to provide slack. The specification describes spring energy storage, hydraulic control and slack adjustment — patent reference for railway spring brake actuator design.
