    Abstract: The rail clamp includes a carriage having an actuator frame mounted to its base so as to extend upwardly from the base. Springs are mounted in the actuator frame at the upper end of the carnage. An actuator is mounted between the base and the springs. A wheel is mounted on a wheel support. The wheel engages the rail. At least one suspension frame is pivotally mounted to the carriage and at an opposite end, to the wheel support. The actuator operates on the suspension frame so as to elevate the carriage. A pair of clamping levers is pivotally mounted to the base of the carriage. Brake shoes mount on the lower-most ends of the levers. The levers are pivotable so as to clamp their lower-most ends together when their upper ends are moved apart.

    Abstract: The present invention provides a releasable skate retarder for railway cars. The retarder includes a plurality of spring packs including springs which bias shoe carrying beams toward running rails, trapping wheels of a railway car entering the retarder between the shoes and the running rails, and applying a frictional force to the railway car wheels for stopping the railway car and retaining the railway car in the retarder. The retarder is operable in a release mode in which an operating mechanism moves the shoe beams to a release position in which the spring force is released, allowing the railway car to move freely through the retarder. The retarder is operable in a service mode in which the operating mechanism moves the shoe beams outwardly, allowing the insertion of shims which cause the shoes to be repositioned closer to the running rails to compensate for shoe wear. In one embodiment, the operating mechanism includes a plurality of rams and a common operating member which couples the rams to the spring packs, for drawing the shoe beams inwardly when operating in the release mode and for pushing the spring packs outwardly when operating in the service mode.

    Abstract: Apparatus for preventing runaway of trolleys in a power-and-free conveyor system that includes a friction bar that extends lengthwise of the free conveyor track on a side of the track remote from the power conveyor for motion lengthwise of the track at an acute angle to the direction of motion of the trolleys along the track. The friction bar is releasably biased laterally outwardly from the track and in a direction lengthwise of the track opposed to the direction of trolley motion on the track so that trolleys may travel freely along the free conveyor track past the bar. In the event that a trolley is traveling at excessive velocity along the tree conveyor track, the friction bar is moved in the direction of motion of the trolley and at the acute angle laterally into a position for frictional engagement with the trolley on the track, such that momentum of the trolley cooperates with frictional engagement of the bar with the trolley to wedge the bar against the trolley and arrest motion of the trolley on the track. Thus, momentum of the trolley along the track cooperates with angulated motion of the bar into frictional engagement with the trolley for automatically and inherently increasing frictional forces that arrest motion of the trolley on the track.

    Abstract: A marshalling yard retarder includes a mechanical braking means with elongated braking members on both sides of the rail movable towards and from the vertical plane of the rail to engage against a wheel rolling on the rail. The braking members are pivoted about horizontal axes and are actuated by hydraulic pistons which are flexibly mounted. The cylinders are supplied by a supply conduit containing a nonreturn valve and a return conduit having a pressure-limiting overflow member which is connected to a storage tank from which the pressure medium is drawn. There may be two pressure-limiting overflow members set for different pressures, and a weighing means for selectively connecting these members to the return line.
