摘要： A rail car has a sliding sill located within a fixed frame and a shock absorber for absorbing shock. The shock absorber has a housing with inner and outer chambers containing oil and gas. A piston extends from the housing. The housing has an end plate on its end which engages a frame stop. The housing has a base end which engages another frame stop. Limiting stops formed on the housing limit the amount of buff movement allowed.

摘要： 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.

摘要： This disclosure deals with mounting structure and a spring return assembly for an end-of-car cushioning apparatus of a railway car. The railway car includes a center sill having an opening formed in each vertical side thereof, and the mounting structure includes a casting secured in each opening. A vertical slot is formed in each casting. The apparatus further includes a cushioning unit having lugs formed integrally therewith, and the slots receive the lugs, with the result that the lugs and the castings transfer loads from the unit to the sill. The spring return assembly includes at least one stack or set of compression springs coiled on a rod, the springs being connected to the unit. A tube is positioned over the springs, and the rod and the tube guide the springs. A bushing on the rod prevents the tube from sliding on the springs. The connections in the spring return assembly are loosely made to accommodate shifting of the parts.

摘要： A hydraulic cushion device includes a pair of cylinders having outer closed ends positioned together for reciprocating movement between extended and contracted positions. One of the cylinders includes a piston head having a metering orifice through which a metering pin positioned on the other cylinder is movable, whereby fluid from one side of the piston head is moved to the other side thereby providing fluid cushioning action. An accumulator casing is secured to one end of the metering pin and is relatively slidably disposed in one of the cylinders. The casing includes a floating piston normally retained by means of a spring in a closed position over openings in the casing to close the same. During cushioning action of the unit fluid passes through the openings of the casing to the interior thereof, moving the piston and fluid may be stored within the casing. The piston head includes a valve element cooperating with flutes on the metering pin for by-passing fluid through the piston.

摘要： A cushioning arrangement for railroad cars that is of the ''''end of car'''' cushioning type and includes a hydraulic cylinder keyed to the car fixed center sill against buff and draft forces and having its piston rod secured to a slidably mounted coupler adapter member having flanges projecting from either side of same that each carry a resilient draft impact absorbing cushion that cooperates with fixed draft stops. A compression spring acts between the hydraulic cylinder and the adapter member to bias the ram to its neutral position after a buff stroke, and the adapter member flanges engage over solid buff limiting stops at the end of the buff stroke. The hydraulic cushion includes a combined programmed metering-pressure sensitive orifice and control arrangement that insures needed control over the ram to overcome train line tendencies.

摘要： A hydraulic shock absorber for railroad cars having a first cylindrical member having a closed end and an opened end; a second cylindrical movable member disposed adjacent the opened end of the first member, surrounding the first member, longitudinally movable with respect to the first member and connected to a movable load; a third tubular member disposed within and coaxial of the first member and secured to the second member and a fourth tubular member secured to the closed end of the first member and disposed within and coaxial of the first member extending into and in a slidable non-sealed association with the third member. First and second piston discs are disposed transverse of the first member in a predetermined manner to form a first hydraulic medium chamber between the first and second discs, the interior of the first member and the exterior of the third member and a second hydraulic medium chamber between the second disc, the closed end of the first member, the interior of the first member and the exterior of the fourth member. The nonsealed association of the third and fourth members provide a hydraulic medium communication between the second chamber and the interior of both the third and fourth members. An arrangement is disposed in the second disc for hydraulic communication between the first and second chambers. At least one passageway is provided extending transversely from the interior of the fourth member to the second chamber. A control sleeve carrying thereon an inert mass slidably engages the fourth member adjacent the closed end of the first member and the one passageway and is responsive to deceleration of the load. This latter arrangement closes the one passageway when the deceleration is less than the given amount and opens the one passageway when the deceleration is greater than the given amount to reduce the damping of the shock absorber.

摘要： A railway car underframe includes at each end thereof an end-ofcar cushioning installation including a hydraulic cushion which is movable between neutral, draft and buff positions during impacts on the coupler. The arrangement includes a cushion pocket having a piston rod anchored therein against longitudinal movement and includes a stop which in the buff position is engaged by a sliding collar slidingly supported on the cushioned cylinder and which is retained against the stop by means of a coil spring held captive on the cylinder. Under conditions of draft impact the cushioned cylinder during longitudinal movement compresses a plurality of spring leaves supported in the pocket and the collar is moved longitudinally away from the stop arrangement.

摘要： A double-acting hydraulic cushioning device for railway cars is formed with a hydraulic fluid filled cylinder having a closed end and an open end through which a piston rod is movable for reciprocating a piston within the cylinder. A flexible accumulator boot is connected to the piston rod and to an intermediate cylinder head for closing the end of the cylinder. A metering pin cooperates with the piston for providing a relatively constant metered flow from the cylinder to the accumulator during the buff stroke on the unit. The piston is provided with a sliding valve and orifice plate which cooperates with the metering pin to meter the flow during the buff stroke and to move to another position during the return stroke thereby permitting an increased flow of fluid from the accumulator boot through the cylinder. The intermediate cylinder head is provided with a cavity which contains a fluid pressure responsive valve slidable to open passages leading from the accumulator boot to the cylinder and in a return and draft stroke of the piston the valve being movable over the passages to restrict the flow therethrough. The valve plate and the piston has a configuration which permits misalignment of the piston relative to the axis of the cylinder without affecting the metering operation. Further, the piston is provided with a piston ring engaging the cylinder wall with the piston ring groove on the piston being designed to permit misalignment without affecting the sealing relation of the piston ring. The slidable valve plate within the recess or cavity of the intermediate cylinder is also of a flexible construction which in the event of misalignment does not impair its functional operation.
