Abstract: A bolsterless bogie for rail vehicles has at least one link which is directly connected to the bogie frame and the rail vehicle center pivot by means of wear-free rubber joints and connecting pins. Rubber buffers limit the transverse motion between center pivot and bogie frame; vertical forces are transmitted by air-spring bellows arranged in the vehicle center plane between the underframe and the bogie side sill, and stops effective in the travel direction are provided between center pivot and bogie frame.

Abstract: The suspension includes a moveable load arm assembly adapted to support a railcar axle, at least one elliptical cross-section rod spring carried by the load arm assembly in load bearing relation with a railcar body, a frictional damping surface connected to the body adjacent the load arm assembly, a frictional damping element, and a tapered operator carried by the load arm assembly in underlying relation with each rod spring such that one component of a load bearing force transmitted from the load arm assembly is applied to the rod spring as a transverse load bearing compressive force only, while a perpendicular component thereof is applied to and urges the damping element toward the friction surface. The suspension is suited for usage in railcar and rubber tired vehicle suspensions.

A gasoline engine is pivotally mounted on the vehicle and is connected to drive the pump.

Abstract: A rail car includes substantially flat plate extensions interposed between upper and lower sections of the shell of the car to increase the internal volume of the car. The extensions are supported by lateral supports which extend laterally in the interior of the car and by longitudinal support beams also in the car interior which extend longitudinally of the extensions, are intersected by the lateral supports, and substantially prevent internal pressure in the car from being applied to the extensions.

Abstract: A hopper car structure having a hopper body with a discharge opening at the bottom. A pivotally hung door having an arcuate base plate normally closes said opening and an arm is pivotally mounted on the door. A roller is carried by the arm on its free end and is intended to engage a ramp. The arm, in the closed condition of the door, has an abutment surface thereof spaced downwardly from an abutment surface of the door. When said roller engages an upwardly inclined ramp, the arm pivots upwardly with respect to the door until the abutment surface of the arm engages the abutment surface of the door. The door and arm then swing together about the pivotal mountings of the door to the open position of the door. The arm is locked against movement while the door is in its closed position and the abutment surface of the arm is spaced below the abutment surface of the door.

Abstract: A fixed sill includes a pair of lower, outwardly extending fixed sill flanges. A generally vertical longitudinally extending support plate is integrally connected to each fixed sill flange on each side of the fixed sill. A sliding sill support is rigidly connected to each support plate. The sliding sill support includes a horizontal inwardly extending portion that also extends longitudinally inboard. The sliding sill support is located slightly below the fixed sill flange. A pair of low friction wear plates are adopted to be slipped in place upon each sliding sill support. The low friction wear plates include horizontal body portions on each side of the fixed sill upon which the sliding sill rides in moving back and forth. Each wear plate includes "U" shaped end portions which wrap around in the inner and outer ends of the sliding sill support.

Abstract: A railway hopper car is disclosed which includes a car body defined by opposite arcuate side sheets having a side sill extending longitudinally along the lower margin of each side sheet and at least a first end slope sheet partially defining an end hopper compartment. An end support structure for the end hopper compartment is secured to the car body and includes a shear plate extending transversely between the side sills, a stub center sill disposed subjacent the shear plate, a bolster beam extending laterally on either side of the stub center sill and interconnecting the stub center sill with the side sill, a vertical bolster web interconnecting the stub center sill and the shear plate, an additional vertical bolster web assembly interconnecting the stub center sill, the shear plate, and the bolster beam, and a plurality of vertical gusset plates interconnecting the slope sheet and shear plate.

Abstract: The device is a cargo restraint mechanism for restraining cargo pallets. The mechanism includes two links rotatably attached to a frame member, and a latch member pivotably attached to the links. One link is provided with a lever and the latch includes a cargo restraint lip. The mechanism is erected by pressing the lever thereby raising the restraint lip above the plane of the top surface of the frame and into a cargo pallet engaging position. A downward force delivered to the top surface of the restraint lip retracts the restraint mechanism beneath the plane of the top surface of the frame. A helper leaf spring follows a cam surface on the other link causing a snap-type action in the mechanism. The frame may include an additional mechanism such as a separately actuatable and retractable seat pallet guide.

Abstract: A device for adjusting the butt-ends of two rails to be connected has a fixed frame for enclosing one of the two rails and two integral bars, parallel to the rails, and extending from the fixed frame toward the other rail. Two movable frames are slidable over a limited portion of the parallel bars in the vicinity of the other rail and can be selectively secured to the other rail so that only one of these two frames is slidably movable. Jacks are provided to effect relative movement between the two movable frames. Actuation of the jacks effects movement of the two movable frames relative to each other and, depending upon which of these frames is secured to the parallel bars, the gap between the two butt-ends will be either increased or decreased.

Abstract: A handbrake arrangement for railroad freight cars is disclosed that will connect a mechanical handbrake operating mechanism to the brake equipment (brake beams and brake shoes) on 2, 3, or more trucks on the same freight car. It is especially useful on articulated freight cars consisting of multiple units in order to satisfy handbrake power requirements required by industry and Federal regulations, but a similar arrangement may be used on special purpose cars having a multiplicity of trucks. On an articulated car, consisting of a number of units, there is a multiplicity of trucks and because of the size and weight characteristics of the car, it is desirable to connect the handbrake mechanism to a number of the trucks in order to provide adequate handbrake power.

Abstract: In a system for holding support elements on a body, which elements can be lded or swung out from the held position, such as support elements used with solar generators on space vehicles, a pin is arranged to carry the support elements and a locking bolt retains the pin in the held position. The locking bolt is biased toward a position where it releases the pin. The pin is tensioned so that it contributes to the biasing action on the locking bolt. A blocking element holds the locking element in position for securing the pin in the held position. When the blocking element is displaced, the locking bolt is released and, due to the biasing action, moves out of the position where it secures the pin in the held position. A number of pin-locking bolt-blocking element combinations can be secured in the held position by a common cable acting on the blocking elements. When the cable is cut, each of the combinations is released at the same time.
