Abstract: A shock mount assembly for holding a component includes three sets of elastomeric members with each of the sets being disposed at right angles with respect to each other. One set of members is primarily in compression with the other two being primarily in shear resulting in deflections being the same regardless of the directions of applied external forces.

Abstract: A tilt system for a railway car includes mechanical actuating members for tilting the car only when lateral acceleration forces exceed preselected minimum levels. A mechanical stop mechanism is provided to selectively permit the tilting operation to exceed non-tilt stop positions.

Abstract: Methods and apparatus for testing automotive and truck wheels and hubs include placing a wheel connected to a hub and an arm or axle like member into a frame which maintains the wheel relatively fixed. Actuators are provided to apply forces to the wheel through the axle and hub. The forces are applied in different directions with the actuators being programmed to simulate actual road conditions over a long period of time in a relatively short test time without requiring substantial rotation of the wheel.

Abstract: A panel of a trailer is adhesively bonded to a plurality of horizontal and vertical support rail structures which are secured to the main body of the trailer. Each of the structures include a pair of rail elements through which loads are transmitted into the panel by means of adhesively bonded joints between edges of the panel and the rail elements to provide sealing and support for the panel.

Abstract: An emergency release handle is pivotally mounted within an interior wall of a railcar and connected to pull a cable under emergency conditions to actuate a mechanism, such as a mechanism to open a door. The handle is normally maintained inside the wall by a flexible guard plate and retaining screws passing through screw holes which are connected to the wall surface. Manual gripping means is connected to the handle to permit a person to grip it and pull to cause the flexible guard to flex and pass the retaining elements and permit the handle to pivot and pull the cable.

Abstract: A low rate soft primary system for a railway truck includes a pair of longitudinally disposed assemblies on opposite sides of a journal bearing for carrying a wheel-axle unit. Each of said assemblies includes a plurality of laminated rubber strips separated by relatively thin metal strips oriented parallel to the vertical axis of the journal bearing. The layers of the laminated assembly form angles opening towards or away from the journal bearing somewhat in the shape of chevrons. The assemblies provide relatively high spring rates for lateral and longitudinal loads and low spring rates for vertical loads.

Abstract: A transfer machine for holding and moving work pieces from station to station for successive machining operations in which the work pieces are clamped to pallets disposed generally vertically. During loading and machining operations the pallets are clamped in a fixed relationship to guide rails but are moved between stations on anti-friction means in the form of rollers. Loading operations are conducted relative to an accurately located reference axis and a work piece is transferred to the pallet so that the location of the reference axis is accurate at each of the loading and machining stations.

Abstract: Three parameters represent speed, current and voltage are combined to produce an electrical signal representing a desired uniform heat for an operation in which a movable workpiece is involved. A set of electrical signals are developed during the actual operation and combined with the electrical signal representing the standard heat. A resulting error signal and feedback circuit maintain the heat at the workpiece substantially at the desired uniform heat.

Abstract: A coupling assembly is provided to control the movement between two structural bodies when different forces are applied thereto. Initially, a restraint and limited movement is permitted by an elastomeric member for relatively low differential forces. With high differential forces, the restraint is overcome and the structural bodies move with respect to each other on a low friction member.

Abstract: A blind rivet is disposed to be inserted through openings in a pair of structures. The rivet includes a main stem having a pliable sleeve disposed therearound. The rivet includes a head portion on one end and an enlarged portion or bulb on the other. The rivet is held in place as the head portion is drawn outwardly causing the bulb portion to expand the sleeve so as to provide clinching of the two structures. After the expansion of the sleeve, the stem is driven back into the openings in the structure.

Abstract: A primary suspension system for a railway car comprises one or more leaf springs configured to provide vertical and horizontal portions for vertical and longitudinal compliance. A portion of the leaf spring is curved to wrap around a portion on the wheel journal bearing and rest on the top thereof.

Abstract: A pair of adjustment plates are disposed below a mechanical spring which supports a car body. At least one of the adjustment plates include spaced stepped portions to engage a portion of the other plate with the stepped portion engaged determining the height of the car. When the car load is removed from the springs, the relative positions of the plates may be selectively changed to adjust the height of the car body. A shock absorber is connected inside the mechanical spring and removable through the adjustment plates.

Abstract: A freight car includes main side and end frame beams. Wall structures are connected to the beams and extend downwardly therefrom. A floor structure is connected to the wall structures to provide a lower well arrangement for receiving a trailer therein.

Abstract: An articulated truck joins and supports two adjacent railway cars. A linkage including two pairs of links is connected between the bolster of the truck and one of the railway cars. A common link is connected between the two pairs of link. The linkage and common link forces the truck to maintain a radial position with respect to curves in the track.

Abstract: A primary suspension system is disposed between a journal bearing assembly carrying a wheel-axle assembly and a side frame of a railway truck. A rubber ring having cut-away portions or openings therein is bonded to inner and outer split metal rings. The inner ring is retained by the journal assembly and the outer ring is retained by the side frame.

Abstract: A tire pressure control system includes means for restoring and maintaining specified tire pressure by applying intermittent regulated air pressure to the tire through a rotating seal near the wheel when the air pressure is too low. If the air pressure in the tire is at a predetermined safe operating level, the air pressure through the rotating seal is blocked.

Abstract: A primary suspension system is disposed between a wheel journal bearing and a side frame of a railway truck to minimize acceleration forces from being transmitted from a wheel axle unit to a car body. A pair of elastomeric members form a ring clamped around the journal bearing and are bonded to multiple outer plates disposed in different planes. Relatively low spring rates are provided when one set of outer multiple plates are operative with relatively high spring rates being provided when the elastomeric members are compressed and the inner multiple plates become operative.

Abstract: A solar reflector panel includes a glass reflector element held by a thermoset plastic backing. The backing is molded around the reflector element to provide lips to lock the element in place on the backing.

Abstract: A steerable railway truck includes a main frame structure having a bolster and a pair of side frames to be secured to a car body. A pair of "C" shaped sub-frames are interconnected. Extending arm portions of the sub-frames are slidably mounted to the end of the side frames on shear plate assemblies. Hanger elements extend from the main frame to hold the interconnected sections of the sub-frame. A steering link member is connected between the main frame and one of the sub-frames to force the two frames to steer when the car body moves over curved tracks.
