Abstract: A method for adhesively joining two members includes the steps of mixing non-compressible beads with an adhesive, applying the resulting mixture to one of the members and hemming one member over the other in overlapping relationship. Apparatus for performing this method includes a container for containing a mixture of an adhesive and a plurality of non-compressible beads, an applicator for applying the mixture to one of the members, and hemming apparatus for hemming one member over the other in overlapping relationship. A metering device for dispensing adhesive fluid is constructed with a dispensing rod having a cooling apparatus for facilitating operation of the metering device. The present invention finds particular utility in bonding together the inner and outer panels of an automotive door assembly.

Abstract: A test apparatus for testing hem flanges that join automotive body panels is provided. This testing apparatus operates by engaging a hook member with a first body panel such that the first body panel is maintained in a held relationship with respect to the hook member. A ram member then extends from the testing apparatus and engages with and loads a second automotive body panel member. As a result, a tensile load is applied to the hem flange, permitting the hem flange to be analyzed for defective construction.

Abstract: A robot hand adaptable to a robot arm for rigidly connecting a work tool to a robot arm while the work tool is positioned, but appropriately aligning and substantially isolating the work tool from the robot arm during the work tool's manufacturing operation.

Abstract: A primary suspension system includes a pair of spaced vertical springs connected between a journal bearing retainer and a side frame of a railway truck. Pairs of angularly disposed elastomeric springs are also connected between a lower support housing and opposite angular ends of the journal bearing retainer to provide lateral and longitudinal stiffness.

Abstract: Damping elements physically contact some of the coils on one or more mechanical coil springs disposed between a railway car body and a truck. The coils contacted may be at the ends of the springs or at areas between the ends. When double springs are involved, with one being spaced within the other, the damping elements are disposed in the space between the springs at the ends thereof.

Abstract: In a railway truck, a primary suspension system comprising a pair of elastomeric half-ring members having high wear flexible woven material bonded thereto and on opposite sides thereof; the woven material having high flexibility and wear resistance perpendicular to the plane of the material and rigid within the plane of the material.

Abstract: A mounting member is disposed on one end of a mechanical spring to prevent vibrations from a truck being transmitted into a car body for transmitted to the spring and car body if mounted below the spring. The mounting includes a pair of elastomeric rings, with one of the rings providing vertical compliance and the other providing lateral compliance between the truck and car body.

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: Emergency springs are disposed within air springs which are used for normally supporting a railway car body. When the air springs fail, the car body is supported by the emergency springs. Each of the emergency springs includes a conventional spring in combination with a pair of angularly disposed springs which changes operating chracteristics when the load is increased.

Abstract: A water cooling loop is connected to cool an engine of a railway car or the like and includes a heat exchanger. A system for heating a compartment includes a pump for pumping water to heating elements. The water from the pump is selectively pumped through a first path which includes the heat exchanger or through a second path which by-passes the heat exchanger dependent upon the temperature condition inside the car.

Abstract: A bolster for carrying a car body rests transversely on a pair of side frames of a truck. A side bearer and wear plate assembly are disposed between the ends of the bolster and the side frames to permit the bolster to be rotated relatively about small angles with respect to the side frames. The side bearers each comprise a body having relatively low friction surfaces in engagement with the wear plates. Each of the low friction surfaces may include two or more parallel arcuate tracks or segments which may have radii corresponding to the directions of angular rotation movements of the bolster. The total surface area of the low friction surfaces is designed for optimum operation for predetermined load conditions.

Abstract: A railway car includes prime movers mounted to a car body directly connected to pairs of gear boxes to drive pairs of axles mounted on a pair of trucks, with direct connections between the gear boxes and the connections being such so as to permit independent removal of the trucks from the prime movers and to facilitate the installation of interchangeable variable speed drives.

Abstract: This application discloses a railway vehicle truck of a general configuration having independently movable side frames, wherein the side frames are provided with resilient connections with the wheel-axle units which allow universal turning movement but substantially inhibit relative axial movement; wherein the side frames are connected at longitudinally spaced points by transverse cross-frame or transom bar members which are rigidly connected to the side frames at one end and connected to opposite side frames by true turning shaft-bearing joints which also, when needed, provide limited axial movement, the shaft-bearing joints having axes disposed on a line passing through the vertical axis of turning of the truck whereby the transom bars positively maintain the truck in tram; wherein a center frame is mounted at longitudinally spaced laterally central points on the transom bars by resilient joints which are spaced approximately the same distance from the transverse vertical central plane of the truck as the s
