Abstract: An improved method is used to control the pressure in the brake pipe of a train. The train is equipped with an automatic brake handle, an equalizing reservoir, a brake pipe control device and a computer for controlling the control device according to position of the handle. The method involves the steps of: moving the handle to a point along its range of motion; and storing in the computer as a setpoint the value desired for the pressure in the brake pipe. At whichever point the handle occupies along its range of motion, there is a particular pressure setpoint corresponding thereto. The method next includes the steps of: directing the computer to command the control device to modify the actual pressure in the equalizing reservoir to the setpoint thereby also causing the actual brake pipe pressure to approach the setpoint.

Abstract: A wheel rim clamping device is disclosed which has a plurality of pressure applying surfaces for clamping a concentric wheel rim to an axle hub assembly so as not to deform the rim and to improve the load transfer between the rim and hub. The clamping device, in one embodiment, includes an arcuately shaped main body portion and a plurality of alternatively offset, bent over, pressure applying surfaces along the outer longitudinal edge portion of the main body. The pressure applying surfaces grip both sides of an inwardly directed rim locator ring which extends around the interior periphery of the rim. Drive lug recesses are formed between the pressure applying surfaces to accept rim drive lugs which are spaced along the rim locator. The pressure applying surfaces and rim drive lugs lock the rim in place. The inner longitudinal edge portion of the main body includes downwardly extending and radially spaced apart depending leg portions which are mounted to the central axle hub assembly.

Abstract: A demountable wheel rim assembly for a road vehicle and comprising a rim and an adapter band extending outwardly well beyond the rim so that two assemblies can be placed on a hub for a dual-type wheel with the bands abutting to space the rims without a separate spacer band. The band may have notches or openings in its free end portion to receive clamps for use when it is mounted singly on a hub.

Abstract: Tire carrying rims seated and locked on vehicle wheels by fastening assemblies. A wheel has spoke members with dimensioned felloe surfaces for mating engagement with a radially inclined surface on a rim base edge portion and for coaction with a series of clamp lugs having radially inwardly directed leg portions and being integrally secured to a radially directed axially outer rim base surface. Rims may be dual mounted in mating, seating or full surface engagement with coacting felloe surfaces of the rim and wheel by full tightening of the fastening assemblies.

Abstract: A wheel rim such as used on a mobile home and trailer is provided with a non-slip interlocking device and has on its inner periphery a substantially radial surface which is mountable upon a wheel hub. A plurality of spaced recesses are formed in the radial surface for engagement for correspondingly spaced and shaped raised portions on a wheel hub so as to prevent slipping between the wheel rim and hub after the rim has been mounted upon the hub.

Abstract: Tire carrying rims seated and locked on vehicle wheels by fastening assemblies or means. A wheel has spoke members with dimensioned felloe surfaces for mating engagement with coacting surfaces on radially inwardly projecting mounting flanges integrally attached to and mounted beneath a base portion of the rims between the bead flanges. Rims may be single or dual mounted in mating, seating or full surface engagement with coacting felloe surfaces of the rim and wheel by full tightening of the fastening assemblies or fastening means.
