Abstract: A two piece hand brake release handle for a railway car hand brake mechanism having a relatively long lever one end of which is rotably fitted onto a rotatable brake release post extending from the hand brake mechanism, such that manual rotation thereof will not cause rotation of the brake release post, and a relatively short lever arm tightly fitted onto the brake release post such that rotation thereof will cause rotation of the brake release post, with the relatively short lever arm having an arm engaging flange extending transversely to receive and engage the relatively long lever arm such that manual rotation of the long lever arm in a given rotational direction will cause the long lever arm to engage the flange so that continued rotational movement of the long lever arm in the same rotational direction will cause rotational movement of the short lever arm, and accordingly, rotational movement of the brake release post as necessary to effect a brake release.

Abstract: A power transfer device for a motor vehicle having a modular housing assembly which supports a geartrain. A first embodiment of the modular housing assembly includes a case having unitary sidewall with terminal edges defining two opposed openings. The sidewall also defines an interior chamber and the openings are enclosed by a pair of cover plates. Pillow blocks are used to support the drive components of the geartrain within the chamber and are secured to shelves which extend from the sidewall. Loads created during operation are transmitted from the geartrain to the sidewall. The cover plates are secured to the terminal edges of the sidewall using a plurality of U-shaped spring clamps. A second embodiment of the modular housing assembly includes a box-like case having one open side. A cover plate is used to enclose the geartrain and lubrication fluid within the interior volume of the box-like case.

Abstract: A chain tension relieving device which prevents excessive tension being applied to a tension run of a chain. A shoe (5C) engages a tension run (3B) of a chain (3) stretched between a driving sprocket (1) and a driven sprocket (2) from another side of the chain in a bowed portion of the chain (3). When the tension acting on the tension run (3B) is of a prescribed value or less, the shoe surface of the shoe (5C) is held to a given advanced position so as to bow the tension run of the chain (3) by a biasing force of mechanical tensioner (15D). When the tension exceeds the prescribed value, the tension side (3B) of the chain (3) is straightened against the biasing force of the mechanical tensioner and the shoe surface of the shoe (5C) retreats from the given advanced position.

A friction device is connected between the transmission elements. The friction device has a friction element with at least two different friction areas. The friction element is arranged in a circumferential opening having circumferential ends in one of the transmission elements. As long as the friction element is movable within the circumferential opening relative to the ends of the circumferential opening, only a first friction area of the friction element is active. When the friction element contacts one of the circumferential ends of the circumferential opening, only a second friction area of the friction element is active.

Abstract: A vehicle accelerator pedal apparatus has a fixed base (i.e., a base fixed with respect to the vehicle upon which the apparatus is used) and an accelerator pedal pivot-mounted with respect to the base. The improvement comprises a frame pivot-mounted with respect to the base and defining an included angle therebetween. A sensor is mounted on the frame and an articulated linkage extends between the pedal and the sensor.
