  • Patent number: 4276952
    Abstract: PCT No. PCT/US79/00158 Sec. 371 Date Mar. 16, 1979 Sec. 102(e) Date Mar. 16, 1979 PCT Filed Mar. 16, 1979 PCT Pub. No. WO80/01894 PCT Pub. Date Sept. 18, 1980A vehicle component (10) is removably mounted on a stationary support (11) thereof. A pair of rollers (17,17a) rotatably mounted on the component (10) each engages a rail (18,18a) secured on the support (11) to thus precisely guide movements of the component (10) upon installation or removal thereof. The apparatus of this invention provide for the expeditious and precise handling of the component (10), compensate for avoidance of interference with structural parts of the vehicle during such handling, and are adapted for use with components, such as modular transmission packages having varied designs.

  • Patent number: 4262550
    Abstract: A governor and decelerator control linkage has two shafts (16 and 17) journalled in a housing (10) and a one-way coupling (18) permits rotation of the second shaft (17) either independently of the first shaft (16) or as a result of rotation of the first shaft (16). A lever (19) fixed to the second shaft (17) may be moved between first and second limit positions by moving a lever (24) on the first shaft (16) or may be moved between the first limit position and an intermediate position by moving a third lever (28-29) which is mounted on a third shaft (27).

  • Patent number: 4053409
    Abstract: A filter assembly comprises a cover member detachably mounted on a stationary support and a support member attached to the cover member in axially spaced relationship therefrom. A tubular screen, having a filter disposed therein, is disposed axially between the cover and support member and defines an annular passage between it and the filter. In normal operation, fluid is communicated from an inlet, through the screen and filter and to an outlet. When the pressure of the fluid in the passages exceeds a predetermined level, the fluid is communicated from the inlet and through the screen and passage to open a bypass valve mounted in the cover to communicate the fluid directly to the outlet. A plurality of magnets are preferably secured on an underside of the support member and adjacent to the inlet to uniformly disperse the fluid thereby and to pick up metallic contaminants.
