  • Patent number: 4266438
    Abstract: A shift mechanism for the gears of a transmission is disclosed having a pivotally mounted bushing assembly. The bushing assembly defines an aperture. Positioned in adjacent, spaced apart relationship to the bushing assembly is means for selectively engaging one of a plurality of gears in a transmission. A shift lever is rotatably positioned in the aperture in the bushing assembly. One end of the shift lever is adapted for drivingly engaging the means for selectively engaging one of a plurality of gears in a transmission, whereby rotating the shift lever selects the gear in the transmission and pivoting the shift lever engages the selected gear in the transmission.

  • Patent number: 4259877
    Abstract: A shift mechanism for the gears of a transmission is disclosed having a pivotally mounted member. The pivotally mounted member defines an aperture. A shift lever is rotatably positioned in the aperture of the member. A shaft is positioned in adjacent, spaced apart relationship to the member. A shift finger is pivotally and slideably positioned on the shaft. A first bracket is connected to the shift lever. The first bracket is adapted for drivingly engaging a portion of the shift finger and sliding the shift finger on the shaft, whereby the shift finger is moved to select a different gear. A second bracket is connected to the member. The second bracket is adapted for drivingly engaging a portion of the shift finger on the shaft, whereby the shift finger engages the selected gear.

  • Patent number: 4104929
    Abstract: A shift mechanism comprises a shift lever adapted to effect the engagement of transmission gears. The lever has a main shaft which is rotatable about its axis and pivotable in a plane containing its axis. Shifting is therefore effected by a combination of rotary and straight line movements. A rigid member extends from a bottom portion of the lever main shaft to a location radially spaced from the main shaft axis to effect a selection of gates of the transmission when the shift lever is rotated.

  • Patent number: 3955442
    Abstract: A plural power path torque transfer mechanism for incorporation in a four-wheel drive vehicle between a source of input torque and a pair of front and rear drive axle assemblies. The torque transfer mechanism includes a housing having an input shaft connected to the source of input torque and a pair of spaced output shafts each adapted to be connected to one of the axle assemblies. Plural power paths are established between the input and output shafts by selectively engaging either a gear drive unit or a chain drive unit.
