Abstract: 218,374. Armstrong Siddeley Motors, Ltd., and Bonnaud, H. M. April 3,1923. Declutching for steering; differential gearing. -In tractors or like vehicles of the kind in which a loosely-mounted winding drum is mounted upon a transverse axle so that it can be clutched thereto and driven at the same time as the road wheels, or separately, an arrangement of parts is adopted in which the drum is mounted upon one part of a divided differentially-driven shaft, the outer ends of which are indirectly connected through clutches with the road wheels, while the inner ends are provided with means for locking the differential gear to produce a solid drive. In the illustrated construction the four sliding clutches are arranged on the differential countershaft, the clutch E<2> for locking the differential gear, two separately acting clutches E<3> for driving the road wheels, and the clutch D for driving the winding drum A. The drum A is situated in the transmission system between the changespeed gear and the road wheels, so that any change of speed of the vehicle is transmitted automatically to the drum. The diameter of the drum and the ratio of the gearing is chosen so that the drum will wind up an anchored cable at the same rate as the vehicle moves forward, the cable thus coming into action automatically to take the pull of the vehicle immediately the road wheels slip. The drum may be furnished with change-speed gear for use when hauling with the vehicle stationary, this gearirg not being used when winding up the anchored cable with the vehicle running. The clutch E<2> is operated by a rod E<3> sliding within a hollow shaft and operated from a collar E<4>. By locking the differential gear the remaining clutches can be manipulated to apply the whole engine power to one wheel to facilitate turning, the other wheel remaining unclutched during the process.
