Abstract
538,539. Winches. COOKE, C. May 13, 1940, No. 8561. [Class 78 (v)] A power winch for hauling timber &c. has double-walled side frames between the confines of which are located the drum driving gears and brake. A gear wheel E, locked by dogs to the winding drum C, is disposed between the walls A, A<SP>1</SP> on one side, and a brake pulley is located between the walls B, B<SP>1</SP> on the other side. The flanges D of the drum C occupy openings in the walls A<SP>1</SP>, B<SP>1</SP>, and the cable T passes between vertical rolls S<SP>3</SP>, and, optionally, horizontal rolls to the load. A high-speed pinion H<SP>1</SP> is slidably mounted on a power shaft H driven through a sprocket J by a chain passing over a sprocket on the power unit of a vehicle to which the winch is attached. A low-speed pinion K<SP>1</SP> is slidably mounted on a shaft K geared to the shaft H by sprockets and chain H<SP>2</SP>. Either of the pinions H<SP>1</SP>, K<SP>1</SP> can be slid into engagement with the wheel E, or both out of gear therewith, by a lever L rocked by a handle L<SP>4</SP>, or link connected thereto, to one of three positions. The brake band F<SP>1</SP> can be tightened by a hand-wheel O, which may have a quick-action device, or the latter may be separately arranged. A removable detent may bear on the teeth of wheel E. A pivoted sprag Q can be raised by the cable T, the latter being put over an idle pulley V for this purpose, and the sprag is held up by pivoted catches R taking over studs R<SP>1</SP>. Brackets P may be provided for bolting to the rear axle differential casing of the vehicle. Ball or roller bearings for the drum and power shafts are mounted on the outer walls A, B.
