Abstract
1,058,999. Winch drive gearing. C.D.P. SMALLPIECE. Oct. 19, 1965 [Oct. 30, 1964], No. 44341/64. Heading B8B. [Also in Division F2] A two-speed winch in which the drum 16 is journalled on a stationary shaft 11 comprises a manually rotatable reversible driving pinion 21 meshing with a gear 20 integral with a gear 23, internal gear 24 and external gear 25 journalled coaxially about the shaft 11 and incorporating ratchet teeth 26 and 27 respectively, and pawls 28, 29 pivoted to the drum body 16 to take the drive from either set of ratchet teeth depending on the direction of rotation of the pinion 21. While one pawl transmits the drive the other free wheels. The drum 16 is journalled on the shaft 11 between end plates, one of which supports the pinion 21 and integral gears 20, 23. In a further embodiment, Fig. 3 (not shown), the internal gear is formed on the inside of the drum and engages a gear freely mounted on the drive pinion shaft and coupled thereto by a freewheel arrangement. In the embodiment of Fig. 4 (not shown), the drive pinion (21) is mounted eccentrically on its shaft and the meshing gear (20) is contained to receive the eccentric motion.
