Abstract
225,134. Barford & Perkins, Ltd., and Hood, G. W. L. May 23, 1924. Variable-speed and reversing gearing.-In two-speed gearing or reversing gearing in which alternative trains are brought into action by friction clutches, a single spring functions to hold either clutch firmly in engagement. Friction clutches 2, 3, Fig. 1, entraining gears 9, 10, alternatively are operated by moving a sleeve 21 along shaft 1. The sleeve 21 is operated by a double lever 22, Fig. 3, pivoted at 23 and operatively connected to a nut 24 upon a screw 25, Fig. 2, of steep pitch. A crank 27 is acted upon by a spring 31, Fig. 4, arranged about a link 28 so that the crank after passing its dead centre is held hard over as far as it will go. In changing speed, the crank is turned as far as its dead centre by manual means acting through a sprocket 35, Fig. 2. The invention is adapted to combine with a complete change-speed gear to yield a second or a reversed range of speeds.
