Abstract

258,113. Pearn, H. W. Oct. 30, 1925. Variable-speed gearing comprises an epicyclic train with a non-variable sun-and-planet chain pair f, and a variable sun-and-planet chain pair h, e. The carrier a of the planets drives, and the shaft g of the sprocket f is driven. The variable chain pair h, e may be of any suitable type, such as the type described in Specification 228,838. The wedging action of the chain on the left-hand movable flanges of the expanding chain pulleys e, h shown is balanced upon an intermediately pivoted lever m and control is effected to vary the speed by a lever j. A clutch q, r is provided for connecting a sleeve i carrying the sun gear h to the shaft g for solid high-speed driving. A brake o, p arrests this sleeve while the pair e, h is being varied for reduced forward speeds and reversed driving. This clutch and brake are brought in alternatively by a control lever n.
