Реферат: 20,893. Vaniman, M. Dec. 21, 1905, [date applied for under Patents Act, 1901]. No Patent granted (Sealing fee not paid). Variable - speed gearing. -Relates to variablespeed gearing for motor-vehicles in which worms of different pitches are employed. These worms d, e, f are of different diameters, but their threads are of the same inclination so as to be capable of meshing with the same worm-wheel j. They are mounted so as to slide together on a squared portion b of a shaft a which is universally jointed to the motor shaft at c. A frame g embracing the worms is provided with steps k, l, m on its underside which are supported in turn by a fixed roller o as the worms d, e, f are held in mesh with the driven wheel j. The frame g may be traversed by rack-and-worm and bevel gearing.
