Abstract

830. Marx, E., and Heuer, P. Jan. 12. Variable-speed gearing for use with machinery, vehicles, and the like. The shaft C, Fig. 1, is to be driven at a variable speed, and the hollow shaft A surrounding it is driven at a constant speed by means of a belt on the pulley P. The conical pulley N is formed in one piece with the pulley P, and is geared, by means of a crossed belt T passing over guide-pulleys V, with a similar conical pulley S on a hollow shaft U also on the shaft C. Pinions D, M are formed on, or secured to, the shafts A, U respectively, and gear with pinions E, L on shafts H, K ; pinions F, J are respectively secured to the pinions E, L, and gear, on opposite sides, with a toothed wheel 0 keyed to the shaft C. The shafts H, K are carried in a casing G which is capable of rotation. The speed is varied by shifting the belt T along the pulleys N, S by moving the guide-pulleys in a direction parallel to the shaft C. In a modification, the constant-speed shaft A. Fig. 4, is supported at one end in, and is free to rotate in, the variable-speed shaft C ; the pulleys N, S are carried by parallel shafts, the pulley S being rotated at a constant speed by means of the belt R ; and the pulley N forms a housing for the gearing D, E, F, M, L, J, 0 arranged as shown in Fig. 1. The belt T is moved along the conical pulleys to vary the speed. The planetwheels E, L may be arranged on a common axis of rotation with the driving-wheels J, F to dispense with a second driving-wheel and axis of rotation.
