Abstract

343,832. Variable speed gearing. BRASE, W., 34, Am Treptower Park, Berlin. May 5, 1930, No. 13778. Convention date, June 27, 1929. [Class 80 (ii).] Comprises at least one two-speed unit having a driving - pinion 7 adapted to engage either of two toothed rings 6, 4 inside a drum 1 which is supported in fixed bearings 2. The ring 6 is of the same size as pinion 7 so as to produce a clutch engagement. The ring 4 is larger, and when driven produces a reduced drive. The pinion 7 in passing between rings 4, 6 passes along a spiral toothed track 5. In Fig. 3, two units A, B are shown in series connected by a universally jointed shaft 21a. Each pinion 7 is supported in a bearing 8 which swings and slides on a guide-rod, not shown, under the control of a pin which, in speed changing, is advanced into engagement with a helix 15 on the outside of the corresponding drum 1. An arrangement is described suitable for driving a vehicle in which the driving-shaft 21 of the first unit A is driven through a bevel clutch reversing-gear, and in which the drum 1 of the second unit B drives a tail shaft through a clutch.
