Abstract

415,085. Toothed gearing. BARTLETT, B. G. W., 1, Cartmell Terrace, Darling- ton. Nov. 17, 1932, No. 32564. [Class 80 (i).] A power-transmission mechanism for cycles, &c. comprises an annular gear member 1 which transmits the drive from a chain 4 or toothed gear to a driven member 7 and is supported by a roller 11 at a point between the ends of the diameter connecting the points of application of the driving and driven forces. A second roller 11<a>, Fig. 6, may be provided on the opposite side of the said diameter for supporting the annular member during reverse drive. The driving and driven members may engage the exterior and interior respectively of the annular gear, or vice versa ; or both may engage the interior or exterior of the gear. The rollers 11 engage the interior of the annular gear when the driven member is external thereto and vice versa. The internal gear on the annular member may comprise a chain pressed into a groove therein and engaging sprocket teeth in the wheel 7. The teeth of all members may be shrouded to the pitch circle diameter and the roller 11 may be toothed to engage teeth 9 on the shroud of the gear 1. The annular gear may be a disc having flat or bevelled flanges for engagement with the other gears supported on stub axles on either side of the disc.
