Abstract

725,684. Securing gear wheels on shafts. HARTMANN, W. Feb. 9, 1953 [Feb. 7, 1952], No. 3553/53. Class 80 (2) [Also in Group XXXI] In a bicycle having an auxiliary power drive of the front wheel (see Group XXXI) a gear wheel 12 is drivingly connected to a shaft 13 by rollers 27, 28 mounted on the wheel 12 engaging flats on the shaft 13 so that the drive is transmitted when the shaft 13 moves axially relatively to the wheel 12. Alternatively the wheel may be provided with three rollers, the shaft being then of triangular cross section.
