Abstract
356,497. Securing cranks and sprocket wheels on shafts. RADNALL, E. A., Vauxhall Works, Dartmouth Street, Birmingham. Sept. 20, 1930, No. 28124. [Class 80 (ii).] In a pedal crank assembly for bicycles one end of the crank shaft 1 is formed with two arcuate longitudinal projections 16 having flattened sides to engage a complementary aperture in the crank 17 which is retained by swaging over the projections 16, a washer 20 being trapped between. A collar 5 is forced over the other end of the crank shaft, which may have flats 4, the sprocket wheel 10 being secured on the serrated recessed inner end of the collar by swaging over the end. The crank 13 is driven over the reduced outer end and the parts are subsequently brazed. Oil grooves 2 are provided in the crank shaft, and the whole structure may be plated.
