24,929. Allen, A. J. Oct. 2. Variable - speed gearing. - Consists in a catch arrangement for changing speed in a threespeed epicyclic gear for bicycles and motor - cars. A plate Supon a cycle crank-shaft A may drive the chain-wheel H directly through a free-wheel clutch for the low speed. The plate S carries studs forming bearings for compound planet pinions P. The smaller components of these pinions are in mesh with a sun pinion P<3> connected to a toothed disk D<3>. The larger components are in mesh with a ring of teeth R on the wheel H and with a sun pinion P<2> connected to a toothed disk D<2>. A catch K may be moved so as to stop the disk -D<2> for the intermediate speed or so as to stop the disk D' for the fast speed.
