Abstract

12,010. Luther, O. May 14. Clutches; chain gearing.-In a two-speed gear for cycles and the like two sets of chains and chainwheels are arranged, one on each side of the driving-wheel, the chain-wheels 1 and 2 on the hub 5 of the driving-wheel being equal and those upon the crank axle unequal. Both the chain-wheels upon the hub can turn freely thereon, but either may be connected to the hub by sliding bolts 10 passing through corresponding holes in the sides of the hub and the chain-wheel. The bolts are carried upon arms 12 mounted upon a sleeve 13 surrounding the the spindle 3. A rod 16 enclosed in the spindle 3 is connected to the sleeve 13 by a pin 15 passing through a slot in the spindle 3. A spring 17 presses the bolts in one direction so as to engage the chainwheel 2, and a bell crank 18 actuated by a cord or rod 28 can push them over in the other direction so as to engage the chain-wheel 1. In a modified arrangement, the spindle 3 is dispensed with, the hubs are continued outwards and form short axles running in bearings in the frame 4, and the bolts 10 are carried upon a cross-bar which is actuated directly by a cord passing through an axial hole in the hub and attached by a swivel joint to the cross-bar.
