Abstract

12,970. Martin, G. T. June 25. Driving-mechanism; clutches.-Relates to variable-speed gearing for bicycles &c. The pedal &c. shaft 14 is supported by ball bearings 17 in the screw covers 11, 12 of the casing, and carries a toothed bevel-wheel 26 and a clutch member 50. The wheel 26 gears with a wheel 38 of a multiplying-train screwed to a hub 36, also carrying a toothed bevel-wheel 39 and supported by ball bearings 34 carried by a sleeve 31 on a spindle 30 carried by extensions 28 and 29 of the casing, an enclosing casing 43 being provided. A sleeve 20, supported by ball bearings 24 in enlargements 6 of the casing, carries the driving sprocket or toothed bevel-wheel 21 and has longitudinal projections 45, engaging grooves in the hub of a toothed bevelwheel 42, and grooves through which pass screws 47 connecting the wheel 42 to the movable clutch member 48. The clutch members are brought into engagement and the toothed wheels 42, 39 out of engagement, or vice versÔ, by means of a rod operating a lever on a spindle 53 carrying arms 52 having rollers engaging a groove 57 in the toothed wheel 42.
