|Quadrant Shaft-Driven Bicycle|
|Manufacturer||Quadrant Cycle Company|
Attempts have been made from time to time to replace the chain drive of the safety bicycle by other forms of transmission; this one is by shaft and bevel gear.
This particular gear known as the ‘cross roller gear' patented in 1897 by Messrs W. & J. Lloyd and W. Priest, friction and wear is reduced by not having teeth pins carrying rollers of conoidal form of bicycle.
The gear was adopted for a time by the Quadrant Cycle Co.
How it works
The wheels have tangent spokes and 1.5 in pneumatic wired-on tyres; the pedals are of rubber.
A hand brake is fitted to the back wheel; the head lamp is an electric bulb supplied with current from a battery. Both wheels are 28 in. diam., the back one geared to 69.3 in.
The crank radius is 7 in. The wheel base of the machine is 43.5 in. and its weight is 41 lb.
