in the case l, and engaging with a bevel wheel surrounding the differential, which is enclosed in the case m upon the back axle.

In ordinary driving the power is conveyed from the motor direct through the shaft to the bevel gearing, which is a good point. To obtain the second of the three speeds provided, a

lever worked by the hand is so actuated that the two shafts are separated by forcing the serrated clutch g apart, and at the same time causing the secondary shaft o, which is pivoted eccentrically in its bearings, to be rotated, so as to bring the two gear wheels p and q, which it carries, into contact and gear
