T h e oper:~tion of the gear is very simple. As the steering wheel and cam
are rot:lted, the hemispheres and follower engaging the cam are moved back-
wards and forwards in the groove, thus imparting the required motion to the
d r o p arm : ~ n d drag link. At the snmc time each hemisphere aligns itself in
its seating to the side of the track engaging with it, and the follower, complete
with its four hemispheres, also adjusts itself in the bearing in the rocker shaft.
It will he seen from this that a consider:~ble area is always evenly
presented to the csm track by the hemispheres, and this area and the self-
alignment of the contacting faces is the fundamental difference between the
Marles-Weller and other types of steering gears.
T h e area and the self-alignment explained above are responsible for the
sweet perfornunce and long life of the Marles-Weller gear, the same action
being available throughout the whole of its movement.
