PATENT 30828 of 1989
This patent returns to the design of the Greenfield clutch assembly,
and in particular, a refinement to the �Clutch Fork Supporting Bracket�.

The new design was intended to overcome a potential issue in the previous design:
A difficulty associated with such drives is that the power
transmission from the clutches to the rear wheels is
dependent upon the engagement force between the
clutch plate and the associated pulley wheel. This
engagement force which is effected through a clutch actuator
may be insufficient in certain instances to enable the full
available power to be transmitted.

However, a more careful reading of this patent seems to indicate this
new design was more an expression of the need for a simpler design for
production purposes (automatic welding).
