29 and 35 terminate in close proximity to the
terminate by inner closely spaced apart ends and
diverge therefrom throughout the arcuate lengths

By vsuitable rocking of the fork 9|, the sleeve 85

may be incorporated vwithin the transmission
housing 12 as may be desired, but such gearing
does not specifically enter into my invention,
-and itA is no-t necessaryy to its operation and
therefore is not shown. _ However, I do provide
what I ~ term` a stabilizer which is in the nature .
of a clutch although no direct drive is taken
therethrough. The purpose of this stabilizer is
not only toi dampen out'vibrations, butalso to
control the `relative speeds between the shafts
15,13,Y and 45 to permit shifting from a neutral
or no-'drive arrangement to a direct driving
connection or to permit shifting of the various
members to the reverse drive connection.
In the present showing, I mount a clutch plate
91 on the .hub -53 to have a contact face in a
plane normal to the V.axis of the shaft 13. Lon

between the web 84 in the housing ‘12 and the

_ingly dogs |92 that extend rearwardly -fromva
