This invention'relates to the construction of
motor ‘vehicles; and, more particularly, to the
trunnion or cross shaft mountings for the clutch
and brake pedals and the arrangement of the
clutch and brake operating means therewith.

When the clutch is disengaged and the brake is

with individual mountings for the pedals, clutch

less, by weight, than that used in the more usual
types. At the same time it is possible to make use
of stampings rather than forgings, with a con
sequent economy. Further, the use of a single
