sCHACHT TRUCK
HAS TEN SPEED
TRANSMISSION
Made by the 6. A. Schacht Truck
Company, of Cincinnati, with Branch
at No. 422 East Fifty-Fourth Street.

AS its name implies, the Schacht ten
speed transmission provides ten different
road speeds-twice the number OF speeds
provided by the conventional four speed
transmission. ."
Although the Schacht ten speed trans
mission may properly be termed two
transmissions in one." since 1t actually
doubles the range of the average four
sreed transmission, this is accomplished
without sacrificing simplicity in construc-
ton and without complicating Its opera
ton. Any novice can learn to manipulate
the gear shifts as easily as any other
transmission, while provision has been
made to eliminate the possibility OF strip
ping gears by the inexperienced or careless
driver. 3
The Schacht ten speed transmission is
SO compactly arranged that only three
more gears are required than in the regu-
lar four speed, while the transmission case
is only slightly larger.
The primary purpose or the Schacht
fan speed transmission is to create wide
range of power reductions. so essential II
a heavy capacity truck is to operate at
full efficiency at all times. In otner
words. the two extremes-high vehicle
sneed and extraordinary pulling power
enabling a heavy duty truck to adapt itself

operated-are made possible py he
Scbacht ten speed Transmission.
Twenty to twenty-five miles an hour on
high gear is easily attained over a gooo
level road with a five ton truck, %nicn a.
the same time has a low gear reduction
suff,cient TO negotiate any kind of road
