To eliminate drive roller slippage and to

assure smooth

starts,

a

system of two disc

compression springs

is

employed. When the

speed selector lever

is

placed in gear,

the

primary disc compression spring creates

initial

drive roller pressure against the drive

disc.

Momentarily,

the

drive roller

is

al-

lowed to slip, eliminating quick "jumpy"

starts.

The secondary disc compression

spring then goes into effect supplying

ad-

ditional

disc

pressure to propel

the

unit.

(See Figure

2-21.)
