DESCRIPTION

The Webster-Chicago Model 356-! basic mechan
ism is a three speed, single past, spring cushioned
spindle. automatic Irecord changer. Simple in de-
sign a'nd operation it provides automatic playing
of up to a 1" stack of 7", 10" or 12" records at
speeds of 33%. 45 or 78 rpm.

Model 356 returns the pickup arm to the rest posi-
tion after playing the last 10" or 12" record. al-
though the motor continues to revolve until the
Speed Selector Lever is moved to the nearest
"OFF" position. Two "OFF" positions are avail-
able for ease at operation. The idler wheel is also
pulled away from the motor shaft when the Speed
Control Lever is in an OFF" position, eliminating
the possibility of a flat spot developing on the
rubber wheel.

The last 7" record of a stack continues to play
until the Speed Selector Lever is moved to one of
the "OFF positions and the Pickup Arm moved
from the record to the Rest Position.

Automatic playing of 7" records is made possible
by a simple, ingenious 7" record shell which is
easily placed on the Record Selector Post and by
a movable 7" Pickup Arm Rest which can be
swung into or out at position.

Model 356 also ieatures the exclusive Webster-
Chicago Velocity-Trip Mechanisml The pickup
arm is not actuated by "lead-in" springs and
there is a minimum of lateral pressure. The arm
travels treely in either direction. This lack of lat-
eral pressure or inertia adds immeasurably to the
life of records and is considered to be as impor-
tant as extra-light vertical pressure. The tree-
tloating arm permits home recordings" or inside
out" records up to 12" size to be played manually
