TRUNK AND TIRE CARRIER
INSTEAD of using one special place on
the rear of the automobile for tires,
and another special place for the motor
trunk, accessory manufacturers are combining
the two, and making them utilize

the same space. The round trunk is just
as efficient as the older square kind for

CAR STETHOSCOPE
TF you wish to get right down to business
on your motor when you don't
like its sound and yet can't quite diagnose
the trouble, use a homemade stethoscope.
This can be made of an ordinary telephone
receiver. Attach to it a long iron
rod. The rod can be soldered

phone receiver. The rod should be long
enough so that it can touch the motor at
the other end. The diagnostician can
accomplish his task easily with this
stethoscope, as he can detect the vibrations
through the receiver as they pass
through the motor up along the rod to
the receiving diaphragm.

REMOVES BROKEN SCREWS
AND STUDS
THHAT most annoying of jobs in a
repair shop—removing broken screws
and studs—is reduced
to a pleasant pastime,
unless the claims of a
well-known tool company
for its new device

is simplicity itself. A
small hole is bored
into the offending
screw, and the tool
screwed in. Since its
motion is the reverse
of that followed by the
screw around its
threads, as soon as the
tool takes hold, the
screw begins to turn
out, and a few twists
bring it forth.
The tool has the
obvious advantage of
never placing the

threads, in which the broken screw is
set, in danger.
