ELECTRIC GARAGE PUMP
THIS electric pumping plant, set on
wheels, is ready to be rolled to any
place where compressed air is desired,
and put into operation simply by connecting
to the next lamp socket and turning
the starting switch. It consists of an
air compressor, set of gears, motor, tank,
manometer, connecting wire to lamp
socket and a steel-covered
hose to connect
to tire. All that is
necessary to do is
watch the gage.

CONVERTIBLE TRACTOR
X" invention by which an ordinary
automobile can be converted into a
farm tractor with little work and little
expense, has been demonstrated in the
Pacific Northwest. The transformation
is effected by the removal of the body
and the mud guards from the machine,
and the attachment of small pinion gears
to the axles in place of the rear wheels.
This gear works in turn on large internal
gears on heavy steel tractor wheels. The
front tires are removed and by means of
a clamp, six-inch steel rims are substituted.
The tractor is capable of doing
the work of four or five horses, and will
pull disc harrow, plow, or manure
spreader. On test the tractor pulled, on
dirt road, three wagons loaded with wet
slab wood, a load of approximately ten
tons.
The power of the car is multiplied ten
times by gear reduction, and when working
in the fields at three or four miles an
hour, the engine speed is no more than
would be required for eighteen to twenty
miles an hour on the road. All work is
done on high gear so that the strain of
pulling and carrying is taken by the
heavy tractor wheels, the motor and
frame being relieved of all of the extra
strain.
The tractor, with little work, may be
made into a pleasure car again.
This Tractor May Be Put Together
and Taken Apart by
Any Small Car Owner
