The Norwalk
Air Compressor

OF STANDARD PATTERN

is built with Tandem Compound Air Cylinders. Corliss Air Valves on the intake cylinders insure small clearance spaces. The intercooler between the cylinders saves power by removing the heat of compression before the work is done, not after, and the compressing is all done by a straight pull and push on a continuous piston rod. The Compressor is self-contained; the repair bills are reduced to a minimum, and the machine is economical and efficient. Special machines for high pressures and for liquefying gases.
