The truck body is mounted on heavy steel wheels,or if desired, the entire rig can be set on a flat-car or othermore substantial mounting. The outfit is protected from theweather by a steel canopy top which is provided with canvas. Compressor. curtains. The air compressor has a displacement of 150 of free air per minute, and requires 32 HP. for operationagainst 100 lb. pressure. The air is admitted and dischargedfrom the cylinder by means of the Sullivan improved wafervalves. The compressor is cooled by an open hopper jacket intowhich water can be poured from a bucket or through k, economy is effected when air is not required by aft un-loading device and pilot valve, connected with the air. .re- (125) 418 Engineering and Contracting for April 7, 1920. ceiver which raises the inlet valves from their seats whenthe demand for air temporarily ceases. The engine adopted for driving the compressor is ot anextremely rugged and reliable type. The engine cylindersare cast en bloc with removable head. The engine is pro-vided with three-point suspension and all mechanism is en-closed and adjustable by means of a movable covering. The gasoline supply tank will hold 23 gal.,
