' blast is approximately tir-teen pounds gage.

The object of' the invention is to remove moisture 'from the air Without necessitating a high compression thereof thus reducing the tendens;7 ol' having leaky joints or bursting pipes in theY apparatus.`

it clear conception of the invention can he obtained by referring to the accompanying drawing which represents the invention applied to an oir drying system.

The prime inover tl of the compressors l., 5, may he a turbine or any suitalole engine,

hy ineens of the linkage 6l to a compressor l. 'lhelinkage 6l is either ashat, as when turbines are used, or a piston rod and connecting rod or rods when reciprocating machinery is used. This compressor L-having its suction through pipe l0, compresses atmospheric air up to sa7 'ten to fifteen pounds gage pressure, discharging the coniressed air through the pipe l2 which leads to the surface cooler 2. ln this cooler 2 the heat dus to compression in the compressor l is carried oil' hy means of any suitable medium, such as water." The coolingwater entersthe cooler 2 through the pipe 2l and passes through the cooling tubes or pipes 20 and is discharged through the pipe 22. During its passage through the tulves 2t), the cooling' medium absorbs the heat ol2 oo nlpression from the compressedair which surrounds the tubes 20, thus leaving the discharged compressed air et approximately the saine temperature as that of the inlet cooling medium. The compressed air from the cooler passes through the pipe 23 into the expanding' engine 3 which is direct connected to the linkage 6l so that during the operation ot expanding the compressed,

air. to atmospheric pressure the expanding engine 3 will assist the prnie mover 6 in' performing the work of driving the com#v pressor l hereinabove mentioned and the compressor 5 hereinafter mentioned. ,ses 60 the air expands to atmospheric pressure in the engine 3, it deposits most of its moisture in the form of Water, frost or snorv in the snow pockets Il, having the door 8 for re'- Inoval of snow. vThis deposition of the as moisture is facilitated by the abstraction of heat in the cooler before expansion'in the engine 3.. The expansion of air in the engine 3 and the translation of heat thereoftt'? into work necessarily causes a: decrease in 70 temperature which :will he' sutcient to liquefy or freeze the contained moisture. After the deposit of the moisture in th@ forniV of water or snow in the snow pocket el, the air at atmospheric pressure @am 15 through .the ipe t5 'into a second compressor 5, 'also direct connected to linkage *6% in which it is compressed to the required 'for use.

lin hlast furnace application, the air ailier 8G leavin the compressor 5 through the pipe 15,is cated up to the required temperature, Vlhen applied to blast furnace use, the essential point is not so much the-removal of moisture as the removal of moisture to 36 'leave the air with as nearly as possible constant percentage "lele--moisture.` lf it were economically possible, entire removal et moisture would'loe the most desirehle con-U dition.
