subways l have devised the system of air factory conditions of thejetmosphere in such purification to be herein" described and-which may be briefi'y set forth es follows: Air'is taken from the atmosphere exterior of the subwayet as high a polrit above the earth as practicable, compressed to e high pressure, then passed throughcooling coils fo'r'the pure pose of reducing the heat-.ofthe air, which,.
under compression, has become sensible heat, toil'atent heat, or, in other words, toat'm'os pheric temperature. The compressed and cooled air is then delivered into a storage reservoir and from said storage reservoir-is conducted to a. distribution point. At this last named point the air enters int'o'expansion pipes situated in the subway and open to comfnunication therewith. sion pipes are controlled. by ex )ansion valves and: they are continued. to su', 'cient lengths in the subway to afford refrigerating surfaces to coolthe air inthe subway by the absorption of heat therefrom and due to the exponsioriofthe..compressed air while escaplng through the expansion valves into the expansion'pipes. The air, as it escapesinto the subway and mixes with the air pre- The expan- I viously present thereiinstill retains the power of abstracting heat from-the air resent in the subway and itis quickly (istributed throughout the subway due to, the continual disturbance of. air. in such'sub' wey caused" by the passing railroad cars that act to iniand ceuse iuropby the suction ocrnent of the cars.

is in part an enlarged top or plan view of one of the expansion pipes utilized in the ap aratus and in art a cross section throng i the header to W ich the series of expansion pipes are connected. Fig. VI is a perspective view of a subway partly broken out and m apparatus therein.
In the accompanying drawings: 1 designates an air supply pipe that is open at its upper end and extends to a sufficient height in the open atmosphere to receive the air that is to be passed through the apparatus. This supply pipe leads to an air compressor :2 of any ordinary description that is operated by a suitable engine 3. V
4 is a conducting pipe leading from the air compressor and through which compressed air is delivered to a cooling coil 5.
For the purpose of reducing the temperature of the compressed air to atmospheric temperature instead of sensible heat while passing through the cooling coil, I mount above the cooling coil a series of drip pans 6 from which a flow of water may constantly descend upon the cooling coil and fall into a catch basin 7. The cooling coil preferably consists of a plurality of coiled )ipe sections that are united at their inlet ends to a header to which the conductinv pipe 4 extends while the outlet ends, of tie coils are connected to a header 5".
8 is a conducting pipe leading from the header 5.
9 desi nates a storage reservoir to which the conducting pipe,8 is connected and in which the cooled compressed air is stored. v
10 are receivers having communication with the storage reservoir and which are intended to be cut off, when desired, from such communication bv valves 11. These receiversare provided with drain cocks 12.-
The receivers are designed to be normally in communication with the storage reservoir in order that the condensed moisture that enters into the storage reservoir may be drained therefrom into the receivers. This moisture which is condensed by the compression of the air absorbs many impurities in the air that are soluble in water and consequently by delivering the moisture into "the receivers it is removed from the circuit traversed by the air flowing through the apparatus in order that the impuritiesmay not e again taken up by the air.
13 designates a main leading from the the flow oflair from the storage reservoir to the main may be controlled. The main 13 leads into the subway in which the air is to be purified and it has connected to it any desirable number of headers 15 in which are cut-off valves 16.
17 are ex ansion valves connected to the headers, an 18 are ex ansion pipes connected to said valves and aving greater interior area than the ports in said valves. The expansion pipes are suitably supported in the subway, within which the air is to be purified, and they are open at their ends farthestremoved from the expansion valves in order that the air may escape freely through said open ends into the subway to be distributed therein for the purification of the foul air in the subway.
I claim:
