COMPRESSOR.

Original No. 1,883,860, dated July 5, 1921, Serial No. 357,485, filed February 9, 1920. Application for reissue filed June 27, 1923. Serial No. 648,115.

To all whom it may concem:

Be it known that I, ADOLF Roszxowsm, a subject of Russia, residing at New York, county of New York, and State of New Yor have invented certain new and useful Improvements in Compressors, of which the following is a full, clear, and exact description. This invention relates to an improvement in automatic air compressor apparatus, designated particularly for use with an im proved compressed air supply system for railroad stations forming the'subject matter of Patent No. 1,240,373 issued to me Se tember 18, 1917.

riefly, such system comprises reservoirs containin water and compressed air located beneath t 1e surface of the ground at the water station, the reservoirs being connected with each other, with a more or less remote pump stationfor the supply of water and air to such reservoirs, an with a standpipe outlet from which the water is withdrawn for use. A particular valve arrangement between the reservoirs, supply and service pipes renders the system self distributing and self regulating.

The system contemplates the continued use ofthe compressed air of the reservoirs, that is the use of such air as a motive force for the water to a low limit of pressure of such air and the restoration of the maximum air pressure through an additional supply of water from the pump station.

In the practical use of such system, however, it has been found that there is a distinct but slow dissolution of the compressed air in the water, and as such is lost for effective uses, it must be compensated for, preferably by replacement. a. The present invention is designed to pro vide an apparatus for the automatic replacement of such dissolved or absorbed portion of the compressed air, and in more specific detail comprises two comparatively small tanks preferably located at or near the pump station of the system and on a level below that of the reservoirs. Two-way valves, con

nected for simultaneous but reverse action, are provided, either serving to connect a particular tank with the water pipe from the reservoir and air pipe thereto, while the other at the same time connects the other tank, at both inlet and outlet with the atmosphere. The reservoir connected tank,

which by a previous position of the valve incident to the difference in level, 'and the contained air forced into the system. The other tank, which in the previous position of the valves has gradually filled with water from the reservoirs in forcing the air therefrom into the system, is the present position of the valves, open to the atmos here, draining it of water and, of course, llingit with air under atmospheric pressure to be forced into the system when the valves are reversed.

In the drawings:

Fig. 1 is a view illustrating more or less diagrammatically the improved compressor apparatus.

Fig. 2 is a section of the valve.

The improved construction com rises two air receiving tanks, 1 and 2, pref rably located near the pump station A of the'im-. proved system, and on a level below the water storage or service reservoirs B of such system to provide a head of water from the service reservoirs to the tanks. through the pipe 3, leading from such ser ice reservoirs.

An air supply pipe 4 leads to the air pressure pipe 4"I'or serving the reservoirs, and this pipe has a valve 5 which opens toward the reservoirs.

Tank'l has an air pipe 6 opening therefrom near the top with a waterexcluding valve 7 at the entrant end thereof, and also a water pipe 8 opening therefrom near the bottom; while tank 2 has exactly similar The respective valve casings 17 and 18,

are each provided with a port 19, lead,ing

to the atmosphere, the casing 17 or valve 12 having ports 20 and 21 for the connect ing thereto of the air pipes 6 and 9 of the respective tanks, and another 'port 22 for the connection of the air supply pipe 4. The

casing 18 of valve 13 has similar orts, that is ports 23, 24 for connection of t e respective water pipes 8 and 11 of the tanks 1 and 2, and a port 25 to which the pipe 3 is connected.

The passages 14 and 15 of the valves are so relatively disposed that in one pos tion for example that illustrated in the drawings, the air and water pipes of tank are open to the atmosphere, and hence th1s tank is charged with air under atmospheric pressure. The air and water pipes of tank 2, however, are in this position of the valves connected with the water pipe 3 and air supply pipe 4 of the system. The water under the head described, will force the an from tank into the system to replenish the absorbed air. stantially filled with water, as may be 1nd1- cated as an external gage 26, the valves are operated bymeans 16 to reverse them, utilizing tank 1 as the serv1ce tank, and opening tank 2 to the atmosphere for drainage of the water therefrom and replacement of such water with air for charging purposes on the next operation of the valves. v

Beyond the mere change of the valves, the compressor apparatus is entirely automatic in its operation, and will effectively maintain a, constant air' volume in the system.

It is obvious that the invention is not limited to the use of two airtanks, but is applicable to. the use of one or more air tanks depending on the needs of the system. If but one tank, such as tank 1, only be required, the ports 21 and 24 of valve casings 17 and 18 can be omitted. The controlling mechanism can be operated to simply disconnect tank 1 from the water pressure ipe 3 and the air supply 4,. while thetan is vented to atmosphere and drained. This arrangement is shown in Fig. 1. Then the valves 12 and 13 can be turned simultaneously to disconnect the tank 1 from atmosphere and to connect the tank 1 with the water pressure pipe 3 and the air pipe 4. After air in tank 1 has been forced by direct "contact with water from the water pressure pipe 3 into the storage reservoirs B, the valves 12 and 13 can be returned to thepositions shown in Fig. 1 in order that the tank 1 may receive air, awaiting the time when again necessary to supply air to the storage reservoir.

In other words, there are certain features of the invention which are'presentregardless of whether one or a p urality of .air tanks are employed. Considering the operations performed by the. controlling mechanism in cooperation with an one of the tanks, the invention provides air charging apparatus which can be rendered operative to introduce air into the water system while the connection between the pump and When tank 2 has become subwater reservoir is maintained. The air is forced from a tank into the water system by direct contact with a body of water under pressure thereb reducing the number of moving parts to t e minimum. The valve mechanism is controlled by a single manually operable member which, in one position, causes a tank to be drained and filledwith air and, in another position, causes the tank to be connected with the water system.

While the form of mechanism herein shown and described constitutes a preferred embodiment of one form of invention, it is to be understood that other forms might be ado ted and various changes and alterations ma e in the shape, size, and proportion of the elements therein without departing from the spirit and scope of the invention.
