AIR SYSTEM Filed-Jan. 28, 1927 uucmfoz Patented Dec. 29, 1931 ANNA w. KEICHLINE, or IBELLEFONTE, rnnnmvmw rn AIR sws'mm Application filed January 28,- 1827.= Serial Nit-164365 The principal object of this invention is to provide means for heating a building by compressed air and also to use the air-for other purposes, such as in washing dishes I and clothes and as a cooling means.

Another object of the invention is to provide a vacuum system for cleaning purposes. This invention also consists in certain other features of construction and in the combination and arrangement of the several partsflto be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim, In describing my invention in detail, reference will be had to the accompanying draw: ing wherein like characters denote like or corresponding parts throughout the several views, and in which: 7

The figure is a more or less diagrammatic w view of the invention showing the compressor system, including a pipe line circuit, in which radiators are connected in series.

In the drawing, 1 indicates a compressed air tank and 2 a vacuum tank which are preferably located in the basement of a dwelling or other building and to which an air pump 3 is connected for filling the tank 1 with air and removing the air from the tank 2. The compressed air tank is connected by the pipes 4 with the radiators 5, so that the heat generated by compressing the air will radiate from the heaters and thus heat the rooms in which they are located. Coils formed by pipes 4: may be placed in stoves or fireplaces, 5 so as to have the air reheated bythe heat from these points as shown at 5'. After leaving the heaters the compressed air may be carried by the pipes 6 to the clothes Washer 7 and the dishwashing machine 8 so that the air escaping into said machines will agitate the water therein and thus washthe articles placed in the machines. Some of the air after it has become cool can be circulated through, allowed to expand in and escape from different points in coils 9 of refrigerator 10 to cool the same. The vacuum tank 2 is connected by the pipes 11 with the sockets 12 which are adapted to receive connections of a vacuum sweeping line which may be" used" for cleaning, the roomsjand articles therein; v I

A more detailed description of the application oftlie' compressed air at'th'e'se' several points is shown by the detail drawing and the following explanation The" heating as suggested at 5 is p'lish'ed by compressing the air in the tank 1 which is Well insulated and" utilizing, tlie l ieat of compression, by circulating the, air

through well insulated -pipes 4, and'the radiators 5" reheatingthe air by placing resistance coils 13 directly in the radiators and possibly by picking up heat from stoves and fireplaces, as at 5'. After air is used in the radiators it is carried on to perform other operations.

The radiator 5 is preferably formed with spaced inner and outer walls, the space between the walls being filled with some suitable heat-conducting material. The passage for the heated air is preferably of less diameter than that of the supply pipe which A conveys the heated air to the radiator. It

will further be observed that the end section of the radiators with which the supply pipe communicates has an electric resistance coil 13 arranged therein, so that the temperature of the air circulating in the system is boosted at the inlet to the radiators. I

Arrangement could be made to remove the heat-conducting material from the interior of. the radiator, so that the air being cooled during circulation on being allowed 2' to expand in these radiators would provide a means for cooling the houses in summer time. The scheme for ventilation would be to allow some of the compressed air to escape into the rooms. This air can be filtered and humidified on its return through the compressed air tank. The impure air of the rooms may be drawn off through the vacuum sweeping duct.

The cooling process for the refrigerator, as suggested at 10, is accomplished by having the air, after its circulation and passage through a valve to remove its moisture, ad-

mitted to the refrigerator and circulated through. coils 14:, which are immersed in water in a tank 15, the Water being agitated by final exhaust at 16.

It is thought from the foregoing descrip tion that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall Within the scope of the appended claim.

What I claim is In a compressed air system of the character described, a plurality of apartment heating radiators, a pipe line circuit connecting the radiators in series, an air compressor connected in said pipe line circuit for maintaining a constant Working pressure therewithin, an auxiliary heating means in the circuit at the inlet of each radiator to increase the temperature of the compressed air Within the respective radiators, whereby the temperature of the air at the inlet of each radiator may be economically raised for heating purposes and reduced to normal Working condition at the outlet thereof.

In testimony whereof I afiix my signature.
