RUDOLF BERG, OF PITTSBURG, PENNSYLVANIA, ASSIGNOR OF ONE-HALF TO'FERDINAND VVENIG, OF SAME PLACE.

'AIR COMPRESSING AND COOLING APPARATUS.

SPECIFICATION forming part of Letters Application filed March 24, 1898} To all whom it may concern;

' Be it known that I, RUDOLF BERG, a citizen of the Empire of Germany, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented new and useful Air Compressing and Cooling Apparatus, of

.which the following is a'specification.

' Myinvent-ion relates to certain new and use-' fnl improvements in air compressing and cool- The object of my invention isto construct anapparatus of this class which will absorbthe heat of the air while the same is being compressed.

My invention particularly relates to an air' compressing and cooling apparatus in which the heat of the air is rendered sensible at the stage of its compression and is absorbed by means of a seriesof disks or heat-absorbers suitably arranged therein, thereby cooling .the air.

. My invention further relates in providing an air compressing and cooling apparatus of this class with means whereby a series of disks or heat-absorbers are cooled by a continuous flow of water.

My invention further relates'in providing an apparatus of this class witha' compression-chamber having arranged therein apiston vat its lower end to agitate and force the water around and between the series of disks or heat-collectors,' whicli are arranged in the enlarged upper portion thereof.

To make the object of myinvention clear, I will state that when the air or gas is compressed the heat contained therein is rendered sensible; or, in other words, the temperature increases and so does the caloric intensity in the compression chamber. .To overcome this increased temperature or to absorb the heat or to cool the air while in the act of compression, I" provide the compression-chamber with'a series of disks or heatabsorbers',whichare suitably arranged therein for the purpose-of collecting or absorbing the heat rendered sensibleduring the stage of compression. These disks or heat-absorbers also divide the air into small parts, so the same will be thoroughly cooled while'passing between them Owing to'the continual flow Patent No. 626,883, dated June 13, 1899.

Serial No. 674,992. (No model.)

of water over the disks or heat-absorbers the same are always keptcool, and the absorbing of heat from the compressed air tained thereby. v

. My invention further relates in constructis readily obing an apparatus of this character which will compress the air, cool the same while compressing, and also expand the same simultaneously. Y

Briefly described,my invent-ion consistsof a compression chamber or cylinder, a piston operating therein, a seriesof. disks or heat-absorbers arranged in the compression chamber or cylinder, an expansion-chamber suitablyconnected thereto, and suitable operating means therefor.

My invention finally consists in the novel combination and arrangement of parts hereinafter more fully and specifically described, and particularly pointed out in the claim hereunto appended. v v

In describing the invention in detail reference is had to the accompanying drawings, forming'a part of this specification, wherein like letters of reference indicate corresponding parts throughout the several views thereof, and in which- 1 Figure 1 is a vertical sectional'view of my J improved air compressing and cooling-apparatus, an expansion machine or chamber connected thereto. Fig. 2 is a longitudinal section'al view of a modified form of compressing and cooling apparatus. Fig. 3 is a vertical sectional view of a modified form of an air compressing and cooling apparatus with a single-acting compression chamber or cylinder. Fig. 4 is a cross-sectional view of a modified form of an air-compressing and coolingapparatus. Fig. 5 is across-sectional View of a modified form of an air compressing and cooling apparatus with expansionchamber connected thereto. I 1

- Referring to the drawings by referenceletters, A indicates the casing of the air compressing and cooling apparatus, andBthe casing of the expansion-chambers, the same being suitably connected by the air-outlet pipe I). Arranged in the lower portion of the casing A are compression-chambers a 'and a within which is placed the water, andv secured to the sides of the casing A in any suitable manner; but I show in Fig. 2 the sides thereof apertured to receive the rods or screwthreaded collars surrounding this apertured portion.

For forcing the water upon the disks or heat-absorbers'A after it enters the 'chambers a and a I provide the piston P, having a piston-rod'P, the piston operating in the lower portion of the chambers a and a as shown in Fig. 1.

A and A are suction-valves used for the admission of air to the chambers a and a which is forced, in connection with the water,

by means of the. piston P, up and around the disks A and thence through the outlet-valves A and Ainto a discharge-chamber a". From there it is conducted by means of an outletpipe D to the expansion-chamber.

61. indicates an air-inlet pipe for the admission of air to the suction-chamber a From there it is taken by means of the suctionvalves A} and A as heretofore stated, into the chambers a and at a, indicates the water-inlet pipe, and d the outlet-pipe which is connected to the regulating-valve C. This regulating-valve consists of awater-chainber 0, formed by the casing c; the supporting-gu'ideways a which are formed integral withone side of the easing; the valve formed in the lower part of the support or guide 0 the float-valve 0 operating in the guide or support 0 ,the float 0 carried by the valve 0 the discharge-opening 0 which admits the water into thedischarge-chamber c and the outlet-pipe 0 It is readily apparent that by the use of this regulating-valve O a continuous flow of water from the discharge -chamber a is obtained. The operation of this valve can be readily understood.

The suction-valves are operated by the levers F and F, which are connected by the pit-man -rod E,carrying the eccentric E,whieh is operated by the shaft II and which is suitably secured thereto. 4

K indicates a crank, and J a crank-pin. It will' be readily observed that as the ec- F, which is connected thereto and which is v secured to the shaft carrying the lever F, the

served that owing to the connection of the crank K by the crank-pin J to the piston-rod the same are operated simultaneously.

The expansion machine or chambers B consist of a casing, as shown, having the aiminlets b and b andout-lets b and 6 having suitable valves mounted therein, as shown; These valves are of the Corliss type, and,

owing to their construction and the pressure of the air in the inlet and outlet passages, the regulation of the air passing therethrough is readily obtained.

Figs. 2 and 3 show a modified form of my improved air compressing and cooling appa' ratus with a single com pression-chamber and heat-collecting device, the samereference-letters being applied to the several parts thereof.

Fig. 4: is a modified form of difierential aircompressor, same reference-letters being applied to the several parts thereof.

Fig. 5 shows a modified form of air compressing and cooling apparatus with a single compressiomchamber and a modified form of expansion-chamber with suitable valves and operating mechanism B therefor. operating the mechanism in connection with this modified form of air compressing and cooling apparatus consists of a supply-valve B and exhaust-'valve'B which are operated by the leve rsB and B, secured to the shaft 13. These levers are operated by the con- The valve necting-rod, which is secured to the eccentric,

as heretofore stated. It will be readily observed that owing to the lever B having a pair of operating-arms and .whichoperates upon the springs B and B the valves areoperated alternately.

,1) indicates the air-inlet; b the air-receiving chamber; 17 the expansion -chamber;' bf, the exhaust-chamber,- and b the outlet therefor.

G indicates a steam-cylinder, G the inlet forthe steam, and g the outlet. P is a piston operating in the cylinder, and G the pis ton-rod. These parts are of any ordinary construction. 2

The operation of my improved air compressin g and coolingapparatus is as follows: When the shaft is operated by means of the pulley G, carrying the belt G, which is connected to the shaft H, the water T in the chambers 'a and a is, agitated and forced in the enlarged portions a and a thereby cooling the disks or heat-absorbers A contained therein, andin turn the air is admitted into these chambers, where it is compressed, and during this process of compression the heat contained therein isabsorbed, by the disks or heat-absorbers a From there it is conducted into the expansion-chamber by means of s It will it enters the discharge-chamber will pass into the discharge-pipe (Z, and thence outwardly through the regulating-valves C therefor.

It will be noted that various changesmay be made in the details of construction without departing from the general spirit of my invention.
