This invention relates to air compressors, and has particular reference to the method and means for cooling compressed air which is to be used with pneumatic tools.
The invention is particularly applicable to portable air compressors which are usual 1y mounted on wheels in the form of a truck, and are conveyed from place to place where compressed air is required for operating purposes. V 1
The portable air compressor is, therefore, used, as it were, in the field, and therefore away from cold water. From the standpoint of cooling it, therefore,presents different problems than the stationary compressor.
On the portable compressor, the water is limited to the water in the engineradiator and cooling system and, consequently, there is no cold water available for cooling the air.
The air from the compressor is ordinarily supplied to the tools through-a rubber hose and when the air is very hot, the same has a deleterious effect upon the rubber and deteriorates the same to such an extent that its life is quite limited. I
The present invention has for its object the method and means for cooling air compressed by a portable compressor.
A further object of the invention is to cool I the air to such an extent that it will not deteriorate rubber hose through which it is conveyed.
A still further object of the invention is to provide means by which the air can be cooled without any expense other than the inaround said coils and thus cool the compressed air in said'coils.
' The drawings illustrate an embodiment of the invention and the views therein are as follows:
Figure 1 is a side elevational view of a portable compressor in dotted lines and with the mechanism of the invention shown in full lines, and
FigureQ is a front view similarly illus- V trated.' i V Inthedrawings, 6 represents the engine and 7 the air compressor. The crank shaft f theengine is provided with the usual fan 9' which is located directly 'behind the usual radiator l1 which is connected to the water-cooling system of :the engine 6 and compressor 7. r' r Theair compressed by the compressorl'i delivered 'into a' supply tank 12 which is 10 cated 'at anyconvenient'pointon the compressor, and 1n the present instance the compressor, as a whole, is mounted on wheels 13 and the radiator is at the frontof the device and v the supply tank Eat the rear.
Leading from the supply tank 12 is a pipe 14 which extends to a series of pipe coils 16 mounteddirectly infront of theface of the,
water radiator lland forming an air radia- The'se coils are set two and one-half or 'three inches in front of the face ofthe'ra diator 11 and the final leg is provided with a pair of cocks 1 7'which have coupling ends of a hose which is intended to convey the com-,
pressed air to the tool at the other end of said hose (not shown). 7
-18 for receiving 'theinterfitting partof a coupler": (not shown) mounted on the end The coils are mountedin any convenient V 7 way, such as by the straps 19, and the number of pipes in each coil will depend entirely upon the temperature required.
. Assuming that the engine and compressor are in operation, andrthewater circulating through the radiator 11, if the air compressed .-be at a temperature of pounds per square inch, it has been found that the temperature of the air in the tank 12 is approximately 285 F. This temperature is very hard to Work with and is quite damaging to the rubber hose. By a method and means such as that shown fill in the drawings, it is found that the temperature of the air will be reduced to approximately 135 F. which temperature is low enough so that it will have no deteriorating effect upon the rubber hose.
As the fan 9 is rapidly rotated by the crank shaft 8, air from the atmosphere will be drawn through the radiator 11 which is of honey-comb construction, and by placing the compressed air pipe in front of the radiator, the atmospheric air will be drawn over and around the pipe coils 16 and will thus materially reduce the temperature of the air therein, while experiment has proven that there is little, if any, increase in the temperature of the water in the water-co0ling system.
The location otthe pipe coils in front of the radiator also serves as a guard to prevent injury to the said radiator and, therefore, take the place of the usual guard which is placed on portable compressors of this type.
Of course, the compressor illustrated may be modified in various ways without departing from the invention herein set forth and hereafter claimed.
The invention is hereby claimed as follows:
1. An air compressor organization comprising a compressor unit, means to provide a circulation of air, a storage tank for the compressed air, a hose connection, and a con duit from the storage tank to the hose connect-ion following a tortuous path through the area of air circulation.
2. A compressor organization comp-rising a compressor unit, a fan, means to operate the compressor and fan, a storage tank in direct communication with the compressor unit, a hose connection, and a conduit extending from the tank to the hose connection following a tortuous path adjacent to the fan. 7
3. A compressor organization comprising a compressor unit, a storage tank in direct communication with the compressor unit, a hose connection, a conduit extending ironithe tank to said hose connection and provided with a tortuous area, and a fan operated in conjunction with the compressor unit tending to circulate air over the said tortuous area of the conduit.
In testimony whereof I have signed my name to this specification.
HENRY DRUSCHEL.
