COOLING AND REFRIG- ERATING SYSTEM.

Application filed January This invention relates to. improvements in a cooling and refrigerator system, and has for its object to provide a system not requiring the use of ice. I Another object of this, invention is to provide in a cooling and refrigerating system, a

suitable compartment, and means for. creatin a rapid evaporation of water.

A still further object of this invention is to provide in a cooling and refrigerating system, a series of curtains and means where by the curtains may be kept moist through their entire surfaces.

A further object of this invention is to provide in a cooling and refrigerating system, curtains and means for keeping said curtains thoroughly wet, and means for continuously forcing air currents substantially over the entire surfaces of said curtains.

A still further object of this invention is to provide in a cooling and refrigerating system requiring compressed air for causing rapid evaporation of moisture, a means for cooling said air.

. lVith the foregoing .and other objects in view, I have invented the system illustrated in the accompanying drawings, in which:

Figure 1 is a vertical sectional view of a refrigerating room embracing my invention.

Figure 2 is-a section at line 2-2 thereof;

Figure 3 is a detail longitudinal sectional view of a water supply tank;

Figure A is a section on line, 4-4 thereof;

Figure 5-is a detail of a side elevational view of a valve member; and

Figure 6 is an enlarged detail section of a gutter.

Like reference characters indicate like parts throughout the several views of the drawings and in the specification, in which 1 indicates a refrigerating room having a gutter 2, extending entirely therearound. From this gutter is suspended a series of ourtains 8, i and 5, by means of hooks 6 and 6 attached thereto, at suitable intervals adjacent but spaced apart from the upper edge thereof. These hooks 6 and 6' are adapted to enga e over the edges 7 on the roll of the edge 8 of the gutters 2 and on the edge 7 of gutter 15. The portion 9 of the, said curtains, above the hooks 6, are adapted to lie loosely over said roll 8 and into the bottom 1 of the gutter 2. It is to be noted at this point that the curtains are not stretchedin any direction over the roll 8, but by means 9, 1925. Serial No. 1,417.

the curtains taut over the roll 8 of the gut ter 2, thus permitting the curtains .to readily absorb the water and siphon .it from the curtains saturated at all times. Mounted behind the curtains 8, 4: and 5, and substantially there-against, are a series of horizontally disposed backpipes 10, each having a series of suitably spaced apart nozzles v11, projecting toward the curtains. Thesepipes 10 are connected to anair supply pipe line 12, through valves 13, in order to, control the supply of airto each of the horizontal pipes, The lower edges 14: of the curtains depend intoa gutter 15, which inclines toward awater inlet pipe 16'of the watersupply tank 17, so that any water draining upon the curtains will return to the tank 17 from which it is originally supplied to the gutter 2, in the manner presently to. be explained.

The principal purpose of the gutter 15,. in conjunction with the gutter 2, is that both the upper and lower edges of the curtains 3, 4: and 5 are immersed in water in said gutters to a, sufficient extent in order to insure complete saturation of the curtains at all times whereby an air seal is provided which will prevent air from: the pipes from escaping over or around the edges of the curtain into the refrigerating'or cooling room, thus necessitating all air from the air pipes passing directly through the interstices of the saturated curtain in order to provi'de'rapid evaporation of the moisture in the curtain.

A further water supply to the gutterlti may be provided through a faucet 18. A series of spaced apart uprights 19, terminating in curved upper edges 20, form supports for the screen sections 21, which enclose the curtains and air pipes above described. Mounted outwardly of these screens are a series of batten frames 22, for protecting said screens from the contents of the refrigerating room.

17 is an airtight tank for containing water under air pressure, whereby the same may gutter, to a sufficient extent to keep the entire be supplied to the gutter-2,by automatic means now-to be explained. 'Mounted within the tank 17, is an upright rod 23' over which is movably mounted a tube 24, having a fixed collar adjacent its lower end, and a head 26 on its upperend. Loosely mounted over the tube 24 is a float 27, which, when the. tank is full, will bear against the head 26 and raise the tube '24, operating toggles 23 and 29, on the lower end of tube 24 which are pivoted to the inner ends of

levers

30 and 31, both of which are pivoted upon fulcrums 32 and 33 respectively. Mounted upon the outer end of the lever 30 is a closure valve 34 for the inlet 35 of the water supply pipe 16 in the gutter 15. Pivoted. to the toggle 28 is the inner end of the lever 30. The inner end of lever 31 is pivoted to toggle 29 as at 36 The outer end of lever 31 is pivoted at 37 to link 38, the upper end of which is pivoted to the arm 39 on the valve plate 40, which plate is provided in its inner surface with an elongated groove 41. The groove 41 in the position as shown in the drawing is adapted to connect the ports 42, 46 and 47, in disc 44. The ports 42 and 46 are supplied by a pipe line 48with air from an air compresser (not shown), while the port 47 is connected with the supply pipe 12 for the blow pipes 10. In another position the valve plate 40, which is pivotally mounted at 45, is adapted to connect the opening 43, in plate 40, with the port 42 in the disc 44. It is to be noted at this point that the air will steadily pass from port 46, all along the elongated groove 41 to the outlet port 47 and supply pipes 12 and 10. When the water in the tank 17 has risen to its predetermined capacity, the float 27 bearing against the head 26 raises the tube 24 where the toggles 28 and 29 are pivoted, the toggle 28 to inner end of lever 30, causing the valve 34, mounted on the outer end of the lever to close port 35, to prevent outflow of water from said port. At the'same time the toggle 29 lifts the inner end of lever 31, forcing outer end 31 down, causing the link 38 to draw down the arm 39 to connect the ports 42 and 43, to admit compressed air into the upper part 49 of the tank, by means of which the water therein will be forced out through the port 50 into a pipe51 which supplies the gutter 2. As soon as the water in the tank falls to a level to permit the float 27 (shown dotted in its lower position) to seat upon the collar 25, forcing the tube 24 to its lowermost position which operates the toggles 2S and 29, the operation of the

levers

30 and 31 are reversed closing the compressed air inlet port 43, and opening the water inlet port 35, in order to permit the tank to refill as shown by the drawing. Thus, it will be seen that thesupply of water to the gutter 2 is automatic. Fixed to the arm 39 is a rod 52, carrying a. closure valve 53 which, when lowered, opens the port 54 to permit the escape of air from the tank 17 when filling. When the arm 39 is drawn down by the link 38, the valve is caused to close the inlet 54. V

The automatic means for supplying water for the curtains is the tank 17 above described, and isfor use in refrigerating and of water to kee curtains saturated, to continually flow tierethrough, and down the curtains to gutter 15, from where the surface water is drawn by pipe 16.

60 is a compressed air cooler, through which compressed air is run from an air compressor (not shown), in order that the heated compressed air may be cooled before being allowed to enter the tank 17. If tank 17 is omitted, the air will pass directly from pipe 58 to pipe 12.

Having described my invention that which 7 I claim to be new and desire to procureby Letters Patent is: y
