CHARLES r. l AIGE, or DENVER, COLORADO.

REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 470,167, dated March 1, 1892.

Application filed May 19. 1891.

To all whom it may concern:

Be it known that I, CHARLES l PAIGE, a citi-" zen of the United States of America, residing at Denver, in the county of Arapahoc and State of Colorado, have invented certain new and useful Improvements in Ref rigeratms; and I.

vent the accumulation of ice or frost .upon the pipes through which the cooling-liquid is forced. These pipes being cooled below the freezing-point, the surrounding moisture naturally collects thereon in a congealed or solidi-v fied. form. As this incrustation thickens, a

blanket, so to speak, is formed around the pipes, rendering them practically useless for refrigerating purposes.

In my improved construction the uppermost pipe is perforated and contains salt-wa-.

ter or other suitable liquid under pressure. The pipes below the perforated pipe are so arranged and supported in connection with drip-brackets that as the liquid passes from the perforated pipe it drips over the whole series of pipes in succession and finally passes into a. trough at the bottom of the series,

whence it is conducted to anv suitable receprefrigerator.

tacle.

My-improvcd construction will be fully understood by reference to the accompanying drawings, wherein is illustrated an embodiment of my invention.

In the drawings, Figure 1 is a vertical section taken through the upper portion of the Fig. 2 is a similar view of a. modified form of construction. Fig. 3 is a fragmentary view, taken on an enlarged scale, of the mechanism shown in Fig. 1. Fig. 4'isa longitudinal section taken on thelinewm, hig.

1, the pipes being shown in elevation.

In the views, wherein similar reference characters designate corresponding parts of the mechanism, let the numeral designate the outer walls of the refrigerator, which are constructed in the usual. way. Within these Serial No. 393,343. No model.)

walls and in the upper portion of the chamber are located the interior walls 15, forming a.double-inclined flue or air-conduit 20, the inner wall of which forms an apex at the top, The conduit opens at both extremities into the'chamber below,thus giving a free circulation for the air from chamber 25 through the flue 20 and'back again to the chamber.

In order to increase the cooling-s11 rface over which the air passes, it is preferable to arrange the cooling pipes on an inclined plane formed by one side of the inner wall 15,

to which are secured brackets 35, composed of a suitable seatgtO, upon which the pipe 30 rests, and an inclined drip-plate above this seat and terminating, preferably, directly above the center of the pipe, the seat and the drip-plate being connected by the web '50 of the b racket, through which portion thebracket is bolted or otherwise suitably secured to the wall 15, asshown.

The perforated pipe is located and suitably secured above the inclined series of cooling-pipes. Above this perforated pipe and almost "in contact therewith is a plate 60, having downwardly-inchned sides adapted to throw the liquid issuing from the pipe back on itself and thence to the first pipe 30 of the inclined series below, whence it is guided by the first drlp-plate to the next pipe of the se-" ries, and so on to the last, whence it passes to a trough 65.

' Another arrangement of pipes and dripplatcs is shown in Fig. 2. cooling-pipes 30 are arranged in two vertical air-flue 70, connected with lines 75, leading from the main chamber 25. The pipes 30 in this modified form are supported by brackpts- 80, secured to the walls of the air-flue.

In this figure the series on opposite sides of a central vertical the opposite side of the flue from each pipe 30 and somewhat higher than the pipe is socured a downwardly-inclined drip-plate 85, provided with. a suitable supporting-brace. The perforated pipe 55 is supported above the vertical air-flue 70, so that the liquid escapin g therefrom shall fall on the first drip-plate 85, whence it is conducted to the pipe 30 on the opposite wall of the air-flue, and from this pipe to the next drip-plate below, and so on until the lowest pipe is reached, when this liquid is conducted into a trough 90. It will thus be observed that by this simple construotion salt-water or other suitable liquid may be dripped over the pipes continually, whereby the usual incrustation resulting from congealed moisture is obviated, while the increased cooling-surface aflorded by the dripplates is an important feature.

It may be well to state that all parts of the mechanism exposed to moisture or liquid should be constructed of some non-corrodible metal, as galvanized iron.

Having thus (1 ribed my invention,what

1 claim is- 1. In a refrigerator, the combination of a series of'oooling-pipes arranged in the upper portion thereof, of a perforated non-congealable liqnid-containin g drip-pipe located above the cooling-pipes, and downwardly-inclined drip-plates secured to the walls supporting the pipes and so arranged with reference to the pipes that the liquid from the drip-pipe is conducted successively to the cooling-pipes of the series, substantially as and for the purpose sctforth. a

2. In a refrigerator, the combination, with the cooli ngpipes, of brackets, each consisting of a seat and a downwardly-inclined drip' plate above said seat, and a non-congealable liquid-supply source-located above the brackets, the brackets being so arrauged that the liquid falling from'said source is conducted v to the cooling-pipes successiyely, substantially as and for the purpose set forth.

In testimony whereof I afiix my signaturein presence of two witnesses. Cl IARLES l PAIGE.
