REFRIGERATOR-BUILDING.

SPECIFICATION forming part of Letters Patent No. 322,446, dated July 21, 1885.

Application filed April 29, 1 885. (No model.)

To all whom it may concern.-

Be it known that I, J OSEPH FRANCIS HAN- RAHAN, of Ottawa, in the county of Carleton, Ontario, Canada, have invented certain new 5 and useful Improvements in Refrigerators and Refrigerator-Buildings, of which the following is a specification.

My invention relates to refrigerators and refrigerator-buildings; and it consists in anovel construction and arrangement of the same, as hereinafter fully set forth.

In the drawings, Figure 1 is a longitudinal central section of myimproved refrigeratorbuilding. Fig. 2 is a transverse section of the I 5 same, and Fig. 3 an enlarged sectional view.

This invention is designed as an improvement upon that for which Letters Patent of the United States were granted to me, bearing date November 4, 1884, No. 307,459; and

the invention has for its object toimprove the circulation of air in the ice and refrigerating or cooling chambers. a

A indicates the icc-chamber, which is shown in Figs. 1 and 3, supplied with ice, and B the cooling-chamber, the two chambers being connected by a pipe or conductor, 0, extending from the top of the cooling-chamber to near the top of the ice-chamber, as in the patent hereinbefore referred to.

u The floor of the ice-chamberAis double that is to say, it is provided with two sets of parallel passages or channels, the upper set being separated from the lower set in a manner now to be described. Upon a suitable foundation, a, for the building are placed on edge the joists or timbers b, which extendlengthwise of the chamber A,as shown in Figs. 1 and 3, similar boards or planks, 0, being laid longitudinally across the tops of eachal- 4o ternate pair of joists or timbers I), thus form'- ing a series of parallel long rectangular channels or passages, 11. Upon the planks c, and lapping the adjacent edges thereof, are joists or timbers e, which are of the same length as the other floor-timbers, and which form the tops of similar channels or passages, d, which are in all substantial respects the same as the adjoining channels. Immediately above the timbers b, and resting upon the timbers e, are joists or timbers, f, which, extending parallel with each other, longitudinally of the building, inclose or form the side walls of a second set of passages or channels, (I, which latter are above and of the same size and form as the lower channels or I passages. It will thus be seen that the floor is composed of two a 1 sets of passages or channels,d, both extending lengthwise of the building, and one set being immediately over the other set. The passages d are open at both ends, and communicate 6o sages g at two sides of the chamber A, I d0 not wish to limit myself to this arrangement, as it is obvious that they may be applied to only one side or to all the sides. 7 The inner upright faces of the channels or ducts g and the upper faces of the upper set of channels (1 are left'open until theice isput in place, when they are closed by the ice,which consequently forms one side of each of the vertical ducts or channels 9 and of the upper set of channels d. From this construction and arrangement it will be seen that the air in passing through the ducts or passages d 9 will pass in contact with the ice.

The passages (Z are furnished with doors or shutters h, as shown in Fig. 1, by which to vary or reverse the currents of air.

The conductor or pipe 0 connecting the chambers A B may enter the former at the ceiling-line, as in Figs. 2 and 3; or it may enter the chamber at apoint somewhat lower, as in Fig. 1, in which latter case it will be found advisable, if not necessary, to employ a short vertical continuation,0,which shall extend up along the wall of chamber A and deliver the air near the ceiling.

The walls z of the whole structure are rendered non-conducting by any usual and wellknown material, such as sawdust. I

D D indicate ventilators in the roof of the ice-chamber A, which ventilators may be of any desired form. They communicate with the chamber A by means of vertical tubes or pipes E and F, (shownin Figs. 1 and 2,) said tubes being of about the same area in crosssection as the tube or conductor 0. It will be noticed that the air-inlet pipe E descends nearer to the surface of the ice than does the discharge-pipe F, and both may, if desired, be provided with valves to regulate the air-currents.

The ice-chamber A is supplied with ice nearly to the ceiling, as indicated in all the figures, and the articles to be preserved or cooled are placed in chamber B.

The space above the ice allows a current of cold air to pass downward through the vertical flues g in contact with the ice forming one face of said fines, and thence horizontally beneath and in contact with the ice through channels or passages d, and into the refrigerating or cooling chamber B. The air also descends through the vertical flues g that are adjacent to the chamber B, and discharges into the horizontal ducts d. As the cold air enters the refrigerating or storing chamber B it becomes warmed by absorbing the heat from the articles placed in said chamber, and, being thus rarefied, rises and escapes with whatever odors there may be through the pipe or conductor 0 into the top of chamber A. A portion of the heated air escapes through the outlet or Ventilating pipe F into the atmosphere, as indicated by the arrows in Fig. l,while the remaining lesser portion will pass I over the ice and down through the ducts 9,

and again delivered to the cooling chamber B through channels d. An amount of air enters through pipe E equal to that which escapes through pipe F, thereby maintaining a constant circulation of air through and around the chambers A and B. As the heated or warmed air escapes from chamber B into chamher A a part passes up through pipe F and the remainder passes to the farther side of the chamber A, where it meets the incoming .current of fresh air discharged by pipe E. In

order to prevent the warmed air from passing up through pipe E, and thereby destroying the perfect circulation, said pipe E extends downward below the warm-air strata and discharges the cold air below the latter. This arrangement causes whatever warmed air passes over to the farther side of the ice-chamber to descend with the fresh cooler air down through the ducts g.

The shutters or valves it applied to the discharge-mouths of the channels or passages (1 may, and preferably will, be made as one continuous shutter, so that all the upper row or all the lower row of passages d may be closed, as desired.

The air in passing through the channels 9 and d in contact with the ice absorbs more or less moisture therefrom, and hence when it is desired that the air delivered into chamber B be particularly dry the valves h on the upper row of passages or channels are closed and the air made to pass through the bottom row, which is not in contact with the ice.

The foundation (4 may be made of stone, cement, concrete, or other material that will prevent the water passing through it.

The water resulting from the melting of the ice will pass along the channels or passages d, and be discharged into a gutter, j, (shown in Fig. 3,) and by which it is discharged from the building. This gutter j may be tapped or kept normally closed at its discharge end, so as to prevent the ingress or escape of air to or from the chamber B, and thereby destroy or interfere with the circulation.

The manner of building up the double floor for the ice-chamber A may be considerably varied; but I prefer the arrangement shown, as it is strong and is found to answer the purpose admirably.

I am aware that it has been proposed to construct a refrigerator-building with two sets of double walls with continuous-air-fiues between them, and such construction I do not claim.

Having thus described my invention, what I claim is 1. In a refrigerator, the combination of an ice-chamber, a cooling chamber communicating therewith at the top and bottom, and an air inlet, and an air-discharge pipe in the top of the ice-chamber communicating with the atmosphere, as and for the purpose described.

2. In a refrigerator, the combination of an ice-chamber and a cooling-chamber communicating therewith, an air inlet pipe, and an air-discharge pipe in the top of the ice-chamher and communicating with the atmosphere, said air-inlet pipe extending downward to a point below the air-discharge pipe, for the purpose set forth.

3. In a refrigerator, the combination, with an ice-chamber and a cooling-chamber communicating therewith, of .the two sets of fines or passages d, arranged one above the other and communicating with the ice and cooling chambers.

4. In a refrigerator, the combination, with an ice-chamber and a cooling-chamber communicating therewith, of the two sets of fines or passages d, arranged one above the other and provided with valves or shut-ters h, as and for the purpose set forth.

5. In a refrigerator, the combination of an ice-chamber, a cooling-chamber, an air-duct extending from the top of the cooling-chamber to the upper side of the ice-chamber, Vertiealfiues at one or more sides of the icechamber, on the interior thereof, and horizontal flues beneath the ice and communicating with the vertical flues and with the coolingchamber, as described and shown.

6. In a refrigerator, the combination of an ice-chamber and a cooling chamber communicating therewith, vertical flues 9 open at theii ends and one side, and horizontal g and d, chamber B, and pipe 0, connecting fines d, communicating with the flues g and the chambers A B, as and for the purpose set 10 with the cooling-chamber, and also open at forth.

one side whereby the air in passing through said flues is in contact with the mass of ice. JOSEPH FRANCIS HANRAHAN 7. The herein-described refrigerator, eonsist- Witnesses:
