B 'm qwn ha mow Women of Fayette and f-.1 eiue iiifb lri flty a Stat ofKe'ntucky, have invented an Improveme'nt; infltefrigerating Apparatus, of which tbefollbwingisa specification y My i t n s c ice-,eoi'n pertinent in a refriger whicli the refijigeratiiig-vessel V l H outerwalhwhile the interwar and bottom are formed by, an internal partition, whose sidewalls inclo'se a receptacle in the middle ai ingvessel, of

of the refrigeratingvess'el which may be either vacant or used to contain salt, and whose bot tom ftsagaijnst the sides of the refrigerating vessel to onsnwreat bottom of the iee-co m-. Tlhe offlet piple' is open at the top, 5 aiild provided \vithseveral outlets, placed at partinen t.

different heights,forthe purpose of regulatingtheheight'at when the liquid that melts from the ice shall stand in the refrigeratingvessel, the offlet-pipe beingsurrounded by a loose casing-pipeibethe purpose of causing theliquidto 1 w off through the offletpipe from the bdttom of the refrigerating-yessel.

, In the acc'oinpanyingldrawings,"Figure11 is.

Figs. 9 and 10 represent the offlet-pipe, of which Fig. 9 is a plan, and Fig. 10 is a vertical section taken through the center of the same.

A is a refrigerator of any usual construction, having double walls filled between with non-conducting substance.

B is the refrigerating-vessel, constructed of sists in constructing an;

constitutes the any sheet metal; sloping from thetop with angle at the bottom. 0 is the intern walls a 0; and ,bottomb of the internal partition 0, and the sides of the refrigerating-vessel B. This receptacle incloses the salt-receptacle Yfinthe middle of the refrigeratingvessel B, which remains empty or contains salt, as is preferred. The arms at, together with the bottom I), fit upon the sides of the'refrigcrating-vessel B and keep the internal partition 0 firmlyin position. The bottom.extension piece 0 extends downward, in order, when salt is used, to prevent the salt from heaping around the offlet-pipe, and. obstructing it.)

In Fig. i one OflillQ side walls of the mgi f nal partition is represented as broken, in. order to show theconstruotion of the parti; tion 0 and in Fig. 2 the sides are broken,

in order to show the bottom b. Theside walls ot' the partition are pertbrated, for the purpose of admitting the passage ot'ai r from the receptacle Y, whenit isfree from salt, into the ice-receptacleX X, or. when. salt is placed in the recept'acle Y, to allow the interchange oi brinebe tween the ice and salt. .Insteadof the perforated sides, the walls of theinternal partition may be provided with adjustable pivoted slats, as in window blinds, which, by-

' being opened or closed, may regulate the coininunication betweeuthe salt-receptacle Y and the ice-receptacle X X, as is desired. p

D is the offlet-pipe, having the inlets 6 fig at diffterent height s,;and having the topjopen to admit of the oE-flow of theliquid from the melting ice at any height desired. The inlets e f g are stopped by the stoppers e f g. The offlet-pipe is surrounded by the loose pipe E, open at both ends, and having its top end higher than the top of the offlet-pipe,-for the purpose of causing the liquid from the melting of the ice to flow off from the bottom of the refrigerating-vessel B. r F is a partition dividingthe refrigerator into two compartments, A and A h is a tube inserted through the cover, immediately over the offlet-pipe l), for the purpose of admitting the external air. The air, being chilled in the offlet-pipe, descends into the refrigerator and al partition, constructed ,of p ag eet e l s dr m Th p ce or ice-receptacle X is formed by the side;

ventilates the compartment'A by passing out at the vent-hole k, and ventilates the compartment A by passing into it through the hole 0' in the partition F, and escaping through the vent-hole m.

The pipe E and the partition 0 separate the ice-box into two receptacles, X and X, and

prevent the ice from passing from one to the other.

My apparatus may be used either with ice only, or with ice and salt. In either method of use it presents great advantages. When ice only is used, an economy of ice is effected by the arrangement of the partition C, where by the ice is kept in the ice-receptacle X X, and excluded from the receptacle Y. The receptacle Y also admits the free circulation of air, which, having passed down through the ice, rises'up through the receptacle Y.

By the arrangement of the offlet-pipe l), and the construction of the ieereceptacleX X, the Water from the ice remains in the refrigen ating-vessel B, below the bottom of the icereceptacle, when the inlet 6 is open, and passes off from the bottom, Where it is warmest, after it has imparted its chill, thus utilizing the cold of the water, and economizing ice.

Salt may be usedwith this apparatus very conveniently. It may be placed with the ice, in the-usual manner, and the salt that wastes may beconvenien'tly shoveled up from the bottom of the retri'gerating-vessel through the receptacle Y; or, if desired, the receptacle Y may be filled to the top with salt. In this case, if the inlet 0 be open, the brine will standbelow the bottom of the ice-receptacle, and the ice and the salt will not act on each other, and the apparatus will have the refrigeratingforce of ice only. If the inlet 0 be stopped, the brine will rise to the inlet f, and thus come in contact with the 'ice and greatly increase its refrigerating-power. When the receptacle Y is filled with salt, the higher the brine stands in the refrigerating-vessel the greater the refrigerating-force. By means of the several inlets into the offletpi pc the height of the brine may be regulated, so as to obtain any degree of refrigeration desired.

'In Sheet 2, Figs. 4, 5, and 6, a modification of the apparatus is represented as applicable to a body-cooler.

G is a platform of sheet metal, on which the body lies. H H are cross-bars, which support the refrigerating-vessel. A is the top of the cooler-box, having in it the glass 10, through which the body may be observed.

In this the sides of the refrigerating-vessel B have an obtuse angle at the bottom, for the purpose of elongating the refrigerating-vessel. The internal partition 0 is also modified by having the bottom I) extend within the side pieces a a, so as to 'form, in connection with the side pieces a a and the side pieces S S, the salt-boxes Z Z, between the receptacle Y and the ice-receptacle XX. The salt which wastes and falls upon the bottom of the refrigeratin g-vessel B may be dipped, as before, from the bottom through the receptacle Y. In this arrangement the ice-receptacles X X remain wholly unmodified.

In Sheet 3, Figs. 7 and 8, a further modification of the internal partition 0 is represented. The bottom piece I) is placed higher on one side than the other, which arrangement raises the bottom of the ice-box higher in the receptacle X than the bottom of the receptacle X, so that when the brine is standing atthe level of the inlet fot the offlet-pipe, the ice in the receptacle X is resting in the brine, and imparts to the compartment A of the refrigerator the excessive cold of ice and salt, While the ice in the receptacle X is above the brine, and imparts to the compartment A the chill of ice only.

In these figures of Sheet 3, the drawings are on a smaller scale, the refrigerating-vessel being applied to a large house or railroad-car, and occupying one side with its length, being adapted to contain a large quantity of refrigerating materials. In all the figures the icereceptacles are substantially the same in ar rangement and construction.

What I claim as new is 1. The combination, with the refrigeratingvessel B, of the internal partition U, ice-receptacle X X, salt-receptacle Y, offlet-pipe D, inlets e f g, casing-pipe E, and refrigerator-box A, substantially as described.

-2. The combination, with the refrigeratingvessel B, of the ice-receptacle X X, as and for the purposes set forth.

3. In a refrigerating apparatus, the offletpipe D, inlets e f g, stoppers e f g, and casing-pipe 'E, as and for the purposes set forth.
