BALTIMORE, MARYLAND.

REFRIGERATOR.

SPECIFICATIN forming part of Letters Patent N0. 757,911, dated April 19, 1904.`

` Application filed December 2l, 1903. Serial No. 1864.026. (NQ modela) an improved article of the vcharacter mentioned that may be readily constructed and used and that will be eicient in'the cooling of drinking-water and in the preservation of articles of food and other things stored therein.

To these ends the invention consists of the refrigerator or cabinet and to combinations of parts and features thereof, as is hereinafter more fully set forth in connection with the accompanying drawing, forming a part of this specification, in which the figure of the drawing is a central vertical sectional view of my improved refrigerator.

Similar figures of reference designate similar parts or features, as the case may be, Wherever they occur.

In the drawing, 1 designates the walls or casing of the cabinet, which may be of any suitable construction and which. may be provided on top with a lid 2 or other opening means whereby access may be gained to the icereceiving chamber 3 of dish-like form, having a wall or partition 4 upon a supporting plate or shelf 4, in which the ice may rest. Below the partition 4 of the ice-chamber is another supplementary partition 6 of a form similar to the partition 4, and both partitions are supported by flanges 3 and 6', respectively resting upon ledges formed by the annular ring 7, secured to the inner sides of the wall 1 or in any other suitable way, the entire arrangement being such as to leave a space 8 between the partitions 5 and 6. Below the bottom 4, upon which the ice rests, is shown anthat either may be usedto support the cake of ice, the other being removed. If the cake should be thick, so that greater space should be needed between the ice-support and lid, the lower support or bottom 42 maybe used, or if a thinner cake should-be left in the ice-chamber in order to get at it readily=the upper shelf may. be employed. The two shelves are provided as amatter of mere convenience. For that matter one ice-support may be sufficient.

A hollow standard 9 is supported in the center of the cabinet, and a drain-pipe 10 is arranged in the standard and leads out through the partition of thecabinet, as is clearly shown.

The partition 5 has a stemilike opening 11 in its central lower part which lits in the top of the pipe 10, and the central lower part of the partition 6 is provided with a stem -like opening 12, which tits in the upper part of the standard 9;

A coil of pipe 13 is arranged between the two partitions 5 and 6 and at its upper end is provided with a funnel 14, arranged outside of the walls 1, into which drinking-water may be poured, and-at its lower end is a water-receiver 15, having a spigot 16, extending outside, through which the water may be drawn.

It will be understood that the ice and the water dripping therefrom and running down through the perforations 5 on the water-coil 13 will keep the drinking-water cool and that the waste water will run off through the pipe 10 and its escape attachment, cooling the hollow standard and through it assisting to cool the interior of the cabinet.

17 designates rings adapted to be slipped upon the hollow standard 9 and to be fixed in place thereon by set-screws 18, as shown. 19 designates collars adapted also to be slipped upon the hollow standard and to rest upon the fixed rings 17 and, if need be, turn thereon. The collars 19 have formed therein sockets 20, into which lit the angular inner ends .91 of the arms 22, which are recessed horizontally, as at 23, to receive the bails 24: of the ice-baskets 25, adapted to have placed in them lumps of ice to cool anything placed therein and to assist in cooling the interior of the cabinet.

The bails 24 of the ice-baskets may be slipped over the upwardly-projecting end 28 of the arm 22 and into the recess 23, said projection or other means of suitable character preventing the bails from accidentally slipping off the freev ends of the arms.

29 designates shelves, in the present instance shown as of segmental form, whichrat their meeting edges are offset in oppositedirections, as shown at 30, to preserve an even or smooth upper surface, said shelves being perforated, as at 31, and adapted to rest upon the arms 22. By the means describedthe cool air in the cabinet can circulate freely therethrough, and all of the parts may be readily removed for the purpose of cleaning or for other purposes.

By the construction described a refrigerator and culinary cabinet is provided which is very convenient in use, readily kept clean, and is so arranged that drinking-water may be supplied to and drawn from it with convenience also. When the ice in the ice-chamber is not sufficient to refrigerate to the desired degree, smaller pieces may be placed in the ice-baskets to cooll food placed on the shelves above or even in the ice-baskets.

By making the bottoms of concave form sheets for forming rests for the ice may be made of various sizes and on being placed therein will be brought nearer to or farther from the bottom of the ice-chamber, as will be readily understood. Besides all of the drip water will be guided to the hollow central standard to run down the same.

I claim- 1. A culinary cabinet or refrigerator embodying in its construction an ice chamber or receptacle having a partition of substantially concave form, a shelf supported thereby upon which the ice may rest, a supplementary partition, also of substantially concave form below the first-named partition of the ice-chamber, a central hollow standard with which the supplementary partition communicates, a pipe in the hollow standard with which the concave partition of the ice-chamber communicates, said pipe being provided with an offtake for the drip water, a coil of pipe between the said two partitions to receive drinking-water, means for filling the said pipe and for draining the water off therefrom. y

2. In a culinary refrigerating-cabinet, the combination, with the ice-chamber and its concaved ordish-shaped partition, and a shelf supported by the said partition, of a similarlyshaped supplementary partition below the partition of the ice-chamber, a coil of pipe between said partitions, means whereby water may be poured into said pipe and'allowing it to be cooled, and meansv extending outside of the cabinet for drawing off the cooled drinkingwater.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
