^ .My .invention consists of a novel construction of a vrefrigerator wherein l i provide means; forv supporting the ice or cooling medium directlyupon a coil having a connection' with the-citymain or other constant water supply', provisionbeing made by a novel construction and collocation of shelves, which terminateat a suitable distance from the front andxsides of' the refrigerator for enablingal plurality of compartments to be foimec'l,-wliich are in free communication notl only with each other but also with the ice chamber, so that thev cooling effect of the ice is felt in a substantially equal. degree 'throughout the entire interior of the refrigerator and the plurality of chambersformed therein, so that the cooling effect of the ice is-utilized to a maximum extent. .i

"To the aboveends,'myv invention consists of'a novel construction of refrigerator having a plurality of superposed compartments, which are in free communication with each other and with the ice chamben` so that provision is made for the cool air to be present or to circulate in every portion of the refrigerator.

lt further consists of a novel construction cfa drip 'for the interior of the refrigerator provided at its bottom with a water: seal, whereby the ingress of warm air to the refrigerator is prevented.

lt further consists of other novel features of constructiomall as will be hereinafter fully set forth.

For the purpose of illustrating my invention, l have shown in the accompanying drawings, certain forms thereof which are at present preferred by me, since the same will gite in practice satisfactory and reliable results, although it is to be understood that the various instrumentalities in which my invention consists may be variously arranged and organized and that` my invention is not limited to the precise arrangement and oi'- ganization of these instrumentalities as herein shown and described. l

Figure l represents a front elevation of a refrigerator embodying my invention,.the door thereof being shown open.

Figure 5 represents a section on line 5-5 Figure 4. Y

figure 6 represents on anv enlarged scale a sectional view of the lower portionpof the refrigerator corresponding to the lower lefthand portion of Figure Il.

Similar numerals of referencev indicate corresponding parts.

Referring to the drawings designates my novel constructionl of re- "ri `fer-atei, the same comprising an outer cas i f 2 of wood or other' material, an inner of enamel, Zinc or the like 3, and an ntermediate filler of non-conducting mai' et, such charcoal or the like. The erator front 5 is provided with a door opening` 6 located'at one side of said front, which is closed by the door 7. The top 8 is provided with a lid or closure 9 which is in vertical alignment with the ice supporting shelf it). which latter also supports the coils ll, which have the inlet branch l2 leadingl thereto from a running water supply, such as a city main, the outlet from said coils ll being indicated at 13, and leading to the spigot il, whereby upon opening` said spigot, a fresh supply of cooled running water is always available, by reason ofthe ice l5 being'supported directly upon said coils ll.

The drip from the melted ice is conveyed through the pipe i6 to a point below the refri erator bottom 17 and saiddrip pipe has attached thereto theelbow or U-shaped fitting 18, which ensures a water seal at all times, so that no warm air can enter the refrigerator upwardly through said pipe 16. A pan i5 is located below the water seal 1S for catching any over-How therefrom.

' upper shelf i9. which is preferably ss, is supported by the angles 2O or tleir equivalents and the rod 2l. rlhe lower sl f l s supported by the angles 23 and thV edge of the ice su'iporting shelf l0.

e it will be seen in my invention that the front edges 243 and Qi' of the shelves 19 and 22 terminate a short distance from the front refrigerator, see figures 3 and 5, so as to form a ontinuous opening or passageway from the bottom chamber tl lOO lli)

intermediate chamber 29 and the upper chamber 30, and the side edges 31 and of said shelves 19 and 22 terminate in proximity to the ice chamber, as seen in figure 4, so that the effect of the ice or cooling medium 15 is present throughout the en tire interior of the refrigerator and is substantially equally present inthe three chambers 30, 29 and 28, and there is consequently vby Vmy construction afforded a free circulation of the cool air throughout the three Vchambers 28, 29 and 30, in which the edibles .or other articles to be cooled are placed.

The closure 9 not only permits the insertion ofthe ice, 1but also gives access to the upper shelf 19, and the upperI chamber 80, while the opening of the door 7 permits access to the chambers 29 and 28.

preferably make the shelves 19 `and 22 of glass or similar material and the saine can be readily removed and cleaned, as is evident, according to requirements.

It will be'apparent from the foregoing` that all the articles contained in the refrigerator Vare subjected `to the kmaximum cool ing effect of the cooling medium, and that my device ,possesses advantages over the usuall type of refrigerator commonly in vogue, wherein the ice is contained in a separate chamber, whose walls do not permitthe cooled air to contact directly with the ,articles to be Cooled to the vsame extent as my device does. v The 'door and the lid are provided with packing to make air tight joints with the parts of the casing with which they contact.

- .I-Iavingthus described my invention, whatl 'claim as new and desire to secure by Letters Patent, is

1. In a refrigerator, a casing having a side o eninof at its to for the insertion of ice and `an Vopening and front door at one side ofV "its front, -a -side ice chamber located at about the middle of said casing at one side thereofand under said top opening and hav- `ing a bottom shelf, upper and intermediate aligning cooling chambers located at the side of said casing opposite to said ice chamber and in free communication there with, shelves 19 and 22 forming the bottoms of said upper and intermediate cham- :bei=s,the1inner side edges 31 and 32 of said shelves terminating in proximity to said ice chamber, while their front edges 26 and 27 terminate a short distance from `the refrigerator front .so @that said upper and intermediate chambers communicate with each other and withv said ice chamber, and a lower Icooling` `chamber below said ice chamber and shelf 22 and extending across the enti-re lower portion of said casing and in -free communication with said upper and intermediate cooling chambers and with said ice chamber.

2. In a refrigerator, -a :casing having .an opening at its top at one side thereof for the insertion of rice, and an opening and side door at :one side of ,its front, an intermediate lside ice vchamber in .alignment with said itop opening, -an intermediate sidecooling chamber .laterallyjuxtaposed in sub` stantiallly `horizontal*alignment .to nsaid ice chamber and in free communication therewith, an upper side cooling chamber, aa bottom Vcooling chamber extending l.under said ice chamber and the width of :said casing, shelves for ,said upper .and intermediate chambers7 the front Aedges 26 and 27 .of .said shelves `terminating `at short distance from the front .of said refrigerator, so that said upper and .intermediate chambers freely communicate, :and the sideedges 31 and 32 of -said `shelves terminating at about the middle of vsaid .casing .in proximity to said ice .cham-ber, so that the latter is `in free communication with said lower, intermediate and upper cooling chambers, and a coil in said ice chamber upon which the ice is supported, one Iend of said coil being adapted to be connected to a city main, and .the Vdischarge end .of sai-d coil being connected to La. spigot supported in the refrigerant-or wall.
