This application 'is a division o applica tion Serial No. 498,979, tiled by me in the United States Patent Oliice May 28, 1909. Referring more particularly to the drawings and 1n the present exemplilication of the invention, the numeral 15 designates generally a casing which may be constructed of any desired material and may lbe of any desired size and configuration. In the preeent cxempliication of thisJ invention, how-` ever, the casing is preferably rectangular in oonfiguiatiomoomprising front, back and sido walls. The casing is provided with an i inner wall and each of the sections of this wall is constructed of a .body `portion 1f` shown more clearly in Fig. 2 to which is secured strips 17. The body portion 16 of the `back and side Wallsoff the refrigerator propo:` is of a size to eistend throughout the entire height of the Ycasing and each of `the walls is constructed as a single unit.

Alfter fthe strips 17 have been secuned to one face of the bod portion, a suitable heat insulating material7 18 is placed upon the body portion between the strips 17, and the space between the strips and above tbe heat insulating material 18 is filled with suitable beat non-conducting material 19, such as mineral wool, asbestos and the like, and the spaces are filled substantially flush 'with the exposed faces of 'the strips. A sheet of asbestos or other suitable heat mon-conducting materialQO is then placed across the strips and the packing and :secured in any desired or suitable manner. The top and bottom of the compartment is constructed :in the same manner. After the walls and bottom have been thus cfimstructed, the bot-- tom is first pla/ced within the outer easing so as to rest upon the bottom thereof Wirth Y the insulating material 20 in engagement with the bottom off the Iouter casing, ,anteiwhich the sides and back wall of olie comartment are placed in position `and ad- )usted against the walls off the outer casing v length. The

66 /to the edge uponwhich theA flange 24 isar- E with the insulating material 20 in engagement therewith. rlthese walls may then be secured in position in any desired or suitable manner not necessary to illustrate but in a manner to permit the walls to be readily removed when desired, and at the same time hold them in position when adjusted. The top of the inner casing may then be placed in position so as to be supported by the sides and back walls.

rlhe casing is divided by an upright partition into two compartments to form an ice bunker `designated generally by the reference numeral 21, and a food compartment designated generally by the reference numeral 22 in Fig. 2. The partition between the ice bunker and the food compartment is of a knock-down construction and is preferably constructed of metal comprising two or more uprights 23,the body portions of which are preferably of channel formation, as shown more clearly in Figs. 3 and 6, and projecting laterally beyond the free edge of one of the sides of thechannel is a flange 24 whichis provided with a series of keyhole slots 25 at intervals throughout its flange 24 is arranged adjacent of the channel and is adapted to rest against one of the inner walls o the compartment. One of these uprights is referably arranged adjacent the rear an one adjacent the front wall ofthe compartment; `The supportadjacent the front wall of the refrigerator compartment is prelerably arranged adjacentthc stile 26 (see Fig. l) between the doors 27, 28 and 29, which open through the front wall of the refrigerator and through which access may be had rethe open edge spectively Vto the food compartment, the -ice bunker Aand the portion of the food compartment below the ice bunker.l The walls to which these uprights are secured are rovided with pins or projecting'lugs 30 w ich are provided with heads ,of a size topass through the openings 25 so that the uprights ma belowered to cause the shanlrs of the pins or projections to enter the smaller portions of the slots to support and secure the uprights in position so` that the body portion of the'uprig'htwill be held spaced from the wall' by means of the sides of the channel. These uprights are provided with slots-31 which pass through one edge thereof, preferably the edge opposite downwardly.

ranged, and incline provided 'number of these slots 31 may be throughout ,the length of the uprights 23.

'A series of members or partitions 32 are provided and each is preferably constructed of a vstrip of sheet material of'a thickness substantially equal to the width of the slots 31 and of a height substantially equal to the length of the slots.

One edge of the members 32 is deflected to form a' depending flange 33 along one edge. The other edge of the members 32 is rolled as at 34 to form a reinforce for the edge and this rolled portion terminates short of the extremities of the members 32 as at 35 a distance equal to the width of the sides of the body portion 23 of the upright. The extremities of these members or partitions 32 are inserted in the respective slots 31 in the uprights 23 with the rolled portions 34 preferably located adjacent the lower extremities of the slots and with the deflected portions 33 adjacent the outer edges of the slots. When these members or sections 32 are arranged in position and supported by the uprights,` they will form ports or passages which extend downwardly from the ice bunker 21 into the food compartment 22. By constructing the partition in this manner it will be apparent that the partition may be knocked down or separated for the purpose of cleaning the same. ln order to prevent accidental displacement of these members or partitions 32 during transportation, a suitable lock may be provided. A simple and efficient means for accomplishing this purpose comprises a member 36 (see Figs. 2 and 9) which is preferably constructed of a strip of metal having a curved or bent end 37, which is adapted to engage over the top edge of one of the sides 38 of the upright 23. This y member 36 is of any suitable length but is of a length substantially equal to the length of the side 38 of the upright so that the body plortion of the member 36 will extend over t e edge of the partitions or members 32 .adjacent the open portions of the slots 31. The member 36 may be provided with a `slot 40 adapted to receive a fastening device 41, such as a turn button or the like, which is supported by the side 38 of the upright and when this member 36 is thus locked in position, it will be apparent that the partitions or members 32 will be held against displacement. One of these members 36 ispreferably provided foreach of the uprights 23. By constructing the upparent that the extremities of the members bor 4partitions 32 will enter the slots 31 .a

suicient distance to project `beyond the sides thereof to form an adequate support for the members or partitions. The other side 42 of the uprights is cut out portions 43 are deflected to form laterally `projecting portions extending beyond the side. 4Secured to the opposite Wall of the food. compartment and adjacent the corners thereof, are uprights 44 which are also provided' with cut out portions deiected as at 45 to form lateral projections cop er ating with the projections 43, land ythese coperating projections 43, 45, .form

supports for the shelves 46 in the food com-l partment. The members 44are also proi right 23 of channel formation, it will be apcut out and the vided with lreyhole slots 47 adapted to oooperate with suitable pins or projections 48 on the wall of the compartment in a manner similar to that in which the slots in the uprights 23 cooperate with the pins or projections for removably and securely holding them in osition.

Arranged elow the partition formed by the uprights 23 and the members 32 is a partition 49 (see Figs 2 and 5). This partition is preferably constructed of sheet material and the opposite edges 50 thereof are deflected to form lateral projecting portions and each of-these deflected portions 50 is provided with bayonet slots 51 opening through the edges thereof, which coperate with pins or projections 52 on opposite walls ofthe compartment. This partition 49 is of a length to extend across the refrigerator compartment so that the deflected portions 50 thereof will rest against the opposite 'walls and when secured in position by the bayonet slots 51 and pins or projections 52 the artition 49 will substantially form a continuation or depending portion of the partition formed by the uprights 23 and the members 32. This section 49 of the par-v tition preferably terminates some distance above the bottom of the compartment to form an air circulation passage 53 and the bodyportion of the partition is cut-out and the cut-out portions are deflected as at 54 to form shelf supports similar to the sup- I ports 43, 45. A support 55, similar to the support 44 is provi ed with laterally deflected portions 56 and is secured to the wall of the refrigerator compartment on the opposite side of the partition 49 so that shelves 57 may be supported on each side of the partition 49, the shelves 57 on one side of the partition extending below the ice bunker 21.

Supported in any desired or suitable manner, preferably by means of angle irons 58 adjacent the base of the uprights 23 is a pan 59, shown more clearly in Figs. 2 and 7, which is provided with elongated apertures (30 in its bottom. This pan serves to form the bottom of the ice bunker 2l and an ice supporting rack 61 having end members 62 is supported in any desired or suitable manner, either by means of the ends of the members 62 nesting upon the edges of the pan 59 or by means of suitable anglo irons 63 provided for the purpose. The extremities of the end members G2 project for some distance beyond the sides of the body 61 to form air circulation openings 64. The bottom of the pan preferably inclines down- Wardly and toward the rear, as shown more clearly in F ig.,4, and arranged around the apertures 60 are Iianges 65. The pan receivesthe drip water from the ice G6 and the flanges 65 prevent the water fromvpassing through the apertures 60. The pan is 65 provided with a discharge outlet opening 67 at the rear thereof, around which open ing is arranged a flange 68 adapted to telescope into the upper extremity of un over How pipe 69, which is supported in any desired or suitable manner. The lower extremity 7() of the overflow pipe telescopes with the upper extremity 71, of a pipe 7 2 which leads to the sewer or any other point of discharge.

lilith' this improved construction of refrigerator compartment, the air currents will pass from the ice bunker downwardly into the portions of the food com artmexit below the ice bunker to be discharged through the opening 58 to the other side of thepartition 49 and will rise in the portion of the .food compartment on'the other side of the partition toward the top of the compartment. During this rising movement, the air currents will pass into the ports or passages formed by the members or partitions 32 vand will be drawn therethrough into the ice bunkerwhere they will contact with the ice, causing the ltemperature of the air currents to be lowered. As the temperature is lowered the air will continue to circulate from the ice bunker and through the food compartments.

The door 27 in the outer casing 15 is ar-v ranged so as to close the food compartment on one side of the ice bunker and the artition 49, through which access .may be ad to that portion of the food compartment. The door 29 is arranged to close the portion of the food compartment below the ice bunker and the door 28 is arranged to close the opening in the casing through which access may e had to the ice bunker so that ice maybe supplied to the ice bunker without opening the closures 27 and 29.

lVith this improved construction of refrigerator it will be apparent that the entire inside of the refrigerator may be removed including the inner walls and partitions and the partitions or Inembers 32 which form the air passages from the food compartment to the ice bunker may be removed and thoroughly cleaned and after being cleaned may as readily be replaced.

Obviously the shelves 4G and 57 may be provided with apertures or openings 73 therethrough so as not to im ede the circulation of air through the foo compartment..
