NEW YORK, N. Y., A CQRPORATION OF DELAWARE REFRIGERAIOI? CABINET CONSTRUCTION Application filed July 27,

My invention relates to the art of refrigeration and particularly to that phase of the.

1e suitably securing thereto a box-like metal liner having one open side. Suitable insulating material is placed around the five remaining sides of the liner and retained tightly in place by metallic hands. This assemm bly is then placed and suitably secured within an outer shell which is provided with a door for closing the open side of the liner. 'Due to the reduction in the amount of materials and labor required such a cabinet may be manufactured at a much lower cost than has heretofore been possible.

Furthermore my improved construction prevents condensation of moisture adjacent the liner. 89 cabinet is not tight against the liner and air can getin between the insulation and the liner, moisture precipitates due. to the low temperature prevailing. This condensation must be guarded against, particularly with mechanical refrigerator units, both to prevent water falling on the floor and to prevent rotting of insulation. ZBy impregnating and coating the insulation with a suitable Water proofing material of semi-viscous character and strapping the insulation tightly around the liner, I am able tofprevent air pockets next'to the liner and avoid condensation of moisture.

My invention is fully pointed out inthefollowing description taken in connection with the accompanying drawin s and further objects and advantages will e apparent therein.

Fig. 2 is a front elevati' cabinet shown in Fig. 1;

Fig. 3 is a cross-sectional view taken on the line 33 of Fig. 1;

Fig. 4 is a front elevational view of the interior assembly before being placed within the outer shell;

Fig 5 is a side elevational view of the assembly shown in Fig. 4;

Fig. 6 is a top elevational view of the assembly shown in Figs. 4 and 5;

Fig. 7 is a view, partially in cross-section of some of the members which constitute the interior assembly prior to being secured together. v

The interior assembly as shownin Figs. 4 through 7 will first be described. The assembly, in its preferred form, comprises two upright members 10 secured together by two horizontal. members 11 and 12. Members 10 and 11 and 12 are preferably of wood and constitute a frame which lies in a single vertical plane Member 11 is connected to members 10 at the top while member '12 is connected to them at a point some distance above the bottom. i

Securely attached to this frame by means of screws 13 is a liner 14. Liner 14 is box-- shaped and has closed sides, top, bottom and back but an open front. The interior of the liner itself is preferably lined with porcelain fused thereonto Around the five closed sides of the liner is placed a suitable heat nsulating material 15 such as cork board impregnated with water proofing fiuid material such as hydrolene. The cork board may be in one. single layer as is shown in Figs. 3 and 7 or two or more layers may be employed. In case a plurality of layers are used, the transverse oints in adjacent layers should be staggered so that there will be no joint extending all, the way through the in- -'sulation at any one place.

' On the outsideof the insulating material may be placed one or more layers of water proof paper (not shown). At the top, bottom and rear edges of insulation outside of the Water proof paper are placed protective 1 onal view of the angle pieces 16. These angle pieces do not necessarily extend the entire length oftheir respective edges. Two or more metal bands 17 are secured to horizontal member 11, pass across thetop of the insulatedliner, down the back and underneath the bottom and are secured to lower horizontal member 12. A similar set of bands 18 pass around the sides.

' and back of the insulated liner and have their frame. The pressure of the bands on the corner of the insulating material 15 is first applied to the protective angle pieces 16 which distribute the pressure evenly along the respective edges.

An aperture is provided in the bottom of liner 14 and adjacent insulation through which extends a short length of drain pipe 21. An aperture may be cut in the back of the cabinet for the passage of conduits for conducting refrigerant fluid to and from an evaporator.

Theparts and their relationship thus far described constitute the inner assembly which is placed within an outer shell 22; Shell 22 is preferably made of sheet metal suitably coated so as to resist' rust and corrosion. Wooden members 23 are bolted tothe bottom of the shell and serve to support the upright members 10 which are secured thereto by means of angle brackets 24. v

The front of shell 22 is formed so as to be in contact with two sides of members 10 and is secured thereto with the aid of a moulding 36.

Two or more brackets 25 are welded orotherwise secured to the inside of the back of shell 22 in such a position as to support the rear of the inner assembly.

The top and back of shell 22 are'removable so as to permit the inner assemblyto be put in place.

The'back is shown as being secured to the remainder" of the shell by screws 37 which engage screw threads formed in angles 38 which are fastened, as by Welding, to the side members of the shell.' A similar type of construction may be used to secure the top to the main part of shell 22.

The front of shell 22 is provided with a large upper opening and asmaller loweropening. The upper opening coincides with the open front of liner 14 and is normally closed by a door 26. Door 26 comprises arectangu- .lar frame 27, preferably of wood, to which issecured metal sheets 28 and 29. The space between sheets 28 and 29 is filled with insulating material 15. A moulding 30 is placed around the inner periphery of door 26 and serves to cover the edges of sheet 28. The edges of sheet 29 are bent around the sides of frame 27 as is clearly shown at 31. Door 26 is hung on a pair of hinges 32 and is held in its closed position by a latch 33. An additional strip of wood 36 is preferably placed adjacent to frame 27 on the right hand side of the door as viewed in Fig. .3 in order to give additional support for the hinges.

The space within liner 14 may be termed a food storage compartment wh1le the space in the lower part of shell 22 below the insulated liner may be aptly called the apparatus compartment. In the latter compartment is housed the apparatus comprising a mechanical refrigerating unit, with the exception of the evaporator which is placed in thefood storage compartment. Access may be had to the apparatus compartment by means of a removable panel 34 which is provided with louvres 35 to allow circulation of air in case the refrigerating apparatus is of the air cooled type. Openings (not shown) are also provided in the back of the apparatus compartment to aid in the air circulation.

The preferred form of procedure in assembling the cabinet, made possible by its Sim;- plified construction, is as follows:

The wood frame is first constructed by securing together members 10 and 11 and 12. Liner 14 is then fastened to this frame. Next the cork board 15, impregnated and coated with hydrolene, is put in place around the outside of the liner and covered with water proof paper. Bands 18, 19 and 20 are then placed around the now insulated liner and put under suflicient tension to hold insulation 15 and the water proof paper firmly in contact with the liner.

The inner assembly is now slipped into place within shell 22, the back and top of the latter not yet'having been placed thereon. Brackets 24 are secured to members 10 and 23 and the front of shell 22 is fastened to members 10 by mean-s of moulding 36. The

assembling of the refrigerator cabinet is now complete except forhanging door 26 and placing the back and top on shell 22.

The interior of the food storage compartment is provided with suitable supports for shelves which have'not been shown as shelf arrangements are old and well known;

While I have shown and described a more or less specific form of my invention, it is to be understood that modifications thereof fall within its scope. For instance,'the bands need not be all parallel or at right angles to each other but may pass around the insulated liner'in any desired directions so as to secure the best binding of the, insulation to the liner, though the arrangement shown is preferred. It will be understood that the invention is to be limited only by the appended claims considered in connection with the prior art.

What I claim is:
