10 Claims.

The fundamental objects of my invention are the provision of a method of assembly"and of a cabinet construction which is rugged, simple and inexpensive both to construct and to put together,

and which, after assembly, provides a neater and' better appearance, and a tighter and more perfect construction than it is possible to achieve other-- wise, excepting through the use of many more parts and a much more laborious method. The ancillary objects of my invention will be clear to one skilled in the art upon reading the ensuing specifications, wherein Ipshall describe an exemplary embodiment of my invention. Reference is made to the drawings, wherein:--

Figure 1 is partial perspective view of the outer parts of an exemplary cabinet. v

Fig. 8 is a detail section of a' portion of the cabinet at the side of the door opening, taken along the lines 8-8 in Fig. 4.

Briefly, in the practice of my invention I build up an outer structure comprising bottom, side Y and back members of the cabinet and appurtenances thereto. I fasten a wooden frame to this,

which is designed not only to receive an inner structure constituting the refrigerated or food compartment, but also to finish off the edges of the opening for the door and to serve in lieu of the parting strips heretofore used. The outer structure may next be lined with insulation, and the food compartment inserted therein. A special inter-fitting of the wooden frame with the inner and outer structures will be describedwhereby an attractive mum is secured without the use of additional parts. The cabinet is finished as will hereinafter be set forth. I shall describe my invention in connection with an exemplary cabinet of the type in which a compartment for the motor,

compressor and condenser is provided above the refrigerated compartn'ient which contains the evaporator; but it will be understood that my invention is not limited thereto.

In Figure 1, I have shown an outer assembly for a-refrigerator cabinet comprisingaflangedbote tom member I, to which the desired feet or other supports 2 may be attached, as by bolts 3, or otherwise. I provide outer side pieces for the cabinet indicated at 4 and 5. These side pieces have rounded edges where this is desired for appearance" sake, and may have flanges to the rear as indicated at 6 and I for co-operating with a back wall member 8, which may have co-operating flanges as shown. The front edges of the side 1 wall members are turned over as. at! and III to form side portions of the front of the cabinet. The width of this turned over portion will normally be at least-the thickness of the insulation which is used, as will hereinafter be explained. ,The extreme edges of the turned over portions 9 and It will be bent inwardly to form flanges l I and I2. p

A bottom piece l3 may be fastened in place, and this. piece may be flanged underneath, as at H in Fig. 5, to facilitate its connection to the bottom plate I. Its upper edge will likewise be turned over as at l5 to form a flange which is continuous with the flanges II and I2. A top front piece l6 may also be put into place. This front piece may be narrow or wide, as desired. In a type of cabinet where a motor and compressor compartment is located above the refrigerated compartment, the top front-member IE will preferably cover the front of the said motor compartment and may, if desired, be provided with louvres I! for ventilation. The top front piece It has side flanges 18 for juncture respectively to the flanges I I and I2 of the outer side members of the cabinet.

It likewise. has a bottom flange [9 turned inwardly and arranged so as to be continuous with the flanges II and I2 01' the side members, and theshaped strips of rubber 20, as most clearly shown in Figs. 1 and 6.

The upper ends of the outerside members t and 5. and the front top member l6 are of even height, and may have bent over flanged portions 2| and/or may be reinforced with an angular framework 22 (Fig. 5) so as to form a seat for the top member 23. of the refrigerator. The back member .8 in that type of refrigerator which a motor compartment above the refrigerated compartment, usually terminates short of the top of the device, as clearly shown in Fig. 5, so that the back of the motor compartment is open to the air.

Having thus constructed substantially completely an outer cabinet for the refrigerator, I

size as the door opening hereinabove referred to.

When the framework has been put into position the side members 24 and 25 lie behind the turned over portions 9 and Ill of the outer side members of the cabinet, as is most clearly shown in Fig. 'I.

The top and bottom members or rails 26 and 2! lie respectively behind the .top and bottom front members it and II. The frame of Fig. 2 is rabbeted, as at 28, so as to receive the rubber covered flanges Ii, l2, l5 and I! of the outer side and top and bottom front pieces of the cabinet. This relationship of parts is clearly shown in Figs. 6 and 8. When the wooden frame of Fig. 2 is placed in position, one legof the U-shaped rubber lining pieces may be displaced so as to permit the nailing of the flanges II, II, II and I! to the wooden frame by means of nails 29, as shown in Figs. 6 and 8. Other fastening devices may, of course, be used. Inwardly of the rabbets It the faces of the wooden frame may be beveled as at 30 in the several figures. This forms, as will hereinafter be made clear,.integral parting strips 30 for the refrigerator, and renders unnecessary the use of additional strips of material for this purpose. The exposed faces 30 of the wooden frame of Fig. 2 may be finished for decorative and/or preservative effect in any way desired.

The front face of the wooden frame member may be grooved as at ii to accept the inwardly extending joined flanges of the front side members 9 and ill, and the end flanges of the top and bottom front members l6 and I3, respectively.

40. I have shown in Fig. 3 a food compartment for the refrigerator, which is a unit. It either may be an integrally formed structure, or it may be a structure built up of a number of pieces of sheet metal. In any event, it is a box-like structure comprising a back wall 32, side walls 33 and 34, and top and bottom members 35 and 36, respectively. The side members may be provided with inwardly depressed ridges 31 to act as supports for the shelves where desired, and along the open side edges of the compartment there may be strengthening ribs 38. The food compartment is provided at its sides with forwardly extending flanges 89 and ill, and at its top and bottom edges with flanges ll and 42, both of which flanges are bent upwardly as shown; so as to lie at right angles respectively to the top and bottom walls of the structure. In that type of refrigerator in which the motor, compressor and condenser are located above a base, from whi h depends the evaporator structure, so that the whole mechanical assembly of the refrigerator can be removed as a unit, I provide in my food compartment member, as illustrated in Fig. 3, an opening ll through which the evaporator may be inserted. This opening may be surrounded by peripheral flanges if desired. It will be observed that the flange members 4| and 42 are adapted to lie face-wise against the wooden frame member of Fig. 2 and from the rear. The wooden frame member is grooved, as at 44 and II to accept the flanges SI and N of the foodfcompartment. Preferably these grooves extend the entire length of the wooden frame member, and

I lie outwardly of the innermostedges of the rab- -the outer exposed metal parts of my cabinet beted parts 30. shown in Fig. 8.

Inassembling my refrigerator cabinet. the next step will be to cover the bottom i of the outer shell with a suitable insulating material. The l kind of insulating material is unimportant so far as this invention is concerned. Conveniently it a may be in the form of a preformed block of insu lating material of the proper size, which can be slipped into place. The food compartment of '10 Fig. 3 can then be inserted into the structure, with the flanges l9, and ll lying in the grooves 44 and ll of the frame. Theflanges fl and 41 can then be attached to the upper and lower rails 26 and TI of the frame member, as by nails or U screws l6, whereby the food compartment may be tightly held to the wooden frame.

Next in the orderv of operations, I place inaulation about the sides of the food compartment. i. e., between the food compartment proper and a the side members 4 and I, and the back member 8 of the outer shell of the refrigerator cabinet. Next I insulate the top of the foodcompartment.

This construction is clearly .Where an opening 43 has been left for the insertion of the evaporator, this space will, "of course, not be covered by insulation. Next place in position a member 41, shown in which forms the floor of the motor and compressor compartment. This member mayhave' at its rear edge a turned over portion 4! to 9 engage the upper edge of the outer back wall I member 8. Its forward edge 40 may overlie the upper rail 26 of the wooden frame member, and may be attached thereto in any way. desired. The motor 50 and the compressor ll, together 35 with the evaporator (not shown), and such other associated apparatus as may be required, may be mounted upon a base 82, from which the evaporator II is suspended. The member 61 will, of course, have an opening therein registering with 40 the opening 43 of the food compartment ofFig. 3 to receive the evaporator. The assembly of motor, compressonevaporator and the like is not a limitation upon my invention, and has not been illustrated in detail. I have shown in several of 45 the figures shelf members .34 lying on the. shelve supports 31. a

In finishing the refrigerator cabinet, it will-be usual to hinge a door to the front side member II by'means of hinges I5. and to provide the 50 door It andthe front side member 0 with cooperating parts of a latching mechanism. -The other details of construction, such as the type of door, the anti-rattlingstripping which is commonly used between the top a and the top edges 5 of the refrigerator cabinet proper, and other details, are not limitations upon my invention, and have not been illustrated herein, nor specifically described.

In the manufacture of cabinets in accordance with my invention, the food compartment may have been previously finished, as by enameling in any way desired. It goes without saying, that may be finished as by enameling prior to assembling;. but where this is not desired, it will be found practicable to make the assembly hereinabove described, and then send the entire cabinet through spraying rooms,,or the like, for the 70 finishing at least of the outer parts of the cabinet with coatings of sprayed substances.

Modifications may, of course, be' made in my invention without departing from the spirit thereof. u
