The present invention contemplates many new and improved features for insulated refrigerator cabinets which tend toward simplified and economical production of, and toward more eflicient cabinets of this character, and also includes improved methods of construction and assembly of the various parts of the cabinet.

Referring to the accompanying drawings in which like numerals refer to like parts throughout the several views, the refrigerator cabinet illustrated is of the character used in connection with mechanical refrigeration, but it is to be understood that many of the improved features of the present invention are applicable to cabinets employing other refrigerating mediums or means.

In general, the refrigerating cabinet illustrated in the drawings includes an outer casing A of metal, an inner casing B of metal which forms the lining for the refrigerating chamber and insulating material between these casings. These parts are so arranged that an opening is provided near the upper rear portion of the cabinet for the reception of a mechanical refrigerating device, the cooling element, coils, motor, compressor, and associated parts being so arranged that they can be assembled at the location of such opening as a unitary structure, while providing an efficient seal with theinner casing so that the cooling element only extends into the refrigerating chamber. The present invention also includes an efflcient rigid means for mounting and supporting the refrigerating unit in a cushioned manner at the above location of the cabinet.

The casing A is of one piece metal construction and the metal at the. forward edge of the top, bottom and sides thereof is flanged toward the casing B to a width substantially the same as, or to a desired degree greater than the spacing between the two casings, as-indicated in Figs. 2 and 3 to provide the front face I of the cabinet, and the inner marginal edges of the front face I are turned inwardly substantially parallel to the top, bottom and sides to provide a continuous flange 3 extending toward the rear of the cabinet,

which flange defines the door opening 2.

The front portion of the outer casing A carries an open, rectangular frame 4, preferably of wood, which at its forward face abuts the front face I and at its inner periphery abuts the continuous flange 3, the continuous flange 3 serving as a locating means for this frame. The rearward edges of the top, bottom and sides of the outer casing A are also flanged toward the casing B to provide a substantially continuous flange 5 which defines the opening 6 at the rear of the outer casing A and which as will be later described holds the rear panel in position.

The overall dimensions of the frame 4 are slightly less than the corresponding dimensions of the rear opening 6 so that the frame 4 may be inserted as a unit through the opening 6.

The inner casing B having the general shape illustrated in perspective in Fig. 13, is positioned within the casing A in peripherally spaced relation and is preferably provided at its forward edge with a continuous inwardly offset flange I 3 which abuts against the inner peripheral faces of the frame 4 and which is secured to such faces by any suitable means such as the screws 8. The edge of this continuous flange, however, is spaced from the edge of the continuousflange 3 at the front face I of the outer casing A, and the inner faces of the frame 4 are provided with grooves 9 therein'that are continuous with each other and underlie the space between flanges 3 and I. In order to conceal the edges of the flanges 3 and 'I and to conceal the screws 3 which secure the flange 1 tothe frame 4, a flexible molding or gasket ID of any desired material is employed. This gasket which is more clearly shown in Fig. 8, is formed with opposed narrow recesses extending throughout the length thereedges of the flanges 3 and I and into the grooves 9, is formed witha V-shaped longitudinal recess so that this portion can be compressed to permit insertion into the grooves 9 and has sufflcient resiliency when inserted that it securely grips the flanges 3 and l to exclude moisture from the space between the inner and outer casings.

In order to strengthen the bottom of the casing A it is preferred to employ a reinforcing plate H, which is merely positioned upon the bottom, or which, if desired, may be welded or otherwise secured thereto.

The inner casing B extends rearwardly within the outer casing A and terminates short of the rear face of the casing A to provide a rear insulation space. Near the upper end of the in-, ner casing. B the sides thereof are cut back as indicated in Figs. 1 and 13, and the top of the casing B extends to the region of the edge of the cut back portions of the sides. The marginal edges of the side portions at this cut back region are flanged inwardly at l2 and are flanged rearwardly parallel to the sides as indicated in Fig.

2 to provide inwardly oifset flanges l3 for a purpose to be later described.

Suitable insulation material l4 in block or other suitable form is disposed between the bottoms of the inner and outer casings, as indicated in Fig. 3, and this insulation abuts the frame 4 and extends rearwardly beyond the rear portion of the inner casing B nearly to the flange 5 of the outer casing A, but spaced therefrom. Similarly, insulation material I 5 is disposed in the space between the sides of the. inner and outer casings as indicated in Fig. 2, and insulation material It is disposed in the space between the tops of the casings A and B. The insulation material I6 extends slightly beyond the rear edge of the top of the casing B as indicated in Fig. 3, to the same extent as the side insulation l5 adjacent the cut back portions.

The rear of the inner casing B is closed in by means of a back I! which is formed with a reversely curved portion "a at its upper edge which fits over the cut back portions of the side and is welded thereto. The back I! is also formed with a rearwardly extending flange 48 which is' adjacent the flanges I3 of the sides and which has its ends securely welded thereto.

It will be noted that the flange 18 of the back l1 is disposed some distance below the edge of the top of the shell B to provide the space or opening IS in the back of the inner casing B for the reception of a mechanical refrigerating unit which will be later described.

The region surrounding this opening I! is reinforced by an open rectangular frame 2| which abuts against the flanged portions l2 of the side portions of the casing B and against the curved portion lla of the back l1, and is confined within the flanges I3 and I8 and a flange 23 of an angular member 22 which is welded at its upper edge to the rear edge of the top of the inner casing B and which is welded at its ends to the flanges l3.

The frame 2| is held in place by means of screws25 which extend through'the flanges I 3, l8 and 23. Interposed, however, between the flanges I3, l3 and 23 and'the inner periphery of the frame 2|, is a continuous molding or seal-. ing gasket 24 of a. hollow construction, the hollow portion of which extends inwardly beyond these flanges into the space l9. This gasket 24,

. as more clearly shown in Figs. 6 and '7, comprises the rectangular portion which is secured to the framework and a flexible arched portion 24a joined at its ends with the rectangular portion and which has a recess 24b that receives and conceals the edges of the flanges l3, l3 and 22. The arched portion 24a also has a central longitudinally extending rib 340. It will *be noted thatthe arched portion 24a projects well beyond the flanges l3, I3 and 22, so that when the refrigerating unit is in place as indicated in Fig. '1, this portion will flex inwardly to provide a continuous 3-point longitudinal contact with the separator block 53 of the refrigerating unit. When the portion 24a is distorted in this manner it provides a perfect seal and yet does not exert such a binding effect on the block 53 as to prevent dimcult removal of the block. Positioned rearwardly of the back I1 is a body of insulation material 26, the rear face of which is substantially in alignment with the rear faces of the insulation material l4 and I5. The insulation material 26 extends upwardly to the same height as the vertical portion of the back l1, and a block of insulation material 28 is disposed to seat on the curved portion |1a of the back l1 and the upper end of the insulation material The insulation material l5 between the sides of the inner and outer casings A and B is shaped to correspond substantially to the sides of the inner casing, and the portions of thisinsulation material, as before stated, at the upper end of casing B extend slightly beyond the flanges l3 and the horizontal flange 25. The frame 2| is rabbeted at 30 at its outer rear corner through-- out the sides and top thereof to provide a recess and the insulation material l5 and I6 extends substantially to the edge of this recess, as shown in Figs. 2 and 3. In order to locate the insulation material l5 and I6 adjacent the frame 2|, retaining panels 3| of Celotex or other suitable loosely pressed material, are disposed between the framework 2| and the sides and top of the outer casing, these elements being disposed in the recesses in the frame 2| and being secured to the frame 2| by means-of suitable screws or nails 32.

Interposed between the insulation material 26 at the rear of the lining back I1 and the inwardly turned flange 5 of the outer casing isa back panel 33 of a suitable material, such as Celotex, which is provided with a metal facing 34. This panel 33 extends from the bottom of the outer casing A rearwardly of the lower insulation material |4 substantially up to the height of .the

horizontal insulation material 28 as indicated in Fig. 3, and is held in place by means of screws 35 extending through the continuous flange 5 and into the panel 33.

Extending horizontally over the insulation material 28 is sealing panel 36 of Celotex or other suitable material, which panel 38 is provided with a facing 31 of metal. This panel also seats upon the upper horizontal edge of the back panel 33 and extends from the flanges 5 of the sides of the outer casing over to the edge of the horizontal portion of the wooden frame 2| slightly above the edge of the frame.

As more clearly shown in Figs. 6 and 14, the

facing 34 which extends over the end of the back- 3 panel 33 is doubledback upon itself and then flanged to form .a continuation of the surface facing 34 to provide a flange 34a. After the sealat this location through the medium of a number of spaced guides 33 of suitable channel shape which are secured by means of screws 39 extending through the flange 34a, the horizontal panel 33 and into the back panel 33 at the rear side, andgby screws 43 at the forward ends extending into the horizontal portion of the frame 2|, a suitable spacing strip 4| being interposed between the guides and the gasket 24.

In order to prevent the formation ofadmission of moisture to the insulation material, a plastic material 23 preferably having an asphaltic content such as Hydrolene is interposed between the back insulation 26 and lining back H at the one side and the back panel 33 at the other side, and also between the horizontal insulation 23 and curved portion |1a of the back, the lower portion of the frame 2|, and the sealing panels 23 and 33 as indicated in Fig. 3. Such sealing material 29 may also be disposed between the frame 2| and portion |1a of the lining back, and between l5 and I5.

Extending from the back panel 33 upwardly and then horizontally within the outer casing l are strap members 42 which are secured by means of screws 43 to the back panel and by means of screws 44 to the upper horizontal portion of the frame 2|. These straps form the support for a shield or housing 45 which substantially closes in theback of the opening l9, leaving a space 46 opening downwardlyand spaces 41 opening horizontally outwardly at the ends of the shield 45 for the circulation of air to the mechanical refrigerating unit.

Additional panels 48 of Celotex or other suitable material abut against the sides of the outer casin'gand extend between the panels 3| and flange 5 from the horizontal panel 38 upwardly to the top of the outer casing. p

The straps 42 also support a horizontal panel 43 which extends between the panels 48, and'between the flanges 5 of the sides of the outer casin and the edge of the upper portion of the frame 2|, this panel being held in place by a flange 50 formed on the-housing 45 and clips 5| carried by the screws which secure the straps to the frame'2l. H

The refrigerating unit is assembled as a unitary structure and comprises the cooling element 52 which is secured to one side of a vertical mounting block 53 and the condensing coils 53a, and motor and compressor unit 5311 which are carried on the opposite side of the mounting ,block 53, and this unit is so arranged that it can be inserted through the door opening 2 of the cabinet into the cabinet and positioned upon the guides 38, openings 33a being in the guides 33 for the reception of bolts to additionally hold the refrigerating unit against end play. The mounting block 53, when in position, is confined within the endless hollow gasket 24, this molding being compressible when the block is inserted so as to form an airtight seal with the block. An additional seal is also provided by forming the mounting block- 53 with an additional endless gasket 54 which engages with the entire periphery of the unit opening |9 deflned by the flanges I3, l3 and 22, this gasket being so arranged that when the refrigerating unit is secured in place by means of nuts 55 threaded'on screws 56 carried by the frame 2|, it will be pressed between these flanges and the sealing plate 51 carried by the block 53 to further provide an'fairtight seal.

In order to avoid metal to metal contact with the inner casing B and to also cushion the refrigerating unit, the ends of the angle elements 56a which contact with the casing B above and below the opening I8, and the refrigerating unit are enclosed within rubber insulators 58b.

The door 58 is mountedon hinges 58 and is formed from an outer panel 88 of metal and an inner panel 8| of metal. The outer panel is formed with a continuous flange 82 at its periphery, which flange is inturned to provide a continuous inwardly extending ledge 83. outer panel 88 is reinforced with an endless frame 64 preferablyof. wood, which seats against the panel in spaced relation with respect to the continuous flange 82, and this frame 84 is held in place by means of clamping straps 85 which are disposed intransversely extending recesses 68 arranged at intervals around the. periphery of the frame 64. Each of these straps 65 is formed with a flange 81 at one end which is secured by means of a screw 88 to the frame 64 and at the other end with a reversely curved portion 68 disposed to seat against the ledge 88. This strap is of such a length and is so disposed that when the screw 68 is screwed into the frame 64 a fulcruming action is produced which causes the reversely curved portion 68 to securely abut the ledge 63 and thereby force the frame 84 firmly against the outer panel 88. Positioned within the inner periphery of the endless frame 64 is a body of suitable insulation material Ill and extending across this material and across the frame 64 is another body II of suitable insulation material. The inner panel 8| of the door is dished and provided with a peripheral flange I2 which surrounds the insulation material II and the wooden frame 64 andwhich is secured to the frame 64 through the medium of screws I3. The margin of the continuous flange 12 is turned outwardly to provide a continuous flange H the edge of which flange is spaced inwardly from the ledge 63 but substantially in the same plane as theledge 63. The spacing between the flange I4 and the ledge 63 provides an opening for the reception of a flexible door gasket 15. This gasket 15 is tubular and provided with a projecting portion at one side, which portion is recessed to receive the edges of the continuous flange I4 and ledge 63 when the projection gasket is inserted within the opening between the flange 14 and ledge 63. The gasket furthermore is provided with a series of corrugations or teeth I8 which, when the door is closed, engage withthe portion of the outer shell of the casing which defines the door opening. When the door is closed the tubular gasket is distortedsomewhat and these corrugations 16 exert a gripping effect against the door frame and insure a perfect seal.

The bottom portion of the outer shell is provided with downwardly extending lugs 88 which are arranged toextend into recesses formed in a suitable supporting base ll for the cabinet structure.

Secured to the sides of the inner casing B to project inside the same are a number of buttonlike elements I88 for supporting shelves (not shown) within the refrigerating chamber.

While the cabinet described is adapted for use with a mechanical refrigeration unit, it is to be understood that the present invention may be carried out in substantially the same manner to provide an ice receiving cabinet, in which case, the opening I9 can be omitted and the lining back I'I, insulation ZG'and back panel extend to the top of the cabinet. A suitable shelf or parti- The.

tion may then be provided for supporting a cake of ice.

It is preferred to form the outer casing A from a single blank of metal, which in the preferred form has the approximate shape, illustrated in Fig. 10, having portions C and D representing the top and side portions, and bottom portions E at the ends. The edges of the blank at the dividing lines indicated in dotted outline by the numeral 'II are notched out at I8 to provide the rear flanges 5 and at the opposite edge to provide the flanges I which form the front face 'of the cabinet. Prior to the bending operation the sheet is stamped, either after the formation of the notches I8 or simultaneously therewith to form the flanges 5 and to form the front face flanges I, and subsequently the marginal flanges 3' are formed at the edge of the flanges I. Then the blank in such formed condition is shaped by bending on the bending lines I1 to form the same to flnal shape. The transverse edges of the two bottom portions E of the blank are welded together throughout their width and the ends of each flange provided by the notched out portions .18 are welded to the end of the next adjacent flange and similarly the ends of the flanges I are in contact when the blank is formed to shape and are welded together at Ia as indicated in Fig. 11. The ends of the inturned flanges 3 are also welded together to form the continuous flange around the door opening. After the blank is formed to shape and'the welding operation performed the formed blank is vitrifled or finished by painting alone or in any other suitable manner. It will be noted that the welding Ib which unites the transverse ends of the blank occurs intermediate the ends of the bottom portion of the casing, but it is to be understood that this may take place at any other location such as at one of the corners of the casing.

The outer shell may also be made of one sheet of metal by flrst notching at I8, next forming at lines 11, and then welding the ends together. After this the shell may be dropped over a metal box-like core of collapsible form and struck with a die which forms and flanges the entire front face I and 3 in a single operation. The rear flange is then formed over the core, after which the core is collapsed and the shell removed and the meeting edges of the front face thereof welded.

The inner casing, which forms the lining for the refrigerator is preferably made from four blanks of metal, namely, a rectangular blank 18 forming the top, a rectangular blank 88 forming the bottom, a blank forming the flange 23, and a blank 8I forming the sides and back of the casing B. If desired, however, the casing B may be formed from a one piece blank. The blank 8| is notched out at 82 ,to provide for the opening inthe back of the lining for the mechanical refrigerating unit, and it will be noted that the 83 is stamped to a curve shape starting at dotted line 84 and is reversely bent at the dotted line 85 to form the rearwardly extending flange I8 that defines the bottom ofthe opening I8 for the refrigerating unit. The inwardly extending projections formed at the edges of the side portions G are shaped by bending the same at right angles to the side portions and then by reversely bending the same along the dotted lines 86 to provide the flanges l3 which define the sides of the opening I8 for the refrigerating unit. The two side,

portions G are then formed by bending the blank along the dotted lines 81 and in this position the;

lateral edges of the projecting portion 83 rest against theedges of the notched-out portions of the side portions Gy and the endedges of the flange |8 rest against the bottom edges of the tom edges of the back and side portions F and G,

respectively. The welding of these various edge portions together is indicated at 89 in Fig. 13.

Although the inner shell is shown and described as being made of four pieces, it may be desired to form the same of three pieces by forming the flanges 22and 23 as an integral part of the top blank 19, which eliminates the necessity of providing the long weld between the edges of the top blank I and flange 22.

It will also be understood that during theforming operations of the blanks 19, 80 and 8| the end edges thereof are shaped along the dotted lines 88 to providefor the inwardly oifset flanges I. This forms the complete lining for the cabinet, it being noted that the parts are securely welded together along their intersecting edges. The inner surface of the lining is then painted a or vitrified or otherwise finished to provide for the desired internal surface.

Prior to the assembly of the cabinet, the frame 2| surrounding the opening for the refrigerating unit is assembled to the inner casing and secured to the flanges l3, l8 and 23 in the manner previously described, the molding 24 having a portion thereof extending between these flanges and the frame 2|.

In the assembly of the cabinet the frame 8 is first positioned within the outer casing A and the insulation material ll. l5 and I8 forming the bottom, side and top insulation is next inserted. The inner casing B is placed in position within the insulation material and secured along the continuous flange to the frame 4. When this is done the cabinet is, of course, supported on its front face to permit an easy assembly of these parts. After the inner casing is in position the end surfaces of the insulation material l4, l5 and I8, and the surface of the back I! of the inner shell are coated with the plastic sealing material 28. Subsequently the narrow panels 3| surrounding the top and sides of the frame 2| are placed in position and the back insulation material 28 is placed in position. The surface of the back insulation 26 is provided with the sealingmaterial 29 and the back panel 33 is assembled by inserting the same between one of the flanges 5 of one side portion and insulation material at that side and then sliding the same transversely to locate the panel underneath the opposite flange 5, and in which position the screws 35 are inserted. Subsequently the horizontal insulation material 28 is positioned between the frame 2| and the back panel 33, and this insulation material is coated with the sealing material 28 and the horizontal panel 38 is placed in position over the insulation material 28 and the end of the back panel 33. The flange 34a which forms a continuation of the panel facing 34 is then bent over and downwardly against the panel 38 to assist in locating the same. The guides for the refrigerating \mit are then assembled by means of screws 38 which extend through the bent-down portion of this flange 33a through the panel "and into the back panel 33. The straps 42 which form the support for the back housing 45' are then assembled, and the insulating panel 48 is disposed over these straps and clamped in position by means of the screws which secure thestraps to the frame 2| and the screws 43 whichsecure the housing to the straps.

After the two shells A and B are thus assembled, the door molding I8 is then snapped in place, and the door which has been previously assembled is then mounted, after which the cabinet is mounted on its base.

The refrigerating unit can then be assembled and this is done by merely inserting the same through the door opening and entering it on the guides 38 and sliding the same rearwardly until the flexible gasket 58 engages with the face of the inner casing that surrounds the frame 2|. The angle clamps 58:! are assembled on the screws 58 and the nuts 55 then tightened to clamp the gasket 54 between the edges of the opening 2| and the flange 51 of the refrigerator unit.

The refrigerator cabinet described is of rigid construction throughout by reason of the particular manner of joining the various parts and is efiiciently insulated throughout, eflicient sealing gaskets being provided around the door opening and around the opening which receives the refrigerating unit.

The method of forming the inner and outer casings provides for economical production and increased rigidity of the stmcture.

Aside from the specific embodiments of the invention herein shown and described, it will be understood that numerous details of the construction may be altered or omitted without departing from the spirit and scope of this invention, and it is not the desire to limit the invention to the exact construction herein set forth, but to claim the invention broadly as well as specifically as indicated in the appended claims.
