To all whom t may concern.'

Be it known that I, FOREST V. DETWILER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Refrigerators, of which the following is a specification.

This invention relates to improvements in refrigerators and more particularly to the construction thereof and the primary object of the invention is to provide an im-,

proved .'.rnetallie refrigerator of sectional construction and one in which the sections may be all shaped or formed and then assembled to produce a refrigerator of any desired size.

A' further object is to provide improved means for securing the various sections and parts together.

A further object is to provide an improved refrigerator which will be thoroughly insulated and improved means for holding and securing the insulation or packing in position whereby the insulation will be prevented from settling which would produce an air space within the walls of the construction' after the refrigerator has been completed. p

A further object is to provide an improved metallic refrigerator which will be simple, durable, cheap and light in construction and eilectiveand etlicient in operation.

To the attainment or' these ends and the accomplishment of other new and useful objects, as will appear, the invention Consists in features of novelty in the construction, combination and arrangement of 'the severalparts hereinafter more fully described and claimed and shown in 'the accompanying drawings, illustrating an embodiment of the invention and in which- Figure l is a detail perspective view of a refrigerator of this character constructed in accordance with the principles of this invention.

arranged at the rear corners ofthe refrigerator, as shown niore clearly in Figs, 4 and 12 of the drawings. These uprights may be constructed of any suitable" material such .as wood or the like, `and are of a height Subi stantallyl lequal to the 'height of` v*therefrigeratorl'abov@ the base, andj'each ofv they...A -'uprights is provided on its outer face with1 a plurality of grooves or kerfs43 which are spaced freineaeh otherso ,that when theV sides are constructed the flanges 21, 2,2-, at

the rear extremities hereof may be inserted Withinr the respective .kerf 43 and the kerfs are of such a length as-to permit they extremside sections to slightly ity of each of the overlap the outer face ofthe upright.y as shown more clearly in Fig. 4, and these parts may be held against displacement when thus assembled in anydesired or suitable manner, preferably by means of fastening devices passing through suitable apertures 44 in the sections 20.

The/back of the refrigerator, designated generally by the reference numeral45 in Fig. 4 0f the drawings, is constructed of

scctions

46, 47, shown more clearly in Figs. 7 and 14 of the drawings. The section 46 is of a U-shaped formation and is provi ded with slots or apertures 48 adjacent the extremities thereof and in each of the side walls at .the portion which forms'the a point in proximity'to the bottom of the section. The section 47 is shaped to form a panel intermediate the sections 46 and is also of a substantially U-shaped formation. The extremities of the sides 49 ofthe panel section are preferably bent back upon themselves as at 50, shown more clearly in Figs. 7 and 14, to form lips under which the extremities of the sides of the sections 46 are adapted to engage when the

sections

46 and 47 are placed together. The extremities of the panel portion 47 are slotted as at 5l (see Fig. 7) and the ends of the panel portion intermediate the flanges 49 are offset -as at 52 and deflected laterally as at to form a flange which is spaced slightly above the body portion of the panel 47. The panel sectionsare slotted at 51 while the panel is beingformed and before the side flanges 49 are shaped and during this step of the formation of the panel portion side flanges adjacent the extremities of the panel section Aare stamped or cut away as at 54 tol form a projecting ear or extension 55, which is' adapted to project laterally beyond the outer face of the side flanges 49 when the Y extremity of the panel is offset at 52 and i the side so*l A portion 52 and are flanges 49 are shaped. 'One of these projecting portions 55 is preferably arran d at each corner of the panel piece, pre erably in the same plane as the offset adapted to project through the slots or apertures 48 in the sections 46 when the parts are assembled and then flanged or bent down against the inner face of the sides of the sect-ions 46,'as shown at 56 in Fig. 14. lVhen the sections comprising the back are thus assembled and secured together the laterally deflected ex- ,I in th tremities '53 of the panel sections will stand e same plane as the body portion of the sections 46. The back thus constructed may be formed of any desired height preferably of a, height equal to the height of the Fig 13)v and this dowel or sides of the refrigerator and thevback is secured in position in the same manner in which the rear extremities of the sides are secured, that is, the edges of the interengaging flanges are adapted to be inserted in the kerfs 43 in the uprights 42 and the back is held against accidental displacement'by means of suitable fastening devices adapted to pass through suitable apertures 57 in the flange 53 and the extremities of the sections 46. Similar uprights 41 are adapted to be arranged at the front corners of the refrigerator and the forward extremities of the sides 39 of the refrigerator may be secured thereto in the same manner in which therear extremities are secured to the respective uprights 41. y

Metallic corner pieces 58 are provided and are of substantially L-shaped conliguration. The lower extremities of these corner pieces are deflected as at 59 to form inwardly projecting nanges and these corner pieces are adapted to be inserted in the castings 33 so that the sides of the corner pieces adjacent the bottom thereof will engage the sides of the casting and the flanges 59 will rest upon the flange 37 on the casting 33 and these corner pieces may be held against displacement with respect to the castings by means of the fastening devices 37a which pass through the apertures 38 in the flanges 37 and into the filler 31A-of the base and which pass through apertures 60 in the flanges 59. These corner pieces 58 are preferably of a height substantially equal to the heightof the corner pieces 41, 42 and are adapted to overlap the edges ofthe sides and backsy where they engageand are secured to the uprights 41, 42, as shown more clearly in Fig. 4 of the drawings. l

A suitable projection 61, such as a dowel pin .orthe like, extends below the bottom of'the uprights 41, 42 at each corner, (see projection/ 6l is adapted to be inserted in registering apertures 62, 63 respectively in the llanges 37 of the casting 33 and the flange- 59 ofthe corner pieces 58 'so that the upright will be held at its lower extremity from displacement and the corner pieces may also be secured aga-inst displacement by means of suitable fastening devices, such as bolts or rivets 64, (see Fig. 1) which pass through the corner pieces 58 and into the uprights, andfastening devices 65 which pass through the castings 33, corner pieces 58 and into the uprights 41, 4 2. The rear corner of one of the uprights at each corneiof the refrigerator, preferably the upright-41 is beveled or cut away for its ent-ire length as at G6 for a purpose to be set forth', and the flange 37 on the corner piece 33 is provided with a -threaded aperture 67 as shown more clearly in Fig. 5 ofthe drawings for a purpose to ti'einity T3 of the tie vas already describe@ upon the top edp'es of thel upriglits 4l, 42,A

It will also be apparent in o shaping and formingl the various panelsand sections, one set of dies may befused to construct a refrigerator ot' a largehor srnall'gsize, the panelsV will be shaped by one set offdiesand having been constructed of "they, ,desired length the extremities of the pa'nelsare successively inserted or placed between,suitable cuttingand shaping-'dies which stamp, pert'orate` and bend the ends into'tfrhe desired shapes. This is possible bythe it'aet-y that the panels are all' ofthe same height, the i length only varyingr when it is desiredto construct a refrigerator of -a greater cross sectional area andthe refrigerator may be builtx or constructed of any desired height by adding any suitable'number of panels or sections thereto.

t is, ol course, tol be understoodtbat suit able paekinfe,r ymaterial may be provided at any desired point to v' cover or protect the joints between sections Whenever it is found necessary and it iS also to la: understood that if it is found necessary the flanges of the metallic sections may be provided with a suitable 'coating of white or red lead or any other suitable waterproofing material to form air tight joints between these sections. `With this improved construction it will also be apparent that the insulating material 27 for the walls 0f the refrigerator will be supported by the ribs formed by the abutting flanges of the wall panel units7 and by providing these spaced supports for the insulating material throughout the height of the wall, the insulating material will be prevented from settling or packing down in the walls, which packing or settling would permit an air space to be formed in the ivalls at the top or above the insulating material. Furthermore it will bc apparent that the front section is detachably secured in" position so that the entire front wall section may be removed as a unit.
