CORPORATION OF NEW YORK METAL oAnnvnr Application filed June 1927. Serial no. 197,281.

My invention has particular reference to metal furniture, one of the principal objects being to provide a stout, handsome, ornamental cabinet'which is readily formed of simple strength and rigidity.

Metal cabinets "are particularly advantageous for certain uses, such as the housing of apparatus of the nature of radio receiving devices, because of the advantages to be ob- I tained from the shielding of the set by the metal of the cabinet as well as the excellent protection afforded against physical injury from shock and like accidents. It -is,however, essential that.radio cabinets be handsome, finely finlshed articles of furniture, and

i that they likewise be stout, durable, rugged cases. Accordingly, such cabinets have 1nv the past been. produced almost exclusively from wood, to obtain the necessary handsome appearance, even though it necessitated the sacrifice of the physical strength which is obtainable from the metal, and of the advantages of the metal for. the electrical shielding, or necessitated the inclusion of an auxiliary metallic lining. .A finely fitted and finished wooden cabine is an article of substantial cost, because of the necessity of the employment of highly skilled artisans in the manufacture, and of the large amount of hand fitting and finishing, which is unavoidable, no matter how large the quantity manufactured.

My invention vcombines the advantages "of both the wooden and metallic cabinets, without the disadvantages of either, and provides a cabinet having the handsome appearance of a wooden cabinet, as well as an equally-lightweight, and the advantages in strength, durability and electrical characteristics of a metal cabinet combined with means for the easy production inquantit-y, from simple easily made parts.

In accordance with the construction of invention, I provide a cabinet which. is formed of metal, having a'minimum number of simple parts, adapted to be, assembled with V a minimum oflabor and difliculty, with auxiliary strengthening members adapted to the production of additional ornamentation, and

and which when assembled has adapted to be enameled, lacquered, or otherwise finished for theprogluction of a hand-. some article of furniture. The cabinet of my inventionincludes a front panel member of insulating material, which may be of any of ,the preferred materials, such as bakelite or tents of the cabinet, as wellas means for deadening the resonant qualities of the metal sheets.

By the construction of" my device I have provided a simple, handsome, inexpensive,

durable cabinet, well adapted to a particular,

specialized purpose, as well as adaptable to a variety of other uses. 7

'Other objects and structural details of my invention will be apparent from the following description when read in connection with the accompanying drawings, wherein:

Fig. 1 is a top view partly in sectionof a preferred embodiment of the deviceof my invention;

Fig. 2.is section of the same embodiment;

a vertical frontview,part1y in Fig. 5 is a top view of the samecorner Ofo the same embodiment, and

Fig. 6 is a perspective view of the front top ra1l of the same embodiment.

The preferred embodiment of the device-of adapted to thesupp ort of the various electrical elements of a radio .receiv-in'gapparatus,

and having a hinged top adapted to .provide convenient access to the. electricalelements. The cabinet desirably consists of a minimum number of parts. jAccordingly, the back.

panel and the two side panels, with their top a width suitable to the reception of the anel' moldings and bottom moldings are formed from a single piece of sheet metal. The bottom panel and the front base molding like ,wise are desirably formed from a single piece. A top front molding is provided and also a top cover member, which is hinged to theback, at the top of the back molding. Four corner columns are provided and attached to the metal panel members, and a single sheet of metal. The top molding 4 and the bottom molding 5 are desirably formed in the sheet by a suitable stamping or bending operation, after which, by appropriate bending, the end panels are brought to the desired right angle relationship to the back panel. The top and bottom moldings are out at proper points tov permit the separation at the corners which is necessary in bending the sheet to form the right'angle corners as indicated in Figs. 4 and 5. Both the top and bottom moldings are formed with inwardly directed ledge members 6 and 7 for the sup port of other cooperating parts.

A bottom member 8 is provided, and a bottom front molding .9 is formed integrally therewith, by any suitable stamping or bend- -ing operation. The upper edge of the molding 9 is desirably formed into a groove 11 of which it is desired to use for the cabinet ront.

The bottom member 8 cooperates with the ledges 7 upon the lower moldings 5, and is supported thereby, thus producing a firm,

- stout, solid bottom to the cabinet portion.

In order to provide greater strength and stiffness, as well as for the production of a more handsome cabinet, corner columns 12 are provided. These are desirably formed, with one quadrant removed, as shown in Fig. 4 for the accommodation of the corner of the metal panels, and the moldings. They may be made in a rather plain outline, as

indicated in the drawings, or may take an desired ornate form, according to the pre erence of the user'. They are, desirably formed of castings in a light metal, such as an aluminum alloy, because of the greater with the outline of the top and bottom molding member 4 and 5, and they may be slightly longer in order to provide feet for the cabinet to stand upon, and to raise the bottom moldings 5 and 9 slightly-above the level of the surface on which the cabinet stands, as indicated in the drawings.

The columns 12 at the back corners make contact with the back panel 1 and the

side panels

2 and 3. The front columns 12 make contact with the

side panels

2 and 3, and also provide a ledge, in a planewith the front of the groove 11 against which the front panel 16 may abut. The panel 16 is then held in place against the front columns 12, partly by insertion within the groove 11 and partly by the clamping actionof a member 17 which is desirably formed of sheet metal and held by the screw 14 under the angle member 15 as indicated in Fig. 4. The member 17 may be a part of the sheet forming the

side panels

2 and 3, and integral therewith,'for tl ie extra strength thereby obtained. This construction provides a bottom .groove' for the'front panel 16, andside grooves, into which the panel may be inserted bysliding or otherwise as desired, either with or without the attached electrical elements of the radio set.

A front top molding rail 18 is provided,

which may be formed in a similar manner to in a similar manner to the moldings 4, and

is held in lace therein by a corner angle member 21, s ownin Fig. 5, which is attached both to the top molding 1 and the top molding 4 by screws 22. A suitable recess is prolar angle members may be incorporated at the ease of assembly. They may, however, be.

formed of any desired material which-cooperates properly with the other members of the cabinet.

The columns 12 may be assembled with the sides of the cabinet, and may be held in place by means of the screws 14indicated in section in Fig. 4. The holding screws 14 desirably pass through an angle member 15, positioned within the corner, for the purpose of providing a better bearing for the head of the screw, as well as for firmness and strength. The column members are appropriately formed at. top and bottom for cooperation vided in the top of the front columns 12 for the reception of the angle member 21, and it is concealed therein and within the body of the moldings 18 and 4, fitting into the internal horizontal U-shaped bead-forming grooves thereof, as indicated in Figs. 1 and 5. Simibottom ends of the front columns 12, if desired, or suitable fastenings may be inserted through the ledges 7 and the bottom member '8 for fastening the members together. A suitable cover or top member 23 is like-- wise provided, hinged to the back molding members 4. The cover member 23 may desirably take the form of two sheets'of metal, one thereof 24 being plane and formir. the

lower surface of the cover, the other 25 t ereof being'stamped or bentin any desired fashion to we a suitably ornate upper surface. This firming may simulate chamfered edges, or may provide any desired ornamentation, as by the simulation of carving, etc. The space between is desirably filled with a deadening material 26, which maybe corrugated'board or other suitable fibrous or pulverulent material, or on occasion may be omitted entirely. The deadening material-26 is, however, desirable since the closing of the cover imparts a shock to the members, which tends to set them into an undesirable condition of vibration, undesirably emphasizing the fact thatthey are formed of sheet metal.

The cover 23 is desirably hinged to the top molding 4 bya hinge 27 which may take the form of the so-called piano hinge. The fastening between the cover members 25. and 24 may be made in'any, desired way, which will be obvious to thoseskilled in the art. The parts may be. fastened by a'fol'ding of one about the other as indicated in the draw-- ings, or they may be joined by any other'suitable fastening of the prior art, such as by welding, riveting, soldering, brazing, etc. When thecover is closed it rests upon the inturned top ledge ,6 of the moldin 4 and upon the similar inturned top ledge of the top rail molding 18, as shown in the drawings. By the construction of my invention I provide a stout, durable, rugged, handsome cabinet, particularly adapted to the reception of radio apparatus, and to the provision of electrical shielding thereof by the metallic parts comprising the cabinet. The device of my invention further provides means for the dead-- .eningx of the resonance of the metal surfaces,

may beiincluded in one or more of the whic metal parts as desired. The cabinet of my construction furthermore is simple to assemble and inexpensive to manufacture.
