SHEET-METAL CASE cons'rnuo'noni 1 Application filed July 24, 1922. Serial No. 576,942.

I To all whom it ma concern:

Be it known that I, PETER M. WEGE, a

citizen-of the United States of America, residing at Grand Rapids, in the county of 5 Kent and State of Michigan, have invented certain new and useful Improvements 111 Sheet-Metal Case Construction; and I do.

hereby declare the following to be a full, clear, and exact description of the invention,

10 such as will enable others skilled in the art to which it appertains to make and use the same. 5 I This invention relates to a case construe tion, particularly adapted for metal filing 16 cases, though not in any sense lim ted exclusively thereto. It is a primary ob ect and purpose of the present invention to make a case construction'of metal at a minimum cost of production, making use of light gage 20 sheet metal and providing novel reinforclng structure for the case so that it is extremely strong and rigid and fully capable of withstanding the usage to which it is subjected in' service. The invention consists in many novel constructive details and arrangements of, parts for eflectively attaining the above named ends, as well as many others not at.

this time specifically set forth, but which will appear as understanding of the invention is had from the following description, taken in connection with the accompanying drawings, in which,

Fig. 1 is a perspective view of a metal filing case made in accordance with my invention. v

Fig. 2 is an'enlarged fragmentary vertical section taken in a plane paralleling the front or back of the case. p

' Fig. 3 is] a fragmentaryrear elevation of the case. I

Fig. 4 is afragmentary enlarged perspective view of the front of the case at one side thereof, parts being broken away and in sec-.

tion for better disclosure of the construction. k Fig. 5 is'fa fragmentary horizontal section, taken substantially, on the plane of line 5-5 of Fig. '4, and f I, I '6 are perspective VIEWS of re inforcing and sup rting brackets used in the front construction of-the case.

Like reference characters refer to like parts in the several figures .of the drawings.

In the construction of the case, two sides" of relatively thin gage sheet metal are provided, as indicated at 1, having portions 2 at their upper edges turned inwardly toward each other to make the top of the case, the meeting ends of said portions 2 being each formed with a downturned flange 3, said flanges lying alongside each other and permanently connected togther as by spot welding or otherwise. Each side at its lower edge is inwardly turned, forming a flange 4, on which flanges the case restson the floor. Each side at its forward edge is formed with an inturned vertical flange 5, as-shown, and each side 1 and top portion 2, at their rear edges are formed with inwardly and downwardly turned flange portions 6 which pass over the edges of a sheet metal plate 7 and are spot welded thereto, securing the back in the case. I

At each side of the front of the case, an angle-shaped member, each including an inwardly extending leg 8 and a leg 9 positioned at right angles thereto, is positioned, so that the legs 9 come against the flanges 5, heretofore described, being spot welded thereto. Adjacent the lower end of the case, a bottom 10 of sheet metal is located, at its front being formed with an integrally connected and downturned portion .11 which reaches to the floor.

At the front edges of the top portions 2, flanges 12 in alinement are bent downwardly, associated with which "is ajsecond angle-shaped member formed. withan inwardly extending horizontal leg 14 and a vertical leg 13 which lies'against the'front sides of and-covers the flanges 12. [An angle shapedreinforcing bracket comprising arms 15 and16located atright anles'to each other'is located at each upper ront corner of the case, the arms 15 lying back of the flanges 12 at the ends-thereof andthe arms 16 extending downwardly back of the flanges 5. By spot welding the flanges, 12

and leg 13 are permanently connected, and in the same manner the arms 15 and 16 are permanently connected to the flanges 12 and 5, respectively. 7

At different points in the length of the inwardly extending flanges or legs 8, horizontal slots 17 are cut for the passage of inwardly extending parts 18, horizontally positioned at the lower endof a second part 19 which is turned upwardly from the front edge and at the outer end of the part 18 and lies against the rear side of the adjacent flange 5 to which it is permanently secured by spot welding.

At the different points where the parts 18 extend inwardly as described, horizontal cross bars are located, made from sheet metal by doubling a piece of sheet metal lengthwise upon itself thereby forming an upper side 20 and a lower side 21, the bend being at the front edge of the bar as best shown in Fig. 4. The parts 18 extend into the space between said upper and lower sides of the bars at the ends thereof. Rails 22 of 'the form shown are positioned horizontally alongside the sides 1 of the case for .carrying drawers adapted to be inserted therein and the front ends of said rails, the cross bars at their ends and the parts 18 are perma nently connected together by spot welding, the rails also having similar connection to; the legs 8.

A construction made as described is rigid and strong and fully capable of withstanding hard usage. The gage of metal required is very thin compared to what has formerly been considered necessary, and the cost of manufacture is correspondingly reduced. The bracket reinforcement, combined with the cross bar and drawer rail constructions make the construction one which does not spring or warp out of form, extreme strength and rigidity for the thin metal used being attained The structure is also complete in appearance, in every Way fulfiling the requirements for metal filing cases.

. ()f course the same or similar construction inwardly extending leg, said inwardly exmay be utilized for desks or other articles havingdrawers. The appended claims define the invention and I consider myself entitled to all forms of structure coming within their scope.

I claim:
