WINSLOW, OF SHAKER HEIGHTS, OHIO, ASSIGNOR 'IO THE MILLS COM- PANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO SHEET-METAL PANEL .Application filed September 11, 1930. Serial No. 481,157.
This invention relates to Vsheet metal constructions, and more particularly to sheet metal panels which are suitable for, or employed in the production of, doors and par- 5 titions.
It is the general object of the invention to provide a construction of this character which will enable such panels or partitions to be constructed from a minimum number of 10 like or identical units; also to construct the units in such manner as to enable tWo Such units to be quickly and conveniently assembled. A still further object of the invention is to provide means whereby said panels may be constructed at a. comparatively low expense and with rapidity of production and ease of assemblage.
I secure the foregoing objects .and other objects which appear hereinafter, through the construction and arrangement of parts shown in the drawings, wherein Fig. l represents a perspective view of a panel constructed in accordancewith my invention; Fgis. 2 and 3 are details in section corresponding respectively to the lines 2-2 and 3 3 of Fig. 1; Fig. 4 a view, similar to Fig. 2, show-` ing the units in the positions which they 0ccupy` during the assembling operation and prior to the interlocking of the flanges; Fig. 5 is a plan view of one of the units, the other unit being shown in dot-and-dash line and the units occupying the positions shown in Fig. 4; Fig. 6 a. side elevation of one of the units; Fig. 7 a sectional view through one of the units, corresponding substantiallyA to the line 7 7 of Fig. 5; and Fig. 8 a sectional detail showing a modification of the joint shown in the preceding views.
Describin the various parts by reference characters, and B represent generally two similar sheet metal units which, when assembled, constitute the metal parts of a panel. Where the panel is square, the units A and B may be identical in the construction and arrangement of the parts thereof, thus requiring in fact the manufacture of a plurality ,of single units for the production of such panels. However, when the panel is rectangular in shape, as shown herein, two similar 0 units (a right and a left) will be required.
The unit A comprises a flat rectangular metal sheet 1 having one of its longitudinal edges and one of its lateral edges provided with a wide side flange, indicated at 2 and 3, respectively, and constituting two of the sides of the panel or. partition. Each of the side flanges 2 and 3 is provided with an end flange 2FL and 3a respectively, which end ianges are parallel, or nearly parallel, with the body of the sheet 1, to insure a closed joint, said anges extending beneath such body.
The opposite unit B is also provided with a flat rectangular metal sheet 4 of the same dimensions as the corresponding sheet of the unit A and having at one of its longitudinal edges a side flange 5 and at one of its lateral edges a side flange 6, each of the flanges 5 and 6 having a flange 5a and 6a, respectively, which are parallel with the body of the sheet .4 and extend thereabove.
In addition, the panel A has the metal at the edge opposite the edge 3 provided with a U-shaped seat formed by bending the entire length or width of the metal at such edge y backwardly upon itself beneath the under surface of the sheet 1, as shown at 7 and then bending such metal upon itself to provide a flange S'eXtending outwardly parallel with the part 7, and forming a grooved seat 9 therebetween-see Fig. 4. It also has the lateral edge opposite the side 2 provided with a similar seat, the parts 10, 11 and 12 corresponding respectively to the parts 7, 8 and 9 of the seat just described-see Fig. 3. The distance of the first bending edge from the body of each sheet may be varied by folding the edge over any thickness of spacer, to bring the exterior joint at the desired. 10- cation on the edge; see Figs. 4 and 8.
The edge of the sheet 4 which is opposite the edge (iis provided with a U-shaped seat similar to those just described for the sheet 1, the parts of the seatbeing indicated at 13, 14 and 15; and the edge of the sheet 4 which is opposite the edge 5 is also provided with a U-shaped seat similar to those hereinbefore described and the parts of which are indicated at 16, 17 and 18-see Fig. 3.
In order to permit the folding of the metal to form the U-shaped seats, the corners of each sheet are first cut away so as to enable the metal, when folded into such U-shape, to present beveled edges at the ends of both seat flanges, such as shown at 13a and 16a.
With the parts constructed and arranged as described, the inner surfaces of the sheets or panels l and el will be coated each with a suitable adhesive, as glue, indicated at C. A pad D of insulating material, such as corrugated cardboard, or porous fiber, is secured to the inner face of one of these sheets, after which the other unit is applied on top of' the pad, in the manner indicated in dot-anddash lines in Fig. 5, with the side flanges of one unit registering with the U-shaped seats of the other unit. Then, by a short movement in a diagonal direction, as indicated in Fig. 5, the u-nits A and B will be assembled, together with the interposed insulating pad D. Ihe pad D may, as shown, cover theientire space between the units; or, if' desired, it may be partly or entirely eliminated.
rlhe corners between the side flanges 2 and 3i and between the side flanges 5 and 6 may be closed by solder or anyofI the well-known metal fillers and, after the units with the interposed pad shall have been assembled, the other corners will preferably'be closed in the same manner.
In Fig. 8, there is shown a modification of the invention wherein the flanges and U- shaped seats are formed at a distance from the bodies of the sheet metal units. In this View, one of the flanges of the sheet metal unit A is indicated at X and one of the U-shaped s eats of the unit B is indicated at Y. It will be noted that the joint formed between the two units is here shown as approximately half the depth of the edge of the assembly. As is the case with the form of my invention sl' lwn in the preceding views,
two ofthe adjacent side edges of the unit A will be provided with the flanges X while the other two will be provi ded with U-shaped -f seats similar to the seat Y. In like manner,
two of the adj arent edges of the unit B will be provided with the U-shaped seats show-n in Fig. 8, while the other two edges will be providedwit-h flan similar to the flange X.'
Due to the manner of constructing the parts entering into the construction of? each panel, it is possible to construct such panels from sheet metal and with a minimum of expense, due to the fact that, at most, only one pair of like sheet-metal units will be required foreach anel; and, in the event that the panelsv are to be square in outline, then only one set of units need be constructed. Furthermore, by this construction, I am enabled to produce a flush' panel, which may he used as a door or partition, and to secure this result by interlocking two like metal units.
Having thus described my invention, what I claim is:
1. A panel comprising a pair of sheet metal units each comprising a rectangular sheetmetal body having integral sides projecting from two adjacent edges, each side having at the end remote from the body of the sheet a flange extending from such edge substantially parallel with the body of the sheet and toward the edge-of such sheet which is .opposite the said flange, and each unit also having each of'its other two edges provided each with a U-shaped seat adjacent t0 the inner surface of each such sheet and formed byv bending the metal at each such edge backwardly beneath the body of such sheet and then outwardly, the flanges provided on the sides of each unit being adapted to enter the U-shaped seats of the other' unit whereby the units may be assembled by a diagonal movement of one unit with respect to the other after registering the flanges with their respective seats. t
