Specification of Letters I'atent. "'Pfitentd Fel 25, 1919.

Application filed March 5, 1918. Serial No. 220,451.

To all whom it may concern:

Be it known that I, ROBERT G. PmKINe- TON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Sheet-Metal Construction, of which the following'is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification. t

The present invention relates to sheet metal construction. My invention provides a system of sheet metal construction characterized by facility and rapidity of erection and dismantling. The construction is of the sectional, panel type and the various parts thereof are standardized and-interchangeable. The system comprises formed,

sheet metal panels and cooperating supporting members which can be quickly and Y easily assembled and dismantled.

More particularly the invention comprises the mode of attaching these panels to the supporting members and the particular construction and arrangement 'of the supporting members to the end of rapid and easy assemblage and disassemblage. A further, but highly important feature, is the manner of forming the attaching beads so that the same is internally braced.

My improved system of sheet metal construction has a wide range of utility. I contemplate its employment for the construction of portable houses, emergency or permanent buildings, walls, partitions, booths, collapsible containers vehicle bodies, signs, etc. A structure built by my improved system of sheet metal construction has all the advantages of lightness, strength, portability, facile erection and dismantlm smooth. attractive finish, and in addition 15 substantially fire and sound proof. 'These characteristics will convey some idea of the I broad field of utility of my improved system.

' A preferred adaptation of my improved system is to the construction of portable houses, emergency buildings,walls and partitions. I have illustrated in the appended drawings and described in the followin specification, one particular adaptation o my improved system of sheet metal construction as applied to the erection of buildin walls or the like.

alls or partitions can be erected by my system in permanent buildings constructed '11 and 12. The flanges 11 and 12 of ,the\ usual standard materials, or a. complete house or building can be fabricated from the standardized parts of the system. The walls can be increased along any dimension by the mere addition'of anel sections and supporting members. T e labor and tools required In the erection of any'part of my system are a minimum. -A screw driver is the only tool necessary to apply one particular form of panel to the supporting members. No tools whatever are re uired for applying a modified type, which is merely pushed or snapped into place in the supporting members. The latter type of panel is peculiarly adapted to houses or buildings containing explosives, as it will disengage from the supporting structureand relieve the same in the event of an explosion within the building, but is practically irremovable from the outside of the building.

The different members of the supportmg structure are constructed and arranged to facilitate the installation of electrical conduit in the wall. The rigidity of theassembled wall is assured by interconnecting the supporting members. In the drawings A Figure 1 1s a sectional view of a portion of a wall erected according to my system of sheet metal construction.

Fig. 2 is a similar view showing a corner of a wall. r

Fig, '3 is a sectional view of a wall employing the interlocking panel.

Fig. 7 is a fragmentary elevational view of the interlocking panel and frame construction'illust-rated in Fig. 3. I a

Fig. 8 is a fragmentary sectional view of a modified form of supporting structure adapted to receive both types of panel, and

Fig. 9 is a. detail section illustrating the bead as being screwed to the panel.

Referring to Figs. 1 and 5, a supporting structure is first erected, consisting of a plurality of open rectangular frames desi nated 9. Each frame is made of channe or channel members and each comprises the web 10 and the straight and oblique flanges ro ect inwardly and laterally from the we per tion around the entire perimeter of the frame. V

I preferably construct each channel of four frame bars formed out of flat bars, by

5 pressing their margins to form the flanges the building structure, which may consist of the flooring and ceiling or the sills and joists, as the case may be. In frame units of a standardized size these holes will have a definite location and spacing. Thus the 2 holes in the sides of adjoining frames will aline, enabling the several frames to be all interconnected by bolts passing through the side webs, as shown in dotted lines in Fig. 5. The frames may be superposed one upon the other, or the wall may be expanded in any direction by merely bolting the adjoining frames together.

he web 10 is provided with a central opening 21, at the top, bottom and on each side of the frame, adaptedfor the installation of electrical conduit or cable. The openings 21 of the several frames will always register and through these the conduit can be strung to any desired part. of the wall.

As shown in Fig. 1, where the wall terminates or two walls intersect, a special frame is employed, one side of which has a relatively deep channel designated 22. Each side of th s panel is ribbed as shown at 23 scribe.

The channel 22 may be provided as an independent unit, adapted'to be bolted to hereinafter describe. 4

After the frameshave been erected,'and have been bolted to their supports and to each other and the conduit strung, the panel sections 24 are applied. As illustrated in section in Fig. 1. these panels are composed of thin sheet metal and have beads 25 either integrally formed along each edge. or applied as a separate head 66. as shown in Fig. 9. These beads are preferably, though not essentially. triangular in section, their ends being preferably .arranged at substantially to each other. In forming them I preferably fold the edge 26 of the metal sheet to providea plurality of facets 26'. folding the exposed edge facet into the interior of the bead so that it lies along the inner surface of .the panel and has its extreme or free edge wedged into the corner 27. The compression strength is greatly increased in 66 this triangular formation by the internal for a purpose which I shall hereinafter dethe floor, ceiling or adjacent wall, as I shall bracing of the edge or marginal portion, and the bead is more staunch against crushing and deforming than would be a circular bead of corresponding size.

While other forms of beads on the sheet 24 would cotiperate with other features of my invention, I have shown the beads as being triangular in section, as this section best illustrates my invention.

Atthe corners of the panels 24 the vertiflanges 32 and the parallel spaced flanges 33.

A plurality of openings 34', equi-distantly placed along the web of the strip, are provided for the insertion of the screws 34 which tap into threaded openings 34' between abutting panel sections.

These openings are formed by "indenting the web 10, as shown at 35 in Fig. 6. The indentations of adjoining frames match and after the frames are bolted together the hole thus formed is tapped for the reception of the screw 34. These," threaded sockets are spaced in accordance withthe spacing of the screw holes in the strip 30. j v

.By tightening up the screws 34 the triangular beads 25 are cammed in along the oblique flanges 12, thus drawing the panel section taut from both side edges. A modified strip 30 is provided for cooperation with the rib 23 along the side of the'end frame. An oblique flange 33 (Fig. 1) bears upon the inclined face of the rib. A screw bolt 40 passes completely through both strips 30 and threads into a cap nut50.

I preferably round the corners of adjoining walls as shown in Fig. 2. Here I erect a supporting frame structure 36 composed of the independent studding channels placed back to back and either spot welded or bolted together, and upon which I mount the 115 curved panel sections 37 and 38. These parts are all carefully standardized, similarly to the frames 9 and panels 24. The

studding channels of the frame .36 are of the same general cross section as are the members of the frame 9.

The corner panels, which receive the curved panels 37 and 38, are interconnectedat their ends by curved brackets 41, secured to the floor and ceiling. These brackets comprise the arcuate web 42 and the two vertical extensions 43, bearing against the channelsof the studding members 36. The brackets are reinforced by ribs 44 and have apertured bosses 45 (Fig. 6) adapted to register with the lowermost holes 14 in the webs ofthe frame members. Angle brackets 47, having similar ribs and bosses, are disposed in back of each framemember. The angle brackets are bolted to the building structure by the bolts 48, and are clamped to the frame members and the corner brackets 41 by transverse bolts 51. The application of the curved panels 37 and 38 to the frame members 36 will be apparent from the foregoing description.

In lieu of the frames 9, the supporting frame structure 36 may be composed entirely or partly of the studding channels and angle brackets 47. I have illustrated this in Fig. 3, in connection with the modified form of panel bead which I shall now describe.

Referring to Figs. 3 and 7, the frames 53 designed for receiving the interlocking type of panelbead, are substantially the same as the preceding frames 9,, with the. exception that the inclined flanges 54 are folded back toward the straight flanges 55 to form an acute angle between the flanges. Both .types of frames can be formed from the same sized blanks. The flanges of the independent studding channels 56 are also given this acute formation.

80 The modifiedpanel 57 has. its triangular beads 58 formed so that a corner of the triangle can be snapped into the acute recess between the flanges 54 and 55. The natural resiliency'of the sheet metal panel enables 85 it to be snapped over the inclined flanges 54 by giving the edges of the panel a quick,

' sharp push. The edge 61 of the sheet metal is turned into the interior of the bead andis wedged in the corner thereof, similarly to the bead 25. v

- The flanges 54 and 55 are cut away at the corners of the frame as is shown. at 625 in Fig. 7. The corners of the panels 57 are formed as were the corners of the panels 24.

This form of panel has the advantage of Y requirin 'no screws, strips or tools in its application. It is particularly adapted for the outer siding of a wall. Its removal can be effected only by pushing outward from within the supporting structure, unless provision therefor has been. made in the nature of holes or lugs in the panel body intended for the application of a suitable tool.

I find it advantageous in the erection 9f exterior walls to use supporting members such as are illustrated in Fig. 8. and to apply the panels 24 to the inner side of the structure and the panels 57 to the outer side. The

advantages of both types of panels are thus 2 I the margin of said panel, said head being in- 125 obtained.

As shown in Fig. 3, I propose erecting a supporting frame structure composed of studding channels similar to those used in erecting the frames 36 or 56 and angle 55 brackets 64. The pairs of studdifig channels are placed back to back and are spot welded or bolted together. The pair of channels forms a composite supporting member which is secured at each end to the building struc-v ture by either one or two angle brac ets 64. With this arrangement the upper and lower beads of the panel would engage with .a channel roughly similar to the channel 23 of Fig.1, which would be bolted or otherwise secured to the floor and ceiling. The channel 22 would of course have either oblique or acute flanges in conformity with the studding channels. This construction has greater flexibility-of arrangementand disposal than is possible with theframes 9 and, 53. Different sized panels may be utilized, and moreover the wall may be distorted to clear obstructions,

Obviously, windows and doors may be embodied in thepanel sections.

The completed wall presents a neat, finished appearance and is fireproof, substantially soundproof, and can be easily cleaned.

It will be apparent that my improved construction. is capable of extensive modification and re-arrangement, but I intend that all such deviations be construed "as coming within the spirit and scope. of the appended claims: 1
