METALLIC BUILDING UNIT 'Fi-led Aug. 28, 1939 BY 7 7 7 TTORNEY.

Patented July 29, 1941 UNITED STATES, PATENT QFFICE I v Q MEtitular:1 :31:30; UNIT; V Q I t r Eran k L Hes l,Hammond, I Application August 28, 1939, Serial No; 292,262 r (Cl. 189-86) v '3Claims.- This invention relates to an improved metallic building unit which is especially adapted for use n wstudding I! or sheathing on a buildingby means i of clips [4.

in covering the sides of buildings. The improved building =units of. this invention. are adapted to be interlockingly joined one with another, preferably in a horizontal. plane, whenapplied ;to a.

building or the like. ,It will be apparent, howi ever, that use of the improved siding of this intion resides in the provision of means for. forming a portion of an interlocking joint along each longitudinal edge of the improved member. The portions, when joined, form. a weather-proof joint extending the entire length of the joine portion. I

Anotherand .still further important-object of advantage residesin the provision of means for maintaining the joined portions of the associated members in immovable engagement. This immovable engagement between the interlocking portion of the members prevent moisture and dampness from collecting and causing rust and other discoloring. elements to spread over and deface the exposed surfaces of the associated members.

Still another object of advantage and importance resides in the provision of means for forming the intermediate portion of each member to compensate for expansion and contraction of the material due to climatic changes without disturbing or moving the interlocked edges.

A still further object of advantage and importance resides in the provision of means whereby the exposed surface of the improved member may be embossed to: simulate a log or the like.

Additional objects of advantage and importance will become apparent as the following detailed description progresses. reference being had to the accompanying drawing, wherein Fig. 1 is an elevational view of a fragmental portion of a building showing building units which embody the invention positioned thereon.

Fig. 2 is a vertical section, slightly enlarged,

' taken on line 2-2 of Fig. 1.

Fig. 3 is a slightly modified form of the invention.

As shown in the drawing:

. in the drawing.

- Each member I0 is convex in section, as' is indicated' by the reference numeral I6, and is clearly shown in Figs. 2 and 3. The convex surface i6 is especially adapted and designed to carry embossing or'the like simulating logs or other articles. Structures covered with such log embossed members have the appearance of log buildings.

The members In are substantially strips or sections and the parallel edges thereof are turned to form flanges wand 20. The flangelB, at the upper edge of the member, projects outwardly and thence downwardly, as is best shown in Figs. 2 and 3. The flange 20 on the lower edge of the member I0 projects upwardly, as isclearly shown The upwardly projecting flange'iil of one member is adaptedto be interlockingly Joined with the-downwardly projecting flange l8 of an associated member when the members are positioned on a building. The interlocking flanges I 8 and 20 provide a weather-proof and sturdy joint.

Moreover, the curvature of the member I'll, being flexible, exerts a constant tightening pressure on the flanges and, because the curvature of the convex intermediate portion l6 of the member I0 is adapted to assimulate all contraction and expansion of the material due to climatic changes, the joint formed between the interlocking flanges l8 and 20 is immovable. In view of the fact that the flanges I8 and 20 are in im- The reference numeral Ill indicates generally movable engagement, the portion of the member therebelow is not subjected to discoloration from associated rubbing orchaflng parts. The members H) are applied to a. building by first securing the bottom flange in position. A slight pressure is then exerted on the surface of the member expandingthe width thereof slightly. The upper flange is then secured in place, preferably by the clip M. This application of the members under a slight pressure then utilizes the flexibility of the material in maintaining the flanges of the joints in constant engagement.

A slightly modified form of the invention is shown in Fig. 3. In this form, the flange I8 is slightly extended from the convex portion ii of the member Ill. The extension 22 provides a flat surface between the top of each convex portion I6 and the lower edge of the next associated member. The flat surface 22 is adapted filling packed into the cracks ated logs.

It will be apparent from the foregoing that herein is provided a durable and artistic building member which may be economically pro- 'duced and secured to a building, and when so applied give the building the appearance of a log structure.

It will also be apparent from the foregoing that herein is provided a weather-proof, flreproof, and vermin-proof siding which is especially adaptable for use on cabins, cottages, and other buildings which are vacant or unused over considerable periods of time.

It will be apparent to those skilled in the art to which the device appertains, that numerous changes and alterations in construction anddesign may be made all without departing from the spirit or scope of this invention. Accordingly, it is understood'that the patent granted hereon is not to be limited to the preferred embodiment here disclosed nor in any other slightly overlapping horizontal tiers, an interlocking hook-like flange formed along each iongitudinal edge of each of said metallic strips, the hook-like flange along the upper edge of said strips being disposed outwardly, the hooklike flange along the lower edge of said strips being disposed inwardly, the intermediate portion of said strips being of concavo-convex'fob mation whereby the flexibility of the metal may be utilized to maintain thehook-like flanges of associated strips in weather-tight engagement,

and hooked clips interlockingly engaged with the outwardly projecting flanges providing means for attaching said strips to a wall.

'2. In a wall covering comprising in combination a plurality of metallic strips and a plurality of hooked securing clips, each of said metallic strips being provided with oppositely disposed hook-like flanges along the longitudinal edges weather-tight association.

3..In a sectional wall comprising a plurality of horizontally positioned metallic strips, hooked clip means for securing said strips to a wall frame, each of said strips being of concavoconvex formation and having a flangealong each longitudinal edge thereof, the convex surface of said strips being adapted to be positioned to form the outer surface of the wall, the flange along the upper longitudinal edge of each strip being hook-shaped in section and being disposed outwardly, the flange along the lower edge oi; each strip being hook-shaped in section and being disposed inwardly, and the outwardly disposed hook-shaped flange along the upper edge of the strips being interlockingly engaged with the inwardly disposed hook-shaped flange along the loweredge of the next above strip to form a weather-tight Joint, said concavo-convex formation providing means for exerting a retractivepull to maintain the flanges in engagement.
