Application March 17, 1945, Serial No. 583,197
1 Claim. 1
My invention relates to strip material, and-the principal object of the invention is to provide strip building material of such character that it can be coiled suificiently flat for shipping and then uncoiled and cut to desired lengths for' convenient in use, easily installed in a working position and easily disconnected therefrom, economical of manufacture, relatively simple, and of general superiority and serviceability.
The invention also comprises novel details of construction and novel combinations and arrangements of parts, which will more fully appear ever, the drawings merely show and the following description merely describes embodiments of the present invention, which are given by way of illustration or example only.
In the drawings, like reference characters designate similar parts in the several views.
Fig. 1 is a vertical, sectional view taken on the line of Fig. 2.
Fig. 2 is an elevational view, looking in the direction of the arrow A of Fig. 1.
Fig. 3 is a perspective, broken view of material embodying the foregoing objects.
Fig. 4 is a view similar to Fig. l, but showing insulation used on the inner face of the material.
Referring more in detail to the drawings, the form of my present strip material shown in Figs.- 1 to 4 comprises a plurality of longitudinal, parallel convex portions 5 and 6 connected by an intervening, concave trough l. The edges 8 and 9 of the material extend beyond the plane of the inner face of the trough l, as perhaps best shown by the lowermost strip H) in Fig. 1. The edges 8 and 9 engage the supporting structure or studding l2, while the trough portion 1 provides spanning means for resiliently connecting the edge portions 8 and 9.
A nail I3 is driven through an aperture H1 in the present material and into the supporting structure l2. The head of the nail l3 engages the convex portion 5, and upon the nail being driven in farther, it places tension on the strip by flatin the course of the following description. Howtening the convex portions 5 and 6 to a limited extent and by flexing the trough portion 1 inward from the broken line position 15 to the full'line position iii, in Fig. 1. This places tension on the edges of the strip material, which provides closer engagement of the edges 8 and 9 with the supporting structure. The amount of tension is that which is necessary to maintain contact between the upper edge of the strip and the supporting structure and contact between the lower edge of the strip-with the next lower adjacent strip. The amount of tension depends upon the resilience and flexibility of the material employed. The resilience and flexibility in turn depend upon the temper of the material and also upon its thickness. I Y
The edge ll of the next upper strip l8 engages the trough l of the lowest strip H3, which makes a close fitting weather-resistant overlap between the edge I! and the trough 1. The nail I9 of thenext upper strip is driven into the supporting structure I 2 until its trough flexes from its broken line position 20 to its full line position shown at 2!. The edge 22 of the third strip 23, counting from the bottom, engages the trough 2l'of the second Strip l8, and a nail 24 driven through the third strip 23 and into the supporting structure l2, places the third strip 23 under tension by flexing its trough 25 inward toward the supporting structure !2. This arrangement is continued successively throughout the area covered.
The materialof which my strip material is made is preferably a low carbon, cold rolled, simple steel that is relatively thin; e. g., .012 to .015 in thickness. This material is quite flexible and resilient since it is used in the full-hard condition; i. e., in the as-rolled condition. Of course, high carbon steel may also be used, but it would materially, and, it is believed without commemsurate advantage, increase the cost of my material. If plastic material is used instead of steel, of course, the thickness will be substantially greater than that given. Of course, whether steel or plastic is used, it is to be understood that the material is to have suflicient resilience and flexibility to maintain contact of the edges of the strip with the next adjacent strip and with the underlying structure. Moreover, composite or bimetallic materials can also be used provided they have the foregoing characteristics; e. g.., where rust resistance is desired, a bimetallic metal may be employed such as ordinary lowcarbon steel which has been masked with a thin (approximately .002 inch) lay of copper.
Any suitable insulation may be employed with used, it can be glued to the back of the siding.
The insulation may be in block form and disposed between the studding l2 and the siding 23, as shown at 26 in Fig 4, or it may be in blanket form as suggested at 28. If loose insulation were used, a covering material (not shown) could be employed on the studcling, so as to provide a space for the loose insulation between the covering for the vstudding and the instant siding. It will be noticed in Fig. 4 that insulation may be omitted from within the smaller convex portion 29, in order to provide space into which the insulation 26 may be pushed, in order that the trough 25 may flex inward with a minimum of resistance.
It will be noted that in each form the strips overlap sufliciently to cover the nail holes, in order to maintain the tight condition.
The material from which the present strips are 7 cut is coiled up for shipment or storage. The convex portions flatten when the flexible steel material is wound in a coil. Then upon unwinding for cutting and use, the material, due to its inherent resilience, resumes the shape shown in the drawings. The material is under tension when flattened in a coil, since it was originally rolled with one of the present convex-concave shapes or one similar thereto, and the material resumes that form when released from the tension imposed upon it by the coil. Another advantage is that the user can cut from the coil 'just the desired lengths. thus afiecting savings in material by minimizing waste. In addition, the convex portions strengthen the material laterally and thereby permits the use of lighter gauge material.
The strip material is preferably processed and rendered rust-proof by the following process:
(1) Cold roll the strip to the desired thickness;
'(2) Edge the strip in order to eliminate sharp edges; 4
(3') Punch the nail holes at predetermined spaced intervals;
(4') Electro-galvanize the strip;
:(5) Bonderize the strip;
(6) Enamel and bake the strip;
(7) Form the strip to the desired cross-sectional contour.
The present material has many uses. such as for construction purposes, including siding for buildings of all sorts, store fronts, facades, roofs, inside wall surfaces, and many other uses in and out of the building industry.
While I have illustrated and described what I now regard as the preferred embodiments of my invention, the constructions are, of course, subject to modifications without departing from the spirit and scope of my invention. I, therefore, do not wish to restrict myself to the particular forms of construction-illustrated and described, but desire to avail myself of all modifications that may fall within the scope of the appended claim.
Having thus described my invention, what I claim and desire to secure by Letters Patent is:
In building material, a plurality of flexible strips having relatively smaller convex portions and relatively larger convex portions connected laterally by concave portions, the longitudinal edges of the strip extending beyond the plane of the inner face of the concave portion. the lateral edges of the strip being unflanged and positioned in the same curved plane as the body portion of the strip, with the edge of the larger convex portion in the concave portion of an adjacent strip, fastening means to secure the smaller convex portion of the material to a supporting structure arranged to tend to flatten the material by the securing operation, the next successive strip covering said smaller convex portion and its fastening means.
