METAL GLAPBOARD SIDING FOR BUILDINGS Filed D80. 31, 1962 2 Sheets-Sheet 1 INVENTOR.

LOUIS MARTIN MAHONEY, MILLER & RAMBO mz M Nov. 23, 1965 L. MARTIN METAL CLAPBOARD SIDING FOR BUILDINGS 2 Sheets-Sheet 2 Filed Dec. 31, 1962 INVENTOR.

MART l N IZOUIS MAHONEY, MILLER SRAMBO WMeW/ML United States Patent 3,218,772 METAL CLAPBGARD SIDING FOR BUILDINGS Louis Martin, Columbus, Ohio, assignor to Rollon Corporation, (lolumbus, Ohio, a corporation of Ohio Filed Dec. 31, 1962, Ser. No. 248,401 8 Claims. (Cl. 52-508) My invention relates to metal clapboard siding for buildings and is a continuation-in-part of my application Serial No. 222,543 filed September 10, 1962, and now abandoned. It has to do, more particularly, with metal clapboard siding for buildings in the form of elongated siding strips adapted to be horizontally disposed in cooperation with attaching strips secured to the building and with which the respective upper and lower edges of the siding strips interlock. According to my invention, each siding strip and the associated attaching strips are made of sheet metal, preferably aluminum, of novel crosssectional form to permit a novel manner of application resulting in a surface covering which is completely watertight as well as pleasing in appearance, especially in that each applied siding strip is free of all waves, ripples and distortions which would detract from its appearance.

The present invention is directed mainly to the combination of siding strips or panels and associated attaching strips. The attaching strips are nailed to the building in vertically spaced horizontal relationship and the siding panels interlock therewith both at the top and the bottom edges of the panel. No nails or staples extend through the panels for securing them to the building. The edges of the panels interlock with the associated upper and lower attaching strips so that any panel, if damaged, can be removed and replaced without disturbing any panel above or below it. The arrangement of attaching strips and associated interlocking panels according to this invention simplifies application of the siding and assures perfect alignment and the application can be by unskilled labor. In addition, according to this invention, the attaching strips and the panels are so designed that when the strips are properly applied and the panels are interlocked therewith, a bending force is created at the upper and lower edge of each panel which causes an outward bowing of the panel relative to the building surface. This bowing removes or erases all ripples, waves and distortions which might be created in the surface of the panel in forming or handling the strip. This outward bowing creates a convex surface which is very pleasing in appearance, and causes the siding to stand out aesthetically to a greater degree than the usual straight siding panel. Furthermore, the outward bowing of the panel facilitates the removal of the panel if that ever becomes necessary.

Various other objects and advantages will be apparent from the drawings and the following description.

In the accompanying drawings, I have illustrated an example of my invention but it is to be understood that variations thereof may be made without departing from the basic principles of my invention.

In the drawings:

FIGURE 1 is a perspective view of a fragment of a wall structure to which the siding of my invention has been applied.

FIGURE 2 is an enlarged vertical sectional view taken along line 2-2 of FIGURE 1 showing one panel of siding and the associated attaching strips at its upper and lower edges.

FIGURE 3 is a perspective view of a portion of one of the siding panels.

FIGURE 4 is a perspective view of a portion of one of the attaching strips.

FIGURE 5 is an enlarged sectional detail showing the cross-sectional shape of the attaching strip and the associated interlocking lower edge of an adjacent upper panel and the associated interfitting upper edge of an adjacent lower panel.

FIGURE 6 is a vertical sectional view similar to FIG- URE 2 but showing how one of the panels can have its lower edge lifted off the associated upper edge of the adjacent lower attaching strip to permit removal and replacement of the panel.

In general, as indicated in the drawings, I provide a siding strip 10 and cooperating attaching strips 11. These members cooperate and interfit with each other. The attaching strips are adapted to be nailed, stapled or otherwise attached to the building surface and the siding strips are adapted to be mounted on the associated strips so as to be held on the building without passing nails or staples through the siding.

The siding strip comprises a main body or panel 12 which has at its upper longitudinal margin a continuous curved lip 13 of hook-form which extends rearwardly from the plane of the panel. At the lower longitudinal margin of the panel there is an inverted U-shape channel formation 14- behind the plane of the panel which is attached thereto by an attaching flange 15 which extends rearwardly or inwardly from the lower margin of the panel and is at an acute angle relative thereto. This flange 15 connects to the outer or forward leg of the channel portion 14 which extends downwardly to a greater extent at the point indicated at 14a than the inner or rear leg which terminates at the point 141). It will be noted that the hook 13 is of a width forwardly and rearwardly of the panel 12 which is slightly less than the corresponding dimension of the inverted U-shaped channel 14. The attaching flange 15 extending between the inverted channel 14 and the panel 12 is of selected extent to space the lower margin of the panel outwardly from the building surface a distance sufliciently greater than the spacing of the upper panel margin from the building surface to cant the panel outwardly from top to bottom edges to give it a clapboard effect.

The strip 11 may be of suitable cross-sectional form to include a flat Wall-surface contacting body section 17 which is adapted to be nailed or stapled flat to that surface. This body section has at its upper edge a hook-receiving curved lip 18 which is turned outwardly. This portion 18 is spaced outwardly from the body section 17 by means of an attaching angular bend 19. Thus, the hook-receiving portion 18 will be spaced outwardly from the building surface when the body section 17 is in flat contact therewith. It will be noted from FIGURE 5 that the hook or curve of the portion 18 is relatively shallow as compared to the hook 13 which is to be inserted upwardly therewithin and as compared to the deep inverted channel portion 14 which is adapted to the slipped over the portion 18. The portion 18 is at its lower side complemental to the hook 13 so as to snugly receive it and at its upper side is complemental to the channel portion 14 so that it will fit snugly thereover.

According to this invention, the siding may be applied from the top down or the bottom up on the building surface or wall as desired. In applying the siding, one of the securing or attaching strips 11 is first nailed to the building surface in the position indicated in FIGURE 5. Then the next securing strip 11 is nailed to the building surface in vertically spaced relationship to the first strip and in parallel relationship thereto. It is a simple matter to nail the strips to the surface and to level them and space them vertically properly. This can be done by unskilled labor. The adjacent strips are spaced vertically a predetermined distance so that when the siding is mounted thereon, the panel thereof is bowed as indicated in full lines in FIGURE 2. The normal unbowed condition of this panel is illustrated by dotted lines in this figure. The spacing of the strips is such that the vertical distance between the hook-receiving lip portions 13 of the twoadjacent strips is less than the normal, distance between the hook 13 and hook-receiving channel portion 14 of the panel which is to be mounted thereon. Thus, to slip the hook 13 into the portion 13 of the upper attaching strip and then to slip the channel portion 14 over the portion 18 of the lower attaching strip requires a slight outward bowing of the panel 12 which gives the desire-d convex effect and eliminates all ripples, waves, distortions, etc.

The application of the siding continues merely by securing additional attaching strips 11 to the building surface in proper vertically spaced relationship, inserting the hook 13 of each successive siding strip back under the hookreceiving portion 18 of the adjacent upper attaching strip 11, and bowing the panel 12 of that siding strip to permit hooking of the lower edge 14 thereof on the portion 18 of the adjacent lower attaching strip 11.

Anytime it is necessary to remove one of the siding strips, this can be done, as indicated in FIGURE 6, by pressing upwardly with the fingers on the connecting flange 15 of that strip to how the panel 12 sufficiently to release the bottom edge of that panel from the associated lower attaching strip. Then the upper edge of the siding panel can he slipped downwardly from the cooperating upper attaching strip. It will be noted that the portion 18 is relatively shallow to facilitate removal of the hook portion 13. The hook 13 is not as shallow as the portion 18 but both are much more shallow than the inverted channel portion 14.

It will be apparent that this inventiton provides a combination of siding strips and attaching or securing strips which make it possible for unskilled labor to accurately apply the panels. It is not necessary to pass nails or staples through the siding strip itself. Any panel, if damaged, may, therefore, be removed and be replaced without disturbing any panel above or below the one being removed. Furthermore, panels can be removed readily for inspection purposes such as to check on whether or not there are termites, etc. in the underlying wall surface. Due to the cross-sectional shape of the panel edges and the associated securing strip edges with which they interlock, in the application of the siding, perfect alignment can be obtained with ease and with unskilled labor.

Various other advantages will be apparent.
