SURFACE COVERING FOR BUILDINGS Filed Deo. 8, 1930 'Patented dune 14, 1932A noemer ruaonnnrc, or FRANKLIN, onto SURFACE COVERING- FOR BUELDINGS appncaaon mea. December e, raso. serial no. 500,806.

My invention relates to surface coverings 1 for buildings to render the sides and roofs thereof weatherproof, and includes among its objects and advantages an improvement especially useful in connection with that type of covering made up of continuous strips of dimensions materially greater horizontally than vertically.

l have illustrated the invention as applied if to the fabrication of a covering for the side walls of buildings of the type carrying surface ornamentation in imitation of ordinary Y bricks. ln order to complete the eect of real brickwork and give the appearance of l5 solid brick work at the corners, such strips should be applied so that at the meeting of two walls, one wall will appear to show theside portion of a brick adjacent the dihedral angle between the walls, while the other wall i" will appear to showh the end portion of the same brick. ln practice,- however, this has been dicult to achieve, because the strips on each wall tend to lie'in planes at a slight angle to the surface of the wall itself sloping downwardly and outwardly, and this incllnation or outward tilting of the portions of a strip that extends around the corner, tends to cause each portion of the strip to twist the other portion downwardly out of line with adjacent strips. When both portions are forced up into line, there is an excess of material at the corner, especially at the top of the strip, and this material gets in the way and causes unsightly bulging and deforma- 'tion of the outer surface of the corner.

In the accompanying drawing: l

Figure 1 is a plan of one form of covering element;

Figure 2 is a view similar to Figure 1 of the complementary form of covering element;

y Figure 3 is a fragmentary perspective of two adjoining walls, showing my improved covering elements applied thereto;

Figures 4 to 7 inclusive are edge views of covering elements showing various forms thereof. l

ln the embodiment selected to illustrate the invention, the covering element l0 comprises a simple Hat strip of composition mate- 5 rial, one side of which is finished withl an asphalt or tar surface. The other side, which faces outwardly in the finished structure, is provided with a coating of red grits vto form a colored band the thickness of an ordinary brick, and extending along the base of said covering element. Substantially the lower third Vof the element is red while the remainder is of a dark color.

The element l() is cut, or kerfed at 12, to leave a triangular notch in its upper edge. o0 The kerf 12 is so positioned relative to the ends of the covering element that when the element' is bent to form an L, the partsl and 16 thereof will be equal to the length and width of an ordinary brick respectively.- @e The kei-f 12 extends down from the upper edge of the element to a point just a little above the lower edge of the next overlapping element in the finished structure. If the kerf is cut before the strip is bent it will assist 7o in locating the line along lwhich bending should occur.

The element 10 is provided with a reinforcing member 18 in the nature of a thin flat band of sheet metal extendingv along the lower por- '35 tion of the element. The reinforcing member 18 has teeth 2() struck down therefrom and 4 embedded in the body of the. element when the tar is hot so as to be firmly united therewith. The extra strength thus provided more Se than compensates for the weakening of the element by cutting the kerf l2. y

The complementary element 26 illustrated lin Figure 2 has its kerf 28 positioned to the right of the middle of the element so that the portion 32 at the right is of the same length as the portion 16 at the left of the element 10 in Figure 1. Similarly the portion 30 at the left of the element 26 is of a length equal to the portion 14 of the element 10. The ele- 90 ment 26 is also provided with a reinforcing strip 34 identical with the strip 18.

An equal number of elements 10 and 26 suliice to form a complete covering for the immediate corner where two walls meet,

whether the dihedral angle is salient or reentrant.v For a salient angle allthe stripsare bent with theytar surface and reinforcing strips on the irfside of the angle, Aand for a re-entrant angle the side covered with grit is on the inside of theangle which will be the exposed portion of the finished wall.

The elements 10 and 26 at the corners project alternately dierent distances from the apex of the corner so that the vertical joints between their ends and the abutting straight strips constituting the body of the wall, will be mis-matched to form a waterproof covering. The strips extending across the fiat portions of the wall are arranged in rows 24 in alignment with the corner pieces.

Both the corner pieces and the straight strips are laid to expose all the red portion of each element and about a quarter of an inch of the dark colored portion above. The narrow dark strip thus exposed affords avery effective illusion of the plaster` or mortar joints between ordinary bricks.

That portion of each corner element just below the kerfs is of suficient'iexibility to permit the portions of the element on opposite sides of the angle to be twisted into good alignment by deformation of the material of the element at the corner, and the kerfs enable the covered portions of the element to move toward each other in the case of a salient angle, and away from each other in the case of a re-entrant angle.

In building up a salient angle, the element will be bent as in Figures l and 5, and in building up a re-entrant angle, the element will be bent as in Figures 6 and 7 All four forms may be made up from the two forms of fiat element illustrated in Figures l and 2 by simply bending them in opposite directions.

Without further elaboration, the foregoing will so fully explain my invention that others may, by applying knowledge current at the time of application, readily adapt the same for use under various conditions of service.

I claim:
