Application led February 20,- 1923. Serial No. 6209183.
While the commercial use of metal shin-l gles is increasing rapidly there are certain inherent deficiencies which prevent their use with the freedom in laying afforded' by wooden shingles. Two fundamental attributes of satisfactory shingling should beprovided for, to wit, a perfectly flat surface for all shingles in a row and flexibility in the order of laying successive rows and tiers without anyinterference in nailing. Metal Shingles heretofore known have satisfied many of the requirements such as Watertightness in the joints and butt edges for tightness but it has not been possible to lay l5 the shingles in any desired relationship and insure juxtaposed shingles presenting a contiiiuous uniform flat surface undisturbed by the joint line. Further, such shingles have presented the difficulty in nailing of overlapping strips and subsequent deformation from nailing.' l
It Ais the principal objectof the present invention to provide a metal shingle which shall embody all of the advantages of known shingles `and satisfy all ordinary requirements and shall, in addition, possess certain distinct improvements which facilitates the laying of the shingles rapidly in any desired .relationship andrtheirspacing and nailing without injuryor deformation and without destroying the continuous flat level surface provided by shingles in any given row. In'
accordance with the invention it is proposed to provide the improved shingles with a 95 tongue along one edge adapted to interengage with a groove along the other edge of a proximate shingle, and a nailing strip.
at the other end of peculiar form and disposition. This nailing strip is of such 40 length and shape as to provide a shoulder which is engaged with the upper edge of the shingle in the next lower tier and thereby automatically position the shingle being laid without, however, permitting the nailing strip to overliethe shingle in the next lower tier. The effect produced is to greatly facilitate the laying of the shingles and d theirproper spacing with respect to one i another and, of greatest importance, to permit the nailing of each shingle vwithout nailing through any other shingle and thereby deforming it or changing the general level of the surface line of'the shingles.
The invention will be4 described with u greater particularity hereinafter with reference to the detailed description of the illustrated .embodiment shown in the drawings, wherein:
Figure 1 is a view in plan of Ia metal shingle embodying the improvements.
Figure 2 is a view in section therethrough taken on the plane/indicated by the line 2-2 of Figure 1 and looking in the direction of the arrows.
Figure 3 is a view in front elevation 0f the improved shingle showing the relation of the nailing strip thereto.
Figure 4 is a view in planshowing three rows of shingles of improved form laid in staggered relationship.
Figure 5 is a schematic view in side elevation showing the overlapping relation of successive rows-of shingles. 1 1
Figure 6 is a fragmentary detail view in section showing the relation of the improved nailing strip to the tongue and groove joint whereby the surfaces of proximate shingles maintain the same plane.
The improved shingle a has formed therein a vertically extending channel b along its median line and a plurality of horizontally extending beads e adjacent its upper edge which assist' in forming a weather-tight joint between successive rows of shingles as willappear from Figure 5. Along one edge of the shingle. is stamped and formed a tongue a of preferably concave form while along the other edge is stamped and formed a groove a by bending a section of the metal reversely on itself. AitA this edge is also provided the improved nailing strip a.
In order to understand the improvements sought to be covered by the present applicaj tion the method of laying the shingles must be considered. These-shingles must be laid from left'to right and the rows thereof from bottom to top, as viewed in the drawings.
. In practice, it is desirable that metal shingles when laid shall have the appearance o f wooden shingles `and for this reason it 1s desirable to stagger them and so form them, as indicated' in Figure 1, as to have the appearance of two shingles. This effect vis secured bythe vertical groove b. Hereto-l fore, the problem has been to lay metalshingles in staggered relationshi necessitatin the nailing throng of two shingles an some disturbance of the smooth unbroken surface which should be presented without by juxtaposed shingles. In accordance with the present invention the nailing strip a is so formed as to rovide a shoulder a* at a predetermined d1stance from the lower edge of the shingle this distance being determined by the desired amount of overhang of the shingles in successive rows. In the illustrated embodiment, for instance, it is desirable that the vertical butt edge a formed atthe bottom of each shingle shall overlie the beads c, c, and to this end. the
shoulder a4 on the nailing strip a,s is so formed that when it abuts against the up er edge of the next lower shingle the butt e ge` a5 will be automatically positioned in proper relation to such lower shingle. The parts may be brought into this relation by a simple quick manipulation of the shingle by the workman and not only will the desired disposition beeffected in this manner but the nailing strip a3 will lie along the roof ready for direct .nailing without involving any of the other shingles. In this position the flat at the right edge of the shingle a and so forth for as man additional shingles and rows as are to be aid.
Changes in details of construction andrelation of parts may be made by one skilled in the art without departing from the scope of the invention as long as the advantages herein described are realized by equivalent mechanical means.
What I claim is: A. metal shingle having a lower butt edge to raise the shingle from the plane of a 'lower shin le, a uniform upper butt edge perpendicu ar to the plane of the shingle to permit stafrgering of the shingles in any desired relat1on', a nailing strip inclined downwardl from the plane of the raised shingle an havin a flat portion along its entire length resting on the sheathing to support the` side of the shingle evenly in such plane, a shoulder on the nailing strip to rest against the up er butt edge 4of the lower shingle to space t e respective shingles when in place, and 'a groove in the nailing strip to receive the edge of the adjacent shingle.
