y 1.937. D. F. FRADETTE 8 SHINGLE ELEMENT Filed March 12, 1956 LIE M 1N VENTOR.

J3 run-p F FRAIDETTE BY ,adzwwaw/ ATTORNEYS Patented July 1937 UNITED STATES PATENT OFFICE f The present invention relates to a shingl'eelement and is particularly concerned in the method of arching or bowing-a shingle element of thinshape because it is a contrivance of extraordinary simplicity. v

The shape of the element longitudinally and transverselyis such that when it is surmounted 20 'on the felt base and secured to place, the butt portion thereof is forced into intimate contact s with the base and the element below, so that accumulation of water, ice and snow therelmder at critical weather periods is practically eliminated.

, 25 The inherent'resiliency of the metal, andits tendency to return to its former preformed shape, contribute to the successful results herein set forth. In making the shingle element there'is given 30 to it the desired degree of curvature to impart to it the necessary compression,.so that when it is nailed to place it will be equally stressed, and will be maintained in substantial accurate and continuous engagement with the felt base and its contact surface with the element below.

The felt base used with the element is available on the market in various forms, therefore a description thereof is not given in full herein.-

The possibilities of application of the inven 40 tion are many for instance, the elements may be applied to side walls or the like, of various buildmgs. 1

Other objects and. features of novelty will appear from the description following hereinafter and from the claims.

For better understanding of this invention, reference is made to the accompanying drawing, which illustrates convenient constructionaliorms v of this invention .by way'of example only' and in 50 which:

Fig. 1 illustrates the shingle in perspective showing its formation. 4

! 2 illustrates another form of the shingle element in perspective.

55 3 illustrates in perspective, the element surmounted on felt bases, with a cushioning felt of ribbon configuration therebetween for the nail heads; the baseelement and the cushioning felt are shown in cross section.

v Fig. 4 illustrates in perspective, the element, 5 with bases shown in section associated therewith, the cushioning strip shown in Fig. 3 being eliminated.

Fig. 5 illustrates in perspective, the elements shown in Fig. 1 in association with base element, below and above in cross-section.

Fig. 6 illustrates perspectively an explanatory view showing the relation of the cushioning strip for nail-heads with the transverse aligningflange adapted to position the cushioning strip on the element. I

In the drawing likecharacters of reference designate similar parts.

' The shingle element, as a whole, of my invention is designated in 1 by the respective numbers 10, If and I2.

Between the portions II and H there is pro- I vided a transverse bend so that the portion H- extends slightly downwardly, giving the element longitudinally an, arch. Paralleling the bend-or bead l3 at the end of the portion l0 there is provided a reinforcing flange l2 integral with the portion II and is adapted to directly shield the edge of the felt base, and also to provide a suitable bearing and support for the end of the plate, and further tends to prevent buckling of the plate element, when the same is secured to astructure by suitable fasteningmeans such as

nails

20, 20, as shown in Fig. 6.

In Fig. 2 the plate element It is provided with a bead l5 having a cylindric exterior circumference It to give the element an arch,.otherwise the construction of the element is the same as that shown in Fig. 1.

In Fig. 3 the ribbon-like cushioning strip ll for the nail heads is shown between the base felt l8 on which the plate element It, shown fragmentarily, is mounted. r

In Fig. 4 the cushioning strip is eliminated, and the base I8 is shown stopping just behind the head l5.

' In-Fig. 5 the element shown in Fig. 1 is shown in assembled relation.

In Fig. 6 the elements are shown. in spaced relationship and showing a plate element H provided with an integrally formed transverse vertically extending rib or flange l9 paralleling the bead of semicylindrical configuration formed in the plate element. This flange is provided as an aligning and limitingmeaus so that the cushioning ribbon can be symmetrically interposed between the elements in making up the roof. The

nails

20, 20 are shown in position in the cushioning strip. It will be noted that the element is provided at its extremities with a transverse flange thus reinforcing the plate. The transverse bead also strengthens the plate transversely; besides it provides a means in the plate by which the plate may be given the proper arch form.

From the foregoing it should be apparent that the objects previously presented have been attained by means of the construction covered in the specification. v

While I have herein shown and described a preferred arrangement, it will be readily understood that changes and modifications therein may be found desirable or essential in meeting the various exigencies of use, and I desire to be understood as reserving the right to make any and all such changes or modifications as may be found desirable or essential, in so far as the same may fall within the spirit and scope of the invention as expressed in the accompanying claims when construed in the light of the prior art.

claim is:-

Having thus described my invention, what I longitudinal transverse bend therein and a transverse downwardly extending flange at an end thereof, a felt base below the element, a nailhead ribbon like cushioning strip,v an aligning flange therefor, the said strip abuttingthe transverse bend and positioned rearwardly thereof and confined between the bend and the aligning flange, nails in the nail-head cushioning strip, the transverse bend imparting suflicient resistance to'the element so that there will be simultaneously induced a counter force in the-element in opposition to exterior disturbing lifting forces.

2. A metallic shingle element having two angularly related plane portions formed by a bend extending transversely thereacross, one of the portions having a surface much greater than the other surface constituting the element, a ribbon like nail head cushioning strip surmounted on the lesser surface rearwardly of and in registry with the transverse bend, a felt base of conventional structure positioned below the shingle element; nails acting through said strip and said element to force the angularly related portions of the element-into substantial parallelismwith each other and with the cooperating base, thereby constraining the butt end ofthe element to resist exterior lifting forces.
