SHINGLE Filed May 3, 1937 Inventor 3. (ffi'arrzyan w By Jmww m',

A orneys Patented Sept. 21, 1937 STTE- TNT CFFIQE 2 Claims.

My inventionrelates to improvements in roofing shingles. of the type disclosed in my co-pending application, Serial No. 71,946, filed March 31, 1936, and over which the present invention is 5 designed as an improvement.

In my co-pending application, above designated, I have disclosed a sheet metal roofing single of the diamond-shaped type designed to be laid cornerwise in interlocking relation with subj acent shingles.

The principal object of my present invention is to provide a shingle of the general type disclosed in my application, supra, but equipped with improved means for interlocking with other Singles, the improvements being directed toward accomplishing the interlocking by relative camming of interlocking parts of the shingles into looking relation.

Another object is to provide a shingle of the type above identified, adapted to interlock with other shingles in clamping relation thereto and against relative Vertical movement.

Other and subordinate objects are also comprehended by my invention, all of which, together with the exact nature of my improvement, will be readily understood when the following description and claims are read with reference to the drawing accompanying and forming part of this specification.

In said drawng:

Figure 1 is a fragmentary view in top plan illustrating the manner in which the shingle of my invention is laid,

Figure 2 is a similar view, drawn to an enlarged scale, and illustrating in detail the relation of one shingle to subjacent shingles,

Figure 3 is another fragmentary view in top plan illustrating the corner construction of the shingle, and an interlocking slot with which the shingle is provided,

Figure 4 is a view in transverse section taken on the line 4-4 of Figure 1, looking in the direction indicated by the arrows and drawn to an enlarged scale,

Figure 5 is a fragmentary view in edge elevation of the shingle, and,

Figure 6 is a view in top plan of the shingle.

Referring to the drawing by numerals, the

' shingle I of my present invention, as in the case metal, substantially diamond-shaped, and designed to be laid cornerwise to provide upper and lower pairs of side edges 2 and 3, respectively, convergent in each instance, and top, bottom and side corners 4, 5 and 6, respectively, the latter being straight vertically. The upper side edges' are each provided with an upturned right angled marginal fiange l, and the lower side edges with a similar down-turned fiange 8 respectively.

Extending along the fianges l parallel therewith are two courses of parallel strengthening and water deflecting ribs 8 punched upwardly in the shingle i and intersecting the side corner 6 all as shown in Figure l.

Coming now to the interlocking feature, the bottom corner 5 of the shingle is formed with a normally depending bendable V-shaped looking tab iii formed by bending said corner downwardly. A pair of'slots i i are formed in the side edges 3 of the shingle, respectively, immediately below the side corners 6, said slots extending inwardly of said edges parallel with the transverse median line of the shingle. A pair of slots |2 formed in the side flanges 8, respectively, extending rearwardly and upwardly from the edges of said fianges to the outer ends of the slots II, and forming oblique camming continuations of the latter.

As will be clear from an inspection of Figures 2 and 3, particularly, the shingles are laid in transverse overlapping rows with the Corners 6 of contiguous shingles in a row abutting and the fianges 'l of one row overlapping the upper edges of the shingles in a subjacent row below the lowei` course of ribs 9 to cover the latter from view. In this position, the slots Ii in adjacent shingles I of each row are horizontally aligned in mating relation with the mouths of the Slots l2 opening onto the lower shingles just below the inner course of ribs 9 of a subjacent shingle, which ribs form a right-angled abutment below and in front, or above, said slots |2.

The tab iU of a shingle is adapted to interlock in the mating slots and |2 of a pair of subjacent shingles as follows. The tab Ii] is inserted into said mating slots ll and the shingle pressed downwardly at that point. Under such pressure said tab is bent and cammed forwardly under the subjacent pair of shingles first by the oblique slot |2 and second by engagement of the point of the tab with the before-mentioned rightangled abutment formed by the lower course of ribs 9 on a shingle subjacent to said pair. As best shown in Figure 4, said abutment cams the end of the tab IO upwardly thereby interlocking r the shingle from which said tab depends with the shingles of the subjacent pair. It will be observed that the described interlocking relation clamps the interlocked shingles together against Vertical movement.

ly, the latter being vertically straight,` 'and having a pair of slots extending inwardly thereof, re-

spectively, a pair of downturned marginal flanges extending along said lower sideedges, respectively, and having a pair of inwardly extending slots therein, respectively, inclining from the outer ends of the slots of said first-mentioned pair 'and forming continuations thereof, and a downturned bendable tab on the lower corner of said shingle.

2. A metal roofing shingle comprising a diamond-shaped body portion having upper and lower pairs of convergent side edges, respectively, and upper, lower and side Corners, respectively, the latter being vertically straight and having a pair of slots extending inwardly thereof, respectively, a pair of downturned marginal fianges extending along said lower side edges, respectively, and having a pair of inwardly extending slots therein inclining from the outer ends of the slots of said first mentioned pair, respectively, and forming continuations thereof, a downturned bendable tab on the lower corner of said shingle, and a pair of upstanding convergent beads extending along the upper side edges, respectively, parallel therewith and intersecting said side Corners.
