METALLIC' SHINGLE.

Specification of Letters Patent.

PatentedMay14, 1912.

Application filed July 5, 1910. Serial No. 570,264.

stood from the following description taken in connection with the accompanying drawing in which Figure 1 is a face view of a shingle, of generally square outline, embodying my im- 'provements: Fig. 2 a number of the shin-- gles, properly assembled: Fig. 3 a face view of the sheet, cut to pattern, and ready for certain edge bendings to form the complete shmgle: Fig. 4 a vertical seetlon through the upper tab: and Fig. 5 a face view of the improved shingle when modified in outline form, as compared with the other figures, being diamond-shaped.

The various figures of the drawing exhibit some diversity of scale.

In the drawing :1, in Fig. 3, indicates the flat plate, cutto pattern, substantially square in outline: 2, the lower let'thand edge of the plate: 3, the lower right-hand 5 edge: 4, the upper right and left-hand edges: 5, a. tab at the left-hand corner of the plate, forn'ied by notching the plate, as shown, the tab projecting diagonally upward, parallel with edge 2 and as far as up- 4 per left hand edge 4: 6, a similar tab at the right-hand corner of the plate: 7, a tab projecting from the top corner of the plate and formed by notching the plate. the upper extremities of this tab being in the lines of prolongations of the edges 4 of the plate: 8, a dam across the foot of top tab 7 and formed by so indenting the back of the plate as to throw upward from the face of the plate a ridge having a length equal to tab 7: 9, the main body of the plate: 10. a booking flange extending along below the lower right-hand edge of the shingle, this hook being formed by bending the portion 3 of the blank under and inwardly, but not so close up to the body as to prevent a hooklower left-hand edge of the shingle, and

formed by turning under edge 2 of the blank: 12, the cut away lower corner of the blank to prevent the oi'erlappin of the contiguous ends of the hooking flhnges 10 and 11: 13, a hooking flange at the upper left- .hand corner of the shingle, formed by turning the upper left-hand edge 4 of the blank over onto the body: and 14, a similar hooking flange at the upper right-hand edge of the shingle, formed by turning the upper right-hand edge of the blank over onto the body.

In assembling the shingles on the roof, a shingle, disposed as in Fig. 1, may be secured by a nail at tab 7 and a nail at tab 6, these tabs being preferably punched for the nails. It is to be observed that all the tabs project out from the body of the shingle and not from the hooking flanges, this con-- struetion permitting of the upper portion of the shingle lying closely down to the roof.

Assume the shingle thus referred to to be the lower one seen in Fig. 2. A second shingle is now to have its hooking flange 10' hooked under the flange 13 of the first shingle, the tab 6 of the second shingle crossing the dam of the first shingle and projecting beyond the side of tab 7 of the first shingle, tab 6 of the second shingle is then to be nailed. This would constitute the lefthand shingle of Fig. 2. The third shingle is then to have its flange 11 hooked onto flange 14 of the first shingle, its lower corner covering the nailed tab (5 of the first shingle,

and the tab 5 of the third shingleoverlying the body and entering under flange 14; of the second shingle, the body of the third shingle overlying the nailed tab 6 of the second shingle, and so on over the entire roof, it being understood, of course, that in finishing out the edges of the roof half shingles will be employed, as is usual in metallic shingle work. Side tabs 5 and 6 are alike, in fact the shingles are entirely symmetrical and it follows that the laying of the shingles may be to the right or to the left, as is most convenient, and that one of tabs 5 or 6 will be nailed which comes into direct contact with the root' as distinguished from an overlying tab. In the manner of laying which has been described, and as is indicated in Fig. 2, the right-hand tabs 6 will be the nailed ones asthey come directly against the roof, while tabs 5 are overlying tabs.

It is to be observed that, as will be seen by reference to Fig. 3, the wastes from an original rectangular plate are but trifling. It will be further observed that the main body of the shingle at its upper portion may lay close to the roof and that the nailing tabs come down close to the roof, being projections from the bodyitself; and that nailed point-s are well housed so that leakage cannot occur at tabs 5 and 6 and that, furthermore, dam 8 prevents water being blown upward to tab 7. I

The improved shingles not only provide a roof of superior quality as to tightness, but they lend themselves to very economical con- "struction owing to smallness of Waste and to the fact that they are produceable from a flat plate at a single operation of a combined stamping and bending machine.

1. A metallic "shingle comprising, a rectangular body, overturned hooking flanges at the upper edges of the body, underturned hooking flanges at the lower edges of the body, tabs formed-by upward prolongations of the lower edges as the body beyond the upper edges of the body, a tab formed by 2. A shingle comprising a sheet metal I,

body having underturned edges on two ad'- jacent sides and overturned edges on the other two adjacent sides, the last named edges beingcut away at their meeting corner to accommodate a tile to be superposed, a convexdam being formed in the corner of saidtile between said overturned edges.

3. A roofing tile formed of sheet metal having underturnedlocking edges on two adjacent sides and having overturned locking edges on the other two adjacent sides, said overturned edges being cut away to leave a space at their meeting corner, the tile being'provided with a nailing tab extending from said corner, an outwardly convex dam being also provided-across said corner between said overturned flanges.
