and particularly to a shinglewhic may be made of sheet metal, or like material, stampred, or pressed, into suitable shape so that the shingle when applied will'so cooperate with each other as to efl'ectivelyshed water.

A further object is to so design the shingles so that the greater portion of their extent will rest flat upon the roof, thus permitting the roof to be freely walked upon without likelihood of injury to an of the seams, or joints, or without likelihood of interfering with its water shedding properties.

A further object is to provide retainin means for the shingles of a character sac that portions of the shingles which are exposed to the weather will be firmly and securely held against any tendency to lift away from the roof and to accomplish this result without necessity for driving nails,

. staples, or other devices, through said portions of the shingles.

A further object 18 to so shape the shingles as to fully provide for all expansion an contraction after the shingles have been laid.

Other objects and aims of the invention, more or less specific than those referred to above, will be in part obvious and 1n part pointed out in the course of the following description of the elements, combinations, arrangements of parts and applications of principles, constituting the invention, and the scope of protection contemplated w1ll be indicated in the appended claims.

In the accompanying drawings which are to be taken as a part of this specification, and in which I have shown merely a preferred form of embodiment of the invent1on:-

Figure 1 is a top plan view of a roof showing a lurahty of the improved shingles applied thereonto, and with one shingle illustrated in the act of being moved into position.

Figure 2 1s an enlarged detail plan view 5 of a portion of one of the shingles-illustrating the details thereof and showing the improved retaining device.

Figure 3 is an enlarged transverse sectional view taken substantially upon the plane ofline III of Fig. 1, for illustrating the details of the joint and the manner in which the retaining device operates.

Figure 4 is an enlarged detail sectional view taken substantially upon the plane of line IV of Fig. 1 for illustrating the manner in which the shingles are attached to the edge of the roof, and

Figu one of the retaining devices.

Referring to the drawings for describing in detail the structure which is therein illustrated, the reference character L indicates .Fig. 1, represented by the reference character G. This shingle consists of a single mtegral rectangular piece of sheet metal, or other ap ropriate material, pressed, or

stamped, into shape by suitable machinery so that 1ts u per surface is made to represent alura ity of smaller shingles, as 1, 2, 3 an 4. Extending along the two lower marginal edges are raised beads 5 and along the two upper marginal edges are raised beads 6. -When the shingles are assembled to cover a roof, as shown at the right hand (1 side of Fig. 1, the heads 5 of one shingle overlap the heads 6 of two previously applied shingles. Accordingly the beads 5 are made sufficiently larger than the beads 6 so that they will nest together in the manner as clearly seen inFig. 3.

The shingles are laid in a diagonal position, and the nested, or interengaging, beads 5 and 6 o erate to efi'ectually prevent an passage 0 rain water, or the like, throng the joint, and particular note is here made that the beads are continued across the upper and lower corners of the shingles.

The relative size of beads 5 and 6 is important with relation to the expansion and re 5 is a detail perspective view of i contraction of the shingles under the effects are open spaces, as 8 and 9, at opposite sides of bead 6, which spaces will permit of a sufficient movement so that there will be no tendency of the shingles either to buckle, or to tear away from each other under changing temperatures.

In this connection also it should be noted that in shaping the sheet metal to represent the

shingles

1, 2, 3 and 4, intersecting raised beads, as 10, are formed which are substantially the same as the beads 5, and that these beads 10, being formed as are the beads 5 and 6 by-bending up the material of the sheet, naturally provide for a certain amount of elasticity in the sheet such that expansion and contraction of the sheet may take place without injury even though for any reason the lost motion provided in the spaces 8 and 9 is not suflicient.

The retaining devices H employed are clearly seen in Fig. 5. These are formed from sheet metal stamped into shape for providing an upwardly projecting rib 12 and a corresponding downwardly facing oove 13, and for providing a marginal ange 14.. A plurality of stiffening ribs 15 extend transversally across the rib 12 and to oppositesides of said rib 12 along the flat portion 16 which is designed to rest upon the flat adjacent surface portion of the shingle.

The beads 6 in each shingle are formed with one or more portions 17 of reduced cross section, said portions being of a size to fit and be received snugly within the groove 13.

When a shingle has been moved'to position upon the roof a retaining device H is applied over each of the reduced portions 17 and is fastened in position by means of one or more nails, screws, or like devices, 18 which extend therethrough and through the underlying material of the shingle and into the roofing boards. The nails 18 are applied as close as possible to the rib 12 and in position between ribs 15, suitable openings, as 19, being preferably formed through the flat portion 16 of the retaining device for this purpose.

The ribs 15 serve a double purpose;- first, of so strengthening the retaining device that the edge portion thereof, carryingthe flange v 14, is made sufliciently rigid with the portion thereof held by the nails 18, that said nails will serve to hold the portion carrying flange 14 against bending, or lifting, upwardly away from the roof at any time; and second,

to collectively provide a suitable support-- abrupt incline.

14, adjacent the edges 21, are folded over said edges 21, as best seen in Fig; 3, and the operation is complete.

By arranging the shingles diagonally, that is so that their lower edge portions extend diagonally relative to the slant of the roof,

and by placing the retaining devices in such osition as to en a e said dia onall .dis-

posed edges, the formation of'pockets is,

avoided and an efficient watershed thereby provided at the retaining devices.

The opposite side corners of each shingle are preferably cut ofi, as at 22, so as to avoid multiple thickness of metal where adjacent shingles meet. The joints thus formed are, of course, covered by the lower corner portion, as 23, of overlying shingles, as will be clearly apparent from inspection of Fig. 1.

In order to give the maximum water shedding properties to the heads 5 and 6, it is preferable that said beads be shaped with their upper sides, as 24, of gradual incline, whereas the lower sides, as 25, are of a more The gradual incline on the upper side of heads 5 provides a surface by which water may flow uninterruptedly over the beads even though the roof be only of slight incline. The corresponding shape of the upper-side of beads 6 provides reinforcing and supporting means for the overlying portions of beads 5. The steeper incline of the lower sides of beads 6 forms a more perpendicular wall opposing passage of any water upwardly through the joint between the two shingles. And the steeper incline of the lower sides of beads 5 provides definitely defined lines upon the finished roof for denoting the contour of the shingles.

At the eaves of the roof shingles, as 26, are employed which may be conveniently referred to as starter shingles. These are the same as those already described except that their lower halves have been omitted and in their. stead the lower edge of the shingle is formed with a bead 27 extending from one side corner to the other of the shingle and adapted to project downwardly over the'edge poition, as 28, of the eaves. Below the head 27 is preferably provided a flat-portion 29 adapted to receive nails, or the like, 30 by means of which the lower edges of the shingles may be held in position.

The heads 27, in addition to being ornamental, provide. for easy expansion and contraction of the roof portion, as 31, of the shingle- In laying a roof there is first applied a number of starter shingles corner to corner along the caves of the roof, each being held along its upper edges by its proper quota of retaining devices H and along its lower edge by nails, or the like, as 30. After these starter shingles have been applied then the regular full size shingles are placed in position one after the other, as has been already described, each having its upper edges held by a proper number of retaining devices, and having its lower edges held by flanges 14 of previously laid retaining devices.

As many changes could-be made in this construction without departing from the scope of the invention as defined in the following claims, it is intended that all matter contained in the above description, or shown in the accompanying drawings, shall be interpreted as illustrative only and not in a limiting sense.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A roofing shingle of rectangular shape and bein made from sheet material pressed to provide beads extending along the margins of-the shingle, the shingle being adapted to be laid diagonally upon a roof, the beads which extend alon the lower marginal edges being relative y larger than the beads which extendalong the upper marginal edges so that the lower beads of each shingle will fit over and receive the upper beads of previously laid shingles, and means for engaging and retaining the four edges of each shingle in said position.

2.
