whichis particularly advantageous ingcovering old shingled roofs in a manner to j I produce a very smooth finish;

Another object is to provide a roof construction in which the composition shingles very closelyimitate a tile roof. V "A further object is to provide a plurality of shingles which are so constructed that they may be laid over an old roof having an irregular edge and yet laid in perfectly straight lines and caused to match perfectly without the least dificulty.

Another object is to provide a shingle in a roof construction of the above character, the shingle being-of simple, durable and inexpensive construction. I

lViih theseand other objects in View, my invention consists in the construction, arrangement and combination of. the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fullyset forth, pointed out in my claim, and illustrated in the accompanying drawings, in which:

Fig. l is a perspective View of a roof embodying my invention.

Fig. 2 is a plan view of the base shingleemployed in my roof construction.

Fig; 3 is a sectional view through the same.

F ig. 4 is a. plan view of the base shingle and the end shingle illustrating the second step in the process of laying.

Fig. 5 is a plan view illustrating the third step in the processof laying.

- Fig. 6 is a sectional view through a roof constructed with my roofing.

Fig. 7 is a sectional view through one type of new roofing embodying my invention and Fig. 8 is a similar view of a somewhat modified form of new roofing.

In Fig. 1 I have used the reference character 10 to indicate an old weather beaten cedar shingle roof. The drawing indicates the edges of the roof as being broken and irregular.

It is practically impossible to recover such a roof with wooden shingles and it has been 1930. Serial 1%.. 469,385.

customary to cover roofs of this type with composition roofing or shingles. My invention comprises the particular construction of a plurality of shingles which may be matched up in perfectly straight lines and entirely obscure from view the old shingles.

The base shingle of my invention is indicated'generally by the reference character A and comprises a sheet 11 of composition material bent over to provide a side flange 12 and reinforced by a sheet metal plate 13 having the side flange 14 and the hook 15 which clamps the edge of the side flange 12.

The'hook 15 secures the reinforcing plate to the shingle. No other securing means is necessary. The reinforcing plate serves to hold the flange 12'rigidly in a position at right angles to the body of the shingle 11.

It will be noticed that the side flange on the base shingle Ais-formed on the side.

The end shingle B has an end flange 16 which is identical 'in construction to the side flange 12. The v reinforcing plate for the flange 16 is indicated by the same numerals as forthe'flange 12." The endshingle B is provided with the usual projecting portions. 17 separated by slots 18 extending substantially half the width of the shingle. Attention is called "to the fact that the end flange 16 extends the full width of the shingle. I

The filler shingle C does not have a flange ofany kind. ."It'is a flat shingle provided with projecting portions 19 which are the same shape as' the projecting portions 17. These projecting portions are of a common symmetrical shape, the preferable shape being semi-hexagonal so that the lower edge of one ofthe projectingportions19 will exactlyfit the upper edge of one of the recesses 18 and so'that the lower edges of the projecting portion 17 will fit the recesses in the filler shingles C. p I r The end'shingles B and the filler shingles C which are positionedat the end of the roofing have the lengths which are proper tionate to the length of a fullshingle about as shown in Fig. 5. The filler shingles C are providedin full length equal to the length of the base shingle'A=which is a full length shingle.

In laying the roof, the base shingles A are first laid end to end with their side flanges resting against the lower edge of the root. In this manner the shingles will be laid in a straight line the irregularities in the old roof edge being too closely spaced to cause a divergence.

The base shingle A is positioned with its end edge flush with the side edge of the roof. One of the end shingles B is then laid on top of the base shingle as shown in Fig. 4 and is moved to a position where the lower edges of the projecting portions 17 are flush with the outer surface of the flange 12.

The flange 16 will then completely cover the space at the end of the base shingle, the corners of the two shingles coming together. The drawing is somewhat exaggerated in this respect, the corners being indicated slightly spread apart in order to better illustrate the construction of the shingles and to make the drawing more clear.

'The lower extremities of the projecting portion 17 being exactly flush with. the flange 12, the second shingle will be laid parallel with the first.

One of the filler shingles C is then laced in position as shown in Fig. 5 with the lower edge of the projecting portion 19 exactly coinciding with the upper edge of the space 18. Other filler shingles are laid in line with the end shingle B and the first filler shingle C. These will be full length filler shingles. This particular phase of the construction is old in root constructions and is not illustrated or described in detail. Another end shingle B is then laid upon the filler shingle C as shown in Fig. 1. The lower edges of the projecting portions 17 are lined up wit the upper edges of the recesses in the filler shingles. The flange 16 of the second end shingle overlaps the flange 16 of the first end shingle, thus producing on the edge of the root the effect of a tiled root. It will be understood that as each shingle is placed in position, it will be nailed through the portions which will be later covered by upper shingles.

The advantages of my roofing reside in the ease of application and the improved appearance after it has been laid. The construction responsible "for these advantages is the combination of a base shingle having a side flange and an end shingle having an end flange.

Figs. 7 and 8 are sectional views taken on horizontal lines parallel to the ridge pole of new roof constructions. The sheathing is shown in these figures at 20, the moulding at 21 and one of the end shingles at 22. The flange of the shingle is rested snugly against the edge of the sheathing.

It will be understood that instead ofconstructing the roofing in short sections as shown that the shingles may be constructed in long strips and shipped in rolls similar to ordinary roll roofing. Furthermore the in vention may be applied to old roofs, new roofs, barns, sheds, chicken houses and the like as well as dwelling structures. It may be used either on sloping roofs, gabled roofs or flat roofs.

The end shingles B can be used on the side of a house as well as on a root. In this case, the flanges 16 on one shingle are lapped under the body of the other shingle and the flanges of the other shingle are lapped over the body of the underneath shingle.

Some changes may be made in the construction and arrangement of the parts of my invention without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claim any modified forms of structure or use of mechanical equivalents, which may be reasonably included within its scope.

I claim as my invention:

A composition shingle comprising a flat body portion, a flange bent at right angles thereto and a sheet metal reinforcing plate comprising a portion resting flatly against the under surface of the body portion of the shingle, a flange portion resting snugly against the inner side of the flange portion of the shingle and a channel portion formed as the termination of said flange portion receiving and clamped upon the flange portion of the reinforcing member.

Signed this 2nd day of July, 1930, in the county of WVoodbury and State of Iowa.
