SHEET-METAL SHINGLE.

SPECIFICATION forming part of Letters Patent No. 409,387, dated August 20, 1889. Application filed April 8, 1889 Serial No. 306,298. (No model.)

ToaZZ whom it may concern:

Be itknown that we, TILLIAM JOHN BROWN, mechanic, and JOHN ONIONS THORN, bookkeeper, both of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have jointly invented a certain new and Improved Sheet-Metal Shingle, of which thefollowing is a specification.

The objectof the invention is to design a sheet-metal shingle which will be easily secured to the roof with protected joints, and a series of which is specially adapted to form a valley; and it consists, essentially, of a series of metal shingles bent angularly to form a valley, the bottom edge of each shingle overlapping the top edge of the shingle below it, and the sides of each shingle being crimped to form an angular overhanging wall on each side of the valley, and on the outside of each wall a gutter with a nailing-edge extending beyond it, the inner wall of the said gutter being bent inwardly to form a recess into which the straight edge of the adjoining shingle may fit to form a cap for the gutter and the nailingedge, substantially as hereinafter more particularly explained.

Figure 1 is aview of a roof showing the application of our improved shingle and valley. Fig. 2 is a sectional plan through a: y. Fig. 3 is an enlarged edge view of the shingle, having a nailing-edge on one side only.

As our shingle is specially invented and adapted for the formation of a valley with a water-tight joint, we shall first explain its application for this purpose and will draw attention to Fig. 1. In this figure it will be noticed that the shingles A are bent angularly to form the valley, and we may mention here that the bottom of each shingle overlaps the top edge of the shingle below it, so as to pre vent any water passing through the joint. It will be observed that the sides of the shingles are crimped, the angular overhanging wall a being formed on each side of the valley, so as to prevent the water in the valley fromflushing over its sides. From this angnlarlyformed wall the surface of the shingle extends a short distance, and is then bent downwardly and inwardly to form a recess l1, and is then bent back to form a gutter, the outer edge of which extends at substantially right angles to the bottom of the gutter to a point about level with the flat surface of the shingle. The edge of the shingle is then bent down to form a nailing-edge (Z. The recess 1) is intended to receive the straight edge of the adjoining shingle, which forms a cap forthe gutter and for the nailingedge.

A shingle shaped as described not only forms a very effective covering, the sections of which may be readily secured and hermetically connected, but they are specially adapted to form a superior valley.

Vhat we claim as our invention is 1. A metal shingle having one side crimped to term a gutter with a nailing-edge extending beyond it, the inner wall of the said gutter bein bent inwardly to form a recess, into which the straight edge of the adjoining shingle may tit to form a cap for the gutter and for the nailing-edge, and an angular overhanging wall, substantially as and for the purpose specified.

2. A series of metal shingles bent angularly to form a valley, the bottom of each shingle overlapping the top edge of the shingle below it, and the sides of each shingle being crimped to form an angular overhanging wall on each side of the valley, and on the outside of each wall a gutter with a nailing-edge extending beyond it, the inner wall of the said gutter being bent-inwardly to form a recess, into which the straight edge of the adjoining shingle may fit to form a cap for the gutter and for the nailing-edge, substantially as and for the purpose specified.

Toronto, March 25, 1889.
