GEORGE B. WEAST, OF NEWVILLE, PENNSYLVANIA.

SHEET-METAL ROOF.

EiPIElCIPICATION forming part of Letters Patent No. 329,789, dated November 3, 1885.

Application filed December 18, 1884. Serial No. 150,649. (No model.)

To aZZ whom it may concern:

Be it known that I, GEORGE B. WEAST, residing at Newville, in the county of Cumberland and State of Pennsylvania, have invented a Sheet-Metal Roof, of which the following is a specification.

The invention will first be described inconnection with the drawings, and then pointed out in the claim.

Figure 1 of the drawings is a view showing my invention as appied. Fig. 2 is a crosssection through line 00 5c of Fig. 1. Fig. 3 is a plan view of the shingle, showing its construction on the upper face. Fig. 4'is a transverse section of the roof and cap.

In the drawings, A represents my metallic shingle made of sheet-tin, and B is a sheathing or roof-frame, to the transverse pieces I) of which the shingles are nailed at diagonallyopposite corners.

*1 preferably make my shingle'in an approximately rectangular form, although the shape may be greatly varied without departing from the principle of my invention.

A represents the roof-cap. It will thus be perceived that the fastening-nails are in a diagonal line at right .angles to the pitch or inclination of the roof, while the complementary angles of the rectangle will be bisected by a line drawn in the-same direction as the pitch. In this line of bisection I make the groove a, and on each side thereof the branch grooves a, inclined thereto and terminating therein.

By this construction a series of water-channels are provided, so as to gather the water and guide it off the shingle and finally into the eaves-trough. I prefer to make these grooves 11 a by corrugating the metal, so as to make them more rigid and less liable to be bent by wind or other force. On two opposite sides of the shingle I make the subjacent folds a a and on the other two sides the superposed folds at a said folds a a forming hooks which interlock and unify the roof, as if all its parts were integral. The shingles are thus made to cooperate in resisting wind, rain, or storm,

and the roof is a very permanent one, little liable to get out of order. Of course, like every other metallic roof, this should be well painted to prevent oxidation.

I am aware that the grip-lock is not new, and that grooves have been used in sheet-metal shingles; but I know of none in which my long pitch-groove a, with all the branch grooves opening into it, has been employed; hence What I claim, and desire to protect by Letters Patent, is-

A metallic shingle having the long groove a running from top to bottom with the pitch of the roof and all the oblique branches a opening thereinto, as shown and described.
