NASHVILLE, TENNESSEE.

M ETALLIC ROOOFINQ-PLATE.

SPECIFICATION forming part of Letters Patent No. 354,484, dated December 14, 1886.

' Application tiled November 17,1885. Serial No. 183,133. (No model.)

My invention refers to the construction of` the lateral edges of metallic roong-plates,

1o whereby the plates are readily attached to the roof and a water-tight connection formed between adjacent plates in a manner which admits of the contraction and expansion of the material.

Its nature consists in constructing the roofing-plate with one lateral edge doubled toward a groove which receives the edge of the adjacent plate, the doubled edge acting as a spring to hold the edge of the adjacent plate, and forming a water-tight seam, as will be hereinafter set forth. l

In the annexed drawings, forming part of this specification, Figure l is a perspective view of the rooiingplate, and Fig. 2 is a crosssection of joint between adjacent plates.

The saine letters of reference denote the same parts in both the gures.

The plate P has near its right side an outward projection, c, which forms a recess between it and the plate-surface for the reception of the opposite edge of the next adjacent plate. Beyond this recess the edge of the plate is doubled over, as shown at f, so that the free edge ot' this doubled part will forni a 35 spring, a, rising a little above the outward projection c. The doubled edge f has perfo rations for the nails which fasten the plate to the roof. The opposite edge of the plate has a raised flange, d,with a shoulder, b, the depth 4o that the projection c is above the plate-surface.

To use these plates the left-hand edge of the first plate is turned down and nailed to the edge of the sheeting. Nails through the perforations in the double edge f complete the fastening of this plate to the roof. The edge of the iiange d of the next plate is then inserted into the recess i of the n'rst plate, and after the plate is pushed to the extent of the recess this second plate is nailed down through the perforations in' its doubled flange f. The 5o spring a'of the first plate presses against the under surface of the ange d and holds the flange np against the top of the recess. The depth of the shoulder b admits of the plate resting flat upon the root" after the joint is formed. The space between the spring a and the plate forms a conduit for any water that might pass between the flange d and the projection c, the doubled edge f preventing its passage to the sheeting. The seam thus formed 6o between adjacent plates is water-tight, and at the same time admits of the contraction and expansion of the metal under the different condi tions of temperature to which it is exposed.

Vhat I claim as new and of my own invend5 tion, and desire to secure by Letters Patent, 1s-

1. A metallic rooing-plate having one edge doubled toward a groove which receives the edge of the adjacent plate, the doubled edge `7o acting as -a spring to hold the edge of the adjacent plate, and forming a water-tight seam, substantially as shown and described.

2. A metallic roofing plate formed at one edge with the raised iange d and shoulder b, and at the opposite edge with the outward proj cction c, forming a recess, i, and the doubled edge f, forming the spring a, substantially as described.
