SPECIFICATIONforming part of Letters PatentNo. 239,104, dated March 22, 1881;

Applicationfiled January 20, 1881. (No model.)

Toall whom it may concern Be. it known that we, LORENZO LANE and LAURIN I).WOODWORTH,OitiZ6n s of the United States, residing at Youngstown, in the county of Mahoning and State of: Ohio, have invented certain new and useful Improvements in Roofing-Plates; and we do hereby declare the following. to be a full, clear, and exact descriptionof the invention, such as willenable'others skilledin the art to which it appertains to make and use the same, referencebeing hadto the accompanyingdrawings,and to letters or figures of reference marked thereon, which form a part of this specification.

Our invention relates to that class of roofing-plates in which there is a flange or fillet projecting upwardly along the edge above the central line of the plateaud afsimilanflange projecting downwardly along the edge below said central line; and the objects of our improvements are to-construct roofing-plates in which thebearings are equally distributed throughout their lengths, so that they will not kick up and yawn or gape at the joints, but will lie firmly, fit neatly, and form perfect joints, both along the flanges and at all impinging parts, and also to enable a plate, in case it becomes damaged, to be replaced by a perfect one without removing the adjoining plates.

Figure 1 represents a plan View. Fig. 2 represents a section of the same on linear. Fig. 3 represents a side view of Fig. 1, with parts of adjoining plates in section.

Similar letters refer to similar parts throughout the several views.

The plates are preferably made of glass or any vitreous material, of a diamond form, as

represented, and of any convenient size.

A represents the body of a plate, the upper half of which with reference to a central transverse line has a flange, B B, projecting upwardly around its edges, and the lower half has a corresponrlingflange, O O, projecting downwardly along its edges. The flanges are out off at the lateral angles of the plate to a vertical 1ine,touching their inner sides, as shown in Fig. 1. The upper half of the plate, at a point about one-third the distance from the central transverse line to the apex, is curved or bent downward a distance equal to the combined' thickness of the plate: and depth ot' the flange, as shown in Figs. 2 and 3,the1curved or angular portion occupying aboutthe-middle third of this half ofthe plate. The'plate is then curved or bent in the oppositedirection, so as to bring the remaining portion on aline parallel. to the central portion of the body of the plate, the upper surface of=thisportion: of the plate being in line with th'eun- 6o der surface of the central portion ofi the body of the plate. The curvatures or angles of the-- lower half of the plate are just the reverse of those of the upper half, the first curve or bend being. upward and the second one inthe oppositedirection, so that the plate whas'a flat bearingrsurface atthe ends, a straight central portion, and a curved or angularportionyand. when placed on a roof the curvatures or ran-i gles of the upper half of each plate coincide with those of the lower halves of the plates with which it is placed in contact. Thelower half of a plate touches equallyupontheflanges, and is supported by its flan gesand the flanges of the adjoining plates below, while the upper third of the body of the upper half of the plate rests upon the sheeting or laths, an air chamber, D, being left under the greater portion of each plate. Thelateralthickness of theflanges B B near their lower ends is increased by a circular outward enlargement. Through the enlarged portion, at right angles to the plane of the central portion of the plate, countersunk nailholes a a, are formed.

Bevel-headed nails, one of which is represented by b, are employed for securing the plates in position on the roof. The nails pass through the air-chamber beneath the plates before penetrating the boards on which the are laid, and a short distance points of the adjoining plates below, and the nail-heads are covered, concealed, and protected by the overlapping portion of the adjoining plates above. The size of the nails should be somewhat less than that of theholes.

The enlarged part of the flanges of plates employed for repairing may be beveled inwardly, and the nail-holes may have a down ward and outward inclination.

The plates are laid in tiers or courses, and

tier or tiers, the flanges around the upper part of the under plates interlocking with the flan ges around the lower part of the overlapping plates. Supplemental plates, of a form and size represented by the half of a plate separated longitudinally with the separated edge extended and bent at right angles, serve to finish at the gable edges or ends of the roof. The upper halves of plates having the separated edges prolonged downward are employed for finishing at the caves; and for finishing at the comb of the roof the lower halves of plates are employed. The separated edges of those on one side may be elongated to form a more perfect comb.

The comb may be capped with glass, zinc, or other suitable material, if desired.

Small plates of suitable shapes and sizes may be employed in finishing about chimneys and corners.

The use of strips of caoutchouc, felt, or other material, or of cement or putty at the joints, which requires much labor and expense in the first place, and which in time will decay and necessitate the relaying of the roof, is not required with our plates, as they form smooth tight joints, both along the flanges and at all impinging parts.

In case one of our plates becomes broken on a roof, the damage can be repaired by removing the fragments; then, with a pair of pinchers having a fulcrum near the point of seizure, the nails under the edges of the two overlapping plates, and which secured the damaged plate to the roof, areseized where they pass through the air-chamber and drawn out on a curve. The sides of the plates on each side of the space can then be slightly'elevated and a new plate inserted in place of the one removed and the nails inserted to secure it in position.

A roof covered with our plates has gentle horizontal waves passing over it at'equal distances, and nothing but the material of which the plates are made is exposed to view.

The plates may be made of various colors, and different-colored plates may be arranged in a variety of patterns or designs-upon the roof.

What we claim as our invention, and desire to secure by Letters Patent, is-

1. A roofing-plate having flat bearing-surfaces at the ends, a straight central portion, and curved or angular portions, substantially as and for the purpose described.

2. A supplemental plate having the form of one-half of the diamond-formed plate separated longitudinally, with the separated edge extended and bent at right angles, substantially,

as described, and for the purpose set forth.

In testimony whereof we affiX our signatures in presence of two witnesses.
