Letters Patent No. 111,307, dated January 31, 1871.

IMPROVEMENT IN METALLIC -RCIOFINGS.

Th Schedui referred to in these Letters Patent and making part of the same.

To all whom- 'it' may concern Be it known that I, GEORGE W.-BL1ss, of Springeld, in the county ot' Hampden and State of Massachusetts, have invented a new and improved Covering forltoofs; and 1 do hereby declare that theiollowiug is a i'ull, clear, and exact description thereof, reference being had to the accompanying drawing making part of this specification, and to the letters of reference marked thereon, in which- Figure l is a plan View of one modification of my invention, showing its form before it is stamped up in the die;

Figure 2 is a reversed plan ofthe same after heilig stamped;

Figure 3 is a side view of the saine;

,i Figure et is another modification, showing the forni before it is stamped up in the die;

Figure 5 is a reversed plan ofthe same after being stamped; and

Figure 6 a view ot' aportion ot' a root' covered with various modifications of my invention.

My invention relates to a covering for roofs, *which is intended to take the place of common slatcs thatl are now used for that purpose; and

It consists ot' plates ot' metal, which are irst ent into proper form, and are afterward placed in a dic, by theaction ot' which the edges of said plato, or a portion ot' the same at one end, are turned or stamped down, so as to give an appearance of sutlicient thickness to the end exposed to the weather, and prevent the rain or wet from beating. underneath.

The plates being flexible, they may be bent orfitted to any form of rooi'.

To give greater strength to the plate, if desirable, eorrugations or ribs may be formed in the surface thereof, by the saine die; and at the same time that the edges are stamped up, and may extend longitudinally along the plate, or diagonally vacross it, or in any other direction; or they7 may be arranged in iigures or patterns, so that when the covering is laid uponV the roof, the corrugations may form any desired pattern, or any desired combination ot' patterns.

'lo enable others Skilledin the art to inake and use my invention, I will. now proceed to describe the same.

In the drawing- A represents a dat plat-e, which may be made of any desirable metal. iron, -being suitably flexible, and easily wrought and cut into the form shown in iig. 1, itslower cud heilig somewhat wider than the upper' part ot" the plate, and extending down at the pointed endsay aquarter of an inch, more or less, than. the plate will be when finished.

The dot-ted lines c' in tig. 1 show the form oi' the I prefer iron, or galvanized plato when iinished, and the continuous line c shows its torni before heilig stamped up.

The plate, as shown in iig. l, is subjected tov pressure ina die, and the surplus metal, shown by the space betweenthe dotted line c and the line o, is turned ont to nearly a perpendicular `position to the main part vof the plate A.

'lhat part of the plate below the dotted li'ue a shows about the proportion of the wholeY plate that is ex` posed to the weather.

A concave groove,-o, may be stamped in thesur-h faoe of the plate, extending` around the edge of that part of the plate which is exposed to the-weather, or, instead of extending around therentire Vedge ot' the plate, two or more such grooves may extend Alongitudinally along the plate, or diagonally across it.

Any desirable pattern may be stamped upon the surface ot' the plate, which may be either "sunken or raised upon the outside.

This pattcrnwould serve to give the plate strength in the saine manner that strc ight eorrugations or ribs would, and the piates would present armuch better appearance when laid.

In iigs. 4; and 5 is represented another modifica# tion, in which theplate is made rectangular when finished, its form before being stamped up being shown in iig. 4.

The space between the ldotted line c and the continuous line c shows the surplus metal, which is turned up into a position perpendicular to the main portion of the plate, as shown clearly in ltig. 5, 'c showing the turned edge. r

rlhe last-mentioned rigs. 4 and 5 show the plate as' plain, which, for some purposes, may vbe sufficiently strong without the ribs or corrugations.

Figfi shows different modifications of th'eniinven` tion, laid upon a root', and they may be differently corrugated or oruamented, so as to present aYariet-y fof patterns upon the same root'.

`Fig. f3 shows the thickness of the platel as`it appears when iinished, the edge oi the metal, which is turned out, beingshown at c. This gives an appearance of thickness to the lower end of the plate when laid, and makes it Astitfer than it would otherwise be, and prevents the lower' end of the plate from becoming loosened, or turned up, so as to admit the rain or wet.

Even with any pattern .or corrugations stamped upon the plate, it Sutticiently flexible to allow of its being bent to fit any curve or surface of any roof.

This is cheaply made, as the plate may he stamped out at the same time that the edge is turned, and the pattern or corrugations stamped upon it, the whole being made at one opera-tion oi' the die; and, if' made of iron, the plates may be painted sutiiciently 'to prevent the iron from rusting hy exposure to the weatherfzind the plates nailed to the roof, holes being made therein for that purpose.

Having thus described my invention,

That I claim as new, and desire to secure ters Patent, is-

An improved covering 'for roofs, consisting of metallie plates A, having the edges turned :tt c, :md

hv Let- Ind set forth.
