Be it known that GEORGE A. REYNOLDS, of the i city of Rochester, county of Monroe, and State of N ew i York, have invented acertainnew and useful Improve` ment in Machines forRolling Metallic Roofin g-Plates,

. of which the following is a specification.

Y Nature of the Iurentfion.

Y This invention consists of series of rollers for rollingthe 4plates throughdiatwisa having, at the ends, and forming fixtures thereof, `a corresponding series of graduated rollin g-dies, forproducin g the seamin'g .ben ds ofthe plates, as hereinafter described. v General Description. i In the drawingf Figure l'is a plan of the machine. j

Figures 2, 3, 4, and 5, elevations of the successive rollersand dies, with corresponding views of theform of the rolled plate `at `successive stepsof the rolling A is `the frame of the machine, having snitableberls I3 B, for the entrance and exit of the plate, and havlng, also, side gauges 'G C, `which are set c vactlyto V`the widthof the plate, and `serve to keepitin position.

` "as it is passed through the rollers. y At a suitable distance apart ontheframe is mountcd a series of rollers, 1 2 3, &c.`, of any desired number in the series, each set beingmade upl of two rollers, D E, situated one above the other, with justspaoe enough between for the `sheet-rnetal plate lto pass through. These rollers are driven by gears a-.t al bb,

" arranged in any desired manner, so as to give a constant forward motion to` all the rollers.

At one endof the set of rollers 1 are arranged rolli ing-dies: k l, `which, simply consist of angularfaces of i slight incline, whichcorrespond and intermatch.

i l 'lhelplate` G, as it passes through, is formed with a slghtbend, d, of the edge, as'shown at iig.` 2.1,

',Lhe next set of rollers, 2 has similar dies, a2 l2, but

`of a greater angleor incline, and they produce a greatcr bend ofthe edge` (lof theplate G, as shownfin iig. 43; and so ou, for any desired number of the sets of roller-dies, gradually bending the'edge of thc metal `up`more and more, till the `last set is reached, when the dies 7d P aremade. vertical, thereby turning the edge Aclef the plate to a rightangled position asit runs through, asshownin g; 4.

After passing these dies?, 4the `vertical edge d of the platestrikes intoA theangle of small roller-dies m n,

which overlieoneanother, and lthe cxtreme edge is bent inward betweenthe vertical faces of the dies,

thereby producingthe horizontal flange f,`bent inward i from edfe :t as shown in 5.

. e i l ferent', the dies are of a somewhat diierent shape.

The dies g'h g Itl 'g2 h2 have thesameinc'liue for turning up the vertical edge fi of the metal plate G, but they have, in addition, narrow horizontal rims p q, which intermatch and form the horizontal part s of 4 the bend. Furthermore, they have inclined faces t-u tl al t2 fue, which are the reverse of g h, &c.,and which 'gradually produce the downward vertical bend r of the plate, shown complete in figs. 4 and 5.

I am aware that it is not new to form theseamingedges of metallic roofing-plates in a shape somewhat similar to that above described; and I am also aware that a machine is already in use in which small gradnated roller-dies are employed for the purpose; but,

in such case, thedies are not connected with rollers that pass the plate through between them', but are of "small size, and situatedhorizontally at the sides of the machine, and the plate itself is clamped in abcd which moves between the side dies, the edges of the metal only projecting out Aso as to reach the dies.

' The great advantage of my arrangement over that is in the use of the main rollers D Ewith the dies forming a part and fixture of the same, in which ease the sheet is held steady in place, and is run through only just so fast as the dies can act upon it without straining or injuring the metal.

The dies and rollers themselves feed the plate along, and thc plate cannot bc moved so fast as to crimp or strain, which is the ease where the movement of the bed to which' the plate is clamped is independent of the dies which act upon the edges of the` plate.

Another great advantage of my invention is, that I can run the plates through of any desired length,

even of the roof itself,y while in other devices heretofore used'onlycertain and given lengths could be made,

`notvexeeeding thebed in which it was clamped.

I also claim au advantage in the -use of the rollers D E, which remove allthe dents, bends, 'and irregularities in the inct'liu passing through, making it correspond with the edges which arc bent by the dies, and delivering it- .in a smooth` and unbroken sheet, ready for application upon thc-roof. 'Y

V Asimplebed clamp cannot do this, as the pressure is insufficient over the whole surface; besides which, the edges, in passing 'through the dies, become expanded or stretched toa greater degree than'the body of the metal, thereby producing bend and irregularity in the plates, and frequently tear. i

I contemplate, in some instances, setting the inner set or sets of the rollers higher than the outer ones, so

as to produce a convex or rounding outline, in which case, when the plates are run through, they will be delivered of convex form, suitable for covering car- Claims.

What I claim, and desire to secure by Letters-Patent, is-

1. In n machine for rolling metallic roofing-plates, a. series or train of rollers having the dies forming a. part and fixture of the rollers themselves7 and gradnated as described, and the whole so arranged as to produce the double eect of rolling the plate and forming the seeming bends at one operation, as' specied.

2. The arrangement of the series of rollers D E and dies k l k l2 kil, and finishing-dies m n at one end, and the dies g h gl h1 g2 h2 at the other, as described. In witness whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
