Letters Patent No. 101,635, dated April 5, 1870.

IMPROVEMENT IN ROOFING.

The Schedule xefen'edto in these Letters Patent and making part of the same.

To all whom it may concern.- I

Be it ,known that I, THoMAs'A. MAKLBBIN," of Annapolis, in the county of Anne Arundel and State of Maryland, have invented a new and useful Improvement in Rooing; and I do hereby declare the' following to be a full and correct description of the same, sufcient toaenable others skilled in' the class to which my invention appertains to fully understand and apply the same, reference being had to the ac companying drawing which forms part of this speciicatiomand in which- Figure 1 isa perspective view of part of a roof, constructed according to my improvement.

Figure 2'is a perspective v`iew of a similar part, showing the manner of attaching the boards to the beams, and of securing the side dashing. A

Figure 3 is a sectional end view of one of the boards, showing a modified shape of channel.

Figures 4,5,.6, 7, 8, and 9 are detached perspective views of the dilierent ashings.. Y

Like letters of reference indicate' like parts in the severalfgures. l 5 y x The `natureY of vmy invention consists in peculiarlyshaped metal strips, covering the seams between each' two boards of aboard roof, or any cracks in the boards,'

the said metalstrips Ybeing held inplace by the spring of their inwardly-bent` sides against the inclinedsides of the channels formed-in the surface of saidr boards near their side edges, .thus doing away with fasteningv by nails, and consequentrusting. I

In the drawing-y, y g; A represents thei beams 'of. a roof, to which. the

boards B are nailed lengthwise: .1

These boards have channels C cut in their surfaces,

near their side edges, 'said channels being inclined in@ wardly, as clearly shown in iig. l.

The nails securing the boards lto the beams are driven between the channel and the .side edge of the boards, as shown ing. 2.

In figs. 2 and 3 are shown modifications of the. channels O, one side only of the same being incliued,i.

and the other at right angles to the width of the board. By cutting them in -this latterway, nioref space is gained for the water to run downn -D are metal strips, having their sides bent inwardly, as shown at d, iig. 6, the body of this strip being bent outwardly to form a ridge, e. These strips D cover the seams between each two boards, they being sprung over the seam into the channels on contiguous sides of boards, so that the inwardly-bent edges of the metal strips bear against theinclined sides nearest to each olther ofthe two channels, thus being securely held in p ace.

Successive pieces of metalstrips covering one'seam Voverlap eachother downwardly, as shown in iig. 1. l l

Should any crack occurin any ofthe boards, chaunels, as described, are formed yon each side of thel and assist incollecting and camping the rain or snowwater to the glitter E, forming gutters themselves at right angles to gutter E.

In iig. 4 is shown one kind of side flashing, used for cornices or side pieces of frame-work on a roof.

zThe loweredge is bent, as shown, to seize into the I channel of the last beam on that side of the roof; the

upper edge is bent at right angles, or nearly so, to the body ofthe strip, and is placed into a slit made in thc vertical Aboard, as' shown in fig. 1.

E ig. '5 shows a side flashing used at the side of a roof, which has noframe-work rising above it. One edge of 'it seizes under the inclined side of the channel ,of the -lastboardon that side 'of' the roof, while the other part of the strip is bent to pass over the edge of the roof.

Figs. 7,8, and 9 showtheto'p flashing. The first is for a roof having two inclined sides. It consists of a strip of metal, bent lengthwise to lay onthe edge of the roof, extending downwardly to both sides. Where v it passes over the strips D it is slightly bent up, outwardly, to conform to the shape of strips D, to which theyare soldered. v

'Fig 8 shows sucbflashing Where the roof bias but one side, and' ig. 9 shows an end-pieceof top hashing. In using myixnprovement, all the nails securing the boards to the beams are covered bythe strips or dashing, and', as the latterare secured without nails, the

rusting of the latter from rain and inclemency of the weather is obviated, and thus the rotting of the wood where the nails pass through it prevented.

The channels conduct the waterto the gutter, and

vthe bent shape ofthe body of the strips allows them .to give with the expansionland contraction of the boards from the iniiuence of the atmosphere.

Having thus described my invention, Vhat I claim as new, and desire to secure by Letters Patent, is-

l. The combination of the `channels C and metal 4 fstrips D, constructed substantially as and for the purposes -set forth..

2. Theside and end flashings, constructed substantially asdescribed and showniniigs. 4 and 5, in combination with channels C, substantially as set forth.

The above specification of my improvement in roofing signed this 4th day of December, 1869. THOMAS A.l MAKlBBIN.
