. noon CONSTRUCTION.

To all whom it may concern:

Be it known that I, CHARLEY BURNETT, a citizen of the United States, residing at WVashington Court House, in the county of Fayette and State of Ohio, have invented certain new and useful Improvements in Roof Construction, of which the following is a specification.

This invention relates to roof construction and aims particularly to provide the.

type of structure which may be both very readily applied v and which will be proof against rattling or ready dislodgment by the action of the wind when the latter reaches considerable velocity.

Still a further object of the invention resides in so forming and arranging the structure that the metal roofrsections, when used in connection with inclined rafters and a ridge pole, may be suitably slid andoverlapped and secured tothe ridge pole and in this manner eliminate the possibility of wind and air from entering the interior of the structure.

Another object'of the invention resides in a structure whereby the overlapping edges of the roof sections'are secured in'position to prevent the admittance of moisture ,to a position beneath the metal sections and to also prevent corrosion of the attaching nails.

The preferred embodiment of this invention is shown in the accompanying sheet of drawings, in which similar characters of corresponding parts, and in which: n

Figure 1 is a partial side elevation and partial section of a roof section constructed in accordance with my invention,

Figure 2 is a transverse vertical section of the structure shown in Figure 1 taken on line 2-2 of Figure 1. 1

Figure 3 is an enlarged vertical section taken through one of the rafters, showing the manner of connecting the roof sections thereto, and, V

sections are preferably concaved, as is shown, and have their longitudinal edges bent to conform in shape to the rafters themselves. Along the edges of these sec tions, there are provided a plurality of aper- Patented Feb; 7, 1922.; Application filed February 12, 1917. Serial No. 148,033. R I

tures or punchings so formed that a burr 5 v 1 is formed which projects upwardly, as is shown particularly in Fig. 3. Through these apertures the attaching nails 6 are made to pass, but in order to form a tight joint and to prevent the admission of moisture be- 5 neath the roof surface each nail is provided with'a washer 7,whioh washer is'preferably of lead. I As the nail is driven down, this washer embeds itself in the burr formed and in turn wedges it tightly against the nail or the washer itself is embedded in this burr'so that a very tight joint is formed. I

In order to-form a tight joint along the ridge pole, the end which abuts this ridge pole is slitted, as shown at 8, the depth of this slit' being the amount it is necessary to bend up the flaps 9 thus formed due'to the concavity of the metal plate sections. Thus, by comparing Figures 1 and 2, it will be noted that the plate'sections are slitted a distance sufficiently to cause a tight joint to be'formed between each of the flaps f9 thus'formed, the line ofcontact'varying'in length from the edges toward the'center; In

thus bending the flaips up, the slitted: ends also overlap and it is through this over lapped portion that the sections maybe, fit-T tached to the ridgepole, as is showman-10;"

This prevents the flap sections from pulling apart, although, if desired, additional nails may be placed through the flap "portions.

Finally, a ridge roll of the type shown at 11' is placed in position to give afinished appearance. j

From the foregoing description, it will be apparent that I have provided a type of structure wherein a very rigid roof is made and one wherein also all jointed connections are made water tight.

The ridge roll itself is preferably formed from sheet metal, and is so shaped as to adapt itself to the configuration of a ridge pole and the co-operating upper portions of the roof sections. In this instance, said ridge roll comprises a substantially fiat upper portion 12, which is adapted to be positioned upon the corresponding upper surface of the ridge ipole 1, fastening elements 13 being employed to secure the same in a rigid position; The portion 12 terminates in obliquely and downwardly directed sides 14, which extend substantially parallel with the roof sections 4. The lower edges of the sides 14 terminate in right angularly disposed supplemental sides 15, which are situated at right angles to said roof sections,

the lower edges of the supplemental sides being formed so as to fiushly engage with the undulating cross sectional vformation of the roof sections. By virtue of this ridge roll construction and the co-operation which exists between the same and the roof sections, a structure is provided which is conformed to include a fiat upper portion ar-' ranged to directly contact with the upper J portion :of 'said pole, fastening devices ar-v ranged to pass through the fiat upper portion of said ridge roll and to directly connect the latter with -said pole, said roll being further formed to include sides disposed parallel with-said sections and in spaced relationship therefrom, and integral supplemental sides disposed. at} right angles to the first mentioned sides, ssaid supplemental sides having their lower-edges undercut to evenly engage with the undulating curva- V ture'of said sections. 7 7

2. In a roof structure, the combination with a ridge pole,"of a plurality of concave metallic roof sections, cooperatively "supd' in connection, with said pole and sloping downwardly therefrom, a ridge roll formed to include a substantially flat upper portion, reversely inclined sides extending downwardly from the flat upper portion of said .roll and in parallelism with said roof sections, supplemental sides disposed at the lower edges of said firstnamed sides and in angular relation with respect thereto, the

said supplemental sides having the lower edges thereof formed to evenly engage with the concave surfaces of said sections, the said sides serving to cover the connections between the said roof sections and said pole, and fastening devices arranged to pass through the flat upper portion of said roll, and to connect the latter with the upper portion of said pole. 7

3. In a roof structure, the combination with a ridge pole, of a plurality of transversely concave metallic roof sections having the upper edges thereof secured to the opposite. sides of said pole, a metallic ridge roll disposed upon the upper surface of said pole and arranged to cover the] meeting joints defined by the connection between said sections and said pole, the said ridge roll being formed to include reversely and down-j wardly inclined sides extended away from said pole and in substantially parallel rela- V t-ionship with said roof sections, ysupplemental sides disposed .at the lower edges" of said first named sides and in angular relation with respect thereto, thesupplemental sides having their lower edges formed .to conform with the transverse configuration of saidsections, and fastening devices situate'd between said-sides forconnecting the roll to the upper part'of said pole. I

In testimony whereof I affix mysignature in presence of two witnesses.
