yBOARD ROOF.

SPECIFICATION forming part of Letters Patent No. 530,009, dated lNovember 27, 1894.

Application filed July 28, 1894'. Serial No. 518,859. (No model.)

To a/ZZ whom t may concern:

Be it known that I, JOSEPH P. BROWNLEE, a citizen of the United States, residing at Galva, in the county Iof Henry and State of Illinois, have invented certain new and useful Improvements in Board Roofs, of which the following is a specification.

This invention relates tothe class of wooden roofs, and particularly to a board roof, and its novelty will be fully understood from the following description and claims when taken in connection with the annexed drawings. Roofs of this character now and defective owing to the fact that the corrugations, notches or grooves upon the top or outside are equidistant, forming the whole surface'v of the boards into a water channel, and should there be any defect in the boards, which is invariably the case, leakage is the sure result. If the notches, corrugations, or grooves are not equidistant-the board surface between them is dat, and the same result is experienced. It has been found essential and particularly desirable in roofs of this character, used especially for sheds, barns, te., to

-v have the under side of the boards constructed with means for Ventilating such structures, and for preventing' the roof boards from warping. The roofy battens now in use are defective, as to draining of the water, for the same reasons, above mentioned, and as to making a positively water tight joint, because of their faulty construction. It is to overcome the foregoing objections found in roof boards, battens and joints, that my invention is intended.

' The object of the invention is to provide roof boards of such peculiar, yet simple and cheap construction, that any ordinary common grade of lumber can be used.

A further object of the invention is to provide a roof that will ventilate the structure which it covers, and of such construction that the boards thereof will not warp, or the joints become spread, even though common cheap lumber be used; and that will confine the water in draining to less board surface.

A further object of the invention is to provide boards having their under side provided with Ventilating grooves, and the outer side, not regularly corrugated, V shaped or in use are faulty Ior otherwise defective boards.

from this shoulder it slants on an notched, as is well known in the art, but said upper or outer side having a sufcient number of small grooves, at aconsiderable distance apart, and the board surface between the grooves are slightly convexor curved from one groove to another.

A still further object of the invention is to provide a batten for the board joints of simple, cheap, and novel construction, and means for securing the batten in position to make an effective water tight joint.

The invention consists in the novel construction and arrangement of parts, as will be hereinafter fully described and set up in the claims.

The invention is clearly represented in the accompanying drawings, in Which- Figure l is a perspective view of part of a roof embodying my invention. 'Fig 2 is a perspective view of my improved batten, looking at the under side. Fig. 3 isa perspective view of a portion of my roof with the battens removed. Fig. 4 is a cross section of a moditied form of joint.

The same reference numerals denote thesame parts in the drawings.

The roof boards 1, may be made from any rough stock lumber of ordinary quality, the under side having a series of Ventilating grooves 2,Y with bearing surfaces 3, between them, which are intended to rest upon rafters. Not shown. Upon the upper side of the boards two or more water channels 4, according to the width of the board are made, and the surface 5, between the water channels is made convex or slightly curves from one channel to the other, so that water will fall off the main or convex board surface to the said channels upon each side, and leave said surface free from water; thus avoiding leakage through the said surface, by reason of knotty From the channel nearest the board edge, the top of the board slants upwardly to a shoulder 6, and

angle upwardly toward its edge.

The construction of only one board is here described, as each and every board is of the same construction.

The outer portion or top of the batten 7, has its sides formed in two curves, each producing IOO a slightly concave and convex draining sur face from the pinnacle of the'batten, which is preferably semicircular, toits side edge. The inner side or bottom of the batten slants downwardly from its center upon each side to the shoulder S, and from this shoulder it slants downwardly on each side at an angle, to the hatten edge, the shoulder as well as the angle surfaces being parallel. The inclines, and shoulders of the hatten register with said like parts of the roof boards, when the battens are placed in position, and all the angle surfaces, water channels, shoulders and grooves of the battens and boards extend the Whole length of each. The interval or distance between the shoulders S, of the battens is made slightly less than the distance between the shoulders 6, of the boards, so that in making the joint between the boards, the battens are driven down over the shoulders 6, until the board edges are brought tightly together. It will be observed that the shoulders 6 and 8, are straight or vertical.

Referring to the modication shown in Fig. 4, the shoulders 9, and 10, are made on an angle and at a different degree from the slanting surfaces, and of sufficient depth to allow the hatten to be driven down farther, should the joint become open, by the action of the elements on the boards, while the angle surfaces 11, are at a greater angle than the angle surfaces 12. To further insure a close and permanently fitting joint, short fasteners 13, are driven through the convex por tions of the hatten toward the central edge line of the roof boards, and longer fasteners 14, are driven through the concave portions of the hatten across the said central edge line of the boards.

It will be observed that a roof made as hereinbefore described, will not admit any water to flow toward the joint, and should Water strike the outer inclineslwhen the hatten has not been driven clear down) it cannot touch the joint because of the shoulders closely engaging each other. lt will be observed that in the construction of this roof no fiat or angle surfaces are exposed.

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

1. In a board roof, the battens having their outer sides alternately convened and concaved, their inner sides formed of parallel shoulders with an interval or space between them, and parallel angle surfaces also with a space between them, combined with the boards having Ventilating grooves on the under side, their tops having a series of water channels, and slightly convex surfaces merging into the said channels, each board having near its side edges angle surfaces divided by a shoulder, the latter with the former adapted to be engaged by said similar parts of the battons, substantially as set forth.

2. The combination in a board roof, of the boards having Ventilating grooves on the under side, provided on the top with water channels connected by a slight convex board surface, and having near their side edges angle surfaces divided by a slanting shoulder, one surface being upon a different angle from the other, the hatten having like angle surfaces and shoulders with a space between the shoulders and a space between the surfaces, in which spaces the side edges of the boards fit and are drawn together, substantially as set forth.

3. The combination in a board roof, of the battens having the inner side formed of parallel shoulders and parallel angle surfaces, the former dividing the latter and all extending throughout the length of the hatten, and the roof boards having like shoulders and angle surfaces to those of the battons and adapted to be engaged by the latter to hold the boards together, substantially as shown and described.

4. A roof batten comprising a strip of uniform thickness throughout, the inner side formed of parallel shoulders, and parallel angle surfaces, the former dividing the latter, and all extending throughout the length of the strip, the outer side of the strip being alternate] y concaved and convexed longitudinally, substantially as and for the purpose set forth. i

In witness whereof I hereunto set my hand in the presence of two witnesses.
