United States Patent ROOFING CONSTRUCTION John H. Goodwin, Greensburg, Pa., assignor to Overly Manufacturing Company, Greensburg, Pa., a corporation of Pennsylvania Application February 7, 1955, Serial No. 486,366

2 Claims. (Cl. 108-21) This invention is for an improvement in roofing and relates particularly to a batten type of roofing in which the roofing sheets at their edges have a water-tight engagement with the batten.

The invention is for an improvement in roofing of the general type disclosed in my prior Patent No. 2,447,065, granted August 17, 1948. In my said patent there is disclosed a batten type of roofing in which the edges of the roofing sheets are bent up along the sides of a batten which extends down the slope of the roof, and there is a cap strip which serves to clamp the edges of the sheets to the sides of the batten.

The principal object of the present invention is to provide a roof construction of this type in which the batten is formed of metal, and in addition to forming a waterproof connection between the batten and the roofing sheets, also provides an entirely waterproof connection between the batten and the roof structure preventing entrance of the water flowing over the roof into the structure upon which the batten is mounted.

In the drawings forming part of this disclosure:

Fig. 1 is a longitudinal vertical section through the batten portion of a roof constructed in accordance with my invention;

Fig. 2 is a transverse vertical section taken along the lines II-II of Fig. 1; and

Fig. 3 is a transverse vertical section taken on the lines IIIIII of Fig. 1.

In the drawings, reference character 2 designates a roof support which may be of concrete, structural metal, wood, or any other material commonly used for the roofing structure of a building. Mounted on the roof support are a plurality of battens 3, only one of which is shown in the drawings, all others being of similar construction. These battens extend up and down the slope of the roof. They are formed with two upwardlyextending side flanges 4 and 5 connected at their base 'by a member 6 which extends continuously between and beyond each flange 4 and 5. At each side of the said flanges the member 6 has slotted openings 7 therein through which extend the fastening members 8 securing the batten to the roof structure. Intermediate the vertical dimension of each flange 4 and 5 is an inwardlyextending substantially horizontal flange 9 terminating in an angularly-disposed flange 10. These flanges 9 extend longitudinally of the length of the batten and their flanges 10 are disposed in horizontally spaced relation. Mounted on the batten flanges 9 and 10 are a plurality of members 11 having at each side thereof suitably shaped inwardly-extending openings to receive the ends of the batten flanges 9 and their associated flanges 10 so that the members 11 are slidable thereon longitudinally of the batten. At substantially the center line of the batten, each member 11 has a tapped opening extending therethrough for reception of a screw-threaded fastening member. These battens may be of relatively light weight metal and are most economically made of an extruded metal such as aluminum, brass, or any other suitable metal.

The roofing sheets are designated 13. They have their edges turned upwardly to provide substantially verticallyextending flanges 14 disposed adjacent the preferably slightly diverging upwardly-extending batten flanges 4 and 5. The upturned roof flanges 14 each have an,

inwardly-turned lip 15 extending therealong, these lips hooking over and overhanging the top of the flanges 4 and 5 as clearly shown in the drawings.

There is a cap strip or cover strip 16 having downwardly-extending flanges 17 that fits over the batten so as to be supported thereon and the flanges 17 embrace the upturned edges 14 of the roof sheets. At suitably spaced intervals longitudinally of the length of the cap strip are suitable openings for reception of a threaded fastening member such as a machine screw 18, the shank of which extends inwardly of the cap strip and is engaged with the tapped opening in the member 11 slidably mounted upon the batten flanges 9 and 10.

In assembling the roof, the battens 3 are first secured to the roof structure by the fastening members 8 extending through the elongated openings 7 in the member 6 of the batten. In those cases where the roof is laid across structural members or concrete having preformed openings therein for reception of the fastening members,

the elongated openings 7 permit slight adjustment necessary to admit matching up with such preformed openings. The roof sheets are then put down. Usually the flanges 14 will have been formed in advance and the lips 15 will also usually have been formed in advance. After the roof sheets have been put in place the cap strip 16 is fitted into position and the fastening members 18 extending through the cap strip 16 are engaged with the members 11 mounted within the batten. As clearly shown in the drawings, as the cap strip is fastened in position it forces the lips 15 of the roofing sheets into engagement with the tops of the batten flanges 4 and 5 forming a waterproof seal. The flanges 17 of the cap strip 16 embrace the flanges 14 of theroofing sheets, forming a tight joint or connection therewith.

The construction herein disclosed and described is thoroughly water-tight because any wind-driven rain or melted snow which may be driven up the vertical surfaces of the flanges 14 of the roofing sheets will drop off the downturned lips 15 of the roofing sheets into the gutter formed by batten flanges 4 and 5 and bottom member 6 so as to drain out longitudinally at the lower end of the batten. Should any water leak in under the heads of the screws 18 and run down these screws, such water will also fall upon the member 6 of the batten and drain out longitudinally at the lower end of the batten. The fastening members 8 securing the batten bottom member 6 to the roof structure are disposed up wardly of the batten flanges 4 and 5, and beneath the roof sheets 13 so that no water reaches these fastening members, and hence cannot leak in around the fastening members into the building structures. The elongated openings 7 through which the fastening members 8 extend also provide for relative movement between the batten members 6 and the member 8 during expansion and contraction of the batten.

While I have shown and described one particular form of my invention, it is to be understood that this is the present preferred form and the various details of construction are for purposes of illustration and not limitation except as made necessary by the scope of the appended claims.

I claim:

1. A batten for use with a cap strip in retaining metal roof sheets in assembled relation, comprising a base portion adapted to be disposed in longitudinal alignment Patented May 12, 1959,

aseasm with theslope of the roof, upwardly extending flanges on said base portion disposed in inwardly spaced align ment with the longitudinal edges of the base portion and forming therewith an imperforate channel for carrying any water received therein down the slope of the roof, suitably spaced apertures in said base portion outwardly of said flanges for reception of fastening members securing the batten to the roof supporting structure, inwardly extending opposing spaced flanges on said upwardly extending flanges and disposed intermediate the vertical height of said upwardly extending flanges, each said opposing flanges terminating in a portion disposed in a direction transverse to the plane of the body of said flanges, cap strip attaching members slidably mounted upon said opposing flanges, each said member extending across the space between said flanges and having suitably shaped openings, in opposite sides thereof slidably receiving the adjacent edges of the opposing flanges to form a continuous connection between the batten upwardly extending flanges, and means forming suitably tapped openings in said members between said opposing flanges for reception of screw threaded fastenersextending' downward between the batten side flanges when securing a cap strip to the batten.
