Description
Patented Feb. A1e, i930 @UNITED STATES JOHN S. SKOGLUND AND CRISTIAN M. NLQEBRETSON, OlEI STARBUK, MINNESOTA Roon-Sammie stuur Application led December 12, 1924, Serial No. 255,441. `Renewed January 6, 1930.
This invention relates to improvements in vide a joint cleat for strips of roofing material.
vide a connecting and retaining cleat for seams of flexible rooting materials.
A still further object of the invention is to provide a combined seaming `cleat and straight Vedge for the joints of flexible roofing materials. v
A still further object of the invention is to provide an attachable watertight joint or seam for flexible roofing materials.
With the above and such other objects in view as may hereinafter more fully appear, welhave invented the device illustrated in the accompanying drawings in which:
Figure l'is a plan view of a section of roofing embracing our invention;
Figure 2 is a perspective view thereof,
`shown partlyin section.
Like reference characters indicate like parts throughout'the following specification and inthe several views in the drawings in which 1 indicates a `roofing upon the sheathing 2 on which is laid a roofing material 3 formed in sections 3 and 3a, the'edges 4 and 5 of said sections being7 joined and seamed by means of a seaming strip 6, formed of sheet metal and being substantially S-shaped in cross section providing three layers 7, 8 and 9, the bottom layer 7 of which is flat and the intermediate layer 8 is substantially flat, While the edge 10 of the upper layer is fiat and its intermediate portion 11 is concavoconvex, its free edge 12 is curved'terminating in an angular flange 14 which, when driven into itsv place upon thel edge 4 of the vmember 3, bends a longitudinal corner 15,
forcing it 'down over the connecting bend f 16 between the layers 7 and 8 of the strip 6.
A series of longitudinally spaced apart apertures 17 are provided at the apex' portion of the convex rib 11, through which the nails -18 are driven. The other layers 7 and 8 of the strip 6 are imperforate prior to use thereof.
In operation the 6 is projected under the edge 5 of the roof- Another object ofthe invention is to prounderlayer 7 of the strip ing layer 3a until said edge is seated wholly .Within the groove 19 formed by the layers 7 and 8. -The upper layer 9 is normally spaced y suiciently far from the layer 8 to readily receive the edge 4 of the roofing layer 3 into the groove 20, formed between the layers 8 and 9 of the strip. The inner or side wall of the groove 20 is formed at right angles to the layers 8 and 9 and forms a straight ed e against which the terminal edge of ,the layer of roofing material to be seated therein is adapted to seat, the groove 20 also forming means for regulating theoverlap of the roofing layer 3. pleted the layer 9 is pressed down into place After this' operation is com jected through the aperture 17 and then driven home, the concavo-convex form of the rib 11 causing the edge 14 of the layer 9 'to bind tightly against said edge 4, thus making a perfect watertight seam connection between the layers 3 and 3a of the roofing material without the application of cement or other binder than the strip 6. The nails 18 are preferably provided with corrugated Shanks 18 in order that when driven through the layers 8 and 7 respectively, said corrugatio'ns will be engaged by the edges of the perforations formed by said nails and prevent the withdrawals of the nails even in case the nails should happen to come between sheathing boards.
Having described our invention that which we claim to be new and desire to procure by Letters Patent is:
A securing'strip for the edge portions of overlapping roofing sheets consisting of a sheet of metal bent S-shaped in cross section forming three overlapping l`layers co-acting to provide a pai' of opposing channels to receive said edge portions, the top layer of the strip being convex and having its free edge projecting -downwardly beyond the lower channel whereby a tight joint is obtained.
In testimony whereof we afliX our signatures.
