HTTDRNEY Patented Nov. 24, 1931 UNITED STATES PATENT OFFICE GEORGE B. DE GANT, OF IBELLAIRE, OHIO, ASSIGNOR TO WHEELING STEEL CORPORA- TION, OF WHEELING, WEST VIRGINIA, A CORPORATION OF DELAWARE METAL ROOFING SHEET Application filed October 30, 1929. Serial No. 403,447.
This invention relates to improvements in metal roofing sheets, and more specifically to that type of roofing sheets having edges adapted to overlap to form weatherproof joints.
The primary object of the invention is to provide a roofing sheet having its lateral edges adapted to occupy overlapping relation to the corresponding edges of like sheets for forming a joint having therein a drain channel or trough for the reception and discharge of water or moisture which, by siphonic, capillary or other action may enter beneath the overlapping ed es.
A further ob ect is to provide a lap joint of the character mentioned which is practically proof against admission of water to the sheathing upon which the roofing sheets are mounted.
In describing the invention in detail, reference is herein had to the accompanying drawings, in which- Figure 1 is a diagrammatic view in perspective of a fragmentary portion of a roof embodying roofing sheets constructed in accordance with my invention; and
Figure 2 is a cross section of my improved lap joint.
Referring to said drawings, 1 designates the roofing sheets which are made of sheet metal, each thereof having formed along one of its lateral edges and elevated above its plane a pair of parallel ridges or corrugations 2 and 3 which are separated to form therebetween a longitudinal channel or trough 4.
Said ridges 2 and 3 are preferably of truncated cone shape in cross section, as shown, each having divergently inclined legs surmounted by a substantially flat top or crown portion. The bottom of the trough 4 occupies the plane of the body of the sheet, as shown.
The opposite lateral edge of each sheet is likewise provided with a pair of parallel ridges or corrugations 5 and 6 similar to the ridges or corrugations 2 and 3, the same having such dimensions that they are adapted to ride upon and closely embrace, or interfit with, said ridges or corrugations 2 and 3.
However, the channel formed intermediate the ridges or corrugations 5 and 6 is of materially less depth than the channel or trough 4, the bottom thereof being thus adapted to occupy a position sufiiciently elevated with respect to the bottom of the trough 4. that there is afforded therebetween a drainage channel of large capacity.
It will be noted that, with the ridges 5 and 6 of one sheet fitted in overlying relation to the ridges 2 and 3 of an adjacent sheet, the crowns and the outer, or non-confronting, faces of the legs of the ridges 2 and 3 are closely engaged, as are also the upper end portions of the confronting legs of said ridges 2 and 3. This relation is maintained by the attaching nails 7 which are driven through the overlapping crowns of the ridges, as shown.
The inclined, or oblique, abutting faces and the tops of the interfitting ridges reinforce one another and resist collapsing forces, such as may be created by one walking on the roof, or by the driving of nails through the contacting tops of the interfitting ridges.
lVater which may pass upward between the engaged surfaces of the outer legs of the ridges 2 and 5 and thence pass inward between the crowns of said ridges may flow downward between the inner legs of said ridges 2 and 5 to the trough 4, whence it may drain from the roof. Any water which could possibly reach the under side of the roofing sheets must pass upward from the trough over the ridge 3that is, between said ridge 3 and the overlying ridge 6. Obviously, such a possibility is extremely remote.
What is claimed is 1. A lap joint for roofing sheets comprising sheets adapted to occupy overlapping relation along their meeting edges, one of said edges having therein a pair of corrugations relatively spaced to form a longitudinal trough therebetween, and the other edge having therein a pair of corrugations with an intermediate channel, said corrugations being adapted to interfit in overlapping relation to those of the first mentioned edge, but having the intermediate channel of materially less depth than that of said trough.
2. A lap joint for roofing sheets comprising sheets adapted to occupy overlapping relation along their meeting edges, one of said edges having therein a-pair of parallel up- 5 standing corrugations disposed relatively to form an intermediate longitudinal trough, and the other edge having therein a pair of corrugations-with an intermediate channel, the corrugations of the last mentioned edge 10 being adapted to interfit in closely overlap- I ping relation to those of the first mentioned edge except that the channel thereof has materially less depth than the trough of the first mentioned edge.
15 3. A lap joint for roofing sheets comprising sheets adapted to occupy overlapping relation along their meeting edges, one of said edges having therein a pair of parallel upstanding corrugations disposed relatively to form an intermediate longitudinal trough,
the bottom of said trough being disposed substantially in the plane of the body of the sheet, and the other edge having therein a pair of corrugations with an intermediate channel of materially less depth than that of said trough, the corrugations of the second edge being adapted to overlap and interfit with those of the first edge.
4. A lap joint for roofing sheets compris- 30 ing sheets adapted to occupy overlapping relation along their meeting edges, one of said edges having therein a pair of parallel upstanding corrugations disposed relatively to form an intermediate longitudinal trough, each of said corrugations having divergently inclined legs surmounted and connected by a substantially fiat crown, and the other edge having therein a pair of corrugations substantially corresponding to and adapted to overlap and interfit with those of the first mentioned edge, there being formed between the corrugations of the second mentioned edge a channel having materially less depth than that of said trough. I In testimony whereof, I afiix my signature. GEORGE B. DE GANT.
