SHEET METAL ROOFING Filed April 11, 1930 Ihuenior.

' S 1 Conner, ,B WWWW Patented May 3, 1932 SOMERVILLE VAUGHN CONNER, OF NEW ALBANY, INDIANA SHEET METAL ROOFING v Application filed April 11,

My said invention aims to provide sheet metal roofing having overlapping channeled edges of such form that the sheets may be readily and economically manufactured, easily laid without danger of being out of parallelism or alinement, and which, when in assembled position on the roof will have a maximum efficiency in excluding water from penetrating through the roofing.

With these and other objects in view the invention includes the novel construction hereinafter described and defined by the appended claims.

My invention is illustrated in the accompanying drawings in which Figure l is a sectional view partly broken away showing a pair of roofing sheets in assembled condition as applied to the roof.

Figs. 2 and 3 are separate views (in section) of the individual sheet portions.

Referring by reference characters to these drawings, 1 designates one of the sheets and 2 the other. These are shown as having overlapping channeled portions or corrugations forming the single seam shown, but it will be understood that the opposite edges of the sheets (which are broken away) would'be joined to other sheets in a similar manner,

' the number depending on the extent of roof- The sheet is provided with an upstanding channeled portion of inverted truncated V- shape spaced back from the edge or margin of the sheet and comprising reversely inclined walls 1a and 1b of equal height and surmounted or united at thetop by a flat portion 10. Beyond the bottom of the wall lb is a portion 1d lying in the same plane as the main body ofthe sheet and provided with an angularly upturned margin or edge 16.

The channeled portion of sheet 2 is also of approximately inverted truncated V-shape but its flat top is provided with a re-entrant V-shaped portion or channel as and for the purpose hereinafter described.

1930. Serial No. 443,508.

This channel and re-entrant portion comprises a wall 2a designed to rest against the outer face of wall 1a, and a short or narrow wall 26 designed to rest upon the upper portion of the wall 1?), these walls being connectedat the top by a flat portion 20 designed to rest on the fiat top portion 10. The opposite side 2?) of the re-entrant channel terminates in a flat top portion 2d from the edge of which the main channel wall 26 extends downward to the main body of the sheet.

Such channel formations are very easily formed by rolling or stamping methods, and in laying the roofing are easily assembled in exact parallelism or alinement as the inclined walls 2a and 2b guide the overlying sheet into exact position and hold it perfectly straight due to the accurate interfitting of the parts.

As the overlying sheet is pressed down, by the nails 3 driven through the fiat top portions 20 and 10, the former is pressed down on the latter while the wall 26 is pressed down against the upwardly inclined edge 16.

The joint thus formed is one which is firmly held and thoroughly braced and is proof against leakage.

Should water work in under the wall 2a and between surfaces and the re-entrant V portion 2b-20 will cause it to be deflected downward into the channel 165 and be carried out at the bottom of the sheet.

I claim:

A sheet metal roofing comprising an underlying member of general inverted truncated V shape, having a flat top portion, and having also a trough portion at the lower end of one of its downwardly diverging sides, said trough being formed of a substan- S tially horizontal lateral extension, and an upwardly extending terminal flange, and an overlying section also of general inverted truncated V shape, having at its central upper portion a V shaped groove, one wall of which bears against the same side wall of the underlying member to which the said trough portion is connected, the other wall of said V shaped trough spacing the inclined Wall of the overlying member away from the Wall of the underlying member, said inclined wall of the overlying member also covering the trough at the lower end of the underlying member, said overlying member having also a flat portion to rest on the flat portion of the underlying member to receive a nail which passes through both members, said overlying member also having its'other inclined wall fitting against the remaining inclined wall of the underlying member, substantially asde= scribed. V

In testimony whereof, I aflix my signature.

S. VAUGHN CONNER.
