UNITED STATES WILLIAM STRONG, 0F NEAR SPRINGFIELD, OHIO.

SHEET-METAL ROOFING.

Application filed April-10, 1924. Serial No. 705,577.

T 0 0U 'zn/10m t 'may confirm.:

Be 1t known that l, lVrLLIAM STRONG, a citlzen otl the United States, resulmg near Springfield. in the county of Clark and` such a manner as t0 positively prevent the leakage of water at the jointure of the sheet metal sections.

A further object of the invention is to provide a device of the above mentioned character, wherein the sheet metal sections may be expeditiously assembled and secured to the sheathing in such a manner as not to expose the nails or other securing means provided therefor.

A further object of the invention is to provide a device of the above mentioned character, which is simple in construction, inexpensive, strong and durable and furthermore adapted for the purposes fory which it is designated. i

Other objects and advantages of this invention will become apparent during the course of the following description.

In the accompanying drawing forming part of this specification and in which like numerals designate like parts throughout the saine:

Figure 1 is a sectional view through my invention showing the same in assembled position.

FigureI 2 is a similar view with the parts shown in position previous to the crimping of the hook portion.

.Figure 3 is a fragmentary detail perspective view of one of the sheet metal sections.

Figure 4 is a detail perspective view of the securing plate, and

Figure 5 is a fragmentary detail perspective view of the contiguous `sheet metal section.

In the drawing wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates a securing plate which is stamped of metal and is provided with suitable apertures such as are illustrated at 2 for providing a means for receivingr nails or other suitable fasteningr means indicated at 3 whereby the plate is supported on the sheathing A in the manner clearly illustrated in Figures 1 and 2 of the drawing. Extending upwardly and at an angle to the securing plate 1 along one of the longitudinal edges thereof is the flange 4. The upper longitudinal edge of the flange 4 is curved downwardly to provide al hook 5, the purpose of which will be presently described. j

Supported on the sheathing A, on one side of the securing plate 1 is the sheet metal section G and the same has its longitudinal edge provided with the upwardly extending flange 7, the same being disposed at substantially the same angle as the flange 4 formed on the securing plate 1 and as is clearly illustrated in Figures 1 and 2 of thedrawing, the flange 7 of the sheetmetal section 6 Aabuts the under side of the flange 4.v The upper edge of the flange 7 is provided with a hook portion 8,and the same is of such a construction as to be received within the hook portion 5 formed on the upper edge of the flange 4.

The contiguous or adjacent sheet metal section 9 is adapted to overlap the securing plate 1 in the manner clearly illustrated in Figures 1 and 2 of the drawing and the longitudinal edge thereof is provided with' the upstanding flange 10 which extends along the upper side face of the flange 4 in the manner as is clearly illustrated in the drawing. The upper edge of the flange 10 is provided with a depending hook portion 11 and the latter is of a greater length and size than the aforementioned hook portion, and the hook portion 11 extends around the hook portions 8 and 5.

When the sheet metal sections 6 and 9 respectively are in positlonwith respect to the securing plate 1 in the manner shown in Figure 2 of the drawing, the suspending portion of the hook 11 is crimped inwardly as shown at 12 whereby to provide a locking means to prevent the vertical movement of the section with respect to the adj acentv sec tion and securing plate. Inthis manner an interlocking joint for the contiguous seotions of the sheet meta-l roof is provided and the same is of such construction as to pre- 'vent any possibility of water leaking therethrong The provislon of an mterlocklng joint for contiguous sheet metal sections of roofing of the class above described is very simple and effective and will at all times retain the sheet metal sections snugly in engagement and there will be no possibility of the scctions becoming separated and further by covering 'the securing plate, the fastening means associated therewith will not be disengaged from the sheathing.

While I have shown the preferred embodiment of my invention, it is to be understood that various changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention and the scope of the appended claim.

Having thus described my invention, what l claim is In an interlocking joint, contiguous sheet metal sections of rooting, a securing plate having one end thereof bent upwardly at an oblique angle to provide a ilange, the upper end thereof being curved and terminating in a lip, an obliquely disposed flange formed on the edge of one of said sheet metal sections and adapted to be disposed against one side of the aforementioned liange, the upper edge of the last mentioned iange being curved and adapted to be received in the curved portion on the flange of the securing plate, the other section being adapted to overlie the securing plate, a ilange formed thereon and adapted to extend along the opposite Side of the flange of the securing plate, the upper portion of the flange on the second section being curved and disposed over the curved portion ot' the aforementioned flanges, the curved portion of the last mentioned flange terminating in a depending strip which is adapted to be crimped into engagement with the lip formed on the free edge of the curved portion of the flange formed on the securing plate, said depending portion adapted to be disposed substantially parallel to and spaced from the aforementioned flanges and having an offset eX- tension at its terminal.

In testimony' whereof I aiiix my signature.

VILLIAM STRONG.
