JAMES D. JONES, OF DUNN VILLE, KENTUCKY.

METAL-ROOF CONSTRUCTION.

Specification of Letters Patent.

Application filed November 3, 1917. Serial No. 200,182;

To all whom it may concern:

Be it known that I, JAMES D. J owes, a citizen of the United States, residing at Dunnville, in the county of Casey and State of Kentucky, have invented new and useful Improvements in Metal-Roof Constructions, of which the following is a specification.

This invention relates to roof constructions and among other objects in view, it has for its purpose the provision of companion plates respectively having interfitting connect-ions with each other and formed so as to effectively establish a perfect water tight connection. between the several plates throughout the entire surface of the roof.

An object of the invention is to form plates identical so that the same can be readily stamped into their formation by a single stamping machine.

A further object of the invention is to provide a roof construction, the individual plates of which are so formed and connected to each other that independent lateral and longitudinal movement of the plates individually is preventedf The invention consists in the features of construction, combination and arrangement of parts hereinafter fully described and claimed, reference being had to the accompanying drawings, in which Figure 1 is a top plan View of a. roof constructed in accordance with my invent1on;

Fig. 2 is a plan view of one of the plates;

Fig. 3 is a sectional view showing the interfitting connection between a series of plates;

Fig. 4 is a. cross section through a plurality of plates taken on line 44 of Fig. 1;

Fig. 5 is a top plan View of one of the plates in blank form.

As stated, it is my purpose in the presentinvention, to provide mating or companion plates of a roof construction whereby, when the plates are assembled, they Wlll have such an interfitting connection with each other as will establish a water-tight connection between the several plates, and while it is found desirable to rib all the plates in substantially identical alinement for sealing the seams between the several longitudinal rows of plates, I do not propose to limit myself to the precise arrangement that will only be referred to for the purpose of illustrating an extremely practical combination in arrangement with the other features of my invention to be described.

As shown in Fig. l of the drawing, the roof construction consists of a plurality of longitudinal sets of plates having overlapping engagement with each other. plate comprising the roofing is identical, I will limit the following description to the construction of one plate and state its relation to the plates adjacent thereto.

Each plate is formed from a rectangular sheet of metal and provided at points adjacent to the opposite longitudinal edges thereof with spaced longitudinally extending ribs 1. The transverse edgev portion 2 of the plate is cut from the free terminal 2 thereof in an inward converging direction as denoted by the character 3 forming on one end of the plate a tongue l adapted to be subsequently bent downwardly and under the plate so as to lie parallel to the under sur face thereof. The opposite edge portion 5 is cut from the terminal 5 in an inward diverging (llIQCl'llOll as at (3, providing on this end of the platen tongue 7, that is finally bent upwardly and over so as to lie parallel to the upper surface of the plates and extend in a direction opposite to the heretofore mentioned tongues 4. The ribbed edges ofthe alternate sets of plates overlap the ribbed edge portion of the remaining sets, while the ordinary securing elements such as nails 8 pass through all of the ribs as is obvious from Fig. 1 of the drawing. Upon the bending'of the tongues in the position better disclosed in Fig. 2 of the drawing, at the edge of formation of the tongue 4 thereon, is formed at points beyond the point of bending of the tongue rib-bed projecting corner portions 9. \Vhereas on the opposite end of the plate, I provide atpoints beyond the point of bending the tongue, substantially triangular shaped ribbed corner portions or projections 10, which when the plates are in overlapped relation, or disposed edge to edge, that is, upon the engage ment of the tongue 7 with the tongue 4, the corners 10 will snugly fit on the ribs 1 of the adjacent plate and establish a water tight connection between the plates as indicated at 11 in Fig. 2. The object in slitting the edge 2 as shown, is that the outer transverse edge of the tongue will be of a width substantially equaling the transverse extent of the plate, consequently the sub- Patented Mar. 11, 1919.

As each stantially V-shaped corners of the tongue being ribbed, will snugly engage in the rib 1 of the plate and establish a water tight connection at the opposite adjacent ends of the plates, upon the interlocking engagement or" the tongues with one another.

By having the tongues formed as above stated, it will be noticed that when the plates are in assembled position, the edge portion 2 lies upon one of the adjacent plate-s in the set and has its edge portion 5 disposed under the remaining plate in the set. Attention is also called to the fact that when the plates are assembled, the coacting tongues prevent independent longitudinal movement of the plates, while the overlapping ribs prevent independent transverse movement thereof, independent of the securing elements 8.

From the foregoing description, taken in connection with the accompanying drawing, the advantages of construction will be readil v apparent to those skilled in the art to which the invention relates, and while It have described the principles of operation of the invention, together with the device which I now consider to be the best embodineat ave ment thereof, It desire to have it understood that the device shown is merely illustrative and that such changes may be made when desired as are within the scope of the appended claim.

ldlaving thus described the invention, what is claimed as new is As a. new article of manufacture, a roof construction comprising a plate formed from a rectangular sheet of metal and ribbed at spaced intervals in a longitudinal direction, two of the end portions being cut in an inward diverging direction to form a plurality of tongues, certain of said tongues being bent inwardly 'and under so as to lie parallel to the under surface of the plate while the remaining tongues are bent upwardly, thence inwardly and over so as to lie parallel to the upper surface of the plate, the formation of the tongues providing oppositely arranged V-shaped corner portions, the said corner portions upon the assemblage of olate adapted to overlie one another and esiablish a seal tight joint.

in testimony whereof I aiiix my signature.

JAMES DI JONES.
