This invention relates to sheet metal building construction and particularly to means for joining or connecting the edges of metal sheets, particularly of corrugated roofing. The eneral object of this invention is to provide a joint or connecter between the edges of two metal sheets of corru ated roofing of such character that the 'omt will be water-proof and that it will e iminate the waste caused b lapping.

A further ob ect is to provide a connection whichwill prevent snow or rain from blowing under the roofing along the lap.

A further object is to save time and labor in forming the corru ated roof and provide a connecter which wi aid or guide the workman in keeping the joints in straight lines, thus adding to the appearance of the roof or siding.

My invention is illustrated in the accompanying drawings, wherein Figure 1 is a top plan view of a plurality of roofing sheets or connecting elements or 'omts engaged therewith in accordance wit my invention; 1

Figure 2 is a section on the line 2-2 of Fi re 1;

igure 3 is a like view to Figure 2 but showing a variation in the cross section;

Figure 4 is a top plan view of the two sections or connecters telescoped;

Figure 5 is a section on the line 55 of Fi re 4;

Figure 6-is a transverse section through a connecter showing one means whereby it may be connected to a metal purlin;

Figure 7 is a section on the line 7-7 of 2, A and B are two corrugated sheets 0 metal such as are ordinarily used for roofing or siding. Such sheets as this are usually overlapped at the joint for about 1% corrugations. Such a joint as this is not completely water-proof and water might pass along said joint by capilla attraction and so that water will penetrate eneath the roof. Furthermore, this overlapping of the sheets is wasteful. To avoid this, I provide a connecter or (.jioint designated generally 10 having a me ally disposed, approximately cirenlarged head 17. The head 11 is then sli cular head 11. This bead is nearl closed at 12. The metal on each side of t 's head is earned laterally from the contracted portion 12 outward in opposite directions as at 13 and then extended upward, downward and inward as at 14 so as to form what ma be termed lateral beads. The side edges 0 the sheets A and B are forced down over these lateral beads and underneath the medial bead 11 so that the edges of the sheets A and B will en 'age the medial bead at the neck 12.

f course, the upper edge of each sheet A or Bis disposed beneath the overlap of an upper sheet and the lower edge of each sheet A or B is overlapped upon the sheet below. As illustrated in Figure 1, the joint 10 at its endshas extensions 15 forming the extensions of the flat portions 13 of the lateral head which are apertured for the passage of nails where this device is to be applied upon a wooden building. These jointor connecting members 10 are designed to have an desired standard length to corres 0nd wit the lengths of the metal sheets. has these joint or connecting members may have lengths of four, five, six, seven, eight, nine and twelve feet.

Where it is necessary to join one connecter 10 with an adjacent connecter, two connect- 'ers are telescoped into each other as illustrated in Figure 4. In this case, the head 11 of one connecter receives within it the bead 11 of the next connecter below, but preferably the lateral beads of the upper connecter will be inserted in the lateral beads of the lower connecter. This is illustrated in Figure 4. Where this connecter or joint is to be used on frame buildings, it is formed, as before stated, with the outwardly projecting lugs 15 by which it may be nailed to the sheathlng of the building or to the joists. Where this connecter is to be used on a metal frame buildin two bolts 16 are disposed, one on each si e of the purlin or other structural element, each of these bolts having as on to these bolts so that the shank o the bolt extends through the neck 12 and the head of the bolt is di osed within the bead 11. Thus these bolts old the connecter in place. Obviously the bolts may be connected to the metal framing of the building in any desired manner, provided the heads of the bolts are so formed as to fit'within the bead 11.

While I have illustrated in Figure 2 a con necter 10 which is formed with an approximatel circular bead 11 and with somewhat elliptical lateral beads, I do not wish to be limited to this. In Figure 3, I show a con necter designated 10 which is exactly like the connecter 10 except that the lateral beads are approximately triangular in cross section instead of being approximately ovoid in cross section.

In Figure 6, I illustrate a connecter 10 in which the medial bead 11" is approximate 1y triangular in cross section. lit will thus be seen that the exact form of the connecter in cross section may be varied widely without departing from the spirit of the invention as defined in the appended claims.

The connecter constructed in accordance with my invention not only makes a waterproof joint between two adjacent sheets and eliminates the waste caused by overlapping of the sheets, but such a joint aids or guides the roofer in keeping the joints in a straight line, thus adding very greatly to the appearance of the roof or siding. The joint illustrated will hold the edges of the corrugated sheets in proper position at all times and the lateral bead constitutes ducts whereby any water which may enter the joint will be carried downward and be discharged at the eaves with no chance of the water entering the joint and collecting between the sheets and the sheathing of the roof.

lit is very essential that the connecter 10 or 10 shall have a flat base with means to fasten the connecter securely to the sheathing boards to prevent the connecter from being turned up on either edge by wind getting under the roofing sheets and thus lifting one head or lateral channel higher than the other, causing an overflow of water. It is also particularly necessary that the margins of the lateral beads be extended downward and inward so as to secure a good contact withthe downwardly and inwardly extending margins of the lateral sheets, as shown most clearly in Figures 2 and 3, themar ins of the sheets A and B being extended ownward and inward, preventing water being blown out of the channel durin a heavy rain and wind storm, which pro uces whirling motion in the channels. The margins of the beads being extended inward and downward forces water back toward the neck of the connecter and out at the ends. If the margins of the lateral beads terminated perpendicularly against the roofing sheets or the margins of thhe lateral beads do not extend downward and inward and conform to the lateral margins of the roofing sheets, a whirling motion aeeae'm of the water in the channels forces water upward and outward between the margin and the roofing sheets, thus causing the water to go inside of the building instead of out through the channels.

A further object in extending the lateral margins of the beads inward and downward is to close the openings at the tops of the channels, which prevents the channels getting clogged. The margins of the roofing sheets being extended inward over the tops of the lateral beads holds the roofing sheets securely and forces upward on the edges of the roofing sheets, forcing them against the bottom of the central head. The pressure is uniform for the entire length of the roofing sheet and prevents rattling.

While I have illustrated my joint as applied toa corrugated metal roof or siding, I do not wish to be limited to this as fiat sheets might be used in place of corrugated sheets provided the lateral edges of the sheets are upwardly and then downwardly bent so as to extend down over the lateral beads of the joint and into position on each side of the metal bead of the oint.
