8 Claims.

Those types of roofing in which metallic roofing sheets have their side edges upturned or flanged, either to form a standing seam or a batten seam, have often not proven satisfactory because their construction has been such that sufiicient free lengthwise movement due to contraction or expansion of the .sheets has not been permitted. Also, in case of standing seam roofs, destructive total area horizontal movement has often been unintentionally allowed. Either of these faults lead to quick failure of the roof. Furthermore, the joints of the standing seam or batten seam roofing have been formed and finished on the job, making the labor cost for such roofing a large part of the total cost.

The objects of the present invention are to provide a roofing structure using roofing sheets of the flanged side type in which the adjoining upturned or flanged edges are joined together and any sheet from afiecting or exerting pressure on the next adjoining sheet.

A further object of the invention is to provide a seamed type roofing structure in which the roofing sheets or plates are held down against I the roof by clips fastened to the sheathing or rafters, and which has a snap on or slide-on preformed or partially pre-formed covering memher which contacts with the sides of adjacent flanges of sheets or plates, thus reducing by a large percentage the labor required to install the The invention further consists in the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

Referring to Figs. 1 and 10 of the drawings, the roofing material is inthe form of plain sheet metal l5 with upturned or flanged sides 16 as shownsin Figfl or of corrugated sheet metal body H with upturned or flanged sides 18 as shown in Fig, 10, the corrugations extending, either vertically or horizontally of the sheet to reinforce the same. These sheets or plates are of certain definite lengthsv and are associated together lengthwise by overlapping the lower end of an upper plate with the upper end of a lower plate which upper end is secured to the frame of the roof by nails I9 or other suitable fastening. Lengthwise extending lengths of assembled plates are arranged next to similar sets of assembled plates at each side and are joined together at their upturned or flanged sides It by a joint structure embodying the invention... In Figs. 2 and 3 this joint structure includes a series of clips 20, fastening means for said clips, and a covering 2 l. The clips 2b are small curved sheet metal pieces punched to take two or more long nails 22 which are driven into the framework 23 of the roof, the nail heads exerting a clamping force on the clip which in turn by engaging the tops of the adjacent flanges l6 exerts a downward thrust thereon so as to keep said sheet or plates in proper vertical alinement without, however, preventing relative sliding movement between the clip, and either of the sheets or plates engaged thereby, so that contraction and expansion of the metal roofing material due to changes of temperature may be taken care of without danger of having the roof buckle or of loosening the fastenin means. To provide a weathering joint, cover members 2| arearranged to act as hoods to project down over the exposed upper ends of the flanges l6 and cover over the space between said flanges. This covering or the members 2| are formed by forming a sheet metal strip into generally channel shape form with the sidesthereoi reversely curved to form curved parts 24 and 25,

these channeled strips having overlapping engagement at their ends with each other as shown in Fig, 1, with the lowermost strip anchored at its upper end to the roof frame by a nail 26. These covering strips may be pre-formed, and the curved parts 24 and 25 will permit them to be secured in position by pushing them down over the clips 20, so that their curved edges 25 are free to snap into yielding engagement with the sides of the flanges l6 and into engagement with said clips at the curved parts 24 so as to connect them with the fastening means or nails 22. The connection of the covering member 2i with the flanges I6 permits relative movement between said strips and the flanges 16 of the roofing plate or section to compensate for any movement of these parts due to contraction or expansion of the metal thereof.

Instead of the form shown in Fig. 2 the cover strips 2| of generally channel form may be formed with longer sides having straight side portions 21 in engagement with the sides of the flanges [6 as shown in Fig. 4.

To keep the flanges a definite distance apart the clips 28 may have spaced lengthwise extending grooves 29 to receive the upper edges of the flanges, as shown in Fig. 5, these clips being secured similarly to the first form by the nails 39 and having cover strips 3| snapped thereover, similar to Fig. 2.

Another form of the joint is shown in Fig. 6 wherein the clip 32 is bent at its sides to form a flat top part 33 for the fastening means 34, and the cover strips 35 are formed to provide-pointed ridges 36.

In the form shown in Figs. 7 and 8 the clip is formed to provide a tube 31 flanged at its bottom 38 and at its top 39, the fastening means 40 passing down through the tube and exerting pressure thereon to in turn put pressure on the flanges l6 of the roofing plates to hold them in position, the upper flange 39 of this clip forming a gripping ledge adapted to be engaged by the cover strip 41 which is generally similar to the cover strip 2| of Fig. 2 and having curved sides similar to the sides 25 and adapted to snap over the outer edges of the flanges 39 and engage the sides of the flanges IS.

The cover strips above described may be formed at the factory or in some instances cover strips initially formed to a readily stackable form as shown at 2P Fig. 9, may be finish'formed during the assembly of the roof parts on the roof.

In those cases where it is desired to more widely separate adjoining sections of the roofing from each other as by a batten strip 43, the joints shown in Figs. 11 and 12 maybe used. In Fig. 11 the clip 44 is secured to the top of the batten strip 43 by the nails 45 fastening said strip 43 to the roof frame 45, and a cover strip 41 extends over the top of the batten strip and the ends of clip 44 and has curved portions yieldingly engageable with the sides or the flanges Hi.

The form shown in Fig. 12 is similar to that of Fig. 11 except that the clips 48 in this form are provided with spaced grooves 49 to receive the upper ends of the flanges l6. These clips are fastened to the roof and to the batten strip 53 by the nails and the joint is covered and held in laterally alined position by the cover strip 52.

The form shown in Figs. 13 and 14 is similar to that of Figs. 11 and 12 except that the cover strip 53 is formed to he slid onto the clips 48',

similar to the clips 48, and which are fastened to the roof and to the batten strip 54 by the nails 55. After the cover strip 48 is initially slid over the clips as shown in Fig. 13, this cover strip together with the clips are bent downwardly against the side flanges I5 of the roofing sheets or plates l5 as shown in Fig. 14.

In all of the above forms the upstanding edges of adjacent roofing sheets are free to move lengthwise relative to each other and to the covering hoods for said edges.

I desire it to be understood that this invention is not to be limited to any particular form or arrangement of parts except in so far as such limitations are included in the claims.
