ROOFING SHEET-ANCHORING APPARATUS Filed nec. 15. 196e 3,444,658 ROOFING SHEET-ANCHORING APPARATUS Klaus Gbel, Zeughaus Str. 41, Trier, Germany Filed Dec. 15, 1966, Ser. No. 602,067 Claims priority, application Germany, Jan. 11, 1966,
Int. Cl. E04d 137,14, 5/14, 3/36 U.S. Cl. 52-94 5 Claims ABSTRACT OF THE DISCLOSURE A holder attached to roof sheathing includes an inner tongue section and a complemental outer channel section embracing the tongue. The tongue and channel sections are spaced apart for receiving between them the upper fold of a roofing sheet edge portion formed into a reverse bend. The lower fold of the reverse bend is unrestrained, to be varied in size corresponding to the expansion or contraction of the sheet in response to temperature changes. The upwardly projecting reverse bend of the rooting sheet edge and the portions of the complemental sections enclosing the rooting edge prevent entry of water and wind between the rooting sheet edge and the roof sheathing. The inner tongue section includes a portion sloping downwardly away from the tongue edge over which water can flow to drain from the space between the cooperating sections.
This invention relates to apparatus for anchoring roofing sheets and for covering roof edges.
It has been a problem to attach roofing sheets satisfactorily and to protect roof edges adequately from penetration of moisture between the roofing sheets and the underlying roof sheathing, which moisture would cause deterioration of the sheathing. Therefore, it is a principal object to provide sheet anchoring apparatus which will securely attach roofing sheets to the roof edges and prevent access of moisture to the space between such roong sheets and the sheathing.
An additional problem associated with conventional application of rooting sheets by nailing them to sheathing is the tendency of the sheet edges to be moved relative to the sheathing caused by alternate contraction and expansion of the sheet material in response to temperature changes. Such relative movement pulls the sheet-holding nails out of the sheathing. Consequently, it is an important object to provide sheet-anchoring apparatus which permits movement of one sheet edge in response to such temperature changes with a minimum of force being exerted on the opposite sheet edge which may be joined to another sheet and nailed to the sheathing in overlapping relationship in conventional manner. It is a further object to provide sheet-anchoring apparatus which can be installed quickly and easily.
An additional important object is to provide such apparatus which covers and protects the roof edge to prevent weathering and especially to prevent wind from entering between and exerting a force to separate the roofing sheets from the sheathing.
The foregoing objects can be accomplished by providing sheet-anchoring apparatus including a holder attached to roof sheathing, an inner section secured by such holder yand a complemental outer section. The inner and outer sections provide a space between them for receiving the edge of a roofing sheet which has been formed into a reverse bend upstanding above the general upper surface of the sheet and which includes upper and lower folds. The upper fold of such reverse bend is inserted between overlapping portions of the complemental sections which extend inwardly from the roof edge. The
3,444,658 Patented May 20, 1969 p lCe lower fold of the bend is unrestrained, to be varied in size corresponding to the expansion or contraction of the sheet in response to temperature changes. The reverse bend of the roong sheet edge and the portions of the complemental sections enclosing the roof edge prevent entry of water and wind between the roofing sheet edge and the roof sheathing.
FIGURE 1 is a top perspective of sheet-anchoring apparatus of the present invention and FIGURE 2 is a verticzfal section through the apparatus as installed on a roo FIGURE 3 is a top perspective of a modified form of the sheet-anchoring apparatus and FIGURE 4 is a vertical section through the apparatus installed on a roof.
In the form of the sheet-anchoring apparatus shown in FIGURES 1 and 2, an outer section 1 complementally ts over an inner section 2 and is snapped onto and held by such inner section. The inner section slidably receives in a cavity the head 4 of the T-shaped holder 3 which can be fastened to roof sheathing R by nails or screws extending through slots 11 and 12. Teeth 5 in the cavity of section 2 mesh with teeth 6 on opposite edge portions of head 4 for selectively adjusting the elevation of the inner section 2 corresponding to diiferent structural characteristics of a roof edge.
The form of attaching apparatus shown in FIGURE 1 is especially suitable for roofs having relatively short horizontal extents so that inner section 2 can be slid conveniently longitudinally onto holder head 4 and held in constant elevational position by engagement of teeth 6 on opposite edge portions of the cross flanges 4 with selected teeth 5 on the adjacent inner surface of section 2. Such teeth are kept in mesh by engagement of the backing flanges 9 and 10 with the side of head 4 opposite the teeth 6. Outer section 1 also is installed by sliding it lengthwise parallel to the roof edge with its lower arm 19 engaged beneath the lower edge of section 2.
In the form shown in FIGURE 3, the lingers 9 and 10' snap over the edges of holder 3'. The holder is secured by nuts and bolts to an angle bracket 7 secured to roof sheathing R by screws extending through slots 11 and 12. Holder 3' can be adjusted vertically relative to bracket 7 by selective engagement of teeth 7' on the outer face of the upright llange of such bracket and teeth 8 on the adjacent face of the holder 3. A slot 13 is provided in holder 3 to receive the bolt 13'. The upper section 1 snaps over the lower section and projection 22 on its outer lower edge is received in rabbet 21 of section 2'. t
The cantilever arms 17 of sections 1 and 1' in FIG- URES l and 3 form return bends into which extend the cantilever arm 16 or 16' of section 2 or 2', respectively, such free ends being spaced apart to form a slot 18 for receiving the edge of a roof sheet therebetween. The margin of such roof sheet S is formed as an upstanding reverse bend, the upper curve of which is received in slot 18. The edge of the sheet is bent slightly downward and is held between staggered projections or ribs 14 and 15 on sections 1 and 2, respectively.
Suicient space is provided adjacent to the opening to slot 18 to accommodate the lower curve of the reverse bend and to permit its flexure to compensate for contraction or expansion of sheet S in a direction perpendicular to the reverse bend, as indicated in broken lines in FIGURES 2 and 4, in response to temperature changes. The sheet can also contract or expand without restraint longitudinally of the sheet-anchoring apparatus by sliding of the reverse bend lengthwise of the anchoring elements. Tests have shown that use of sheet-anchoring apparatus of the present invention prevents joint separation between roof sheets due to temperature variations.
Rain water or other moisture which collects on roof.
sheet S cannot penetrate between the roof sheathing R and sheet S because of the upstanding reverse bend in the sheet margin. If, during a heavy rain, water should be forced upward, over and around the bend, it will ow between sections 1 and 2 and run out, with section 2 protectively encasin g the roof edge.
In FIGURE 3, the upper edge of the under section 2' is provided with a ange 23 inclined downwardly to its edge for supporting the margin of sheet S. Such strip may extend downward to and rest on a layer of cork C or other insulating material underlying the roong sheet and simultaneously tends to hold section 2 in ybearing engagement with holder 3'.
I claim as my invention:

Sheet-anchoring apparatus for a roof edge, comprising a first strip having a supporting portion extending along the roof edge and a generally at tongue projecting inwardly from said supporting portion, a second strip including a channel embracing and spaced from said first strip tongue, one side of said channel forming a free edge, and a rooiing sheet having a substantially at portion, a iirst fold spaced from said substantially flat portion folded around the edge of said first strip tongue and received between the opposite sides of said tongue and 2 4 in which a portion of the second strip adjacent to the channel extends to overlie and is spaced above the upper side of the first strip tongue and receives therebelow the upper portion of the roofing sheet rst fold.
