7 Claims. (01.108 10) 7 f f I This invention relates to a tile supporting strip and more particularly pertains to a strip for holding roofing tile in place on a roof structure.

An object of the invention is to provide a ribbon or strip of the above character which embodies a series of extruding loops for effecting connection between the strip and wire ties connected to roofing tile or the like.

A particular object of the invention is to provide a construction or formation in the extruded loop elements of the strip whereby such elements are strengthened or reinforced to resist their being flattened out under pressure and also strengthened against distortion or breakage under loads to which they are subjected, and furthermore render the loops of such contour as to conform to the end portions of wire loops engaged therewith.

With the foregoing objects in view together with such other objects and advantages as may subsequently appear the invention resides in the parts and in the combination, construction and arrangement of parts hereinafter described and claimed and illustrated by way of example in the accompanying drawing in which:

Fig. 1 is a view in perspective illustrating a length of the tile supporting strip:

, Fig. 2 is a view of the strip as seen in front elevation:

Fig. 3 is a view in section taken on the line 3--3 of Fig. 2:

Fig. 4 is a view in transverse section taken on the line 44 of Fig. 2:

Fig. 5 is a detail in perspective illustrating the manner of fastening a tie wire to the extruded loop of the strip:

Fig. 6 is a view in longitudinal section taken on the line 6-6 of Fig. 5:

Fig. 7 is a view in cross section as seen on the line 1-1 of Fig. 6:

Fig. 8 is a detail in perspective illustrating the manner of efiecting interconnection between the ends of overlying strips, as in splicing.

Referring to the drawing more specifically, A indicates generally the tile supporting strip which consists of a strip or ribbon of sheet metal, such as cooper or brass, and which strip is substantially flat and of rectangular cross 5 section.

In carrying out the invention the strip is formed throughout its length with a series of spaced extruded loops, the formation of which loops constitutes the essence of the present in- 55 vention.

In forming the loops B the strip A is fed through a suitable die mechanism whereby, pairs of parallel slits 9 and H) of corresponding lengths, are formed at uniformly spaced intervals longitudinally of the strip and the material of the strip between the pairs of slits is pressed outwardly to form a loop.

In order to strengthen the extruded loop thus formed. the material thereof is formed of arouate cross section as particularly shown in Fig. 4 10 with the upper side or face of the loop, concave and with its under side convex. The loop is also arched longitudinally and thus has imparted thereto a double arch construction throughout the length thereof. 15

The loops converge inwardly from their ends to their mid-length, as particularly shown in Fig. 2, thus forming the loops of a width slightly less than the width of the slot H formed in the strip A .on extruding the metal extending between the slits 9 and [0. By thus narrowing the loops it is possible to nest a pair of loops on superimposed strips as shown in Fig. 8 which facilitates uniting the strips together, or in other words, forming a splice.

The strips thus formed are designed to serve as runners for effecting connection between tile or slabs to roofs, being positioned to extend in the direction of the incline of the roof and supported on and attached to the roof surface; the strips being positioned with the extruded loops projecting upwardly. In attaching tiles or slabs to the strips or runners, wire tile ties l2 attached to the tile are passed through the loops B as shown in Figs. 5 and 6, in looped engagement 35 therewith, as by bringing portions of the tie projecting from opposite sides of the loops B together and interconnecting them, as by twisting. The tie wire is thus formed with a loop M the end portion of which seats on the convex 40 under side of the loop B, as particularly shown in Fig. '7.

In efiecting the splice as shown in Fig. 8, a tie wire is passed through the lowermost of the nested loops thus fastening the superimposed 5 strips together.

I claim:

1. A tile supporting strip comprising a ribbon of sheet metal having extruded loops pressed therefrom at spaced intervals longitudinally thereof, said loops being arched in transverse cross section.

2. A tile supporting strip comprising a ribbon of sheet metal and a series of extruded loops projecting from one side of said ribbon, said loops being of arched cross section and being concave on their upper faces and convex on their lower faces.

3. A tile supporting strip comprising a ribbon of sheet metal having extruded loops pressed therefrom at spaced intervals longitudinally thereof, said loops being arched in cross section, and the sides of said loops converging from the ends thereof to their mid-lengths.

4. A tile supporting strip comprising a ribbon of sheet metal and a series of extruded loops projecting from one side of said ribbons of arched cross section, said loops being concave on their upper faces and convex on their lower faces, the sides of said loops converging from the ends thereof to their mid-lengths.

5. A tile supporting strip comprising a'ribbon of sheet metal, a series of extruded loops projecting from one side of said ribbon at uniformly opposite sides of said loops inclining toward each other from the ends thereof to their mid-lengths. '7. Ina tile supporting strip, a ribbon of flat sheet metal, an extruded loop pressed from said ribbon intermediate the side margins thereof, said loop having a transverse cross section in the form of an inverted arch.
