ROOF COVERING I Filed June 2 5, 1928 ieri Zfka/zez filling strips Patented May 10, 1932 FFHCE ALBERT C.-IISCHER, OF CHICAGO, ILLINOIS, ASSIGNOB TO THE PHILIP CAREY MANU- FACTURING COMPANY, A CORPORATION OF OHIO ROOF COVERING Application filed June 25,

This invention relates in general to roof coverings and has particular reference to coping and so-called flashing strips which are attached to a wall structure.

The invention consists in the features, combination, and arrangements hereinafter described or claimed, for carrying out the above stated object and such other objects as will hereinafter appear.

Generally described the invention comprises a homogeneous mixture of fiberized bituminous material preformed into strips of any desired shape suitable for capping the edges of a wall or for sealing and anchoring the ends of roof coverings at this juncture with the wall. The cap strips are preferably formed into a skeleton structure and may be employed singly or in association with filling strips to composea composite structure. The strips are self-healing to bond them in place on the wall, and it is preferable to form the filling strips less dense so that they may more perfectly weld the units into a composite structure.

In the drawings Figure 1 is a perspective view of a cap strip embodying the invention;

Figures '2 and 3 are perspective views of modifications of the invention;

Referring specifically to the drawings, numeral 2 designates a capping preformed from a homogeneous mixture of fibcrized bituminous material into strips of any desired configuration.

fluence which would cause them to crumble and fall apart. Therefore, the fibrous material incorporated therein is preferably of linear structure and uniformly distributed throughout the bituminous material ,to provide a high degree of tensile strength and prevent chipping and crumbling. The following specific mixture is given as an example of a suitable mixture:

Asphalt fifty (50) per cent, fibrous material ten (10) per cent, long fibers five (5) per cent, mineral material thirty-five to forty per cent.

This fiberized mixture is formed into strips by conventional means into strips of substantial length, each of which is provided with depending flanges 3 along the side edges, said flanges being spaced sufficiently for the strip to cap any underlying member on which they are mounted. The top surface of the cap strips may be plane (Fig. 1-) but are preferably crowned to provide inclinedv sides- 4 deflecting Water.

These strips are adapted to be attached directly to the top of. a wall 5 or may have interposed filling strips 6, which are made of substantially the same material as the cap stri s but containing less mineral material. T ese strips are formed from a mixture of about sixty per cent asphalt, fifteen (15) per cent fibrous material, and twenty-five (25) r cent mineral material. Both types of strlpsare adapted to be associated as a unit by forming the filling strip of a width to fit beneath the cap strip between the edge flanges. The mating surfaces of the strip may be contained so that the strips snugly interfit to provide a solid unit or they may be of a contour to space the strips and-provide a. hollow core igure 9) therebetween. In this latter described structure a reenforcing means mav be provided on one of the strips such as flange 7 (Fig. 3) on cap '2 to contact with the filling strip and prevent sagging. Filling strip 8 is provided with a convex surface to conform to the concave undersurface 9 of cap 10 (Fig. (i)

Beneath the coping unit right angled guard strip 11 may ai'lvantagcously be inter posed with one flange covering the top of the wall and the other extending a substantially terposed between the cap strip and a wall long distance to protect a portion of the wall structure.

relatively large and heavy they may .be formed into sections 12 and 13' and overlapped by rabbeting the edges. These are laid end to end and adhered to the wall, after which they are overlaid with the filling and capping r 75 strips. T. strips 13 are inserted betw ce'n the cap strips to prevent ingress of water at the joints.

The flashing comprises atriangular strip 15 15 laid at the juncture of the roof and wall over which is fitted strip 16, beveled along its side edges 17 to fit snugly against the roof and wall. Inthis manner the supporting structure for the roofing sheets may be 20 built up even with the raggle block to which the ends of the roof are attached.

Obviously the invention is not limited to the details of the illustrated construction, all of which may be variously modified.

. 5 Moreover it is not indispensable that all features of the invention be used conjointly as certain features may be employed to advanta 'e in various different combinations and sub-combinations.

I 30 Having described my invention, I claim:

1. A parapet building wall construction comprising a raggle block for securing the ends of roofing strips to a wall, coping strips capping the wall, and a strip covering the 35. wall between the coping and the raggle block.

2. A parapet building Wall construction comprising a raggle'block forsecuring the ends of roofing strips to a wall, coping strips capping the wall, and'guard strips interposed 40 beneath the coping extending to face the wall bet-ween the coping and raggle block.

3. Coping units comprising a cap strip having flanges extending along its side edges, and a filling strip of a width to span the 45 channel between the flanges of the cap strip.

4. Co ing units comprising a cap strip having anges extending along its side edges, and a strip spanning the channel between the flanges of the cap and having a de end- 50 ing flangefor facing a portion of a wal 5. Coping units comprising a cap strip having marginal flanges, and a right angled guard strip having one side adapted to extend between the marginal flanges and the 55 other depending therefrom to face a portion of a wall on which the units are em loyed.

6. Co in units comprising a cap s eet of fiberize bituminous material having marginal flanges, and a fiberized bituminous sheet 60 adapted to fit the cap sheet between the flanges. a I
