ROOF Filed Feb. 17', 1957 Ill 7 FEJZ INVENTOR. Donald F Fradetfe ATTORNEYS.

Patented Sept. 13, 1938 UNITED STATES PATENT OFFICE ROOF Donald F. Fradette, Cleveland, Ohio Application February 1'1, 1937, Serial No. 126,181

7 3 Claims.

The invention relates to an improved roofing or roof covering, and-more particularly relates to an ornamental breaker strip adapted to cover the adjacent paralleling edge portion of the shingle plates positioned below the breaker strip.

fold or support rests upon the breaker strips v rather than upon the plates below the strips. Due to the fact that the breaker strip is thickest near its outer end tends to keep the support from slipping down over the roof when used thereon.

The accompanying drawing shows by wayof example an embodiment of the present invention.

Figure 1 is a fragmentary plan view of a roof showing the breaker strip mounted thereon in accordance with the invention, a portion of a shingle element being broken away.

Figure 2 is an enlarged longitudinal side view of the breaker strip showing same in' assembled relation.

Figure 3 is a view in perspective of the breaker strip without side flanges.

Figure 4 is a view in perspective of the breaker strip with side flanges.

Referring more particularly to the drawing, there is illustrated a commercial embodiment of the roof construction in Fig. 1, wherein the plates l0, Hl are each provided with slightly upturned flanges ll, H at their ends extending partly thereacross to provide a means. for preventing rain and snow that might find its way under the breaker strip from reaching the conventional bituminous base material 24 placed below the shingle elements. The bituminous base material 24 is of a length equal to a plurality of spaced metal plates.

The breaker strip I2 is preferably shaped to the configuration and form as shown, and may be formed by a stamping operation by means of dies well known in the art.

In the construction shown in the drawing the breaker strip comprises a series of related planes having the geometrical form of triangles. The planes l3 and M are inclined to the point l5, which is also the high point in the breaker strip. The plane it inclines rearwardly and gradually flattens out into a plane II that coincides with the plane of the shingle element below. The plane I8 inclines forwardly from the plane I6 and is provided with a hooked shaped portion [9 adapted to engage the underside of the base,'the hooked flange 20 of the shingle elements being laterally notched amat 2|, 2| to facilitate the reception of the hooked shaped portion I9 of the breaker strip.

The breaker strip may be provided with lateral side flanges 22 and 23, which act as bearings, and further act as stabilizing means against lateral deflection or distortion.

The vertically upward extending ends or flanges H, H are covered by the breaker strip and the plates ill may be laterally adjusted thereunder to favorably position them below the strip.

Since the operation and purpose of the breaker strip have been described in connection with the description thereof, it is believed that a resume thereof is unnecessary.

The invention disclosed herein is obviously susceptible to various modifications and adaptations without departing from the scope and spirit thereof and it is not intended to limit the invention to the specific construction herein shown and described except as defined by the scope of the appended claims.

What is claimed is:

1. A roof structure consisting of a suitable asphaltum conventional water-proof base material of a length equal to a plurality of spaced metal plates, metal plates longitudinally spaced therealong, an upstanding flange on each end of each plate extending partly thereacross, a metallic breaker strip straddling the contiguous flanges on adjacent plates and having a top surface of a rib on the breaker strip maintained at a substantial elevation above the level of the plates whereby the velocity of snow and ice caused to travel by gravity is retarded in the direction of its movement.

2. A roof structure consisting of a suitable impervious asphalt base-material of a length equal to a plurality of spaced metal plates, metal plates longitudinally spaced therealong, an upstanding flange extending partly across each end of each plate, a breaker strip the aforesaid breaker strip bridging the joint between the plates and the confronting flanges together with a paralleling portion of each plate adjacent said flanges,

. the breaker strip being so configurated that the partly flanged end of each plate may be slightly adjusted laterally thereunder, the breaker strip having a top surface of a rib on the butt end of the breaker strip maintained at a substantial elevation above the plates so that the declination and speed oi downwardly movin: snow and ice is substantially retarded because of the said elevated rib.

3. A rooi structure consisting of a suitable impervious asphalt base-material oi! a length equal to a plurality of spaced metal plates, metal plates longitudinally spaced therealong, an upstanding 10 flange extending partly across each end or each plate, a metallic breaker strip straddling the upstanding flanges and having an ofl-set hooked end portion adapted to maintain the breaker strip against lifting movement from the plates, and having a top surface of a rib on the breaker strip maintained at a substantial elevation above the level of the plates whereby the velocity of snow and ice caused to travel by gravity is retarded in the direction or its movement.
