United States Patent FINISHING STRIP FOR ROOF EDGE Thomas Pelican, 301 S. Howard St., Spokane, Wash.

Filed Apr. 21, 1955, Ser. No. 502,836

1 Claim. (Cl. 5067) The present invention relates to improvements in finishing strips for the lower edge of a roof. In finishing a roof on a dwelling, it is the practice to box in the projecting portions of the rafters Where they extend out beyond the side walls of the dwelling. In order to provide the necessary air vents to permit air flow upwardly from the eaves beneath the roof and thus avoid execessive heat beneath the roof, vents have been provided and these vents usually are placed in the horizontal plates that extend beneath the rafters.

It is desirable also where the roofing employed is of a gravel and tar type to have a finishing strip at the lower edge of the roof to protect the roofing at this point. It is the purpose of my invention to provide a novel construction whereby the necessary vents for admitting air at the lower edge of the roof and the protective metal strip may be combined in such a way as to improve the air vent structure to make it more safe from a Water or moisture admission and to additionally support the metal strip which protects the roofing at the lower edge.

The nature and advantages of my invention will appear more fully from the following description and the accompanying drawings illustrating a preferred form of the invention. It should be understood, however, that the drawings and description are illustrative only and are not intended to limit the invention except insofar as it is limited by the claim.

In the drawings:

Figure 1 is a fragmentary perspective view looking at the roof edge from the inside and illustrating the facing plate, the roofing, the sheathing, and other elements which are used together at the lower edge of the roof;

Figure 2 is a sectional view taken parallel with a roof rafter through the lower edge of the roof; and

Figure 3 is a face view looking at Figure 2 from the left.

Referring now to the drawings, my invention is shown as applied to a roof wherein the rafters are indicated by the numeral 5, the sheathing over the rafters is indicated by the numeral 6 and the roofing material over the sheathing is shown at 7. The lower edge of the roof is boxed in by using a face plate 8 across the ends of the rafters and a bottom plate 9 which extends from the face plate to the side wall 10 of the building.

According to my invention I provide the face plate 8 with air passages 11 at spaced intervals between the rafters 5. These air passages will permit air to pass through the face plate beneath the sheathing 6 and upwardly along the roof. It will also, however, permit moisture and trash to blow into the space over the bottom plate 9. In order to protect against this contingency and at the same time protect the lower edge of the roofing material 7, I provide a metal strip 12 which is shaped as illustrated in the drawings to have a mounting flange '13 that is adapted to be nailed to the sheathing 6. Adjacent to the flange 13, the strip 12 has a head 14 which forms a stop for the lower end of the roofing material 7 to keep it from being eroded away by natural weather.

conditions. The metal strip 12 has a depending face portion 15 to provide a drip face over which water can drain down and away from the face plate 8. A flange 16 is formed at the lower edge of the face portion 15 and extends upwardly and inwardly to bear against the face plate 8. Preferably the angle between the face portion 15 and the flange 16 is an acute angle, sharp enough to cause the flange 16 to lie above a plane perpendicular to the face plate through the lower edge of the strip 12.

The flange 16 is provided with a plurality of apertures 17 which will permit air to flow up into the space between the strip 12 and the face plate 8. Thus the strip 12 and its flange 16 cooperate with the face plate 8 to provide a tortuous air passage to the space beneath the sheathing 6 between the rafters 5. The flange 16 may also be provided with small apertures 18 along its lowermost portion where it joins the face portion 15 in order to drain out any water that might enter through the openings 17. However, in view of the angle which the flange 16 makes to the horizontal and the fact that it is shielded by the face portion 15 of the strip 12, there is very little opportunity for water to enter the opening 17.

It is believed that the nature and advantages of my invention will be clear from the foregoing description.

Having thus described my invention, I claim:

A finishing means for the lower edge of a roof having supporting rafters, sheathing secured to the top edges of the supporting rafters and roofing material mounted on the upper surface of the sheathing, comprising a face plate extending downwardly from the roof edge secured to and abutting the outer ends of the rafters, said face plate having air passages therein adjacent to the sheathing, and between the rafters, a strip having a mounting flange secured to and overlapping the upper surface of the sheathing at said lower edge, said strip comprising a bead abutting the lower edge of the roofing material, a depending face portion joined to said mounting flange by said head and diverging downwardly away from said face plate, said strip also comprising a flange extending from the lower edge of the face portion inwardly and upwardly to the face plate and bearing against the face plate, said last named flange having apertures therein for admission of air, certain of said apertures being along the lowermost portion thereof.
