Patented June 9, 1953 ROOFING RETAINER Homer 0. Young, Milwaukee, Wis. Application January 21, 1949, Serial No. 71,993

The present invention relates to roofing and the like and more particularly to retaining or fastening means for roofing sections or shingles.

An object of the invention is to provide an improved roofing retainer for preventing lifting and tearing of roofing sections or shingles by wind action, and which can be easily, quickly, securely applied to both old and new roofs.

Another object is to provide a roofing retainer of this character which is adapted for insertion in shingle slots and which will avoid interference with roofing nails.

Still another object is to provide a roofing retainer which can be firmly anchored in place without hammering or otherwise injuring the weather surface of the roofing.

A further object is to provide a roofing retainer of simple and durable construction which is capable of inexpensive manufacture.

A still further object is to perfect details of construction generally.

The invention further consists in the several features hereinafter described and claimed.

In the accompanying drawing, illustrating certain embodiments of the invention,

In the drawing, l designates a board roof on which successive overlapping courses of roofing sections it, here shown to be shingle strips, are by nails ii in the usual manner, the shingle strips being formed of the usual asphaltic composition and having the usual mineral sur- I The lower edges of the shingle strips in the successive courses are disposed approximately at the upper ends of the slots in the immediately underlying strips,..and the -shingle portions or .tabsflilarie approximately.centered with respect 4 Claims. (Cl. 108-33) to the slots of the underlying strips. In roofing of this type, StIOIlg wind action has a tendency to lift the shingle tabs and to cause weakening, tearing and failure of the roofing.

The roofing retainer or clip shown in details in Figs. 2 to 6 is designated generally by the nuineral 2i and comprises a piece of weather-resistant resilient sheet metal bent to form a substantially flat rectangular base plate 22 and an outwardly offset spring tongue 23 projecting up- .wardly from the middle of the upper edge portion of the base plate, the tongue including a shoulder-fanning portion 25 joined to and projecting approximately at right angles to the plane of the base plate, and the outer portion of the tongue converging forwardly toward the plane of the base plate and having a slightly rounded front end. The tongue 23, which extends from a long edge portion of the base plate, is considerably narrower than the length of the base plate, and the width of the tongue is slightly less than the width of the slots i9 in the shingle strips. The attached end of the tongue shoulder 2 1 has a junction with the base plate at a point set inward from the long upper edge of the base plate, thus forming a central notch 25 in the upper edgeof the base plate, the retainer blank being slit, as seen in Fig. 6, to provide this relation. The base plate is thus provided with spaced upper edge portions 26 which project upwardly from the tongue shoulder at opposite sides of the tongue. The base plate is ins-ertible between superposed shingle strips and is engageable with the underside of a shingle strip at opposite sides of a slot in the strip. Prongs or shoulders 27 are struck up from the base plate near opposite sides and are adapted to engage and become embedded in the bottom surface of the overlying shingle strip. The long lower edge of the base plate .ners of the base plate and of the tongue end are also forms a shoulder for this purpose. The corbroken or rounded to facilitate insertion of the retainer.

As seen in Fig. 6, the shingle retainers can be formed from a sheet metal strip with very little scrap, successive T-shaped retainer blanks extendingtransversely across the strip in opposite directions with the tongue portion of each blank between the side edges of the base plates of adjacent blanks.

In applying the retainer to the roof, which may be either an existing roof or a new roof, the retainer is grasped by the tongue 23 and opposite ends of the retainer base plate 22 are slid upwardly under adjacent shingle tabs 29 at opposite sides of a slot IS, the tongue being moved upwardly in the slot to bring the tongue over the middle of the shingle tab at the upper end of the slot and to bring the tongue shoulder 24 against the lower edge of the latter shingle tab, as best seen in Figs. 2 and 3. The wide v pronged base plate 22 engages and becomes firmly embedded in the under surface of the overlying shingle strip or section, this surface being .free of mineral surfacing. The resilient tongue 23 engages and presses downwardly over the mineral-surfaced weather face of the shingle tab in the superposed course, thus holding this tab in position against lifting by wind 'action. The tongue does not penetrate or tear the mineral-surfaced shingle tab, thus avoiding weakening and deterioration of this tab. The upper edges 26 of the base plate extend under the slotted shingle strip above the upper end of the slot, thus improving the engagement. However, the character .and position 01 the base plate is suchthat the retainer is easily inserted, there being no interference with the shingle-securing nails H. The wide base plate also resists swivellingand shifting of the retainer, and distributes the pressure on the overlying shingle. The narrow-tongue, however, minimizes lodging of leaves anduother. debris.

The modified form of shingle retainer 3| shown in 7 is similar to that of Fig. 4 except that the sheet metal member 2| of Fig. 4 is partially or completely covered with a thin coating 28 of protective and adhesive material, such as asphalt. When the retainer is applied to the roofing this coating-will adhere to the shingle surfaces, particularly after being warmed by solar or artificial heat. 1

It is also desirable to provide shingle retainingmeansv at the edges of the roof. A roofing clip or retainerlLsliown in detail in Figs. 8 and 9 is suitable for this use. This clip or retainer comprises .a piece of weather-resistant resilient sheet metal bent to form a substantially fiat rectangular base plate a2 and a reversely bent spring tongue 43 spaced above the base plate, .thetongue converging toward the plane of the base plate and having a shoulder portion it attached .to the .baseplate. An upstanding flange 45 is-formed along .a long edge of the baseplate to engage an edge of theroofing, and the tongue shoulder projects .fromthe middle portion of this-flange and lies in the plane of the flange. i

The base plate is provided with struck-up prongs or shoulders 41 to engage and become embedded in the underside of a shingle for resisting withdrawalof the, retainer. The retainer 4! embraces :theedge portions of two superposed shingle strips, the base plate engaging the underside of the lowenshingle strip and the roofing tongue .43 engaging and pressing down a tab 20 of :the upper shingle-strip, as seen in Fig. 8. The retainers M can be made from a multiple blank generally similar to that of Fig. 6.

In each form of the retainer the sheet metal member may be formed wholly of a rust-resistant metal or it may be formed of steel with a rustresistant plating or coating.

The shingle retainers of the invention are also applicable to siding, and the term roofing as herein used includes siding.
