Claims.

Our invention relates to building constructions and, in connection therewith, to devices for securing covering units to the wall sheathing, or the like. More particularly, the invention is concerned with the provision of a method and means for replacing broken or defective shingles and other covering units on walls or partitions, in which fibre board, or any similar material which has little ability to hold nails, is employed as the sheathing. It will be understood that the terms "wall and "partition are employed herein in a generic sense to denote both inner and outer side walls and walls such as roofs, ceilings, and

the like. g

It has heretofore been proposed to apply covering units, such, for example, as asbestos-cement shingles, to a sheathing of fibre board, and the like. To retain the shingle nails within the sheathing there have been employed locking devices applied over the nail shanks projecting to the rear of the sheathing, the devices positively securing the nails against withdrawal. A construction of this type is described and claimed in our co-pending application S. N. 367,198, filed November 26, 1940. When the wall has been com- 1 pleted, however, the rear of the sheathing be-' comes inaccessible due to the plaster or other interior finish, and such devices cannot be applied to the nails subsequently driven into the sheathing. Hence, if, as frequently happens, shingles are broken or defective shingles are discovered after completion ofthe wall, severe difficulties havebeen met in permanently securing the replacement shingles.

A principal object of the instant invention is the provision of a method and means for installing replacement, shingles or other covering units on a wall of the typereferred to above.

Another object of the invention is the provision of a method of securing replacement units by attachment of the units to previously applied units.

-A further object of the invention is to produce locking clips of a character to inter-engage with an applied unit, the clips including means for receiving and holding nails driven through the replacement units,

Our invention will be more fully understood and further object" and advantages thereof will become apparent when reference is made to the more detailed description thereof which is to follow and to the accompanying drawing, in

which:

Fig. 1 is a perspective view of a wall construction illustrating the application of the method and means of the instant invention;

Fig. 2 is a detail view on an enlarged scale of a portion of the wall of Fig. 1;

Fig. 3 is a sectional view taken as on a line extending vertically through the clip in Fig. 2 with the replacement shingle applied; and

Fig. 4. is a perspective view of the preferred form of locking clip.

Referring now to the drawing, and particularly to Fig. 1, there is illustrated a building wall which, for the purposes of description, has been shown as comprising a fibre board sheathing Ill overlaid with a plurality of covering units suchas asbestos-cement shingles i2. However, the invention is of equal importance where other sheathings having similar properties are used. Also, the invention may be employed to secure like advantages with any conventional or suitable type of covering units laid in overlapping courses. In the wall of 1, it is assumed that a shingle of the middle course illustrated has been found defective after completion of the wall and has been removed, or that for some reason the shingle was omitted in this course during theoriginal wall construction. As will be understood, the instant invention may be employed in any such case and for either individual shingles or courses of shingles or other covering units. Conventional backer strips have been'shown at I4 to underlie the joints between the shingles in the usual manner.

In accordance with the instant invention, a

means is provided to secure the covering unit to be substituted or. to be mounted to cover a shingle space left vacant in the original construction, hereinafter referred to as a replacement shingle, to the previously applied and secured shingles of the next lower course. The upper edge of the replacement shingle is maintained in position by insertion beneath the lower edges of the shingles of the next higher course. The means for securing the lower edges of the replacement shingle comprises, in its preferred form, a locking clip l6, illustrated more in detail in Figs. 2, 4, and 5,

Locking clip l6 comprises a flange is adapted to extend behind a shingle of the next lower course. and an upwardly extending portion 20 preferably integrally connected to retroverted portion "including a right angle shoulder 24 to rest upon the upper edge of the shingle of the next lower course (see Figs. 2 and 3). If desired, the retroverted portion may be extended to provide a portion 26 overlying the front face of such shingle. Portion 20 includes a nail-receiving aperture 21, defined by spring tongues or lips 28 preferably formed from the material of the clip by means of cuts 30. Aperture 21 is of a diameter somewhat lessthan that of the nail to pass therethrough. Retroverted portion 22 also includes an aperture or nail hole 32' in alignment with aperture 21 and of such diameter as to readily receive the shank of the shingle nail. The lower edges of aperture 21 and hole 32 are both in substantial alignment with shoulder 24.v

In mounting a replacement shingle in accordance with the instant invention, clips [6 are positioned on a shingle of the underlying course whose upper edge defines one side of the space left uncovered by the removed or missing shingle.

Flanges l8 are inserted behind the shingle of the underlying course with the shoulders 24 resting upon the upper edge of such shingle- The clips are positioned so that their nail-receiving apertures will be in alignment with nails to be driven through the replacement shingle. In the case of asbestos-cement shingles, or the like, such as here illustrated, and where preformed nailreceiving openings are provided, the clips are so placed that their apertures will be in alignment with such openings. This position may be readily determined in most cases by the nail holes made by the nails used to secure the removed shingle; otherwise the position may be determined by simple measurement, or the like. are in position, the replacement shing'le is applied by inserting its upper edge beneath the overlapping edges of the shingles of the next higher course and nails are driven through the shingle, usually through preformed openings provided for this purpose, as indicated at 50 (see Fig.2), the nail shanks penetrating the apertures in the clip and entering the sheathing therebehind. The tongues 28 defining the aperture yield during the forward movement of the nail inasmuch as the opening between them is somewhat smaller than the diameter of the nail and, upon completion of the driving action, grip the shank of the nail and prevent its withdrawal.

As illustrated particularly in Fig. 3, preferably the nails used are of the barbed-shank type conventionally used for securing asbestos-cement shingles, whereby tongues28 engage behind the barbs to obtain a positive holding action. How-' ever, if a smooth-shank nail is employed, it has been determined that, upon any tendency toward withdrawal of the nail, the resilient tongues 28 bite sufiiciently into the nail to prevent withdrawal under all normal conditions.

The instant invention has been described as particularly applicable to replacement shingles, but it will be understood that the locking clip as shown and described may serve similar functions and advantages with many types of covering units and in other situations where it is desired to secure the lower edge of a covering unit to an underlying member.

Having thus described our invention in rather full detail, it will be understood by those skilled in the art that these details need not be strictly adhered to, but that various changes and modifications will suggest themselves without departing from the scope of our invention as defined by the subjoined claims.
