-- J. 5. BARNETT FASTENER Filed Jan. 21. 1924 BY MZQZAAQTTORNEY Patented Dec. 22, 1925.

UNITED STATES,

JOHN s. BARNETT, OF'OAKLAND, CALIFORNIA;

FASTENEB. 1

Application filed January 21, 1924. Serial No. 687,495;

T 0 all whom it may concern Be it known that I, JOHN S. BARNETT, a citizen of the United States. and a resident of Oakland, county of Alameda, and State of California, have invented a new and useful Fastener, of which the following is a specification.

My invention relates to a device for fastening together the sheathing and studding of concrete forms and the like.

In building the forms for concrete walls, much difliculty has been encountered in securing the sheathing to the studding. This difficulty is due, for the most part, to the fact that the sheathing must be placed on the inside of opposed rows of studs. Usually the space in between a pair of rows of the studding is comparatively small and is crowded with a network of reenforcement, thus making it practically impossible for a carpenter to swing his hammer between the rows. It is therefore one of the objects of this invention to provide a fastener by which the sheathing may be readilv and effectively secured to the inner side of the studs without necessitating that the carpenter have access tothe space between the rows.

Another object of the invention is to provide a fastener of the character described which will permit the form to be readily CllS- mantled after the wall has set.

The invention possesses other objects and features of advantage, some of which, w1th the foregoing, will be set forth in the following description of the preferred form of my invention which is illustrated in the drawings accompanying and forming part of the specification. It is to be understood that I do not limit myself to the showing made by the said drawings and description, as I may adopt variations of the preferred form within the scope of my invention as set forth in the claims.

Referring to said drawings:

Figure 1 is a sectional plan View of a portion of a form for a wall of a building,'showing the fasteners of my invention securing the sheathing to the studs.

Figure 2 is a vertical section of a portion of a form showing the fasteners in position.

Figure 3 is a perspective view of a fastener.

Figure 4: is a perspective view'of another form of the fastener.

In the preferred embodiment of the in- "vention, the fastener comprises a shank 2 formed of round wire and .provided' at one end with a prong?) preferably disposed at substantially right-angles to the longitudinal axis of the shank.

Provided at the other end of the shank is a pair of wings or arms 4 and 5 preferably formed as an integral extension of the shank and comprising portions 6 and 7 The portion 6 extends from the shank at right angles thereto and at right angles to said prong. The other portion 7 is folded against the first portion and is preferably double the length thereof so that it will extend transversely and equally on opposite sides of the shank. It will thus be noted that wing 4. comprises the entire portion 6 and half of the portion 7, whereas the wing 5 comprises the remaining half of portion 7.

In applying the fastener it is laid horizontally upon the upper edge of a piece of sheathing after the latter has been properly set against the studding. The fastener is so held that one of the wings abuts against the inner face of the sheathing While the point of the prong 3 rests against one of the sides 8 of the studs. The prong is then driven into the studding so that the sheathing is firmly held in place. In placing the next piece of sheathing in position, its lower edge is inserted between the stud and the upper wing of the fastener. A fastener is then applied to the upper edge of the sheathing 1n the manner previously explained.

To remove the fasteners it is merely necessary to run a wrecking bar along the side of the studding thereby causing the prongs 3 to be withdrawn from the stud and conse quently freeing the sheathing and studs from each other.

If desirable the shank may be formed as shown in Figure 4 with an offset portion 13 which permits of the ready insertion of the wrecking bar between the stud and shank.

I claim: v

1. A fastener of the character described comprising a shank; a prong extending substantially at right angles from one end of said shank; and an extension at the other end of said shank comprising aportion extending at right angles from said shank and at right angles to said prong, and a portion folded upon said first portion and extending transversely of the longitudinal axis of the shank in substantially opposite directions.

2. A fastener of the character described formed entirely of one piece of wire and comprising a shank formed of'an intermedlate portlon of said piece of Wire, a prong formed of an end portion of said pieceandextending transversely from one end of' said shank, and a head extending transversely from the other end of said shank and formed of a second intermediate portion and the other end portion of said Wire.

3. A fastener of the character described comprising a shank having an'ofi'set portion located intermediate the'en'ds. of the shank and adapted for the reception of a tool, a prong extending transversely from said shank at one end thereof, and a head eXtend-' my hand at Oakland, California, this 28th day of December, 1923.
