PATENT OFFICE.

WIBE-FASTENING DEVICE.

-Application led ApritS,

My invention relates to wire fastening devices, and particularly to means for support- A ing a plaster ground fabric or the like upon the framework of a building, in the formation of walls, floors, ceilings, etc.

In connection with the formation of walls,

etc., by applying stucco to a wire mesh or metal lath structure, themesh or plaster ground, as it is called, is usually nailed to the studding or sheathing, and it is desirable to support the plaster ground in a plane spaced from the plane of the studding, so that the metal of the plaster ground Willbe completely imbedded in the stucco material. Various methods have been employed for accomplishing this purpose, as by applying a spacing element tol the shank of a securing nail, at a point intermediate the ends thereof, so that the mesh will be caught between the head of the nail and the spacing element when the nail is driven into the studding, and held from the studding by the spacing ele ment.

My invention has for some of its objects the provision of an improved form of spacing member which will permit of more complete embedment of the wire mesh or other plaster ground, than in the cases of some of the devices heretofore employed; Which is cheaper to manufacture; which will not bind the wire strands in such manner as to prevent longitudinal movement thereof, and which will yield when the securing nail is driven home, thusv allowing a movement of the house frame without straining the stucco or plaster after it has been applied to the metal 'backing or fabric. v

Another object of my invention is to provide a nail having means formed theeron for holding a Wire strand against movement from beneath the head of the nail, and means for retaining a spacing memberupon the shank of the nail.

Some of the forms which my invention' may take are shown in the accompanying.H drawing,wherein Figure l is a fragmentary view showing plaster gronnd structure secured in position by the use of my device; Fig. 2 is a horizontal sectional view of a portion of the structure of Fig. 1, on an enlarged scale, and with the securing nail partially driven to its holding position; Fig. is a similar view showing the nail driven home; Fig. 4 is a partial sectional view., on an enlarged scale, showing the manner `1927. Serial No. 182,013.

which the spacing element is held on the nail previous to driving of the nail; Fig. 5 is a perspective view of the nail, and Fig. 6 is a cross sectional view of a nail, looking from beneath, and showing vthe spacing element and strand wire in assembled relation thereto.

For convenience of description, I have shown the spacing element as employed in connection with a paper back fabric, similar to that shown and described in my Patent No. 1,502,012, issued. July 22, 1924, but it will be understood that the paper backing is not 'an essential element of the invention, and that other reinforcing elements, such as expanded metal, may besubstitutedl for the wire mesh shown in the drawing.

The plaster ground structure shown in the drawing comprises a wire mesh structure having stay wires 5 and strand wires 6. The

strand wires are provided with bends 7 that I protrude through the paper backing 8, which is held in place bytie rods 9, that lie within .said bends and against the rear surface of thc paper 8, somewhat after the manner described in my patent referred to. The bends 7 may serve as spacing elements, when placed against sheathing or so positioned as to lie against studding, but by the use of the device hereinafter described, I am not dependent upon these vbends for spacing of the fabric from the studding.

The plaster ground structure is secured to studding l0 or the like by nails 11 that are driven into the studding until their heads engage the wire mesh. The spacin element consists of a coil of wire 12, whic may be wrapped around the shank of the nail, or which may be preformed and placed on the nail. In applying the nail 11 and the-spacer 12, the nail may be forced through the paper backing 8, atia point below one of the strand wires 6, and the spacer 12 turned so'that its out-turned end 13 will partially surround the Wire 6, when the nail is driven into the studding in the manner shown in Fig. 3.

The shank of the naill' near vits point is shown as provided with lugs or burrs formed thereon by suitable dies and which are en-V gagpd by the turns of the spacing element 12 to old such spacin element upon the nail and also to temporarily hold it in position adjacent to the point ofthe nail so that the nail can be readily grasped by a workman, and the strand wire slipped into place, as shown 1n Fig. 2. This arrangement insures that the spacer will not interfere with the handling The head of the nail isdished slightly as *i shown more clearly in Fig. 4 and is provided with protuberances 11a that are preferably formed thereon by the dies that are employed in forming the nail. When the nail has been driven home, at least one of these protuberances will engage-tbe Wire to hold it against the shank of the nail and prevent it slipping from beneath the head of the nail, thereby assisting the out-turned end 13 of the spacer in holding the wire 6 in position beneath the head of the nail. This is an important feature of my invention because diliiculty is always experienced in preventing the wires from being pulled from under the nail heads, particularly during manipulation of the fabric structure in applying the same to studding orother supporting framework.

, The Wire from which the` spacer l2 is formed is preferably circular in cross section, so that it has approximately only point contact with the strand wire 6, and will therefore permit of substantial complete imbedment of the Wire 6 in the stucco or cement. Furthermore, it has no corners that tend to cut or nick the wire 6, is yieldable to permit slight movements of the Wire 6, and also reduces the tendency of the nail head to flatten the 'strand wire, in case the nail is driven too deeply into thel studding. There is also less tendency for the inner end of the spacer 12 to be driven into wooden studding, thus making for more uniform spacing of the plaster ground from the studding.

A I claim as my invention 1. A wire fastening device comprising a nail, a spacing coil surrounding the shank of the nail, and studs on the shank of the nail in position to be engaged by said coil.

2. A wire fastening device comprising a nail, a spacing element having a plurality of turns about the shank of said nail, and a stud on th shank of the nail in position to be engaged y turns of said spacing element.

3. `A wire fastening device comprising a nail, a spacing device mounted on the shank of said nail, and having a portion extending transversely and rearwardly in position to engage one side of a wire, and a stud on the forward or inward side of the nail head for engaging the other side of said wire.

4. A wire fastening device comprising a nail, a spacing element mounted on the shank of the nail, means adjacent to the point of the nail for limiting movement of said element longitudinally of the nail, and a wire engag- 0 ing stud on the inner surface of the nail head. In testimony whereof I, the said EDWARD L. BENEDIo'r, have hereunto set my hand.
