' FUR/RING- AND FASTENING DEVICE.

Application filed. January 16, 1925.- Srial No. 81,639.

such projection and the spacer after thedevice has been driven into position.

An object of the invention is to provide the device with a spacing member which will not spread or flatten on wall when force-d thereagainst and thus insures a uniform and predetermined spacing of the netting from the wall. w

Another object is to provide the device with a spacing memberwvhichwill have a bearing surface of maximum area and.

smoothness wherebymutilation of the surface to which itisapplied may be prevented.

A further object of the invention is to provide a device of the character described with which plaster will readily become keyed when applied thereover.

A still further object of the invention is to provide the dev ce with a spacing member which will interfere to a minimum eX- tent with the direct keying of the plaster to the netting. v

The invention possesses other objects and features of advantage, some of which, with 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 'lTOl'D'lll'Ig part of the specification. It s to be understood that I do not limit myself to the showing made by the said drawin s and description,

as I may adopt variations of the preferred, form within the scope of my invention as set forth in the claim.

Referring to said drawings:

Figure 1 is a perspective view of one em.- bodiment of the device of my invention.

Figure 2 is a plan view of a blank used in forming the spacing member of the device shown in Figure 1.

Figure 3 is a fragmentary sectional view of a wall showing devices operatively positioned thereon both before and after being driven to final position.

with one face 17 resting thereagainst.

Figure 4 is a perspective view of another embodimentof the device.

The operative application of most of the heretofore used devices of the class to which the present invention relates has presented certain difiiculties which have prevented a more wide-spread use of such devices. Thus,

it ,is desirable and customary to drive the.

l'a teners to place with a single blow of a heavy hammer, but most of the before mentioned devices, if the hammer blow be the least bit excessive, have tended to flatten out or to be driven into the sheathing so that the netting has either been spaced too close,

to the wall or is unevenlyspaced therefrom, thus making difiicult the placing of a plaster coat on the netting such as will have a uniformthicknessand smooth exterior surface. On the other hand, the fasteners having spacing portions so formed that they cannot be flattened or driven into the wall, have usually prevented the keying of the plaster to the netting immediately adjacent their point of contact with the netting. In accordance with the present invention, however, a fastener spacing member is provided which will neither'be flattened out or driven into a wall and, which will at the same time present a minimum portion thereof against the net-ting.

The embodiment of my invention shown in Figures 1 to 3 inclusive comprises a fastening unit 7having a nail portion 8 provided with a point 9 at one end and a wire engaging head 11 at the other end( As here shown, the head His of circular form and is relatively large so that it may engage one or more strands of a wire netting 12 between itself and a suitable spacing or fur-ring mem-' her.

Since, as previously pointed out, it is esirable that the spacing member present a 7 large base to the'sheathing 13 and have a comparatively small contact with the net- 14 is formed as though of a piece of tubing of triangular section placed with its axis parallel to the surface 16 of the'wall and The face 17, it will'be noted, is provided with a perforation 19 arranged to receive the shank 18 of the nail 8 which also )asses through a suitable opening 21 provic ed at the top edge or corner 22 of the member 1a and against which the netting 12 is arranged to be held seated by the nail head 11.

As here shown, the member 1 1 is of unitary structure and is formed by a suitable bending to shape, of a blank 23 having parallel end edges 24f and 26. It will be noted that tac perforation 19 is provided in the center portion of the blank which forms the face 17, and that the

edges

24 and 26 are each provided with segmental perforations, so that when the shank is positioned in the perforation 19 and the

end portions

27 and 28 of the blank have been bent from the edges of the vportion 7 to bring the outer edges there-of into juxtaposb tion, the opening 21 will be defined about the nail shank by the segmental. perforations and the

edges

24 and 26 will together define the spacing member bearing edge or corner 22. To insure against undue relative movement of the

edges

24 and 26 before and during the positioning of the fastener, the portion 27 is preferably provided with tabs 29 which may be bent down over the edge of the portion 28 as hereinshown, but it will be particularly noted that when the nail head is in position to hold the netting tioned and held near the nail point when the fastener unit is assembled, handling of the fastener as a unit thus being made possible. It will also be noted that the tabs 29 project above the corner 22 and are preferably so spacedapart that the nail head when driven against the spacer will bear thereagainst to thereby imprison the netting between itself and the edges 24': and 26 without undue pressure on the netting strands.

In the embodiment shown in Figm'e 4, it will be noted that the upper 'nail'opening 21 is rectangular rather than circular, so that the nail may, if desired, be angularly disposed with respect to the'top edge 22. In this i'nanner, the nail may be primarily in.-

serted to slant toward a portion of wire to be stretched and then straightened up as,'or before, it is driven, to thereby stretch the wire.

I claim in a device of the character described a spacing member comprising a triangular tube formed of a strip of sheet metal with the ends recessed and abutting at one of the corners, a fastener comprising a pointed and headed shank passing through the said spacer recesses and the side opposite said end of the shank whereby it may lie against the wall when the device is operatively disposed, and .means incorporated with the spacer for holding the strip ends together. In testimony whereof, I have hereunto set my hand at Oakland, California, this 12th day of January, 1926. I
