NAIL

Filed Deo. l5. 1926 lll/l FICE- E- INVENTUH Patented Nov. 26, 1929 ROBERT H. BUCK, OF ALAMEDA, CALIFORNIA NAIL Application med December 1e, 192s. serial No. 154,352.

My invention relates to nails useful as .furring devices usually employed to maintain a screen spaced from a Wall for the reception of plaster, and relates especially to furrmg devices adapted to be installed at intervals on a Wall to support and position the ad]acent screen.

An object of my invention is to provide a nail which forms a simple'and effective furring device.

.Another object of my invention is to provide a furring nail which will grip firmly the material to be supported. l

An additional object of my invention is to provide a furring-deviee in which the gripping action is effected simultaneously With the action which drives the device into the support.

My invention possesses other advantageous features, some of which with the foregoing', Will be set forth at length in the following description where I shall outline in full/ that form of the nail of my invention .which I have selected for illustration in the drawings accompanying and forming part of-the present specification. In said drawings I have shown one form of nail embodying my invention, but it is to be understood that I do not limit myself to such form since the invention, as set forth in the claims, may be embodied in a plurality of forms.

In the drawings:

Fig. 1 is a plan view showing oneform of thel furring nail of my invention in use.

l Fig. 2 is an elevation of a modified form of nail.

Fig. 3 is a plan view of the nail shown in Fig. 2, a'pair of wires being shown in gripped position.

Fig. 4 is-an elevation of a second modlfied form of the nail.

Fig. 5 shows the form of nail of Fig. 2 as it is utilized on a support such as a wall, the nail being in elevation and the remainder of the view being in cross section.

45 My invention preferably comprises a nail having lips formed by turned down portions of the nail head, the lips preferably cooperating with a spacer to grip the body to be supported. l y

l With the increased use of stucco construction for buildings, it has become customary to aiiix the plaster by-means of Wire lath or screen secured to the Walls of the building. In order to provide a firm hold for 'the plaster on the screen or metal lath it is essential that the lath be spaced somewhat from the solid backing of the wall. Various types of spacing devices have been used from Wooden furring strips which are nailed to the wallv and in turn support the lath or screen to sundry metallic devices which space the screen from the'wall and hold it with the cooperation of securing devices such as nails. Most furring devices either require a preliminary application of spacers prior to thepositioning of the metal lath and an additional application of supporting members to hold the lath on the spacers or are otherwise complicated in handling or manufacture. My furring device can in a single operation be fixed to the wall and firmly clamp the wire screen orv lath to be supported.

In the preferred form of my invention I preferably provide a nail having a shank G of the usual kind which ispointed at one end as at for convenient driving into a support such as a wooden stud 8. At the opposite end of the nail, a head 9 is provided. The head is preferably a plane or disc forming an integral portion of the shank 6 and is disposed perpendicularly thereto. The disc is of relatively thin metal and is advantageously of circular contour. To provide vmeans, for gripping a body to be supported, such as the strands 11 of metal lath'or screen used in stucco construction, I preferably bend or otherwise deform portions of the leriphery of the relatively thin head 9 of t e nail and cause them to lie substantially at right angles to the main portion of the plane `head 9.

These downturned portions form lips 12' which lie substantially parallel to the shank 6 ofthe nail. The lips 12 may be of any desired number. In Fig. 4 I show 'a form ofl nail (having. but one lip, while in Figs. 2, 3 and 5 I show a preferred form of nail having two, equally spaced peripheral lips l2. In Fig. 1,' I have shown a three lipped' furring nail in use with a metallic screen sometimes termed chicken wire.

In order to form a firm seat for the lips 12 and also to space the metallic screen the` re uisite distance from the wall 8, I have provided a collar or spacer 13 preferably made 5 of compressible or fibrous material, such as felt, or gun Wadding. The vspacer 13 is preferably an annulus which is slidable' upon the shank 6 of the nail, and is placed on the naii prior to the driving of the nail into the supmport 8. When the nail is driven home, the

lip or lips 12 engage the spacer 13 and compress it slightly, thereby forming one or more tubular passages in which the Wires 11 are firmly held. 15 While the nail of my invention can be originally formed in the shape shown in the drawings, it is also possible to' take standard nails having flat, thin heads, usually termed roofing nails, and by'deforming peripheral gg'portions of the heads, manufacture nails of the type shown herein.' With the addition of a collar or spacer of felt or similar material, an excellent furring device is provided. It will be appreciated that with the device of my invention, the metal lath or screen is firmly supported ata definite distance from the support and is tightly gripped in place. The blow of the hammer which drives the shank of the nail into the support is also suiiicient to force the lips of the head against -the spacer andl cause .the wires to be tightly grasped and firmly held in place.

Although. the nail with the single lip `may be used, as shown in the upper portion of Fig. l, I preferably use a nail having' two or more lips as the` head is then supported equally Well on both sides of the shank. The nail with a plurality of lips is le'ss liable to become bent due to one lip'striking the spacer 40 or the support and cooking the head at an angle. v I claim:

.1. A nail comprising a shank, and a relatively thin head mounted perpendicularly on the end of said shank, peripheral portions only of said head being turned toward said shank. Y

2; A furring device comprising a nail havin@r a shank and a relatively thin, plane head substantially perpendicular to. said shank; k and ay lip formed by a portion of said head bent toward said shank.

3. A furring device comprising a nail having a shank, a relatively thin fiat head there- 55 on substantially at right angles toil-said shank; a liplformed on a portion of said head, said lip being substantially iat and parallel to sai shank; and a'spacer slidableon said p shank, said spacer being substantially larger thansaid thin Hat hea In testimony whereof, I haveI hereunto set my hand.
