JOSEPH M. THORPE, OF SAN FRANCISCO, CALIFORNIA.

Application filed May 19,

The invention relates to improvements in lath spacers or turring'nail, particularly for use in spacing metal lath or wire netting a suitable distance away from a wall or surface to which a coating of some .plaster composition is to be applied.

One object of the invention is the provision of a fur-ring nail in which the spacing ele ment is so formed that the paper usually put upon the wall, especially in stucco construction to prevent entrance of exterior moisture, will not be injured, and that the metal lath will be securely held and locked into a groove formedin the cap portion of the spacer. V

Another object of the invention is to provide the body portion of a spacing element with a flanged opening having a mouth adapted to be in a firm engagement with a nail in all possible angular positions of the nail relative to the body portion, thus mak ing it immaterial whether the nail is driven through the opening so as to be in a preterred right-angular position relative to the body portion or whether the nail is driven obliquely through the body portion, and thereby also making the nail applicable to the spacing element, and the latter applicable to a wall sheathing even by unskilled hands.

A further object is the provision of a lath spacer in which the spacer may be easily slid into position under the lath without raising the lath by hand. The spacer will conform to the angle at which the nail is driven and this angle may be so determined that in driving the nail the spacer will adjust itself, thus tensioning and spacing the wire at the same time.

With the foregoing and other objects in view, which will appear in the description, my invention residesin the construction and arrangement of parts hereinafter described and more particularly claimed, although I.

wish it to be understood that changes and details of construction may be made within the scope of the appended claims and without departing from the spirit of the invention.

Preferred embodiments of the invention are shown in the accompanying drawings, in which- I Figure 1 is a perspective view of oneembodiment of the improved lath spacer, provided with a groove across the cap portion thereof and with legs extending from the FATE . rename NAIL.

cap and having curved flanges thereon for seating the spacer upon a wall sheathing;

In the drawings, the reference numeral'l, indicates the usual nail by; which a lath which are contemplated.

.ing of the wire netting numerals 2, 3, 4: and 5 indicate the body of the various modifications of the spacer ent modifications of spacers are constructed of sheet metal and are formed with a substantially rectangular cap or body portion 6, which has therein a transverse groove 7, and in each body portion and virtually centrally of the groove is an opening 6,1preferably formed by a flange 9, which extends inward from the body portion and at its junction therewith isof a round formation and of a circumference adapted to accommodate the shank of a respective nail 1 therein. Preferably at three virtually equidistant points 10 of this rounded. portion the inward extension of the flange is substantially at right anglesto the body por-- tion,

while at intermediate points the flange tapers so that the mouth of the opening 8 is virtually of a'triangular shape, the sides of the triangle being indicated by the numeral 11 in Figure 9. By this construe tion the spacers are adapted to accommodate nails of different diameters, so that, even if a nail fits only loosely within the round flange portion of a spacer, the sides 11 of the flange will press on the nail driven into the spacer and firmly hold the nail in engagement therewith in various angular positions of the nail to the body portion, as shown in Figures 5, 7, and 8.

In Figures 1, 4, 5, 6, 7 and 8,the body portion 6 is shown as having at each end and onrits outer side a projection 12 formed in any suitable manner. These end pro ections are adapted to be hooked between a wall 13 and a portion 14 of a wire netting, as. shown in Figures 3 and 4, before the respective spacer is placed in position for the fastenthereto, and they serve as means for preventing the wire from sliding off the body portion before the wire is guided into the groove 7 and against the shank of the nail l. Legs 15, each preferably provided with stifi'ening flanges 16 at its side edges, extend" at virtually right angles from the body portion, which in the forms shown in Figures 1, 2 and 3 is somewhat longer than in tl e forms shown in Figures 4, 7 and 8, the projections 12 in the latter figures being spaced only 'sufliciently far from each other for receiving the head of a nail 1 between thenu r In Figures 1, 2 and 3 eachofthe legs 15 is shown as. having at its end edge a somewhat arcuate seating flange 17, the ends of which are curved toward the body portion 6, as shown at 18, and this flange is preferably shorter than the body portion. A spacer thusconstructedis easily placed in position upon a wall without being liable t injure the insulation paper 19', with. which All of the differ-' Figure 4. By this construction a tensioning means for the wire netting upon the spacer is also provided, and the spacer is allowed to adjust itself to any angle at which the nail may be driven.

and the flanges being of virtually the same length as the body portion 6. Because of their short body portions 6, the spacers 4 and 5 may be easily tilted endwise for spacing a wire netting from a wall, but it is obvious that they may also be tilted sidewise for the same purpose. In this connection it should be observed that, when the spacers are tilted endwise, the width of the flanges 20 is sufficient for preventing the flanges from digging into the paper on the wall. Furthermore, the insulation paper is of an oily nature so that the flanges easily slip over the paper, whether the spacers are tilted endwise or sidewise, without cutting or tearing the paper and thus allow the'spacers to be readily placed in their wire-engaging at right angles to the body portion, so that the spacer has only one projection 12 and that each of the legs 15 has a stiffening,

flange 16 only at one side edge, and the spacer 5 shown in Figure 6 is similiar to the spacer 1, except that the spacer 5 is cut off virtually squarely at one end adjacent to the groove 7, so that, like the spacer 3, the

spacer 5 has only one projection 12 on its body portion and only one flange 16 on each leg 15. On account'of their reduced length the spacers 3 and5 are particularly adapted'to be secured near wall corners or in other. places where there is insuflicient room for fastening either of the spacers 2 and 1. v

"It evident that the lath spacers de scribed in the foregoing are simple in construction and. eflicient in application and that the desired spacing and tensiouing of a lath may be accomplished quickly and easily by means thereof. 7 i a It is also evident that the projections 12 on each spacer, besides serving as means, for guiding the wires 1% into the groove 7, aid in distributing the force of the hammer blows, when the nail 1 is being driven home through the. spacer and into a wall 13. In addition,-it should be observed that, when the wires are thus held by the nail head in the Wall is usually covered, as shown insharp-edged ribs 21, which are usually" formed on the inner side of the nail heads, can not cut into the wires so deeply as to cause their severance, which could result if the body portions 6 of the spacers were not grooved transversely.
