FURRING AND FASTENING DEVICE.

Application filed Gctober 27, 1924. Serial No. 746,007.

My present invention is an improvment on the invention of the patent issued to me May 15, 1923, No. 1,455,253, entitled Furring and fastening device, and differs therefrom by the addition of'a driving head that rectifies the tendency of the staple-leg to bend ou"-of-line,' or out-of-plane, or both, when 1 being driven home and into other than soft or straight-grained wood.

Previous to the use of the invention of my patent above, and still in sections of the country, a very common method of anchoring plaster to the exterior walls of bungalows and buildings, is by laying wiremesh lathing over vertically positioned wooden furring strips spaced about eight inches apart and nailed over building paper to the sheathing of the building. Plaster is then spread over the wall surface and around the wooden furring strips. The strips bedded in the wet plaster soon absorb moisture and swell. As the plaster dries, the strips shrink more or less and unequal stresses are set up -in the wall, resulting, upon close examination in fine hairlike cracks throughout the wall. These cracks tend to become longer and wider as the annual seasonal changes take place, and eventually patches of plaster dropoff.

An important object of my invention is the provision of an improved staple with an outstanding driving head to overcome the above initial fine cracks and thus extend the life of the wall to a very marked degree, and to present a uniform and continuous surface of plaster. Other important objects of the furring device are: The quick and true application of it to-any kind of wood sheathing and building paper; to efiect a strong holding power; to effect a uniform outstanding distance from the sheathing surface; and to efi ect ease of application of the wire lathing over and to the bearing surface of the staples.

I attain the above objects by the general formation of the staple and the manner 0 applying it to the wall as illustrated in the accompanying sheet of drawings, and in which:

f to the top.

Figure 1 is a side elevation of the staple.

Fig. 2 is a view of the staple in its normal position on a wall and supporting the building paper-thereunder and the wire lathing thereover; the wall, paper and lathing being shown in section. Fig. 8 is a view in elevation of a section of wall in three stages 'of construction for the plastered wall.

Throughout the figures the numeral 1 represents the prong of the staple, 2 its driving'head, 3 the shouldered stop-surface or first hump, and 4 the outstanding supportting or bearing surface of the device, and

the latter may be considered the second hump of the staple. The staple is preferably made of steel wire and formed with a ,wide mouth; the prongs thereof being pointed and sloping inwardly a little to ef feet the proper draw of the staple when driven into the wood.

The driving head is formed as a part of the first hump by a definite upstanding section of wire recurved or bent back upon it self, resultingin a reinforcedhead easily seen and struckby the workman; thus, the head insures a means for the quick and ,true driving of the staple-leg in the plane of the staple. The outstanding portion 4.- may join the shoulder portion 3 with a blunt curvature to eliminate corners and to prevent the wire lathing from catching thereat.

In'Figs. 2 and 3, 5 represents the building sheathing, 6 the building paper, 7 the wire lathing and 8 an ordinary staple holding the lathing on the second hump or supporting surface 4 of the staple.

In Fig. 3 the building paperG is shown positioned on the wall and held thereon by contact with the first hump or shoulder 3.

of the staple; also a section of wire lathing is shown supported on the bearing surface 4 of the second hump of the staple, and 9 represents the plaster or cement, the finished wall bonded and held firm and stable by the wire lathing and staple reinforcing elements.

In operation, the first step is to lay the building paper on the wall. This is accom plished by unrolling and laying the paper thereon longitudinally and starting at the bottom. The next strip is then laid partially overlapping the previous one, and so on The overlapping is for the purpose of shedding the moisture and water away from thewood sheathing. The paper is secured to the sheathing by my staples,

which are preferably positioned vertically and in staggered relation on the wall and driven therein until the shoulder 8 contacts the paper. The papered wall may now receive the wire lathing at any time.

The wire lathing is laid from the top down, and is unrolled upon the surface of the outstanding staples, positioned and stretched downwards, and secured thereon by looping an ordinary staple 8 over the juncture of my furring staple .and lathing, and driving the same to position; thus completing the reinforcement foundation for the reception of the first coat of plaster. The plaster may then be spread on the furring staples insuring a uniform even thickness of plaster, well anchored to the wall surface. The stresses throughout the plaster mass will equalize uniformly, and result in a compact homogenous and continuous exterior wall.

In extensive practice I have found that it is diificult to make speed, consistent with a good job, (and laying wire lathing is bid and consequently contract work) in the driving of the staple of my previously-mentioned issued patent into hard, wet or irregulargrained wood. I have rectified this serious deficiency and retardation by forming the first hump of the said staple with the upstanding and recurved head previously and specifically referred to; therefore, having described and illustrated the improvement of the body; a section ofiset from each.

shoulder so as to form a reinforced, outstanding driving head spaced from said body; and a prong extending from each head, the whole being in one plane.

3. A staple of the class described, com

prising a bearing section; a support section offset to one side from each end thereof and extending therefrom and parallel therewith; .a section ofiset at the end of each support section so as to form a reinforced, outstanding driving head spaced from said bearing section; and a prong extending, from each head substantially at a right angle to the bearing and support sections .and in the plane of said sections. 7

In testimony whereof I afiiX my signature.
