I 25d, 'Idtl.

Application filed March It, 1917. Serial No. 154,723.

To all whom it may concern:

Be it known that I, Anson M. STINE, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Furring-N ail, of which the following is a specification.

This invention relates to devices of the character designed; to'fastenmetal lath 1n place and-an object of the-invention is to provide a device which can be used in place of the usual wood furring strips and the ordinary nails. 1

In plastering buildings or other structures, for instance the exterior of houses which are to have plaster or stucco external finish, it is customary in general practice to fasten strips of wood, termed furring strips, to the boards forming the sheathing, said strips generally extending vertically. The metal lath, generally some form of expanded metal lath, is then nailed to the furring strips and finally the plaster or stucco work is put in place on the metal lath. In

buildings so constructed the plaster or stucco cracks at the furring strips, the cracking possibly being caused by the differen'ce in expansion and contraction of the wood and metal in the structure, and possibly also being due tothe fact that the plaster is not firmly bonded to'the metal lath at the places where the furring strips occur on account of it being impossible for the plaster to pass through the openings in the lath and hook over the backs of the lath adjacent the furring strips.

An object of this invention-is to make provision for allowing the plaster to flow through the openings in the lath over practically the entire area of the Wall so that the plaster will be of substantially uniform thickness throughout said wall, thus minimizing the cracking tendency.

Another object is to produce a furring nail of maximum simplicity for efifecting the foregoing objects.

The invention also relates to the method of making the improved nail.

Uther objects and advantages will appear in the subjoined detail-description.

The accompanying drawings, illustrate the invention:

being indicated in broken lines and dotted lines indicating the lath-holding member of the nail bent over into lath-holdin position.

Fig. 2 is an enlarged view 0 the nail shown in Fig. l.

Fig. 3 is a side view of the nail after it is partly made and before the abutments are bent therefrom.

Figs. 4, 5 and 6 are indicated by w", m Fig. 3.

There is provided a shank 1 adapted to penetrate the lath support or sheathing indicated at 2. The shank 1 is preferably provided with a point 3 so that it may readily be driven into the sheathing as shown in Fig. 1. The shank 1 projects from one end of an enlarged body portion 4 and from the other end of said body portion there pro jects a lath-holding member 5 preferably provided with a head 6 to facilitate driving of the nail.

Projecting from the same end .of the body 4- as the member 5 and substantially at right angles to the shank 1 is an abutment T, and proj cting from the same end of the body 4 as the shank 1 is an abutment 8 substantially at right angles to the member 5. Thus the abutments 7 and 8 project in opposite directions from the body 4 and are at right angles to the axis of the nail. Notches 9 are preferably provided between the adjacent ends of the shank 1 and abutment 8 and also between the adjacent ends of the member 5 and abutment 7 Thus when the nail is driven into the sheathing as shown in Fig. 1 the abutment 8 will rest snugly against the sheathing, the notch 9 adjacent the sheathing permitting this.

In the had shown in the drawings the shank 1, member 5, and abutments '2', 8 are shown of half round cross section and the body a is circular in cross section. The reason for this is that this nail may be formed, as shown in Fig. 3 of a rod or wire of circular cross section. The method of making this nail from a rod or wire of circular cross section is to split, saw or otherwise bifurcate the end portions of the rod as shown in Fi 3, the split or slot being indicated at It), and to then bend one furcation at each end of the rod outward from the adjacent .furcation and at rightangles thereto to form the abut ments 7, 8. Then the abutments 7, 8 will be cut ed to make them of the desired lengths.

practice a member of units as Idti Iltl

above constructed are driven into the sheathing as shown in Fig. 1 with the abutmcnts 8 engaging the outer face of the sheathing. The metal lath, indicated at 11, will then be placed in position, the members 5 readily passing through some of the perforations 12 of said lath. The lath will then be forced tightly against the abutments 7 and the members 5 will be bent inward against the lath as indicated in broken lines at a, Fig. 1.

Finally the plaster or stucco b will be applied to the outer face of the lath as indi cated in broken lines in Fig. 1.

It is readily seen that the abutments 7 and 8 serve to space the lath 11 from the sheathing 2, the space being indicated at c. When the plaster or stucco is applied to the lath it flows through the openings 12 of the lath and hooks over the back of said lath and it is noted that this hooking over of the plaster can occur over a maximum area of the lath because none of the openings in the lath are obstructed by the wooden furring strips, commonly employed in practice heretofore.

I claim:

1. A furring nail having a shank adapted to be driven into sheathing, having an abutment to engage the outer face of said sheathing, having a second abutment spaced from the first named abutment to engage the inner face of metal lath, and having a headed member adapted to pass through the lath and to be bent inward toward the lath to hold said lath against the second abutment.

2. A furring nail having a shank adapted to be driven into sheathing, having means projecting from opposite sides of the shank to space metal lath from the sheathing, and having a headed member adapted to project through the metal lath and to be bent inward toward said lath to hold the lath against movement away from the sheathing.

3. A furring nail having a shank, abutments projecting laterally from the shank at different locations lengthwise of said shank, and a headed member adapted to be bent toward the shank substantially as and for the purpose described.
