FUR-RING ros'r.

Application filed June 2,

I with the lath for binding the latter against the spacing block in outstanding relation to the sub-siding; a further object is to water proof the spacing block whereby a water tight connection may be obtained between the spacing block and the building paper commonly disposed across the face of the sub-siding pr1or to the application of the lath.

With the foregoing and still further objects and purposes in view which will appear as the description proceeds, my invention resides in 5. the combination and arrangement of parts and in the details of construction hereinafter described and Claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope'of What is claimed, without departing from the spirit of the invention.

of the furring post approximately on line 66 of Fig. 3;

t Figure 7 is an enlarged median sectional view of the spacing block, with the pointed end of the nail projected part way thereinto;

Figure 8 is a view in cross section of the spacing block and nail; and

Figure 9 is a median sectional view of the spacing block divided into upper, lower and intermediate sections, with the nail removed.

Referring to the drawings in detail, throughout which like reference characters designate like parts;

The numerals 1, 2 and 3, designate, respectively, the sub-siding, building paper, and the wire lath or netting, of a stucco structure; the lath or netting 8 being secured to the sub-siding 1 in outstanding relation thereto, by means of r the present improved furring posts 4;

The sub-siding 1 comprises preferably the usual boards secured across the studding, joists etc., forming the frame of the walls and the like of stucco structures adapted to receive a coating of stucco composition.

Across the face of the sub-siding 1 is preferably secured a course of building paper 2.

The wire lath or netting 3, which may comprise anysuitable wire lath, in the persent instance consists of the inter-woven wire netting commonly known as poultry netting and embodies diamond-shaped hexagonal meshes formed of single Wires 5 twisted together at short intervals thereby forming inter-twisted portions 6'; two of said single wires converging into said inter-twisted portion form the letter Y, of which said inter-twisted portion forms the stem and the single wires the upper branched portion thereof.

The furringposts 4 comprise each a spacing block/Z, which is preferably cylindrical in cross section and has upper and lower flat sides disposed in parallelism, and a central perforation 8 extending from one to the I other of said flat sides, and a nail 9, the latter has one end pointed as at 10 and is provided at its opposite end with a flattened head 11.

The spacing blocks 7 are preferably formed of paper pulp or other suitable fibrous composition, provided with a water proofing material such as bitumen, pitch, paraffine,

resin, or a combination of two or more of said water proofing materials; the composition while in a plastic state pressed into sheets of suitable lateral dimensions and conformmg in thickness .to the thickness required for the spacing blocks, which are cut therefrom with suitable dies or cutters, the latter also forming. the perforations 8 as well as the' in dentations 12, 12 extending across the face of the blocks. If preferred,the said water proofing materials may be eliminated'from the fibrous mixture prior to pressing 1t lnto the sheets, and the spacing blocks instead treated for, water proofing by immersing them in fluid bitumen pitch, or resin, or paraffine, or a combination of any of them, which may be rendered fluid by means of heat and the blocks immersed therein while hot, or it may be liquefied by means-of solvents, .or by means of both heat and solvents.

In case the spacing blocks are water proofed after forming or cutting them out of the fibre sheets, it is unnecessary that the water proofing material penetrate to all parts "of the blocks, but it will be sufficient if the partsthereof adjacent the outer shell are water ,proofed and thereby prevent water from penetrating to the interior of the blocks. r, v v Informing the fibre sheets,the plastic mixture is compressed to provide a good and sufficiently: solid block towithstand any ordinary impact of the hammer when the nail is driven home for securing the lath thereagainst, without crushing, yet to be sufliciently yielding so that the lath wires may be readily pressed into the face thereof by the nail head when the nail is in the usual manner driven a proper distance in the wall.

- The nail 4 and spacing block 7 are intended to be assembled prior to the application of the device to the .wall, and in order to better retain the block ,frictionally on the forward end of the nail, the perforation 8 is made substantially, smaller than thejdiameter of the nail "(seeFig 7), whereby when the nail is forced into the perforation it will cause the fibre material adjacent said perforation to be bent downwards at an incline to the sides of the perforation. ;This inclination of the.

fibre material in engagement with the sides of the nail, causes it to bind firmly thereagainst particularly when f an attempt is 11'1t1C-l6 to withdraw the nail orback it-out of th'eblock, thus preventing the latter slipping off thenail accidently during transit of the device from factory to lath or when handling it during its application to the'wall,

, In Fig. 9 is shown a sectional view of one of the spacing blocks separated nto several parts or. sections. In pressmg together the plastic pulp or emulsion to form the 'fibre sheets, the fibre particlesbecome disposed 'ingeneral in layers in parallelism with the upper and lower sides of the sheets. The ends, ofthe fibre particles adjacent the perforation '8 are engaged by the nail.

when the latter is forced into the ,relatively small perforation, during the assembling iof the device, and bent downwards at an angle'or incline with the sides of the nail, thereby causing the perforation to become enlarged diametrically. asindicated bythe reference character 8. 1

To apply the present iinprovedfurring post to the wall for'attaching the wire" lath Vornetting thereagainst in outstanding relationthereto, the forward end of the device including the spacing block, is projected through one of the meshes of the lath or netting andmanipulatedto dispose the nail in the crotch formed by the intersection of two of the lath wires 5*with' theinter-twisted portion '6, with the spacing block 7 underlying said wires and inter-twisted portion, and with the indentations 12, 12 coinciding with said wires (see Figs. 1 and 2). The nail is then driven forward into the sub-siding 1 through the building paper 2, until the head] 11 engages and binds the lath wires firmly against the spacing blockin'said indentatlons and bids the block firmly against the building paper and sub-siding. In case of the elimination of the indentations 12, 12', the nail natives until the head 11 engages and presses the lath wires into the face "of the spacing, block.

- The disposition of the nail on the ,concaved secured in place for attaching the lath to the wall. The embedment'of the lath wires in the face of, the spacing blocks need not be 1 carried out to any pronounced extent, butit will be, sufficient when they are disposed into the outer surface of the blocks adjacent the bodyof the nail, to a depth equaltoone-half the diameter of the wires.

The furring posts may be disposed at such intervals along the wall as found best suited for the work "to be performed. I have found by practice that spacing them about eighti'nches apart each way an entirelysatisfactory job may be obtained.

7 After the wire lath or netting has been secured to the wall by the present furring posts, the stucco composition 13 is preferably applied by spreading it on the wall and on and around the lath until a stucco coating of'd'e'sired thickness is obtained;

I claim:

1. Inmeans of the character described, a spacing bloclr formed of composition material and having upper and lower substantially flat sides disposed in parallel planes, one of said sides having a- Y shaped indentation pres sed into the surface thereof, and a relatively hard nail having a head adapted to engage and hold lath material in said indentation.

2. Ail-article of manufacture comprising a resilient spacing block formed principally of fibrous composition material impregnated with resin material, said block being adapted for the driving of a nail therethrough so that the head of the nail will co-act with the block for binding lat-l1 material therebetween on either side of said nail.

8. An article of manufacture comprising a resilient spacing block formed principally of fibrous composition material impregnated with waterproofing material, said block being adapted for the driving of a nail therethrough so that the head of the nail will ooact with the block for binding lath material 20 therebetween on either side of said nail.
