To all whom t may concern.'

Be it known that l, ORIN T. Cnown, residing at Hayward, in the county of Ala meda and State of California, have invented a new and useful Furring and Fastening Device, of which the following is a specification.

This invention relates to improvements in devices for the furring .of walls, andin particular to such a device in the form of a holding, supporting and binding staple adapted for use with wire lathing, the combination forming the anchoring or foundation means to receive and support a plaster cement coating for walls or the like. .K

The present common method of anchoring plaster to the exterior walls of bungalows and buildings, is by laying wire mesh f .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 fabricated wall surface flush rii with the wooden furringstrips and the latter bedded in the wet plasterl 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 line hair-like cracks throughout the. wall. These cracks tend to become longer and wider as the annual seasonal changes take place, and eventually patches of plaster drop off.

An important object of my invention is to overcome the above initial fine cracks, and thus extend the life of the wall to a very marked degree and present a uniform and continuous surface.

@ther important objects of the furring device are, that it shall carry its own fastening means for securement to a surface, and also that the same means shall secure the wire lathing to position on `the same surface, and thereby reduce the number of parts and instrumentalities producing such walls to a minimum; the provision of means by which building-paper may be applied and secured to a wall at any time independent of the presence of the wire lathing; the provision of such means by which the metal netting may be applied and spaced from and anchored to a wall at any time after the paper has been placed and fastened, or even no paper is used at all gv the provision of`such means that will effectively stretch and secure the metal netting, leaving a plane surface without any projections whatsoever to catch on or obstruct the plasterers darby and thus interfere with its efficient action in smoothing the wall or ceiling.

Other features than those enumerated will appear hereinafter.

In the accompanying sheet of drawings, I have illustrated the method and means of carrying my invention into effect, in its most approved form.

Figure l is a plan of a furring staple, in which my invention principally resides.

Figure 2 shows the same staple in side elevation, and shows also in section, the sheathing and the paper applied thereto, and the netting positioned upon the staple but not secured thereby, as the upper end of the staple is not yet driven home.

Figure 3 shows certain parts of Fig. 2 enlargedfor clarity, with the upper end of the staple driven home, thus stretching and binding the netting in place. Also the first and finishing coat. of plaster is shown applied and in section.

Figure l is a face View of a section of wall showing portions of the sheathing, building-paper, my staples, and netting secured thereby.

Referring to the drawings and figures thereon: `Upon the sheathing l is applied the building-paper 2. My anchoring staple in its entirety is denoted by 3. lt comprises the wedge-shaped point 1l, 'the driving and spacing shoulders 5, and the point 6 on the recurved endi. The point 4 has a wedge edge at right-angles to the plane of the body of the staple as shown, and for a purpose to be presently stated.

The paper 2 is held against the sheathing l by the shoulders 5, and the netting 8 is spaced from the wall by the straight portion 9, of the staple. The middle spacing shoulders 5 may be omitted in short staples but are desirable in long ones.

ln practice, the paper and netting which come from dierent sources, often reach the work at widely different times, hence it is of the greatest importance that it should be possible to apply and secure the paper in place when it arrives, and apply the netting any time later lwhich is sometimes days and weeks after the paper has arrived.

The importance of my invention resides in the fact, that the same instrumentality is usedfor securing both paper andneitingto the' Wall'` evenJ-Wh'enapplied-at different times; This results in a saving in cost,..ina te'rial,l labor and time kover the present. method of applying the many and different devices for tho-se purposes.I Y. v Y

ln using mystaple, IJthe paper 2 is applied beginning at the bottomuofthe-Welland Workingupivarch and is held to the Wall by f .driving the points i therethrough iand1 )intothe sheathing 'up .toi` the shouider 5.
