applied thereto.
Where attempts have been made to use any one of the different forms ofexpanded metal or metal screening having relatively large meshes for supporting plaster, difficulty has been experienced in supporting the plaster or the like while in a semi-plastic state on the metal lathing or screening. In some constructionsa backing sheet has been placed behind metal lath or screening for supporting the semi-plastic material until it hardens. In such constructions it has heretoforebeen customary to provide spacing strips between the composition board and the framing timbers.
Thereafter the composition board is nailed to the spacing strips after which the metallic lath or screening is usually fastened'to the composition board. Each of these operations is costly and it is difficult to secure uniformity ofs'pa'cing and application of the different parts of the base to the framing timbers unless especially skilled workmen are employed.
I provide a plaster base in theform of readily transportable sheets comprising a backing sheet having corrugations formed therein whichserve'to space the sheet from the framing, timbers.
A metallic lath or screening is attached to the backing- For securing the metal lath or screening to the backing, securingmeans, one form of which is staples, are utilized whichare positioned to not only secure the metallic lath or screening to the backing, but also to preserve thecorrugations in the backing itself. Sheets so prepared can be transported to abuirlding site and applied directly to framing timbers with but a single fastening operation.
The accompanying drawings illustrate certain present preferred embodiments :of the in V vent-ion in which 19.;
-Figure 1 is a broken elevational view of a body of plaster and a plaster base applied to framing timbers;
Figure 2' is a'sectional view thereof taken substantially along the section line IIII of Figure l; and
Figures 3 to 8 inclusive are views illustrating several forms of fastening devices applied to backing sheets.
Referring to Figures 1 and 2, a plaster base comprises a backing sheet 2 having corrugations at formed therein, a fabric 5 for supporting a body 6 of plaster or the like, and secur-' ing means, here illustrated in the form of staplesor wires 7, to secure the fabric 5 to the backingsheet 2. The staples are preferably placed with their inturned ends 8 disposed at opposite sides of the corrugations 4 so that the staples not only secure the fabric in place, but also tions.
The sheet 2 serves to support plaster orv the like when in a semi-plastic state. After the plaster or the like is hardened and the fabric is thoroughly imbedded therein, it is supported by the fabric and the backin sheet has little work to perform. Accordingly,
commercial stiffening or reinforcing paper,
either chemically treated as by lcreosoting or the like, or plain, may be used for the backing sheet 2. The thickness of the paper is such that the corrugations 4 have considerable resistance to bending so that they serveto stiffen the plaster base and also to space the sheet 2 from framing timbers 9 a distance substantially equal to that of commercial laths." By so spacing the backing sheet 2,
the surface of the plaster is disposed at a dis tance from the timbers 9 which is the same distance as where plaster is applied to wooden lath, This construction eliminates the Ire-- cessity forspecially spacing the interior trim where my plaster base is used."
Thebase is secured "to the timbers by nails 10 drivenithroug h the base, preferably in the corrugations "4,With their outer ends clenched over the fabric 5. iStiifeni-ng rods Ell laid in the corrugations 4, "if desired.
While I havei'llustrated a fabric 5' in the form of screening, it is to be understood that different forms of metallic lath and expandmay be preserve the shape of the corruga-' ed metal may be substituted therefor without departing from the spirit of the invention or the scope of the appended claims.
By the term plaster as herein employed, I contemplate the use of any materials which are appliedi to a wall in a semi-plastic state and which harden into a solid condition.
Referring to Figure 3, a backing sheet 12 is provided with a rectangularly shaped depression 13 which serves as a spacing corrugation in-the finished base. Staples or Wires 15, one of which is illustrated, are driven into the sheet 12 on opposite sides of the depression 13 with their ends 16 clenched so that the staples 15 serve to preserve the shape of the corrugation 13 and prevent the side walls thereof spreading so that the effective depth of the corrugation is reduced.
. In'the modification shown in Figure 4, a backing sheet 17 is provided with a rectangular shaped depression 18, the shape of which is preserved by a staple or wire 19 which has its ends 20 clenched into the sheet on opposite sides of the de ression 18. The intermediate portion of t e staple 19 is bent toconform to the shape of the depression or corrugation. With this construction the upper surface of the corrugation is open, although thestaples 19 preserve its shape.
Referring to Figure 5, a sheet 21 is provided with a corrugation 22 in which a staple 23 is driven through one of the side walls of the corrugation and the ends 24 of the staple are clenched over the outer surface of the opposite side wall.
In another form of the invention shown in Figure 6, a backing sheet 25 is provided with a V-shaped corrugation 26, the shape of which is reinforced by a staple or wire 27 lying externally of the outer surface of the corrugation. The ends 28 of the staple extend through the sheet 25 and are clenched over the opposite surface of the sheet.
Referring to Figure 7, a sheet 29 is pro-v vided with a rectangularly shaped corrugation 30which is supported by an external staple or wire 31, the ends 32 of which extend through the sheet 29 and are clenched over the opposite surface.
' In Figure 8, I have illustrated a sheet 33.
having a V-shaped depression or corrugation 34 formed therein, the shape of which is preserved by a staple 5 of greater height than the staple 7 shown in Figure 2. The high staple 5 is used to span a stiffening rod 36 of considerable diameter when such is placed in the corrugation 34 and also to secure a fabric 37 in place. In addition the high staple permits a greater quantity of plaster to be inserted between the fabric and backing.
. It is to be understood that the securing device shown in Figures 3, 4 and 6. to 8, inclusive, maybe used to preserve the shape of a corrugation and may also be used to secure a fabric layer to the backing in a manner corresponding to that shown in Figures 1 and 2.
While I have shown and described certain present preferred embodiments of the invention, it is to be understood that it ma be otherwise embodied within the spirit 0 the invention and the scope of the appended claims.
