LATI-I OR PLASTER BASE.
Application filed January 28, 1924, Serial No. 689,090. Renewed February 8, 1926.
This invention relates to improvements in lath or sheathing constructions adapted to support plaster or other cementitious material.
The primary object of this invention is the provision of' arelatively simple and inexpensive type of lath construction which is very durable, and which may be so used in building constructions as to directly support the plastering coat thereon withoutxthe necessity of providing the conventional. mortar coatings. *a
A further object of this invention is the provision'of alath or sheathing construction which may be used for economically construct-ing walls and ceilings, as the same is of'such nature as to effectively receive a plastering coat directly thereon, without the :necessity of providing the v'conventional scratching or browning coats, and in this respect not only being economical, from a material saving standpoint, but doing away with the necessity of operations now necessary and used with ordinary lathing.
The metal ylathing now in use for supporting mortarand plaster walls is `subject to oxidation incident to `intimate contactof the wet cementitious mass directly thereon, and this type of lathing is subject to eX- treme expansions and contraction incident to temperature variations. As a result it is necessary to place heavy coatings of mortar on metal lat-hing priorto the placing of the finishing coat or plastering. There is also in use a type of lathing formed of paper material which is of itself not sucient to support walls of any considerable weight, incident to the fact that absorption of moisture by the .paper lathing `will permit the same to buckle and incident to weight of the cementitious material the paper lathing is very often ruptured. With the improved lathing `a rigid lath base is provided which has securedl thereover any absorbentor fibrous body somewhat yieldable and to which plaster readily adheres, so that the plaster is` not directly sub-ject `to the rapid 'expansions or contractions incident to temperature variations kwhich might affect a lrigid base.
Other objects and advantages of this invention will be apparent during'the course of the following detailedv description.
In the accompanying drawing, forming a part of this specification, and wherein similar reference characters designate corresponding parts throughout the several views,
Figure 1 is a fragmentary front elevation Fig. 4 isv a cross sectional view taken M through the'. improved .lathing construction' showing the manner in which a plaster coating may be keyed thereto.
In the drawing, wherein for the purpose ofl illustration is shown only the preferred embodiment of this Vinvention the letter A Y may generally designate the lathing, which consists' of a supporting sheet B of rigid material, and a `less rigid and somewhat yieldable and absorbent sheet of plaster supporting material C xedly secured over the entire area of the backingmaterial B.
The base B of the lathing or sheathing A is preferably of sheet metal, rigid throughout. The material C is preferably some absorbent, yieldable, or fibrous material such as cardboard, felt,'asbestos, gravel surfaced paper or the like. The sheets B and C are of the same dimensions, a convenient size of lathing or sheathing being four feet by two feet. The facing surfaces ofthe sheets B and C are placed in' abutment through the length and width ofthe sheets, and they are fixedly` secured together in any approved manner, although preferably by punching apertures through the sheets E and C from the rear side of the supporting sheet B, thus providing tubular projections 15 which eX- tend into the material of the sheet C in a crimped relation therein, iixedly holding the sheets B and C in a stable and a nondetachable relation. v Thus openings 16 are formed VVthrough the lathing A. rlhe punchflexible sheet C will provide annular projections 18 about the openings 16, on the plaster` receiving face of the sheet C. rhis provides a roughenedA surface for the plaster receiving face oflthesheet C, and more readily enables the plaster or other cementitious materialr to adhere thereto..
In lieu of sheet metal for the rigid back sheet B, boards'may be used, although the most economical and the most efficient com- 4 bination for average use will be that of prod0() ing of these openings'into the absorbent or viding a thin sheet metal supporting ,back B With a card-board plaster receiving sheet C atlixed thereto in the manner above described.
The sheets of lathing or sheathing A are, ot course, attached by suitable nails or securing elements 20 to the studding E to 'pro` vide a Wall, andafter the sheathing or lathing has been so applied it is merely necessary to place the yplastering or'other cementitious coat on the exposed surface ot the sheathing. The plaster will, incident to the trovveling operation, iind its way into the openings 16, and small projections may form rearwardly ot the sheet B about the openings, to effectively key the plaster coat to thelathing or sheathing, as can readily be understood.
it will, ot couse, be apparent that the sheet B `t'mnishes the necessary rigidity'and supporting medium for the plastering of the Wall, and the plaster or cementitiousmaterial-is separated trennt-he metal sheet B by means of the absorbent, -yieldable, and fibrous material C which furnishes the necessary condensing and suction medium -tor Vthe lplaster coating.
Vilith the above described improved type ot lathing it is not necessary to provide the fiber mixed mortar coatings, and-a relatively light Weight Wall may be provided in a minimum time and With'less expense than is'noW customary. The pla-ster coating will adhere to the sheathing and cannot be `jarre'd loose therefrom incident to ordinary vibrations, because of the fact that there is a buiiing sur- :tace provided in the yieldable sheet C. The improved type of lathing is especially useful under extreme conditions ot' usage, and will readily absorb moisture, withstand vibration, frost, expand and contract incident to temperature variation, and will standiexf traordinary surface abuses.
It is, ot course, realized that numerous Ways may be used for keying or securing the plaster coating in adhering relation to the lathing, and it has even been contemplated to provide projections of a stub/nature tor securing the sheets B and C together and the plaster thereto.
Various changes in the shape, size, and arrangement ot vparts may be made to the 'form ot invention herein lshown and described,
.Without departing from the spirit ofthis invention or the scope of the claims.
