3 Claims. (Cl. 7Z-28) The present inventionrelates to stucco-walls having a simulated clapboard appearance, a method of making the same and to a fixture adapted for use in forming such Walls.

Efforts have 1neen made to produce al stucco wall having an outward appearance of clapboard construction by having the usual anchoring mesh for the stucco formed in stepped sections lhaving inclinations similar to that of a clapboard wall and applying the stucco over the mesh. The difficulty with such constructions, however, was that it was impossible to secure a smooth, even surface which would give the true appearance of a clapboard.

It is an object of the present invention ,toA provide la stucco construction having atrue, smooth appearance of a clapboard wall and the method of making thesame and in providing means ,whereby the surfaces yforming the simulated clapboard surface are insured to be smooth and accurate. This is accomplished, according to the present invention, by providing fixtureson thesupporting surface for the stucco which have trowel guiding surfaces thereon, one of which defines the lower edge of the board and the other of which defines the upper inner edge of the board. The guiding surfaces are so spaced from the support that the surface formed by troweling in the stucco between the fixtures and utilizing the guidingsurfaces on the fixtures to guide the trowel will produce a smooth, uniform surface having the upwardly inclined relation to the supporting surface as will produce the simulated appearance of overlapped clapboards.

While the two guiding surfaces may be formed separately, in the preferred form of the invention they are made as a part of a single xture, the lower guide surface forming the top of the clapboard below the fixture while the upper guide surface forms the bottom surface for the next upper clapboard, the lower guide surface being adapted inwardly from the upper guide surface to produce the necessary offset as is found in clapboard surfaces.

The fixture of the present invention can be formed of any suitable material by molding, extruding or stamping. it is herein illustrated as being made of sheet metal by suitable punching and forming dies. Each of the strips is provided with a plurality of holes through which mounting nails may be driven and also a plurality of holes through which the stucco may pass as it is troweled into engagement with the wire mesh secured over the sheathing.

In carrying out the novel method of the present invention in its herein illustrated form the supporting surface with the wire mesh thereon is prepared to receive and hold the stucco and the fixtures secured in position. The stucco is then applied and worked into the mesh. A trowel or other similar tool is then positioned with its upper end engaging the lower guiding surface of the one fixture and its lower end engaging the upper guiding surface of the xture below and the material troweledin smoothly in accordance with said surfaces. This re- Q States Patent 2 sults in a smooth, flat surface inclined tothesupport with theupper. end offset inwardly in the manner found in a normal overlapped clapboard surface.

A feature of the invention resides in the facility and accuracy with which the stucco can be applied and the simulated clapboard surface formed. i

Other features and advantages of the invention will eenpparent from the specification and claims when considered in connection with the drawings in which:

yFigure l shows a sectional view of a wall with the stucco in place. v f v Fig. 2 is a plan view partly broken away to show the various layers of construction.

Fig. 3 shows a plan view of one of the iixtures.

Fig. 4 shows asectional View of the fixture of Fig. 3 taken along line 4-4 of Fig. 3.-

Fig. 5 shows a sectional view of another form of fixture.

L Fig. 6 shows a sectional view of still another form of ixtnre.

While stucco walls of the present invention may be formed on masonry and the like structures, they are herein illustrated as applied over the sheathing 10 lcarried by the usual studs 1l and having over the sheathing, as usual, a building paper 12. A layer of wire mesh 13 is secured overthe building paper to form an anchoring means for receiving and supporting the stucco.

in order to produce a clapboard nish on the stucco wall, the present invention provides.r elongate fixtures 14 having trowel Aguiding surfaces, which fixtures extend horizontally alongand are secured to the sheathing to definefthe upper. and lower edges-of the ciapboard. f

. While thetrowel guiding surfacesmay be made as separate tixtures, inthe present preferred form ofthe invention-they are combined in a. single yfixture.k

Asshown in Figs. 3 and 4 .the .fixture Acomprises-upper andlower lmounting portions l5, 15 and aprojecting rib 17 `extendingoutwardly from theplane of thel mounting.. portions and having its edgey 18 forming the upper trowel guiding surface :for the-xture. As shown in Fig. l, the guiding'surface forms the ylower edge for Vtheclapboard above the fixture. .The fixture has a lowertrowel guiding surfacel'formed-lby a portion `Ztl-connectedsto the rib and spaced inwardly from the edge 18 to form the upper edge of the lower clap'ooard which is offset inwardly of the upper -clapboard as is usual in overlapped clapboard structures. in this form of the invention the rib is connected to the mounting portion 15 by a web 21 having a part 22 thereof lying in the plane of the guiding surface 1.9. The web 2i and a web 23 connecting the portion 2u to the mounting portion 16 are provided with large apertures 2d through which the stucco can pass during the application of the stucco and with which the stucco interlocks in the final structure.

In the form of the invention shown in Fig. 5, the rib is connected to the mounting portion 15 by an apertured web 2in which is inclined for the full width thereof while in the form of the invention shown in Fig. 6 the apertured web 2lb has its major portion iying in the plane of the mounting portion 15 and has a portion 22h overlying the back of portion 2t) and forming an upwardly facing groove at the inner end of the rib which can be used to enhance the interlock of the stucco with the fixture.

In accordance with the present invention means are provided in the mounting portions to facilitate securing the fixtures in place. As herein illustrated this comprises a plurality of holes 25 spaced along the strip to receive nails 26 which may be inserted in selected holes as may be required to etfect a rigid mounting thereof.

While separate corner pieces may be employed if desired, it is at present preferred to miter the strips at the corners to produce the desired guidance of the trowel during the formation of the simulated clapboard.

The fixtures can be formed of any suitable material by extruding, molding or stamping. In the illustrated form of the invention they are made as an elongate member from sheet metal by stamping and forming a sheet metal strip into the required shape. If the metal is not rust-resistant, it may be treated with rust-resistant material and if desired, may be colored or painted to conform with the color of the stucco.

In carrying out applicants novel method the supporting surface for receiving the stucco is prepared in the usual manner to receive and hold the stucco. Over this supporting surface the elongate fixtures 14 are mounted in a generally horizontal direction and nailed in place. The fixtures are spaced apart a distance equal to the desired exposed width of the clapboard since as is clear from Fig. 1 the bottom of the rib 17 forms the bottom of the upper clapboard while portion 20 forms the top of the lower clapboard. The stucco is then troweled onto the supporting surface and over the fixtures with the trowel guiding edges 18 and i9 of the fixtures serving to accurately position the trowel during smoothing of the stucco therebetween and provide a dat, smooth surface which produces the finished appearance of clapboard.

Variations and modifications may be made within the scope of the claims and portions of the improvements may be used without others.
