PATTERN FOR MOLDING ORNAMENTAL PLASTIC VENEER Filed May 19, 1949 m. H f" |G.5. '5

INVENTOR. FRANCIS J. GEDMINAS A TToe/vz Y Patented Sept. 11, 1951 PATTERN FOR MOLDING ORNAMENTAL PLASTIC VENEER Francis J. Gedminas, Philadelphia, Pa Application May 19, 1949, Serial No. 94,208- -'3 Claims. (01. 25118) My invention relates to a device for forming plastic veneer upon walls or surfaces for simulating stone, bricks, blocks, or the like.

An important object of the invention is to provide a device which will permit of the veneered surface having an ornamental or colored coating, without applying the same to the artificial mortar joints.

A further object of the invention is to provide a pattern, for producing the design in the veneer,

which pattern is of simplified construction and has a large range of adjustments for producing difierent shapes.

A further object of the invention is to provide a pattern which is flexible and may be applied to a flat or curved wall surface.

Other objects and advantages of the inventio will be apparent during the course of thefollowing description.

In'the drawings, forming a part of this appli-* cation, and in which like numerals are employed to designate like parts throughout the same,

Figure 1"is a fragmentary side elevation of a wall preparatory to applying the plastic veneer,

Figure 2 is a side elevation of the assembled pattern, parts broken away,

Figure 3 is a side elevation of the plastic Veneer after being applied to thewall, the assembled pattern being in place, parts broken away,

Figure 4 is a transverse section taken-on line 4-4 of Figure 3,

Figure 5 is an enlarged side elevation of one of the pattern strips,

Figure 6 is a transverse section taken on line 66 of Figure 2,

Figure 7 is a side elevation of the completed plastic veneer, with the pattern removed, parts broken away,

Figure 8 is a side elevation of the plastic veneer showing the pattern in place therein and adjustecl to form a brick or block design, parts broken away, and,

Figure 9 is a transverse section taken on line 9-9 of Figure 1.

In the drawing wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral Ill designates a vertical wall which is illustrated as formed of wood, although it may be formed of other suitable material. Secured to the outer face of this Wall by any suitable means, such as staples is a foraminous metal sheet H, which may be a wire mesh or expanded metal lath.

In accordance with my invention, I provide a pattern which includes a plurality of strips l2,

i3 and I4, which are identical except that'they and throughout its entirev length with holes l5 which extend through the outer face of the strip but terminate short of its inner face, and these holes are equidistantly spaced. .Ea'ch strip is tapered in cross-section and decreases in width inwardly, providing inclinedsides I6, and outer and inner faces I! and I8, which are parallel and vertically disposed in use. These strips are adjustably and detachably connected by staples [9 which are interchangeable and adapted for insertion within the holes l5, and are readily removable therefrom. The staples project outwardly beyond the outer faces I! so that they may be conveniently manipulated. The strips are preferably formed of-rubber reinforced with fabric and are somewhat flexible, which will permit them to be applied to a fiat wall or to a curved surface like a cylindrical pillar. Figure 2 shows the strips assembled and connected for producing a rough cutstone pattern.

In the practice of the method, a plastic veneer 20 is applied to the foraminous sheet ll secured to the vertical wall I0. The mix 'for"the plastic veneer is suitably stiff so that it will not slouch prior to setting. This plastic veneer may contain a mixture of sand, sodium chloride, lime and water, the volumes being optional except that the mix shall be suitably stifi, for the purpose stated. Any other suitable mix may be employed. The veneer 2B is applied by trowelling or the like. After the plastic veneer 20 is thus applied to the vertical wall, the individual pattern strips are pressed into the plastic'veneer 20, and arranged to produce the desired design. The design shown in Figures 2 and 3 simulate rough cut stone. The strips 12 may be generally horizontally-arranged while the'strips l3 and I4 may be diagonally arranged. After the strips are pressed into the veneer 20 so that their outer faces are substantially flush with the outer face of the veneer, the strips are connected by the staples I9, which are forced into selected holes l5. It is obvious that since the holes extend throughout the entire length of the strips and are equidistantly spaced, the strips may be arranged in varied relation to each other. By connecting the strips they produce a unitary pattern. The assembled and connected strips constituting the pattern may be held stationary in position, by any suitable means, such as wood strips S held in place by clamps. The unitary pattern thus held in place will oppose any slouching tendency of the veneer, before it sets. The outer face of ing mortar joints.

the veneer with the pattern strips embedded within the veneer may be suitably worked by the conventional trowel or by a vibrating trowel. If it is desired to provide the veneer 20 with an ornamental face, crushed stone, or crushed glass or the like, is applied to the outer face of the veneer, before it sets and while the pattern is in place, and this face worked into the veneer. The crushed :stcnefor the like may be appliedby trowel or an air blast containing the crushed stone therein. Instead of applying the solid particles to the outer face of the veneer, such outer face may be colored or tinted'by paint-cor like material. The advantage in applying the coating to the outer face of the veneer, while the pattern is still in place, is that the coating "of solid particles or paint is kept out of the egrooves formed by the pattern strips. The veneer is then allowed to set or harden, after which the pattern strips are individually disconnected from each other by: theremoval of'the' staples, and separated f-irom the lset veneer, providing grooves '22 having thetfdesi'gnzof the pattern andsimulat- The outer zface of the veneer "will then simulate irregular-cut stone having f mortar joints.

I mayrprovide a pattern for-producingia veneer havinga design simulating ilai'cl bricks orblocks,
