R. L.. KAYE BUILDING UNIT Dec. 10, 1940.
Filed March 31, 1939 INVENTOR. POBERT L5: Kay: BY swam/M ATTORNEY Patented Dec. 10, 1940 UNITED STATES BUILDING UNIT Robert Lee Kaye, Newark, N. 1., assignor to Briktex, Incorporated, Newark, N. J.
Application March 31, 1939, Serial No. 265,192
4'Claims. (01. 20-5) The invention relates to materials to be used in the construction of houses or other buildings as weatherproof fiber board siding to take the place of wooden siding and weatherboarding for 5 the outer wall covering for houses or buildings. The material also may be used as a veneering for walls of buildings where it is desired to simulate brick, tile or other selected finish of a highly diversified character.
It is accordingly the object of my invention to provide a material suitable for construction of walls made of fiber board, paper board, etc. which is formed with additional material and provided with a finish or outer layer or coating of material which makes it available as an outside wall construction material.
A further object of the invention is to provide a new process of manufacturing building covering units of the type hereafter to be described,
wherein by the steps taken the units are reinforced so that they will withstand hard abuse and be more rigid when applied than ordinary siding units.
other objects and advantages will be more 26 apparent from the following description wherein reference is to be had to the accompanying drawing, upon which Figure 1 is an elevational view showing the face of the unit.
so Figure 2 is a view of the edge of the unit shown in Figure 1.
Figure 3 is an elevational view of the back of the unit shown in Figure 1. Figure 4 is a view of the end of the unit shown 35 in Figure 1.
Some of the features of the invention include the reinforcing elements, the arrangement of the units to form a wall covering, their proportionate lengths in relation to the spacing between dis- 4) tance of the studding; the staggered relations of the vertical joints of a contiguous horizontal row, and generally, all details of the construction of the units.
The length of the units shown in Figures 1 and 4s 3 are ordinarily about 48 and the width is ordinarily about 15%". Each unit in this instance engages four studs, the distance between the studs being about 16". The long dimension of the slab is transverse to the studding and the 50 end overlapping or abutment of contiguous slabs of the horizontal rows, preferably takes place on the studding.
A fiber or other type board III is preferably, dried to remove all of the moisture or render the BI board substantially bone dry at about 400 F.
The hot dry board is then surface impregnated with hot waterproofing compound such as asphalt, tar, wax, and the like. After the surface of the board has been surface impregnated or coated as by spraying with hot asphalt or the 6 like, the excess impregnating or coating compound may be removed by mechanical means such as squeeze rolls or scrapers. It is not absolutely essential that the excess waterproofing compound be removed by mechanical means. The coated or impregnated board is dried or baked in a high temperature oven at about 350 to 450 F. When the baking operation is complete the board containing considerable heat and the impregnated or coated fibers are soft and pliable. While the unit is in this condition it is passed between one or more pair of calendering rolls. The calendering rolls burnish or smooth the surface waterproofing compound and fibers thus sealing the back surface and giving such surface a vapor proof finish. The finish is generally smooth and glossy and may be termed a vapor barrier.
The board while still hot is passed through what is termed an impress roll having thereon the design shown in Figure 3. There is formed on the back of the board imprint lines II which preferably are about V of an inch in depth. The action of the impress roll is to drive the waterproof- 3 ing compound deeper into the board along the lines II which forms a series of inverted beads. These beads give added strength and rigidity to the board, and furnish the applying mechanic with guide lines for cutting or dividing the unit on the job. The lines I! are preferably aligned with the mortar joints on the face of the units.
The board it now has applied a suitable mastic II to one surface. While the mastic is hot, granular material I2 is spread over the surface there- 0 of. The granules are now pressed into the mastic material. The unit is now passed to a suitable embossing roll where brick simulating elements or the like is formed. Between each element l3 and M are formed mortar simulating lines.
The board Ill may be shiplapped so that tight joints are provided with adjacent units. These units may be secured directly to the studding or may be used as a veneering for walls and the like. 50 In either instance the units are preferably secured in place by suitable fastening means such as nails. The fastening means pass through the unit and into the studding.
In the preferred size the units are 48 long 66 and 15%" wide, this gives a coveringisurface of 48" by 15" as shiplap is preferably employed.
What I claim is:
l. A building unit comprising a fiber board adapted to be secured to a building wall, weatherproofing material applied to the exposed surface of the board and designed to simulate a masonry construction with mortar bars therebetween, the opposite face coated with asphalt and impressed grooves in the asphalt coated board surface, said grooves substantially in line with mortar lines on the exposed surface.
2. A buildin opposite faces of the board surface impregnated with waterproofing compound, one face having applied thereto weatherproofing material, and designed to simulate masonry construction with mortar bars therebetween, impressed grooves in the opposite face of the board substantially in line with the mortar lines, said grooves having unit comprising a fiber board,
walls thereof surface impregnated with asphalt.
3. A building unit comprising a vegetable fiber board with one surface shaped to simulate at least two rows of bricks with mortar bars therebetween, the masonry simulating surface weatherproofed, the opposite surface impregnated with waterproofing material and saidopposite waterproofed surface having impressed grooves therein, said impressed grooves substantially in line with the mortar bars.
4. A building unit comprising a fiber board with one surface weatherproofed and the weatherprooflng designed to simulate rows of bricks with mortar bars therebetween, opposite face surface impregnated with waterproofing material, said waterproofed surface having impressed grooves substantially in line with mortar bars and said last mentioned surface having a smooth and glossy surface acting as a vapor barrier.
