Description
A. J. GRA M LAMINATED WALLBOARD Aug. 17, 1937.
Filed Dec. 2, 1955 Patented Aug. 17, 1937 UNITED STATES PATENT OFFICE 2 Claims.
The object of the invention is to so construct laminated wallboard, particularly the kind that is made of fir wood, that it will present the effect of tiles or panels or random width planking,
thereby making installation possible in such a way as to conceal the joints or seams between adjacent boards and make unnecessary the use of battens to cover the seams, as is the conventional practice.
With this object in view, the invention consists in a construction and combination of parts of which preferred embodiments are illustrated in .the accompanying drawing, wherein:
Figure 1 is a perspective view of a section of laminated wallboard constructed in accordance with the invention.
Figure 2 is a view similar to Figure l but showing another form of the invention.
Figure 3 is a view similar to Figures 1 and 2 but showing still another form.
Figure 4 is a detail perspective view illustrating a modified form of joint or seam.
In carrying out the invention, if the boards are to be made to present the appearance of random width planking, the top lamina I0 is grooved at uniformly spaced intervals, as indicated at H, to present the appearance of a molding inset and this same form of grooving is carried out at the side edges, as indicated at l2, but so as to bring a half groove at the immediate side edge in order that when the next adjacent board or plank is placed the complementary grooved portion of that will add to the first, so that there will be an apparent molding spanning the joint or seam, the latter being at the bottom of the center groove of the molding, as indicated at IS in Figure 1.
The side edges of adjacent planks may be formed with cross sectionally Veshaped tongues and grooves, as indicated at H, to insure an interlock between adjacent boards and maintain their outer faces in a common plane.
Instead of interlocking side edges, as indicated at ii in Figure 1, the joint or seam may be made as indicated in Figure 4 in which the series of grooves are made at the side edges, as indicated at IS, with the bottom of the center groove at the seam. But in this form, the top lamina of the one board extends laterallybeyond the remaining laminae, while in the adjacent board, the top lamina is of a width less than tli'eremaining laminae by an amount equal to the lateral extent of the corresponding lamina of the companion board, as indicated at IS in Figure 4.
Instead of grooving the top lamina as described with respect to Figures 1 and 4, the latter may be made of a series of parallel'strips, as indicated at H in Figure 2, and in the spaces between these strips may be disposed molding strips l8. At the side edges, the strips I! are inset from the edges. of the bottom laminae half the distance of the spacing between companion strips l1, so that the molding strip, ,as indicated at l8a, may be made to span the joint or seam between adjacent boards.
As the invention iscarried out in that form shown in Figure 3, the top lamina I9 consists of flat panels simulatingv in size a tile and are arranged, as are tiles on a wall surface, with intervening molding strips 20, these strips covering the seams between adjacent planks both where the vertical and horizontal seams appear.
Where there is a horizontal seam in that form of the invention shown in Figure 1 it is concealed by a molding strip set half in the rabbet 2| of the one board and half in the corresponding rabbet of the adjoining board, or the horizontal seam may be made according to the construction set v out in Fig. 4.
The invention having been described, what is claimed as new and useful is: g
1. A laminated wallboard of which the top lamina is composed of a plurality of uniformly spaced planks or panels, and molding strips intervening between the planks or panels, the molding strips being secured to the next under lamina and having their top faces. in the same plane as the top faces of said planks or panels.
2. A laminated wallboard of which the top lamina is composed of a series of planks or panels uniformly spaced with those at the edges otthe board inset from said edges a distance equal to half the spacing between the planks or panels to provide rabbets at the edges, and molding strips intervening between the planks or panels and disposed in the rabbets of adjacent boards, the molding strips being secured to the next under lamina and having their top faces in the same plane as the top faces of said planks or panels.
