' 1 Claim. ((2. 20-35) This invention refers to veneered doors or composite sheets of material, which may be used for various purposes.

The particular object of my invention is to 6 provide a veneer door or analogous article having a frame and a filler or sheet therefor which is composed of' a plurality of channeled wood blocks adhesively secured, having smooth outer Walls adapted to receive-panels of veneer, which 10 veneer is cemented or otherwise secured to the composite element, resulting in a light strong door or other element, which is a simple, economical and durable composite structure that will not warp or otherwise develop imperfections.

. With the above and other objects in view the invention consists in certain peculiarities of construction and combination of parts, as will be hereinafter fully set forth with reference to the accompanying drawing and subsequently 2o claimed.

In the drawing: 4 Figure 1 represents a fragmentary elevation of a door, with parts broken away and in section to clearly illustrate my invention.

Figure 2 is a fragmentary, sectional end elevation, the section being indicated by the line 2-2 of Figure l.

Figure 3 is a similar sectional end elevation of a modified form of my invention.

Figure 4 is a perspective view of a block element, illustrating another form of my invention.

Referring by character to the drawing. A represents a skeleton frame of a door or other article, and fitted therein is a series of blocks I I i, which is shown assembled in break-joint relations, the entire mass of assemblage being glued together to constitute a solid sheet.

As best shown in Figure 2 of. the drawing, the blocks are longitudinally channeled or grooved to form center webs l and transverse webs 3, the same in cross-section simulating an H. The faces of the cross-webs are snugly abutted together and glued, whereby rectangular grooves will result to produce a hollow element having uninterrupted faces Y-Y, which faces are adapt! ed to receive veneer sheets 5 that are glued into place, whereby the surfaces of the door or other element will, in appearance, resemble a solid ele- 50 ment of any desired naturalwood grain finish.

Figure 3 illustrates another form of my invention wherein the blocks are longitudinally channeled on one side only, developing in cross-section a U-shaped member, which member, when 55 assembled as a filler, will provide the same hol- -ericy of the same to strain or pull the door .ele-

low channel structure as that previously described.

Obviously, while the grooves or channels in these exemplifications of my invention are rectangular in form when completed, the blocks may be channeled in V-shape, semi-circular, or in any desired out without departing from the generic principles.

the series of blocks. Otherwise, as shown in'15 Figures 2 and 3 of the drawing, the channels constitute dead air spaces, whereby the structure as a whole will effectively resist variations in' temperature, and owing to the outer walls of the blocks being smooth, and matched. uni- 20 formly, said walls present an unbroken surface upon which the veneer is glued, and will not show any irregularities, which would ordinarily result if this surface were interrupted.

Obviously, while I have shown the wooden '25 grooved or channeled blocks running longitudinally of the door, they may in some instances be positioned transversely or obliquely.

We call attention to the fact that the usual construction is to build up cores of a multitude of short blocks, which is an economy, as waste material can thenbe used. However, a long strip of block in building up the core is not desirable, for the reason that there would develop a greater tendency to warp. Routing or channeling the blocks, as shown, tends not only to lighten the core, but it also eliminates tendency to warp, due to fact that the channeling of the material weakens the blocks, and hence eliminates the tend- 4o ments' out of alinement. Briefly, the essential features of this invention are to lighten the door, which will materially save freight in shipping, and make it necessary to use fewer hinges in hanging the door; reduce the tendency of said door to warp from two angles; lessen the chances of the core block to cause warping, and, due to the transverse webs, lessens the chance for any warping of the veneer or door as a whole.

While I have particularly mentioned grooving or channeling the core blocks, obviously these core blocks may be bored, whereby they are lightened and hollowed.

While I have shown and described'several examplifications of my invention minutely as to details. it is understood that I may vary the structural features within the scope oi. the claim.

I claim:

As a new article of manufacture, a composite door comprising a plurality of solid, rectangular wooden blocks arranged in longitudinal alinement and matched together at their transverse edges end to end, said solid wooden blocks being 10 grooved longitudinally to form channels between each longitudinal line of blocks, the channels having a greater width and depth than the thickness of the material left in the blocks, the blocks in one line being staggeredly related relative to the blocks in an adjacent line, the longitudinal edges of the blocks being in abutting relation, whereby a. smooth unbroken face is had on each side of the blocks, and panels of veneerlng adhesively secured to said outer faces.
