EM'rUTrm-m, a citizen.- of the 'United States, rcsidi at Hastings, in thecounty of Barry'l an State of Michigan, have invented new and useful Improvements in Metal-Reinforced Veneer Panels, of which the following is a specification, reference bei had to t indrawings, formlng a part thereo l he purpose of this inventionis to pro-`- vide an im roved construction of 'panels made of a p urality of layers of veneer and ially for use in cabinet construction, eithenfas panels, shelves or partitions, Vwhich, notwithstanding the thinness and certainl resultant characteristics of the multiple-ply veneer structure, shall have adequatestiness in all directions, and otherwlsemeet the requirements of the use indicated. Y

It`consists in the elements and 'features of construction shown and described as ind`- cated in the claims,

In the di'awingsz-Fi re 1 is a perspecv-t-ive view of a panel em odying this invention. Fig. 2 is a plan view of a panel showing the oppositeside AI'rom that shown in Fig. 1, and having a portion of the layers of veneer broken away in part. Fig. 3 is a section at the line 3-3 on Fig. 1. Fig. 4 is a'perspective view of a piece the metal reinforce.-

The panel shown in the 4drawing corn- .prises exterior veneer layers, 1 and 2, whcse as gr ain extends' in the same 'direc-tion, beingr preferably that of the narrower dimension of the panel, which comprises a tlm-d1. intermediate lamina of wood having thegrain transverse to thdt of the exterior veneers, 1

and 2, the grain of said intermediate lamina being therefore longitudinal of the panel, as shown. v

A panel constructed of three layers with the grain arranged as described, which is the common construction for thin panels designed for insets, partitie s or lightshelving, is adequately stiff in th dlrection of the length of the grain of the surface veneers, because, first, of the stiffness of the wood in the direction ofthe' length of the grain, and second .md chiefly, because these two layers being spaced apart by the full amount of the thickness of the intermediate-layer which is thicker than either of them,-that is, by' the maximum distance possible with a given thickness of panel,' -.foperate as the tension e accompanylamina, 3.,

members oa truss structure; but in the transverse direction,that is, that of `the grain of the intermediate laminar-the advantage. of thenatural stiffness of the surface veneers in the direction of the length of' the grain being lost, and the middle layer on the contrary, is'quite easily bent or sprung m that direction, and indeed,can'fbe quite easily cbroken by bending'in. that direction.

To compensate for this deficiency, and at the same time preserve the finished a peare ance of the panel upon one surface, provide,1 metallic stiteners, 4, each of which'is a strip of sheet `'metal lfolded into channel forni, 'preferably having one of the flanges, f

die, iider than the other and furnished with a mixltiplicity of short lugs, 4", at it-s edge whi'h are folded, transversely to the flange,-that is, cross-wise to the channel. The-narrower Harige, 4, is let into asaw kerf, 5, cut in the longitudinal edge of the lpanel deep enough to receive said flange and of suitable width. to receive it tightly, so

that, in fact, the flange has to be driven into the kerf. By reason of the flange, 4, being narrower than the flange, 4, which has the lugs, said flange, 4", can be thus driven into the saw hert', notwithstandinf the projection of the lugs cross-wise o the channel,

and after it has been. thus driven into the i full depth so that the lportion lof the thickness of the panel at one side of tliesuw kerf is fullyv entered into the channel to the bottom of the latter, the lugs, 4, are forced into the surface of the vpanel, cutting their way through the outer veneer, 1, at that side and embedding themselves in the intermediate By this means, -the channel binder or reinforce, 4, is rigidly 'and permanently secured on the edge of the panel. Both longitudinal edges of the panel are furnished with such reinforce members. 4

It 'will be observed that by this construction,l the panel is left with one surface prei senting only the finished `Wood veneer to view, and suchpanels are by this means adapted for use in any cabinet structure in which only one-surface of the panel is exsential; but by elnployingsuitable metal, 'the appearance 1s not materially marred by the blnding for many purposes.

Preferably, in making the saw' kerf, 5, I avoidcutting between the outer veneer and the intermediate lamina, and prefer to make the kerf in the intermediate lamina, just inward of the unction'plane of the interior lamina and the veneer. By this means, the edge of the veneer is allowed to retain the reinforcement of a thin layer of .longitudinal grain of the intermediate lamina. and is prevented from splitting at the edge.

I claim:-

1. A veneer panel comprising exterior' 'layers of wood veneer having the grain in the same direction, and anl intermediate -layer of wood having the grain transverse to that of the surface veneers, in combination with metal reinforces for the edgestransverse to. thegrain of the surface, veneers, .such reinforces consisting of sheet-metal channels having one flange inserted in the edge to be reinforced proximate to one of the surfacelfveneers, and the other flange clenched upon'the op osite veneer surface i 2. A" veneer pane comprising exterior layers of ood`venecr having the grain in the same direction, and an intermediate layer of wood having the grain transverse to that of the surface veneers, in combination with nietal reinforces for the edges transverse to the grain ot' the surface veneers, such reinforces consisting of sheetmetal channels having one -flange inserted inthe edge to be reinforced proximate to one of the surface veneers, and the othe'i` flange clenched upon the opposite veneer surface, said last-mentioned flange being provided with a multiplicityr of lngspenetrating the vencer at that side.

3. wood veneer panel comprisingr a. plurality of thin 'layers of wood having their grains crossing one another, in combination with metallic binding,r for the edges, consisting ci" metal channelsA having one flange inserted into the edgeto be bound and the other flange clenched upon 'one surface of the panel.

In testimony whereof, I have hereunto set my hand, at Chicago, Illinois, this 11th day ofA May, '19I2.

EMIL TYDEN.
