GQMPQUND To au whom it may concern Be it known that I, HERMANN BUirrnN,v a citizen of Germany, residing at Dsseldorf,A Germany, have invented new and useful Im-` provements in Compound Wooden'Plates, of which the following is a specification- This invention relates to an improved compoundwooden plate which is composed of an upper veneer, a lower veneer, and an intervening open-Work skeleton, which effectively prevents warping of the plate.

In the accompanying drawings, Figure 1 isv a top view\of my improved compound wooden plate; Fig. 2, a cross-section on line 2 2, Fig. 1A; and Fig. 3, a section at right angles to Fig. 2online33, Fig. 1. A

The letter a re resents an ucpper veneer. or plate, and b is a ower veneer or plate. Between' the veneers a b are arranged three layers of intervenin laths `or strips c d e, that form a skeleton. he laths'of each layer are parallel to each other and are varranged at, right angles to the laths of the ad]oining layer or layers. Thus the laths c of the lowermost llayer run at right angles to the laths d ofthe central layer, which 1n turn are arranged at right an les to the laths e of the uppermost layer. T e laths of each layer do .p not contact with each other, but are'spaced toforminterveningparallelo enings (marked c', d', and e', respectively.) I'l Specification of Letters Patent. Application led April 9, 1904. Serial No. 202,283.

l shoul he grain of adwooDl-:N PLATE.

atented June 19, 1906.

layers forming the compound plate cross each other. Thus the grain of veneer b runs parallel to the grain of laths d and veneer a, but at right angles to the grain of laths c and e. Allthe parts of the late are glued together or otherwise connecte into one integral structure. l

It will be seen that by my invention there is formed between the veneers a perfect lattice truss system, which produces the. best joinin attainable stability in all directions with a lminimum quantity of materiall If desired,

the structure may be curved instead of being `strai ht. L

atlclaimis-A A compound Wooden plate composed of an upperveneer and a lower veneer havingtheir ain running in the same direction,.a central ayer ofspaced parallel laths having then' am runningm a like direction ,and upper and owerllayers of spaced parallel laths intermediate fthe veneers and the central layer and having their grain run at right angles to that of the veneers and the central layer, substan tially as s ecified.
