COMPOUND WOODEN PLATE.
Specification of Letters Patent.
Patented Jan. 30', 1912.
I Application filed August 10, 1911. Serial No. 648,327.
To all whom it may concern:
Be it known that I, HEINRICH HERMANN BASSE, a citizen of Germany, residing at Holtensen, Germany, have invented a nev;
which the following is a specification.
This invention relates to an im roved compound wooden plate or tablet 0 novel construction bled and possesses superior strength and binding qualities. 1
In the drawing: Figure 1 is an end view of a wooden plate embodying my invention, with parts of the upper and lower layers removed; Fig. 2 a plan thereof, and Fig. 3 a diagram showing the device for pressing the plates.
The core of the plate is composed of a plurality of wooden strips (1 which are spaced from each other as at b. Each strip a is provided on one side with a number of obliueqly extending grooves 13 and on the other side with similar grooves c arran ed crosswise to grooves 0. Each strip is urther provided with a longitudinal grooved extending in the direction of the grain o the wood. To the upper and lower sides of strips a are lued wooden covering plates 9, the grain 0 which extends at right angles to that of strips 0. To plates 9 are glued the hard wood surface veneers f. l
The elements being assembled as described are subjected to pressure by the device illustrated in Fig. 3. This device consists of a level cement floor 1-, and an overhead rail 2 upon which travels a crane 3 from which a massivescastmetal plate 4 weighing about which may be readily assemtwo tons is adapted tobe lowered. The
glued plates -5 are placed upon floor 1 and one or more of the weights 4 are by the crane lowered upon the wooden plates. The weights are allowed to remain in position for a length of time sufiicient for permitting the glue to bind, when the" operation is completed. t
By the use of the weights 4 in lieu of the hydraulic presses heretofore generally employed, several advantages are obtained.
The excessive available pressure of the hydraulic press would cause the glue to spread unevenly owing to the harder or softer, closer or w'der, of the wood fibers, so that small bubbles were apt to form during) the pressing operation. Furthermore y the hydraulic press an uneven heating and alsoan excessive heating was wasapt to destroy the the lue. So also the alternate heating chilllng of the press was apt to injurlously affect the wood, especially as running expenses made it practica eratlons.
I claim:
A compound wooden plate comprising a plurality of spaced cross strips having upper and lower intersecting oblique grooves and,
