'IVIE'IHOID or TREATINGTWOOID. f I 7 Application filed September 5,1925. Serial No. 54,840.
My. invention consists in a method of compressing wood, the method being practised in such a way, that the'compressio'n pressure is exerted uniformly and simultaneously on a number of sides of the wood substantially perpendicular to the length of the fibre. In, practice, moldsflare used, which are so adjusted that the pressures occurring: in one direction release the pressure 10 effect in the still necessary other direction. In this way, the compression can-be carried to extreme limits, and if the pressure is eX- erted as. above stated, the lengths of the fibres .are causedto approach one another 1 without being bent or otherwise distorted.
By the method according to the present invention, it is possible to make molded wooden pieces of a predetermined shape, and having a predetermined density. The green or previously dried wood is cut into pieces.
The wood can even below grade, its measurements being determined according to the determined according to the kind of wood used, its moisture content, and the use for which the product is intended. As the heating is done, as long as the wood is under pressure, the heating can be carried much further than is ordinarily done, and the wood becomes visibly horny.
The pressed wood is especially suited as a material for the production of shuttles for the textile industry, showing a far greater hardness, tensile strength, etc., than molded pieces produced by previously known methods. It can be cut, turned or worked upon in any other way without any further'mechanical or other intermediate treatment.
The extent of the pressure and the degree and duration of the subsequent heating are In the drawing, in which I have illustrated, by way of example, my novel method, Figs. 1 and 2 show the open mold respectively in end and side elevation prior to compression, whereas Figs. 3 and 4 respectively show the closed mold after the compression.
According to the illustration, 4 the mold comprises members 1 .and 2, which are placed on opposite sides of the cut piece of wood 3 to be compressed. The inner walls of the mold members are bevelled toward the outside as indicated at 4 and 5, formingguide' surfaces for the lateral parts 6 and 7 of the mold. I i 2 The piece of wood is cut so that it corresponds to the cross-sectional shape of the mold, its compression being determined by the final position of the partsof the mold. After'the placing of the wood into the mold, the same is subjected to opposing perpendicular pressures on the parts 1 and 2. The parts 6 and 7 will then automatically cause a pressure effect perpendicular to the first mentioned pressure, whereby a homogeneously compressed piece of wood is attained. When after the completed compression, the
