SPECIFICATION forming part of Letters Patent N o. 676,680, dated .Tune 18, 1901.

Originalapplication filed August 29, 1899, Serial No. 728,906. Divided and this application filed December 1l, 1899. Serial No. 740.002. (No model.)

.To @ZZ whom, it may concern:

Be it known that I, JOSEF OsKAR KLIMscH,

a subject of the Emperor of Austria-Hungary,

residing at Vienna, in the Empire of Austria- I-Iungary, have invented certain new and useful Improvements in Apparatus for the Manufacture of Lon g-Stapled Vood-Pulp, of which the following is a specification, being a divisional part of the United States application bearing the Serial No. 728,906, led August 29, 1899. y

This invention relates to a machine for disintegrating and grindihg wood in the manufacture of long-stapled woodpulp suitable for the productionA of half-stuff cellulose and for other purposes; and the invention consists in a grinding and disintegrating apparatus comprisingagrinder provided at intera to be ground is fed into this machine with the fibers in the direction of rotation of the grinder, which is provided with disintegrating-knives c at one, two, or three points on its active surface. These knives c may be attached in any suitable manner-"as, for example, by means of bearings m, having ears n, that are adj ustably connected with plates d, screwed to plates e, Fig. l, such as are commonly used for mounting the grinder h. Fig. 2 is aside elevation of the same disintegrator. Fig. 3 is a section of a head or dat grinder. In this construction there are two disintegrating-knives c, the edges and points of which act on the wood in the direction of the ber on the blocks d, being pressed downward. Fig is a plan of the same construction. Instead of arranging the wood in the direct-ion of the fibers, as in Figs. 3 and 4, it can be arranged transversely with regard to the direction of motion of the flat grindingsurface. In this case, however, the length of the disintegrating-tools must be provided with edgesl andv corners or points. Cutters of this kind are shown in Figs. 9 and 10. Such duced by the inverse arrangement shown in Figs. l and 3. Fig. 6 is a section of a fixed grinder according to Fig. 5. Instead of the construction shown for feeding the wood in the various constructions of disintegrators the necessary pressure may be obtained by means of weights, hydraulic apparatus, friction, and so on. Figs. 7, 7, and 8 show a metal holder for the cutting-tools, which are either slid in or placed on and are secured by screws.

The operation takes place with water injection in the manner usual with the various disintegrators, and the only difference existing is that by using the disintegrating-knives the wood is disintegrated much quicker, producing a much better and larger fiber or pulp than has been possible with the com mon grinders Without knives.

It is unnecessary to describe all the details of the various constructions of disintegrators, much less the general plant, as only the grinding-surfaces, with the disintegrating-knives, which may differ from each other, form the subject-matter of the inventiomand therefore either all existing grinding apparatus may be provided with the new arrangement of cutters or other constructions of disintegrators may of course be designed on the principle of the double action, first, having regard to the disintegrating-tools, and secondly, to the simulioo taneous Agrinding action of the grinding-snrfaces as such.

t will be observed by reference to'Figs. 5, 7, 7, and 8 that the knives or cutters c are removably or exchangeably set in metal linings or bearings m and are firmly retained therein by a dovetail connection or engagement of the one part with the other, the said metal lining being let into the grinding-snrface. It is preferable to so construct and arrange the metal lining or bearing m that it may be moved upward for adjustment of the cutter when the same becomes worn. This may be accomplished in various Ways-as, for instance, by providing said lining m with ears n, Figs. l and 7a, that are adj ustably connected, by means of bolts o, with slotsp in the clainpingfplates d, which are screwed to the plates e, as before described. By loosen' ing the bolts o any required adjnstmentcan be readily imparted to the cutters.

What I claim, and desire to secure by Letters Patent of the United States, is-

1. An apparatus of the class specified comprising a grinding member having a grindingface at intervals,`each of said linings having its ends provided with ears n, the iixed clamping-plates d provided with slots p and the adjusting-bolts 0, substantially as described.

In testimony whereof I have hereunto set my hand 'in the presence of tWo Witnesses. f JOSEF OSKAR KLIMS'CH.
