MACH-HNE FOR woRKlNe RATTAN.

SPEQFICTION- forming part of Letters Patent No. 224,212, dated February 3, 1880.

' Application filed October 5, 1878. Patented in GermanyY September 21, 1877.

To all whom it may concern:

Be it known that I, ADOLPH MORITZ, of Schwerin, in the Empire of Germany, have invented certain new and useful Improvements The invention consists in a novel arrange-` ment and construction of cutting or reducing devices for subdividing the split portions of twig or' cane into pieces of any desired widths. Figure l is a front elevation of a machine constructed in accordance with my invention; Fig. 2, a plan ofthe same. Fig. 3 is a transverse section, in part, on the line afm; Fig. 4, a face View of a cutter-holder with attached cutters for radially splitting the twig or cane; Fig. 5, a transverse section, in part, ony the line y y; and Fig. 6, a front elevation of certain devices for peeling or barking the twigs before splitting or dividing them.

Referring in the first instance, or more particularly, to Figs. l, 2, 3, 4, and 5 of the draw-Y ings, A Aare the side frames of the machine, connected with each other by means of a crosstable, B, over which the material to be opererated on is introduced to the machine, either from the same side or from opposite sides of the machine, for the several operations to be performed lupon saidmaterial, accordingly as the machine maybe constructed in this respect to suit the convenience of lthe manufacturer, or as other circumstances may direct.

C -i's a main driving-shaft, which may be rotated by anyysuitable power. Upon this shaft is a spur-wheel, D, which serves, by means of gears EF, to rotate in their requisite directions 'upper and lower feed-roller shafts, Gr and H. The upper one, H, of these shafts is made adjustable and yielding relatively to the lower one by means of screws b and springs c.

ters., of which' there may be any number, being shown iithe drawings as carried by a single holder, K, supported by the table B on the delivery side of said rollers. A grooved guide, L, arranged on the opposite or feed side of said rollers, serves to direct the twig or cane to the grooved feed-rollersl and J. The upper roller,

J, is raised or lowered according to the diameter ofthe twig or cane to be split, and the cutter-holder K is correspondingly adjusted to centrally guide the willow or cane relatively to the splitting-tools e, and through circular apertures f in the holder K` and a back plate, g. VThe cutter-holder K may thus be adjusted up or down by means of vertically-adjustable supports h, attached to clips It, pivoted to stanchions l, and constructed to hook onto the upper roller-shaft, H, to retain the cutterholder and its cutters in position against the resistance of the cut, and to provide for the up or downadjustment of the cutters, together with the upper feed-roller shaft.

From the lower end of the cutter-holder lugs lt proj ectA downward through slots in the table, litt-ing sufficiently' loosely in said slots to permit the cutter-holder to follow the movement of the clips to which it is pivoted. The cutterholder, being pivoted nearer to the pivot of the clips than is the adjustable roller, will, of course, move a shorter distance than said roller,

so that the knives will preserve their proper' location with respect to both upper and lower rollers.

Fast also on the shafts Gr and H are other rollers, M N, for feeding the longitudi nally-split portions of the twig or cane, after delivery from the cutters e, to a shaping or planing and reducing knife, O, said split portions or lengths being introduced to the rollers M N through any desired number of guides m m, adjustable toward or from each other vby slides n n, and the lower one, N, of these rollers being grooved to receive the rounded portion of the twigs or cane. Said knit'eO, which acts upon the angular surfaces of the split portions of the twigs or cane, reduces said portions to the desired thickness.

To utilize these reduced split lengths or portions, it is desirable in many cases to subdivide them into strips of equal breadths. To this end said reduced split lengths or portions are introduced through an adjustable guide,y P, between supplementary rollers Q, and 1t on the shafts G and H. The lower one, Q, of these rollers has a plain peripherieal surface; but the upper one, It, consists of a number of disks, w, having knife-like edges or peripheries. Thesedisks are remo\fable,and arran ged at suitable distances apart by means ot' intervening washers. Aloosering,r,is also arranged upon said roller, and the screw 1", passing through the ange s, bears upon said ring and compresses the disks and washers between it and a tia-nge upon the opposite end of the roller, so that it will be seen thatthe number of the cutters and their distance apart may be varied. By passing the originally divided and reduced strips through these disk-cutters said strips are cut into lesser strips ot' a breadth corresponding to the distances of the cutting-disks apart.

When operating upon twigs, which it is necessary to peel or bark before splitting, shaping, or reducing and subdividing them, I attach to one ofthe side frames, A, ofthe machine, in place of the guideLand cutter-holder K, for operation in connection with the feedrollers I J, or without removing the guide L and cutter-holder K, for operation in connection with annnlarlygrooved special feedingrollers, peeling or barking devices or Scrapers T U, Fig. 6. These devices T U have reverse arched orv right-angle-shaped scraping-edges r s. One of these scrapers, T, is stationary and attached to the table B, in pla-ce, it ,may be, of the guide L, and the other, U, of said Scrapers is carried by a bracket, a', and is movable up or down by means of a lever, b', through a treadle or otherwise, an d a spring, c. The twig to be barked is first introduced sufliciently between the scrapers T U to allow the rollers I J, or other rollers corresponding thereto, to get a fair hold upon it, and so that said rollers will draw the twig between the Scrapers T U, the movable one, U, of said Scrapers being in the meantime pressed down by hand or foot, and so that the sharp edges r s will strip the bark from the twig passing between the scrapers. In some cases,instead of the scraper U, a roller covered with rubber may be used for operation in connection with the scraper T.

I do not claim the devices for radially splittingl the twigs or cane, for planing, shaving, or otherwise reducing the dat surfaces, or for scraping or peeling the twigs or cane, but merely describe them as useful adjuncts of my invention.

I claim- The combination of the adjustable guide P, the plai n roller Q, and the cutting-roller R, fitted with a series ot' adjustable cutting-disks, w, for subdividing into breadths the split rattan .or twig', substantially as specified.
