T0 all whom 'it 'may concern: l

Bc it known that I, Jonas BnoLIN, a itizen of the United States, residing at Dul'uth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in DecorticatingMachinesg and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relatcsfto decorticating machines', and has for its object the provision of an improved machine. for removing shive and waste from flax fiber, and for other suitable purposes.

It consists of the constructions, combinations and arrangements of parts hereinafter described and claimed.

In the drawings, Figure 1 is a diagrammatic view of a portion 'of my invention, showing' the relation to each other of the materia-l parts which act directly upon the Hax to be operated upon, such parts comprising conveyers, combs, crushing rolls, and beat- Fig. 2 is a plan view of my said. invention, partly broken away. Fig. 3 is a side elevati-on of one form of my said inveninafter described Crusher rolls. Fig. 11, is an enlarged plan 'View of a portion of said invention, showing means for lifting the hereinafter described upper Crusher rolls to removal of obstructions. Fig. 5 is an en- Fig.- 6 is a rear end view of said invention.

In the drawlngs, 1 is a frame or support of any suitable construction, in which is spectively, which rolls support a conveyer -belt of any suitable construction, as 2, for conveying lax straw to respectively adjoining parts ofthe mechanism designed to operate upon it. Journaled upon said frame in front of said conveyer belt 2a, which may becalled the first, primary, or rear oonveyer belt, are a pair of horizontal primary toothed rolls 4C and 4; respectively adapted to turn oppositely to each other and draw in between them straw' fed to them lby the first conveyer belt, and, in a measure, to comb or disentangle the individual straws from, each other and from various foreign sube.; stances which may be mixed with them..l

Next in front of said rolls l1 and 4 is a primary single toothed roll 5, journaled upon said frame and adapted to`further comb said straw as it passes to the first air of the hereinafter described Crusher ro ls. Partly surrounding said roll 5 and spaced. therefrom is a diaphragm G, supported on said frame, and extending transversely thereof and adapted to hold the straw close to said roll 5 and to guido it? to the first pair of said Crusher rolls. Next in front of said roll 5 is a series of any suitable or desired number of pairs of prima-ry corrugated Crusher rolls, as 7, 8, 9, 10, 11, 12, 13 and 14; each pair comprising an upper and lower roll adapted to receive between them the straw which has passed the roll 5, the corrugations on each successive pair of said rolls preferably being finer or sha-llower than on the pair of rolls Next in front one or more pairs of primary smooth crusher rolls, as 15 and 16, each pair comprising an upper'and a lower roll adapted t-o receive between them the straw which has passed the said series of corrugated rolls. Beneath the said toothed and corrugated rolls and smooth rolls is a hopper, 17, preferably supported on said frame and adapted to receive such shive, or other material as may fall between, or from any of saidrolls, which hopper is provided with an exhaust port or conduit'18, wherein is located an Vexhaust pan 18a for removing the Acontents -of said hopper. Beneath the .hereinafter described screen 20 is a second hopperlSb provided with an exhaust port 18 wherein is positioned an exhaust Vfan 18d. Next in front of said smooth rolls isa transversely disposed forwardly and downwardly directed apron A, 'preferablytformed of angle iron7 and next in front of said apron is a rotary beater 19 of, any suitable construction, adapted to beat the straw as it passes oversaid apron from the smooth rolls. Below said beater is a screen 20 adapted to support the straw and guide -it in its forward course and to screen shive orwaste therefrom. Next forward of said beater, is a rotary primary dofl'er, or detlector 21 journaled on sai'd frame and positioned a little above the hori zontal axial plane of said beater, and ada-pt-V ed to deflect-saidstraw downward after it as passed said-beater. Next in front of beater,

end of a stock-adjusting or straightenin toothed belt, 23, which extends'upward an 'a rock shaft and extending aross the rearward face of said adjustinglbelthe office of which comb is to remove excess straw!" from said belt and throw it back into' the hopper Next'in front of'said stock-adjusting belt and preferably extending at its rearwardy end' beneaththe upper end of said belt, is a second-conve er ,belt` 25, of any suitable structure, whic ismountedon a pair of

rolls

26 and 26@ journaled in said frame. Said second conveyerfbelt'is adapted to receive the' straw and 'fiber as it falls from the stockedjusting belt. Next in fr'qnt of said second conveyer belt is a. second L-pair of toothed rolls comprising an upper and a lower roll 27 and 2'7, respectively, which rolls are adapted to draw between them the straw which is conveyed by saidfsecond eonveyerbelt and to further comb and straighten it. Nextin front of said second pair of toothed rolls, is a scc- ,ond toothed single roll 28 journaled upon said frame and' adapted to further comb said straw and fiber as it passes from saidsecond air of toothed rolls. VPartly surrounding said roll 2S, is a'second diaphragm 29, adapt-- ed to hold said straw close to said roll 28 and to guide it in its passage tothe first pair of the second series of Crusher rolls hereinr afteridescribed. Next in front of said vsecrespectively,

. roll-s and beneath said second isolated Y toothed roll and beneath said second seriesond toothed single roll lis a second series of any suitable or desired number-,of pairs of corrugated Crusher rolls, as 30, 3l, 32,33, 34,V

respectively (the number being reduced-in Fig. 3), each pair comprising an upper and a lower roll, and the corrugations on each pair4 of rolls being finer orshallower than on the pair of rollsnextin the rear in said series. Next in front of said second series of corrugated Crusher rolls are one or more. pairs of` smooth crusher rolls, as 35 and 36, each Vof which pairs consists of an upper and a lower roll adapted to receive between them the straw and ber which has passed said second series of corrugated rolls. Beneath said second'pair of toothed of corru ated and' smooth rolls is a 'third hopper 3 adapted to receive the-shive and other material which may fall into it from between said rolls, which hopper is provided with an exhaust conduit 38 within which is an exhaust fan 38 for removing the contents of the hopper. Beneath the hereinafter described screen 42 is a fourth hopper 39 pro- -i'nto which hopper extends the lower he straw andfi er are removed.

'inv rig. 5.

vided with' an.. exhaust conduit 39 within which is an exhaust fan 39h. Next in front of said second pair or series of pairs of smooth Crusher rolls-is a second transversely disposed forwardl and downwardly directed apron 40, prefere ly formed of angle iron, and next in front of said second apron is a rotary beater 41 adapted to beat said straw and fiber as it passes over said second apron. Below said'second beater is a second screen 42 adapted to support the straw and fiber as it passes in its forward course and to screen waste therefrom. Next forward of said second beater, is a rotary do'ifer, or deiector 42EL journaled on said frame and adapted to deflect said straw and fiber downward after it has passed thesecond beater, and passes' out of the forward end of the machine. v

The upper Crusher rolls are preferably all journaled eccentrically in rotatable journal bearings 43 which are journaled on said frame, so that when the journal bearings are partly rotated or scillated in one direction the rolls which are journaledin them will be raise'd and when said bearings are oscillated 'in the opposite direction said rolls will be lowered; thus ythe upper rolls maybe raised to facilitate Acleaning them or the 'I'.emoval of obstructions. Inorder either to oscillate said journal bearings, or to hold them stationary, I provide each` of them with an, arm, as 43a which may be intgral with the journal bearing as shownin Fig. 4, or which maybe clamped thereto as shown These arms are pivotally con"- nected at their upper ends 'to.connectin, ,1f` rpds, as 44. Mounted upon said frame above t e "upper crusher rolls andextending trans veiselyof said frame are slidable bars'45 to the ends of whichsaid 'connecting rods are coupled by links 46. Engaging said slidable bars and a portion of said frame are screws 47 for operating said sliding bars.

. Driving mechanism of any suitable. construction is provided for driving the several drive belt wheelV 49' keyed thereto fordrivj ing s ai shaft, gears 50 keyed to the axles of the upper crusher rolls, gears 51 keyed to the lower crusher rolls and adapted in op eration-to mesh with the gears on said upper rolls, gears 52 keyedl to the' upper toothed rolls, gears 53 keyed to thelower toothed rolls,v and 'meshing lwith the gears on the upi per toothed rolls, pinioiis 54 keyed to said toothed singlerolls, pinions 55 keyed to one of cach pair of conveyer belt rolls, pinions 56 keyed to the axles of the rotary beatrs, pinions 57 keyed tothe vaxles of each of said' doffers or rotary deiiectors, a pinion .58 keyed to the axle of one of the rolls 'supporting said adjusting belt, pinions 59' keyed to the axles of one of each pair of said crusher rolls and to the axles of one of each aus rolls of said machine, as a drive shaft 48, a

Til-5 adapted to transmit power from said gears 60 to said pinions, and adrive belt 63. l.

am aware that it is not new to use corra-- gated Crusher rolls, toothed comb rolls and eonveyer belts for euch purposes. I do not therefore claim such construction as broadlyl as might otherwisebe done. The value of my invention lies in the coinl'iination and arrangement oi.5 the parte which act directly onthe material to be operated upon, whereby a continuous operation to an elfectual re- Silit iS produced in one machine which heretofore has required transfer o'l the material from one machine to .another or to others, at the'expense of much time and labor. I also regard. the aprons A and 40 as particularly valuable and new features of said machine. It is obvious that said construction may be modified in many particulars within the scope of -my claim; especially may it be modified with respect to proportions, dimensions, arrangen'ient of the driving mechaniem, and by the sulistitution ot nlerlranical equivalente for certain oi ite parte, l do not therefore desire to be restricted to the exact proportions, dimensions, arrangements or forms described except as may be specifically required by said. claim.
