WILBUR 1V1. STONE, OF NEW YORK, N. Y., ASSIGNOR TO OXFORD LINEN MILLS, A CORPORATION OF MAINE.

MACHINE FOR TREATING FIBROUS PLANTS.

To all whom it may concern:

Be it known that I, VILBUR M. STONE, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Machines for Treating Fibrous Plants, of which the following is a specification.

This invention relates to machines for treating fibrous plants, such as flax, hemp, and similar growths, for separating the fiber from the straw thereof.

The object of my improvements is to furnish a machine into which fiber bearing stalks or tow may be delivered and which without further hand manipulation and in one continuous operation will extract the straw and shive portions from the fiber and deliver said fiber in a substantially cleaned condition.

With this object in view my improved machine comprises mechanism illustrated in the accompanying drawings wherein Figure l is a side elevation with certain parts broken away to more clearly show its construction and operation. Fig. 2 is a plan view of the same. Fig. 3 is an enlarged detail side elevation showing more clearly brush 330 or 560.

My invention comprises broadly one or more cylinders each having grooves in the periphery parallel with the axis thereof and having a series of smaller cylinders or rolls correspondingly corrugated for coaction with the main cylinder. Said rolls are mounted for oscillation about the axis of the cylinder and are actuated to roll back and forth on the periphery of the cylinder dur ing the forward revolution of the cylinder. Preferably I arrange said cylinders with their coacting rolls in pairs, one such pair being shown in the present drawings. Also I preferably mount the series of rolls of one cylinder opposite to that of the other cylinder relative to the common plane of the axes of said cylinders.

Passing now to a more specific description, I provide the usual feed apron 2, one or more pairs of primary corrugated crushing rolls 3, 4, 5, 6, 7, 8, preferably having their corrugations decreasing in size from pair to pair. The first cylinder 9 is fixed to shaft 10 which shaft is mounted for rotation in suitable boxes in side frames 11, 12. Adjacent to and at opposite ends of cylinder Specification of Letters Patent.

Serial No. 500,965.

9 are oscillating frames 13, 14 freely mounted on shaft 10. Said frames are .connected to each other by webs or plates 15, 16 so that said frames will move in unison. Between oscillating frame 14 and side frame 12 gear 17 is fixed to shaft 10. In suitable bearings formed in oscillating frames 13, 14 are mounted for revolution and for coaction with the grooved periphery of cylinder 9 a plurality of grooved rolls 18, 19, 20, 21, 22, Said rolls are each provided with a gear, as 24 to roll 18, for engagement With large gear 17 on cylinder shaft 10. Also mounted for rotation in oscillating frames 13, 14 is brush or scraper roll 25 for coaction with cylinder 9. On the rearwardoutboard end of shaft 250 of brush 25 is fixed pulley 26 and which is driven by belt 27 from pulley 28 on shaft 10. A pair of corrugated transfer rolls 29, 30 is provided to carry the material being treated, from cylinder 9 to cylinder 90. Brush 330 driven by any convenient means, not shown, may be provided to assist the material into the bite of rolls 29, 30. Said cylinder 90, in all respects similar to cylinder 9, is fixed on shaft 31 mounted for revolution in suitable bearings in side frames 11, 12. Said cylinder 90 has mounted thereover in oscillating frames 34, 35 a plurality of grooved rolls as 32, 33 for coaction therewith, similar in construction and mounting to grooved rollslS, 19 and so forth below cylinder 9. Said cylinder 90 is also provided with a brush roll 36 having pulley 37 on the outwardly extending shaft 38 thereof. Said pulley is-driven by belt 39 from pulley 40 on cylinder shaft 31, all similar to brush roll 25 and the driving means therefor already described in con nection with cylinder 9. For leading the material being operated upon away from cylinder 90 corrugated feed rolls 56, 57 are provided. Also brush 560 driven by any convenient means, not-shown, may be provided to assist the material into the bite of rolls 56, 57. Said rolls in their turn deliver to apron 58.

One or more of the small rolls coacting with cylinders 9 and 90 may be provided if desired with means for endwise movement. One form of such means is illustrated in connection with roll 33 of cylinder 90. Said means comprises a pair of complementary cams 41, 42 fixed to oscillating frames 34, 35 respectively and concentric with shaft 43 of roll 33. Pivotally mounted within said roll for coaction with said cams are rolls li, 45 respectively.

Oscillating roll-carrying- frames 13, 14 and 34, 35 are actuated as follows: Outwardly extending from oscillating frame 8% is sleeve 46 and to the outboard end thereof outside frame 11 is fixed arm i7. Said arm 4LT has pivoted to its free end cam roll arm 48. Said arm has cam roll 49 pivotally mounted thereon for engagement with cam 50 011 shaft 51 mounted for rotation in side frames 11, 12. Arm 4-8 is bifurcated at its lower end for engagement with shaft 51. Oscillating frame 18 is connected to os'cil lating frame 34: by means of link Said link is pivoted at 53 to frame 34: and at 5i to upwardly extending arm 55 of frame 13. Cam 50 has apath of such contour as to impart to oscillating frames 34, 35 and 13,

14: relatively long oscillations each comprising several relatively short oscillations, whereby rolls such as 82, 33, 19, 20 and brushes 36, are caused to work back and forth in coaction with their respective cylinders.

The operation of my improved machine is as follows: Stalks of flax or other fiber bearing plant being spread on feed apron 2 and with their lengths in line with the direction of travel of said apron, said stalks pass into successive engagement with primary crushing rolls 3, f, 5, 6, 7 and 8. The straw of said stalks is thereby broken up into coarse bits or shives and more or less thereof falls down between said rolls. The partly deshived stalks then emerge from said primary crushing rolls and are fed against the corrugated face of cylinder 9 by which they are bent downwardly into the bite of roll 18 and said cylinder. The stalks then continue to pass downwardly and then upwardly around said cylinder over the succeeding rolls 19, 20, brush 25 and rolls 21, 22 and so forth. Said rolls 18, 19 and so forth by means of the instrumentalities described are caused to roll back and forth on cylinder 9 thereby providing a plurality of coactions of said rolls, brush and cylinder with the material therebetween,

to the further breaking of said stalks and liberating the shive portions thereof, which continue to fall out from the fibrous portion. Brush 25 materially assists the removal of shive portions adhering to the fiber and loosens said fiber from the corrugations of cylinder 9 so that rolls 22, 23 and so forth may act upon fresh portions thereof and thus break up further shive portions of the stalk. The stalk portions, now comprising fiber with a small residue of shive are freed from cylinder 9 and passed into the bite of rolls 29, 30 by means of brush 830 and thence against cylinder 90 by which they are led upwardly under rolls such as 32, 33, under brush 36, and thence under the succeeding rolls coacting with said cylinder, all similar in character and mode of operation to those described. in coaction with cylinder 9. Also roll 33 by its endwise movement furnishes a cross scrubbing action that rubs the shives from the fiber and rearranges said fiber for more effective treatment by the succeeding means. Then by means of brush 560 the now substantially shine free fiber is directed into the bite of rolls 50, 57 and onto receiving apron 58.

I claim:

In a machine for treating fibrous plants the combination of a pair of rotatable cylinders mounted on parallel axes, a frame mounted for oscillation coaxial with each cylinder, a plurality of rolls mounted in one frame for rolling coaction with the lower portions of one cylinder and a plurality of rolls mounted in the other frame for rolling coaction with the upper portions of the other cylinder, means for synchronously rotating said cylinders, means for oscillating said frames, means for delivering material between one cylinder and its coacting rolls and means for transferring said material from said cylinder to the other cylinder.

Signed this first day of June, 1909, at 13 Park Row, New York, before two sub scribing witnesses.
