This invention relates to an air hackling-attachment for scutching machines, and has for its primary object to provide, in a manner as hereinafter set forth, an attachment of such class by means of which fibers-passing from the scutching blades of the machine may be hackled by air to remove loose particles from thefibers and to free the lat ter from kinks and snarls, thereby restoring the-fibers e to substantially their original lengths and reducing to a minimum the dam..- age done to the fibers in hackling the same. A further object of .the'inv'ention is to provide an air hackling attachment of the character aforesaid by means of which fibers may be guided from scutching blades for the tips to scutching blades for the butts, thereby materially reducing the cost of hackling through R elimination of waste and acceleration of output.

With the foregoing and other objects in view the invent on consists of the novel construction, comblnation and arrangement of parts as hereinafter more particularlydescribed, and as illustrated in'the' accompanying drawings whereinis shown an embodiment ofthe invention, but it is'tobe under stood that the description and drawings are n to be taken'as illustrative, and that the invention is intended tobe limited only by the scope of the claims hereunto appended.

In the accompanying drawings wherein like reference characters are employed to designate like parts throughout the several views:

7 Figure 1 is a longitudinal, verticalsection through a scutching machine equipped with my attachment. 7

Figure 2 is an end elevation thereof. Figure 3 is a transverse section taken at a point indicated by the line 3-'3 of Figure 1,

Figure 4 is an enlarged fragmentaryelevation of my attachment. I 4 Figure 5 is a view similar to F igure lbut taken at a right angle thereto. i Figure 6 is a section taken on the line 66 of Figure 4. f y i Referring to thedrawings in-detaiLthe numeralsl' and 2 respectively indicateza pair of scutching chambers through whic'hfibcrs, such as 3 areadapted to be-passed; When passing through the chamber 1, the fibers 3 arejsuspended'from afconveyor 4 with tips of the fibers hanging down, and are subjected on opp'osite'side's thereof to the action of a paii' of

scutching elements

5 and 6 extending longitudinally of the chamber 1 and jou'rnaled in'the end Walls 7 and c8 of the latter. The

scutching elements

5 and 6 rotate in opposite directions, and *each" includes: a plurality of radiallypro-jec'tingblades 9. The path of movement of the blades of the element 5 overlaps thatof the blades of the element 6, andthe

elements

5 and 6 are synchronized ina manner to bring the blades of theelement 5 into engagement with the fibers alternately with respect to the'bladesof the element 6. Theblades 9 strike the fibers with a downward-motion, thereby removing from the fibers, broken straw, hurds, 'sh'iveS and the like; L e

From the chamber l the' fib'ers are passed through an opening 8 in the end'wall 8' to'the chamber'Z, wherein the fibers are suspended from aconveyor 10 with the butts of the fibers" hanging down 'andpassing between scutching elements 11 journaled in the. wall '8 common to the

chambers

1 and 2, and the outer end wall. 12 ofthe chamber 2. The scutching elements 11 are similar to the

scutching elements

5 and 6 and include blades 12. After passing between the elements 11, the fibers are delivered from the chamber 2 through an opening 13' in the wall 12; Owing to the action ofthe blades 9, the'- tips of thefibershave a tendency to snap upward- 1y when released by said'blades, thereby kink ing and snarling the fibers, whereby the length of of the fibers normally would beinsufilcient to reach the conveyor 10 be-. fore being released from the convey'or, 4, consequently causing-an enormouswaste offibers at the point of transfer from the chamber 1 to the chamber 2. Likewise the action of a} thebl'ades12 have a tendency to kink and snarl'thefibers when the latter are released from the blades 12. If such kinks and snarls are combed out mechanically, many of the Y fibers are broken, thereby causing .aifurther 1-00 tributor 28.

waste. By the employment of my attachment, the waste caused by the kinking of the fibers when released from the blades 9 and 12 is substantially eliminated.

The attachment includes an air pressure conduit 13 which is adapted for connection with a source of supply, such as a blower 14, or air compressor. Leading from the conduit 13 is a branch 15 with which is connected a rotatably adjustable distributor indicated generally at 16. The distributor 16 includes a vertical trunk portion 17 which extends from the coupling 15 and is provided with a pair of oppositely extending, horizontally disposed

branches

18 and 19 which extend transversely of and project beyond conveyor 4%.. Slightly outwardly from a side edge of the conveyor 1-, the branch 18 is formed with a downwardly extending continuation 20 which merges into a horizontally extending portion 21 disposed at a right angle to the branch 18. The portion 21 merges into a vertical portion 22 which terminates in a nozzle 23 having its outlet arranged in a manner to discharge air onto the fibers at a downward inclination of substantially 45 and across the same at an angle of substantially 5.

The branch 19 is provided with a vertical continuation 24c, horizontal portion 25 and vertical. portion 26 similar to the corresponding portions of the branch 18. The portion 26 merges into a nozzle 27 having its outlet arranged in a manner to discharge air onto the fibers at a downward inclination of substantially and across the same at an angle of substantially 10. Owing to the angular relation with respect to each other of the streams of air being discharged onto the fibers, the latter will be combed by the air to straighten the fibers and to remove hurds and the like therefrom. Owing to the angular relation of the streams of air with respect to the direction of travel of the fibers, the tips of the latter will be actuated toward the conveyor 10 which grips the tips of the fibers just prior to the release of the butts of the fibers by the conveyor 4. Since the fibers will be extended at a downward and rearward inclination by the action of the air streams from the

nozzles

23 and 27, the conveyor 10 is locatcd in a lower plane than the conveyor 4 and in spaced relation to the latter. The parts 17 to 23 of the distributor 16 are adjustably connected with respect to each other, and the trunk portion 17 is adjustably connected with the branch 15 of the conduit 13.

In order that the fibers may have removed therefrom the kinks and sna-rls caused by the scutching blades 12 within the chamber 2, the conduit 13 is provided with a second air distributor 28, which is the same in every respect as the distributor 16 and will not be specifically described, as the description of the distributor 16 also may be applied to the dis- Owing to the action of the distributor 28, the fibers are delivered from the conveyor 10 in a straight and unbroken condition.

It is thought that the many advantages of an attachment in accordance with this invention will be readily apparent, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the size, shape and arrangementof parts may be resorted to, so long as such changes fall within the scope of the invention as defined in the appended claims.
