Application led August 10, 1929. Serial No. 885,014.

This invention relates to a piling mechanism and more particularly to a mechanism for piling a sliver of fiber as it comes from a ber working machine.

The receiving and piling mechanism is adapted for use in connection with any and all types of machines for working various kinds of fiber which may be of any composition such as animal or vegetable.

The piling mechanism is particularly adaptable for use in handling slivers in va.- rious forms, from or to, carding machines, drawing machines, roving machines, spinning machines, twisting machines and other well known types of fiber working machines.

The invention provides for forming a particularly compact pile of sliver of fiber which may be removed as a. unit without substanial deformation. The twist of the fiber is neutralized during piling so that it may be removed from the pile in an untwisted condition without requiring special care or attention.

This is accomplished by feeding a sliver il of iiber to an oscillating table and imparting a predetermined wave to the liber so that it falls in the form of eccentric, slightly curved chords which are folded back and forth across the table. The wave is impartr ed to the sliver in such a direction that the folds or chords are of uniform length and completely fill the table so that the finished pile has an even contour and'is in compact form.

The invention also consists in certain new and original features of construction and combinations of parts hereinafter set forth and claimed.

Although the novel featureswhich are believed to be characteristic of this invention will be particularly pointed out in the claims appended hereto, the invention itself, as to its objects and advantages, the mode of its operation and the manner of its organization V' may be better understood by referring to the nism;

Fig. 6 is a section taken on the line 6-6 of Fig. 2 showing the mechanism for oscillating the spout; and

Fig. 7 is an enlarged detail of the connecting link to the spout.

Like reference characters denote like parts in the several figures of the drawings.

In the following description and in the claims parts will be identified by specific names fork convenience, but they are intended to be as generic in their application to similar parts as the art will permit.

Referring to the drawings more in detail the invention is shown as applied to a piling-` mechanism which may be employed in connection with ber working machines 10 of any and all types. Each sliver 11 leaving liber working machine 10 is illustrated as formed Vfrom a pair of slivers 12 which are taken from rolls or piles 13. It is obvious, however, that any number of slivers may be operated on by the fiber working` machine and used to produce slivers 11 which are lto be piled in accordance with the present invention.

Referring more particularly to Figs.` 1 and 2 the invention is shown as applied to receivers 14 whichl are adapted 'to receive slivers 11 which are directed by spouts l5 thereto. Receivers 14 comprise rotary tables which are mounted for rotary movement onshafts 21 and U-shaped shields 22 which partly enclose said tables and serve to conline the slivers during the piling operation.

VChutes 15 (Fig. 2) are pivotally mounted as Vat 25 on the frame 26 of the ber/working machine. Said frame also supports driving shaft 27 carrying a plurality of feed rolls 28. Shaft 30 is journalled in bracket 31 secured in framey 26 and carries a plurality ofV goscillate about their' centers.

presser rolls 32 which are in engagement with the various feed rolls 28. Cooperating gears 33 and 34 on shafts 3() and 27 respectively cause the necessary rotation of

rolls

28 and 32 for feeding the slivers 11 onto chutes 15.

Shaft 27 terminates in a beveled gear 35, cooperating with a beveled gear 36', carried by shaft 37 which is journalled in suitable bearings secured to frame 26. Gear 38 carriedfby shaft 37 drives the gear 39 which in turn causes rotation of crank 40. Crank 40 (Fig. 6) is provided with a pin 41 on which is mounted connecting rod 42 which is also pivoted to reciprocating rod 43. Rod43 isv provided with a plurality of pins 44 (Fig. 7) carried on brackets 45 which are adjustably secured to said rod 43 by means of bolts 46. elongated slots permitting transverse adjustment of bracliets 45 to permit proper alignment of pins 44.

Each pin 44 engages an elongated slot 47 in arm 48 which is secured to the underside of a chute 15 in any convenient manner. It is to be noted that the rotary movement of crank 40 causes reciprocating movement of rod 43 which through arms 48 causes a similar reciprocating movement of chutes 15 about pivots 25.

Chutes 15 may also be provided with hori- Zontal pivots 50 (Fig. 2) by means of which their angles of inclination may be varied as desired. l Y

The lower end of shaft 37 is provided with a worm 51 (Fig. 4) cooperating with a worm gear 52 carried on shaft 53 (Fig. 2), which also carries sprocket 54. Chain 55 (Figs. 2 and 5) to which connecting rod 56 is secured as by pin 57, is passed over sprocket 54 and idler sprocket 58. Connecting rod 56 is pivf otally connected to rack 59, which engages gear wheels 60, meshing with gears 61 which are mounted on shafts 21.

It is to be noted that the rotary movement of shaft 37 causes chain v55 vto pass over sprockets 54 and 58 in the direction of the arrow'of Fig. 5 and through connecting rod 56 causes oscillatory movement of rack 59. This rack drives Agear wheels 61, shafts 21 and tables 2O thereby causing said tables'to ship ofthe various' gears is preferably so chosen that tables 20 oscillate through an angle of 360", although other angles of oscillation may be selected if it is found desirable in a particularcase.

In the operation of the above describedV mechanism slivers 11 are fed over chutes l5 by the action of feed rolls 28 and presser rolls 32. The slivers are given an oscillatory motion in the direction of their greatest width by the oscillatory motion of the .chutes whereby they are deposited on tables 20 in the form of folded waves. Tables 20 are slowly oscillated Yas the slivers are fed thereto. Hence the waves are progressively dis- The relationf placed about the periphery thereof and take the form of eccentric, slightly curved chords. Any twist which occurs in the fiber while the table is turning in one direction is neutralized by a corresponding reverse twist as the table rotates in the opposite direction.

Since the wave motion is imparted to the sliver in the direction of its greatest width, the natural stiffness of the sliver in this direction causes themotion to be transmitted uniformly tothe material adjacent the pile whereby the chords are formed of substantiallyequal length and a smooth contour is imparted tothe pile. In addition, the pile contains the maximum amount of fiber per unit of volume.

The rates of movement of tables 20, chutes 15 and feed rolls 28 are so related that, as the sliver is fed down a chute 15, it is piled on the revolving table in the desired form and the folds are caused to extend over substantially the entire table. It is to be noted that as the pile rises the sliver becomes displaced toward the center of the table due to the decrease in length of the unsupported section, thereby causing the hole between the various chords, which are shown in Fig. 3, to progressively decrease in size toward the top of the pile.

The pile of sliver thus formed is composed of alternate folds extending in opposite directions with the twist of the various folds so neutralized that the sliver may be withdrawn from the pile and applied to any desired machine, in an untwisted condition without requiring attention. It is of comparatively regular contour and possesses suficient strength to permit removal as a unit without danger of becoming deformed or en tangled.

"While certain novel features of the invention have been shown and described and are pointed out in the annexed claims, it will be understood that various omissions, substitutions and changes in the forms and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention. It is obvious that in certain types of work the chute constructed in accordance with the present invention may be employed with other types of tables and that the extent and speed of the oscillations of the table may be varied as required. In certain instances where the twist of the fiber is of less importance a continuously rotating table may be desirable.

What is claimed is:

1. In apiling mechanism, a rotary table. means for causing oscillatory movement thereof, a chute for directing a sliver on said table, and means for oscillating said chute about a substantially vertical axis whereby the sliver is automatically oscillated in a direction of its greatest width as it is fed to IOL the oscillating table and is caused to be piled in a series of eccentric chords of substantially. uniform length, the relative movement of the chute and table being such that successive chords are angularly displaced and disposed on the same side of the axis of the table in a substantially toroidal formation made up of a plurality of alternately superposed helices.

2. In a piling machine including a plurality of chutes, a plurality of rotatable tables, a gear associated with each of said tables, a rack cooperating with said gears and means for causing an oscillatory movement to said rack comprising an endless chain, a connecting rod pivoted on said chain and secured `to said rack and means for causing continuous movement of said chain.

3. In a piling mechanism, a table mounted for rotary movement about its axis, means for causing oscillatory movement of said table about said axis, a chute for directing a sliver onto said table and means for oscillatin said chute in a direction of the greatest Wi th of said sliver, said oscillating chute and said oscillating table being so related that the sliver is fed onto the table and piled thereon in a serious of eccentric chords of substantially uniform length, successive chords being angularly displaced and disposed on thek same side of the aXis of the table whereby a substantially toroidal formation is obained made up of a plurality of alternately superposed helices and the twist of the various portions thereof is neutralized whereby the sliver may be removed in an untwisted condition.

4. The method of piling a continuous sliver which comprises feeding said sliver onto a platform at a uniform rate while imparting to said sliver an oscillatory motion inthe direction of its greatest width and simultaneously causing said platform to oscillate about its axis whereby said sliver is piled in a series of eccentric chords of substantially uniform length, successive chords being angularly displaced and disposed on the same side of the a-Xis of the table whereby a substantially toroid formation is obtained made up of a plu` rality of alternately superposed helices and the twist of the various portions thereof is neutralized whereby the sliver may be removed in an untwisted condition.

In testimony whereof I have hereunto set my hand.
