To all whom it may concern:

Be it known that 1, CHARLES A. CLARK,- of Auburn, in the county of Cayuga, in the State of New York, have invented new and useful Improvements in Slivering-Machines, of which the following, taken in connection with the accompanying drawings, is a full clear, and exact description.

This invention relates to certain improve ments in feeding and piling attachments for slivering machines as used more particularly in the manufacture of rope from hemp or equivalent fiber, but it will be evident from the following description that the same attachments may be used in the preparation of slivers of any fibrousmaterial and for any purpose where it is necessary to stack or pile loose untwisted strands in relatively small symmetrical and compact space.

Heretofore, so far as I am aware, it has been the invariable custom of rope manufacturers to employ a helper at the delivery end of each machine fordirecting the delivered sliver into a suitable confining space (such as a box or rack), the usual method being to arrange the loose untwisted strands in coils which not only produces a more or less loose and irregular pile requiring a greater amount of floor space for the storage of a given weight of the fiber-but imparts to the strand a certain objectionable twist.

The primary object, therefore, of my present invention is to provide means driven by the machine for laying out or stacking the slivers in layers of uniform length and width as it emerges from the machine without liability of twisting or breaking down at the ends. That is, I have sought to provide an automatic stacker operating in such manmer as to cause the sliver to traverse backward or forward over a predetermined area so that the successive strands will be deposited side by side throughout such area without liability of piling up more in one place than in another.

Another object is to provide an automatic packer or pressing device acting intermittingly but in synchronism with the stacking mechanism when the latter is in such position to permit the operation of the packer.

Another object is to prevent the passage Qther objects and uses relating to specific parts of'the machine will be brought out in the following description.

In the drawings Figure 1 is a side elevation ofthe rear end of a slivering machine showing the automatic stacker or piler and its operating mechanism and also the pack ing device and box in which the sliver is stacked. Fig. 2 is an end view of the stacking and packing mechanism shown in Fig. 1. Fig. 3' is an enlarged central vertical sectional view through the upper portion of the samejdevice taken online 3-3, Fi g. 2. Fig. 4- is' an enlarged rear face view of the upper portion of the oscillatory stacker or laying out device for the sliver and its operating mechanism. Fig. 5 is an enlarged horizontal sectional view through the upper portion of the same device taken on line 5, 5, Fig. 1. Fig. 6 is an'enlarged side elevation of the upper portion of the machine opposite to that shown in Fig. 1 showing more particularly the hand-operated cams for separating the feeding rollers which deliver the slivers from the main guide into the stacking chute. Fig. 7 is an enlarged horizontal sectional view through the packing device and upper end of the packing box taken on line 77, Fig. 1. Fig. 8 is an enlarged horizontal sectional view through the rear portion of the slivering machine showing the gears for transmitting motion from one of the delivery rollers to the countershaft which drives the feeding rollers and other movable parts of the stacking and packing device taken on line 8-8, Fig. 1.

Automatic stacker 0r yivcrr l his stacker or piler is located at the delivery end of the slirering machine as an attachment thereto, and in order that the ssociation may be clearly established, 1 have shown the rear end of a slivering machine A as provided with a pair of feeding rollers a delivering the sliver into a chute B and thence between the additional. pair of feeding rollers b from which the sliver is diverted outwardly into a stationary upright chute or guide 1, the latter being supported in an upwardly and rearwardly inclined position upon a bracket 2 on the rear end of the machine A-.

Mounted on the upper end of the guide chute -lis a framework 3- carrying a plurality of in this instance three, feed rollers 1 5 and 6, the feed rollers and 5 serving to receive the sliver directly from the upper end of the chute l and to divert it rearwardly and downwardly between the feed rollers 5 and 6-, the meeting faces of the latter being located directly over and in vertical alinement with the upper open end of an oscillatory piling or stacking chute 7- which extends downwardly some distance below the ee i rollers 5- and -6 tol octly over the open upper end cn'ng box or frame 8- in which ao is adapted t he tein mrarily its-cited 01. d.

chute is ac apted to be The stack oscillated forwardly and rearwardly and is also movable transversely of the machine r this purpose its ripen" side is connected by a universal joint 5)-- nisaeio to a screw stud -10 whica is iustahly cured to a bracket -1l on too upper end of the guide chute "1* as sh clearly in Figs. 3 and 5, thus per entire chute to be oscillated in any d about the center of the univei pling 9-.

The means for oscillating the "ainstance of a rotary eccentric is rigidly secured to a rotary sh the latter being iournaled in so ings in the frame -3 as shown clearly in Figs. 3, i, and 5, said being surrounded by per i l3 loose thereon and attao rear side of the stacker chute W M by of laterally elongated loop trio with the axis of movement and secured to the opposite si thereof indicated in Figs. 3 and i, the connectio oetween the band l3"- and loop be g to permit the loop -14. to slide freely through the ring or band as the chute is oscillated laterally in a manner presently de scribed. The means for effect, this lerally oscillating movement of the chute 7- consists of rotary shaft journaled in suitable hearings on the 8 transversely of the machine and preferably at the of the chute and provided with a double threaded portion it?- constituting a right and left hand threat with which is engaged a sectional nut l.'. having a cylindrical shank *l8. wis journaled in a yoke -l9., the letter slidable along and upon the, t readed portion of the shaft and is held again t turning by sliding engagement with an underlying guide rod 20 also mounted in the frame -3.

A rock arm 21- has its upper end slidably mounted upon the cross rod 20 a recess in the yoke l9 so as to move laterally with said yoke as the la er is shifted along the shaft 15 by engagement of the nut 17 with the threaded portion 16, the lower end of the rock arm 21 being passed loosely through an elongated loop 2:2 on the rear side of the stacker chute 7 so as to rock said chute laterally or transversely of the machine a s the arm -21 and yoke 19 are similarly moved by the screw 16- and nut 17.

The means for driving the eccent carrying shaft l3 and screw shaft is follows: The lower fe roller -Z')-- on the rear end of the sliver machine is Gilli. mooted by a t ain of I coin:

7; the lower end or which is journal-ed rec in a bearing on the bracket 2- while its upper end is journaled in a corresponding bearing on the frame and is connected by bevel 28* to a horizontal shaft --2S), the latter being also journaled in suitable be 'ngs on the frame 3- and forms a driving shaft for the feed roller -5- mounted thereon.

The shaft 2-9is provided with a pini n 30- driving train of relatively larger gears -31, -32 and 33, the gears and -33 being secured respectively to the eccentric-carrying shaft -l3 and to the screw shaft --15 as shown more clearly in Figs. 5 and 6. These gears -30, -3l, -32 and 33- are, of course, so proportioned as to drive the cam shaft l-3-- and screw shaft 15 at t ieir required speeds, the gear 3l being journaled on a stud --3-ft on the adjacent side of the frame 3 and serves to drive the shafts 13 and 15 in the same directi on.

The reversely cut threads or screws 16 on the shaft -15 acting on the swivel nut 17- serve to reciprocate the yoke 19 and arm -l rectilinearly or parallel with the axis of the shaft -15, this reciprocatory movement of the arm 21- serving in turn to oscillate the chute 7 laterally tlu'ough the medium of its connection 22 therewith and at the same time permits the eccentric -12 to oscillate said chute in a plane at right angles to that imparted to it by the arm 21.

The free end of the chute is, therefore, caused to traverse a n'edetermined area directly over the upper end of the box or stacker frame 8-, the throw of the eccen trio being such as to cause the sliver to he returned back and forth. from front to rear of the interior of said box while the length of the screw l6 and its connections with the chute are constructed so as to lay out the returns of the sliver from side to side within the box with the return strands in close proximity, thereby stacking the sliver symmetrically and filling the entire space within said box, it being understood that the sectional nut -'-17 is automatically reversed at each end of the screw for reversingthe direction of lateral movement of the arm -fll and chute 7 con nected thereto.

The feeding rollers -land -6- are jcurnaled in yielding bearings 35 and 3- spring-pressed toward the feed roller 5 by springs 3 T and 38- to yieldingly hold said rollers l and 6 in contact with the roller for feeding the sliver from the stationary guide '-1- into the oscillatory guide delivery chute .-7-, but it is sometimes necessary to separate said rollers, as for example when passing the sliver between them by hand in the mechtmism.As the loosely stacked in. the manner described within the box 8, it becomes necessary to pack it down at intervals and for this purpose I have provided an oscillatory packer arm l2 fulcrumed at its lower end at -4l-? to a bracket t-itcentrally on the upper end of one side of the box 8 as shown more clearly in Figs. 1 and 2.

T he upper end of the arm -.t2 provided with a cross-bar l5 which is movable into and out of the box against the upper surface of the stacked sliver-to press the same downwardly into the box as the arm l2- is oscillated in the manner presently described.

A crank arm --l7 is fulcrumed on the bracket 4l coaxial with the axis of movement of the rock arm -42 but movable independently thereof and to this crank arm is pivotally attached a rod 48- pass ing upwardly through an apertured lug l9 on the rock arm 4r2-.

A compression spring 50 surrounding the rod 4l8-- is interposed between the shoulder 51 on said rod and the adjacent face of the lug l9 and together with the rod i8 establishes a yielding connection between the crank arm l-7- and rock arm l2- to compensate for 'arying positions which the free end of the rock arm l-2 will assume as the height of the stacked sliver in the box varies, the up per end of the rod l8 being provided with a shoulder 52 for returning the rock arm upwardly.

Any suitable means may be employed for oscillating the packer arm l2 intern'iittingly so as not to interfere with the operation of the delivery chute 7 and for this purpose a cam shaft 53 is journaled in suitable hearings on the bracket l-tand provided with a cam 54l rigid thereon acting against a roller 55 on the crank arm 47 as shown more clearly in Fig. 9 for rocking the arm -l2- laterally and downwardly into thebox -8 against the action of a retracting spring 56.

Secured to the cam shaft 53 is a pulley 57, which is connected by a belt -58 to a loose pulley -59 on the screw shaft .15- so that the action of the packer is synchronized with the lateral movement of the delivery chute 7 and is adapted to move in a plane parallel with said screw shaft.

Owing to the fact that the free end of the packer arm -l2 moves from one side downwardly into approximately the center of the and that the lateral movement of the delivery chute and sliver do liver-ed thereby into the l'JOX are caused to move across the path of movement of the free end of the packer arm, it becomes necessary to prevent the movement of said packer arm when the delivery chute is moving from its central position toward the site of the box to which the packer arm is attached and for this purpose 1 have provided the pulley 59- with a clutch face 60 adapted to be engaged by a sliding clutch section Glwhich is splined or feathered upon the screw shaft -15, the sliding clutch 61 being operated by a shifting member 62 riding in an annular groove on the clutch section 61- and pivoted to lever 63 which in turn is fulcrumed intermediate its ends on the frame 3 and is pivotally connected to a horizontally sliding rod 6 l-, the latter being guided in apertured bearings 65 on said frame parallel with the screw shaft -15.

A collar -(i6 is loosely mounted on the screw shaft -l5 at the right hand end of the screw 16, Fig. 5, to slide thereon and is adjustably secured by means of a set screw 67 to the sliding rod -64. to move therewith. A coil spring o8 surrounds the shaft 15 between the collar -66 and adjacent side of the frame 3-- nearest the gear 33 for normally holding the collar 66 in the path of movement of the yoke -19- and also for normally holding the clutch section 6l out of engagement with the corresponding clutch face 60 of the pulley 59-.

The action of the packer, therefore, depends upon the movement of the collar 66 against the action of the spring 68 by the yoke 19, said collar being adjusted along the screw shaft 15 and rod 6 lto cause the operation of the packer arn 4l2 only while the stacker chute 7 is moving from its central po sition to its position at the right hand of Fig. 2 and back again, during which time the collar 66 will have been shifted by the yoke 19 along the screw spindle 15 against the action of the spring -Gc-. the latter serving to automatically return the collar and thereby releases the clutch from operative engagement with the pulley 59 as soon as the delivery chute 7- returns to a predetermined position toward the packer arm 4.J.

Starting and stopping mechcmz'sm.-ln Figs. 12 and 13, l have shown a main driving shaft 'E as provided with tight and loose pulleys -69 and 70 for receiving a belt 7 1" which is shifted from one pulley to another by means of a shifter loop -72 mounted on one end of a bar 73, the latter being guided in transverse ways 7et in the opposite sides of the main supporting frame of said machine.

A rock shaft d6 is journaled in bearings upon and lengthwise of the machine so as to extend to the rear end thereof where it is provided with a hand lever 75- rigid thereon for turning said rock shaft by hand against the action of a retracting spring 76*, the latter being interposed between the handle and adjacent bearing for the shaft as shown in 12.

friction is transmitted from the rock shaft -l-6 to the belt-shifting bar 73 by means of a crank arm 77 having a slot -7S-- for receiving a pin -79- on the shifting bar whereby, as the rock shaft -el6 is operated by the handle -75 to tension the spring76,the bar 73 will be shifted to the left as shown in Fig. 13, thereby shifting the belt from the loose pulley onto the tight pullev in which posi tion the bar Z3- will be automatically locked by detent -80 engaging in a notch -81 in the underside of the bar as shown in Fig. 1 L, said detent consisting, in this instance, of a lever fulcrumed interme diate its end at 82 to the adjacent portion of the main supporting frame A of the machine. This detent is weighted so as to automatically engage in the notch -S1.

Suitable devices are provided in different parts of the machine actuated by knots or extra heavy quantities of the sliver during its passage through said machine for tripping the detent 80 One of these trippinedevices is arranged to coact with the upper feed roller b on the rear end of the machine and for this purpose such roller is mounted in vertically yielding bearings 83 normally under spring tension of the springs 84 so that in case a knot or extra heavy quantity of material should be caught between the feeding rollers b. the upper one will be raised against the action of the spring -8-. This liftingmovement of the roller is utilized to trip the detent 80 by connecting one end of said lever to the lower end of an upright rod 8Z- having its other end provided with a hook S6 engaging the upper side of the shaft of the upper roller bas shown more clearly in 12 and 13, whereby, as the roller is raised in the manner just previously described, the detent 80 will be forced from holding engagement with the beltshifting bar -73 thereby allowing the spring 76 to automatically rock the shaft 46 for returning the shifting mechanism to its starting position with the -Z but it sometimes happens that the elite will pack up or bunch in the chute and th prevent the delivery of such sliver in proper form to the stacking device and in order to prevent such condition, a curved ruck arm -88 is pivotally mounted in the upper front end of the chute B with its convex de facing the bottom thereof, leaving s cient clearance between the curved arm -SS- and. bottom of the chute for the free passage of the sliver in its normal condition through said chute. This curved arm -SS is preferably secured to rock shaft 99 and is provided with a crank 'arin 90 connected by a cable )lto the hook S6 on the upper end of the rod -85, the central portion of the cable being passed over a sheave 92 so that in case the sliver should bunch or collect while passing through the chute, the extra thickness will raise the arm 88 and thereby lift the rod 85 through the medium of the cable 91 to effect the tri 'iping of the detent 80 in a manner sin'iilar to that previously described. It is advisable, however, to prevent the entrance of these knots or heavy thickness of sliver into the machine or before reaching the chute B or rear end roller b and for this purpose I have shown two feeding rollers F forming a part of the ordinary sl'vering machine and located near the front end thereof, the upper roller l* being mounted in a vertically yielding bearing f-normally spring-pressed downwardly by a coil spring and permitting the upper roller to rise against the action of said spring in case a knot or extra heavy thickness of sliver should become caught between the rollers 'F. This upward movement of the upper roller l* is also utilized to trip the detent -S0 by engaging the upper side of the shaft of the upper roller with a shoulder 95 which is pivoted to one end of the lever This lever is fulcrumed intermediate its ends at 97 upon a portion of the main supporting frame -A and is pivotally connected to the upper end of a vertical rod 98-- having its lower end pivotally connected to a crank arm 99- on a rock shaft -100, said rock shaft being journaled in suitable bearings l01 on the main supporting frame parallel with the rock shaft 74l and extends to a point in proximity to the end of the detent 80 to which the end of the upright rod 85 is detached where it is provided with a crank "arm l02 extending under the loweredge' of said detent asshown more clearly in Fig. 16. v

- The crank arms 99 and 102 on the rock shaft -100' project in opposite directions from said shaft so that when the shoulder -95 is lifted by the upward movement of the upper free roller f it causes a corresponding downwardmove ment of the rod 98-- through the movement of the lever 96, thus rocking the shaft l00 and causing the crank arm l02- to lift the adjacent end of the detent 80, thereby tripping said detent from holding engagement with the beltshifting bar 73 and allowing the spring 76 to return said bar to its normal position with the belt -71 in engagement with the loose pulley for stopping the machine.

The operation of my invention will now be readily understood upon reference to the foregoing description and the accompanying drawings, but it will be evident that the mechanisms for stacking and packing the sliver and for starting and automatically stopping the machine as affected by the presence of knots or extraheavy thicknesses of sliver in different parts of the machine may be modified materially without departing from the spirit of this invention and, therefore, I do not limit myself to the structure herein shown and described.
