EPPA. H. RYON, 0F WALTHAMfMASSACI-IUSETTS, ASSIGNOR TO CBOMPTON & KNOWLES LOOM WORKS, 0F WORCESTER, MASSACHUSETTS; A CORPORATION OF MASSACHU SETTS'.

To all whom it ma concern;

- Be it known t at I, EPrA H. RYoN, a citizen of the United States, residing at Waltham, in the county of Middlesex and State of Massachusetts, have invented a new and useful Winding-Machine, of which the following is a specification.

This invention relates to a winding machine particularly designed for winding the long spools of yarn which are used in weaving moquette carpets.

Each such spool is commonly provided with a plurality of different color yarns arranged in a definite order to reproduce one element of thepattern. This pattern element is often exactly repeated but in reverse order on a second spool to complete the figure, where the figure is symmetrical and wider than a single spool.

It is one object of my invention to provide an improved winding machine of the general type above described, in which the direction of winding may be readily reversed to permit the winding of either right same time the use and movement of heavy.

mechanism is avoided. To the attainment of this object, in the preferred form of my invention, I provide a friction device for strongly resisting outward movement of the upper roll while the spool is being wound, together with means for readily disconnecting and releasing the friction when changin rolls. 5

it is very desirable that the yarn should be brought to the spool at such an angle that it will engage the spool and the driving roll substantially at the bight'of the spool WINDING-MACHINE.

and roll, and particularly that it should not be .drawn over the roughened surface of the roll.

Accordingly, a third object of my invention is to provide a vertically adjustable comb and yarn guide by means of which the yarn may be delivered at a suitable angle when the spool is being wound in either direction.

Further features of my invention relate to an improved device for removing the yarn retaining wire from a full spool; to improved mechanism for supporting and driving the movable upper roll; to a novel releasing device for the pressure roll; and to improved mechanism for driving and controlling the several parts of the machine.

My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

A preferred form of my invention is shown in the drawings, in which Figure 1 is a plan view of my improved machine;

Figs. 10, 11 and 12 are diagrammatic views showing different positions of the pressure roll releasing device;

Fig. 13 is a detail view showing the raised position of the pressure roll, and

. lowered position of the comb and guide rod.

The general operation of the machine is perhaps best shown in Fig. 4 in which the yarn threads Y are shown as they pass through suitable guiding devices to the spool S resting upon two supporting rolls 20 and 21, and held firmly in contact therewith by an upper pressure roll 22. The rolls 20, 21 and 22 are provided with suitable driving mechanism and rotate the spool S under pressure, thereby winding the yarn compactly thereon. When the spool is filled, the pressure roll 22 is swung upward to the position indicated in Fig. 13,. thus permitting removal of the full spool and insertion of an empty spool.

Having described the general purpose of the machine, I will now describe the detail construction thereof.

My improved winding machine comprises side frames 23 and 24 (Fig. 2) connected by cross girts 25 and a tie rod 26. The rolls 20 and 21 .are mounted in fixed bearings on the frames 23 and 24 and are provided with pinions 27 and 28 (Fig. 3) meshing with an intermediate gear 29, which in turn engages a pinion 30 (Fig. 2) 'fixed on a cross shaft 31 also supported in hearings in the side frames.

A pair of reversed bevel gears 32 and 33 are loosely mounted on the shaft 31 and each engages a driving bevel gear 34 fixed to the upper end of a vertical shaft 35 rotatable in bearings 36 and 37, and provided at its lower end with a bevel gear 38 e5;- gaged by a bevel gear 39 fixed to the main shaft 40, also rotatable in bearings sup? ported by the side frames 23 and 24. A driv' ing pulley 41 is freely rotatable upon the shaft 40, the extended hub of the pulley 41 having a groove 42 formed therein and also having a pinion 43 fixed thereto. A friction head 44 is fast on the outer end of the shaft 40, and the pulley 41 may be moved axially to frictionally engage the head 44 by means of a starting lever 45 secured to one end of a rod 46 (Fig. 4) pivotally mounted in bearings 47 and 48, and having a branched arm 49 fixed thereto and engaging .a yoke 50 positioned in the groove 42. The upper end of the starting lever -15 is provided with a block 31 which may be readily engaged by the knee of the operator. When the block is pressed'to the left, as viewed in Fig. 2, the pulley 41 is moved to the right to engage the friction head 44 and thus put the winding mechanism in operation.

A second starting lever 52 (Figs. 2 and 3) is mounted on a stud 53 supported by the frame 23, and is connected by a link 54 (Fig. 2) with the starting lever 45, the link being connected below the pivot of the lever the hub of the lever 52 is so connected tothe hub and to a fixed part that it tends to separate the pulley 41 and head 44 when the levers 45 and 52 are free.

The bevel gears 32 and 33 (Fig. 2) are provided with clutch teeth on their inner faces, and a toothed clutch collar 55 is keyed to the shaft 31 and is slidable thereon to engage either gear. The collar 55 is grooved to receive pins 56 (Fig. 3) extending inward from the forked ends of an arm 57 mounted on a rod 58 supported in bearings 59 and 60 secured to the frame 23. A hand lever 61 is fixed to the opposite end of the rod '58 and extends to the side of the.

machine within convenient reach of the operator. By raising or lowering the hand lever 61, the clutch collar 55 may be caused to engage either one of the bevel gears 32 and 33, and the winding rolls may be thus revolved in either direction. A cam lug 62 (Fig. 3) maintains the lever 61 in either raised or lowered position.

By the mechanism thus far described, the

rolls 20 and 21 may be started and stopped at will, and may be caused to rotate in either direction.

I will now describe the mechanism for driving the upper pressure roll, for yieldingly resisting upward movement thereof during the winding operation, and for per mitting easy removal thereof when a spool is tobe replaced.

The roll 22 is mounted in bearings 63 and 64 (Figs. 1 and 3) integral with segment gears 65 and 66 loose on a shaft 67 secured in . bearings 68 and 69 in the upper part of the frames 23 and 24. A hand lever 70 is fixed to each segment gear 65 and 66, these levers extending substantially horizontally and rearwardly when the pressure roll engages an empty spool, as shown in Fig. A pinion 71 (Figs. 1 and 3) is loose on the shaft 67 and is driven by engagement with the pinion 28 on the roll 21. The pinion 71 in turn engages and drives a pinion 72 on the roll 22, and as the'pinion 71 is mounted upon the 'axis around which the roll 22- swings with the segment gears 65 and 66, continuous driving engagement is maintained between the pinion 72 on the roll 22 and the pinion 28 on the roll 21. The three rolls 20, 21 and 22 are thus rotated in thethe segment gears and 66 are rotated by shown in Fig. 13. As the roll 22 is not very heavy, this operation is easily performed.

The weight of the roll is not sufficient, however, to properly compress the yarn as it. is wound on the spool S, and I have made special provision for yieldingly' resisting upward movement of the roll during the winding operation. Thismechanism is best shown in Figs. 1 and 3 in which pinions 7 3 and 74 are shown mounted on a shaft 75 rotatable in bearings 76 and 77 on the frames 23 and 24, said pinions engaging the segment gears 65 and 66 respectively.

A long sleeve 78 (Fig. 1) is loosely mounted on the shaft 75 and is provlded near one end with a segment gear 7 9 (Fig. 3) engaged by a rack 80 fixed to the upper end of a rod 81 which in turn is pivoted at its lower end .to a lever 82 pivoted at 83 on the frame 23. The shaft 75 is provided with a collar 84 fixed thereon near its center and having a single tooth 85 formed on it periphery. The sleeve 78 has an arm 86 at t e' opposite end from the segment 79, said arm being provided with a stud 87 on which a weighted pawl 88 is loosely mounted, which pawl is adapted to engage the tooth 85 under certain conditions.

An adjustable guide roll 89 (Figs. 1 and 3) holds the rack 80 in engagement with the segment gear 79, and a relatively light weight 90 on the rod 81 normally holds the )awl 88 in engagement with the tooth 85.

he lever 82 extends rearwardly beyond its pivot 83 and is provided with a foot piece 91 by which the rear end of the lever may be readily depressed by the operator.

A friction pulley 92 is fixed to the lever 82'and is engaged by, a friction band 93 having one end secured to the frame at 94: and the other end adjustably connected to one arm of a lever 95 pivoted to the frame 23 at 96. The friction between the band 93 and the pulley 92 may be adjusted by connecting the band to different notches in the lever 95 or by adjusting the position of a weight 97 along the lever. The extended rear end of the lever forms a. convenient handle for manually relieving the friction.

I will now describe the operation of this part of my machine. Assuming that the winding of a spool S has been completed, the

roll 22 will he we been forced upward to the position shown in full lines in Fig. 13, and

the position of the pawl 88 will be as shownin Fig. 11.

If the friction is relieved and foot pressure is applied to the lever 82, the pawl 88 may be easily moved slightly in the direction of the arrow a in Fig. 11 so that it will be free from the tooth 85 whereupon the weight of the pawl will cause it to assume the position shown in Fig. 12, disconmeeting the shaft 75 from the sleeve 78. The roll 22 can then be swung upward to permit changing of the spools, entirely independently of the friction mechanism by which pressure has been previously applied to theroll.

When the roll is returned to operative position and engages a fresh empty spool, the tooth 85 will be found in the position shown in Fig. 10. Foot pressure onthe lever 82 readily moves the pawl 88 to the positionalso shown in Fig. 10, and the weighted lever 95 may then be raised manually to momentarily release all friction from the pulley 92, whereupon the weight 90 (Fig. 3) will slightly rotate the sleeve 78 to cause the weighted pawl 88 to again engage the tooth 85. The parts are thus restored to operative position, and the roll 22 can be thereafter raised only by overcoming the friction on the pulley 92. The position of the tooth 85 near the longitudinal center of the shaft 75 causes the frictional resistance to be equally applied to each end of the roll 22.

The pressure upon the spool is thus caused by frictionally resisting the necessary upward movement of the pressure roll as the diameter of the spool increases, rather than by using a heavy weight or other active force to apply direct pressure to the spool. By avoiding the necessity of raising and releasing heavily weighted parts, the labor of operating the machine is much reduced.

As the yarn approaches the spool S, it is important that it should lead directly to the bight between the spool and theroll, and particularly that it shall not engage the rough surface of the roll for any considerable distance before being wound upon the spool. VVhen the parts are rotating in the direction of the arrows shown in Fig. 4, the yarn is fed between the spool S and the roll 20 and must be delivered thereto at the steep angle indicated in Fig. 1. When, however, the rolls are turned in reverse direction as indicated in Fig. 14, the yarn is received between the spool S and the roll 22 and must be led thereto at a much smaller angle to the horizontal.

In order to adapt my machine to successful operation in either direction I have provided means for raising and lowering the guide rod 100 and comb-101. The details of this mechanism are best shown in Figs. 2 and 7 in which it will be seen that a bar 102 which supports the rod 100 and comb 101 is mounted in vertically movable frames 103 and 104. These frames are suitably guided and are each provided with rack teeth 105 engaging pinions 106 fixed on a shaft 107 rotatably mounted in bearings 108 and 109 on the side frames. The shaft is manually roand guide rod coeperate with a spool being wound as indicated in Fig. 14, and when raised to the dotted line position in Fig. 7

' they coeperate with a spool being wound as indicated in Fig. 4.

I have found that it is desirable to traverse the comb during the winding operation, and for this'purpose I have provided the traverse mechanism shown in Figs. 2 and '8. An upright lever .114 is mounted on a fixed pivot 115 and at its upper end has a'pin and slot connection with the bar 102 which supports the comb and guide rod. The lower end of the lever 114 engages a cam or eccentric 116 mounted on a stud 117 secured to the loom side 23. A worm wheel 118 is fixed to the hub of the eccentric 116 and is driven by a worm 119 formedfon the end of the shaft 31. The eccentric. 116 is thus slowly rotated and provides a limited traverse motion for the comb and guide rod. A spring 120 2) moves the comb and rod in the opposite direction and holds the lever 11.4 in engagement with the eccentric 116. The slotted connection between the lever 114 and the guide bar permits vertical adjustment of the comb as previously described. The extent of traverse is slightly increased'as the comb is raised, but the distance of the comb from the rolls is also increased so that this Variation in traverse is found desirable rather than otherwise.

A spool S is shown partly in section in Fig. 5, this view also showing the locking wire 121 by which the yarn ends are secured to the barrel of the empty spool. The barrel is slotted longitudinally, and the yarn ends are secured by forcing the wire 121 into the slot and thus clamping the yarn between the wire and the walls of the slot. In practice, a full spool is removed from winding position, an empty spool is inserted, and the yarn ends are secured to the new spool by means of the locking wire 121 before the yarn is severed from the full spool.

It is desirable that the locking wire should be withdrawn after a spool is wound and I haye accordingly provided improved mechanism for withdrawing the wire by power, .which'niechanism is anessential part of m machine.

At the front of the machine, as shown at the top of Fig. 1, I have provided guide ways 123 which form the sides of a slot through which a traveler 124 may be drawn longitudinally. The traveler is provided with a vertically slotted extension 125 (Fig.

5) adapted to engage the headed end 122 of the .wire 121 when the end of a full spool is supported on a projection 126 at the side of the machine. A chain 127 is connected at one end to the traveler 124 and passes around a guide pulley 128 rotatable on a fixed pivot 129. The opposite end of the chain is connected at 130 to a pulley 131 fixedto a shaft 132 (Fig. 4) rotatable in bearings 133 and 134 mounted onthe frame The shaft 142.is also rotatable in the bearing member 139, and has a gear 143 secured to the opposite end thereof and engaging the pinion 43. This pinion, as previously described, is fixed to the driving pulley 41 and is continuously rotated therewith. With these connections, it will be seen that the bevel gear 135 on the shaft 132 is continuously rotated with the driving pullev 41. l

A collar 144 (Fig. 6) is fast on the f shaft 132, and a second collar 145 is slidable thereonand is provided with a stud 146 extending through a hole 147 in the. collar 144 and adapted to engage a corresponding hole 148 .in the loosepinion 135. The collar 145 is groovedto receive a forked arm 149 (Fig. 2) fixed to the upper end of a vertical shaft 150supported in bearings on fixed collar 144 and causes the stud 146 to enter the hole 148 in the rotating bevel gear 135. The shaft 132 is thus placed in rotation, winding the chain 127 about the pulley 131 and drawing the traveler 124 along the slotted guide way to the opposite side of the machine. By this mechanism the wire 121 may be mechanically withdrawn from the full spool.

It is essential that rotation of the shaft 132 shall cease asthe traveler approaches the opposite end of the slot, and for this purpose I have provided a flexible connection or chain 153 (Fig. 5) passing over a fixed guide pulley 154 and connected to the traveler 124. A stop 155 is adjustably se-. cured to the member 153, and when the traveler approaches the right hand limit of travel, the stop-155 engages an arm 156 of a weighted releasing bell crank mounted upon a fixed pivot 157 and having a downwardly projecting arm 158 (Fig. 4) connected by a link 159 to the forked arm 149. When the stop 155 engages the arm 156 and moves the same upwardly, the arm 158, link 159 and arm 149 are moved to the left as viewed in Figs. 4 and 6 withdrawing the pin 146 and preventing further rotation of the pulley 181. A weight 160 (Fig. 5) is attached to the 'end of the flexible member 153 and serves to restore the parts to initial position as soon as the clutch shown in Fig. 6 is disconnected.

Having fully described the details of construction of my improved winding machine,

it is thought that a brief general statement of operation will be sufiicient to enable those skilled in the art to fully understand the operation thereof.

An empty spool being placed between the rolls as shown in Figs. 4 to 14, the comb and guide rod are adjustable vertically in accordance with the desired direction of rotation, and the machine is then started by pressure upon one of the levers 45 or 52. As long as the driving pulley 41 is held in frictional engagement with the head 44 the winding operation continues, the pressure roll 22 being gradually forced upward by the increasin diameter of the spool against the frictiona resistance of the band 93 applied through the friction pulley 92.

When the winding of a spool is completed, the friction may be released by slightly raising the lever 95 and the pawl 88 (Flgs. 11 and-l2) will be disconnected by its own weight when raised by slight pressure upon the foot piece 91. The pressure roll can then be swung upward in its bearings on the segment gears and 66, after which the full spool may be removed, an empty spool inserted, the yarn being secured therein, and being thereafter severed from the full spool. The end of the full s 001 is then rested upon the projection 126 *ig. 5) while the locking wire is withdrawn by the traveler 124 and parts associated therewith, which are thrown into operation by means of the control lever 151 and block 152. These parts may also be placed in operation by raisin the weighted end of the releasing bell cran r.

After the wire is withdrawn, the carriage into position on the new spool S, the latch 88 is caused to engage the shaft 75 as shown in Fig. 10, the lever 95 being slightly raised 'to permit the pressure roll to settle firmly in place, and the machine is then ready for winding the new spool.

Having thus described my invention and the details of construction thereof, it will be evident that many changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of my invention as set forth in the claims, and I do not wish to be otherwise limited to the details herein disclosed, but what I claim is 1.
