4 Claims.

This invention relates to what are known in the textile trade as ring spinning or twisting frames. As a rule, cotton spinning is performed on a frame in which there are what are known as 5 Rabbeth spindles which stand up vertically and revolve in suitable bearings, but do not move axially. Bobbins are fixed on them and revolve each bobbin on and with its spindle. Cooperating with these spindles and bobbins is a ring 10 rail carrying spinning rings, the ring rail being caused to move so that the center of each ring moves up and down along the axis of a spindle and of a bobbin.

When starting to build a bobbin, the ring rail 15 is dropped tothe lowest point opposite the head of the bobbin and if a warp wind is desired the rail with its rings is caused to move up and down the length desired thus building concentric cylinders of yarn.

20 If a filling wind is desired the ring rail is caused to traverse or reciprocate up and down gaining at each successive reciprocation so that a filling wind consisting of concentric cones instead of cylinders of yarn is formed.

25 On a cap spinning frame, such as used formerly for worsted, there are fixed guide rods which are not tapered but are cylindrical and which are improperly called spindles. These are fixed to what is known as a spindle rail and neither 30 move axially nor do they revolve. Each carries at the top, however, a cap around the lower rim of which the roving is delivered and spun on a bobbin which revolves partly inside and partly outside the cap.

35 Each bobbin is carried on a tube having a whirl, the carrier and bobbin being caused to revolve on theguide rod or spindle and also caused to traverse or reciprocate starting with the head about opposite the bottom rim of the cap and moving down and then up for a warp wind or reciprocating or traversing downward gaining after each reciprocation if a filling wind is desired.

It has been proposed to move both the ring 45 and a movable spindle either at the same time in opposite directions or with different movements according to the result desired.

An application for patent on Reciprocating 50 bobbin ring frame to cause the ring rail to move in a direction at all times opposite to that of the bobbin has been filed by Walter Cox and became Patent No. 1,998,981, April 16, 1935, and it has been proposed to cause the ring rail to 55 traverse or reciprocate progressively upward while a revolving spindle is caused to move steadily downward without reciprocating.

For a great many years, it was not believed that worsted yarn could either be spun on a spinning frame or twisted'on a twisting frame by the use of rings and travellers, but now ring frames are used to some extent.

One advantage of the cap frame was that the distance from the edge of the cap to the pot eye and the delivery rolls was constant and the conditions between those points, therefore always the same.

The serious objection, however, was the fact that the length of the yarn package was limited by the length of the cap and its diameter by the diameter of the cap.

It has also been believed that worsted should be spun and twisted on a bobbin having a cylindrical barrel and a head which was at right angles to the barrel and that the space between them should be filled by the use of a scaife or other similar builder motion which would start with a short traverse the length of which would gradually increase caused by the dropping of the bobbin, until the desired maximum was reached after which the bobbin would traverse progressively downward thus building successive cones in a well known manner provided a filling wind was desired.

The tendency among spinners and twisters of late years is to use the filling wind to the exclusion of the warp wind because each concentric cone appears at the surface and if there is any flaw in the yarn, it can be readily detected while with the warp wind, nothing but the outside layer shows and there may be many defects on the inside layers.

In what has been known and is known as the cotton ring frame, the bobbin revolves, but does not move axially, but the ring starts near the 40 head of the bobbin and reciprocates progressively upward. This means that, as each layer is built, the distance from the delivery rolls or guide eye through the traveller to the bobbin barrel or to the outside of the yarn package repeatedly varies and the tension likewise varies.

It is well known among spinners that on this type of frame only small packages can be built because, on account of the change in tension, the roving breaks.

On the other hand, with the cap frame or where a stationary ring replaces the cap, and the bobbin reciprocates downward, while the distance from the traveller to the barrel or to the nose of each layer is greater than to the outside of the layer, the distance from the traveller to the guide eye and feed rolls doesnot vary.

Too many reciprocations of the ring rail, causing variations in the tension, is objectionable as are also reciprocations of too great length for the same reason.

In this device, the ring rail is caused to move steadily upward while at the same time the bobbin revolves and is caused by the usual scaife motion to reciprocate progressively downward on a fixed spindle. In the usual operation of the scaife motion, the bobbin startswith a very short reciprocation which gradually increases to the maximum, and this short reciprocation, when the frame starts, avoids the rapid changes in tension produced by certain other motions and there are, therefore, fewer breaks.

With this construction we maintain'the advantage of having the bobbin reciprocate progressively downward, preferably starting with the short reciprocation as in the cap frame, while maintaining substantially the advantage of the relatively stationary or fixed lower rim of the cap, or a ring, and also, by moving the ring,

-which amounts to a delivery point, gradually upward, a longer bobbin or yarn package can be wound and, at the same time, dofiing is made easier because at the top end of the yarn package the rings are in the extreme up position, thus allowing the bobbin with its yarn to be more readily doifed. This upward movement of the ring rail is so gradual and continuous or of the step by step type that the variation in the distance from the guide eye to the ring does not tend to stretch nor to break the roving.

We show different mechanism for producing the preferred motion which is to move the bobbin reciprocally and progressively downward and the ring steadily or step by step upward but there are other mechanisms which could be utilized for producing this result and other results which may be useful in some cases.

For instance, the scaife motion may be set for a constant reciprocation of the bobbin rail, each reciprocation being of the same length and in the same position, while the ring rail moves steadily upward thus building concentric or overlapping layers of yarn which are not precisely V of cone shape but produce a yarn package of well known or pointed at both ends.

It is well known that many breaks occur when starting the frame and that breaks occur in a ring frame when the ring changes its direction. With the combination of the scaife motion acting on the bobbin and a gradual upward movement, which is not reciprocal, for the ring, a much better action is obtained than where the ring itself reciprocates the full traverse progressively upward.

It is better to give the ring rail a very slow steady upward movement which is neither reciprocal nor intermittent so that there will be no tightening nor loosening of the yarn'or roving, because when the movement is intermittent or reciprocal, more breaks occur.

Some means must be provided for bringing back the ring rail and the bobbins to the starting position. Preferably this should be accomplished from one end of the frame by disconnecting thedrive mechanism and turning back all the parts, but this resetting can be accomplished in various ways asby turning the usual hand wheel thus raising the bobbin rail and then by other means causing the ring rail to drop to the starting point. With the preferred construction, while the bobbins reciprocate and may move progressively downward, the ring rail can be caused to move steadily upward without reciprocating, the ring rail can be fixed at any desired height, or the ring rail can be caused to reciprocate progres- 5 end from the front of a spinning frame embodying this invention.

In the drawings, F represents a fixed frame and 60 I 8 represents a fixed spindle rail or guide rod rail from which upwardly project a plurality of guide rods R, R each of substantially cylindrical form and of a well known type.

Slidable and revoluble on each rod R is a bobbin holder H each of which is provided with a whirl H driven by a band or belt 12 as from a drive roller I3. Each bobbin holder H carries a suitable bobbin B having a barrel I and head 2 of any well known type.

A represents a bobbin rail upon which each of the holders H rests and S represents a builder motion the one shown being of the well known scaife type. As shown, this includes a lifter bar 20 from which extend chains 2| over pulleys 22 each one connecting to the bottom of a lifter rod 23 which slides in suitable guides up and down. These lifter rods carry the bobbin rail A.

The lifter bar 20 is caused to move by what is known as the motion screw 24 which passes through the motion nut 25 carried at the end of I the long lever 26 which is pivoted at 27 to the frame.

The shank 28 of the motion screw has a lengthwise keyway 29 which engages a key 38 in a hub 3| which carries a gear 32 and a hand wheel 33, gear 32 being revolved usually by a connecting gear 34 driven by a drive gear 35.

36 is a lock of the usual construction which holds the gears 32 and 34 together during the usual operation of the frame. However, when it is desired to turn back the parts, lock 36 is disengaged and wheel 35 is pulled out, as shown by the dotted lines Fig. 1 thus allowing the motion screw to be turned back in the motion nut bringing the parts back to their original positions.

37 is the monkey adjustable on the long lever and 38 is the short lever with which itcooperates motion being given the short lever by the heart 39.

4B, 40 represent the lifter rods for the ring rail C carrying rings 4!, ll each having a traveller 42, these lifter rods passing through suitable guides so that they can move up and down carrying with them the ring rail C. On each rod 53 is an adjustable button 4 4, the position of which can be adjusted as by a set screw 45.

46, 46 represent suitable pivot supports each carried by a lower rail W and each pivotally supporting a lifting lever L of the bell crank type. This is shown as pivoted at 59 and with one arm 5! of the forked type which extends around a rod 4!! underneath the adjustable button 64, the other arm 52 being bent at 53 and extending down and in front of another adjustable button 54 on a flexible lifter cable T which is connected with the special mechanism U, all transmitting motion from the scaife motion S to the ring rail C with its rings.

This cable T extends along the front of .the

frame and, as shown, is connected by means of a spring 55 with the other end of the frame and is shown as being supported by suitable guides 56 so that at all times it will remain straight and taut. It extends around a pulley 51 and from there is wound upon a barrel tit of a sprocket 6! which is connected by a chain 62 with a small sprocket 63 carried by the hub of a large sprocket 64 from which extends a chain 65 to another sprocket 66 carried by the hub st of the hand wheel 33 for the motion screw.

It is obvious that the reciprocating movement I of the motion screw produced by the heart 39 -not reciprocally upward as the bobbins move reciprocally or progressively downward.

Adjustable member 54, shown as a collar, can be fixed in any position on the cable T, which we might call a pulling member, as by means of a set screw I54 and adjustable button 44 can be adjusted in any position on ring rail lifter rod 40 by means of set screw 45. The result of this is that by suitable adjustments the ring rail can be started in an upward movement, as shown diagrammatically in Fig. 11, from X to Y or this 5 action can be delayed until towards the end of the yarn package which is being built on the bobbin.

If the ring rail is to move steadily upward and the bobbin rail with bobbin and holder to move reciprocally or to traverse progressively downward starting at the same time, the diagram in Fig. 11 shows what happens. In other words, the ring rail starts going up from X to Y at the same time that the bobbin starts going down from X to Z.

Starting with the ring rail C carried by vertically slidable ring rail rods 48 and the bobbin rail A carried by vertically slidable bobbin rail rods 23, it. is possible and'sometimes desirable to provide several difierent movements respectively to adapt the frame for different types of stock.

The scaiie motion, shown at S, is what might be called a universal builder motion because by suitable adjustments a filling wind, a warp wind or any other well known wind can be produced on a bobbin. For a spool or warp wind, the monkey 37 can be dropped to its lowest limit and the connecting gear 34 can be removed whereby the motion screw 24 ceases to revolve but does reciprocate.

By a very slight change in the construction and by combining to some extent with the construction shown'in application on Reciprocating bobbin ring frame, Serial No. 425,867 filed February i, 1930 by Walter Cox, one of the applicants '1 for this Letters Patent, it is possible to change the relative motions of ring rail and bobbin rail if desired.

In Fig. 8 there is shown a pivot stand 45 carried by rail W with a vertical series of holes 79, 1B, the same as shown in Fig. 1. A pin 50 passed through any one of these holes and through a suitable hole such as 41 in the part I50 of lever L or a similar hole in a lever M serves as a vertically adjustable pivot for such a lifting lever.

In either case by removing pin 50, the lever such as L or M can be entirely removed and the ring rail 0 thereby adjusted at any desired height by loosening the set screw 45 and moving the button 44 down until it rests on rail W, when by tightening the set screw it holds the ring rail in any desired position as shown in Fig. 9.

If the reciprocal action of ring rail and bobbin rail is desired, a lever such as M pivoted at H! with an arm 13 extending under a button 4 adjustable by a set screw 15 on bobbin rail rod 23 and another arm H extending under the button 44 adjustable by a set screw 45 on ring rail rod 46 is used.

The adjustable member 54 on pulling member T is moved over to the right out of the way and the buttons 4 and 44 are so adjusted that the movements of the bobbin rail rod 23 caused by the builder motion S are transmitted to the ring rail by its rods 40 whereby a reciprocal movement in opposite directions is given the ring rail and the bobbin rail.

With this type of lever M, an additional arm 12 corresponding with arm 52 can be fixed to arm 13 in such position that it can be engaged by the 70 adjustable member 54, as shown in Fig. 4 and the button 4 can be moved up out of the way to the full line position shown in that View. With this type of three armed rocking lever and the means such as the pin 50 to pull it out of action, with-- out any other changes the bobbin rail and ring rail can be reciprocally moved, the ring rail can be fixed in any desired adjusted position or the bobbin rail can be caused to reciprocate or traverse progressively downward while the ring rail is caused to move steadily upward.

There are various other ways by which the reciprocating and downwardly progressive movement of the bobbin rail can be converted into a steadily upward movement of the ring rail.

As shown in Fig-J4 the lifting lever can be dispensed with and a flexible member such as a chain i6 can be passed over a pulley such as I1 one end being fastened to an adjustable member 54 and the other end to a bracket 18 attached to the bottom of a ring rail rod 49.

The horizontal movements of the pulling member T are, therefore, transformed into similar vertical movements of the ring rail and its rods.

Insteadof a continuous member like I6 and a single pulley H, as shown in Fig. 15, a pulley lie with a hub I15 can be used.

A member H8 is attached to the rim IT! at one end and to 54 at the other end while the member I78 extends from the hub I15 down to a member like I8. With this arrangement, the movement of member T can be reduced or if the member IE6 is connected to the hub and I18 to the rail, the movement can be increased at will.

Another method of transmitting the motion is shown in Fig. 10 by a modified lever N pivoted at M9 to spindle rail I9 and having a short arm ill which extends under button 44 and a long arm H2 which extends down and in front of adjustable member 54.

In this way, the movement of member T is reduced so that the movement of the ring rail is' less.

As shown in Figs. 16 and 17 instead of using a sprocket such as 66 carried by the hub 3|, a gear 599 which is longer than gear 32 on hub SI also engages a gear I64, of much larger size, with a small hub gear I63 which engages another gear IGI with a small hub I61 on which is wound the end of pulling member T. The purpose of this long gear I99 is to permit the motion screw and its hand wheel 33 to be pulled out, as shown by the dotted lines in Fig. 16, for the purpose of winding up or moving up the bobbin rail when starting the winding of a new set of bobbins after domng.

In Figs. 18, 19 and 20 is shown still another method of transforming the downwardly progressive reciprocal motion of the bobbin rail into an upwardly steady movement of the ring rail.

To the lifter bar 29 is adjustably fastened a finger 99 in such position that when the frame is started it will just strike and move slightly an arm such as 9! fixed to a ratchet wheel 92 carried by a suitable shaft 93 in bearings 94 on the rail W such shaft also carrying a cam 95.

The two pawls 91a and 91 prevent the ratchet wheel 92' from turning back and these may be arranged in such positions that first one takes hold of a tooth and then the other, the space being such that the idle one will rest between two teeth on the wheel 92. The cam 95 engages a lever 99 which is pivoted at one end to any suitable part of the frame and at the other end connects with a flexible member I91 which runs up and over a horizontal shaft 98 which extends from one end of the frame to the other. The movement of cam 95 forces down the free end of lever 96 thereby turning the shaft 98 in the direction of the arrow. Another flexible member 99 is fastened to shaft 98 and extends in a direction opposite to I91 and is connected to a suitable bracket I99 similar to bracket I8 at the bottom of ring rail rod 40.

The result of this is that as the finger 99 moves 5 reciprocally and gradually gaining toward the left as the motion screw is unscrewed, ratchet 92 is slowly turned carrying with it cam 95 and depressing lever 96 thus turning shaft 98 and lifting the ring rail, through 99, which is shown 10 as fastened to a pulley I99 and passing over loose pulley 202. Set screws 2III and 293 permit the adjustment of I98 and I99.

The holes I96 in lever 96 permit a different adjustment of flexible member I91 whereby a 15 greater or less turning movement can be given shaft 98. The holding pulley I98 can be moved along shaft 98 to accommodate I91.

' I93 is a resetting handle to be used when returning the ring rail to its starting point by 20 turning the cam 95 so that its low part will engage lever 96 thus permitting the weight of the ring rail and other parts to return them to the starting position. When resetting, the pawls 91, 9la are thrown out of engagement with the 25 ratchet 92, as shown in Fig. 18, the cam is turned as stated, the hand wheel 33 is pulled out disengaging gears 34 and 32 and the motion screw is turned in the usual way thereby lifting the bobbin rail with its bobbins to the starting posi- 30 tion.

It is obvious with this mechanism that if the pawls 9i and 9'Ia are thrown out, the ring rail can be retained in top adjusted position while the bobbin will travel reciprocally downward in 35 the usual manner.

The ring rail and all its operating parts can be held in the top or up position by pushing a pin II I] through holes III and H2 thus holding arm 9I out of contact with finger 99. 40

If pawls 9'! and 91a are thrown out and pin I I9 is not used, arm 9| will transmit to the ring rail from finger 90, the reciprocal progressive movement given rod 20 by the builder motion, but in theopposite direction. 45
