Application filed January 23, 1918. Serial No. 213,433.

certain Improvements Relating to an Unwinding Device, of which the following is a specification.

TlllS lnvention relates to improvements in and means for winding and reeling cotton or other yarn trom cops into hank, cheese,

bobbin, spool or other form, part of the invention being applicable to loom shuttles, the

object in the first place being to facilitate the process of readying and to prevent slattering of the cop noses during winding, reeling or weaving and thereby greatly reduce the quantity of breakages and also the amount of waste usualy made.

With reference to my invention I would say it hasbeen found that in winding yarn from mule or twiner cops, a great amount of waste is caused by the coils of yarn in the cop at the interior and at the nose becoming damaged or entangled. In such cases the cop requires to be readied, a known process consisting in pulling away the entangled coils of yarn until the cop is straightened and the yarn is again free to uncoil in regular order. It is here that much waste occurs in the present system particularly if the operator is not very expert, and in many cases cops are entirely spoiled. Again in winding, reeling and weaving, many breakages of yarn are caused by the coils ofyarn at the cop nose becoming entangled through being dragged up the blade of the unwinding skewer or spindle or shuttle tongue by the coils of yarn from the lower portion of the cop chase. As already stated one of the objects of my invention is to avoid these defects, and to this end it comprises a removable conical or partly-conical and cylindrical cap fitting on the outer end of the spindle or skewer, its inner end projecting slightly within the cop nose, such cap being held securely on the spindle during working by friction or by a clip or clamp device cooperating with a suitable shape of spindle end.

My invention will be fully described with reference to the accompanying drawings in which,

F i gs. 7 and 8 represent sectional elevationsof other modified forms of cap. 1

The principal characteristic of my inven tion consists in employing with any ordinary winding skewer, shuttle tongue or spindle used for readying a readily-detachable cap Z) applied to its upper end, such cap being larger in diameter than the spindle and of a form which while enabling the yarn to be unwound from the cop. as shown in Fig. 3, will hold the coils at the cop nose 0 in posi tion to prevent their becoming entangled during readying. A preferable form of the cap is that of an inverted cone (Z or a partly conical and partly cylindrical construction as shown in Figs. 1 and 2, the lower part of the conical portion entering somewhat into the end of the cop nose. The cap may be held on the end of the spindle a by friction or by a clip or clamp device co6pcrating with a suitable shape of spindle end. The clip or clamp device may be adapted to be actuated from the outer end for gripping or releasing the spindle. This is the ar rangement shown in Figs. 1 and 2. me will be seen from these figures the spindle is re duced at e and withinthe conical and cylindrical portion oi'the cap is arranged a clip or clamp device comprising a central tube f having a bearing in a disk g, the tube being provided at its outer end with a knob /e.

and at its inner end with forked arms iv adapted to embrace the reduced end of the spindle. Between the shoulder j on the forked arms of the tube and the inner face oi the disk 9 is a spring X: which normallv forces the conical cap outwardly so locking the parts on the reduced end of the spindle. To remove the cap it is only necessary to grip its body and press inwardly to release the fork and then remove by gripping the parts between the end of the body and knob.

IVith the arrangements described readying is effected by passing the spindle through the cop, applying the cap and holding the lower end of the spindle in one hand while the other hand is used to manipulate the yarn, the cop nose being kept up to the In winding and reeling I provide a spindle or skewer a which will pass quite freely through the cop, in fact preferably quite loosely. The spindle may be of any suitable external shape and be of any required length. The lower portion of the spindle a, Fig. 3, may be passed into a spring clip bracket m formed with a hole a to allow the spindle to descend freely of its own weight or assisted by an attached weight 0 so as to always keep the cap at the upper end of the spindle in contact with the cop nose as unwinding proceeds. The clips may be conveniently secured to a rail or rodp running longitudinally of the winding or other machine, or the spindle 0r skewer may be passed through a hole in a bracket or in the ordinary skewer board so long as sufficient space is left on the underside to allow the spindle to descend. In this case a detachable weight at the lower end of the spindle requires to be employed. To prevent any possibility of the yarn becoming trapped between the upper end of the cop tube 9 and the lower end of the cap 0, when the cop is nearly exhausted I may employ a vertically adjustable stop bracket 7 below each spindle, or a continuous rail, against which the lower end of the spindle would rest before the cap made contact with the tube.

In Fig. 4: the spring clip bracket is provided with outwardly extending arms 8 to facilitate the passage of the spindle into the guide holes.

My invention is equally applicable as a cop skewer or shuttle tongue or spindle in loom shuttles, in which case, if desired, the cop nose may be kept in contact with the cap, as the unwinding of the yarn proceeds, by a suitable spring mechanism.

Figs. 5 and 6 show an embodiment of the invention in which a cap is located on the tongue or spindle or skewer of a loom shuttle, and in which a spring mechanism is utilized for forcing the cop toward the cap. In this case a slotted plate 7 is secured to the shuttle body and in its slot 8 a stud 9 may loosely slide. The stud is fixed to a bracket 10 forked at 11 to freely embrace the skewer or spindle A and offer no obstruction to its being turned about its pivot 12 for cop changing. The bracket passes behind the cop tube g while its side portion has secured to it one end of a flexible spring metal tape 13, the other end 14; of which is located in a metal case secured in the shuttle body. The tape and metal case are similar to a Chesterman tape measure the tape being springcontrolled in the same way. Then the cop is placed on the skewer the bracket 10 is brought to the position shown in Fig. 5, the tape being uncoiled against the action of the spring which is thus energized. As the yarn is woven off the cop is forced toward the cap I) by the action of the spring re-coiling the tape.

An arrangement of the character in which the cap is held on the spindle by friction alone is shown in Fig. 7 in which the cap Z) comprises a cone of boXwood or the like with a thin metal. tube 14 inserted in its bore 15 for a short distance. The outer end of the tube projects beyond the apex of the cone in order that it may enter the first coils of yarn at the cop nose. The bore 15 is very slightly less than the end of the spindle or skewer a so that when the cap is placed on the latter the parts are held together by friction. The bore 15 is preferably slightly tapered.

In Fig. 6 is shown another simple modification of the cap which has a solid conical body 5 and a bore 15 to it the spindle a freely, the latter being grooved near the outer end at 16. The upper end of the cap may be recessed at 17 to receive a tempered steel ring 18 split transversely at one point so that when the cap is pushed on to the spindle the ring will open and clip the latter around the groove so holding the cap 100 firmly. Thering may be kept in position by a disk 19 fitting in a groove 20, the outer portion of the latter being formed by burring or spinning over the cone material somewhat asshown. On the other hand, the 105 cap may be made in two parts, removablysecured together by screw threads as at 21, the outer end of the upper part being in that case solid except for the central hole for the spindle.

It will be, obvious that many other forms of clip or clamp maybe employed to secure the cap removably to the spindle without departing from the characteristic feature of my invention.

What I claim and desire to secure by Letters Patent is 2- 1. In winding, reeling and readying spindles or skewers and shuttle tongues, a removable cap'for the outer end of such spin- 120 dle having its inner end adapted to extend slightly within the nose of a cop on the spindle and to be held on the spindle by friction in such a way that it can be readily removed when required.

2. In winding, reeling and readying spindles or skewers and shuttle tongues, the combination with a spindle, of a removable cap for the outer end of such spindle, having its inner end adapted to extend slightly within 130 the nose of a cop on the spindle, and a clip or clamp device for detachably securing the cap to the spindle end.

3. The combination with a spindle of the character described, of a cap comprising a body of tapering form adapted to be applied to the tip of the spindle and have its smaller end extend into the nose of a. cop on the spindle, and means for securing the cap to the spindle adapted to be released by pressure exerted at the enlarged outer end of the cap.

4. The combination with a spindle of the character described, of a cap comprising a body adapted to be applied to the tip of of the spindle, a plurality of clamping j aws.

within the cap for engaging the spindle, and means extending through the outer end of the cap for releasing said jaws.

The combination with a spindle of the character described of a cap comprising a body adapted to be applied to the tip or" the spindle so that its inner end will extend into the nose of a cop on the spindle, spring actuated jaws within the cap for holding itin position on the spindle, and means extend ing through the outer end of the cap for releasing said jaws to permit removal of the cap.

(3. The combination with a spindle of the character described, of a cap comprising a body adapted to be applied to the tip of the spindle, a stem extending outwardly through the head and provided at its end within the head with a plurality of jaws adapted to grip the spindle, and a spring acting to hold the jaws in engagement with the spindle, said jaws being released by pressure on the stem outside the cap.

7. The combination with a spindle of the character described, of a cap removably fitted to the spindle tip and having one end extending into the nose of a cop on the spindle, and means whereby the cop is maintained in such relation to the cap.

3. The combination with a spindle of the character described, of a tapering cap fitted to the spindle tip and having its smaller end within the nose of a cop on the spindle, and means for maintaining the cop in contact with said cap.

In testimony whereof I have hereunto set my hand in the presence of two witnesses.
