v Specification of Letters Patent.

Application filed June 25, 1918. Serial No. 775,644.

To all whom it may concern:

Be it known that I, JAMES F. MACWIL- LIAM, a citizen of the United States, residing at Worcester, in the county of Worcester and Stateof Massachusetts, have invented a new and useful Cop-VVinder, of which the following is a specification.

This invention relates to a cop winder of the type in which the yarn is fed through a traversing guide to a conical cop former and in which the cop is wound upon a spindle rotating within the former. In machines of this type heretofore used it has been the common practice to mount the cop former rigidly upon the frame of the machine. This construction has been productive of more or less inconvenience and difliculty in removing the cops from the machine, and specially constructed spindles have been required in order to permit the dotting to be accomplished.

It is one of the objects of my invention to provide a machine in which the cop former is movably mounted so that it may readily be removed from operative position when it is desired to doff the spindle.

Another object of my invention is to provide a machine in which each spindle may be disconnected from the common driving means independently of the remaining spindles.

A still further object of my invention is to provide a machine having a movable cop former in which movement of the former from operative position will disconnect the spindle from the driving mechanism.

With these objects in view my invention contemplates the construction of a machine in which the cop former is pivotally mounted for vertical movement and is held in operative position by a manually movable supporting member. Each spindle is provided with a separate driving pulley and with clutch mechanism by which the pulley can be disconnected from the spindle at will. Connections are alsorprovided' between the movable cop former and one member of the clutch mechanism whereby the removal of the former from operative position will disconnect the driving mechanism;

My invention further consists in certain devices, combinations and arrangements of parts which will be" hereinafter described and more fully set forth in the appended claims.

A. preferred form of my invention is shown in the accompanying drawings, in

whichl- Figurel is a side elevation of one spindle of a cop winder togetherwith such other parts ofthe winder as are necessary for a clear understanding of my invention; Fig. 2

'is a longitudinal sectional view taken through the axis of the spindle bearings; Fig. 3 1s a detail Sectional view taken on the l1ne'33 of Fig. 1; Fig. 4 is a similar view taken on the line 4l of Fig. 1; and Fig. 5

is a detail section taken on the line 5-5 in Fig. 1 and showing the construction of the weight attaching plate.

In the machine embodying my invention the cop is formed upon a horizontal rotating spindle 10, the yarn 11 being conducted to the spindle in the usual manner through the guide 12 over a frictional guide wheel 13 mounted upon a portion 14 of the frame of the machine,- and thence through the traversing guide 15 to thecop former 16.

The guide 15 is mounted upon an arm 17* secured to a shaft 18 extending longitudinally of the machine. It will be understood that in machines of this type a plurality of spindles lO are provided, mounted in parallel relation throughout the length of the machine, and that a guide 15 and arm 17 is provided for each spindle. The shaft 18 to which the arms are secured extends the entire length of the machine and is provided with an arm 19 connected by a link 20 to a crank pin 21 mounted on a disk 22 and rotating with a shaft 23. The arm 19 may be provided with a slotted connection with the link '20 by which the traverse of the guide 15 may be adjusted.

The spindle 10 is mounted for both rotary and longitudinal movement in bearings 2 1, 25 and 26 as shown in Figs. 1 and 2. The

bearing 25 is provided with an adjustable cap which may be clamped tightly upon a sleeve 27 secured therein. This sleeveextends to theleft of the bearing 25 asshown in Fig. 2, and has looselymounted thereon a pulley 28 which may be driven in any suitablemanner, as by the belt 29. Rotatably mounted within the sleeve 27 -is a second sleeve or bushing; 30 provided with a square exterior portion 31, a reduced cylindrical portion 32, and a flange 33. The cylindrical portion32 rotates freely in the bearing 26 while the flange 33 and the left hand end of the square'portion 31 prevent I Patented July 28,

longitudinal movement of the bushingrelative to the bearing. The right hand endof the square portion 31 likewise serves as a shoulder to limit longitudinal movement of the pulley 28 on the sleeve 27. The bushing 30 is furthermore provided with a square hole extending axially therethrough, within which the squareportion 34 of the spindle The spindle,

10 is longitudinally movable. 10 is also provided with a reduced cylindrical portion 35 upon which is loosely mounted a sleeve 36 having an end flange or plate 37. This plate, as clearly shown in Fig. 5, is provided witha notch 38 and with a lateral projection to which is secured an eye 39. A weight 40 is secured to the eye 39 by a cord 41 passing over a guide wheel 41- and tendsvat all times to move the spindlelO yieldingly toward the right in Fig. 1. A rib 41 is secured to the frame of the machine and cooperates with the notch 38 to prevent rotation of the sleeve 36 with the spindle .10, the plate 37 sliding longitudinally along said rib as the spindle is moved to the left in the operation of the machine.

Mounted upon the square portion 31 of the bushing 30 is a clutch member 42 pro vided with a square hole and freely movable along the square surface of the bushing. The clutch member is provided with jaws 43 cooperating with jaws 44 on the driving pulley 28 to transmit power from the pulley to the spindle 10.

The cop former 16 previously referred to is shown in Figs. 1 and 4 as having a partial conical shape and as being open upon its upper side. The cop former is secured to an arm 45 pivotally mounted on the frame of the machine at 46 and having a depending arm47 to which is secured one end of a link 48.. The other end of the link 48 passes loosely through a hole 49 in an arm 50 (see Fig. 3) mounted upon a vertical shaft 51. This shaft has a bearing 52 in the frame of the machine and has secured to its upper end a yoke 53 provided with pins 54 extending into a circular groove 55 in the clutch member 42. The rod 48 is yieldingly connected to the arm 50 by a spring-56 as shown in Fig. .1., The arm '50 is held against a collar 57 by the pressure of the spring 56 and a secondcollar 58 is mounted upon the link 48 to receive the outward thrust of the spring 56.

The cop former 16 mounted upon the arm 45 is held in raisedvposition by a supporting member or brace 59 pivotally mounted upon a stud 60 secured to a bracket 61 mounted upon'the frameof the machine. The sup porting member 59 is provided .with a laterally offset weighted handle or operating arm 62, and the bracket 61 has a vertical extension .61 which overlies the arm 45 and limits upward movement thereof.

In the operation of my device the yarn is secured to the spindle when the latter is in extreme right hand position, asshown in Fig. 1, and the cop former is raised to the position alsoshown in that figure, when the .weighted handle 62 will automatically swing the supporting member 59 under the arm 45, and maintain the cop former in operative position. As the cop former is raised the arm 47 will move the link 48 to the right in Fig. 1, thus engaging the clutch member 42 iwith the driving pulley 28 and starting the rotation ofthe spindle l0. Shouldthe teeth be in direct alinement with the teeth 44 when the link 48-is moved to the right, the

injury to the operating parts and the clutch member 42 will be pressed yieldingly to :ward the pulley 28 until the cooperating iteeth have moved into proper relation with Ieach other. I

In my. device, as in other machines of this type, the yarn is moved backward and foriward by the guide within the length of the cop former 16 and as the cop is built up, the :conical end thereof bears against the former .and gradually pushes the spindle 10 toward ,the left, thereby raising the weight 40. \Vhen a sutlicient amount of yarn has been wound upon the spindle the operator raises the handle 62, thereby removing the supporting member 59 and allowing the cop former 16 to drop. This movement of the cop former is communicated through the link 48 vto the clutch member 42, moving the latter to the left, and thus disconnecting the driving mechanism. Furthermore, when the cop former 16 is removed from operative posiltlOl'l the weight 40 is free to act upon the spindle 10 and will return the same to initial position, the newly formed cop moving to the right of the cop former and being in con- :venient position for dofing.

If desired the spindle may. be started in irotation after dofiing, before the yarn is attached thereto, the open upper side of the ,cop former affording access to the spindle :so that the yarn may be attached while the spindle is in motion. This results in a material saving of time on some classes of work, the yarn being more readily secured to the spindle when in rotation.

It is evident that many changes and modificationscan be made in the construction of 1ny.invention by those skilled in the art without departing from the spirit thereof and Ido not wish to be limited to the pre- ;cise construction herein disclosed, but

Whatl do claimis 1.
