YARN-WINDING MACHINE.

Application filed January 17, 1923.

Be it known that I, Jacor. K. AL'rnMUs, a citizen of the United States. residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Yarn-Winding Machines, of which the following is a specification.

This invention relates to improvements in machines for winding yarn upon bobbins wherein are employed a yarn guide for delivering the yarn to the bobbin, means for raising and lowering the yarn guide for placing successive layers of yarn upon the bobbin, means for imparting gain movements to the yarn guide during the operations of raising and lowering the same to build the layers of yarn upon the bobbin, and means to arrest the gain movements of the yarn guide immediately upon the breakage or discontinuance of the yarn being delivered to the bobbin.

The objects of my invention are: first, to. provide a novel, sensitive and efiicient means which may be controlled automatically by very fine counts of yarn to arrest the gain movements of the yarn guide upon the breakage or discontinuance of the yarn being guided thereby to the bobbin; and, second, to provide novel and efiicient means for imparting the gain movements to the yarn guide which will have a wide range of adjustment for variations in the gain movements of the yarn guide and which will be capable of adjustment for minute,

variations in different gain movements for yarns of different sizes or counts, and. which may he quickly changed or adjusted to meet the requirements of a change of yarn.

With the foregoing and related objects in view, the invention consists in the novel construction, combination and arrangement of parts hereinafter described and claimed.

In the accompanying drawings, illustrating my invention,

Figure 1 is an end view of a yarn winding machine embodying my invention, part of the main frame of the machine bein 3 broken away.

dle, bobbin, yarn guide and adjuncts, show ing the mechanism for imparting the gain movements to the guide and for automatically stopping such movements.

Figure 5 is a sectional detail, in elevation of part of the mechanism shown in Fig. 4.

Referring to the drawings, the main frame of the machine includes end standards 2'and a horizontal bar 4- connecting them.

A bobbin receiving'and rotating spindle 5 is mounted to rotate in bearing 6 formed on a bracket '7 which is secured to and projects from the frame bar 4. The lower end portion of the spindle 5 is provided with a whirl disc 8 which rests normally on the leather covering 9 secured on the periphery of a driving wheel 10. The driving wheel 10 is carried by a horizontal shaft 11 which extends between and is journaled in bearings on the standard 52-. The shaft 11 constitutes the main'driving shaft of the machine and one end portion thereof extends outwardly from one of the standards 2 and it is provided with fast and loose pulleys 1.2 and 13, respectively, for the application thereto of a driving belt for actuating the machine.

The machine is provided with a vertical- 1y reciprocable builder frame or support 14 comprising a horizontal rail 15 and vertically arranged, parallel shafts or rods 16 connected to and extending downwardly from the respective end portions of the rail 15. The shafts 16 are vertically slid able in bearings 17 on the end standards 2, and their lower end portions are provided with brackets 18 carrying rollers 19 which rest upon cams 20 on a horizontal shaft 21. The shaft 21 extends between and is journaled in bearings on the end standards 2 and it is driven by a gear wheel 22 thereon in mesh with a pinion 23 on the main driving shaft 11. The cams 20 are shaped to effect the desired up and down movements of the builder frame or support 14 during the operation of the machine.

The general construction and operation of the parts thus far described are common and Well known in this art, and no detailed description or illustration thereof is deemed necessary herein.

The rail orsupport 15 carries a builder screw 24 which rises fixedly from a plate 25 screwed; thereon. Rotatably mounted on the screw 24 is a nut gear 26 having a downwardly extending sleeve 27 surrounding the screw 24 and having a plate or arm 28 engaged with the thread of the screw 24 to cause upward movement of the nut gear 26 when it is turned in the direction of the a "row in Fig. 4. One end of the plate 28 is pivoted, at 29, tothe gear 26, and the other end of the plate 28 is held normally in engagement with the screw 24 by a spring 30 connecting the plate 28 and gear 26. After moving the arm 28 from engagement with the screw 24 the nut gear 26 may be raised or lowered on the screw into any desired position thereon.

The nut gear 26 carries an arm 31 having a sleeve 32 which surrounds and is adapted to turn on the gear sleeve 27. The arm 31 is provided with a stud screw 33 on which is rotatably mounted a gear wheel 34 which is constantly in mesh with the nut gear 26 and which is adapted to be moved into and out of mesh witha pinion 35 when the arm 31 is turned on the gear sleeve 27 for purposes presently appearing.

Fulcrumed on the arm 31 is a thread guiding lever 36 comprising a. collar 37 and two arms 38 and 39 projecting therefrom. The collar 37 surrounds the screw 24'and the upper end portion of the sleeve 32 of the arm 31; and the free end of the arm 38 caries a head 40 having a thread receiving and guiding slot 41, as clearly shown inFigs. 4 and 5. The lever arm 39 extends into a slot in the upwardly extending flange on one end ofa lever 42 which is pivoted, at 43, on the arm 31. The other end of the lever 42 is fulcrumed against a post 44 which rises fixedly from the plate 25 on the builder rail 15 and between which and the pinion 35 the lever 42 extends.

The post 44 extends parallel to the'screw 24 and through an opening 45 in the arm 31 and permits the arm 31 and lever 42 to be raised and lowered with the nut gear 26 without otherwise changing their relation to the post 44.

The levers 36 and 42 and arm 31 are related to each other and to the post 44 and pinion 35 so that, when the head 40 is drawn toward the bobbin 46 on the spindie 5 by a strand of yarn 47 being fed to the bobbin, the tension of the yarn 47, even though it be extremely light will maintain the levers 36 and 42, arm 31 and gear wheel 34 in the positions shown by full lines in Fig. 4, with the gear wheel 34 in mesh with the pinion 35, causing the nut gear 26 to be turned by the gear 34 when it is turned by the pinion 35. Should the yarn 47 break or should its delivery to the head 46 be discontinued, stopping the pull of the yarn on the head 40 toward the bobbin 46, the

pinion 35 will be thereby permitted to move the levers 36 and 42, arm 31 and gear wheel 34 to the positions shown by dotand-dash lines in Fig. 4, and thereby stop the actuation of the nut gear 26 by the pinion 35 all for purposes hereinafter explained.

The pinion 35 is formed on the upper portion of a vertical shaft 48 which is arranged parallel to the builder screw 24 and post 44; and the pinion 35 is elongated and it extends the full distance of vertical travel of the gear wheel 34 with the nut gear 26 so that the gear wheel 34 may be moved into and out of mesh with the pinion in any position of the nut gear 26.

The vertical shaft 48 is fitted to turn in suitable bearings on a bracket 50 on the frame bar 4, and the lower end of the shaft 48 is provided with a bevel gear wheel 51 adapted to mesh with a similar wheel 52 on a horizontal shaft 53 which extends parallel to the main driving shaft 11 and which turns in suitable hearings on the main frame of the machine.

The shaft 53 is provided with a ratchet wheel 54 adapted tobe turned by two pawls 55 and 56 arranged rearwardaly and forwardly thereof, respectively. The rear ward pawl 55 is pivoted, at 57, to the lower end portion of an arm 53 which extends downwardly from a bracket 59 which is secured upon the builder rail or support 15. The arm 58 is secured to the bracket 59 by a set screw 60 which extends through a slot 61 in the arm 58 and permits the arm 58 and pawl 55 to be adjusted vertically relatively to the builder frame 14 and ratchet wheel 54. The forward pawl 56 is pivoted, at 62, on a collar or bracket 63 which is secured to one of the rods 16 of the builder frame 14 by screws 64 in a manner to be vertically adjustable thereon The pawl 55 is moved upwardly toward the ratchet wheel 54 by a counter weight 65 formed thereon; and the pawl 56 is moved downwardly toward the ratchet wheel 54 by gravity. The forward pawl 55 is adapted to engage and move the ratchet wheel 54 during each downward stroke of the builder frame 14, and the forward pawl 56 is adapted to engage and move the ratchet wheel 54 during each upward stroke of the builder frame 14.

The extent to which the pawl 55 moves the ratchet wheel 54, during each downward stroke of the builder frame 14, is governed by a stop screw 66 which is vertically adjustable in a lug 67 on the pawl carrying arm 58. During the downward movement of the builder frame 14 the lower end of the screw 66 engages the pawl 55 and moves it from operative engagement with the ratchet wheel 54 after the pawl has moved the ratchet wheel a predetermined distance governed by the position of adjustment of the screw 66. It will thus be understood that the screw 66 may be adjusted to cause the pawl 55 to turn the ratchet wheel 54 a very slight distance at each down stroke of the builder frame 14, or a more extended distance, as desired. A suitable set nut 68 is provided on the screw 66 to engage the lug 67 to look the screw 66 in different positions of adjustment.

The extent to which the pawl 56 moves the ratchet wheel 54, during each upward stroke of the builder frame 14, is governed by a vertically adjustable stop rod 69, the lower end portion of which extends through a lug 70 on the collar 63 to a position directly above an arm 71 on the pawl 56, and the upper end portion of which is screw-threaded and screwed into and through the bracket 59 on the rail 15. The upper end of the rod 69 is provided with a suitable head 72 by means of which it may be turned for vertical adjustment; and the threaded portion thereof is provided with a set nut 73 to engage the bracket 59 and lock the rod 69 in different positions of adjustment. During the upward movement of the builder frame 14, the lower end of the rod 69 engages the arm 71 of the pawl 56 and moves the pawl from operative engagement with the ratchet wheel 54 after the pawl has moved the ratchet wheel a predetermined distance governed by the position of adjustment of the rod 69. It will thus be understood that the rod 69 may be adjusted to cause the pawl 56 to turn the ratchet wheel 54 a very slight distance at each upward stroke of the builder frame, or a more extended distance, as desired.

In Fig. 3 the pawls 55 and 56 are shown by full lines in the positions they occupy at the lower end of the builder frame stroke, and by dot-anddash lines in the positions they occupy at the upper end of the builder frame stroke, the screw 66 and rod 69 being adjusted to permit the pawls to turn the ratchet wheel 54 to the maximum extent during each up and down stroke of the builder frame. By adjusting the screw 66 and rod 69 downwardly the extent of the movement of the ratchet wheel 54 by the pawls may be decreased to any desired extent.

The bracket 6 has a hand lever 74 fulcruined, at 75, thereon and provided with arms 76 and 77 which extend therefrom to positions beneath collars 78 and 79 carried by the whirl S and shaft 48, respectively. The arms 76 and 77 are provided with beveled portions 80 and 81 to engage the collars 7 8 and 79 and raise the whirl 8 and gear wheel 51 from operative engagement with the wheels and 52, respectively, when the hand lever 74 is moved for that purpose. The whirl S is slidably fitted to a square I moved by the lever 74.

The operation of the machine, briefly described, is as follows:

Power is applied to the main driving shaft 11 and the rotation thereof causes the wheel 10 to rotate the whirl 8 and spindle 5, and the cams to raise the builder frame 15 and permit it to descend by gravity.

During this operation, the yarn 47 is fed to the bobbin 46 upon the spindle 5 and wound thereon guided by the head on the yarn guiding lever 36; and, at each up and down stroke of the builder frame 14, the yarn guiding lever 36 is raised and lowered to cause the yarn to be wound in spiral-like superposed layers upon the bobbin 46.

As the yarn layers are thus wound upon the bobbin 46, the nut gear 26 is periodically moved upwardly on the screw 24 relatively to the builder frame 14 to impart the upward gain movements to the yarn guiding lever 36 relatively to its constant up and down movements by the builder frame 14, to build the successive layers of yarn upwardly upon each other and upon the bobbin 46.

The gain movements of the yarn guiding lever 36 are effected by the operation of one or both pawls and 56 on the ratchet wheel 54 and by the gearing between the ratchet wheel 54 and the nut gear 26 cansing the latter to be turned upon the screw 24, screw 66 and rod 69 to cause either or both pawls 55 and 56 to be actively engaged with the ratchet wheel 54 for the full length or fraction of the stroke of the builder frame 14. When the action of one pawl will suffice for the gain movement, the rearward pawl 55 may be moved downwardly on its pivot until its counter weight passes over the vertical centre of the pivot and rests against a projection on the arm 58 and holds the pawl 55 in an inoperative position.

When the forward pawl is set to effect the gain movement along for a low count of yarn and the rearward pawl 55 has been set to operate in conjunction with the rearward pawl in the same setting thereof to effect the gain movement for a higher count or coarser yarn, the change from one count to .the other may be quickly effected by swinging the pawl 55 into and out of operative relation to the ratchet wheel 54, and without changing the adjustments of the screw 66 and rod 69.

The yarn 47 passing through the head 40 tothe bobbin 46 maintains the levers 36 and 42, arm 31 and gear wheel 84 in the full line position shown in Fig. 4, during the winding operation: and should the yarn 47 break or run out, the pinion will immediately move the parts to the dot-and-dash line position shown in Fig. 4, and thereby break the gearing between the ratchet wheel 54 and nut gear 26 by moving the gear wheel 34 out of mesh with the pinion 35 and thus discontinue the gain movements imparted to the yarn guiding lever 36 without stopping its up and down movements by the builder frame 14, so that after the broken yarn has been repaired or a fresh strand of yarn has been run through the head 40 to the bobbin 46, the repaired or fresh strand will draw the yarn guiding arm 36 back to the full line position and thereby cause it to resume its gain movements at the same position with respect to the yarn layers on the bobbin 46 where the gain movements were discontinued.

lVhen it is desired for any reason to stop the rotation of the bobbin 46 and the gain movements of the yarn guiding lever 36, the same may be done by operating the hand lever 74 to *aise the whirl 8 and the gear wheel 51 from engagement with the wheels 10 and F2, respectively.

It will be understood that any desired number of spindles 5 with their yarn guiding arms 36 may be employed on the machine all operated and controlled in .com mon by the builder frame 14 and shafts ll, 21 and 53.
