Beirne Gordon, Jr., Utica, N. 'Y., aSsignorQto Skenandoa Rayon Corporation, Utica, N. Y., a corporation of New York V I Application December 21, 192s '2 Serial ,No. 327,611 Claims. (Cl. 242-433) This invention relates to a new and improved winding machine more especially designed for winding yarn, thread and the like, such as silk, wool, cotton, rayon, etc.

The usual method of winding such material'is to provide a bobbin mounted on a rotating spinthe speed of the traverse is to a certain extent limited, due to the necessity of. successively rais-' ing or elevating the traversingplane, and an ob-.

ject of this invention is to provide a construction of winding machine which can be run at-almost any desired speed, due to the fact that the tra- 2 verse guide always remains in one plane.

sides in the fact that the traverse plane of the thread-guide is not continuous and the operation is not positive and smooth, and another object of this invention is the provision of a construction in which theelement which receives the material being wound, as for instance a bobbin, is caused to move continuously, positively and uniformly, with respect to the unchanged traversing plane of the thread-guide,

Another advantage of this invention resides in the fact that the angle of the thread from its usual guide to the traverse guide remains within the limits of the traverse, whereas this angle is constantly changing in present types of machines wherein the traverse guide is being successively raised to accomplish the building of the package being wound.

This change of angle in' present machines causes a constant change in tension on the thread to its disadvantage, particularly in the winding of material, such as rayon. Furthermore, such a change in tension results in a package of uneven density. Other objects and advantages relate to the size, shape and relation of the parts, all as will more fully appear in the following description taken in connection with the accompanying drawings,

in which:

Figure 1 is a vertical section through my device.

Figure 2 is a section on line 2-2 of Figure 1.

Figure 3 is a section on line 3-3, Figure 1. Figure 4 is a section showing certain parts in' elevation on line 4-4, Figure 1. Figure 5 is a section on line 55 of Figure 1.

In the drawings I show a base --1 having A further difliculty with present machines resecured thereon an upwardly extending frame -2 having opposed bearing-supports -3-- and -4. 0n the upper surface of bearing- The inner end of. shafts8- carries a beveled gear 13 secured thereto by a set screw 14-.

A worm--15 is securedto-shaft -8- between bearings 9-- and 10-. a

' A second shaft 16.is' journaled in a bear- --17- in bearing-support --3 and carries on its inner end a beveled gear --18 secured thereto by a set screw --19. The outer end of shaft -16- is provided with a, crank-arm 20- secured thereto by a set screw 21--. A link --22 has one end *pivotally mounted on crank-arm 20 by' means of pivot pin .--23-- and has its'other end pivotally mounted-in a yoke 24- secured to the lower; end-of a reciprocating shaft --25- jou'rnaled in thread guidesupport -5-. The upper end. of shaft-'5 has secured thereto a thread-guide --2'7 by means of a set screw 26-.

A bobbin-shaft 28- has its lower end journaled in the base of bearing-support -2-, preferably by means of a ball bearing -29. A ball bearing 30-- positioned in the upper end of bearing support -2-- acts as an intermediate bearing for shaft 28.

A beveled gear -31- is keyed to shaft 28- beneath bearing --30-- and is continuously in mesh with gears --13- and 18-. The upper end -32 of shaft 28 is square in crosssection, and extends upwardly through an aperture 33- in bearing-support 34-. Aperture -33- is sufficiently large in diameter to permit the free rotation therein of end 32-- of shaft 28.

Bearing support -34-- is secured in the main bobbin support --35 by a set-screw -36-. A 105 ball bearing --37 is held in position on the upper end of bearing support -84 by a bearing-cap --38-.

A bobbin-spindle -39 carries a downwardly extending shank --40 journaled in bearing e -3'land is provided with a curved spring --4lhaving its opposite ends extending outwardly through slots in bobbin-spindle --39. Bobbin-spindle 39- is provided with a central aperture square in cross-section, and of a size to receive the upper end 32 .of shaft 28 which is slidably, but not rotatably mounted therein.

The outer end of main bobbin support --35-- is slidably mounted on guides 42- and 43- carried on the upper end of frame -7-. A pulley 44 is rotatably mounted on the upper end of frame ---7- above main bobbin-support 35. A counterweight 45 is secured to one end of a cable 46- which passes over pulley l4- and has its other end secured to main bobbin support 35- to support the weight of the latter.

A threaded shaft -47 has its lower end journaled in a bracket 48 secured to frame -7--, and carries adjacent its lower end a worm gear 49- continuously in mesh with worm 4-15- on shaft -8-. Threaded shaft 47- extends upwardly through a split nut --50-- whichis held against rotation in a cage 51- carried on main bobbin support 35-.

The opposite halves 52- and SB-bf split nut 50 are provided respectively withppin's 54- and ---55. p and -55, are slidably mounted in a plate --56-- and the other ends of pins 54- and 55 extend outwardly into curved slots --57- and 58- in a pivoted plate 59-. .An operating handle 60 is attached to plate 59-. When plate 59 is pivoted

pins

54 and 55 will move in slots 57- and 58- and will be forced outwardly to disengage split nut 50- from threaded shaft 47- so that the main bobbin support 35 may be moved vertically independently of threaded shaft 47-.

Operation When it is desired to wind a cop on a bobbin, a bobbin 61 is placed in position onbobbin spindle '39-. I have shown as illustrative, a solid cylindrical bobbin, but obviously a bobbin of my desired form may be used and the bobbin may be perforated, if desired; Split nut --50- is then opened and main bobbin support 35- is moved vertically until the lower end of bobbin 61 is in line with thread guide 27- with shaft 25-- in the downward position. Split nut 50- is then closed into engagement with threaded'shaft 4'7--. The thread to be wound (none here being shown) is then passed through thread guide --27 and around the lower end of bobbin 61.

With the parts in this position, shaft 18- is caused-to revolve from any convenient source of power (none here being shown) with the result that through gears 13-- and 31- shaft 28-- will be made to revolve, and inasmuch as the upper end 32-- of shaft 28-- is in operative engagement with bobbin spindle --39--, the spindle 39- will also be caused to revolve, carrying with it bobbin 61, which is held securely on spindle 39- through the action of spring 41- which is in resilient engagement with the inner surface of bobbin 61. The rotation of bobbin 61 will cause the thread to be drawn through thread guide 27 and wound on bobbin 61.

The rotation of shaft 8-- will, through gears -13, 31- and 18 cause the rotation of shaft --16 with a resulting rotary movement of crank arm 20-. The.rotary movement of crank-arm 20- will through link 22- and 'ment of said guide. One of the ends of pins 5.4-

tation in cage 5lon main bobbin-support 35-, split nut -50- and main bobbin support 35- will be moved downwardly, carrying with them bobbin 61-. This downward movement of bobbin 61- past thread guide 2'7- will be continueduntil the upper end of bobbin 61- is in line with thread guide 27, when the latter is in the raised position. When this movement has beencompleted, the machine will be stopped so that the bobbin with the cop thereon maybe removed and a new one substituted for a repetition of the cop-winding operation.

In Figure 1 I ha veshown inheavy lines a thread-guide 2'7-- in the downposition, and

in dotted lines thread-guide 27-- in the raised position as illustrative of the traversing move- I have also shown in dotted lines the shape which the cop will have when it has been wound on bobbin -61, the cop being thicker at the central part than at the end because of the fact that the reciprocating movement of thread guide 27- combined with the continuing downward movement of bobbin 61- will progressively increase the number of overlapping threads from the lower end "of the bobbin,

cally with relation to each other, but it will be understood that a similar result will be obtained if the parts are arranged so that they will move horizontally or in any other direction, provided only that they move in substantially parallel relation.

It will also be understood that the mechanical means for obtaining my result may be variedto a considerable extent without departing from the spirit of my invention, and although I have shown and described a specific structure and form of parts thereof as an exemplification or embodiment of my invention, I do not desire to restrict myself to the exact size, shape, or relation of parts, as various changes may be made within the scope of the appended claims.
