AUTOMATIC WINDING MACHINE.

Application filed August 21, 1924. Serial No. 733,412.

To all LO/2017b it may concern:

Be it known that we JEAN Josnrrrs, a citizen of the United States, residing at Philadelphia county of Philadelphia, State of Pennsylvania, and DAVID THEODORE BERLIZ- i-inrirnn, a citizen of the United States, residing at Philadelphia, county of Philadelphia, State of Pennsylvania, have jointly invented a new and useful Automatic Winding Machine, of which the following is a specification.

In our prior Patents No. 1,298,221, dated March 25, 1919, and No. 1 -137 976 dated Dec. 5, 1922, we have disclosed an automatic winding machine wherein a plurality of quills, cops, bobbins or spools are wound with thread drawn directly from the skeins without rendering it necessary to first wind the thread upon spools; and wherein if in the course of winding any particular quill or the like the feed of the yarn should be interfered with, certain mechanism which effect the winding operation will automatically be stopped.

The automatic winding machine as embodied in the present invention involves some of the generic principles of our prior patents aforesaid augmented in efliciency and commercial usefulness by reason of certain novel constructions, a synopsis of which follows:

The leading object of the present invention is to provide an arrangement,- connection and combination of parts for an automatic winding machine of the character disclosed in our said patents whereby a more efficient, accurate. positive and generally improved functioning of parts ensues to increase the commercial betterment thereof. A further ob ject of the present invention resides in the provision of details of construction arranged to attain the results sought by said leading object among which may be mentioned the following:

A novel arrangement of drive mechanism including a pair of eccentrically operating gear wheels for causing the main drive shaft to function at variable speeds, whereby a quill or the like is caused to revolve slowly as thread is fed along the major portion of.

its length and is caused to revolve more rapidly as the thread is fed to the tapering end portion thereof. Such variable speeds as i pa ted t t will at the like res lt i t e swift acquiring uniform speed in its revoluvariable speed to the machine carriage in its reciprocating movement.

(0X) A novel arrangement of coupling for the main driving shaft and for the carrierbox lead-screw whereby through the instrumentality of universal connections perfect alignment of coupled parts is attained.

(c) A novel arrangement of carrier-box including automatic, quickacting, stop mechanism operable (1) in conjunction with machine kick-off whereby a quill or the like is prevented from rotating and the carrierbox is locked against longitudinal movement, and (2) in conjunction with an automatic swift stop, whereby in the event of thread tangling, the carrier feed, quill and thread feed automatically cease to function until manually re-set by the operator.

(f) A novel arrangement of tensioning for thread as fed to a quill or the like including a fixed incline positioned parallel with the longitudinal axis of a quill whereby as the thread is fed to the quill. the thread guide moves along said incline to equalize the tension of the thread upon the quill.

(g) A novel arrangement of spindle parts including a floating drive 'upon a quill spindle whereby a pulley becomes self-seating when advanced to a spindle operating wheel.

(h) A novel arrangement of quill automatic stop for preventing quill rotation upon completion of a winding operation, the stop mechanism being capable of being adjusted to stop a quill independently of another quill or stop all quills or spindles at the same time.

The invention consists of the novel construction hereinafter described and finally claimed.

' The nature characteristic features and scope of the invention willbe more fully understood from the following description taken in connection with the accompanying drawings forming part hereof, and in which:

For the purpose of illustrating our invention we have shown in the accompanying drawings one form thereof which is at present preferred by us, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which our invention consists can be variously arranged and organized and that our invention is not limited to the precise arrangement and organization of the instrumentalities as herein shown and described.

Referring now to the drawings in detail. the numeral 1 designates a vertical standard, of which two are employed, one at each end of the machine. The numeral 2 designates a horizontal bed plate supported upon the standards 1. The machine may be of any desired length so that any required number of quills, cops, bobbins or spools may be operatively arranged thereon. The machine is constructed for duplicate sets of quills, cops, bobbins or spools, one setupon each side of the machine throughout its extent. Arranged at one end of the machine is a head 3 supported upon a stand 4 in which head is arranged drive mechanism. a description of which will now be given. Mounted in the head 3 is a shaft 5 rotatable upon which is a clutch drum 6. motion being imparted thereto through a belt 7 passing around a pulley fixed to shaft 8. This shaft 8 is driven by means of an electric motor 9 connected to said shaft 8 by means of a belt 10. These parts are best seen in Figs. 2 and 3 and a duplicate arrangement of parts is to be found upon each side of the machine although a description of one will sufiiee. Cooperatively arranged with respect to clutch band 11 is a clutch 6 which rotates a gear wheel 12 which, in the operative position of the clutch 6, is in mesh with a gear wheel 13 fixed to cross shaft 14;. Fixed to cross shaft 1 1 is one of a pair of novel gear wheels eccentrically arranged for imparting a variable speed to the drive shaft which revolves the quills, cops, bobbins, or spools. The numeral 15 designates the eccentric gear wheel upon cross shaft 1 1, which gear wheel is in mesh with the other eccentric gear wheel 16 which is mounted upon the clutch (i. Eccentric gear wheel 16 has formed integral therewith, a bevel gear wheel 17. which is in mesh with a similar gear wheel 18, mounted upon a longitudinal stud shaft 19 coupled, in a manner to be presently described, with the longitudinal main drive shaft 20 which revolves the quills, cops. bobbins or spools. Also located upon cross shaft 1-1 is a gear wheel 21 meshing with a gear wheel upon a cross shaft 23 located in a. plane below that of shaft 14. Fixed upon shaft 23 is a box cam 2%. best seen in Fig. 3, for positively driving the machine 'arriage through the instrulncntality of a vertically disposed lever 25 and its adjuncts Which lever is pivoted as at 26 to a bracket 27 bolted between the frame 1 and stand t. The lever 25 is operated by means of a connection comprised of a bell-crank lever, fulcrumed as at 29, one arm 28 of which en= gages within the cam groove of the box cam and the opposite arm of which is adjustably connected to the lever 25 by means llii of a link the length of which may be increased or diminished to regulatecarriage the quills, cops, bobbins or spool, use is made of step-up gears located in the head 3 and which step-up gears are supplemental to a ratchet movement also located in the head and fully shown and described in our said Patent #1331976. Briefly stated, the ratchet in question which is designated 34 in Figs. at and 6, is mounted upon a cross shaft and is operable through the instrumentality of a pawl 36 actuated by. an eccentric 3? upon shaft 14: through the medium of a vertically reciprocating connecting rod 38. Shaft in turn carries a bevel gear wheel 35) in mesh with a bevel gear wheel 40 upon a short shaft ll supported in head 3, see Fig. 5. Mounted upon shaft 41 is a gear wheel e2 adapted to be selectively caused to mesh with speed change or step-up gear wheels 48, 4%, 45, or tG through the instrumentality of a hand lever 47. The head 3, as shown in Fig. 3, is slotted at 48 to accommodate lever 457 and is provided with notched side walls as at 49 to cooperatively receive the lever at? when moved to the various positions necessary to attain meshing relation of the gears aforesaid. The stud shaft 50 upon which the gear wheels -13, t-l, l5. and ib are mounted is adapted to be coupled as l'iereina't'ter described with the lead screw 51 which imparts longitudinal movement to the thread carriers, either to accelerate or retard such movement in ae cordance with the thickness of thread emp l eyed.

Having described the various drive mechanisms as contained. within head 3, a description will now be given of a novel form of coupling employed in. aligning the stud shaft 19 with the quill, cop, bobbin or spool revolving shaft 20 and in aligning the stud shaft 50 with the lead-screw 51 which operates the thread carriers. Since the couplings, four in number, are duplicates of one another a description of one will suliice. The coupling is of the,.universal type, in that any inequalities in shaft alignment is corrected. Each coupling consists of a pair of sockets 52 each fitting over a shaft end. Each socket is provided with feet 53 'which project from a socket Between the feet of opposed sockets is arranged a relatively pliable or yielding disc 54 of rubber or the like, the feet of the respective sockets being bolted together to securely clamp the shaft ends together. Thus, since the disc 54 is relatively yielding, any error in shaft alignment is compensated for which is of vital importance in a machine of the character under consideration because of the nicety of adjustment and precision of part movements required in operating upon silk or other-thread.

Having traced and described the various operating means in the head 3, and the coupling and connection of said parts with the carriage, quill, spindle and lead-screw, these latter parts will now be referred to. In the connection, it may be stated that these elements, for the most part, are fully shown and described Patent #1,4t37,976, and need therefore be but generally referred to. Secured to bed plate 2 of the machine is abracket 55, of which there may be any number, for pivotally supporting as at 56, see Fig. 17, a quill spindle casing 57, rotatably mounted in which is a quill spindle 58 which detachably carries a quill 59 upon which thread is to be wound. The quill spindle 58 is driven from main driving shaft 20 by means of a drive wheel 60, having a convexed peripheral rim for frictionally engaging a pulley 61 located upon spindle 58. The pulley 61 has a co-ncave'd or recessed periphery so that the drive wheel may cooperate therewith in operative position of the quill. In the connection it is to be noted that the pulley 61, as the spindle moves to operative position around its pivot point, should seat upon the periphery of wheel 60 without binding. To compensate for this we have devised a novel end-slip movement for the floating pulley 61., see Fig. 18. The spindle 58 is made in two parts, the end 62 having a screw-threaded stem 63 which is received in a screw threaded aperture in the end of the spindle 58. The end 62 has a collar (Set and has also keyed relation with pulley (ll. Thus the pulley has limited endwisc floating movement between collar and shoulder 65 of spindle 58 so that when spii'idle and quill move to operative position as shown in Fig. 17, the pulley tilwill selfseat itself with respect to drive wheel till. Also carried by and fixed to bracket is an inclined track arranged in parallelism with the horizontal axis of spindle 58 and quill 59, see Fig. 1.7. This is so that thread may be properly guided from athread carrier to the quill for even. and uniform winding thereon, as will hereinafter be more particu larly referred to. The ca riage upon which the thread carriers are mounted, and which is operated by the lever 25, hereinbefore referred to, see Fig. 3, is designated 65 and is best seen in Fig. 3. The carriage 65 is mounted upon rollers 66 which track upon spaced rails 67 and is pivotally connected to lever 25, by means of rod 68,-for reciproin our aforesaid cation longitudinally before the quills, cops, bobbins or spools in the same manner as described in our aforesaid Patent #1, .t37,976.

A description of the thread carriers, of which there is one for every quill, cop, bobbin or spool, and which carriers have longitudinal movement independently of the carriage movement, will now be given. Primarily, a thread carrier is operable by means of lead screw 51 which derives its motion from the gears in the head of the machine as previously described. The thread carrier and its adjuncts are contained in a carrier box as it is sometimes called, which is designated 68, and is best seen in Figs. 11, 12, and 13. The parts as contained in said carrier box comprise an automatic, quick acting, stop mechanism as follows: (a) mechanism which works in conjunction with the machine kick-off whereby a quill, cop, bobbin or spool is stopped from rotation; and longitudinal movement of the carrier box is stopped. (6) Mechanism which also stops automatically the swift stop to prevent tangling or breaking of. thread.

Referring now to these parts in detail, thread 69 is'guided from a swift 70 in a vertical manner behind fingers 71 fixed to a pivoted and normally vertical arm 72. The thread keeps the arm 72 in the position shown in Fig. 11, but should the thread for any reason break, or the end of the thread appear, the arm 72 through the force of gravity moves inwardly about its pivot thus causing tappet arm 7% which is also fixed upon the same pivot rod 7 3 as arm 72 to trip arm 75 of detent 77, pivoted as at 76, to re lease horizontally movable, spring controlled plate 78. This plate 7 8 in turn moves to the right, in Figs. 11. and 12, the lever 79 which is pivoted as at 80, and which is provided with a lug 81. This lug normally retains elevated a triangular shaped member 82, pivoted at SS, and bearing upon a lever 85, pivoted at 86. As lug 81 withdraws from support of member 82 the latter moves around its pivot point 83 and thereby per mits arm 85 to be moved around its pivot 86 by spring 87. The result is that the split feed nuts 89, see Fig. t-l. are disengaged f om lead screw 51 whereby stoppage of a thread carrier-box is accomplished. The split feed nuts 89 are connected with respect to the free end of lever 85, by means of an adjustable rod 90 and a member 91; Simultaneously the quill, cop, bobbin or spool is stopped from rotation by the lifting of pulley 61 from contact with drive wheel 60, as shown at the left hand side ofFigs, 7 and 8. This is accomplished by the functioning of the following. parts. The free end .of arm 85 is provided with a lrnocl-rer finger 92, which (as connection 90 moves upwardly to stop the thread carrier.) moves to the left in Figs. 8 and 20 one end. of pivotal lever 93. This lever 93 has pivoted thereto a link 94, slotted at its free end to receive the pin 95 of a detent 96 pivoted upon rod 97, which latter is carried by a pivotal arm 98. As the link 94. is moved to the left in Fig. 20, the detent 96 is moved in the path or travel of rotary kickoff 99, fixed to the shaft 20 carrying wheel 60. As the wheel 60 rotates, a tooth of said ratchet 99 kicks to the left in Fig. 20, the detent 96 and rod 97. This rod 97 also is arranged in the slotted part of a pivoted and vertical trip arm 100, best seen in Fig. 19, the working end of which is provided with a tooth 101 normally engaging a notch 102 of a member 103 carrying vertical, spring actuated rod 10st. This rod is movable, when released, through a bracket 106 secured at to quill holder 57, see Fig. 17, so that when the part 107 of rod 104: abuts against part 108 of bracket 106, pulley 61 is raised free of wheel 60. Taking up now the automatic swift stop to prevent breaking of thread in the event of tangling thereof, and referring to Fig. 2, (right hand side) thread 69 is guided to thread carrier box 68, through an eye 110 upon a wire 111 secured to machine frame 1. In case of tang-ling of thread upon swift 70 the wire 111 is pulled inwardly and moves member 112 around its pivot 113, thus drawing downward by connection 11%, the lower arm 115 of a bell-crank lever, the upper arm 116 being connected as at 117 to the free end of a pivotal lever 118 carrying a socket 119 fitted to which is a wire having a bent-up end 120. With the movement of pivotal lever 118, arm 93, see Fig. 20, is caused to operate link 94 whereupon detent 96 is moved into the path of travel of rotary kick off 99 to stop the rotation of shaft 20 and there after a quill, or the like as is readily apparent. Thus as a swift 70 stops the above described parts coact to cause part 120 to impinge against the squared end 121 of pivotal lever 79, see Figure 2, and trip the parts shown in said figures as previously described with respect to thread carrier box stoppage, to cause the split feed nuts 89 to become disengaged from the lead screw 51. The various operated parts just described may be re-set manually by means of lever 122 which is operatively connected therewith. Upon completion of the travel of carrier 68 in a direction toward the right or. in other words, to the finishing operation ofwiiiding thread upon a quill, said carrier 68 moves to the right in Fig. 9, the upper end 123 of a trip lever which is pivoted as at 12%, whereupon the lower end 125 of said trip lever to raise the free end of wire 120 previously referred to and which is seen also in Fig. 8, to cause functioning of the kic -off parts previously described with reference to F1 20, and repetition of which is unnecessary.

To release carrier 68 after completion of its travel lever 126, see Figs. 9, 11 and 12, which is pivoted at 126 to carrier 68, is manually operated to abut against stop 127 in which position, through the instrumentality of various connecting parts braking device 127 is released from engagement with the upper of the split feed nuts 89. At such time as the feeding mechanism is disengaged with respect to carrier 68 it is desirable that the carrier be prevented from working too free- 1y. Referring now to Fig. 15, the carrier 68 is provided with an offset within which are arranged oppositely disposed, spring pressed, friction plungers 84 for impinging against guide rod 8%. The frictional contact of said spring pressed plungers may be increased or diminished by adjusting screws 86?. Referring again to Figs. 8, 11, 12, 13, and 19 and to the operation of setting pulley 61 in operation at the same time with carrier 68, it is to be noted that when hand lever 122 is moved to raised position said lever causes arm 130 (see Fig. 8) which is pivoted as at 131 to lever 122, to move upwardly and thereafter move crank 132 about its pivot point 133. This causes pin 134 upon crank 132 to move one end of previously described arm 85 upwardly around its pivot point 86 whereupon braking device 84- previously referred to is disengaged from the upper of the split feed nuts 89 with the result that the carrier 68 is in proper position for functioning with respect to a quill or the like. It is to be further noted that at the same time hand lever 122 has moved lever 135 (see Fi 8) around its pivot point 136 with respect to lever 122 with the result that bell crank lever 13?", the lower end of which moves in the slotted part 137 of lever 135, is caused to move about its pivot point 138, so that its upper arm 138 (see Fig. 19) causes detent 102 carried by part (kick-oil) to engage in notched part 102 of member 103 whereupon pulley 61 is placed in position for functioning at the same time as carrier 68. It, is to be further noted that when lever '85 is lowered to starting position, plunger 129, the face of which is bevelled as at 129, (see Fig. 13) is moved inwardly to pass lever 130 which is pivoted at 131, and that when starting lever 122 is raised plunger 129 is caused to raise lever 130 around its pivot 131 to reset the horizontal, spring scribed.

It will now be apparent that we have devised a novel and useful construction in an automatic winding machine, which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while we have, in the present instance, shown and described preferred embodiments thereof which will in practice give satisfactory and reliable pressed plate 78 previously deresults, it is to be understood that the same are susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

In a winding machine a quill, a carriage operable to reciprocate before said quill, a thread carrier box including a thread carrier upon said carriage for presenting thread to said quill, a main driving shaft, means including eccentric gear wheels for rotating said shaft at variable speeds during winding of thread upon said quill, whereby said quill is rotated at slow speed during presentation of thread to the high portion of the quill and is rotated at fast speed during presentation of thread to the low portion of the quill.

15. In a winding machine a swift, a quill, a carriage operable to reciprocate before said quill, a thread carrier box including a thread carrier upon said carriage for presenting thread to said quill, a main driving shaft, means including eccentric gear wheels for rotating said shaft whereby said swift is operated at uniform speed and said quill at variable speeds during winding of thread thereupon, whereby said quill is rotated at slow speed during presentation of thread to the high portion of the quill and is rotated at fast speed during presentation of thread to the low portion of the quill.

In testimony whereof we have hereunto signed our names.
