Application Octcberl,

14 Claims.

This invention relates to quilling machines and its object is to improve the mechanism of such machines whereby to render them more reliable and efficient in operation and capable of being operated with more facility and less skill on the part of the attendant and also capable of being adapted by simply effected changes for the winding of either quills or the like coresl having enlargements at their butts or cops of the like lacking such enlargements.

The invention consists in novel meansrfor es ,tablishing and disestablishingl a driving connection between'the driving means of the machine and the mechanism to be driven thereby; in novel means for maintaining such connection automatically when once established, the same being however adapted to cause release when required by the attendant; in a novel mounting of one of `the two means formed by the spindle and threadguiding means so that one is movable toward and from Ythe other; and in novel means whereby the machine is adapted for the winding of cops.

l is the frame, 2 one of a horizontal row of bearings therein for pulleys or drivers 3 driven by a belt 4 and 5 a horizontal rock-shaft extending at right angles to the bearings 2, so much `being according to the known construction.

Each spindle 6 (which may have the spindle proper 6a screwed or otherwise removably secured .,thereto) is coaxial with one of the pulleys and is journaled at its forward portion in the .frame 1931, Serial No. 569,202

and capable of reciprocation longitudinally. It is adapted to be disconnectively connected with its pulley by a clutch described thus: The pulley has a cup-extension 3a which forms itself one member of the clutch. The other clutch member comprises a sleeve structure itself comprising vouter and inner sleeve portions 7 and 8 forming between them a spring cavityr9; a split conical spring ring' 10 inset in a circumferential groove 11 in the sleevestructure and adapted when the 65 latter,l is forced telescopically into the pulley-cup 3a to establish a friction grip between them;`a thimble 12 to abut` the pulley at this time; and `a spring 13 housed in the cavity between the thimble and the forward or closed end of thecavity, the thimble being preferably splined to the sleeve structure at 14. The sleeve structuremay have a bearing collar 15 for the spindle, which: at t1'6 has a collar fixed thereto and formed with keys 17 to engage in a spline 18 ,ofjthe sleeves of the 715 sleeve structure. Thus, the pulley being in rotation, the thrustwise-movable clutch member may be moved oner way or the other to establish or disestablish a rotary driving connection,` between the pulley and spindle, such movement lbeing; in- S0 dependent of the spindle.y The opening movement of the movable clutch member may `be'limited by an arm 44 hereinafter referred to (Figs.'1 and l0) The movable clutch member is shifted back or forth from a .control rod 19 or controllerhaving 35 a fork 19a engaging between collars 20 and 20al on said member (the former of which may be of yielding material)Y and slidable in the frame and bearing 2 and projecting at the front, being normally urged forward bya spring 21 betweeny the 90 fork and bearing and being adapted to be moved forward or back by a hand-lever 22 fulcrumed in the frame and having fingers 22a `between which lies a stud 19h on the rod. The rodis held releasably back, holding the` clutch closed, by the following means (Figs. 5 and9) Affixedto it is a projection or arm 23 which by gravity, assisted by a spring-pressed arm 24 pivoted thereon and bearing against a rod 40 (to ybe described) is held normally depressed (the rodv 19 having some 100 slight rocking motionfor the purpose)- The end of the projection-occupies the crotch of an angle?- lever detent 25 movable in a `vertical Afront-to-- rear plane to limits aiorded by its SupDOrting bracket 26 in which Vone or the other arm of the ,1.05 detent is up. When the rod .19 is moved forward or backward the projection ,shifts this detenty one way or the other. When it is moved back,`to establish the clutch, arm 25a ofthe detentj is so fashioned that the projection (urged downward as described) forces the detent to the dotted line shown in Fig. 9, or where the fulcrum of the i detent is in the path of return movement of the projection with the controller (rod 40 being cut away at the top at 40a, Figs. 2 and 7, to permit the projection to assume this position) and the lever bears against a stop formed by the bracket 26; in this position of the parts, therefore, the

rod will be locked back, maintaining the clutch closed. The bracket is split at 26a, the portion above the split forming said stop, which is adjustable up and down by providing anadjusting screw 27 set in one and bearing against the other portion of the bracket as 'thus split and a clamping screw 28 connecting themfIn-this example the controller may be released by sufficient sudden downward pressure on the lever 22, taken with some rocking of the controller in its bearings, to jar the projection upward so that it then rocks the detent to permit return of the controller.

For reciprocation of the spindles rock shaft 5 has cranks 29 connected with the spindles thus (Figs,y 7 vand 8): Each such crank has pivoted thereto on an axis parallel with the rock shaft a lever 30 fulcrumed in an arm 31 pivoted to the yfran1e,`wherefore as the crank oscillatesthis lever willrbe oscillated thereby around such fulcrum. YThe spindle revolves in a bracket 32 kept from ro,- tating by having a fork receiving rod 19 ',(Fig. 7 andl confined to the spindle between two collars 33 thereon. The lever 30 and this bracket have --upright slots 34 facing each other (Figs. 1 and 9) and they receive rollers 35 on a link 36 pivotally connectedv with a lever 37 (Fig. 2) fulcrumed in the frame and itself connectedby a link 38 with an arm 39 fixed on the rod 19. When the rollers 35 coincide with the ful'crum of lever 30 (see Fig. 7) the crank 29 will obviously impart no motionto the spindle; but when rod 119 is repressed to close Ation will. be imparted tothe spindle.

the spindlerotating clutch and the link conse- `quently elevates tthe rollers in slots 34 reciproca- Thus to start or stop a spindle (as to both rotation or reciprocation) requires simply movement'of rod 19 .backward or forward.

A rod 40 is journaled to oscillate in frame 1 and it has alixedthereto bearing brackets 41 and 42, 'forming therewith a carrier which is` urged clockwise in Fig. 4 by a spring 43 (Fig. 2)v coiled about j 1 and 4) ranged the thread-guiding rneansk comprising the the rod and engaged with frame 1 and an arm 44 secured on the rod, this movement of said carrier being limited by contact of an adjusting screw 45 in bracket 41' with a stop 46 on the frame (Figs.

In the brackets of said carrier is arthread-guide rod 47, having the thread-guide 48, and the revoluble threaded thread-guide-advancing rod 49 havingthe friction wheel 50 to bear on the package being formed on the spindle, the two rods being connected to move together longitudinally by fork 51 on the rod 47 engaged between collars 52 on therod 49; to permit the rods to rock with the carrier they project through slots 47aj 49a in the front of the frame l. A collar 53kad- ,instable on rod 49 limits the forward motion of ter but the operator may push back the rods 49-47, the inclined faces of the nut then sliding over the thread of rod 49. A cylindrical housing 57 encloses the forwardly projecting part of the spindle and the quill a, projecting from the front face of the frame and protecting the package being wound thereon from lubricant thrown off by the other parts; its upper portion forms a hinged cover which may be raised when dofling.

The operation may be briefly stated as follows: The pulley 3 and rock-shaft 5 are constantly driven.- Having placed a quill a on the spindle with the thread-guiding means in its back position and attached the thread to be wound to the quill the lever 22 is operated to close the clutch and thus start the spindle rotating and shift link 36 to the position where crank 29 will be effective, as described, to reciprocate the spindle. Each time the friction wheel is engaged by the conical portion of the quill (or later the resulting cone of the windings) as the spindle reciprocates rod 49 is rotated somewhat and by its engagement with nut 55 causes the thread-guiding means to advance. The carrier of said means yields rotatively around the axis of rod 40 on each impact of the windings with the friction wheel, to permit the latter to run up the cone. When the winding of any unit is completed the collar 53 encounters the arm 25o of detent 25, which trips the detent so that rod 19 is free to' advance to ldisestablish the clutch and return rollers 35 to the position coaxial with the fulcrum of lever 30, or

neutral, wherefore the motion (both rotary and reciprocatory) of the spindle ceases.

In respect to the means for causing traverse of the yarn, it is apparent that it is not material which of Y the two elements constituted rby the spindle and a part such as rod 40 is reciprocated, though in this example it is the spindle; nor is it material to which of the two elements the lever is pivoted; nor that the actuator (29) move back and forth by oscillating rather than by some other movement generally lengthwise of the axis of said spindle. The use of a lever, as 30, in this connection makes it impossible for the attendant to establish the reciprocated means reciprocating its fall stroke suddenly, or without gradually increasing the length of the stroke, so that undue strain on the thread being wound is at this time also impossible.

One important feature of the invention is that the thread-guiding means is supported by a carrier rockable in the supporting structure around an axis substantially parallel with that of the spindle. Heretofore (see Adsit Patent No. 1,178,045) movability of the thread-guiding means toward and from the spindle was obtained by supporting it so as to be oscillatory around an axis transverse to it and adjacent its rear end, which made its action uncertain and irregular and incapable of producing the nicely formed packages possible by the present construction.

When a quill or the like having a pronounced cone or enlargement at its butt is used such cone affords an abutment for impact of the friction wheel with the cone at the start of the winding.

But when a paper cop or the like, as b, Fig. 15, is

used which lacks such pronounced enlargement it is necessary, as is known, to build up a synthetic, as it were, enlargement of windings on the cop, and this, which is to formv the heelA of the package, should have a nicely defined conical rear face. In Figs. 12 to 1'4 mechanism for performing the winding of a cop is shown'.

jce

It will be understood that in thisl example the spindle and the ineens for eiecting and con trolling its two motions (rotary and reciproca tory) are the same as above described; lilrewise is the thread-guiding means comprising the men tioned carrier and thread-guide and thread-guido advancing rods, excepting that in this form a spring 58 urges said means laterally away from the spindle, or anticlockwise as viewed Vfrom the front. Rod li0 of said means has aiixed thereto a bracket 59 in which is fulcrumed oe-- tween its ends an upright lever 60 confined to `move in aplane parallel with the rod. This lever is normally urged by a spring 6l clockwise in Fig. 12 and its lower end has a roller 62 bearing against an oblique surface 63a of a xed guide 53, its up per end having a stud 64 inthe path ofthe collar 52 already mentioned; Surface 63a is pitched to the angle which it is desired the butt surface of the wound mass `should present. 64u. is; a stud on the lever which may abut an adiustable stop 65 on rod 40. The carriers proximity to thespin dle therefore depends on the point in surface 63a at which the lever 60 (towit, its roller) engages said surface.

When the control rod -is repressed to start the winding operation collar 52 tilts the lever S0 anti clockwise and as its roller travels Valong' surface 63d the thread guiding means is urged, against the tension of spring 58, toward the cop b on the spindle. When the spindle is now driven and as soon as some windings formen the cop the thread guide-advancing rod (by contact of vthe friction wheel with these windings incident to the recipro cation of the cop with the spindle) undergoes intermittent rotation. yThis advances the thread guiding means, with consequent clockwisev move ment of the lever under tension of its spring so that it runs, as it were, down the incline 63a and so allows the thread-guiding means to recede fromthe cop. This process'goes on gradually, thevwindings forming in stepped layers on the cop which develop a rearward taper having more or less the same angularity as surface 63a. in this way the butt or heel of the package is formed. This action continues as -long as the levers motion under tension of its spring 61 is not checked. VIt may be checked at any point (thus to determine the diameter of the cone of the package heel or butt and hence 'of the cylindrical part of the package) according to the position of stop .65. Upon the rearward cone of the bein, developed in this way the operation to ni'sh the package is the same as that heretofore' described, or as in winding a quill. When the operation of winding is completed and a fresh cop to be wound the attendant represses the thread-guiding means lto reset lever 6i) in thev position where it engages the outer end portion of surface 63a and said means proximatesthe cop.

To change the machine to adapt it to winding cops instead of quills requires only to remove the parts 43 and 54 and add the `parts 58 to 65.

While the lever and surface 63a are utilizeL in the present instance in actually controlling motion of one of twoV means (spindle and thread guiding means) directly concerned in the wind ing transversely of the winding axis during the winding and also on resetting for starting the winding anew it will be seen that essentially these instrumentalities together determine the distance apart which said means may assume according to the position the lever is turned aro-und its fulcrum.
