1i Claims. ,(ill. MB- 27) This invention relates to winding machines for winding yarn, thread and other strand materials to produce cops, bobbins, pirns and similar forms 7 or packages wherein the yarn is laid in overlying courses on a conical chase with the cop assuming a generally cylindrical form with a tapered or pointed nose end from which the yarn delivers in unwinding.

In the following specification and claims the term cop is used in a general sense to designate a package of yarn of the type indicated and the term yarn is also employed in a broad sense as applying to all kinds of strand materials.

One object the invention is to provide a gang winding machine having a plurality. of winding units operated from a common driving means and adapted to be individually detached and removed from the machine for repair or replacement without other units.

disturbing the operation of the the accompanying drawings.

In the drawings:

Fig. 1 is a side elevation of one unit of the present improved winding machine shown with a portion of its frame or supporting casing in vertical 0 sectional view;

Fig. 2 is a plan view of the operating mechanism of the winding unit as constructed in accordance with the present invention;

Fig. 3 a development view of the grooved rim of the cam which operates with a variable traverse motion; and

Fig. 4 is a View of one form of cop or pirn produced on the machine.

Referring to the present drawings, the im- 0 proved winding mechanism is preferably constructed in the form of a unit which may be applied in multiple to a horizontal frame or casing to constitute a gang machine having any desired number of winding-spindles As illustrated in Fig. l of the drawings, the main frame of the machine comprises a suitable number of legs or standards 2 surmounted by a horizontal bed or casing 3 having longitudinally-extending siderails 4 in the shape of inverted troughs or boxlike casings.

The side-rails i are preferably made separate from each other and joined together at their opposite ends by means of crossmembers or end-plates 8 held by bolts 9. Each cross-member 8 has step portions 5 resting on. overhanging ledges 6 at the sides of the legs 2 and fastened thereto by means of bolts '7. A sheet-metal cover 13 rests on the crowned upper edges of the end-members 8 to enclose the space between the side-rails 4.

The operating-mechanism for each winding unit is assembled on a frame-member or bracket 10 which is attached to the inner lateral wall of the box-like. housing orside-rail 4 of the main frame 3 in such manner that any unit may be removed from the gang machine without disturbing its neighboring units or interfering with theoperation thereof. This provides for the removal of any one or more units for repair or replacement of their parts, and their reassembling on the main frame, without knocking down the whole machin to render the other units inoperative.

The bracket 10 has a vertical plate-portion 11 adapted to be bolted to the side of the lateral wall or" the hollow side-rail or casing 3 by means of bolts 12, see Fig. 2 of the drawings. Projecting laterally'from the plate 11 is a semi-cylindrical shell 14 provided with a hub 15 at its outer end, in which is held a ball-bearing for the windingspindle to be later described. The bracket 10 also embodies a similar hub 16 at the inner end of the shell 14 which is bored to receive a ball-bearing corresponding to that in the outer hub 15. As shown in Fig. 2, the ball-bearings may comprise outer annular races 17 held in the bores of the hubs 15 and 16 to co'clperate with inner races 18 secured fast on a horizontal shaft 20 extending axially of the hubs'l5 and 16. A series of balls 21 are disposed between the races 1'? and 1am provide anti-friction journals for the shaft 20;

The shaft 20 carries a flanged belt-pulley, 22 arranged between its journals and suitably keyed or secured rotatively to the shaft by means of a set-screw 23 illustrated in Fig. 2. The shaft 29 is provided'with an enlarged extension 24 at its outer end to which the winding-spindle, designated 25, is secured. As herein illustrated, the winding-spindle 25 is of tapered form to adapt it to receive the tapering quill or paper tube :L' on whichthe cop is wound, its rearward'end being formed with an enlarged shank 26 inserted in a bore 27 in the end of the shaft extension 24 and held in place by a threaded connection at 28.

Fast on the inner end of the shaft 20 is a pinion 30 which meshes with a larger spurgear 3'1 jour naled on a stud 32 carried at the end of a pivoted arm 33. The arm 83 is slotted to receive a bolt 34 screwed into a boss on the plate 11. Fast with the gear 31 is a pinion 35 arranged with its teeth meshing with a larger gear 36 which drives the traverse-cam 40 to be later described. The arm 33 is adjustable on the bolt 34 to provide for the substitution of different gears for the change gears 31, 35, whereby to alter the speed ratio between the winding-spindle and traverse-carn. The gear 36 has its hub 3'? connected with the hub 39 of the cam 40, both the gear and cam being journaleol on a headed stud-shaft 41 secured in a boss 42 on the plate 11 by meansbf a setscrew 43.

The shaft 20 of the winding unit m'ayb'edriveh from any suitable source of power through the means of a belt passing acrossthe periphery of the driving-pulley 22. Preferably the whole series of winding units is driven from one belt extending longitudinally through the hollow rail or housing4'in contact with the lower peripheries of the series of driving-pulleys 22. The drivingbelt,-.indicated at 48 in the drawings, may be arranged. in the manner as illustrated in U. S. Let: tersPatent No. 1,950,855, issued March 13, 1934 to Everett. G. Lewis. As therein shown the belt passes over idlers at either end of the machine andis. connected to a pulley on a line shaft or directly with an electrioniotor to furnish power to drive the. machine. Suitable means are provided for manipulating the belt to start and stop the machine, but these mechanisms are not herein shown and described as they are not related to the present invention.

The cam 40 is constructed with arms 44 radiatingffrom the hub 39 to support its generally cylindrical rim 45. The inner end or" the camhub 39. is reduced in diameter and inserted into the bore of the hub 37 of the gear 36 being keyed thereto with a set-screw 46 holding the parts rctatively connected.

The rim 45 of the cam 40 has a generally zigs zag shape as illustrated in the development View, Fig. 3, being formed with a slot or groove 47 following. the contour of the rim. Referring to Fig. 3,'WhlCh shows a development of the rim of the cam and its groove 47, the groove comprises six oppositely-inclined courses leads coextensive with the circumference of the cam. This gives the groove an undulatory course first in one dimotion and then in the opposite direction with the reversing portions of the groove located pointsat either side of a medial plane extending at-right-angles to the axis of the can In the diagram of Fig. 3 the dot-and-dasl'r iine Ca -CL intersects the center of the groove at the extreme ends of the courses at one side of the cam, while the three parallel dot-and-dash lines Z)b, cc and d-'d represent the opposite extremes of'throw of the cam in accordance with each course of its zigzag or undulating trackway.. It will be observed by reference to Fig. 3 that the distance e between the extremes of throw of the cam at the point designated is of the maximum, while at the next point the extent of the throw is slightly less as represented at f and,v again, for the last course the extent of throw is still. less as represented at g; Beyond this point the throw of the cam is increased again to the maximum as. represented ate.

.In, the. present form of construction, the arrangement of the thread-guida; its reciprocating traver e-bar ndthe means r. feeding the guide utwa y. a ne he w s-s n ur the longitudinal growth in the bobbin are constituted .of the sleeve 54 is fluted or knurled and driven through a bore in the plate 11 to fixedly secure it in connection therewith. An arm 55 formed integral with the bracket 10 extends rearwardly therefrom and is provided at its end with a bearing 56 in which is held a sleeve or bushing 57 for slidably supporting the traverse-bar section 51 at this end.

A slide or crosshead 65 is secured fast on the traverse-bar section 51 between the ends or" the sleeves or bushings 54 and 5'], a set-screw 61 passing through the side of the slide to clamp it to the bar as shown in Figs. 1 and The crosshead 55 is provided at its top with a forked extension 62 straddling a horizontal rod 63 held at one end in a-hole in the plate 11 and at its opposite end in an extension 64 of the outer bearing 56. The rod 63 is secured in place by a set-screw 65 shownin Fig. 1. The crosshead 60 carries a stud or pin; 65 .on which is 'journaled a bowl or roller 67 engaging the groove 47 the rim 45 of the cam 49. Through this latter connection the traversebar section 51 is reciprocated in its bearings to impart traversing motion to the thread-guide 50 carried on its outer extension 52.

The section 52 of the traverse-bar has its outer end slidable in an outboard hearing 69 supported from an outrigger or bracket '70 attached to the forward side of therail or casing 4. The bearing for the outer end of the traverse-bar section 52 is swiveled in the manner shown in Patent No. 945,885, above referred to, so that the inner end of the bar may swing inwardly toward the winding-spindle25 for a purpose as later explained; thepin -and-slot connect :1 between the two sections 51 and 52 providing for this displacement or the outer bar sectionf52. I

Y The thread guide 5e comprises a guide proper consisting in. a grooved porcelain member, designat'edflo, carried at the end of a bifurcated holder 71. The: arms of the thread-guide holder 71 are hingedly supported on the bar-section 52' by means ofbearings 72, and between the bearingsis a sleeve-nut '24 arranged to engage partial screwthreads on the side of the bar. The nut '74 car rie'sa disk-like contact-wheel 75 adapted to make peripheral contact with the layers of winding as they are disposed on the cop, whereby to turn the sleeve-nut 74to gradually advance the threadguide 50 outwardly along the axis of the windingspindle25.

- At the start of the winding the first layers or courses 0: turns of the yarn are laid directly on the surface of the cop-tube a: and the contactwheel '75 is displaced inwardly toward the spindle to eifeot the contact between its periphery and the winding This is accomplished by swinging the traverse-bar section 52 inwardly at an inclination to its. normal plane. The means for displacing. the'contact-wheel '75 in the manner noted consists in a former-arm '76 attachedto the outer end, of the traverse-bar section 51 and having. an. inclined cam-iace'lfl which engages an arm or finger. 78 on the thread guide holder '71. When the thread-guide is-slid back along the bar- "lating traversing motion of the thread-guide whereby the yarn y is. directed back and forth on the cop-tube :c to deposit it in a series of section 52, at the start of the winding, the finger '78will bear against the cam-face '77 of theformer 76 to swing the bar-section 52 inwardly to bring the periphery ofthe contact-wheel close to the surface of the cop-tube a: on which the windings are deposited. As the guide feeds outwardly along the traverse-bar section 52 a gradual recession of the contact-wheel 75 with respect to the winding-spindle 25 takes place as the finger '78 slides down the incline '77 on the former '76, this action being to accommodate the growth in the winding at the heel of the cop. The construction and method of the operation of this part of the present machine is described in detail and more fully explained in the prior patents above referred to.

The method of operation of the present improved winding mechanism is as next explained. A paper cop-tube or quill x is placed on the spindle 25 and the thread or yarn 1 led through the groove in the thread-guide 70 and its end secured to the spindle in any suitable manner. It will be understood that previous to starting the winding operation the thread-guide 50 is set back at the butt end of the spindle 25 by releasing the sleeve-nut '74 from the threads on the bar-section 52 to allow the guide-holder 71 to be slid along the bar.

Power is applied to drive the operating mechanism of the individual winding units by causing the belt 48 to be pressed against the drivingpulleys 22 in the manner as explained in the pending application for patent previously referred to As the pulley 22 is drivenfrom the belt 48 the shaft 20, is rotated thereby and, through the train of gearing 31, 35 and 36, the cam 40 is driven in a clockwise. direction. At each rotation of the cam 40 the roll 67 traverses its groove 4'? and the orosshead 60 is thereby reciprocated back and forth along its guide-rail or rod 63. The crosshead 60 is fast on the traverse-bar section 51 and thereby a reciprocating motion is transmitted to the latter and t0 the section 52 of the bar connected therewith. The reciprocation of the traverse-bar causes an oscilcrossing helices forming courses which build up the layers of the cop.

The cam 40 acts to impart motion to the thread-guide 50 with a variable extent of traverse. Referring to Fig. 3 of the drawings, as the cam turns in the direction indicated in this view the roller 67 on the crosshead 60 will travel from right to left in the groove 4'7. Assuming that the roll is at the right-hand end of the cam-groove 4.7, as shown in Fig. 3, the initial traverse of the guide 50 as the roll passes through the first inclined portion of the cam groove will be of maximum extent as indicated at e. The direction of traverse of the thread-guide is reversed as the roll 67 moves back in the oppositely inclined portion of the cam groove. 47 and at this point the extent of movement of the guide will be slightly less than during its initial traverse as indicated at in Fig. 3. As the direction of traverse is again reversed by the roll traveling in the next succeeding course of cam groove 47 the extent of traverse remains the same as indicated at 7, but at its next reversal the guide will have a still less extent of traverse as indicated at g in Fig. 3. Once again the guide is traversed to the same extent, but at its next reversal the length of travat e. i

As the winding proceeds the yarnis laid in series of courses in the manner as above explained and after. a sufficient number of turns have been deposited in one location to build up a predetermined thickness of. the layers of windings' the thread-guide is advanced outwardly along the winding-spindle. This progressive advance or feeding of the guide 50 axially of the winding-spindle is accomplished by the periph The present improved winding mechanism is compacted within a minimum space and assembled and mounted as a complete unit which may be removed from the gang machine for repair or replacementof its parts. without disturbing the other units. Each winding ,unit is detachable from the machine frame by merely removing the bolts 12 and withdrawing the bearing-casing 14 erse isincrased tothe maximum asindicated and the quill 54 from their openings in the hollow railA. For this purpose it is only necessary to disconnectthe section 52 of the traverse-bar from its opposite section 51 or, if preferred, to
