- Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Winding-Machines, of which'the following is a specification. I

and particularly to machines for winding taper-ended, or' ointed cops such as that shown and described in U. S. Patent No.

"94:0,489' granted to Simon W. Wardwell',

November 16th, 1909. In this style of machine the t-aper-of the nose of the cop is regulated by a former, so-called, which controls the position of the contactwheel for regulating the disposition of the layers of winding in building up .the heel of the cop.

The present invention consists particularly of improvements in the constructionand arrangement of .the former-devices whereby the former arm can be set to "be ad justable; or, whereby it can be locked against adjustment 'to prevent inexperienced operators from. making incorrect adjustments.

The invention is fully described in the following specification, illustrated by the i accompanying drawings, in which to; Fig. 2, a longitudinal elevation of the same, looking in the direction indicated by 35.

The main'elements of the machine are the same as those shown in'the patent above re ferred to. Y

Referring to Figs. 1 and 2, b is the winding spindle adaipted torotate in bearings in .the frame 0 of the machine and preferably tapered throughout its leng't-h extending outward from the frame to adapt it-jto receive the cop tube w, represented by dotdriven from' a rocker-arm -h which is held My invention relates to windlng machines by suitable clutch-devices on the oscillating bar 9 slides in a bearing j'secured"to the frame a and is connected to the rocker-arm h by a link is.

The traverse-bar which carries the threadguide ismade in two sections, the main poi tion- 9 being adapted to reciprocate. in a straight line parallel to the axis. of the winding spindle, as before explained, and the part 112. connected to the main-portion by a pin and slot arrangement which allows the inner end of the bar m to be moved.

laterally toward the winding spindle. The

" outer end of the bar m slides in a bushing n which is swiveled in an outboard bearing a fastened tothe end of an outrigger bracket 79 secured tothe main -fr'ame, see Figs. 1 and 2. Referring to Fig. 1, the bushing '11- has an annular enlargement n fitted to the bore'o of the bearin bushing t0 swing1 injt ebore and a stud 0?,

is screwed into t e bush-ing with its end enbushing from "displacement.

The opposite end of the threadguide-holderis adapted to. receive and hold the thread-guide 8' which is formed with the usualsl'ot 8', serving as a passage for? the thread or yarn the bearings of the thr'ead-.guide-holder on the traverse-bar allows the thread-guide .9 to oscillate to and from the winding spindle to adapt it tovfollow the taper of the winding on the nose of the cop. The bar m is formed with partial screw threads m cut y.- The arrangement of into the surface eccentric to its axis, see Fig. 5. Located between the two legs 7", 1" of the thread-guide-holder 1" is a nut t having its bore internally threaded, but .of sufficient diameter to slide freely over the threads on the bar at when concentric with the latter. Secured to the nut t is a disk or wheel 21. which has been termed the progression or contact wheel because it acts to contact with the rotatingv cop to turn the nut t and feed the thread-guide-holder along the traverse-bar. As before stated, the nut t is free to slide over the threads on the traverse-bar when concentric with the bar, but to maintain the nut normally in engagement with the threads m I provide a v spring 42 secured to the th'read-guide-holder 7* and arranged with its free end bearing on a flange u on the wheel to. During the winding, when the thread-guide s bears against the cop, as shown in Fig. 5, the effect of the spring a will be to keep the, nut 25 en aged with the threads on the bar m, but y swinging the thread-guide-holder 'r upward this efi'ect of the spring 4) W111 be "annulled and the nut will return to a position concentric with the bar. In this way the nut can be disengaged from the threads on the traverse-bar so that the thread-guide may be returned to its initial position at the end of the spindle, after one cop is completed, tostart the winding of a new cop. The means for maintaining the periphery of the progression Wheel u inclose PTO-X? imity to the winding spindle at thebegmning of the winding, to build the formatlon cone or heel of the cop on which subsequent layers are wound, is similar in general respects to that clescribedin the patent be fore referred to and will next be explained.

As before stated, the two adjacent ends of the sections 9 and mof the traverse-bar are joined with'a pin-and-slot connect-ion. The

end of the bar 9 is slotted at g and also bored with the transverse hole 9?, see Figs. 3 and 4. Inserted in the slot g s a plate 2 formed with a portion which-abuts the back 3*of the slot 9 A pin 4 is driven down through the rod and the plate to secure the latter in its position in the slot Q2 and the.

portion which abuts the back of the slot acts ,to steady the plate to prevent play. A slot5 is provided in the plate 2, extending perpendicular to the rod g. The end of the rod 411/ is also slotted at m to receive the plate 2 and drilled with a transverse hole sizes of tubes.

on the cam face 8. The plunger 9 is turned down throughout a port10n of its length to spring 11 is held under tension between the end of'the bore m and the shoulder 10 and acts to force the end of the plunger against the cam face 8. Preferably, this end is slightly rounded to adapt it to slide smoothly on the cam.. The effect of this arrangement is to normally maintain the bar m in axial alinement with the bar 9, as illustrated by dotted lines, Fig. 8, with the pin 6 at the back end of the slot 5. The rear end of the bar m can be swung in toward the winding spindle against the action of the spring pressed plunger on the cam, as shown in Fig. 1, but when the lateral pressure at the end of the bar is released the plunger 9 acts on the incline of the cam 8 to return the bar to its normal position.

The means for swinging the end of the bar m toward the winding spindle consists of-a guide or former 12 having an extension to move with the latter along the bar, see

Figs. 1 and 2. Referr-ihgto Fig. 5, a tongue 26 on the bearing 28 fof the yoke 27 projects into a lon 'tildinal slot 31 in the bar m to keep the yo e from turning on the bar and maintain thearm'13'of the yoke in position to bear onthe arm14 ofthe former 12.

In the patent previously referred to the former 12 is shown attached to the end of the bar gin a manner to allow the arm 14 being adjusted toward or; away from the winding spindle, but no provision is madefor changln the angle of the arm. The

arm 14 is a justed laterally in relation to" the winding splndle to adapt'the machine to wind cop's of ifi'erent diameters on difi'erent When cops of different diameters are wound either on the same or diflterent'. diameters of tubes different sizes of contact wheels are used, and inorder to set the wheel with its periphery close to'the -Winding-spindle at the start of the winding the arm 14 must'be adjusted .in relation to the spindle. It has also'bee1 found desirable to change the angle of tlie former arm in some instances for different classes of materials. In winding relatively coarse yarns of cotton or other soft material the coils have a considerable inherent'clinging tendency and are not easily displaced so that the cops can be wound with a comparatively steep taper or blunt nose. With hard or fine yarns such as Sllk or linen, however, the coils or the formation 0 of'winding are more apt to slip or. become I displaced and therefore the cops cannot be wound with such a steep taperbut must be built with a relatively sharp nose. It will be obvious that the .angle of the former arm 14 regulates the ta er of the heel of the cop i the ends of the layers of winding which overlap each other at their opposite ends to form the conical nose. It will therefore be seen that the taper. of the heel of the cop controls the taper of the nose and consequently the latter can be regulated by changing the angle of the former arm in relation to the axis of the winding spindle. It has been found in practice that material change in the taper of the cop is not often required, but when such a change is necessary the adjustment must be made very carefully andprecisely by a competent person in order to secure the best results. The ordinar operator is usually not enough skilled in t e windin art to knowthe rig t degree of taper forld fierent classes of material and therefore it, has been found expedientto arrange the device so that under ordinary "conditions the angle of the former arm Wlll not be materially changed in changing its lateralrelation to the winding spindle. With this object in view I; have devised an arrangement whereby the arm 14 can be adjusted laterally in relation tothe winding spindle under ordinary conditions without altering its an le of inclination to any mechanic familiar with the machine can by at. extent; and w ereby iii-addition a skilled changing certain parts .of the mechanism adapt the arm to further adjustment to alter its angle of inclination materially in relationfto' the axis of-the spindle. These devices for providing the adjustments described and for normally locking the armagainst one of the adjustments form the essence of the present invention andwill now be described; I j

' As before explained, the former 12 is secured to the end oi the section'g of the trav-' ,erse-bar' which projects fromthe bearing onthe frame '0 of the machine. The plate 2 at the endof the-bar g is formed with an extension lfi projecting at right angles 'tothe axis of the bar and the former 12 is fastened thereto bythe means now described; The inner end of the former .12 has a slot 16 throughwhich the-pin 4 at the end of'the bar 9 projectsand a second slot 17 is provided ,adjacent'the .arm 14. The extension 15 of the plate 2 is also formed with a laterally extending arcuate slot 18. A- screw 19 having a washer 20 under its .head extends down through theslots 17 and 18 with its end adapted to screw into, alock-plate 21,

the latter shown in detail inFig. 6. Re-

--ferring to Fig. 4, the lock-plate 21 isv provided with a hole 22 at one end adapted to receive a pin 23 projecting from the under side of the phtte 2. At the oppositeend of the plate 21 is a-pin 24'adapteds to enter a hole 25in the. extensi0n'15 of the late 2 to retain the-filatefrom turning on.t e pin 23. Between t e pin 24 and hole 22 is the; threaded hole. 30 for receiving the end of the screw 19.

For usual conditions of winding the machine is assembled with the lock-plate 21 arranged with one end held by the pin 23 and the opposite end by the pin 24 projectlng up into the hole 25. This brings the hole 30 in a position 'substantially' midway or: the length of the slot 18, as illustrated in Fig. 1. The former 12 is attached by placing it on top of the extension 15 of the, plate 2 with the pin 4 projecting 'up through the slot 16- and the 'screw '19 screwed down slots 16 and .17 being provided to allow such an adjustment. Inthe' Wardwell patent previously referred tothe slots in the former 12 are shown in alinement so thatlateral adjustment of the -former arm is in a straight line. It- .will be noted that in the present showing, however, the slots 16 and 17 arefnot in exact alinement but have-.a slight inclination one to the other. -This arrangement of the slots results in'causing a slight changein the inclination of the former. arm

as the former 12 is moved. from one extreme of position to the other, but this change is almost negligible. Itspurpose' is to vary very slightly the form .of the heel and noise of the cop in accordance withchanges. in diameter oft-he latter for, certain reasons. These slight changes need not be considered further, however, since they are.

'not relatedto the prime purpose of the present invention. In fact, the operation. of my new .device' would be the same if the two slots were arranged in alinement as in the patent'previously referred to. The essence of my new improvement resides in the de-y -vice which provides for a liberalad.'ustment of'i'the former armior changing rom one extreme of taper to the other irrespecformer.. A

In; order to I'nakethis last mentioned change in the angle of the former it is necessary to first remove the" screw 19 and release tive of the lateral displacement of" the the lock-plate pin 24 from engagementswith the hole 25 in the extension 15 of the plate 2. The lockplate 21 is then turned with its other side up against the extension 15, as"

shown in Fig. 4. In this position the pin 24 projects downward so that it is away from the hole 25 and when the screw 19 is replaced it can be moved back and forth in the slot 18 with the lock-plate pivoting on the pin 23. In other words, the lock-plate when in theposition illustrated in Fig. 1 is not restrained from lateral movement at its outer end and hence when the screw 19 is loosened slightly the former 12 can be swung about the pin 4 as a pivot with the screw sliding in the slot 18. In this way a material angular adjustment of the arm 14 is provided for in whatever position the arm may be in lateral relation to the spindle, so that almost any degree of taper, within certain limits, can be given to the ends of the "cop.

It will be seenthat my improvement provides a' practically fool-proof device which prevents inexperienced operators from tam-, pering with adjustments which must be made very accurately by those skilled in'the art.

While the mechanism allows the operator to make adjustments which are obvious and dependent on fixed conditions, only one having intimate knowledge of the machine and therefore particularly-compe tent can make the fine adjustments which must be based on good judgment and long experience. In other words, the ordinary operator from an examination of the machine will not become cognizant of the fact thatthe device can be set for a wide range of angular adjustment of the former arm and hence he is prevented from making changes that can only be advisable under certain 1 conditions. When such ,changes are necessary the machine expert or I other skilled workman can, by simply reversing the position of one element, adapt the mechanism to be adjusted as required.
