WINDING-MACHINE.

To all whom it. may concern: Be it known that I, SIMON W. WARDWELL,

a citizen of the United States, residing in Providence, in the county of Providence and State of Rhode Island, have'invented new and useful Im rovements in Winding-Mach nes, of whic the following, is a specifica tion. My invention is a winding machine for producmg universal wound cops'or yarn packageaof cylindrical form, with taper ends, the "winding. being done in advancing conical layers, so that the growth of the package is by longitudinal extension instead of diamet'.

rically. These cops are employed as filling or weft in weaving cloth and their form is fully disclosed in my ending application,- Serial No. 323137, filed lune 23,1 906.

The following specification is a complete description of the invention, illustrated by the accompanying drawings, representing, re-

spectively: Figure 1, afrontelevation of the machine; Fig.2, a plan view; Fig. 3, an enlarged diagrammatic sectional view of the cop, showing the disposition of layers Fig, 4, .:a part sectional view on the line AA,-Fi -1;'= looking in the direction indicated by the arrow; Figs. 5, 6, 7, 8 and 9, detailsot the "'Is'tructure.

The machine herein described is designed to produce cops having a substantially fiat base end and a tapered nose or delivery end. Referring to Figs. 1 and 2,- the tube or bobbin2 on which the yarn is wound is carried on a Winding'spindle or c'op holder 3 which is adapted to be driven by a suitable agency, as the tight. and loose ulleys 4 and 5. Adjacent and parallel to t e winding spindle 3 is a reciprocating member or bar 6 on which is mounted the guide holder 7 which carries the yarn depositing guide 8, and during the winding travels along the member 6.,

' To produce a'substantially flat-based cop of the character described, it is necessary to.

deposit theyarn in superimposed cone-like layers of different length of traverse, as indicated in Fig. 3, until a base or core, composed of yarn and having the requisite form, is secured. Then the winding proceeds with a uniform but shifting traverse until the desired length of cop has been secured.

Reciprocation of the guide is performed by two oppositely'rotating threaded screws 9 and 10 of fine pitch and coarse lead, best Specification of Letters Patent.

Patented March 10, 1908.

' shownin Fig. 2, driven from the spindle through a suitable train of own in Figs. 1 and 2.

In bearings 11 and 12 is a longitudinally gears s reciprocatable rod or bar 13 to which is secured a depending arm 14, near whose lower end are two screw threaded portions or pertial nuts 15 and 16, made to respectively engage the screw 9 or the screw 10, see Fi 9. The arm 14 has a slidable bearing on :1 r0 ,17, running parallel to the rod 13, and this bearing is adjustable laterally to allow the arm 14 to oscillate when the nut portion is thrown from one screwto the other. Mountedon the rod 17 are the instrumentalities for controlling the shifting of the arm 14, one of them, 18, fixed onthe rod and adjusted by the longitudinal movement of the rod sliding in its bearings, and the other, 19, slidable on.

the rod and adjusted by separate means hereafter described.

Fig. 8 is an enlarged detail view of the controlling and locking mechanisms for the arm 14. Between the rod 13 and the int portion, the arm 14 is formed with a cylindrical sleeve 20 having .a relatively large bore, to provide clearance for the rod 17 which extends through it. The ends of the sleeve 20 are turned down and forced onto them are the thimblcs 21 and 22 having offset bores, 23 and 24, at their ends, eccentric to each other and to the bore of the sleeve. Slidablepn the rod 17 are two flanged bushings or plungers 25 and 26 arranged with their flanges, 27 and 28, projecting into the recesses between the ends of the sleeve. 20 and the ends of the thimbles, so that the movement of the plungers is limited. Surrounding the rod 17, between the plungers, is a coiled spring 29 tending to press both of the plungers outward .through the bores of the -th1mbles.- The plungers are formed with shouldered portions 30 and 31 which exactly fit the said eccentric bores. bores 23 and 24 are not coaxial, only one plunger at a time can be engaged with its bore in the th-imble. The engagement of'one of the plungers' with its appropriate bore looks the sleeve 20 in position to engage the arm 14 with one or the other of the screws 9 and 10.,and to release it, the plunger must be ressed in, compressing the spring] l vhen the sleeve 20 is then shifted laterally, the spring acts to force the opposite plunger into its bore, and the sleeve 20 is thus locked in its other position, with the arm 14 engaging the opposite screw.

The instrumentalities for controlling the shifting of the arm 14 consist of the contact pieces32 and 33 of the members 19 and 18 and'iit-he springs 34 and 35 also mounted on said. members and adapted to engage opposite sides of the sleeve 20 and shift it one way or the other. The operation of these de vices is as follows: Assume that the arm 14 is-engaged with the screw9, and under action of the latter is moving in the direction indicated by the arrow B, Fig. 8. The plunger 25 will then be in engagement with its bore 23, but when near the end of its traverse, the contact piece 32 strikes the plunger 25 and forces it from its bearing in the thimble 21, compressing the spring 29. At the same time the spring 34 contacts with the thimble 21 and oscillates the arm 14, thereby throwing the nut portion into engagement with the screw 10. This brings the bore of the thiinble 22 concentric to the plunger 26, and the latter, under action of the spring 29, is forced into its bearing in the thimble, thus locking the arm 14 in contact with the screw 10, the parts then in position shown in Fig. 8. The arm 14 is now traversed in the opposite direction, the rotation of the screw 10 being opposite to that of screw 9; and when the arm reaches its other extreme of travel,

the same action occurs as previously de' scribed, this time the contact piece 33 acting on the plunger 26.

It has been explained that the cop is wound by first producing a yarn base of tapered or conical form, and further that this was secured by commencing the cop with winding of short traverse and then gradually or intermittently changing the length of traverse until the desired taper and diameter of cop is secured. This is indicated in Fig. 3, showing how the cop base is built up.

The mechanism whereby the building is eflected is as follows: It has been stated that the member 19 is shiftable along the rod 17. From the foregoing it is obvious that any change in the position of the member 19 longitudinally of the rod must affect the length of traverse of the arm 14, because it changes the distance relation of the contactpiece 32 and the contact piece 33, which effect the reversal of movement of the arm 14. The shiftable member 19 is preferably formed as an arm or bracket fastened at its lower end to a rod or preferably a tube 37 mounted in the machine frame at 38 and in a stand 39. To'the top of the tube 37 is fastened a key or spline 46 which extends through the bearings 38 and 39. Ynder the influence of the tension spring 41 the tube 37 tends to move in the direction indicated by the arrow C, said spring extending from the tube 37 to the holding piece 42. Movement under influence of said spring is, however, prevented by the stepped detent or ratchet 43 which, mounted to rock on the rod 6, engages the'end 44 of the spline 40, see Fig. 5. The ratchet 43 is secured to a rocking frame 45 having an arm. 46 Fig. 4 which bears on the base of the cop being wound and by which it is rocked on the rod 6 as said cop increases in diameter at its base, or rather as the core increases in diameter,-see Fig. 4. finding is started with the member 19 in the position indicated in Fig. 1, when the end 44 of th spline 40 engages the first step, 47 of the ratchet, and the guide 8 has its shortest throw. As the yarn is deposited on the tube or bobbin, it presses on the arm 46, gradually moving it in the direction indicated by the arrow D, Fig. 4, until the step 47 has been moved away from the spline 40, which immediately moves, under action of the spring 41, to the step 48. This reoccurs, the spline successively moving from one step to another, each time increasing the length of traverse an amount equal the extent of the ste until the last step is reached. At this tlme the full diameter of the cop has been reached, and it is necessary to so continue the winding with the extent of traverse attained that the cop shall grow by longitudinal extension and not by diametrical increase: that is, the reciprocating thread guide 8 must be caused to feed slowly along the reciprocating rod 6.

Connected with the reciprocating rod 13 is the member or bar 6, on which is mounted the guide holder 7. The latter is forked, each branch of the fork embracing the bar 6, and between the branches is a rotatable nut 49 which engages said guide holder 7 with the bar 6 and feeds it along said bar.

Formed in the bar 6 are partial screw threads 50, having an axis 51 which is eccentric to that of the bar 6, see Fig. 7. The nut 49 might be formed to engage the rod 6 directly, but, preferably, it has a bushing or sleeve 49 screwed into its bore, said sleeve being formed with internal scr w threads which are maintained in engagement with said partial threads on the bar 6 by the spring 52 attached to the guide holder 7, see Fig. 2. By turning the guide holder on the bar 6, a sufficient distance rotatively, the action of the spring 52 forces the nut out of engagement with said partial threads lcaving the guide holder free to he slid by hand along the bar 6 without hindrance.

The partial screw threads 56, the nut -19 and the spring 52 are so related that when the guide holder 7-is in winding position--- toward the spindlethe nut 49 through its sleeve 49' is engaged with said )artia scrrw threads, and any extent of oscil lation of the guide holder incident to following d1" taper of the cop nose, will be insutlicicnt o with-- draw the nut from such engagement. in this position, whatever rocking movement the guide holder has is automatic, derived from the action ofthe machine. But if it is desired-to move the guide holder manually, as when it is moved back toits starting oint to commence a new cop, it is only need 1 to rock the guide holder back from the winding spindle through about a half turn and then s ide italong the-spindle to any desiredposition, as described.

The automatic feeding of the guide holder 7 along-the bar 6 is secured by action of the cop. On the'nut 49 is a wheel 54 of such diameter as to be engaged by the surface of the cop at its full diameter, as indicated in Figs. 2 and 4.' Every time,-therefore, that the guide 8 returns from the point 55 of the copsnose, in any layer Fig. 3, and reaches the portion of the Winding of largest diameter 56, the wheel 5-1 is engaged and rotated slightly, causin the guide holder? to advance slightly 2. oiig .the rod'or bar 6, which actually occurs at each reciprocation of the guide 8.

As previously stated,- the cop may bewound 'witha substantially fiat base, but it has been found preferable to give a very slight ta er to the base in order to make it more sta le. When formed with a perfectly flat base, if the co is subjected to rough usage, the outer coi s are liable to be pushed over the end andlin delivering the yarn will drag across the edge, causing abnormal tension. By forming the base slightly tapered, as shown in Fig. 3, the outer layers are more firmly supported and are less liable to derangement. I v

The mechanism for controlling the traverse of the thread guide to effect the taper of the base consists of means for automatically adjusting the position of the contact member 18. It will be evident that, if the member 18 is shifted gradually in the direction indi cated by the arrow E, Fig. 1, the starting point ofeach layer of yarn will be correspondingly adjusted toward the outer end or nose. of the cop, so that the yarn will be built up on an angle instead of perpendicw larly to the tube.

As before described, the member 18 is securedto the rod 17,being fastened by a set screw 57 extending through it and binding it on the split bushing 58, which, in turn,- binds on the rod 17 The bushing 58 extends through the bearing 59, being slidable therein, and the rod 17 projects slightly beyond the end of the bushing. Bearing on the end of the rod is a spring 60 fastened at 61. The spring 60 tends to force the rod 17 in the direction indicated by the arrow E, but the movement of the rod is controlled by an arm 62of the rocking frame 45 against which the end of the rod bears, see Fig. 5.

The frame 45 rocks outward in the direction indicated by the arrow F, Fig. 4,

under the influence of the growing cop, acting on the arm 46, and the frame also has a lateral movement sliding on the rod 6. p This latter movement is. caused by the rod '17 bearing'on the arm 62 under tensionof' the spring 60, and is regulated by the ratchet member 43. O )posite the series of steps 47 and 48 the mem er 43 is formed with a finer ratchet having steps 63, etc. These steps are engaged by the extremity of a screw .64

adjustable in the bearing 39 on thefranieof the machine. It will beevidentt that after. a certain thickness of layer of yarn, has been deposited on the tube 2, the frame 45will be rocked under the influence of the arm 46 until one st-ep'63 is removed from the screw 64. The s ring 60 then acts,- through the rod 17, to s ide the frame 45' laterally on its bearing until the next step of the ratchet is engaged by the screw 64, and this action continues during the building 'up of thebase of the co The member 18. is thusshifted gradualy to vary the starting oint of the" successwe layers of winding, so t at, the base of the cop 1s g ven a slight taper as before I,

explained. I I

The operation of the winding machine, as a whole, has been described. as effected through the tight and loose pulleys 4 and ,5.

-When the belt is on the loose pulley 5, the

machine is stopped. Vt'hen the belt is thrown upon the tight pulley 4, the machine is in operation. I p

The position of the belt is controlledby the belt shifter 65 which is movable manuallv into engagement with the lock 66 to.

shift the belt to the tight pulley; and when released by the lock 66, is moved automatically by the spring 67 to shift the belt to the loose pulley. gaging position by the spring 68, see Fig. 6, and its non-engaging end is connected with a bell crank lever 69, to which is v also, connected a rod 70 which extends substantially The lock 66,isheld in its en.- I,

parallel with the winding spindle 3' tofa vertical fulcrumed. arm 71. By moving either the rod 70 or the arm 71 in :the direction indicated; by the arrowiG, Fig.1, the lock 66 is withdrawn from engagement with the belt shipper 65.

guide holder 7 when the full length of co f has been wound, to. stop the-windmgby gaging the belt shipper aforesaid.

On the rod 70 is'a block or member'72 devised to be engaged vbyfthe Isen- The wind or number ofturns ib'e be moved along the rod 17 and adjusted in relation to the contact piece 32, and this adjustment regulates the length of traverse oi the thread guide. in my U. S. Patent 5670122. issued March 19, 1901, is fully ex plained the method of changing the gain by slightly changing the length-0t tr'averse ot the material depositing guide.

As the winding spindleS and screws 9 and 10 have a uniform relation as regards rotative speed, it follows that the change in length of traverse thus etlected causes a change in the number of spindle rotations per traverse or reciprocation ot the guide. In other words. assume that the guide has a traverse of one inch, in which traverse the winding spindle makes four turns or rotations. The traverse is extended 1/100 in. no change occurs in the rate of traverse of the guide per minute or in the speed of spindle rotation per minute, it necessarily follows that the spindle must have made -1 4 100 turns while the guide has moved 1 1/100, instead of four turns during 1" travel of the guide, or the number of turns p er traverse has been increased t/100.

Because of the effect of change in length of tin verse on the gain, if the closeness of the wind is to he maintained throughout the core of the cop. the number of steps in the ratchet .43 should bear some definite relation to the ultimate number of winds on the nose of the cop. preferably being some aliquot part of that number, and the steps should be made with such exactitude as regards their individual extent, as to insure the requisite degree o1" closeness in the layers corresponding to each step. For example, the number of winds with which the yarn is deposited on the nose of the cop might be nine, and the ratchet has nine steps, so that the first step of the core wound with one wind. the second with two winds and so on until the core is completed and the winding accomplished with its 'l'ull nine winds.

It will be evident that modifications might he made in the form and arrangement of the devices herein described without departing from the scope of this invention.
