` met: tan-wmnmu 'uacnmn- To all -wwm it my concern:

Be it known that l, Gnonon E. ALLEN, a citizen of the United States, residing in the 'city and county of Philadelphia, State of Pennsylvania, have inventeda new and useful Package-Winding Machine, of which the following is a specification.

My invention relates to winding machines, and more particularly to that class of machines which wind yarns or threads into a package through the medium of a suitable core and has for an object to provide a mechanism by means of which the winding operation takes place in such a manner as to produce a wound article or package which is syetrical in appearance, accurately formed throughout and in which the superlposed layers or convolutions of thread are hound together so that thereV is no opportunity or danger of the package becoming loosened, nnwound cr disintegrated in any part or parts.

' llt has for a further object to provide a winding mechanism adapted for use with all grades of yarn or threads so that the softest material may be wound just as accu rately and effectively Vas the harder or coarser yarns.

My invention more particularly coinprises a mechanism` for guiding to and placing a thread or yarnupon a package so as to conform to and allow for the varying diameter of the usual tapered yarn package as well as the tendency of the package to build up at the ends faster than throughout the body portion thereof. ll accomplish this end by employing a combination of elements adapted to cause a varia- .tion in the speed of the laying-on mechanism so that the end and body portions of the package are laid not only with a speed proportion to the change in thel package diameter, but also with regard to the dead centers of the laying-on mechanism.

ln winding packages of tapered form it is evident that one end of the package has a tendency to build up much faster than the opposite end, while the oppositeend also has a tendency to build up somewhat faster than the body portion of the package, and therefore it is one object of my invention to compensate-the laying-on mechaso that it moves-amally of the package at varying speeds and with a quick re movement at the respective ends of the'- package,

, found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which myv invention consists can be variously arranged. and organized and that my invention is not limited tothe precise arrangement and organization of these instrumentalities as herein shown and described.

Figure l represents a plan of a winding machine embodying my invention; Fig. 2 represents a side elevation of the same; Fig. 3 represents an elevation of the side of the machine oppositel from that shown in Fig. (2; Fig. d represents a section on line w-- of Fi 3.

. Re erring tothe drawings, like numerals indicate corresponding parts.

1 designates the main driving shaft of v the winding machine, the same being mountin practice the shaft 1 may he of any length desired,'according to the number of Vforms or packages to he simultaneously wound,

but as these winding forms areall similar.

to the one shown in the drawings vas the preferred form, l have for the sake ofclearness confined the following description as well as the drawings, to but one .of the winding forms andits adjuncts. 'lhe shaft' 1 is driven from any suitable source of power and carries on the end thereof a bev- 'eled pinion d meshing with a beveled gear 5 ed to the counter-shaft 6, thislatter he-Y ing mounted in suitable journals 7. The shaft 6 also has keyed thereto a gear 8 Y -ma 1 meshing with asimilar gear :9, upon, the

shaft 10, which is preferably arranged par- .el to the shaft tl' .and mounted'in the journals l1. dttention is direc to the substantially elliptical configuration of the 11o t ars 8 andu, since the motion u o the shaft 6 to the shaft l0 isa peculiar arranged with respect to its short diameter,

the function of which construction will later appear in the description of the other adjuncts of the mechanism and its operation.

12 designates a disk, plate or like device mounted adjacent one end of the shaft 10 for rotation therewith, and having a crank pin 13 adjustably secured thereto at a suitble point, diametrically opposite to which pin there is a balance weight 14 for the usual purpose in crank driven mechanism.

15 designates a connecting rod secured at one end to the pin 13, and at its opposite end to a wrist pin 16 carried by the reciprocable rod 17 which I prefer to call a traverse rod since it is one element of the layingon mechanism. vThe rod 17 is mounted for sliding movement in a guide or guides 18; the outer or intermediate guides necessary are not shown since the outer ends of this rod, as well as its connections, are omitted for the reasons heretofore given in connection with the shaft 1, but it will be understood that the end of the rod 17 is suitably supported and guided in any well known type ofguide bearing.

19 designates a thread guide comprising an antifriction eyelet or the like .suitably securedV to the rod 17 for receiving the thread or yarn 2O from a suitable source such as the reel 21, and delivering the same to the thread laying member 22 which is por sitioned in alined relation to the thread guide 19 and fixed for rotation upon the shaft 1.

23 designates a xed rod interposed between the reel 21and thread guide 19 with which the thread is engagedin order to properly direct it to the surface of the thread laying member 22 as will be apparent.

Vtrs- From the thread laying member 22 the thread passes direct to the package 211 and the latter receives its rotary movement through contact with the aforesaid member 22. In connection with the package 24 attention is directed to the fact that it is rewell known type of mechamsm may be employed for holding theV package in proper position with respect to the thread laying member, the said mounting embodying automatic features if desired for adjusting movably mountedupon a suitable support-v member there is a second angular groove 29,

the respective legs of which also form portions of a helix preferably concentric with respect to the helices of the groove 28. It

will further be noted thatin the preferred form of my invention the two grooves 28 and 29 are arranged at an angle of substantially 90 degrees with respect to each other, that is, the apex of one groove is positioned a quarter turn of the thread laying member from the opposite apexfor a purpose Vwhich will later appear.

In the present embodiment of my invention I have shown the thread laying member 22 as frusto-conical in shape to form a substantially similar shaped package, but it will be understood that I do not desire to be limited to any definite taper or`shape of thread laying member as the same may be varied in contour as desired in order to wind a package A of predetermined shape.

In the operation of the device a package form is placed upon its support adjacent the thread laying member 22 and held in contact relation therewith by suitable mechanism, so that upon rotation of the shaft 1 the said form will receive the required rotary movement and also move gradually as the winding increases in thickness. |Ihe thread 2O is Vpassed from the reel 21 about the bar 23, then across the face of the member 22 in a plane substantially normal to the axis of rotation of the drum where it is then secured to the package form. Rotation of the shaft 1 causes the member 22 and package form 24 to rotate together at substantially the same surface speed, and simultaneously with this action motion lis transmitted through the gearing and crank mechanism to the traverse bar or rod 17, which thereupon commences its reciprocating movement so that the thread passes alternately from one end of the member to the other. This movement causes the thread or yarn to be wound upon 'the package 2l inthe form of superposed helices, and the successive helical windings are built up one y upon another with uniform spacing between the strands/0 f each layer, thus giving'the wound pac age a symmetrical appearance as well as a.' structure incapable of disintegration.

In devices heretofore devised for winding thread and yarn, it has-been found that the incapaci packages are not uniformly wound, either vas to shape or to the density of the winding,

and the ends of the package will often be built up more than the intermediate portion so that the package breaks down in use orf becomes unloosened. y

1 am aware that it hasv heretofore 4been proposed to utilize cam grooves for causing .a winding mechanism to reciprocate and place a thread upon a form or package, but in practice such grooves soon become Worn and the lost motion. caused by this Wear so changes the relation or timing of the windingparts that the thread yis not uniformly placed and,l the resulting packageis unsatisfactory and defective. Furthermore, where the thread itself passes through a cam channel or groove, there is a decided ,tendency for the sharp edges of the cam to cut or break the thread, and when this occurs'and the broken end is replaced in its groove it frequently becomes caught in the surface of the cam and winds directly upon the cam instead of being guided to the package.

lin/my present construction l have devised*- a mechanism the partsof which are accurately adjusted and timed with respect to each other and the travel or stroke of the traverse bar 17 has a definite predetermined relation to the length of the package as well as to the longitudinal distance between the reversely arranged slots 28 and 29. Furthermore, it will be noted that the gears 8 and 9 are designed with such an eccentricity as to produce substantially a uniform movement to the traverse bar 17 with respect to the body portion of the package, that is, intermediate the ends of the thread laying member which ends are considered as the apices of the grooves 28 and 29. As a matter of fact, however, the action of the two afore- 4 said gears is such as to cause thetraverse rod 1'( to move toward the smaller endof the package with a slight lacceleration while in the opposite direction the reverse is true,

lthis movement of course being in accord with the` tapered form of the package. Adjacent each end of the stroke of the traverse bar 17 the gea-rs impart a sudden acceleration to the rod so that it'reaches the .end of the stroke at a maximum speed and begins its return movement with this speed and `then the velocity gradually decreases to the normal velocity for the body of the package and depending, of course, upon the direction of travel.

ln connection 4with the foregoing itwill' be noted that while the speed of the traverse bar is greater at the larger end ofthe package than itis along the body of the package to givethe reouiredquick return movement, the speed at the smaller end of the package is greater than either the speedy for the body portion of the package or for the larger end and the threads may be readily unwound.

ofthe same, and it will be apparent by ref-- erence to the gears 8 and 9 that when the traverse bar is at the end of its stroke adja-- cent the small end of the package the gear 8 will have its long diameter substantially horizontal and with its longest radiuson the side toward the gear 9 while the latter gear will be positioned with its long diameter substantially vertical and the shorter radius of itsshort diameter on the side toward the gear 8, thus giving the lrecluired higher speed for the smallcnd of the package as will be apparent.

Furthermore, in addition to eliminating any chance of the thread piling up at the .ends of the package it will be noted that at -the moment of changing the direction of movement of the ltraverscbar the thread thus forming substantially an4 auxiliary holder or guiding holder which takes up and distributes what would otherwise be a sudden tension upon the thread. This construction, therefore, makes it perfectly possible to wind the finest, softest and most delicate yarns or threads upon the package without damage, and also it follows that a package may be wound which is either soft or hard accordingv to the texture of the thread used, and l believe this to be an advantage not attained, so far as I am aware, by other package windingy machines` since suchniechanisms in present ,dayv use depend upon maintaining a degree of tension uponl the thread not at all practical for the winding of the :liner or softer grades of material. As a further point of advantage itmay be pointed outthat those soft grades of yarn have a tendencyto clingvor stick together when Wound upon a package so that when all grades of goods are wound upon. the

, same tapering package, it is very difficult to different taper so that provision may be made for the softer, finer threads, this be ing accomplished by employing a. package form having'a more acute taper so that the clinging action of the threads is overcome The change of speed of the thread placing mechanism and the consequent uniform spacing of the yarn upon the package insures the effective binding of the threads upon the package so that there are no eX- posed points' thr'ugh which loops-@bf the yarn may, be thrown outunder centrifugalV force, which is a tendency .which develops A more particularly when winding soft yarn.

LIt will nowl be apparent that I have de- .vlsed a' novel and useful 'construction of `winding machine which embodies the feaof advantage enumerated as desirable "tle statement of the invention' and the above' description, and while I have, in the present instance, shown and described .a

. preferred` embodiment thereof which has been found in practice to give satisfactory sacrificing any of its advantages.

and reliable'results, it is to be understood that the saine-is susceptible of modification in variousl particulars without departing from the spirit or scope of the invention or Having thus described mv invention, what I claim as new and desire to secure by LettersA Patent is :--l A 1.
