BYRON E. woonoocx, EUGENE r. MoNNra', AND ALBERT c. nEEsE, or sommen, PENNSYLV VERSE 75T To all whom t may concern.'

Be it known that we, BYRON E. Wooncook, EUGENE F. MONNIA, and ALBERT C. REESE, citizens of the. United States, and residents of Scranton, in. the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Traverse Mechanism, of which fthe following is a specification.

Our present invention relates .to improvements in traverse mechanism designed for use intconnection with silk winders, spinners and doublers, or other similar and analogous devices. l

'One object of the invention is to provide a simple, economical and durable device for operating the two traverse bars which cooperate with two sets or rows of winding bobbins or spools from a single lever common to both bars, instead of from two separate levers, as .has been customary.

Another object is to provide traverse operating mechanism of this character which can be readily shifted or adjusted to produce {,onger or shorter strokes of both traverse ars. f

Still another object is to provide in such a construction, means for readily adjusting the position or stroke of each traverse bar independently of the other.

The invention aims further to provide a construction which maybe readily adjusted to give a longer stroke to one traverse bar than the other, whereby longer bobbins can be wound on one side of the machine, and shorter ones on the other.

The invention further aims to rovide a construction in which a differential stroke will be .iven to each traverse bar, or more specifica ly, an arrangement by which while the length of stroke of each traverse bar will remain the same, its placement or range may -be shifted automatically to a slight degree with each successive stroke, thereby avoiding any danger of the threads becoming tangled when being wound or unwound.

With these and other objects in view which will hereinafter appear, the invention includes the novel features of constructionand arrangement and combination of parts hereinafter described, and particularly defined in the appended claims. l

An embodiment of our invention is illustrated inthe accompanying drawings, lin

Referring by reference characters to these drawings, the numeral 1 designates a portion of the end' frame of the machine (at the power end) to the ends of which, the side rails 2 are attached, each of which carries a plurality of brackets 3 corresponding to the number of bobbins on each side of the machine. A horizontal shaft 4c, suitably journaled in the bracket bearings beneath these brackets, carries rollers 4 which are designed to frictionally engage with rollers 5a on the ends of the bobbins 5 and rotate thesame by frictional engagement therewith, the brackets being provided with recesses 3h into which the spindle ends' 5b may be dropped, the recesses being of such depth as to allow the rollers 5a of the bobbins to come in contact and be supported by the periphery of the rollers or friction discs 4?. Other slots of less depth are provided, as indicated at 3, into which the ends of the bobbin shafts maybe seated when it is desired to stop any one bobbin without stopping \the operation of the entire machine. The horizontal shafts 4 are driven from shaft 6 through the intermediary of spiral gears 7 and 8, shaft 6 being driven from any suitable source of powerV in the customary or any desired manner. Associated with each row of bobbins or spools is a traverse bar 9 which carries a plurality of thread uides 9a of the usual or any desired form. e parts thus far described are such as are customary in winding machines of this character.

For operating the two traverse bars on opposite sides of the machine, we provide a lever 10, of the first order, fulcrumed at l0a fixed in vertical center line of end member l of the machine. 'Preferably SED bracket 11 is' secured to the frame by bolts passing through vertically elongated slots in the end frame (F 7) which enables the lever to be accuratel positioned vertically during erection. he said lever 10 is preferably so fulcrumed as to be capable of lengthwise adjustment for the purpose of giving a longer throw to the` traverse bar on one vside of the machine than on the other, as will hereinafter more fully appear. The preferred manner of securing an adjustable fulcrum isillustrated in the drawings,'in which it will be seen that the bar 10 has an enlarged or hub portion 1()b which rests upon the upper face'of the bracket 11, "and hub 10b having a vertical cylindrical passage through which passes the stud bolt 12, the lower end of which has a reduced portion Which passes through an elongated opening 11a in the bracket and is locked in position therein by a securing nut 11b threaded on the lower end of the stud bolt.

Preferably we use the stud bolt as a support for a spring to exert pressure on the lever, tending to rock it normally in one direction, and in the preferred embodiment of our invention shown in the\drawings, this is accomplished b-y providing a torsion coil spring 13 encircling the portion of the stud bolt which is projected above the surface of the lever 10 for this purpose, the end 132l of the spring being connected with the lever, and the other end being connected with a collar 14 which is locked to the upper end of the stud by a locking set screw 14a. lt is obvious that by loosening the set screw and turning the collar by the use of any suitable tool cooperating with kerfs or the like in the collar, the spring may be adjusted to any desired tension.

The lever is rocked by the spring in one direction to secure corresponding movement of the traverse bars connected to the ends of the lever, movement in the reverse direction being effected by a cam 15 which is driven from the shaft 6 through mechanism hereinafter described, this cam cooperating with a roller 16 carried by a bracket 17 adjustably secured to the lever by a locking bolt 17a Working in a slot 10c in the lever 10. As this cam rotates, through its cooperation with the roller 6, which is held in contact therewith by the spring 13 above described, the lever is rocked on its fulcrum and hence the traverse bars are reciprocated, as will be evident.

It is desirable that the cam 15 have a differential action so that on each successive stroke the placement or range of the traverse bars and thread guides will be slightly shifted tlfough the length of stroke will -always remain the same, and the thread guides will be stopped at the ends of their movement at different points relative to the ends of the bobbin. This prevents tangling Moeller of the threads when the thread is rapidly unwound from these same bobbins when they are placed on the next machine in the process of spinning, doubling, etc. This we accomplish by the mechanism which will now be described.

A bracket 18 is adjustably connected to the end frame member 1 preferably by means of bolts 18 passing through the bracket member and through elongated slots in the frame member. The bracket has an offset end or portion 1811 to which is secured a stud 19 conveniently by forming the stud with a threaded end which projects through an opening in the bracket, the .stud having a thrust receiving shoulder or collar 19a on one side of the bracket arm, and a clamping nut 19b on the other side with preferably an interposed washer.

A worm wheel 20 is rotatably mounted on this stud being retained thereon by a collar portion 19c resting in a recess within the body of the wheel, and this 'worm gear meshes With a worm 6a on the shaft 6. Stud member 19 has a stud extension 19d which is eccentrically positioned relative to the stud portion 19 and on this stud portion 19d is journaled a bushing or sleeve 21. rlhe inner end of the sleeve has fixed thereon, or integral therewith, a gear 2li1 which meshes with an internal gear 20a carried by, or formed integral with the Worm wheel 20. The bushing or sleeve 21 carries at its outer end a sleeve or hub member 15a of the cam 15 which is rigidly secured thereto.

The inner face of the gear 21a is formed inclined to a plane perpendicular to the aXis of the gear, this inclined face in effect constituting a cam surface indicated at a which' cooperates with a raised portion or projection a on the adjacent yface of the worm wheel or gear 20.

It will thus be apparent that' as the worm wheel 20 is rotated the gear 21*l will be rotated by the internal gear 20 which will rotate the cam 15 and impart the hereinbefore described movement to the lever 10 and traverse bars. Thespur gear 21a has less teeth (preferably 7 less) than the internal gear 20, consequently it rotates slightly faster than the internal gear and the worm wheel 2O which arcl integral, and this difference in relative speeds causes the round knob a to travel around the cam surface a, giving the axial movement to the art 21 carrying the cam. The essential part ofJ the designto produce the differential motion is to have two gears with a different number of teeth meshing into each other to produce different speeds of rotation. By reason of the adjustable connection of the bracket 18 I to the frame, and the adjustable connection of the roller 16 to the lbar 10, it will be seen that the gear assembly above described, can be moved towards or from the fulcrunx neoa'eei of the lever dto thus produce a longer or shorter'stroke of the traverseibars. lt

ulcrum of the lever 10 as above described.'

The sleeve 21 is held in position on the stud portion, or shaft projection 19d with the cam face a of the spur gear 21 yieldingly pressed against the projection or raised portion a by a helical spring 22, which bears at its inner end against the end of the sleeve, and at its outer end against a plate or washer 23, which is held in position by a boltj24 which extends through the spring and has its inner end tapped into the end of the stud or shaft projection 19d.

The traverse bars 9 are connected to the respective ends of the lever by connecting links 25 and the connection of the link with the lever 10 is preferably made adjustable bin, of a traverse device, and

lengthwise of the operating lever, whereby the length of stroke of the traverse bar may be adjusted. rlhe preferred manner of eiecting this adjustment is shownin the drawings, in which each end of the lever 10 is -provided with a pair of projecting lugs 101 through which pass an adjusting screw 27 which carries a bracket 28 to which the end of the link 25 is pivotally connected.

The link 25 is also adjustably connected to the traverse bar 9 in the customary manner.
