Be it known that I, ANKBE a citizen of the United States, residing at Winthrop, county of Suffolk, State of M sin Winding-Maclunes, of which the following description, in connection with the accompanying drawing, is a specification, like letters on the drawing representing like parts.

This invention relates 'to a machine for winding bobbins, and has for its object to giving the ment thereby to properly lay the thread on the bobbin; to provide a novel form of tension for the thread whereby the latter will be laid on the bobbin with a uniform tension part of the bobbin of small ,or large diamtion, all as will be more fully hereinafter described and then pointed out. in the appended claims' Y In the drawings wherein I have illustrated one embodiment of my invention,

bodying the novel features above described; Fig. 2 1s a side view; Fig. Sis a top plan view; Fi 4 is an enlarged sectional view on the line a:-w, Fig. 4:; Fig. 6 is an enlarged section on the line y-y, Fig. 1; Fig 7 is 'a detail of the stopping mechanism; Fig. 8 is a detail of the tension,

- The spindles- 3-on which the yarn mass m. is wound are supported in suitable'bearingsf carried-by a main frame 31 which may have spindle carries at its lower end a friction disk 32 which is adapted to rest on and be frictionally driven by a whirl 33 that is suitably. sustained on a stud shaft 34 carried' by the frame 31. The end of each spindle 3 projects down through the friction disk 32 thereon nd is adapted to set into' 1? the opening :in the whirl .whirh therefore, ot only supports its spindle -but acts as means for centering the;

fnanner bybelts 4 that exercisin shaft 5;

vThe yarn or thread 2% is laid on the bobbin by means of a thread. ide-Z which is given a traverse in a vertioa direction and which atthe same time isgradually elevated so as to'lay the yarn after themanner of the well known filling wind. The. thread guides are sustained in a rising-and fallin frame 8 which is gui ed in its movement y suit- PetentedDec.23,1913. I

able guides 37 formedon the irame 31. The

frame 8 has extending from op site sides thereof two arms 13 each of whie carries at its end a 101138 thatis engaged by a cam 12 fast on a cam shaft 11. The two cam shaftsll are sustained in suitable bearings 39 and each 'has thereon a; worm gear 10 which meshes with and is driven by a worm 9 formed on the driving shaft 5. This gearing is so timed as to give the frame 8-1ts rising and falling movement at proper intervals. One advantage of this construction is that the cams :12 act directly on arms rigid with the frame 8 and the motion from the cams to'the frames is not imparted through "fiexihle or other yielding connections which are less' liable to give. accurate and true movement than isthe direct connection hereinshown. It will be understood, of course, that the wei ht of the frame is 'suflieient to cause it to escend and to keep the rolls 38 in contact with the cams 12. w

The frameS has a rising and falling movement thrdugh a fixed distance d the necessary gradual elevation ofthe' bread guide for laying the thread after the-manner of the well known filling wind is accomplished by; The "usual resser or friction wheels 30 which have a screw-threaded engagement with rods 40 carried by the frame. In the construction herein shown these presser wheels 30, which arepreferibly made of wood, fiber, or similar materialgand which are provided with a roughened on friction surface, have each a hub port-ion iii'depending therefrom on which is lonselymounted a sleeve &2. Each sleeve 42- is embraced by a split collar 43 from'whicli projects' the stem 44 of the thread gguide 'l The-twtiiparts.

of each split collar'areconnected together by a clamping screw 45in a w uknown' nianner, and, byme'ans of. this; cons t rnctien ,it will. be obvious; {that each i Qtand? its thread guide may be ejuseeayveraeniya l we e as? w w e the sleeve ther by t itontrolj the ifi lfiti've 0 wheel 30. The sleeve 42 is capable of being turned axially about the hub 41 and by this means the axial positi n of each thread guide 7 can be .determ n d. Thescrewthreaded connection. be ween each presser wheel and its rod 40 is s cured by means of aspring arm 46 extending upwardly from the presser wheel and having its end 47 bent inwardly to'engage the screw-threads of the rod 40. Whenever during the downward movement of the frame 8 any of the .friction wheels are brought into contact with the conical or tapering face of the yarn mass m, said friction wheel will be turned slightly and during such turning movement will be raised on the rod in a manner well known to those skilled in the art and the thread guides are thus gradually elevated as the thread mass is built up. The advantage of being able to adjust the thread guide vertically relative to the friction wheels is to provide for building the thread mass of any desired diameter, for

it .will be obvious that since the spindle and the corresponding rod 40 have fixed positions relative to each other each presser wheel 30 will always contact with the thread mass at a point Where the diameter of the thread mass has a fixed length and, therefore, if the yarn guide is lowered, relative to the presser wheel the size of'tne bobbin will be increased, while if the thread guide is brought nearer the presser wheel the diameter of the thread mass will be less.

The device herein shown includes means for automatically" separating the friction disk of any bobbin from the whirl when the bobbin is of the proper size. As herein shown, each whirl has associated therewith a lever 48 pivoted to the frame at 4-9 and adapted when raised to engage the under side of the friction disk 32 and separate the latter from the whirl. Each "lever 48 has connected thereto a vertically-extending rod 89, the upper end of which extends through an aperture in a guiding plate 50 sustained by the frame 31., Each rod 89 is provided with a shoulder 51 which is adapted to engage a stop 93, as shown in Fig. 7, thereby to hold the lever 48 depressed. .A spring 52 secured at one end to each rod 89 and at the other e ncl to said plate 50 tends normally to elevate the rod. Each rod 89 carries an adjustable arm 54 which is preferably situated at an angle, as shown best in Fig. 2, and is adapted to be engaged by the prcsscr wheel 30 as the latter gradually rises. \Vhen the presscr wheel is elevated sullicicntly to engage the arm 54, the rod 89 will be thrown bhclnvardly thereby to disengage the shoulder 51 from the stop 9 and the spring 52 will then come into play to elevate the rod. thus bringing the lever 48 up against the under side of the friction disk and sewn-at ing the latter from the whirl. By making the linger 54 adjustable vertically a thread mass of any desired length can be secured.

The spindles rotate at a uniform speed and therefore when the thread is being laid.

on the portion'of thethreadmass of larger diameter, as shown in Fig. 1, the thread will be drawn much more rapidly from the supply than when it is being laid on the bare pindle or the portion of smaller diameter.

if a tension device'capablebf applyinga uniform tension on the thread were used,

the resultwould be that the thread would be wound tightly on the portion of large diameter, but would be wound more loosely on the portion of small diameter. In order to provide for laying the thread under anniform tension, throughout the" entire "thread mass I have provided a tension detion of the thread mass of smaller diameter 'and being least when the thread is being laid on the portion of larger diameter. The tension device herein shown comprises two grids or sets of fingers 17 and 18, the fingers of one set bein adapted to play between those of the other set and the thread. or yarn passing between .the 'two'sets of fingers. The fingers 17 are preferably fixcdly sustained by the holder 60. The fingers 18 are secured to the stop 93 which is herein shown as a shaft journaled in the plate 50 and cut away on one side at the point where it engages the shoulder 51. The shaft 93 has extending therefrom an arm 61 to which is connected one end of a spring 20, the other end of the spring 20 being connected to a bar .21 extending across the top of the machine and playing in suitable guides'fifi. There is\ .a similar. tension derice for each of the bobbins, and the. springs 20 for all the tension devices are connected to the 'bar 21. This bar 21 has connected thereto a flexible connection 22, which passes over pulleys 23 and is connected to a small pul'ley' 95 on a shaft 90. Said shaft also has fast thereon a'pulley 97 to which cord 98 is connected, said cord being also connected to one of the arms 13; The pulleys 9:5, 97' and 23 are omitted from Fig. 2 in order to avoid confusion. As the frame 8 rises the cord 98 will be drawn on thereby to turn the pulleys 91'- and 95 and wind up the cord 22 on the latter pulley. This operation draws the bar 21 to the right and thus incrcascs the tension on the springs 20, thereby causing the fingers 18 to bear on the thread with greater force and apply a.

greater friction thereon. 'It will thus be seen that the tension on the thread is greatcst when the frame 8 is in its elevated posh lion with the thread being wound on the portion of small diameter and is least when the frame is in its lowered position with the 13( Rwandan-ems...

' thread being wound on the portion of larger diameter, as shown'in Fig. 1. By means of this construction thethread will be laid uni? formly compact throughout't he thread mass and a much-firmer andbetter thread mass will result.

. I have also provided means for stopping the operation of any spindle-whenever its.

thread'breaks. The flat surface99'on-the 51 has engagement, is situated diametricallyof, the shaft and said shoulder normally eng'tgeS said surface at a point in'ithe" axial e oi the shaft. As a result the pressure ofthe shoulder against said surface 99 -does not have any tendency to turn the-shaft and therefore does not atiect the tension on the thread. If the'thread breaks, however, the

spring and weight of the fingers 18 will 20 cause said shaft 93'to turn, as shown in dot,-

' ted lines Fig. 7-, thus carryin the'flat surface 99-into a sufficiently inc ine'd osition so that the shoulder 51 will slide 0 therefrom whereby the spring 52 will come into play lift the rod 89 and stop the spindle. The embodiment herein shown is the'pre-' ferred'.n}bodinient,-but' it 'will be understood th'at many changesin the'various parts might be made without' departing from theinvention."
