The verticalarm 1 111 5a of the bell crank lever is pivoted at 6a upon a I 55 bracket 6 fixed to the rail C of the machine, and this lever 5a is acted upon by a fiat spring -I,

which is fixed upon a bracket 8, so, as to always tend to force the lever 5a rearwardly.

Pivoted at 8a upon the lever arm 5a is a holding catch 8 which extends horizontally so that its notch 8?) may engage with the front edge of a slotted bracket 9 fixed upon a support 941. ex-

' tending from the upper edge of the rail B in order that the outer end on said catch 8 might abut against the front surface of a bell crank lever I pivoted at Illa so that said lever III may operate said catch 8 and therefore the lever. a which supports the spindle 2 as is hereinafter described.

Pivoted at IIJb on the lever. I0 isa vertically extending rod I which reaches so that its lower end may be pivoted at Ila to a pedal lever I2 that is pivoted at I2a to a bracket 12b by which the pivotal pin I 2a is supported, and said pin -I2a' acts as the fulcrum for the lever I 2 which reaches" ,from it, .in one case to one side of the machine and in the other case to the other side of the ma chine as shown by Fig. 3. V Y,

.The levers I2 are maintained in their normal horizontal positions by springs I3 which are fixed tothe same'bracket i 2b in each case, and by these levers I 2 being adjusted in their normal positions the rods II extending fromthemwill adjust the levers ill also in their normal positions where they do not press upon 'the'ends of the catches 8, but which will operate said catches as is hereinafter describe The yarns .or threads I! which are'to be wound upon thespindles 2 to form the cops I4 of the shapeor formation shown by Fig. 2 are supplied orwithdrawnfrom bobbins I5 which are mounted to revolve freely upon their pegsor fixed spindles I5a, supported by brackets I52) which are fixed on arod [6a supported by a bracket it that 'is-fixed'to the end frame A of themachine.

The bobbins shown by Figs. 1 and 3 are'of a shape having flanges at their outer ends,in which case the winding of the yarn or thread upon the barrel of thebobbin necessitates the ends of the barrels being of a somewhat conical shape in orderto facilitate the'withdrawal of said threads as'is well known,and although We have shown *thebobbins of this shape it is well known that we can withdraw the threads from larger formed bundles of threads mounted on spindles with their outer ends of :taper or conical formation,

somewhat of the character of those of the cops supporting enclosing members 28 and 2%, which members 29 andZGbform a kind of box or enclosing casing forthe parts hereinafter described.

The friction washer i8a isfixed upon the spin dle I9. but the friction washer I8 has a hollow hub formed upon-it to take over the spindle I9 so that the friction washer I8 may loosely slide for a space over said spindle. I9 in order that the arm 2Ia of a lever 2|, which is pivoted at 2Ib,

may press against said hub of the washer I8 to force it against the other washer IBa fixed upon the spindle I9. The end of the lever 2I extends horizontally so that it may be engaged with the arm of a weighted bell crank lever 22 from the other arm 22a of which a weight 22b is suspended; 7

while the lever 22 is pivoted at 22c upon a bracket fixed to the bearing 20. Thus the weight 221) will exercise its influence over the actions of the washer I8 in order to press more firmly upon the thread when such thread is requiredto, have its tensionincreased, or-lessfirmlybysubstituting a lighter weight in order to reduce "said pres sure as circumstances require. Instead of substituting a lighter weight fora heavier weight 222),

the arm 22am the lever may extend horizontally and have notches formed in it along which theordinary adjustable weight may be carried for the said purpose of increasing or decreasing the pressure on the yarn or thread.

During the actions of the machine the thread I I o is taken from the supply I5 and is'carried topass over the spindle I9 and between the friction discs I8 and Illa where it is pressed sufficiently to retardits action; so thatitiis given the desired ten sion' for theloperations. in the ordinary manner.

'From the discs I 8 and fll fia itrpasses over-athreadguide 23 which is fixed ontheibrack'et carried 25 this thread guide 23 it passes .undera-detector 24 upon the framework .of the ,machine, and from (hereinafterdescribed) sothat itmay extend forward through the 'hook of the oscillating thread carrier 25;. This thread carrier reaches from being fixed upon a shaft '25 .so that when oscillating thereon its outerihookedten'd willoarry the thread I'I' in asinuous pathyertically during the rotary motions of the spindle 2 to form the cop I4 as is hereinafter fully/explained. The peripheral surface of thesp'indlc 2 with the coils of yarn wound thereon rests agains'tthe pe'ripheral surfaceof arotary cone'ZI, andthisconeffl 'is arranged'upon its' spindle2lb to rotate freely upon bearings 21a, andby the assistance of antifriction bearings 21c Vthe rotary motionsof the spindle and the coils of yarn-or thread thereon are .suflicient to rotate the cone 21".by frictional contact with it, andthiscone'is arranged to operate as is hereinafter described. The spindle 2Tb forthe cone'2'I extends throughthe bearings '2 is to have a worm 28fixed upon it, and thisworrn meshes with the teeth of a pinion wheelformed in the spindleZS, sothat as theworm28 revolves by meshing with the teeth in the spindle '29, said spindle is rotated and "by'its rotations it carries with it the building car'nBO which is fixed'upon its 'outer end as shown byFigs. 4 to 7.

As-the cam'SEl revolves it operates the outer end the shaft 26 that takes through the bearing 21g as shown "by Figs. fl to 7 so that on the. opposite end of the shaft or spindle '26 the arm 25a of the -'reciprocating thread guide .2i5nis fixed. Conse- 'quently the rotary motions of thespindle '2 trans 'mitted through the cone 2! to the carn'3li, as is hereinbefore described, effects the rising falling movements-of the said thread guide 25.

" In "commencing the winding operations the cone 2? will have the Per phery of its lower edge 21d (see Fig.3) in contact'with adisc or washer 32 made of india rubber, leather or other iris tional material'and fixed upon the upper end-of the sleeve 2b supporting the spindle 2,sai'd sleeve having the whorl o-r driving :pulley I2a fixed at its lower end. Thus rotary motion is transmitted from thesleeve 2b, through the washeri32 to the cone 21. Ihis rotary motion of the 160116) 2-1 continues to be transmitted to it for relatively a v of an arm'3l whichis fixed upon'the outer of 1 considerable period .or until "the coils of yarn on the lower end of the spindle 2 and above the position thereon where the washer 32 is fixed have received sufficient of the coils of said yarn to form the heel of the cop which will therefore only be of the short taper formation shown by Fig. 2. This tapering formation is produced by reason of the relative diameter of the washer 32 to the largest diameter of the periphery of the cone commences to spread over the peripheral surface of the cone 2? from this lower edge 2%, thespced of said cone will increase, since its diameterwill gradually become less where it is incontact with the surface of the building of the cop.

During the building of the coils of yarn on the spindle to form the cop as described, the cone 2? will continue with its periphery in contact with said coils of yarn on the spindle and will gradually rise carrying with it all its bearings Zia as same slide over the'vertical guiding rods 33 and 33a, each of said bearings Z'ig having its respective guiding rod 33a extending from the rail C to the rail D as is shown by Fig. 1.

To assist the raising of the bearings 27g and the cone 2? with the other fittingsmounted upon said bearings Zlg to be easily efiected without too great pressure vertically upon the spindle 2 and its coils of yarn thereon, a cord or other flexible connection 34 has one end fixed to the bearings Z'ig from which it extends over guidingpulleys 34a and which are pivoted upon brackets are fixed upon the rail D in order that the other end of the cord 34 may have .a counterbalancing weight 34g fixed upon it.

As is hereinbeforestated, the rotary motions of the cone 2'! are derived by it from the-coils of yarn forming the cop I4 upon the spindle 2 contacting with it as said coils'of yarn and spindle 2 are being rotated, and during said rotary mo tions of the cone 2'! it transmits rotary motion through its cam to the thread guide 25, in this manner enabling said thread guide to carry the thread from encircling the shoulder of the cop to encircle the nose of said cop, and grad ually, as the diameters of the coils increase, so is the cone 2? caused to rise over its guiding bars 33, lita as is hereinbefore described. These rising actions are carried out until the desired length of cop has been produced, at which time the upper end of the sliding members 2 1g, which travel over the guiding rods 33, 33a, will be in contact with the arm 35 which spans one of said rods'and which is fixed upon a vertical connecting rod 35a, said rod being pivoted at its upper and lower ends 35b and 350 to a three-armed lever 36 and a simple arm 36a respectively, and the said lever 36 and the arm 35a are respectively pivoted at 35?) and 360 to the vertically sliding rod 3! in order that as the rod 35 moves vertically so will it operate the lever 36 as is hereinafter explained. a v

The lower end of the bar 3'! has a slot formed in it for the end of a lever 38 to pass through, as is shown in Fig. 1, portions in front of the first spindle in which are omitted from the drawings to show this lever 38 at the rear thereof, and said lever 38 is retained in its horizontal position shown by Fig. l by resting upon a projection extending laterally from the bracket 9 in order that the vertically sliding rod may normally occupy the position shown by Fig. 2 in which position it also retains the varied articles of devices which are connected to it also intheirnorrnal positions.

. Theraising of the arm 35 operates the lever- 36 assisted by the weight" 36d, so that a notch36f in saidarm will pass over and into the path of motionof a projectiondda on a disc 40 which is fixed upon a horizontal shaft 4i that extends lengthwise' the machine, in order that said projection may engage with the notch 36f and raise the bard! so that itwill lift the horizontal catch 8 out of engagement with the face of thebracket 9 and permit it to be moved rearwardly'as is hereinbefore described under other conditions. Up to now the actions of the fully produced cop have been-to movethe several parts so that by movingthe catch 8 out of engagement, the spindle 2 is brought into the position shown, by broken lines in Fig. 2 where its motion is arrested by reason of its driving band 4 being 'slaokened.

In order to bring about the arresting of the spindle when the detector 24 moves on the breakage or failing of the yarn or thread ll, the detector 2 1 has its arm pivoted at 2419 upon the vertically sliding rod 3?, while an adjustable weight 240, which may be regulated so as-to relieve the weight of the detector or increase the weight of the detector 24 upon the yarn or thread ll, is mounted on the extending end of the lever Eda, another arm 24d extends laterally from the arm 2 5a to take into a notch in the end of a lever 4-2 pivoted at @211 upon the vertical bar 3'! so that its notch 5212 may engage with a projection 63m from a disc 44 which is mounted upon a continuously oscillating shaft 45 extending -'tendant to repair the broken thread in manner well known. I

When the spindle 2 carries the cop Hi from its building position shown in full lines Fig. 2 to its inoperative position shown in broken lines of the same figure, the body 2b of the spindle 2 (which is of larger diameter) comes 'into contact with a fixed brake shoe 2m so that its rotary motion is more quickly arrested. 1 V p When the spindle 2 is withdrawn from contacting with the cone 2? which it operates into the position shown in broken lines where it ohgageswith the brake shoe 2x, the said cone 2! and all the parts carried by same during its verticalmovements are preventedfrom descending by reason of a flat spring 2w, which is fixed by the screw 2y to the base of the bearings 21a, having its free end of a bifurcated form so as to spanand press against the rod 33 as is shown by Fig. 1. This contacting of the spring'with said guiding rod has the effect of forcing all. the bearing 21a laterally, and therefore said bearing 21a is held from descending by its frictional contact with the guiding rods 33. On the other hand, on account of said spring 2wbeing. of a comparatively flexible light character, when the bearings upon which it is mounted are rising, their rising movements are freely permitted, since the spring derive their oscillatory motions from a crank pin which is fixed in the face of a wheel Ella rotated by gearing with the wheel 501). This wheel 50b is fixed to the arms of the pulley 5| so that the rotary motions transmitted to said pulley'by the driving belt 5la taking over a driving pulley v5Ib that is fixed upon the shaft 52a upon which the driving pulley 52 is fixed, will operate the crank pin 59 as desired, and these motions are derived from the main shaft-53 of the machine.

operating a belt 53awhich rotates the pulley 52.

The reciprocating motions of the crank pin 50 oscillate the lever 54 which. is fixed upon the shaft 4|, so that said shaft 4| may oscillatea lever arm 55, and this arm 55, by the rod 55a,-wi1l reciprocate an arm 55b that is fixed upon the shaft 45. Thusreciprocatory motion is given-to the two shafts 4i and 45 upon which the disc carrying aprojection 40a. and a disc .44 carrying a notch 43a are fixed. Motion is'securedfor said discs and their projections to raise the bar 31 in the manner and under the conditions, hereinbefore explained.

7 It may be observed that the shafts 4| and are mounted on one side of the end frame A to operate the devices in connectionwiththe spindles 2 on said side of the frame. Similar shafts on the opposite side of the frame, are employed for operating in the identical manner and for identical purposes, and the motions are transmitted to these oscillating shafts from'the oscillating shaft 1 4-l'by an arm 51 and itsconnecting rod 51a being coupled to a similar arm and similar shafts on the opposite side of the machine. In order to prevent the friction discs l8 and l8a being worn by remaining constantly in one position, so that the threads or yarns passing between them are rubbing in one position upon their'surfaces, we arrange said discs to be ro.

tat'ed by means ofthe. ratchet wheel l9a which is fixed upon thespindle 19 upon which the discs I8 and Mia are carried. This ratchet wheel I9a is, intermittently reciprocated by a pawl which extends horizontally to be pivotally connected to a disc 6| fixed upon the oscillating shaft 45 d so that as said oscillating shaft is oscillated under the conditions hereinbefore described, the reciprocating motions will give a step by step slowly moving action to the wheel I9a and'therefore to the discs mounted thereon, and by arranging the horizontal part of the pawl 60 to overhang a projection from onearm of a bell crank lever 62 which is pivoted at'62a, when said arm 62 of the lever is operated by the connecting rod 63 pivoted at 63a to the horizontal armu5 of the leverj5a, said arm 62 of the bell crank lever will raise the pawl 60 out of engagement with said wheel as is shown in broken lines Fig.2. Thus the'motions of the discs will be arrested simultaneously with the arrestingof the motions of the spindle and its dislodgment from its operating position to the position shown in broken lines Such being the nature 0 of the same figure. our said invention, what we claim is:-
