Application filed June 29.1927, Serial No.

My invention relates to doffing apparatus for spinning, doubling, twist ng and like machines of the type known as fiyer frames and my present'invention consists in the employment of, deviceswhich I arrange to be actuated by the lifter shaft to secure-the removal ofthe full bobbins from operating position secures the placingof the emptybobbins upon the spindles, the retraction of the empty bobbin holders to allow the raising of the lifter plate and the final advance of the empty bobbin holders intotheir normal positions during the spinning operations. In connection with the above devices in' accordance with my invention 1 make use of means for operating the drag cords, devices for adjusting the flyers, cam

operated bifurcations for-clearing or remov- .ing any coils of threads that may encircle the spindles, a slotted rod for receiving the threads so that the attendant may cut or sever said threads by drawing a knife alone;

same, an adjustable receptacle forthe full bobbins and couplingandlbrake devices for permittingthespindles to rotate under conditionswhich are hereinafterexplained.

In order that my said invention may be readily understood I have hereunto append-' ed sheets of drawings illustrative thereof to which by figures and letters, reference is made in the following description Fig. 1 iwa front elevation of'sufiicient of a flyer spinning frame'to show the application thereto of my improved parts.

A. A indicate the two end frames ofthe machine.

The devices known as the. lifter mechanism? whichI make use of are of the type wherein cam mechanism. causes a horizon tal shaft to oscillate so that by chains taking over chain pulleys fixed thereon, the ris 3 extending beneath them awhile their di'iv- Ital f ing pulleys or wharles 4 are at their upper arranged to take through the lifter plate in well known manner.

The lifterplate 5 is arranged to carry out its'vertically reciprocating motions to elfect the building of the coils of yarns on the bobbins in known manner and by well known cam operating devices which actuate the chain (j-that encircles the pulley 7. This pulley 7 is mounted so that it may be detached from the shaft 8 during the doiling operations, while its coupling to said shaft iseifected for carrying-out the usual spinning. process, by devices hereinafter described. v

Fixed upon the shaft 8 and adjoining the chain guiding pulley 7, is a spur wheel 9 which mesheswith a pinion 10 and this pinion is fixed upon the hub of a hand wheel 11 so that when the operative actuates said hand wheel, 11 he may actuate the wheel9.

To couple the pulley 7 to the wheel 9 I employ a clutch bolt 12 which I mount to slide upon one or other of the arms of thewheel 9 so that bythe handle devices 12 said bolt 12 may be made to engage with the-pulley 7 in order to couple same to the wheel .9 to enable said wheel to transmit motion from the pulley 7 to the shaft 8 during the spinning of the yarn and the winding of same in coils upon the bobbins in well known manner.-

The hand wheel 11 and its pinion 10 are mounted upon a stud 11 supported by appropriate bearings fixed to the end frame A.

The lifter plate 5 is connected to and is operated by the usual chain'devices which are made to encircle chain pulleys fixed uponthe shaft- 8 in several positions throughout the length of said shaft 8 in order to meet the requirements of a longer or shorter lifter plate 5 according to the number of spindles in the machine, as is well understood. I

. The drag cords 14, are connected at the rearof the spindles 3, tea sliding rod 14* and to the front of the'spindles to another notched sliding rod 14"(see'Figs. 2 and 3) so that during thespinning operations their weights 14; may cause said drag cords 14 to press against the edges of-the lower flange's of the bobbins 13 in well known manner. i 3 l As is well known, the drag on the bobbins 13 during, the building operations has to be increased andto effect this increase the drag cords are gradually moved to press more firmly against the flanges of the bobbins as thefcoils of yarn thereon increase in diameter. To. secure this increase of drag action I employ the well known ratchet wheel and worm devices (not shown in. the drawings) whiclrmove the two sliding bars 14:;and 14" fromright to left in order to cause the drag cords 14; to more firmly press upon the flanges of the bobbin 13 to meet the increased leverage which the threads exercise over the bobbins upon which they have been wound as is well understood.

When the coils of yarns are being wound upon'lhe bobbins 13 to fill said bobbins in known manner, the lifter plate 5 is raised and lowered or reciprocated in its vertical path through its usual space to control the guiding of the yarns upon the bobbins from the lower to the upper ends of same throughout the spinning operations until the bobbins are filled, and during said operations the lifter plate 5'is actuated by its cam mechanism in the ordinary and usual manner during which no motion is transmitted to any other part which I employ for the doll ing process hereinafter described.

In order to carry out said dolfing process according to my presentv invention I make use of the devices above explained to dis engage the mechanism which actuates the lifter plate during the spinning proccss,lo allow said lifter plate to be separately operated to effect the dofiingr.

.1As means for performing these dolling actions, I fix cams upon the shaft 8 for at footing the further and necessary movements. That is to say, to secure the levelling; or adjusting oi the flyers 2 I mount a cam 16 (shown by Figs. 5, 12 and 18 and hereinafter more fully described) upon the shaft 8 and this cam 16 is arranged, by the lever-116", to move a bar 16 which is carried upon the end of the lever 16 that is supported by bearings 16 fixed to the framework of the machine. This bar 16" extends longitudinally the length of the machine to be sup ported by other lever arms (similar to 16) also mounted upon fixtures carried by the framework of the machine. thus the bar '16" may be moved longitudinally by its cam 16 and will be supported by the lovers '16 throughout its longitudinal movement. i a On the bar 16" are pivoted two or more levers 16. according to the length of the machine, and the rear ends of the levers 16 are actuated by a spring 16 which keeps or tends to keep said lever-.16 in their advanced positions. The levers 16? are sullicient in number to support another bar 16 which ex tends the full length of the machine in order that the inclinesaon the front edge of said bar 16- may come in contact with the legs of the fiyers 2 somewhat as is shown by Fig.

5, by which means when the cam 16 is 1'0 tated by the shaft 8 it will actuate thewhole series of flyers 2 to bring their legsinto or approximately into the same vertical plane.

Also fixed on the shaft 8 is another cam 17 (of a formation hereinafter described) and this cam 17 actuates the lever 17 (which is pivoted upon the framework of the machine) so that said lever 17, may, by the rod Ill) 1'7 actuate a lever 17 which is fixed upon a shaft 17. y

'This shaft 17 is supported by the framework of the machine and has a series of arms 17 fixed uponflit the number of said arms being suflicient to carryor support a longitudinal shaft 17 whiclris swivelled on the outer ends of same.

Upon this swivelling shaft 17 (which is preferably square in cross section) are mounted bifurcated members 17% (corresponding in number with that of the spindles 3) which will when being moved, span the spindles 3 so as to wipe or carry away the coils of threads extending from the legs of the flyers and encircling said spindles 3 after the'full bobbins have descended beyond the lower endsyof same as is well known. l a i V In an appropriate position upon this square shaft 17 isfixed a lever 17 (see Fig. 10) so that a stud 17 extending laterally therefrom may take beneath a cam piece 17 fixed upon a bracket 17 which is secured to the frame-work of the machine. Thus as the cam 17 isrotated (as ishereinbefore described),yand as it is carried by the shaft 8, the lever 17 will cause the levers 17 and and said shaftl't' to oscillate. This oscillation of theshaft li' by the actions of the-cam 17 brings the arms 17 so that the shaft 17 carrying the bifurcated member 17 will cause these latter to span the spindles 3 as is shown by-Fig. 9. The motion transmitted to the shaft l in this forward direction is such as to cause said shaft to carry its lever 17 'in order that the stud 17 will pass the lower end of the cam piece 17? at the point 6 (Fig. 10). 'Here it will encounter the hinged piece 17 which is free reaching the point where thehinged plate 17 will engage with the stud 17 k the actions of the cam 17 upon the stud 17? are reversed during "the reverse movement of the shaft 8 as is hereinafter described. and at this time the shaft 17 will be tilted so that the bifurcations 17 will-ascend to their positions shown by Fig. 14Ibypassing through a path which lies clear of the lifter plate 5, the spin- .dles and any bobbinsthat may be mounted thereon. This is effected by the stud 17 following thecontour of the cam piece 17* until its normal position (as shown by Fig. 10) is reached. i

Fixed upon the same shaft 8 is another cam 18 (formed as hereinafter described) which operates the lever 18" and this lever 18 is connected by a rod 18 to a lever 18 fixed upon a longitudinal shaft 18. This shaft 18 extends lengthwise the machine and has fixed upon it the arms 18 At the upper ends of these arms 18 is fixed a longitudinal rail 18 and upon this longitudinal rail are fixed a series of bobbin engaging members 18 These members 18 are for engaging theupper flanges of the bobbins 13 as shown by Fig. 1% as well as acting as displacers for the full bobbins.

To enable the member 18 to engage with the bobbins 18 slots 0 (see Fig. 4:) are formed laterally in said members 18 to span the barrel parts of the bobbins 13 and yet to carry the upwardly projecting flanges (Z which extend from the engaging members 18 to receive and overhang the flanges of the bobbin, also shown'by Fig. 1-4.. v i

The cam 18 is arranged to have a part of its surface to occupy a normal position shown'by Fig. during the spinning operations and in said normal position the engaging members 18 may have placed upon them the empty bobbins 13 as is shown by Figs. 14: and 15 while whenthe cam 18 is rotated by the shaft 8 said members 18 may be moved from the said front position .15 where all the bobbins will be held clear of the spindles o and lifter plate 5. This. extension 18 from the rail v18 ,to the rear of the barrels of the bobbins 13 are employed so that they may support the bobbins in a lateral. directionand keep them in proper position, as is shown in broken lines Fig. 15 to enable them to clear or push away the full bobbins as is hereinafter described.

The lifter plate 5 is actuated by the known devices hereinbefore explained and is provided with known means whereby the longitudinal bars to which the drag cords 14 aresecured are caused to advance as is set forth. During their advancing move: ments they will earrywith them the bracket 19. at the lowerendof which is pivoted a small runner 19 so that said runner may groove in afixed cam plate or bowl or runner .19 moving within the broader grooved part 19 of thecam plate 19 'However, when the doiiing operations are to commence said runner or bowl 19 on descending with the lifterplate 5 will come in, contact with the inclined edge d ofthe flanges of the lower end of the bobbins and when the attendant, readjusts the lifter plate into its working position as is shown by Fig. 1 thebowl 19, will, by coming in con tact with the inclined part cl of the cam plate 19", have caused the bars 14: and 144 to move from their position where the cords were clear of the bobbins so as to bring same bars and their cords into the desired position against the edges of the bobbins on reaching the position shown by Fig. 1 in which case all of the cords are readjusted into position so as to place the least amount p of drag required upon the bobbins 13 at the commencement of the spinning operation, the increasing of said drag being effected by the devices hereinbefore described.

lVhile the shaft- 8 is being oscillated to carry out the vertical reeiprocationsof the lifter plate 5 during the process of spin ning, the cam 16 is not moved suiliciently far to bring its cam surface to act upon the lever lti hence during said process of spinnin said lever 16 and all the parts it moves or operates, are stationary. In like manner and during the same actions the operating grooves in the cams 17 and 1S permit these latter to be moved by the shaft 8 without bringing their cam surfaces into action, thus. at thistime the devices they actuate remain in their normalinoperative positions.

The operations of the several parts are as follows After the bobbins 13 have been filled with the coils of yarn as is shown by Figs. 1a and 15, and at the same time the series of empty bobbins 13 have been placed by the attendant upon their engaging members 18", the attendant will disengage the coupling bolt 12 by actuating the handle 12 so as to free the pulley 7 from its connections with the shaft 8. He may then actuate the hand wheel 11 and by the pinion l0 and wheel 9, cause the shaft to revolve in order to lower the lifter plateb beyond the position where the upper ends of the full bobbins 13 would be clear of the lower endsof the flyers as is shown by Figs. 12 and 13. After this position is, reached by continuing the motions of the hand wheel 11 the lifter plate 5 will continue to descend and simultaneously with the descending of this lifter plate 5 the cam 16 will now have brought the flyer operating bar '16 into its position shown by Fig. 5 so that all the flyers are adjusted in the desired position.

Shortly after the adjusting of the flyers in the position described, the cam. 17 will have operated theshaft 17 so that the bifurcations 17 will engage with the spindles 3 by spanning same; thus ou descending they will remove any coils of yarn that may be encircling said spindles 3, and the continued motion of the bifurcations 17 will carry said yarns beyond the lower ends of the spindles. Simultaneously with the actions of the cam 16 to bring the legs of the flyers into alignment, and commencing at about the same time, thecaln 18 will actuate the bobbin engaging members 18" and will remove same from their positions shown in full lines Figs. 14; and 15 to the rear position shown in broken lines of Fig. 15 so that said bobbins 13 are moved clearv of the lifter plate 5 during its descent. After the lifter plate 5 has descended with its full bobbins past where the empty bobbins are shown in broken lines Fig. 15 down to its lowest position, the cam 18 will, bycontinuing in motion cause the members 18 to advance from their rear position shown in broken lines Fig. 15 to the position shown in full lines by said Fig. 15, there they will have encountered the full bobbins and, will have pushed same off the lifter plate 5 as is shown in broken lines Fig. 15 in order that they will descend into a trough or receptacle 20 which extends the length of the machine.

' \Vhen the empty bobbins 13 have reached this last named position with all the full bobbins cleared away from the lifter plate, the attendant will reverse the direction of 1no- ,tion of the hand wheel 11 and will thereby reverse the niotionsof the shaft 8 in order to carry the several cams back to the normal positions which they occupy during the spinning operations, and in doing this the lifter plate will move from its position shown in broken lines by Figs. 14 and 15 to raise the empty bobbins 13 onto the lower ends of the spindles 3 and so soon as said bobbins 13 have been moved for a sufiicient space over the ends of the spindles 3, the cam 18 will again cause the bobbin engaging members 18* to move to the rear of the lifter plate 5 in order to permit said lifter plate to rise into its operating position above said engaging members 18 When the lifter plate 5 has thus ascended above the members 18 these latter will re turn to their normal forward positions where again the bifurcations may (afterwards and after tlie'spinning process has been commenced) receive their supply of empty bobbins as will be understood. On the lifter plate 5 being further raised, by the movement of the hand wheel 11 carrying the wheel 9 into position for the engaging bolt 12to en gage with the pulley 7, all the dofiing operas tions will have been completed and every part of the dotting mechanism will have been rc adjusted in its respective position ready for the spinning operations to be re-started.

The machine is then put into motion until a few coils of yarn are wound upon the newly supplied empty bobbins, when the machine is again arrested, all the loose or extending yarns from the bobbins on the spindles 3 to those in the receptacle 20 (see Fig.

, knife along the groove l3) will extend over a longitudinally grooved bar .21 acrossv the groove 21 in which are made other grooves 21 in number to the spindles in and therefore to the threads therefrom.

the machine that extend Before starting the machine into further of said brake devices and coupling means' are in suchtpositions as to retard or hinder the flyers and their spindles from revolving so that difficulty might arise when the flyer adjusting mechanism was brought into use. To. avoid this I make use of a rod (see Figs. 10,and11).which I fix upon the ends of levers 31 so th-atsaid rods 30 mayextend above the operating handle devices 32 which actuate the brake and coupling mechanism described. The lever 31 at the end of the machine shown is pivoted at 31 and is coupled by a rod 33 to a lever 34 pivoted at 35 so that a bevel wheel or quadrant 36 fixed to said lever 34 may engage with another bevel wheel '37 that is fixed to a horizontal lever 38. This lever 33 is connected to the starting rod 39tl at extends lengthwise thezmachine so that immediately the attendant operates the starting handle 40 to stop the machine prior to dotting, the shaft 40 will oscillate and cause the lever 41 also to oscillate. To this lever 41 is connected the rod 39 hence the oscillating of the lever 41 will cause said rod 39 to be moved longitudinally to operate the lever 38 so as to depressthe longitudinal rod 30 thereby relieving all the handle devices which operate the clutches and brake mechanismso that the flyers 2 and their spindles 3 may then be rotated freely. 1

. The receptacle 20, which receives the full bobbins when same are forced forward to fall from the lifter plate is of the formation shown by Fig. 13, and isarranged to be supported by. extend from the framework of the machine; From the rear lowerfedge of this receptacle 20 a projection 43 extends which carries a bowl 44.

This .bowltakes into a guiding slot 45 so thatas. the. extending end of a hand actuated lever (not shown by the drawings) movesthe rod 46 which is coupled to it. and to abracket 47 on the receptacle 20, in arearwa'rd direction, saidreceptacle 20 will be, moved from theposition shown in full lines Fig. 13 (Where it will receive the fullbobbins) into the position shown in broken lines of the same figure and in this (see Fig, 12) equal yarns are cut and the ma.

a seriesof brackets 42which position may be used as a platform for the attendant. to step upon when reaching articles from the upper parts of the machine.

Such being a the nature and object of my saidinvention what I claim is::-'
