This bell-crank lever IOI, I02 carries a cutting -.element f, shown by way of example as a serrated knife I03 or as astraight cutting edge I04. Also a guide plate I06 is fixed on the arm I02 of the bellcrank lever.

Then, when 1 the revolving continues, the tube holder closes and-clampsthe tube, as the projection II slips off the curved bar 13. The tube'is thus carried ding bobbins S'are mounted'on the free 62, which swing about;

For-simplifying t j m ing of the-tubes reyolving pages are as the tube leaves the magazine. The cross winding fr'ame as erates in the following :nianner': It is assumed along, the bottom plate IIl'l yielding temporarily that four supplybobhihs-K are skewered on the magazine table 2I.fand 'that the yarn has {been-threaded through ,tensioner T. and the slot ..i of' driving drum. 6 I-tof the lower tube L on the winding bobbin holdertgalso, that the shafts I and are ifotatinghand the, tubeLL is therefore being.v driven by the drum 6l and. the yarn andheld lnxclosed position by atspring 12; eta-# -winding .upon it. ,The leading ends 'of'the bobbins Ks and-K2 are knotted respectively, to the @traili-n'g ends of the-bobbins Kz' andfKi. The

. leadingfenid'gof; the fbobbin' 'Kt and the trailing "end offthe b bbin Kaare placed in'th'e correspondi'ngslbt and clamp 24. When the bobbin described op-' K1 is exhausted, the thread jumps across to' the bobbin K2 and the winding'proceeds. vAt the same time the feeler 32 is rocked by. its spring and closes'the switch32a; This excites the electromagnet 3| and-the armature 30 moves in.

the direction of the arrow, engaging the clutch 20. The shaft 26 beginsto rotate, moving the peg of bobbin K1 through the stripper 25 and stripping off the tube H of this bobbin, which; falls onto the conveyor I I. The reserve bobbin m, meanwhile, moves toward-the running position and the bobbins K3 and K4 advance accordingly. When the plate -2I has completed a quarter revolution the bobbin K2 has moved against the feeler'32 and opened the switch 32a, disengaging'the clutch 20 and stopping the rotation of shaft 26.

Meanwhile, the cam disk 4I has executed a quarter revolution, during which the, ar m 43 has rocked the post 44 and the knotting device the cam 90 and link I00, moves toward'the position shown in dash linesat the right side of Fig. 1. -Whenthe revolving page has, moved through approximately a'qu arter revolution, the lug 1 Iv of the gripper holdingthe completed bobbin, camm'ed over by cam. I3,, ,ha's opened the gripper to the point where the, bobbin can escape and roll down the guide I "to, the trough l4 and thence to the a conveyor I2, Thetrailing yarn from the wound 'bobbin caught by the knife I03; or I04, and severed, but is-flrstbrought against the new tube L whichihas .beenlmoved into running position by the du'arter irevolution the yarn and 45 mounted on it to the right, until the position- 'shown in dash lines in Fig. 1 is reached. During this movement, the tail of dog rocks the stop 52 to the right and passes under it.

Thereupon the roller 42 drops oil? the high part of the cam 4| and the knotting device rocks toward the left, into engagement with the yarn:

ends of bobbins K1 and K4, which at this moment have arrived in the position occupied by the yarn, ends of bobbins & and K3 in Fig. 2. As the knotter rocks tothe left the tail SI ofdog so strikes the stop :52 and the dog is' lifted out of engagement with the sliding bolt 46b, which is thrust into the socket 48a of sprocket 48' by its spring 400. The bush 46 of the knotter is thereby turned through one revolution, which is suificient "to cause the knotter bills to complete the knot. of the knotter bills the dog 50, which has resumed its original position, cams thesliding bolt 46b out of the socket 46a and stops the knotter. The magazine is now in the same condition as At the. close of the revolution of the revolving cage. I, Iff't'h'ef yarn is stiff o:

"winding bobbins so, initiated.- If the tube holders are not. inv a revolving device, but, as usual, on the front ends of frame 62,- a corresponding locking device and so forth must be provided, which preventsan empty tube from sliding out beforetheholder 'of the completed cross. wound bobbin 11s "liberated, or a feedingdevice which moves 12 8. magazine with its lowermostfitube 'betweenfthe. ,.opened holder at the start, except that the bobbins have moved 0 up one step and one of the pegs 22 .is ready to receive a new bobbin. The mounting of new bobbins on the pegs can be allowed to await the arrival of the first empty peg in the position of the bobbin K3 in Fig. 2. In mounting the bobbin on the peg the operative brings together the trailing end of the precedingbobbin with the leading end of the bobbin just mounted and places them in the intermediate slot 23 and clamp 24.

The bobbin S continues to accumulate yarn until, a predetermined number of cops K having been unwound, the cam 94 has released lever 92, 93 and arm 8| has been raised by the link 9| to withdraw the end of the arm 83 from the coupling bolt 'I'Ia. When this occurs, the coupling bolt engages the socket 840. of gear 84 and the bush I'I begins to rotate. Through the chain and sprock'et connection I4, I5, I6, the bobbin cage begins to revolve. At the first movement of the bobbin cage the lug II of the upwardly directed tube gripper 69, I0 moves oif the cam I3 and the spring 12 throws the gripper against the tube end, the grippers 61 and I0 being at this moment positioned exactly at the ends of the bottom tube in the magazine I06. Upon further movement of the revolving cage the gripped tube is pulled out of the magazine, flap I0'I yielding to permit its escape and then closing to catch the next tube above. The rotation of the revolving cage moves the full bobbin S upward, while the knife I03, or I04, actuated by p and hits it again after the tu holderhas'been I closed What we claim a's our invention and desire to secure by Letters Patent or the United States is:
