- a toothed quadrant 25 Secured to the shaft i9 is a toothed quadrant 25 the toothed edge of which is located between the fianges I8' and is in mesh with the pinion I8.
- an arm 25.5 carrying a bowl 2'! (see Fig. 2) which is engaged between cam edges 28, one only of which is shewn and which cam is driven by the automaton, such cam providing oscillatory movement in both directions of the shaft I9 and through the quadrant 25 and pinion I8 amplified oscillatory movement of the sleeve I2.
- a pair of collars 2S spaced slightly apart and adapted to be engaged by a peg 3B on a lever SI which is pivoted by one end to a bracket 32 attached to the end bracket 2i.
- the other end of the lever is forked and is engaged with a stud 33 (see Figs. 1 and 2) on the lower part of tbe tailstock 23.
- the arm I3 has an ejector 34 of T-shape (see also Fig. 1), the tail of which is forked, the ends of the fork being bent round to clip over a pivot pin 35 about which the ejector is free to pivot.

- the cam faces 23 now operate to turn the arm i3 lowering the quill into a waiting position in which the ejector 34 is about to engage the blocks 31 for ejection and while the quill is held in this waiting position the automaton draws the collector fork 39 over the top of the quill so that its hooked forked ends engage the thread and draw it towards the winding spindle, such thread (not shewn) being still in vtension between the'quill and a yarn guide not shewn.
- the thread therefore assumes a substantially vertical and predetermined position 4 between the hooks and is brought by them towards the spindle head Iii' until it engages the iiange H32 for the purpose of enabling the thread to be brought into position for gripping between the head I8 and the flange H12 as described in detail in co-pending application Serial No. 99,481.
- the automaton After a new tube or core has been brought into position between the tip end 23 and the winding spindle head I3', (means not shown) the automaton now pulls the rod 24 closing the tip end 23' onto the new core and this movement of the tailstock also causes return sliding movement of the gripper arm I3 but without performing any function. Thread cutting mechanism is then brought into action and the automaton also returns the collector fork to its original position and the means not shewn which brought the new core to the winding station.
- the cam faces 28 turn the sleeve l2 lowering the arm I3 for the ejection of the full quill which is caused by the engagement of the ejector 34 with the blocks 3? arresting its movement while the arm I3 is lowered further to its normal, or idle position.
- the ejected quill falls into a basket or other suitable receptacle.

24, of flat cross section, connected to the tail stock 23. Secured to the shaft i9 is a toothed quadrant 25 the toothed edge of which is located between the fianges I8' and is in mesh with the pinion I8. On the end of the shaft IS adjacent to the headstock is fixed an arm 25.5 carrying a bowl 2'! (see Fig. 2) which is engaged between cam edges 28, one only of which is shewn and which cam is driven by the automaton, such cam providing oscillatory movement in both directions of the shaft I9 and through the quadrant 25 and pinion I8 amplified oscillatory movement of the sleeve I2. Near the other end of the shaft l s are fixed a pair of collars 2S spaced slightly apart and adapted to be engaged by a peg 3B on a lever SI which is pivoted by one end to a bracket 32 attached to the end bracket 2i. The other end of the lever is forked and is engaged with a stud 33 (see Figs. 1 and 2) on the lower part of tbe tailstock 23.
Referring to Fig. 3, it will be seen that the arm I3 has an ejector 34 of T-shape (see also Fig. 1), the tail of which is forked, the ends of the fork being bent round to clip over a pivot pin 35 about which the ejector is free to pivot. In the head I3 of the arm is an adjustable screw stop 3G the end of which forms stop to position the ejector so that the head of the ejector 34 and the two rollers IB provide triangulated holding points for the quill Il. On the rod IS are fixed a pair of blocks 37, which are in register with the arm I3, so that, as described later, such arm can move between them and the ejector can be engaged with the ends of the blocks for ejection of the quill.
On the shaft 22 is slidably mounted a slide 36 to which is attached a collector fork 38 the slide having a key 45 sliding in a key-way 4I in the shaft. The slide 38 is adapted to be moved along the rod by a link 42 connected to the automaton.
In operation, assume a quill is in the winding station and winding has just been stopped by any suitable measuring mechanism which at the same time starts the automaton, such mechanism being well known in automatic winders. The cam faces 2B commence to rotate and turn the shaft I9 which through the quadrant 2t and pinion i8 causes the arm i3 to rise pushing the rollers I6 over the quill I1 and so that the head of the ejector 34 rests against the underside of the quill, giving a triangulated Contact with the quill while the latter is still between the centres of the winding head. While the arm I3 is held in this position, the tailstock 23 is pushed back by the automaton through the push rod 24 which movement also, through the lever 3l, peg 30 and collars 29 pulls back the rod i9 through about half the distance of the movement of the tailstcck 23. The rod I9 through the quardant 25 and iianges I8 moves the sleeve I2 with its arm I3 along the rod I I through such half distance. Thus the tip end 23 is withdrawn from the quill I'I' and the quill is withdrawn from the spindle head I0' the quill being still held substantially in axial alignment with the centres of the winding head. The cam faces 23 now operate to turn the arm i3 lowering the quill into a waiting position in which the ejector 34 is about to engage the blocks 31 for ejection and while the quill is held in this waiting position the automaton draws the collector fork 39 over the top of the quill so that its hooked forked ends engage the thread and draw it towards the winding spindle, such thread (not shewn) being still in vtension between the'quill and a yarn guide not shewn. The thread therefore assumes a substantially vertical and predetermined position 4 between the hooks and is brought by them towards the spindle head Iii' until it engages the iiange H32 for the purpose of enabling the thread to be brought into position for gripping between the head I8 and the flange H12 as described in detail in co-pending application Serial No. 99,481.
After a new tube or core has been brought into position between the tip end 23 and the winding spindle head I3', (means not shown) the automaton now pulls the rod 24 closing the tip end 23' onto the new core and this movement of the tailstock also causes return sliding movement of the gripper arm I3 but without performing any function. Thread cutting mechanism is then brought into action and the automaton also returns the collector fork to its original position and the means not shewn which brought the new core to the winding station.
Finally, the cam faces 28 turn the sleeve l2 lowering the arm I3 for the ejection of the full quill which is caused by the engagement of the ejector 34 with the blocks 3? arresting its movement while the arm I3 is lowered further to its normal, or idle position. The ejected quill falls into a basket or other suitable receptacle.
.As shewn in Fig, 5 the winding spindle It the end of which is shewn in chain line is drilled to receive alternative sizes and shapes of adaptor heads l0 according to the tube to be used. The present device is therefore shewn as an adaptor head and consists of a spindle portion t3 with a screw-threaded extension 44 and spigot tail 45 adapted for fixing in location in the end of the spindle. The spindle portion 43 has a flange i G2 and is formed with a cylindrical axial end socket 0,5. Slidably located in such end socket is a plunger IS' having a tail 4l located in the socket, a cross pin d8 limiting its axial movement and constraining it to rotate with the spindle end 43. In the socket is a light compression spring de. The plunger i0 has a conical portion 59 the base of which is formed with a peripheral rim E0 adapted to lie against the end face of the iiange 592, so that such adjacent faces form a yarnreceiving and clamping means. At the outer end, the plunger I is formed with a small extension or centre 5I of a size suitable to t into and locate the end of the quill tube 52, behind which extension is a groove for a friction ring 53.
The tailstock is of known construction and includes a free running spindle 54 carried in a bush 55 slidably mounted in a housing 56 with limited cushion spring axial movement, (the spring not being shewn) the housing 58 being adjustable in the tailstock 23 which latter is adapted to be mechanically advanced and withdrawn by the automaton as already described and the cushion spring being partially compressed when a quill tube is in position. The spindle has an adaptor head or tip end 2.3' which is changeable for different sizes and shapes of tube.
In operation, as soon as the tailstock is withdrawn hy the automaton, the full quill is released and the plunger IB is urged forward by its spring t9 to open the base of the cone 58 from the nange H32. The parts are in this position ready to receive the yarn between them when it is brought against the ilange by the hooked collector arm S9.
