Abstract: 998,100. Reeling yarn. CROON & LUCKE G.m.b.H. April 26, 1962 [Feb. 3, 1962], No. 16065/62. Heading D1J. A machine for reeling hanks 14, Fig. 2, on a revolving cage 6, includes a main electric motor (not shown) for driving the cage 6, and an auxiliary motor 94 for sliding one bearing end 3 for the cage axially away from the cage shaft 7, Fig. 5, so that the hanks can be removed from the freed end of the cage. A full winding cycle is as follows. When the hanks 14 are fully wound the main electric motor is stopped and further rotation of the shaft 7 is prevented by manually displacing a lever 60, Fig. 8, such that a pin 61 on the lever engages in a notch in a disc 58 rigid with the shaft 7. This movement of the lever 60 also operates an electric circuit in a manner ensuring that the supply to the main electric motor is cut off. Fig. 2a shows the reel cage when it has been automatically reduced in diameter by a first . amount so that the individual hanks hang without tension on the cage and can be tied off to form skeins. The cage is then caused to reduce in diameter by a further amount and the skeins 14 are manually moved to one side Fig. 4. A cage support arm 15 is then swung upwardly so that rollers 16 thereon engage the underside of the shaft 7 to support the cage 6 whilst the bearing end 3 is displaced, Fig. 5, to permit removal of the skeins 14. The diameter of the cage 6 is varied by means of a reversible motor 50, Fig. 1, driving a chain wheel 49. When the motor 50 is energized, on completion of the hanks, a coupling solenoid 56 is energized to move a lever 54 to the right to couple the wheel 49 through a clutch to screw means in the shaft 7, the resulting rotation of which causes a decrease of inclination of spokes 9 linked with the slats 8 of the reel cage 6. A time relay (not shown) switches off the motor 50 when the cage diameter required for tying-off the hanks Fig. 2a has been reached. When the tying-off has been performed, the motor 50 and solenoid 56 are re-energized and the inclination of the slats 8 is further reduced until stopped again by the time relay to set the diameter of the cage to that described with reference to Fig. 4 The means for raising and lowering the arm 15 about its pivot centre is interconnected with the means for displacing the bearing end 3 such that the arm 15 is always raised before the bearing end 3 is moved away from the cage and such that the bearing end 3 is always brought into engagement with the cage before the arm 15 is lowered. This sequence of movements of the arm 15 and bearing end 3 is controlled by a threaded spindle 90, Fig. 14, connected to a reversible motor. The spindle 90 carries a movable screw threaded block 96 having a recess 96a in its upper face, the edges of said upper face being extended at its ends by tubular members 97. As the block 96 is moved from a right hand position to the position shown in Fig. 14 it carries with it a pivot 99 resting in the groove 96a so as to carry the pivot 99 to the left, the pivot being guided by two slots 100 (100<SP>1</SP>) Fig. 12 and serving to actuate the arm 15. The slots 100 (100<SP>1</SP>) are inclined upwardly at their left hand end so that as the pivot 99 reaches this inclined portion of the slots 100 (100<SP>1</SP>) it is forced upwardly out of the groove 96a to rest on the upper surface of the right hand tubular member 97 and further movement of the pin 99 to the left is thus prevented. During this period a second pin 102, operating the bearing end 3, rests on the upper face of the left hand tubular member 97 but as the block 96 passes thereunder the pin 102 drops down into the groove 96a to be carried by the block 96 to the left, the pin 102 being guided by slots 101 (101<SP>1</SP>) Fig. 12 that are inclined at their right hand ends. Similarly, when the rotation of the spindle 90 is reversed, the pin 102 is first moved to its extreme right hand setting by the block 96 whilst the pin 99 rests on the right hand tubular member 97, and then the pin 99 is moved to its extreme right hand position whilst the pin 102 rests on the left hand tubular member 97. The movement of the pins 99,102 into the groove 96a in assisted by a rocking device 103 containing a lubricant, the device 103 including wicks 114,115 dipping into the lubricant and leading to outlets 112,113 for the lubricant.
