Abstract: 398.660. Creel - ap - paratus for yarn-winding frames and devices for supplying bobbins thereto. REINERS, W., 48, Rheydterstrasse, Gladbach, Munich, Germany. Oct. 21, 1932, No. 29509. Convention date, Nov. 25, 1931. [Classes 120 (ii) and 120 (iii).] In a yarn-winding frame having a mechanical conveyer whereby supply bobbins are conveyed to the creel spindle units in combination with mechanism for automatically stripping the empty bobbin tubes from their spindles or pegs, the creel pegs 24, Figs. 1, 2 and 4, for the cop tubes 2a having thin walls have a flat side or sides enabling the doffing devices or strippers 30 to engage larger portions of the tube 2a than if the spindles were wholly cylindrical. The cop holder is rotatable about a horizontal shaft 25 and is retained in its working position by a spring detent 29. The tube 2a mav be retained on the peg 24 by springs 101, Fig. 6, accommodated in a slot 102 formed in a plate 99, Fig. 10, the strippers 30 engaging lugs 100 on the plate 99 when doffing Alternatively, the peg 24 is grooved and the plate 99 provided with projections engaging therein, or the peg may be slotted and a rod slidable therein. In a modification, the cop holder is rotatable about a vertical shaft 25, Fig. 14, and the pegs 24, pivoted at 88, are turnable by engagement with bearing surfaces 92, 93 into a vertical position for delivering yarn or horizontally to receive a fresh cop, Fig. 15. The plate 90 serves as a guide member and as a stripper. The hub 87 of the holder is connected to a spider member 95 having notches for detent springs 29. The holder may be moved by means connected with the conveyer, while the cops may be placed on the pegs 24 by the devicedescribed in Specification 398 655. The skewering device comprises bell cranks 41, 41a, Fig. 22, mounted on a common rod 41b under the troughs 39, into which the bobbins 2 are delivered from the container 35. The bell cranks may be operated by a feed device mounted on the conveyer or by rods 107 actuated by pedals 108. On the return movement of the rod 107 due to the spring 109 a spring pawl 42 on the arm 41a engages the downwardly directed peg 24 and moves the holder one step. Instead of moving the fresh bobbin or cop towards the peg the latter may be pushed into the cop tube. The holder 12, Fig. 24, is rotatable on a bracket 13 fixed to a rod 13a which is slidable in the frame members 7, 7a, 7b. The bobbins 2 are delivered from a container 35 which is. provided with an inclined abutment 15 adapted to engage a pin 11 on the rod 13a and move the holder to the left, the downwardly directed peg 24 passing beyond a spring pawl 42. When the abutment 15 releases the holder 12 it is moved outwardly by the spring 23 and is rotated one step by the pawl 42, the fresh cop reaching the delivery position and the empty tube being removed by the stripper 30. Alternatively, the rod 13a is operated by a pedal through a rod and a bell-crank lever. In a further modification, the cop holder is mounted in a member 13 formed as a bell crank pivoted at 37, Fig. 31, the cop being held in the inclined trough 39 and the holder actuated by an abutment 15 or by a pedal 108. In another form employing a single peg or spindle 24 the spindle is telescopic, the bobbin-bearing peg being pressed outwardly by the spring 46, Figs. 34 and 36. The abutment 15 is adapted to engage pins 53 on a gear 48 and thus rotate the gear 47 on the shaft 25, and the peg or spindle 24, through one revolution. A shoulder 24b is arranged to engage the inner curve of the cam 54 and thereby to cause the peg to be withdrawn from the empty tube which bears on the outer edge of the cam, the end of the spindle 24 after three-quarters of a revolution being pressed forward horizontally to enter the fresh bobbin and then regaining its vertical position. In a modification, the bobbins 2 may be supplied on an endless conveyer and the spindle rotated by ratchet and pawl' gear actuated by a pedal. In another form the spindle 24 is formed in one piece and is carried in a frame member 59, Fig. 39, an arm 62 on the lower end of the spindle being engaged by the abutment 15 and the spindle removed from the empty bobbin which falls down the incline 63. The trough 39 carrying the fresh bobbin 2 is carried by an arm 65 pivoted at 66 and is raised vertically by an inclined edge 68, and the spindle 24 being released by the abutment 15 is moved up by the spring 46 into the bobbin 2. A further abutment returns the trough 39 to its original position. The spindle 24 and trough 39 may alternatively be actuated by a pedal device. In a further modification, the spindle 24 is moved downwardly by an abutment or a pedal 108 and is also rocked to an inclined position the fresh bobbin sliding from the container, or the trough, on to the spindle which is then raised by a spring and turned vertically.
