Abstract: 398,655. Creel-apparatus for yarnwinding frames and devices for supplying bobbins thereto. REINERS, W., 48, Rheydterstrasse, Gladbach, Munich, Germany. Oct. 8, 1932, No. 28110. Convention date, Oct. 8, 1931. [Classes 120 (ii) and 120 (iii).] In a yarn-winding frame of the kind in which a mechanical conveyer conveys supply bobbins to the creel spindles, the bobbins being automatically placed in their charging and working positions and means being provided for automatically stripping the empty bobbin tubes from their pegs, mechanism is provided whereby a number of bobbins apportioned to a group of spindles are transferred simultaneously from the conveyer to the spindles by gravity or by a single skewering device. The bobbins 2 are fed from a magazine on to an endless carrier chain 17, Fig. 1, which stops as soon as all the winding points have been supplied. A trip device 15 is provided on the conveyer 17 to rotate the bobbin holders 12 and a fixed curved finger 16 to push each empty tube off its peg. The bobbins are then pushed on to their holders 12 by a skewering device 18 operated by a hand lever 23, or by a cam-actuated lever 44, Fig. 33. The cam drum 39 and the sprocketwheel 43 driving the chain 17 are mounted respectively on shafts 36, 30 and are controlled by clutch dogs 34, 31 moved by a lever 32 pivoted at 33. As soon as the trip lever 15 has actuated the last holder 12 of the series which it serves a finger 46 thereon engages a finger 45 on the lever 32 and moves it to the position shown in Fig. 33, the chain 17 being stopped and the drum 39 driven to actuate the device 18 and then to return it to its inoperative position. A projection 48 on the lever 32 then engages a projection in a groove 49 in the drum 39 and is moved outwards over a spring pin 51, the drum 39 being stopped and the chain 17 re-started. In a modification, the skewering device 18 serves also as a lifter for the bobbins 2, each bobbin resting on a support 62 on the member 18 and a notch 63 in a bar 61, Fig. 8. The members 18, 61 are lifted into skewering position by quadrants 64, Fig. 7, connected by a tie rod 65 and rotatable about rods 19. In another arrangement the bobbins 2 on the conveyer 17 are raised at their tapered ends by a bar 68 notched at 69, Fig. 13, and carried by levers 70 on a shaft 71 actuated automatically or by a hand-lever 73, the bobbins then sliding down a guide 74 on to the holders 12, Fig. 14. The trip device 15 is mounted on a separate chain 75. The bobbins may also be carried in inclined troughs 76 and retained by spring flaps 79, Fig. 20, the flaps being opened by a common control device 80-82 to allow the bobbins to slide down the guides 74, or the bobbins 2 may be fed from a travelling container 1 on to supports 84, Fig. 24, and skewered simultaneously by the members 18, 19, 21. The travelling container 1 may also be combined with inclined troughs 86, Fig. 27, the common supporting bar 85 being lowered automatically or by a hand lever 89. To prevent the charging and rotation of bobbin holders 12 carrying bobbins not fully unwound owing to breakage of yarn a feeler 90, Fig. 29, is provided pivoted at 91 on a holder 93 fixed to one side of the separate chain 75 and which carries the finger 15. When the feeler 90 strikes a residue of yarn on a bobbin it is moved from the dotted to the full line position, Fig. 31, and rocks the finger 15 to the full line position wherein it cannot engage behind the bottom empty pegs of the holder 12. Movement of the finger 15 also serves through members 96 .. 101 to disengage the clutch 102 on the shaft 103 of the star-shaped bobbin distributer 104 in the magazine 57, the clutch 102 being automatically re-engaged when the feeler 90 has moved past the bobbin having the residue of yarn. Alternatively, the clutch 102 may be uncoupled electrically, while in a further modification the yarn residue on the bobbin serves to hold the end 112 of the feeler 111 in the position shown in full lines for the three upper holders, Fig. 19, and an angular projection 114 on the finger 15 engages the end 113 of the feeler 111 which is rocked as shown in broken lines, the finger 15 being swung inwards. The tilting of a fresh bobbin, as in Fig. 14, is not prevented but the tilted bobbin drops back to the horizontal on the conveyer 17. Specifications 187,961 and 201,558, [both in Class 120 (ii), Spinning, twisting, &c.], are referred to. The Specification as open to inspection under Sect. 91 comprises also an arrangement for the release of a single supply bobbin at each winding point, the bobbin sliding by gravity down a shoot on to the bobbin holder. This subject-matter does not appear in the Specification as accepted.
