Abstract: 2267. Prause, R. Jau. 29. Flyer frames ; spindle apparatus; fresh sets, arrange- ments for commen- cing; stop appara- tus, non-automatic; tin rollers ; bobbins. -The flyers 1, Fig. 1, are mounted in- dependently of the spindles 28 in long bronze conical bear- ings 6, and are driven from drums 11 by bands 9 passing round wharls 7 which are screwed on the conical journals of the flyers, and bear against hardened-steel discs provided with lubricating- grooves. The drums 11 are constructed with parts of one diameter, alternating with parts of a smaller diameter, as shown in Fig. 11, the bands 9 being moved on to the larger parts for driving the flyers, and, when the flyers are to be stopped, on to the smaller parts, which may be surrounded by loose sheet-metal rings 11<1> pro- vided, in some cases, with circumferential corru- gations to reduce the bearing-surface. A pedal 12, Fig. 1, is depressed and acts through a rod 13 to rock forks 14 for moving the bands from the larger to the smaller diameters of the drums, the bands when so transferred being nipped between the forks and fixed projections so that their motion is quickly arrested. A pawl 16 locks the pedal in its depressed position, and when released, the pedal descends by gravity to return the parts, an inclined projection 17, Fig. 11, on one edge of each larger part of the drum facili- tating the transfer of the bands. The bobbin spindles 28 are fixed to tables mounted round a frame which may be rotated to bring any row of bobbins under the flyers, a spring catch engaging a notch in a ring at one end of the frame at each working position. The bobbins 2, Fig. 3, are freely mounted on rotatable sleeves 29 on the spindles, and rest on carriers 30, preferably saucer- shaped with coned rim, into which the sleeves are screwed. The carriers are supported by, and rotate on, ground metal discs 31, and the lower flange of the bobbins is grooved to receive a brake cord 32 connected at each end through springs 33 with the points of support. One of the bars 34 over which the brake cords pass extends along the row of bobbins, and can be moved longi- tudinally by a pivoted lever 35 to carry the cords clear of the bobbins when required. After a row of bobbins has been filled, the machine is stopped and the flyers are brought into position to allow the bobbin frame to be rotated so as to bring a row of empty bobbins below the flyers. This positioning of the flyers is effected by forming the upper part of each flyer wharl as a pinion from which the teeth are removed over two dia- metrically-opposite arcs, and providing a rack 20, Fig. 1, normally clear of the pinions and connected by spring-pressed links to a bar 23 which can be moved longitudinally by a screw and handle. The movement of the bar carries the rack along, and an inclino on the rack is brought against a sta- tionary spring finger 27, whereby the rack is pressed forward into gear with the pinions and rotates them until their blank portion comes opposite the rack, leaving the flyers in the required position. The incline now permits the spring links to draw back the rack towards the bar 23. The rotation of the bobbin frame when a row of bobbins is filled lays the threads over a transverse trough 40, along which a knife is run to sever the threads. On restarting, the cut ends are automatically wound on the fresh bobbins, and the attendant can then replace the filled bobbins by empty ones and apply the brake cords to retain them on the spindles. A bar extend- ing along the front of the machine is connected to the usual starting and stopping lever.
