Abstract: 153,590. Brabant & J. Vandier, E. & G. Nov. 5, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Winding-machines; clearing-apparatus; stopmotions; stop-apparatus, non-automatic; tension arrangements.-Relates to a drum winding- machine for winding or doubling and gassing yarns or threads, and comprises a sliding weighted vertical bobbin-carrier; a bobbin spindle; a bobbin driving cylinder arranged between the slit drum and the bobbin; means operated manually or automatically, on breakage or completion of the winding, for raising the driving-cylinder from the slit drum, for freeing a retaining-lever on the clearer whereby the yarn may be moved therefrom, and for removing the yarn from, and raising the lid of, the gassing-apparatus; means for reducing the pressure of the bobbin on the driving-cylinder and for reducing the tension on the yarn as the cop grows; and means for automatically inserting the yarn into the slit of the drum when commencing winding. The bobbin spindle 15, Fig. 5, is provided with a spring- pressed pin 18, and is mounted between centres on a stirrup 1, Fig. 3, which is provided with spring-pressed rollers 3 and slides on vertical standards 2 and is connected with a pulley 6, Fig. 1. The bobbin-driving cylinder 11, Fig. 5, revolves on centres, of which one is mounted in a slide 26, and is provided with a boss 29. The axes of the pulley 6, the spindle 15, the cylinder 11, and the slit drum are in the same plane. The standards are provided with rings to limit the upper position of the stirrups and notches 74 to hold the stirrups during piecing. The pulley 6 is provided with a weight 7 so arranged that as the bobbin increases the pressure of the bobbin on the cylinder 11 decreases, and is connected by a chain 72 with a tension surface 70 so that, at the same time, the tension on the yarn is reduced. A lever 30, Fig. 4, is geared with the cover 37 of the gassing apparatus, is connected by a chain or cord 69 with a spring-pressed lever 67 which normally closes the slit of the clearer. and is provided with a ramp 48, normally held by a spring-pressed pin 51. The levers 30 may be operated by hand to stop all the bobbins by means of a shaft 62, Fig. 1, and each lever may be automatically operated by means of the drum shaft which engages a hammer 56 pivoted on the lever 30 and normally upheld by the yarn. The hammer is released upon breakage, and is operated upon completion of the bobbin by means of a weight 77 on a pulley rotating with the pulley 6, so that it engages with the rotating drum-shaft and the lever 30 is pushed forwards, whereby the ramp 28 lifts the driving-cylinder 11 and presses the polygonal boss 29 thereon against a brake surface, the cover of the gassing-apparatus is raised and the yarn removed from the flame and the lever 67 is operated to expose the slit of the clearer. A pivoted rod on the lever 30 carries a roller which travels along a fixed guide 'and prevents the hammer from falling too far. The parts are restored to working position by a handle 52. The cover of the gassing-apparatus carries adjustable inverted V-shaped guides which lead the yarn between adjustable V-shaped guides on the burner. The front portion of the cover is recessed and the width of the recess is regulated by adjustable cheeks 41, a corresponding recess 42 in the apparatus communicating with a duct 43 connected with a collector in which a suitable degree of vacuum is maintained. The yarn is passed around a metal rod 75 and through an open hook 76, Fig. 3, so that, when starting, the tension draws the hook down and the yarn automatically enters the slit of the drum when the slit coincides with the path of the yarn stretched between the rod and the hook.
