Definitions

  • the present'invention relates to a suction device for collecting and removing broken ends in passages and the fact that the cross sectional areas of the passages are not properly propore tioned so as to insure a uniform distribution of the suction draft over the entire arrangement of passages.
  • the dimculties encountered in the operation of prior devices are overcome by constructing the main collecting conduit and the individual suction heads of varying cross section throughout, always increasing in area in the direction of movement of the broken ends through the suction heads and main collecting conduit toward the suction source.
  • the device will operate continuously, without clogging, by reason of the uniform flow of broken ends in the suction stream and the absence of eddy currents that would otherwise tend to deposit the broken ends as a mass at any point in the system where a back eddy exists.
  • FIG. 1 is a longitudinal sectional view of an individual suction head embodying the invention
  • Fig. 2 is a transverse section along the line II-II of Fig. 1,
  • Fig. 3 is a plan view of. an assembled collecting conduit and suction heads
  • Fig. 4 is a transverse section through the conduit, along the line IV-IV of Fig. 3, and
  • Fig. 5 is a diagrammatic view, partially in section, showing the installation of a device embodying the invention in association with. a spinning machine.
  • FIG. 5 there is shown 9. Portion of a spinning frame providing spools I from which roving 2 is drawn by rolls 3 for winding on spindles 4 in a manner usual with the operation of spinning machinery.
  • a conduit 5 extending longitudinally of the machine, this conduit bein readily built into the existing machine below the creel or spool stand 6.
  • the conduit 5 preferably is of rectangular crosssection, as shown in Fig. 4, with its right hand end closed, as viewed in Fig. 3, and its opposite open'endconnected to a suitable suction source, as indicated at I. It is to be noted that the conduit 5 is tapering in form, as viewed in plan, so that the cross sectional area thereof increases from its closed end toward the suction source.
  • each suction head 8 provides a series of individual suction holes 9 so spaced along the head so as to substantially coincide with the individual rovings 2.
  • each suction head 8 is of generally circular cross section, as shown in Fig. 2, each head is tapered longitudinally so that the head is of varying cross section throughout, increasing in area from the closed end of the head to its connection with the main conduit 5.
  • suction holes 9 increase in size from the suction end to the closed end, as shown in Fig. 1, in inverse relation to the taper of the head itself.
  • a device for collecting and removing broken ends in spinning and like machines comprising in combination a collecting conduit extending longitudinally of the machine, said conduit being closed at one end and being connected to a source of suction at its other end, with said conduit being of varying cross section always increasing from said closed end to said suction end, and a series of suction heads projecting at intervals from said conduit and each providing hollow portions extending parallel to said conduit, having spaced openings into which broken ends from the machine are adapted to be individually drawn towards said source of suction, with said portions 01' the suction heads each being of varying cross section throughout, increasing in area in the di-- 20 recti'on of movement of broken ends through said openings toward said suction source.
  • a device for collecting and removing broken ends in spinning and like machines comprising in combination a collecting conduit extending longitudinally of the machine, said conduit being closed at one end and being connected to a source of suction at its other end, with said conduit being of varying cross section always increasing from said closed end to said suction end, and a series of hollow suction heads projecting at intervals from said conduit each providing spaced openings into which broken ends from the machine are adapted to be individually drawn, with said openings increasing in size along said heads in a direction away from said suction source, and with the cross section of each head increasing in the direction of movement of broken ends through said openings toward said suction source HEINRICH THOMA.
