Definitions

  • the object of this invention is to provide improved means for adjusting the relative positions of the elements of the drafting apparatus of textile spinning machines, in order that the inter-element spacings may be adjusted to fine limits uniformly throughout the length of a machine or a section thereof.
  • the invention provides a series of stationary leadscrews disposed in parallelism at intervals along the frame, there being one such lead-screw in respect of each fore-and-aft assembly of drafting element bearing supports, each of which supports is individually connected to said lead-screw by a captive nut so that by rotation of the latter the bearing support can be adjusted in the direction of the path of the fibrous material under treatment, and the nuts of all the corresponding bearing supports are collectively rotated by a longitudinal worm operated from the end of the frame (or section thereof).
  • the bearing supports of the rear elements are collectively adjusted simultaneously by one worm
  • the first intermediate elements are adjusted by a second Worm, and so on, a separate worm being provided for each corresponding set of elements.
  • Fig. 1 is a side elevation of the adjusting apparatus relating to one fore-and-aft assembly of drafting element bearing supports
  • Fig. 2 is a view thereof as seen in the direction of the arrow A of Fig. l
  • Fig. 3 is a sectional detail taken on the line IlL-III of Fig. 1.
  • FIG. 1 show the members of a single fore-andaft assembly of drafting elements.
  • Such members comprise front rollers 10, 11; a pair of front intermediate carrier rolls 12, 13; a pair of rear intermediate carrier rolls 14, 15; and a pair of back rollers 16, 17.
  • the front rollers 10, 11 are mounted in fixed bearings, the bearing of the lower front roller 11 being supported by a bracket 18.
  • the roll pairs 12, 13, 14, 15, and 16, 17 are each mounted on a common support member 19, 20 or 21, said support members 19, 20, 21 being carried by blocks 22, 23, 24, respectively, each of which houses a rotatable captive nut 25 by which it is located upon astationary lead-screw 26 the extremities of which are fixed respectively in the bracket 18 and a bracket 27 which is mounted at the rear of the apparatus.
  • the nut 25 takes the form of a worm-wheel which is arranged to mesh with a longitudinally disposed wormshaft 28, which is adapted to be rotated manually at the end of the machine.
  • the blocks 22, 23, 24 are each attached to or made integrally with a bracket 29 (Fig. 3) which incorporates a bearing for the worm-shaft 28 and is bored to slide upon a guide-bar 30 supported between the brackets 18 and 27.
  • a separate lead-screw 26, with the cooperative nuts 25 is provided in respect of each fore-and-aft assembly of drafting element bearing supports along the length of the frame.
  • a scale 31 in relation to which each of the blocks 22, 23, 24 is provided with a pointer 32 whereby the fore-and-aft position of the block, and therefore the inter-element spacing existing at a given adjustment, is indicated on the scale 31.
  • a worm-shaft brings about the rotation of the worm-wheel nuts 25 of all the blocks of a line of carrier elements or back rollers, said nuts rotating on their fore-and-aft disposed leadscrews 26 and taking with them the blocks 22, 23 or 24 with their respective pairs of roller elements.
  • the term drafting element used herein is intended to include the intermediate carrier rolls 12, 13 and 14, 15.
  • a drafting apparatus of a textile frame including a plurality of draft assemblies, each having a pair of front rollers, at least one pair of intermediate carrier rollers and a pair of back rollers, said assemblies being arranged in spaced locations along the length of the textile frame, the improvement comprising; a stationary lead screw supported on said frame, individual brackets rotatably supporting each of said intermediate carrier rollers and said back rollers, said brackets each having a captive nut rotatable therein and said nut positioned over said lead screw and having an internal threaded portion in operative engagement therewith, said nut having external teeth, and means including a worm-shaft having teeth in engagement with the external teeth of said captive nut to rotate the latter and shift the position of said bracket and said rollers along the axis of said lead screw as desired.
  • a drafting apparatus of a textile frame including a scale mounted on said frame adjacent said lead screw, and pointer means attached to said brackets and including a portion overlying said scale to indicate the relative position of said pairs of rollers.
