Definitions

  • This invention relates to the art of textile drafting and to a needle bar mechanism for drawing frames and similar machines for processing wool or other long fibers preparatory to spinning.
  • the principal objects of the present invention are to provide protection for the needles against damage from such cause and to minimize the formation and facilitate the removal of such fiber accumulations.
  • Fig. l is a longitudinal, vertical section on the line 1--1 of Fig. 2, of a drafting unit embodying the invention, parts being omitted for clearness of illustration;
  • Fig. 2 is a top plan view of the unit with the top rolls part sectioned removed, partially broken out and in on the line 22 of Fig.
  • Figs. 3 and 4 illustrate the needle bars
  • Fig. 5 is a section of the line 55 of Fig. 2;.
  • Fig. 6 is a section on the line 6-6 of Fig. 2;
  • Fig. 7 is a broken out sectional view illustrating the action of the needles.
  • Fig. l of the drawings the illustrated unit is shown as incorporating a frame 10 on which are mounted top and bottom back rolls, 11, 12, a top front 10.
  • the shaft of roll is the driven shaft of the unit 2,847,718 Patented Aug. 19, 1958 and shaft 19 and the shaft of rolls 14 and 12 are driven from it through gears 22, 23, 24, 25, 26, 27 and 28.
  • the desired draft between the back and front rolls and also the tension draft between shaft 19 and the back rolls is obtained by appropriate selection of these gears.
  • the needle bar mechanism comprises a frame or carrier in the form a a sleeve 29 mounted on and secured to shaft 19 as by set screw 30 and having at its ends, flanges or spaced disks 31, 32 provided with peripherial openings for removably supporting the needle bars.
  • Two series of such bars are employed, the bars: of one series being like the bar 33 of Fig. 3 and the bars of the other series being like the bar 34 of Fig. 4.
  • the bars ofthe two series are of similar construction but reversed, end for end.
  • the reduced ends 35 of the series of bars 33 are located in openings 36 of frame disk 32 and the opposite ends of these bars seat in slots 37 of disk 31.
  • each frame disk has a series of alternating holes and slots receiving the alternately, oppositely disposed needle bars.
  • split collars 41 and 42 are clamped needle bars serves to hold erect or substantially normal to the travel of the fibers, the needles which are in engagement with the fibers or those which for convenience may be referred to as being in the working section of the cycle.
  • each set of needles would be free to be pulled forward by the fibers themselves, thus insuring that in the indicated zone, the fibers and needles travel at the same speed.
  • each bar 33 is provided with a head 48 at one end and carrying a crank pin 49 on which is mounted a bearing 50.
  • each bar 34 is provided with a head 51, crankjpin 52 and bearing 53.
  • a brush is mounted on theframe, the axes of the lower front rolls and of the frame being angularly disposed about the axis of the brush.
  • the brush carries alternating series of long bristles 71 and shorter bristles72, the distance of the frame axis fro-m the brush axis being such that all of the bristles sweep a. portion of the path of the needlesand the distances of the. roller axes from the brush axis being such that the short bristles clear and the long. bristles sweep portions of the peripheries of the lower front rolls.
  • This relieved portion starts at a point adjacent or opposite to the relievedportion. of the outer track surface and terminates adjacent but in advance of the cleaning zone, that is, the zone where the brush is illustrated as sweeping a portion of the path of the needles in Fig. 1.
  • a drawing frame needle bar mechanism comprising the combination of a rotatable needle bar frame incorporatingrigid, spaced disc portions; a series of needle bars extending between and rotatably supported by said disk portions; needles carried by the bars for entry into and Withdrawal from the fibers under treatment upon rotation of said disk portions; a stationary cam track adjacent the outer sideof at least one of said disk portions, said track including inner-andoutertrack surfaces; needlebar crank members engaged with the said track surfaces to position the needle bars with respect tottheir axes; the.cam track'surfaces having successive relieved sections adjacent the zone ofwithdrawal of the needles from the fibers, the said relieved sections located one in the outer track surface and thegother inthe inner track surface and thereby affording the needle bars freedom of. movement first in one direction and then in the opposite direction.
  • a drawingframe. needle bar, mechanism comprising the combination of a rotatable needle bar frame incorpo:
  • thecam track surfaces eachhaving a'relieved sectionadapted to free the crank members. and permit rotation. of the needle bars. about their axes, the relieved portion. of. the outer track surface being located adjacent the zone of withdrawal of the needles from the fibers and in advance of the relieved portion of the inner cam track surface.
