Definitions

  • This invention eliminates these deficiencies of such devices by providing for controlled movement or adjustment of the suction nozzles in such a manner as to make it'possible and practicable to swing or move these suction nozzles from their normal operating position close to the leaving side of the serrated rolls of the draft gear to a position further away; permitting easy and quick piecing or joining of broken yarn or threads.
  • the attached drawing illustrates diagrammatically the right and left hand drafting or feed rolls of a conventional spinning frame, designated I through 6 and I8 through 23 respectively.
  • the cops, bobbins or spools from which the entering yarn or thread I and 24 is unwound and the spindles on which th spun yarn or thread is rewound, as well as certain other parts of the spinning frame are not shown in the drawing since they are conventional and form no part of the invention.
  • the suction nozzles 8 and 25 on suction tubes 9 and 26 extend from a central collecting duct It to points just below serrated rolls 2 and I9. They are joined to the center collecting duct through flexible joints II.
  • the strong air suction or vacuum action so created at the tips or mouths of the suction nozzles causes lint, dust, broken yarn and the like to be drawn into suction tubes 9 and 26, and then pulled to collecting header Hi to the exhaust apparatus.
  • the exhaust apparatus is not shown in the drawing since it forms no part of the invention.
  • the nozzle tubes may be flattened at the tip or end to form an oblong or slot shape mouth.
  • the nozzles 8 and 25 are provided with mech- 7 Claims. (Cl. 57-345) anisms to make them adjustable. In the normal v operating position indicated by the solid lines, they are close to the rolls 2 and I9, and in the position indicated by the dotted lines they are removed from these rolls. As indicated by the arrows, these nozzles are adjustable in a plane vertical to the axis of thevserrated rolls. The nozzle mouths, as shown, are located at 12 and 21 in the low or down" position. To prevent the nozzles from striking the serrated rolls, the adjustability or movement of the nozzles is limited. For this purpose, clamp I3 with bandiron extension I l is fastened to nozzle tube 9. To this extension a spring I 5 is fastened.
  • Spring l5 snaps into a formed or bent rod ll serving as a stop member and which is fastened to the spinning frame traverse H5.
  • the bent rod l1 and the bent spring [5 act as stops which control the normal working position of nozzle 8 and therefore also the nozzle tube 9. Movement of the nozzle tube in the direction of the arrow is limited by extension I, which rests on machine traverse l6 as shown on dotted lines in drawing.
  • FIG. 25 An alternative arrangement for limiting the swing or movement is shown on the left hand side of the drawing at nozzle 25.
  • the nozzle tube 26 also carries clamp 34; which has a pin 35 located vertically as shown.
  • a U-bent :bandiron 36 is riveted to machine traverse 29.
  • the U-bent bandiron has a slot extending from points 3
  • Springs 33 is attached to the bandiron and arranged-to snap into a stop member such as the pin 35 to hold nozzle tube 26 in its up or normal operating position.
  • the arrangements described are so designed as to easily overcome the effect of springs l5 and 33 so that nozzle tubes 9 and 26 can be brought from the upper to the lower position without exertion. 0n the other hand, springs l5 and 33 are sufliciently strong to hold firmly when the nozzle tubes 9 and 26 are moved from the lower to the upper position.
  • the normal working position of the yarn running from the serrated rolls to the spindles is indicated by I. Should the yarn or thread break, a position indicated by 24' results. The lower end of the broken thread, which is shown as arrow 24' on the drawing, is wound onto the spindle of the spinning frame. The upper end is sucked in by nozzle 25 and passes into nozzle tube 26. The broken thread cannot therefore tangle up with threads of adjacent spindles. The operator, after discovering the break, first swings nozzle 25 to position 21 without stopping the draft gear. The yarn continuously fed or delivered by the draft gear is sucked into the nozzle.
  • the free broken thread between the serrated roll l9 and the nozzle is sufficiently long to enable the operator, in case of both short or long staple material, to piece or join the spindle end of the broken yarn while draft gear is running and at the same time cut off the yarn end sucked into the nozzle.
  • the normal working position of the thread 1 is again established.
  • the nozzle tube is still in the lower position. In this lowered position, experience has shown that the suction nozzle is not able to keep the serrated rolls clean and, in case of another breakage, cannot prohibit the yarn from lapping around the roll or tangling with the other yarn or threads. Therefore, after piecing the broken yarn, the nozzle is immediately brought back to the upper position to keep the rolls clean and pick up or catch the next broken thread.
  • the described arrangement of the suction nozzles makes possible for the first time the spinning of long staple material without troublesome interruptions.
  • the distance which the nozzle may be swung from its normal operating position equals the width of one or two fingers, enabling the operator quickly and efficiently to piece or join broken yarn or threads together.
  • the nozzle mouth of each nozzle must be well rounded and smooth.
  • the nozzle mouth is preferably made of hard and wear-resistant material, for instance steel, glass or hard aluminum.
  • other devices than those shown in the drawing may suggest themselves.
  • the nozzles of such a group may be mounted on a common connecting unit, which in turn may be coupled by a flexible joint, such as a rubber tube, to the common collecting header leading to the exhaust apparatus.
  • a suction nozzle placed adjacent the leaving side of the rolls for eflecting exhaust and trapping of dust, lint, and broken yarn
  • a collecting duct a flexible joint connecting the nozzle to the duct and means for holding the nozzle in normal position adjacent the leaving side of the rolls
  • said means including a stop member and a flexible member adapted to snap into contact with the stop member to hold the nozzle in normal position adjacent the leaving side of the rolls, disengagement of the flexible member from the stop member permitting the nozzle to be moved to a point remote from the rolls whereby working room is provided for efficient piecing of a broken yarn caught by the nozzle with the spindle end of the broken yarn.
  • Apparatus according to claim 1 in which the nozzle is moved in a plane substantially perpendicular to the axis of the rolls, yarn from the rolls being fed across the mouth of the nozzle when the nozzle is in normal position.
  • a suction nozzle placed adjacent the leaving side of the rolls for eifecting exhaust and trapping of dust, lint, and broken yarn, a collecting duct, a flexible joint connecting the nozzle to the duct and means for holding the nozzle in normal position adjacent the leaving side of the rolls, said means including a clamp secured about the nozzle, an extension member secured to the clamp, a spring carried by the extension member, a rod member supported by the frame, said spring snapping into contact with the rod member to hold the nozzle in normal position adjacent the leaving side of the rolls, disengagement of the spring from the rod member permitting the nozzle to be moved to a point remote from the rolls whereby working room is provided for eflicient piecing of a broken yarn caught by the nozzle with the spindle end of the broken yarn.
  • a suction nozzle placed adjacent the leaving side of the rolls for effecting exhaust and trapping of dust, lint, and broken yarn, a collecting duct, a flexible joint connecting the nozzle to the duct, and means for holding the nozzle in normal position adjacent the leaving side of the rolls, said means including a clamp secured about the nozzle, a pin mounted on the clamp, a member having a slot therein mounted on the frame, the nozzle projecting through the slot, a spring mounted on said member adapted to snap into contact with the pin to hold the nozzle in normal position adjacent the leaving side of the rolls, disengagement of the spring from the pin permitting the nozzle to be moved to a point remote from the rolls whereby working room is provided for eflicient piecing of a broken yarn caught by the nozzle with the spindle end of the broken yarn.
  • a spinning frame including a plurality of sets of drawing rolls, a plurality of suction nomles placed adjacent the leaving sides of the sets of rolls for effecting exhaust and trapping of dust, lint and broken yarn, a collecting duct, flexible joints connecting the nozzles to the duct, and means for separately holding the nozzles in normal position adjacent the leaving sides of the rolls, said means including stop members and flexible members adapted to snap into contact with the stop members to hold the nozzles in normal position adjacent the leaving sides of the rolls, disengagement of any flexible member from its cooperating stop member permitting a nozzle to be separately moved to a point remote from the rolls whereby working room is provided for efllcient piecing of a broken yarn caught by such nozzle with the spindle end of the broken yarn.
