Definitions

  • SeriahNosZSfifiAO invention relates to improvements in yarn carriers of knitting tmachines and partioularly those used in machines of thetraversing yarn .feed type which are used for the production of flat fashioned hosiery blanks and in which the yarn carriers are for-med with yarntguide tubes attheir lower ends tolay the yarns across the nibs of the sinkers in feeding the yarns to the needlesiof the machines.
  • the yarn carrier tubes are either resilient vor capable of being :swung upon striking anobstruction such as :a displaced sinker with the object of avoidin damage to the 'sinkers or other machine :parts.
  • the main object of this invention is to provide a.;yarn,carrier of the swingable tube type wherein the tube is carried within .a mounting pivoted pon the. face of the tip portion of theyarn car rier finger whereby-the tube is capable of being swung aside should it contact an obstruction such as a displaced sinkenthe tube mounting being so arranged that the tube may be readily removed and replaced by the operator without the use of any tools.
  • a further and important object of my invention i to form the carrier finger of very thin sheet steel and to mountthe yarn tube upon the face of the finger tip which is an integral part of the finger, the tip resiliently bearingagainst the tube toaretainrit in its. normal operating position.
  • a still further object oithe invention is the provision of a pair of protuberances upon the face :of theouter end portion of the finger tip and between the sides of which the tube is normally positioned, the resiliency of the tip and the height of the protuberances being so arranged that the tube .will swing over one of the protuberances against th resiliency of the tip should the tube strike an obstruction such as a displaced sinker.
  • Another object of the invention is the provision of a tube with acollarat its upper end which is positioned ,to bear against the tube mounting to prevent the tube fromsliding downwardly .orforwardly ,along the finger tip.
  • a further object is the provision. of a second protuberance upon the face of the inner portion of the finger tip at a point adjacent to the inner end .face ,of the tube for limitin ,the movement .of the tubein, an inward or upward direction on the finger tip; the second protuberance bein so vP FQnor-tinned that it retains the tube against inward oi upward ⁇ 2 movement should the tube beswung :upon strikingan obstruction but permits the tube to he slid upwardly. .aiter it is manually swung -a furtherdegree order to efiect removal of the tubefrom the-carrier.

  • FIG. 4 is .a-greatly-enlarged front .elevational view .of the tube carrying tip portion of the carrier finger.
  • Fig. .5. is an end elevationalview of the carrier finger tip as shown in Fig.4.
  • Fig. dds a longitudinal cross sectional view through the carrier finger tip, .being taken through the line -6--6 Fig. 4.
  • Fig. 7 is a perspective view vof a fragmentary portion .ofthe finger tip and showing the orifice therein within which the tube. mounting. ispivtotally contained, .and
  • Fig. 8 is.a perspective viewof the tube mounting or turret which is contained within the orifice in the tipas illustrated in Fig. 7.
  • While most carriers aresodesigned that the tube is c0ntainedvvithin the thickness of the finger .I depart from this standard arrangement by forming my carrier.
  • This construction I provide a strong rigid carrier of very light weight and wherein the tip portion is resiliently set at an inclination to the face of the body portion to resiliently bear against the side of the tube carried thereon.
  • Figs. 1 and 2 illustrate the complete carrier which consists of a finger 2 and an integral tip 3, set at an inclination to the finger.
  • the finger 2 is longitudinally corrugated to provide the necessary rigidity, a central corrugation 4, as illustrated in Figs. 1 and 3, extending from the upper end of the finger to the inclination of the tip at the lower end of the finger and constituting a. groove along which the yarn passes to the tube.
  • the finger is formed with a conventionally shaped head 5 by which it is secured to the knitting machine.
  • An orifice 6, Fig. '7 is formed centrally of the upper portion of the tip 3, the orifice containing a mounting or turret within which the yarn tube is carried.
  • the turret comprises a circular hollow dome B which makes a snug rotatable fit within the orifice 6 and is formed with a circular flange 9 which rests against the under face of the tip 3, as illustrated in Fig. 6.
  • the dome 8 has .a pair of diametrically opposed orifices II] for the reception of the tube.
  • the dome B is formed with a curved. top wherein the sides I I of such top are substantially parallel to the axis of the orifices Ill.
  • the purpose of this dome formation is to furnish a relatively smooth upper turret surface wherein the sides H of the dome may be said to merge into the face of the tip 3 for the purpose of obviating the possibility of the carrier tip assemblies fouling one another should the clearance between passing tips be set too small.
  • the turret dome is furthermore so proportioned that the lower edges of the orifices I are spaced away from the adjacent face of the flange a distance which is only slightly greater than the thickness of thefinger tip whereby the insertion of the tube through the orifices If! in the dome draws the face of the dome fiange 9 into close contact with the bottom face of the tip 3.
  • the skirt l2 of the dome 8 is preferably of imperceptible inverse frusto conical form, its upper major diameter being minutely fractionally larger than the orifice 6 in the carrier tip whereby the dome of the turret is snapped into place .in its receiving orifice 6, and will not fall out of the orifice when its tube is removed.
  • the orifices [0 within the turret dome are so dimensioned that the tube l3 extending therethrough is a relatively close fit, and in order to prevent the tube from sliding downwardly or outwardly along the tip after it is set in position, the tube is formed with a collar 14 upon its upper end and which bears against the outside face of the turret dome, as will be seen upon reference to Figs. 4 and 6.
  • the outer end portion of the tip 3 is formed with a pair of protuberances l5, and between the sides of which the tube normally rests, as illustrated in Fig. 5.
  • the tip 3 is resiliently set so that its protuberance containing outer end portion bears towards and exerts pressure against the side of the tube so that the tube is normally firmly seat- 4 ed within the valley I6 formed by the sides of the protuberances I5, but is capable of being swung aside against the resilience of the tip under impact.
  • a curved protuberance I! is formed upon the face of the tip 3 concentric with the turret dome 8 and adjacent to the inner end of the tube l3.
  • the collar I 3 upon the tube bears against the curved protuberance I! to restrain the tube against upward movement.
  • the finger and tip of the carrier from sheet steel of approximately .015 inch or less in thickness, and as standard tubes generally have an outside diameter of .035 inch or more, it will be seen that the thickness of my carrier and tip is less than the diameter of the supported tube.
  • the operator can remove and replace a tube solely by the use of the fingers, the first step being to push the protruding end of the tube to one side across a protuberance 15 against the resiliency of the tip and to then swing the tube to the removal position.
  • the replacement tube can be readily threaded through the orifices l9 within the turret cap 8, and when the collar l4 rests against the turret, the tube and turret may then be swung into the operating position as shown in full lines in Fig. 4.
  • a yarn carrier for straight knitting Inachines comprising a finger having a tip resilient- 1y set at an inclination to the face of the body of the finger, a rigid guide tube for the yarn which is to be fed to the needles of the knitting machine and pivotally mounted upon one face of the resilient tip intermediately of the length of the tube and projecting from the end of the tip, and the outer end portion of the tip exerting a resilient pressure against the side of the tube.
  • a yarn carrier as claimed in claim 1 wherein a pair of protuberances are formed upon the face of the resilient tip and between the sides of Which the tube is normally positioned.
  • a yarn carrier as claimed in claim 1 wheren the guide tube extends through an orifice in a mounting pivoted upon the face "of the tip, the portion of the tuberemote from the end of the tip being formed with an enlargement of greater size than the size of theorifice in the tube mounting to constitute a stop for limiting the movement of the tube in one direction in the mounting, and a pair of protuberances formed upon the faceof the outer end portion of the tip and between the sides of which the tube is normally positioned.
  • A. yarn carrier as claimed inclaim L wherein the tube mounting contains an orifice through which the tube extends, an enlargement of greater size than the orifice in the mounting and formed upon the end of the tube remote from the outer end of the finger tip to constitute a stop for limiting the movement of the tube in an outward direction in the mounting, a protuberance formed upon the face of the inner portion of the finger tip at a point adjacent to the transverse surface at the inner end of the tube for limiting the movement of the tube in an in- Ward direction in the mounting, and a pair of protuberances formed upon the face of the outer portion of the tip and between the sides of which the tube is normally positioned.
