Definitions

  • ABSTRACT OF THE DISCLOSURE A twisting ring having a traveler engaging inner surface with a median radius of curvature of its median area equal to about one-half of the vertical dimension of the inwardly extending flange, a lower radius of curvature of its lower area equal to about three times that of the median radius with its center of curvature located generally vertically above the outer surface of the ring, and an upper radius of curvature of its upper area equal to about two thirds times that of the median radius with its center of curvature located generally in a horizontal plane extending through the center of curvature of the median plane, the lower and upper radii of curvature joining the median radius tangentially.
  • the upper medial surface of the ring flange includes a first surface forming a yarn abutment extending downwardly adjacent the traveler engaging inner surface and a second surface extending from the first surface to said outwardly extending flange end portion, whereby an enlarged yarn passageway is formed in said upper medial surface of the ring flange, the first surface forming the yarn abutment being positioned from the inner flange a distance of less than one-half the width of the flange.
  • the present invention relates to the art of spinning and twisting yarns and more especially to an improved traveler and a novel twisting ring for accommodating the traveler.
  • the ring shall be hereinafter described as a twisting ring, it should be understood that such term is employed in its broadest sense and is intended to include spinning rings as well.
  • the invention of the earlier application endeavored to overcome the above difficulties by providing a novel twisting ring having a web and a top flange provided with an enlarged inner bearing portion on which the traveler bears located in a plane generally above the plane of the outer flange portion whereby the longitudinal axis of the traveler will decline downwardly and outwardly thus providing a low center of gravity of the traveler with respect to the inner bearing area so as to ride on the outer flange portion in one of two running positions thereby providing a positive contact with the ring at two separate points and thus assuring that the traveler will run 3 ,354,628 Patented Nov. 28, 1957 in a predetermined fixed position, not affected by variation of the abovementioned forces. This was quite effective, but did not prove to be the entire solution to the problem.
  • the employment of such an enlarged area between the bearing surfaces is important in that it permits the use of a short traveler which permits full utilization of the bearing surfaces by eliminating the necessity of cutting away a portion of the same for passage of the yarn therebetween.
  • FIG. 1 is a transverse section of the ring and associated parts with the bobbin and traveler being shown in elevation;
  • FIG. 2 is an enlarged diagrammatic perspective illustration, in section, of a traveler and ring according to the invention
  • FIG. 3 is an enlarged detailed section of a ring according to the invention illustrating the traveler in its running position.
  • the spinning or twisting ring generally indicated by the numeral 20 is mounted on a holder 21 which is in turn secured in the upper face of the ring rail 23 of a spinning or twisting frame and has a substantially C-shaped traveler 22 slidably mounted thereon between which the yarn Y passes prior to be wound on the bobbin B.
  • the twisting or spinning ring of the invention includes a substantially vertically disposed annular web 24 and a top flange on said web having an inwardly extending flange portion, generally designated 26, and an outwardly extending flange portion, generally designated 32, said inwardly and outwardly extending flange portions being substantially semicircular in cross-section.
  • the inwardly extending flange portion is provided with a traveler engaging inner surface of unique configuration having three differing radii.
  • the central or median area 31 of inner flange portion 26 is provided on a median radius of curvature R of said surface equal to substantially three-eighths to five-eight-hs and preferably one-half of the vertical dimension of the inwardly extending flange poriton 26.
  • the lower area 33 of flange portion 26 is continuous therewith but has a much greater radius of curvature R equal to substantially two to four and preferably three times that of the median radius R which it tangentially joins, extending from that junction to the inner side of web 24. Its arcuate extent is substantially equal to that of median area 33.
  • the center C of lower radius R is located generally vertically of the inner surface of web 24, as shown in FIG. 3.
  • the upper area 35 of flange portion 26 is also contiguous with median area 31, but has a much smaller radius of curvature R equal to substantially one-half to five-sixt-hs and preferably two thirds times that of said median radius R' which it tangentially joins, extending from that junction to the upper rounded corner 37 of inner flange portion 26, in the specific embodiment shown, throughout an arcuate extent of about 75 degrees.
  • the center C of upper radius R is located generally in a horizontal plane extending through the center of curvature C of the median radius R
  • the radially outwardly extending portion 32 is of reduced thickness and includes a generally semi-circular flange surface 34 formed by radius r, which may be approximately one-quarter to one-half, but preferably about one-third of the median radius R
  • a straight undersurface 36 extends between the flange surface 34 and the outer side of web 24.
  • the upper surface of the flange is preferably shaped such that it generally declines downwardly and outwardly from the termination of the inner bearing surface at 37 to the outer flange surface 34. More specifically, the upper surface of the flange is preferably provided with an enlarged recess between the bearing surfaces providing ample clearance for passage of the yarn Y between the traveler and the ring. This recess is desirable in that, in addition to providing ample clearance for passage of the yarn, it also permits 'full utilization of the inner flange surface as a bearing area for the traveler.
  • the recess is formed by a first surface 38 forming a yarn abutment which slopes abruptly downwardly from the inner flange bearing surface at 37 at a substantial angle which may be approximately 45 degrees as illustrated, although the exact angle may vary dependent upon the range of yarn counts being processed. It has been found, for example, that fine counts require an angle considerably less than 45 degrees.
  • the surface 38 merges with a second surface 40 which preferably slopes at a small angle toward and adjoins the outer flange surface 34, however, the same may be horizontal if desired.
  • the yarn abutment surface 38 is preferably located less than half the radial width of the top flange from the inner bearing surface 26.
  • the specific location of this surface may be varied as desired, however, it has been found that best results are obtained when the upper extremity 37 of the surface 38 is located along the radial width of the flange less than one-half the width thereof, preferably -25 percent of said Width from the inner bearing surface 26.
  • the yarn passage recess has been defined as being formed by two intersecting surfaces 38 and 40, it should be understood that the same may be formed in other ways as by an arcuate configuration wherein a portion of the arcuate surface functions as an abutment for the yarn Y.
  • the substantially C-shaped traveler 22 includes an inner arcuate leg portion 42 so shaped as to bear on each of the contiguous inner flange surfaces 31, 33 and preferably throughout the entire arcuate extent thereof, and a similar opposed arcuate outer leg portion 44 which preferably is spaced from outer flange surface 34, with the leg portions 42 and 44 terminating in opposed horns 46 and 48, respectively, which are spaced from the Web 24.
  • the developed length of the traveler is hence relatively short and the conformation of leg portion 42 is substantially equal to that of the radii R R R3 of inner bearing surfaces 31, 33 and 35, thus assuring a substantially conforming fit between these surfaces.
  • the mass of the traveler is increased in order to provide additional stability and to assure that it will assume the desired running contact with the ring clear of outer flange 4 portion 32 substantially as illustrated in FIG, 3.
  • Other advantages of increasing the mass of the traveler are increased heat transfer and increased cross-section resulting in greatly extended traveler life.
  • the traveler 22 has been described as being of increased mass wherein the same will assume a low operating position, so that its outer leg portion 44 does not contact outer flange portion 34, one may, if desired, employ a traveler of decreased mass in order that upon reaching operating speed, the mass of the traveler will be overcome by centrifugal force. At this time, the traveler will attempt to level itself from its downwardly inclined position of FIG. 3 and will rise to an operating position with its outer leg portion 44 in contact with the lower surface of outer flange portion 34, as shown in dotted lines in FIG. 3.
  • a twisting ring having a substantially vertically disposed annular web and a top flange on said web having inwardly and outwardly extending flange portions Said inwardly extending flange portion having a traveler engaging inner surface with i a median radius of curvature of the median area of said surface equal to substantially three-eighths to five-eighths of the vertical dimension of said inwardly extending flange portion a lower radius of curvature of the lower area of said surface equal to substantially two to four times that of said median radius and an upper radius of curvature of the upper are of said surface equal to substantially one-half to five-sixths times that of said median radius said lower and upper radii of curvature being contiguous with said median radius.
  • a twisting ring as claimed in claim 1 wherein said inner flange portion is larger and substantially higher than said outer portion, the upper medial surface of said flange including a a first surface forming a yarn abutment' extending downwardly adjacent said arcuate inwardly extending portion and a second surface extending from said first surface to said outwardly extending end portion, whereby an enlarged yarn passagewayis formed in said upper medial surface of said flange, 7
  • said first surface forming said yarn abutment being positioned from the innermost surface of said inwardly extending portion less than one-half the width of said flange.
  • a twisting ring having a substantially vertically disposed annular web and a top flange on said web having inwardly and outwardly extending flange portions said inwardly extending flange portion having a traveler engaging inner surface with a median radius of curvature of the median area of said surface equal to substantially one-half of the vertical dimension of said inwardly extending flange portion a lower radius of curvature of the lower area of said surface equal to substantially three times that of said median radius and an upper radius of curvature of the upper area of said surface equal to substantially two thirds times that of said median radius said lower and upper radii of curvature joining said median radius tangentially thereto.
