Definitions

  • This invention relates to improvements in yarn tension regulators and more particularly the invention relates to release means for regulators of the type adapted for operation inside the pedestal of a textile twisting machine.
  • Certain textile twisting machines are provided with a centrally positioned pedestal carried by a stationary platform which in turn is carried by a rapidly rotating spindle.
  • the centrally positioned pedestal serves as a support over which a bobbin is placed and for maximum eiliciency the pedestal should tbe equal in length or only slightly longer than the bobbin which it is adapted to receive.
  • the centrally positioned pedestal also serves to enclose a yarn tension regulating device for tensioning a yarn end running from or to the bobbin and through the pedestal.
  • tension control regulators While any one of several different types of tension control regulators can be employed in the pedestal of a twisting device such as described above, the type generally considered to offer the best control comprises at least one pair of yarn engaging members between which the yarn is passed. The surface area in contact with the yarn as it passes between the two members is dependent on the distance between the members and so that this may be automatically varied, at least one of the members is generally attached to a pivot arm or the like whereby it is movable with respect to the stationary member.
  • tension regulators suffer from the disadvantage, when placed in a pedestal of the type found in twisting apparatus, that they make threading of the apparatus extremely dicult.
  • the passageway between the two members when in operating position is generally tortuous and cannot readily be penetrated by a threading tool without irst separating the members or releasing the regulator in some other manner.
  • lt is a primary object of this invention to provide improved release means for a yarn tension regulator of the type having a stationary yarn engaging member and a movable ryarn engaging member so that the regulator may be readily threaded-for operation when positioned within the pedestal of a textile twisting machine.
  • annular member adapted to be positioned on the exposed end of the pedestal.
  • the annular member is preferably similar in design to the conventional pedestal cap except that it is mounted for limited movement and carries a lever or the like which extends into the pedestal.
  • the lever is ordinarily out of contact with any part of the tension regu- ICC lator proper but contacts the movable yarn engaging member, preferably through its supporting pivot arm, and moves it in such a manner as to release the tension regulator when the arcuate member is properly manipulated.
  • Figure 1 is a sectional view, taken substantially along the line 1 1 of Figure 2, of a portion of a twister pedestal enclosing a yarn tension control device provided with release means according to this invention.
  • Figure 2 is a sectional view of the pedestal taken substantially along the line 2-2 in Figure l.
  • the numeral 10 indicates the outer housing of the pedestal of a textile twisting machine which may be of the type disclosed in my copending application Serial Number 244,812, led September l, 1951.
  • the outer housing 10 is carried by the package support platform of the twister (not illustrated) and is adapted to t within the central bore of a bobbin.
  • a cylindrical member Positioned partially within the housing 10 is a cylindrical member generally indicated lby the reference numeral 11 and having an exposed extension 12 of smaller diameter.
  • the member 11 constitutes the pedestal proper and serves as a housing for the yarn tension regulating device which is generally indicated by the reference numeral 13.
  • a collar 14 threaded into the upper end of housing 10 bears upon a flange at 15 and serves to properly secure member 11 in position.
  • the tension regulator 13 comprises a stationary member 16 which is rigidly secured by any suitable means such 'as by screw 17 to the cylindrical member 11.
  • a movable yarn engaging member 18 which is .urged toward the stationary member 16 by a spring such as indicated by the reference numeral 19.
  • the spring 19 is so disposed that the force with which member v18 is urged towardmember 16 decreases as the distance between the two members is increased and therefore when a strand of yarn is threaded between the two members, the output tension in the yarn tends to remain substantially constant even with large variations yin input tension as will be readily understood by 'those skilled in the art..
  • the output tension in the yarn can be varied by adjusting the tension in spring 19 by means of ak collar 20 which.
  • the pivot arm 25 is provided with a -bifurcated baseV 29 lthe legs of which terminate as knife edges 30 and 31.
  • the knife edges 30 and31 rest in a pair of notches 32 and 33 infthe Vupper edge-of a cylindricalpl-atform 34 andasl'will be seen thisarrangement permits limited movement of member 19 about the axes of knife edges 30 and 31.
  • a yarn guide cap 35 Positioned atop the pedestal is a yarn guide cap 35 having the shape of a centrally ⁇ bored truncated cone.
  • a support member 41 Secured to the flat base of the pedestal cap by any suitable means such as by a screw 40, is a support member 41 having a pair of downwardly facing knife edges 42 and 43 adapted to rest in a pair of corresponding grooves 44 and 4S in the upper rim of the member 11.
  • a lever arm 46 Extending downwardly into the pedestal from either side of support member 41 is a lever arm 46 having the general shape of a U.
  • the arm 46 is provided with a laterally extending section 47 adapted to contact the inner wall of the member 11 when cap 35 is in normal operating position and a cross bar 48 adapted to contact the pivot arm 25 when cap 35 is turned about its pivot thereby forcing member 18 away from member 16.
  • the laterally extend ing end of lever arm 46 is normally held in Contact with the pedestal wall be a spring 49 attached at one end to the lever arm and at the other end to the inner wall Of member 1l by means of a screw 50 thereby retaining cross bar 43 out of contact with pivot arm 2S when cap 35 is in normal operating position.
  • a threading tool having an attached yarn end is inserted into the central bore of cap 35.
  • Cap 35 is then pivoted on knife edges 42 and 43 which results in cross member 4S contacting pivot arm 25 thereby moving member 18 out of engagement with member 16.
  • the yarn threading tool can then be readily passed between the members 16 and 18 thereby threading the yarn end into its proper path.
  • spring means 49 urges lever arm 46 to return to its normal position with cross bar 48 out of contact with pivot arm 25 and extension 47 resting against the inner wall of the pedestal.
  • Cap 3S is thereby retained in normal operating position until it is necessary to again thread the yarn tension regulating means.
  • said iirst named means comprises a generally U-shaped lever arm extending on either side of said tension regulator and said last named means comprises a spring extending from said arm to the inner wall of said pedestal.
  • Tension regulator release means according to claim 3 wherein said annular member is a centrally bored conical yarn guide.
  • improved tension regulator release means comprising a pedestal cap provided with a pair of knife edges resting on opposite sides of the exposed end of said pedestal, -a lever arm extending from the base of said cap within said pedestal, means carried by said lever arm for contacting said pivot arm when said yarn guide is pivoted whereby said second member is separated from said iirst member, and spring means to normally retain said last named means out of contact with said pivot arms.
  • Tension regulator release means according to claim 5 wherein said lever arm has an extending section urged against the inner wall of said pedestal by said spring means and which contacts said inner wall when the base of said cap is at substantially right angles to the longitudinal axis of said pedestal.
