  • Such mounting means includes an arm 74 pivotally mounted on frame 72 by pivot pin 75 and carrying depressor 68 at its forward end and cam follower 76 at its rearward end for movement between the elevated and lowered positions of the depressor, respectively shown in phantom lines and solid lines in FIG. 7.
  • Depressor 68 has an arcuate shape (best shown in FIG. 4) complementary to spinning rings 22 and normally occupies the lower inoperative position shown in FIGS. 7 and 12, being retained there by gravity. It is raised by cam mechanisms hereinafter described operating in cooperation with its cam follower 76.
  • An arcuate stop surface 88 is provided on the side of supporting frame 72 facing spinning frame 10 for contacting ring base 23.
  • piecing apparatus 36 which are provided in association with assembly 56 for operating it are, with certain exceptions later described, shown and described in US. Pat. No. 3,728,852. Briefly, they consist generally of the following: assembly mounting means including an upright splined shaft 102 and a compound bracket 104, including parallel arms I and 142 mounting assembly 56 upon and for multidirectional movement relative to carriage 38; assembly moving means for imparting movement to the assembly; releasable latching means for releasably maintaining assembly 56 when inoperative in an ele vated position above the maximum elevation of ring rail 34 of spinning machine 10 and assembly stop means including lever l 12 adapted to at desired times engage ring rail 34.
  • the yarn depressor cam follower 76 is operated by means of a pair of cams pivotally mounted on bracket 104. These include a rise cam 77 and a holding cam 78 both pivotally mounted on support plate 79 by a common pin 80 for cooperation with cam follower 76 of yarn depressor 68 as hereinafter explained.

  • operation of the apparatus causes servicing assembly 56 to be lowered until lever 112 engages ring rail 34 and then be advanced from its retracted position of FIG. 10 to its location as shown in FIGS. 2, 4, 5 and 6 for supplying a free end of auxiliary yarn Y from supply bobbin 57 to a spinning frame bobbin 26.
  • arcuate stop surface 88 (FIGS. 4, 5, 6, 7 and 8) mounted upon supporting frame 72 and adapted to engage the cylindrical outer surface of the spinning ring base 23 of the yarn processing delivery of machine 10 undergoing servicing, at an elevation below the path of travel of the traveller 20 about the conventional traveller flange provided at the rings upper edge.
  • yarn release air jet 64 is operated to provide a release jet of air across free yarn zone 73 for removing the free end of yarn Yfrom storage tube 62 and propelling it toward the rotating bobbin 26 for wrapping therearound.
  • FIG. 6 shows said yarn Y in a loop partially removed from storage tube 62, while FIG. 5 shows it wrapped around bobbin 26.
  • a jet of air from yarn wrapping air jet 66 aids in completing wrapping of the free end of auxiliary yarn Y on bobbin 26.
  • the operation of storing and wrapping the auxiliary yarn end around the spinning frame bobbin solely by the use of jets of air from jets fixed on assembly 56 without the necessity of yarn grasping mechanical elements provides uniquely tensioned yarn handling such that the storing is provided in a manner whereby the yarn length extending between the yarn supply and the place of storage is held under sufficient tension that upon executing the step of wrapping about the cop no slack yarn is wrapped or transported (by the air jet) in a slack condition to the cop, rather, the yarn is always kept in a taut, non-slack condition.
  • the present invention provides a simple and effective auxiliary yarn wrapping operation as well as one which is highly reliable, especially by reason of eliminating slack yarn and also by reason of the elimination of mechanical yarn end handling mechanisms and the necessity of keeping them in adjustment.
  • servicing assembly 56 is moved to a partly retracted position, illustrated in FIG. 7, for the purpose of dropping yarn depressor 68, by rotating shaft 102 as explained in US. Pat. No. 3,728,852.
  • the movement of assembly 56 to its partly retracted position causes release of depressor arm cam follower 76 from holding cam 78 and rearward movement of rise cam 77, so that it is free to rise, releasing arm 74 so that yarn depressor 68 falls by gravity from its elevated position (shown in phantom) into its depressed position (shown in solid).
  • the arcuate flange at its free end passes closely adjacent the operating elements of assembly 56 and into overlying engagement with the length of spun yarn, designated Y in FIG. 7, then extending from bobbin 26 into yarn feeding tube 60.
  • Assembly 56 is now again advanced for traveller threading purposes and, as is shown in FIGS. 8 and 9, toward spinning frame 10, by rotation of splined shaft 102 in a clockwise direction, and is halted by abutment of the arcute flange of depressor 6 8 with the cylindrical outer surface of spinning ring 22.
  • the yarn Y extending from bobbin 26 and beneath the depressor flange is caused by the depressor flange to pass closely over and partially about the uppermost flange of spinning ring 22 which supports the traveller 20.to be threaded with such yarn.
  • assembly 56 After assembly 56 has assumed its position of FlGS. 8 and 9, a blast of air then emitted from air jet 70 thereof (FlG. 8) propels traveller 20. in a clockwise direction about the traveller flange of ring 22 and into threaded relationship with the length of yarn Y held as aforesaid by depressor 6,8 in engagement with such flange. Assembly 56 is then returned horizontally to its normal retracted position (FIG. 10) by rotating splined shaft 102 in a counterclockwise direction, which also serves to disengage yarn depressor cam follower 76 from earns 77 and 78. It is then moved upwardly to its raised position as shown in FIGS. 1, 3 and 11.
