  • the spring is located between a lug 23g on the flange and a stop 23h pinned in the groove.
  • the outer periphery of the ratchet wheel 23d is formed with eight ratchet teeth which provide for indexing or step-by-step rotation of the skein winding shaft 23.
  • the outer end .of the skein winding shaft 23 is mounted in an additional bracket 36. From the bracket 36 and its adjacent bracket 23a are further brackets 31 carrying a Xed pawl shaft 38 on which are located a pair of pawls 3S, 46, urged by coil-springs 39a, y46a located on the said shaft.
  • One pawl 40 hereinafter termed the check pawl, is longer than the other, or holding pawl 3,9.
  • Each pawl is urged at its engaging end, into engagement with the ratchet wheel 23d, by the coil springs aforesaid, the spring 40a for the check pawl being anchored to the adjacent bracket 31 for the shaft and that for the holding pawl being anchored to a collar 4I adjustably secured to the shaft by fa grub screw (not Shown).
  • Each pawl has a tail and adjustably secured on the main shaft 26 is a collar 42 carrying a pair of trip arms 42a, 42h which are adapted successively to trip the pawls 39 and 46, as hereinafter described.
  • a bracket 43 On the arm of the table, and in line with one of the spoked hubs of the skein Winder, is a bracket 43 carrying a cutter shaft 44 which is adapted to be turned through degrees, such cutter shaft being substantially level with the skein winder shaft.
  • On the shaft 44 are fixed tarms 44a carrying a slidable hook 45 of a cutter of 'known type, the relatively stationary blade 46 of which is located on the adjacent arm 44a.
  • the cutter hook 45 is normally positioned level with and on the outside of one of the spokes 25a of the skein holder in the position shown dotted at l45a (Fig. 3) and is adapted to be rotated around the same outwardly to alternative positions 45h or 45C.
  • Such rotation is effected by means of a cam 41 having a face groove 41a and mounted on the end of the main shaft 216 and by a flexible wire cable 48 secured at one end to a drum 49 on the end of the cutter shaft 44 and to an adjustable stud located in ya slot of a cam lever 50 pivoted in a lug at the base of an end bearing bracket 5I for the main shaft 26 and carrying a roller 50a engaged with the face groove 41a of the cam.
  • Return rotation of the cutter shaft is effected by a coil spring 44h.
  • the hook 45 of the cutter is slidably mounted in Ythe arms 44a :xed to the cutter shaft and is actuated by a double grooved collar 52 slidably mounted on the shaft 44, one groove being engaged by a lug 53 on the end of the hook and the other groove being engaged by a stud 54 on one arm of a Ushaped rocker 54a, mounted in a bracket 55 fixed to the arm of the base, the other arm 54h of which rocker has a roller 54C engaging a peripheral groove 41h inthe cam 41 secured to the main shaft.
  • the peripheral groove 41h of the'cam has two lift stages, one being longer for pick up prior to cutting ⁇ and ,the other for cutter opening after severance of the thread.

  • the arm winds the thread as a skein over the hori- Zontal rearwardly projecting pair of spokes 24a, 25a of the skein holder, and at the same time is traversed by the fork I9 under the action of the cam 20 to give a nat skein.
  • the main shaft 26 is rotated a complete turn for the predetermined number of loops to form the skein.
  • the holding pawl 39 When such number of turns have been wound, the holding pawl 39 will be tripped by its trip arm 42a. Meanwhile, rotation of the main shaft 26 will have rotated the worm wheel 23h on the skein holder shaft 23 through 1/8 of a turn moving the lug 23g in its groove to compress the spring 23 f so that immediately on tripping of the holding pawl, the skein holder will be rotated through nearly 1A; of a turn until the check pawl 4U stops such rotation.
  • the flyer may make two or three turns while these next spokes are in their temporary position, as defined by the check pawl, and the initial turns of winding will occur during such period until the skein spokes assume their normal position.

The doffer arms are moved back by their cam in time to be behind the next skein as the skein holder moves to the next position.
  • the skeins, as they are wound, are carried forward through three idle stage positions between the winding and severing positions, and Whilst in such positions, the operative may affix one or more bands 55 (see Figs. 3 and 5) to each skein, according to the speed of the machine and the skill of the operative.
