Definitions

  • My invention relates to doffing apparatus for spinning, doubling, twist ng and like machines of the type known as fiyer frames and my present'invention consists in the employment of, deviceswhich I arrange to be actuated by the lifter shaft to secure-the removal ofthe full bobbins from operating position secures the placingof the emptybobbins upon the spindles, the retraction of the empty bobbin holders to allow the raising of the lifter plate and the final advance of the empty bobbin holders intotheir normal positions during the spinning operations.

  • A indicate the two end frames ofthe machine.
  • the lifterplate 5 is arranged to carry out its'vertically reciprocating motions to elfect the building of the coils of yarns on the bobbins in known manner and by well known cam operating devices which actuate the chain (j-that encircles the pulley 7.
  • This pulley 7 is mounted so that it may be detached from the shaft 8 during the doiling operations, while its coupling to said shaft iseifected for carrying-out the usual spinning. process, by devices hereinafter described.
  • a spur wheel 9 Fixed upon the shaft 8 and adjoining the chain guiding pulley 7, is a spur wheel 9 which mesheswith a pinion 10 and this pinion is fixed upon the hub of a hand wheel 11 so that when the operative actuates said hand wheel, 11 he may actuate the wheel9.
  • a clutch bolt 12 which I mount to slide upon one or other of the arms of thewheel 9 so that bythe handle devices 12 said bolt 12 may be made to engage with the-pulley 7 in order to couple same to the wheel .9 to enable said wheel to transmit motion from the pulley 7 to the shaft 8 during the spinning of the yarn and the winding of same in coils upon the bobbins in well known manner.
  • the hand wheel 11 and its pinion 10 are mounted upon a stud 11 supported by appropriate bearings fixed to the end frame A.
  • the lifter plate 5 is connected to and is operated by the usual chain'devices which are made to encircle chain pulleys fixed uponthe shaft- 8 in several positions throughout the length of said shaft 8 in order to meet the requirements of a longer or shorter lifter plate 5 according to the number of spindles in the machine, as is well understood.
  • the bar '16" may be moved longitudinally by its cam 16 and will be supported by the lovers '16 throughout its longitudinal movement.
  • i a On the bar 16" are pivoted two or more levers 16. according to the length of the machine, and the rear ends of the levers 16 are actuated by a spring 16 which keeps or tends to keep said lever-.16 in their advanced positions.
  • the levers 16? are sullicient in number to support another bar 16 which ex tends the full length of the machine in order that the inclinesaon the front edge of said bar 16- may come in contact with the legs of the fiyers 2 somewhat as is shown by Fig.
  • cam 17 Also fixed on the shaft 8 is another cam 17 (of a formation hereinafter described) and this cam 17 actuates the lever 17 (which is pivoted upon the framework of the machine) so that said lever 17, may, by the rod Ill) 1'7 actuate a lever 17 which is fixed upon a shaft 17.
  • slots 0 are formed laterally in said members 18 to span the barrel parts of the bobbins 13 and yet to carry the upwardly projecting flanges (Z which extend from the engaging members 18 to receive and overhang the flanges of the bobbin, also shown'by Fig. 1-4.. v i
  • the cam 18 is arranged to have a part of its surface to occupy a normal position shown'by Fig. during the spinning operations and in said normal position the engaging members 18 may have placed upon them the empty bobbins 13 as is shown by Figs. 14: and 15 while whenthe cam 18 is rotated by the shaft 8 said members 18 may be moved from the said front position .15 where all the bobbins will be held clear of the spindles o and lifter plate 5.
  • This. extension 18 from the rail v18 ,to the rear of the barrels of the bobbins 13 are employed so that they may support the bobbins in a lateral. directionand keep them in proper position, as is shown in broken lines Fig. 15 to enable them to clear or push away the full bobbins as is hereinafter described.
  • the lifter plate 5 is actuated by the known devices hereinbefore explained and is provided with known means whereby the longitudinal bars to which the drag cords 14 aresecured are caused to advance as is set forth. During their advancing move: ments they will earrywith them the bracket 19.
  • This lever 33 is connected to the starting rod 39tl at extends lengthwise thezmachine so that immediately the attendant operates the starting handle 40 to stop the machine prior to dotting, the shaft 40 will oscillate and cause the lever 41 also to oscillate.
  • the rod 39 hence the oscillating of the lever 41 will cause said rod 39 to be moved longitudinally to operate the lever 38 so as to depressthe longitudinal rod 30 thereby relieving all the handle devices which operate the clutches and brake mechanismso that the flyers 2 and their spindles 3 may then be rotated freely.
  • a seriesof brackets 42 which position may be used as a platform for the attendant. to step upon when reaching articles from the upper parts of the machine.
  • a lifter plate for raising and lowering the bobbins upon the spindles, an oscillating shaft for transmitting motion to saidylifter plate, connections from said shaft to said l1fter'-plate,.cam mechanism for automatically operating thelifter plate during the process of building, coupling means for connecting hand operated devices to said shaft, said hand operated devices, bifurcated memhere for laying ported by the lifter plate, a-rail supporting said bifurcated members, a lshaft and connections therefrom to support and operate said rail, lever devices for connecting said shaft to earn mechanism, a cam device for operating said levers to cause the bifurcated members to lay hold of the bobbins and to recede with said bobbins, cam mechanism forremoving coils of yarn from off the spindles when the bobbins have been discharged therefrom,and means for operating said cam devlces.
  • bobbins arranged to take over the spindles of said machines, said spindles, a lifter plate for raising and lowering the bobbins upon the spindles, an oscillating shaft for transmitting motion to said lifter plate, connections from said shaft to'said lifter plate, cam mechanism for automatically operating the lifter.
