Definitions

  • the ordinary weft-winding machines as hitherto employed, wherein the weft is wound in intersecting spirals upon pirns, are machines wherein the spindles that carry the pirns are arranged in one or more straight rows, rotary motion being imparted to the spindles from a common shaft with the necessary consequence that each spindle has to be provided with gear for throwing the driving mechanism into and out of engagement therewith.
  • the winding of the weft in intersecting spirals is efiected by means of an oscillating weft guide which causes the weft to be wound upon the pirn in an up and down manner.
  • the weft guide for each spindle thus necessitates a separate drive for each cam.
  • the present invention has for its main object to provide an improved weft-winding machine of this type wherein the spindles are arranged circularly so that they can be all driven together by a common wheel located inside the circle of the spindles, and all the weft guides are likewise driven by a common cam.
  • Another object of the invention is to provide improved mechanism for arresting the motion of a winding pirn when the thread, being fed to that pirn, is broken.
  • a further object of the invention is to provide means for automatically stopping the operation of a spindle, when the pirn on that spindle is completely wound.
  • a still further object of the invention is to furnish improved mechanism for insun ing tight winding of the pirns and for winding the pirns progressively from one end to the other.
  • Figure l is a section along the axis of the improved machine.
  • Jig. 2 is a plan thereof.
  • Figs. 3, 4 and 5 which are drawn to an enlarged scale, are respectively a side elevation, a front elevation and a horizontal section 011 the line a-a of Fig. 4:, of a spindle with its accessories.
  • Figs. 6 and 7 illustrate a detail of the means for effecting the automatic discon' nection of a spindle.
  • Fig. 8 is a section of the cone mechanism for effecting the automatic descent of the spindle during the winding of the weft.
  • the weft is wound on a pirn consisting of an open tube of slightly conical shape with its smaller end uppermost, this tube generally ends toward its base in a truncated conical portion, the angle of which is approximately that which it is desired to give to the upper portion of the body of the weft on the pirn during the winding.
  • the pirn is mounted on a rotary spindle.
  • the weft is wound up and down upon the conical base.
  • the weft is guided to the pirn by a weft guide having vertical oscillatory movements of an amplitude equal to the height of said base.
  • the upper part of the body of the weftalready wound on the pirn forms a cone having approximately the same angle as the base, while below the said cone the portion of the body of the weft which has already been com pletely wound, is cylindrical.
  • the framing of this improved machine consists (Figs. 1 and 2) of a bed-plate .l carrying a lower plate 2 and an upper plate 3 connected together by uprights 4, 5, 6, 7.
  • a vertical shaft 8 is mounted between these two plates.
  • This shaft 8 is fixed at its upper end to the cam plate 9 for the weft guide, which is a rotary plate formed with an edge the varying height of which imparts to the weft the vertical oscillations that are necessary to produce the winding in intersecting spirals.
  • the shaft 8 carries at its lower part a driving wheel 10 which produces the rotation of the spindles.
  • This niechanismcomprising the shaft 8, the cam plate 9 and the driving wheel 10, is actuated by means of a leather-covered pulley 11 that drives the cam plate 9 from underneath.
  • Thispulley 11 is mounted on a shaft 12 which is fixed to the framing and along which latter it can move in such a manner as to vary the speed of driving.
  • the shaft 12 is driven by a pulley 13.
  • the spindledriving wheel 10 meshes with pinions 14 mounted in sleeves 16 which constitute oil chambers and are fixed to the lower plate 2 by means of nuts 15 (Fig.
  • a driving sleeve 17 provided with a driving stud 18 engages with its cylindrical lower portion in the pinion 14.
  • T he driving stud 18 is adapted to drop into a semi-circular groove formed in the upper face of the pinion 14, so as to drive when it is in engagement.
  • the spindle 19 is a round spindle extending inside the driving sleeve 17; this spindle is formed with a longitudinal groove 20 in which there engages an internal projection (not shown) of the sleeve 17.
  • the spindle 19 is permitted to move up and down in the sleeve 17 while being continuously rotated by the latter.
  • the disengagement of the sleeve 1'7 and the pinion 14 is effected by means of the tappet 21 on the disengaging rod 22 which is adapted to raise or permit lowering of the driving sleeve 17.
  • the spindle 19 is guided at its upper part by a vertically movable support 23 (Figs.
  • the movable support 23 is guided in a fixed support 27 fixed to the plate 3 and provided with two grooves 26 in which there freely engages a roller 29 mounted on a horizontal journal 28 (Fig. 4) carried by the movable support 23.
  • This movable support 23 is balanced in the usual manner by means of a descending bar 30 to the end of which there is fixed a strap 32 which passing over the guide pulley 31, supports a counterweight 33.
  • the lever carries a sleeve 59, which surrounds the pin 61 and a spring 62 is located in said sleeve and has one of its ends connected to the sleeve and its other end fixed to the stationary washer 63 for the purpose of forcing the cone 34; toward. the lower cone 25 of the pirn 25.
  • the cone 34 by being resiliently forced toward the pirn, has a tendency to cause the pirn to descend, as the thread accumulates upon the same.
  • the inclined portion of the weft cop is always located opposite the point where the weft executes its vertical oscillations that are produced by the edge of varying-heights of the weft guide cam 9.
  • the fixed guide 27 carries a vertically extending post 36, which: is bent downwardly and inwardly over the edge 37 of the cam plate 9.
  • the inner end of the post 36 is bent into hook shape as shown at 52 and the free end of this hook-shaped part terminates in a substantially horizontal hook 35.
  • the weft 35 coming from the upper partof the machine (in the known manner) passes through the hook 35, over the edge 37 and is secured to the cone 25 of the pirn 25. It will be seen that as the pirns 25 are rotated the edge 37 of the rotating cam plate will first raise and then lower the thread 35', so that said thread will be spirally wound on the pirns.
  • the edge of the weft guide cam 9 is formed in such a manner that its lowest point and its highest point shall correspond respectively to the bottom and to the top of the winding cone. But the profile of this edge has a shape suited to the winding which is desired to be produced, and may have either a single incline as shown in the accompanying drawings, or it may have a plurality of ascending and descending inclines of suitable inclinations and lengths.
  • the size of the cop is regulated in the usual mannerby moving the fulcrum 61 of the cone 34 (Fig.
  • the stop motion referred to heretofore serves to produce a stoppage of the rotation of the spindle when the weft breaks.
  • This stop motion is constituted as follows: the fixed support 27 (Fig. 6) carries a pin 38 on which is mounted the stop lever 39.
  • This lever comprises two vertical limbs, namely, an upper limb 39* a lower limb 39", and also I a horizontal limb 39 provided with a countel-weight 4G.
  • the lower vertical limb has a stop shoulder 40 with which the tappet 41 of the vertically movable stop rod 22 is caused to engage by the action of the coiled spring 42 (Fig. 4).
  • This lever 43 carries a tappet 44 against which the lower vertical limb 39 of the lever 39 is caused to bear by the action of the counterweight 46.
  • the upper vertical limb 39 of the stop lever 39 carries at its end a pin 47 on which is fulorumed a lever 48 that is connected by a rod 49 to the weft stop motion device 51.
  • This stop motion device 51 is of angle shape and is pivoted on a pin 50 (Fig. 3) supported by the rod 36, the downwardly and inwardly extending end 51 of the stop device 51 bears against the weft, coming from above, before it enters the hook 35.
  • the stop motion device 51 will rock so that its end 51 will move to the bottom of the hook-shaped part 52 and the inner end of the lever 43 (Fig. 6) will be permitted to drop by its own weight into alinement with the bottom of the cam 9.
  • the bottom of the cam 9 is provided with a horizontally extending inclined plane 53 and when the inner end of the lever 48 falls into alinement with the bottom of the cam, said inner end will be engaged by this inclined plane 53 and this will cause the upper limb 39 to move away from the vertical axis of the machine and thus rock the stop lever 39.
  • the lever 39 rocks, its lower end releases the tappet 41 of the stop rod 22.
  • the coiled spring 42 (Fig. 4) will raise the rod 22 until the tappet 41 contacts with the stop shoulder 45 (Fig. 6) of the lever 43.
  • This rising movement of the stop rod 22 causes its lower tappet 21 to raise the driving sleeve 17, and consequently arrests the movement of the spindle 19.
  • This stop motion mechanism is completed in such a manner that when the pirn has at tained the desired length the spindle will be automatically stopped, andv the spindle which was in the lowest position rises automatically into the highest position; the supporting cone being moved away from it so as to allow of the removal of the filled pirn and of its replacement by an empty pirn.
  • This mechanism is as follows: the movable support 23 of the spindle 19 (Fig. 6) is provided at its lower part with a tappet 54 which in moving down, strikes the inclined arm of the lever 43. This arm is capable of adjustment according to the length of the pirn. This movement compels the lever 43 to rock to ward the right and carry with it the lever 39 by means of the tappet 44.
  • the cone 34 moves away from the spindle 19 by an amount that is sufficient to allow free passage for the pirn which is caused by the counterweight 33 to return into its upper position.
  • the attendant has now merely to remove the filled pirn and to replace it by an empty one. Then he presses upon the upper handle of the stop rod 22 which is sufiicient to replace the handle and the cone 34 into operative position and to cause the spindle 19 to rotate.
  • the cone 34 (Fig. 8) mounted on the angle lever 59, is returned into its operative position by the coiled spring 62.
