Definitions

  • the embroidery threads are commonly led from the supply spools about a roughened (usually emery coated) thread roll which, under the control of a brake, permits the threads to be drawn, under suitable tension imposed by the brake, from the spools as the threads are taken up in the movement of the needles to which the threads pass from the thread roll.
  • a roughened thread roll which, under the control of a brake, permits the threads to be drawn, under suitable tension imposed by the brake, from the spools as the threads are taken up in the movement of the needles to which the threads pass from the thread roll.
  • a plurality of thread rolls onefor the threads of one color and another for the threads of the other color or for each other .color if more than two colors are used and instead of applying a separate braking device to each thread roll provision is made whereby either or both of :the thread rolls can be placed, at the will of the operator, in operative relation with a braking device common to both.
  • both thread rolls are placed in operative relation with the common braking device and the threads are therefore drawn oiT under proper tension in the movement ofwthe needles. If, in the production of apart of each design unit,the threads of one color only are to be used, the thread roll which controls the tension of the threads of that color is placed in operative relation with the braking device and the other thread roll is disengaged from the braking device.
  • the threads of the color which is not used are withdrawn from the corresponding needles and provision is made for retaining the ends of such threads in position convenient for rethreading and provision is also made for preventing positively the rotation of the corresponding thread roll so that for the time being no threads of the correspondingv color can be drawn ,from the spools.
  • the provision of means whereby both or all of the thread rolls can be placed simultaneously in operative relation with the common braking devices makes it possible, if so desired, to embroider several different design units with threads of difierent colors or different thicknesses-all under proper tension.
  • the embroidering machine has several groups of thread rolls, each arranged for the control of threads from a corresponding group of spools, provision is made whereby the thread rolls of all groups may be placed simultaneously in operative relation with the braking devices common to the thread rolls of each group.
  • Figure 1 is a view in front elevation of a portion of such an embroidering machine.
  • Figure 2 is a view in vertical section on the irregular plane indicated by the broken line A-B of Figure 1.
  • Figure 3 is a detail view showing some of the parts of the shifting mechanism in a position different from that shown in Figure 1.
  • Figures l, 5 and 6 are detail views on a larger scale illustrating particularly the devices for holding the thread ends in convenient position for the rethreading, Figure 4 being a view in vertical, sectional elevation, Figure 5 is a view in front elevation, and Figure 6 a view in plan, the threads being shown in full lines as engaged with consecutive needles.
  • Figures 7 and 8 are views similar to Figure 6, but showing the threads in different relations with the needles.
  • Figure 9 is a detail view in vertical section of the braking device shown in Figure 1.
  • the frame of the embroidering machine is provided as usual with upright supports, one of which is shown at 1 in Figure l, and with horizontal supporting beams 2. Upon each supporting beam 2 is mounted a frame 3 in bearings 4 of which is rotatably supported a shaft 5. As shown in Figure 1, one at least of the two shafts 5, in this instance the lower shaft is provided with a ratchet wheel 6 with which cooperates a pawl located at 6 so that rotation of the shaft 5 and its associated elements is permitted in one direction only.
  • the hub 7 of the wheel 6 has coopcrating therewith a friction brake of ordinary construction which applies a braking action upon the shaft 5 and therefore upon the thread rolls when in operative relation with such braking device through the shaft 5.
  • a wide gear 8 adapted to be engaged by one or the other or both of two gears 9 and 10 carried by longitudinally movable sleeves 11, 12 which are splined on the shafts 13 and 14 to which are secured respectively the thread rolls 42 and 47.
  • the sleeves 11, 12 are annularly grooved, as at 23, 24, for engagement by pins 21, 22 carried by the arms l8, 19 of a three-armed lever pivoted on the frame, as at 17, and having each a third arm 20, the two arms 20 being connected to move together by a link 49 pivotally connected to the respective arms 20, as at 50.
  • Gne of the three-armed levers 17', l8, 19, such as the lower one of the two, as shown in Figure l, is provided with an operating handle 25 by means of which the operator can shift the gears 9 and 10 to cause both of them to mesh with the gear 8, as shown in Figure 1, or to cause one or the other, such as the gear 10, as shown in Figure 3, to mesh with the gear 8, while the other, such as the gear 9, in Figure 3, is moved into engagement with a fixed detent 28. Movement of the operating handle in the opposite direction to its extreme position shifts the gear 10 out of engagement with the gear 8 and into engagement with a fixed detent 29.
  • the operating handle may be provided with a spring detent of ordinary character, as at 59, for engagement with one of three recesses 59 in the frame 3 for the purpose of facilitating the correct positioning of the operating handle and the three-armed lever.
  • the operating handle may be connected by a link 27, shown in broken lines in Figure 1, with a portion of the automat, that is, the well-known pattern chaincontrolled mechanism for controlling automatically the operation of the embroidering machine, so that the change from the color to the other may be determined automatically.
  • each horizontal frame member 2 is secured a plate 30 on which are supported the spindles 31 which receive the spools 33 of thread of one color, such as blue, for example, and the spindles 32, only one of which is shown, on which are supported the spools 34, only one of which is shown, of thread of the other color used, such as yellow, for example.
  • the threads of one color, such as the blue threads 35 are carried around one of the thread rolls, such as the thread roll 42, and the threads 36, such as the yellow threads, are carried around the thread roll 47.
  • the two groups of thread rolls 42, 4'7 and their asso ciated parts are coupled so that the rolls of bot-h groups may be controlled simultaneously, that is, may be simultaneously engaged with or disengaged from the respective braking devices of the two groups.
  • the shaft 5 of the lower group has secured thereto a bevel gear 52 which meshes with a corresponding bevel gear 53 at the lower end of a shaft 54 mounted in bearings supported by brackets 55 on the frame members 1 and 2.
  • a bevel gear 56 which meshes with -a corresponding bevel gear 5'? on the shaft 5 of the upper group.
  • both of the thread rolls, 42, 47 of each group have their gears 9, 10 in mesh with the gear 8 and are therefore coupled with the braking device common to the two rolls of each group.
  • both blue threads 35 pass about the roll 42 and thence to the needles 3'7 and the yellow threads 36 pass about the thread roll 4'? to the needles 38, all as indicated in Figure 6.
  • the yellow threads are withdrawn from the corresponding needles, the blue threads are threaded into the corresponding needles, the gears are shifted by movement of the lever 25 to its extreme right hand position, the thread roll 42 is coupled to the braking device through the engagement of the gear 9 with the gear 8, and the thread roll 4'? is held positively against rotation through en gagement of the gear 10 with the detent 29.
  • threads 35 and 36 may be passed as usual from the thread rolls 42, 4'? to the needles 3'7, 38 about thread guides 43, 44, mounted as usual upon the frame members.
  • a braking device including a wide gear, gears in operative relation with the thread rolls respectively and relatively movable longitudinally, and means to shift said last named gears into and out of engagement with the first named gear.
  • a braking device including a wide gear, gears in operative relation with the thread rolls respectively and relatively movable longitudinally, means to shift said last named gears into and out of engagement with the first named gear, and detents into engagement with which said last named gears are moved as they are disengaged from said first named gear.
