Definitions

  • This supplementary resistance must be calculated as a function of the momentary diameter-oi? the windingso as to obtain a constant tension.
  • the present invention relates to a compensating apparatus which acts automatically andthe object of which is to give to the thread a tension which can be regulated duringthe formation oi the bobbin and to automatically maintain this constant tension during the entire operation without its being necessary for worker to intervene for all the spindles or for each, spindle taken individually.
  • the principle of the invention consistsin the various layers of thread on the bobbin, augmenting the brakingaction in such a way that thediameter of this bobbin increases,
  • Figurel is a front elevation or a portion of the machine with the rising and falling rack broken away, and its connections with the apparatus, characteristicof the invention.
  • Figure 2 is a corresponding plan view partly in section.
  • Figure 3 is a detailjview of the paratus in elevation.
  • Figure A is a plan View of the. same.
  • Figure 5 is 'a sectional view or the rising and falling barand of the mounting of the drag weights along-the line 5 5 of Figsvv ure 1.

  • Therising and fallingracl'; or dragtbar in machines constructed according tol this; invention is replaced by continuous and movable bar 1 which is adapted to slide along" driving apithe rising and falling plate ,0 on a roller- 7 track or raceway 2 so as to reduce the resistance due to friction.
  • On this bar 1 is also adapted to slide another bar 3 with or without the interposition of rollers.
  • This second bar 3 is'constantly forced towards the apparatus which operates it,1t;hat is to say towards the left, in Figure l, by means of a compression spring-4: which actsby compression. Conduits shown in Figures, 1 and 5, in e tone.
  • the eyes 13 may be either completely close or they may be split at their upper ends so as to facilitate the putting on of the cord.
  • the cord 15 runs in a horizontal plane, bearing against a certain. part of the circumferenceof the groove in the base of the bobbin, then over the sheave 5 andterminates in a drag weight 17.
  • the member 24 is mounted on round rods 25, 25a which are adapted to slide freely in the sockets 26, 26a of a support 27 and firmly secured by any suitable means to the rising and falling plate.

  • this drum is mounted on ball bearings or bearings of a similar kind.
  • the ring 39 the body of which is connected to the rising and falling plate 0, carries an internally toothed ring 39a which gears into the teeth of the satellite pinion 36, the ratio rovided with a nut and a lock nut and of the transmission of these two gears being preferably 1 to 2.
  • the satellite pinion 36 rotates loosely on a trunnion or stud axle 41, attached to a plate 42, keyed on a shaft 43 carrying on its rear end a gear wheel 44 suitably pinned.
  • the wheel 44 (see Figures 3 and 4) gears into a pinion 45 keyed on the shaft 47 of a worm wheel 46.
  • the shaft 47 rotates in a bearing (not shown) in the support 48 likewiseconnected to the rising and falling plate 0.
  • the support 48 has an upper stirrup or yoke which receives the shafts of a worm 49 gearing into the worm wheel 46.
