Definitions

  • This invention relates to a twisting spindle 'comprising a hollow central shaft and a support for the supply of the thread.
  • the spindle according to the invention consists of: two sleeves concentric with the hollow shaft and provided with cylindrical shoulders having inclined axes with respect to the axis of Vthe shaft, one of the sleeves being in rigid connection with the support of the thread; two anlnular members rotatably mounted on the said cylindrical shoulders and connecting members capable of maintaining the two annularmembers in two parallel planes; the wholearrangement being such that when one of the sleeves is kept fixed the other one will also be kept fixed, the thread support being thus maintained fixed,
  • V Figure 1 is an axial section of the first form of construction of a spindle taken along the line I-I in Figure 2;
  • Figure 3 is a longitudinal section taken along the line III-III in Figure 2;
  • Figure 4 is an axial section of the second form of construction of the spindle taken along the line IV-IV in Figure 6;
  • Figure 5 is a transverse section taken along the line V-V in Figure 4, and
  • Figure 6 is a transverse section taken along the line VI-VI in Figure 4.
  • the sleeve 1 and consequently also the spool 8 and the cup-shaped member 9 are fixed to a sleeve Il, the latter being formedr with a cylindrical lower extension I2, the geometricall -axis AI3 of which is inclined relatively to the axis of the shaft 2.
  • the spindle rail I supports a sleeve I6 which is fixed thereto and is formed with an upper cylindrical extension I'I, the geometrical axis I8 of which is parallel to the axis I3.
  • a ballbearing I9 On the sleeve extension I'I there is mounted a ballbearing I9 on the outer ring of which there is mounted an annular member 20 which is consequently compelled to turn around the axis I8.
  • the members I5 and 20. are coupled by pins -2I,.2Ia, 2Ib and 2Ic capable of sliding in holes 22, 22a, 22h and 22o provided in the casing 6. Any suitable number of pins may be used four being shown.
  • the ends 23 of the pins are conically shaped and engage in recesses 24 provided in the annular members I5 and 20.
  • the bobbin holder 'I is provided at its upper part with a ferrule 26; a wire yer 2'I is rotatably mounted on the spindle in order to facilitate the lifting of the thread when the spool 8 is unwound. Packings 29 and 39 effect la tight joint for the lubricant and a nut 3
  • a lid 32 forming a baille prevents the lubricant j from escaping from the casing I which is closed at its upper end by a cover 34.
  • the latter is provided with a flange 35 provided with holes 36 and 36a.
  • the thread 31 coming from the spool 8 enters into the upper end of the spindle after having passed through an eyelet in the wire flyer 2'I and leaves the bore 3 in the axis y of theshaft 2, passing through a tubular meml ber 38, an eyelet 39 fand an opening 40 in the casing 6.
  • the thread then passes on to a winding-on spool 4I after having been led through a hole 36 provided in the flange 35.
  • a second thread v43 ( Figure 3) may enter through the lower end of the bore 3 and go to the winding-on spool by passing through a tubular ⁇ member-44, an eyelet 45 andan opening 45 in the casing 6 in such a manner that it becomes assembled with the thread coming from the v spool 8.
  • the casing 6 rotating together with the shaft 2 takes along with it the pins 2
  • the parallelism is due to the fact that several points of these two surfaces are compelled to remain at the same distance, the length of the pins remaining con- ⁇ reservoir V56 provided in the Lframe 53.
  • the axis I8 being fixed in space owing to the fact that the sleeve I6 is fixed to the frame I it followsthat the sleeve II cannot turn Varound the shaft 2 anyv rotation of theisleeve II 4would destroy the parallelism of the axes I3 and i8, which the arrangement of the pins and of the members I5 and 20 renders impossible.
  • the sleeve II being stationary, the bobbin holder 1,v the cupshaped member 9 and the spool 8 which ⁇ are fixed thereto remain also stationary during rotation of the spindle. Owing to the immobility of the feeding spool 8, the thread is given a double twist.
  • ⁇ c in the sockets 2li may be adapted to absorb'the centrifugal forces to which the pins are subjected.
  • the bores 22, 22a, 22h and 22e are 'slightly greater than the pins so as to lallowslight radial ⁇ displacements of the pins 2 I, 2
  • the turbine l5G receives the oil contained in a The oil is delivered by the turbine 5D through'a duct 58 provided in the frame ES--and provided Yin a sleeve 59 ⁇ which carries an inclined ball-bearing-,l It
  • portion of the oil descends along the shaft and after having oiled a ⁇ ball-bearing 62 it arrives in a-cavity 83 from which it returns-tothe reservoir 56 through ducts 5G and E5.
  • A-rotarydeector intothe annular space 5I ascends along the shaft.
  • This turbine vrotates inlacavity 52 provided atthe lower end ⁇ of the frame 53. At its lower end the cavity 52 is closed by 4a member 52 and a stopper 55.
  • the bafe 82 is symmetrical so as to act irrsepective of the rotation of the casing.
  • Thelexcess'o-il-then drops alongthe shaft 5
  • the circulation is continuous during the rotation of the spindle and is automatically-regulated since the outputof the turbine is afunc'tion of the speed and the power consumed is very small.
  • the orifices 90, 98' provided inthe 'casing 12 may serveto balance the casing by compensating for the outlet opening 9
  • Grooves 96 and 91 provided in the upper opening of the frame and 98' provided in the lower portion of the casing likewiser prevent the escape of oil"and ⁇ en'sure a tight joint without introducing detrimental frictions.
  • a rotary conical deectorBS prevents'the thrown-off oil from escaping at the upper part'of its'trajectory.
  • the spindle comprises a regulating Vanddamplng device which facilitates the mounting and compensates for the Wear of the pins'.
