Definitions

  • My invention consists in providing braking means in connection with the spindle of the flyer which are thrown into operation after throwing the whole machine out of operation and when the moment of the motor falls below the tension of the threads, and when the thread is applied to a single spindle while the other spindles continue their operation.
  • FIG. 1 is a sectional elevation showing a fiyer and its driving mechanism
  • Fig. 2 is a sectional plan view taken on the line 2'2 of Fig. 1,

  • Fig, 3 is a sectional elevation showing another modification
  • Fig. 4 is a sectional plan view takenon the line 44 of Fig. 3,
  • Fig. 5 is a partial sectional elevation of the fiyer shown in Figs. 3 and 4 and illustrating the electrical operating mechanism thereof
  • F 1g. 6 is a sectional plan view taken on the line 6-6 of Fig. 5, and
  • Fig. 7 is a similar sectional plan view showing a modification.
  • the mechanism comprises a casing 1 and an electric motor having a stator 2 and a rotor 4.
  • the windings have been omitted for clearness sake.
  • the rotor is secured to a vertical spindle 3 mounted in anti-friction bearings 5 and 6.
  • a cap 7 is secured which is formed with recesses 71 receiving brake blocks 8 acted upon by springs 9.
  • the inner faces of the said brake blocks carry linings 10 having a high coefiicient of friction, which linings are adapted for frictional engagement with a flange 11 provided on the top wall of the casing 1.
  • the hub of the disk 7 clamps the inner race ring of the anti-friction bearing 5 in position and provides a protective shield for the said anti-friction bearing.
  • the brake blocks 8 have the function of weighted bodies exposed to centrifugal action.
  • Fig. 264 I have shown a modification in wlnch the brake blocks are in the form of levers 13 rockingly mounted on pivot bolts.
  • the springs 9 are embedded in sockets 131 of the levers 13.
  • a spider is fixed to the spindle 3 between the motor and the flyer 50, the said spider comprising a hub 16 secured to the spindle and arms 17 carried by said hub.
  • an electromagnet .18 mounted within the bottom part of the casing 1 which electromagnet comprises an annular yoke 19 and field windings 18.
  • the d1stance between the field poles of the yoke is equal to the distance between the arms of the spider.
  • the electromagnet is automatically energized by means of contacts subjected to centrifugal action when the number of revolutions of the motor is reduced below a certain limit, the said contacts closing the circuit of the windings of the elect-romagnet, while the said circuit is broken when the number of revolutions rises above the said limit.
  • the said contacts have not been shown in Figs. 3 and 1, but the electrical construction will be understood from Figs. 5 and 6.
  • the annular yoke 19 of the electromagnet carries two annular contact members 20 and 21 separated from each other and from the yoke 19 by insulating material (not shown in the figures), so that the current cannot pass from the rings 20 and 21 to the yoke 19.
  • a contact 22 is secured, which is likewise insulated relatively to the yoke.
  • the outer ring 20 and the lower ring 22 are connected respectively with leads 23 and 2 1.
  • the rings 20 and 21 are adapted to be elec trica-lly connected by a contact piece 22 mounted on an arm 26 made from elastic and insulating material such as whale bone, wood, bakelite and the like. As appears from Fig.
  • the said ring is curved and it is fixed to the shaft 3 by means of an eye 17.
  • the ring 21 is electrically connected with the windings 18 mounted on the poles of the yoke 19.
  • the said windings are either connected in shunt, separate leads being provided for connecting each winding with the ring 21, or all the windings are connected in series, a single lead 28 being provided for connecting the ring 21 and one of the windings, so the wind-' ings are successively connected with each other while the last winding is connected by a lead 29 with the lower ring 22. If the windings are connected in shunt leads are provided for connecting each winding with the lower ring 22.
  • windings 18 are connected in series and for clearness sake the leads connecting successive windings have been omitted.
  • the curvature of the arm 26 must be such that the contact piece 25 cannot be brought by centrifugal action above the rings 20 and 21 for electrically connecting the same, but that it is rocked beyond the same at high velocity, so that the electrical connection is broken.
  • the contact piece 25 engages the rings 20 and 21 at a certain number of revolutions thus electrically connecting the same.
  • the current flows from the lead 23 to the ring 20, the contact piece 25, the ring 21, the lead 28, the windings 18, the lead 29, the lower c0ntact ring 22 and the lead 2 1.
  • ⁇ Vhen further increasing the number of revolutions the arm 26 is further rocked into position for setting the contact piece 25 beyond the inner ring 21, thus breaking the connection between the rings 20 and 21 and interrupting the current.
  • Fig. 7 I have shown a modification in which in lieu of the curved arm 26 a stem 30 is provided which carries the contact piece 25 and is slidable in a sleeve 31 fixed to the shaft 3 by means of an eye 2. WVithin the sleeve 31 there is a spring 32 engaging the head formed at the inner end of the stem 30 and bearing with its outer end on an inwardly directed flange of the sleeve 31. ⁇ Vhen starting the electromotor the contact piece 25 is thrown outwardly by centrifugal action, as is shown in Fig. 7 in dotted lines, thus connecting the rings 20 and 21. Then further increasing the number of revolutions and the centrifugal force the contact piece 25 is further thrown outwardly thus breaking the connection between the rings 20 and 21.
  • brake blocks are mounted 011 levers adapted to be rocked by springs into releasing position and acted upon by an electromagnet throwing the same into braking position or vice versa, suitable means being provided for controlling the supply of current to the electromagnets.
  • a flyer In a spinning apparatus, a flyer, a motor for driving the same, a brake block rotatable with said fiyer and movable in response to centrifugal action out of braking position, and yieldable means counter-acting said centrifugal action.
  • a flyer In a spinning apparatus, a flyer, a spindle carrying the sm a m'o'tor' 'on'said spindle, a casing enclosing said motor, a disk on said spindle above said casing, and brake blocks on said disk controlled by centrifugal action and mounted for movement thereby out of braking position.
  • a flyer In a spinning apparatus, a flyer, a spindle carrying the same, the motor on said spindle, a casing enclosing said motor formed at its top with an upwardly directed flange antifriction bearings in which said spindle is rotatable, one of said anti-fricton bearings having its outer race ring mounted on said flange, a disk on said spindle above said casing in position for clamping the inner race ring of the bearing having its outer race ring mounted on said flange and formed with a rim embracing said flange, brake blocks radially movable on said ring and adapted for braking engagement with said flange, and springs tending to force said brake blocks into braking engagement with said flange.
  • a flyer In a spinning apparatus, a flyer, a motor for driving the same, an electromagnetic brake for braking said flyer, and a circuit make and break device controlling the speed of the flyer and operable by centrifugal action to render said brake inefi'ective.
  • the combination with a flyer of a motor for driving said flyer, means for retarding rotation movement of said flyer, and means operable upon reduction of the speed of the flyer for rendering said flyer retarding means effective.
