Definitions

  • This invention is concerned with such devices for twisting textile and other yarns, threads and filaments, as are adapted to impart to the yarn or the like more than one turn of twist for each revolution of the device, an effect which is achieved by drawing the yarn or the like from a package down through a hollow spindle and outwardly and upwardly therefrom to form a balloon about the package and rotating the loop so formed.
  • the rotation of the loop has been achieved through the medium of auxiliary mechanism associated with the package support, or by applying gravitational or magnetic force to the package to prevent its rotation with the spindle.
  • the object of the present invention is to provide an improved form of twisting device in which the necessary relative rotary movement between the twisting element or spindle and the yarn package is obtained by means providing either a positively driven rotation of the package in the opposite direction to that of the twisting element, or a substantially stationary condition of the package during the twisting operation.
  • a twisting device in accordance with the invention comprises a hollow spindle and a flyer operating in conjunction therewith to lead the yarn or the like outwardly in loop form from the bore of the spindle as drawn from a package mounted on the spindle and rotatable independently thereof, and means for imparting to the package support a rotation of algebraically less speed than that of the spindle, said means depending upon the rolling contact of a rotor, which is arranged in driving relationship with the package support, with a non-rotary circular race or track the axis whereof is eccentric to the axis of the rotor.
  • Such an arrangement enables the speed of rotation of the package to be controlled, reducing the risk of damage to the spindle by an unbalanced package and preventing variation in the amount of additional twist introduced into the yarn or the like.
  • Fig. 1 is a vertical section of a complete spinning um't
  • Fig. 2 is a similar view of a modification thereof
  • Fig. 3 is a similar view of a further modification.
  • the spindle l is mounted in two spaced anti-friction journal bearings, i. e. a bearing 2 at or near to its mid-point and a bearing 3 at its base. Said bearings are supported in a tubular bolster 4 apertured at 5 to provide access for a driving tape or band 6 to a spindle wharve I located between the bearing points 2- and 3.
  • the bolster 4 is extended upwardly in the form of a bowl to provide by its upper rim 8 an annular internal race l0. co-axial with the main spindle axis and surrounding the rotor hereinafter described.
  • the upper part II of the spindle I constitutes a bearing member upon which a yarn package or bobbin 1! is carried by means of a plate l3 having a central hub l4 enclosing anti-friction bearings I5 and I6 by which it is mounted on said bearing member II with capability of rotation independently of the spindle I.
  • the spindle l carries a radially projecting flyer or yarn guide l1, and the arrangement is such that a yarn to be twisted (indicated by the numeral I8) is led from the package l2 through the inwardly turned upper extremity of the package tube l9, down an axial bore 20 in the upper part II of the spindle, through an aperture 2
  • said crank 22 carries an anti-friction bearing 23 upon the outer element of which is mounted a rotor 24 of disc formation, the periphery whereof is located at the same level as the annular internal race ll! of the bowlshaped part 8 of the bolster 4.
  • the radial dimension of said rotor disc 24 is such that its periphery makes contact with the said annular race I0 at one side; diametrically opposite said point of contact the space between the rotor disc 24 and the annular race I0 is just suflicient to accommodate the flyer or yarn guide I! projecting upwardly through the same.
  • the revolution of the fiyer H inserts twist in the yarn l8 passing down through the hollow spindle from the package l2. Due to the eccentric or orbital motion of the crank 22 the rotor 24 is constrained to move with rolling contact about the surface of the annular race I0, resulting in the rotor 24 revolving in the direction opposite to that of the spindle rotation.
  • the frictional contact between the plate l3 and the rotor 24 may be relied upon to communicate the reversed driving motion to the package l2, and if necessary suitably prepared friction surfaces may be provided on these elements to transmit the drive, any desired speed of the package which permitting it to assume a gyratory-motion as the spindle revolves.
  • the package support is mounted by means of anti-friction bearings I5, [6 upon the bored upward axial extension H of the spindle, and the plate-portion l3a of said support constitutes a space between the rotor 31 and the race 38. leading it outside the spindle to a fiyer 4
  • the package support 36 is made of resilient material, in order that it may absorb vibrations due to the gyration of the shaft 35 and the parts supported thereby.
  • a twisting device for twisting yarns, threads or filaments comprising, in combination, a hollow spindle, a, package support surrounding the spindle, a fiyer, fiyer driving means, the hollow rotor which is arranged to make contact with the "annular internal race Illa of ,the bowl-shaped underside of said rotor plate 13a. to a position in which it will guide a yarn I8 which has passed down through the bore 28 of the spindle, outwardly through the space between the rotor I and the internal race lfla of the bowl-shaped member 8a diametrically opposite to the point of contact between these members.
  • the revolution of the fiyer i! with the spindle I serves to rotate the loop of yarn l8 which is drawn from the package through the bore 28 of the spindle and thence outwardly and upwardly to the balloon. Due to the eccentric relationship which exists between the rotor-plate 13a. and the annular race Illa as the latter is caused by the aforesaid gyratory motion due to the crank 22 to roll around the periphery of the former, the resultant effect is to rotate said rotor-plate 13a in the direction opposite to that of the spindle rotation.
  • the spindle consists of a cylindrical tube 28 which is supported by means of two spaced anti-friction bearings 28 and 30 upon a vertical axle 3i which is fixed in the spindle rail 32.
  • the lower part of the outer wall of said tube 28 constitutes a wharve by means whereof the spindle is driven in the customary manner through the band or tape 6.
  • said spindle tube 28 is provided with spaced anti-friction bearings 33 and 35, in which is rotatably mounted a. hollow shaft 35 which carries the package support 36 at its upper end and which terminates at its lower end within the hollow interior of the spindle 28 in a hollow conical member 31 which constitutes the rotor.
  • the said bearings 33, 34 are slightly oii'set with respect to the rotary axis of the spindle 28, in such manner that the revolution of the spindle 28 produces acorrespondingly gyratory motion of said shaft 35 and the rotor 31 fixed thereon.
  • the said gyration is utilised to produce a rolling contact between the inner surface of the hollow conical rotor 31 and a fiat circular table 38 which is fixed on the upper extremity of the aforesaid stationary axle 3
  • the spindle 28 is provided with an aperture 40 which forms a guide for a yarn l8, which has been drawn from the package l2 down the bore of the package support shaft 35 and through the spindle directing the yarn from the package to the flyer and the flyer directing the yarn to define a balloon which envelopes the package, the package support and the upper end of the spindle, and a mechanical reduction train connecting the fiyer driving means with the package support to control the rotary motion of the package support, limiting it to a lesser value algebraically than that of the fiyer, said train comprising a nonrotary, circular race member, a rotary member having driving relation to the package support, said rotary member being eccentric to the race member and having rolling contact therewith, and means driving the axis of one of said members in a circular path about the axis of the other.
  • a twisting device as set forth in claim 1 in which the rotary reduction train member is disposed eccentrically with respect to the spindle and the non-rotary member is disposed concentrically with respect thereto, both saidmembers being distinct from the package support, the package support being guided for rotary movement concentric with the spindleand resting frictionally upon said rotary member.
  • a twisting device as set forth in claim 1 in which the non-rotary member of the reduction train is mounted eccentrically with respect to the spindle and is orbitally driven by the spindle, and the rotary member of said train is concentric with the spindle and forms a unitary part of the package support.
  • a twisting device as set forth in claim 1 whichincludes a bolster that provides pivotal support for the spindle, said bolster having an upper annular extension which forms the nonrotary member of said reduction train.
  • the non-rotary member extending concentrically around the spindle and in rolling contact with the rotary member at a single point, and the flyer being mounted on the spindle so that it projects upward through the space between the rotary and non-rotary members, substantially opposite the point of rolling contact.
  • rotary member constituting the package sup-. port and having rolling contact at a single point with the inner face of the annular portion of the non-rotary member, and the liver being mounted on the spindle to project upward between the rotary and non-rotary members substantially opposite the point of rolling contact.
  • a twisting device for twisting yarns, threads or filaments comprising, in combination, a cylindrical tube, a fixed support on which the tube is mounted for rotation about a vertical axis, said tube including a driving wharve portion, a
  • Y 6 circular race table on said fixed support within the tube.
  • a package supporting shaft eccentrical 1y mounted in the tube, said shaft having a hollow conical rotor unitary with 'it, the interior surface of the rotor being in rolling contact with the racetable, the shaft having a hollow bore through it for conducting the yarn from the package, and the tube having a lateral aperture substantially opposite the point of said rolling contact. and a fiver fixed on the tube in proximity to-said aperture, the construction andiarrange- I ment being such that yarn may he led from the v tube bore through the space between the rotor and the race table and outwardly through the lateral aperture in the tube to the flyer.
