Definitions

  • This invention relates to textile bobbins, and more particularly to draw twister tubes or pirns.
  • the pirn may be located higher or lower on the taper, depending on tolerances, and may shift vertically during winding, due to the increasing mass of the pirn and yarn carried thereby. This can cause a variation in the yarn location or interference with the winding action resulting in rejection of the yarn.
  • Still another object of the invention is to obtain the foregoing advantages while not interfering noticeably or objectionably with the placement or removal of the pirn.
  • FIG. 1 is a somewhat schematic side elevational view of a pirn and spindle embodying the invention in a preferred form
  • FIG. 2 is an enlarged fragmentary exploded view, partly in axial section on the line II-II of FIG. 3 and partly in side elevation;
  • FIG. 3 is a bottom elevational view of the pirn, looking in the direction of the arrows III-III of FIG. 1;
  • FIG. 4 is a side elevational View as to the spindle, showing the pirn drive end and spindle bearing in central axial section;
  • FIG. 5 is a plan View of the spindle base, with the prn removed;
  • FIG. 6 is a much enlarged and somewhat schematic section on the line VI-VI of FIG. 3, showing the action of one of the resilient gripping iingers;
  • FIG. 7 is a View in elevation as to the spindle and in section on the line VII- VII of FIG. 8 as to the pirn, showing a modification
  • FIG. 8 is a view, partly in section on the line VIII- VIII 0f FIG. 7, and partly in plan elevation.
  • the pirn 1 is shown as seated on the whorl 2 of a spindle.
  • the pirn barrel 3 has a top fitting 4, which may be, for example, of the type shown in prior Patent 2,953,317 and is equipped with a spindle bearing 5 which receives the spindle 6 and with a reinforced ring 7.
  • the last-mentioned elements and their relation to the spindle may be as disclosed in prior Patents 2,625,335 and 3,132,817.
  • the drive end fitting 8 may have the rigid polygonal drive engagement of the two patents just mentioned, with the spindle base.
  • the spindle base comprises a taper 9 for guiding the pirn into place, a cylindrical section 10, which fits in the centering aperture of the drive end of the pirn and is engaged by the resilient gripping means described below, and a polygonal lug 11 for providing a drive connection between spindle and pirn.
  • the barrel 3 comprises a metal tube 12 which seats on a shoulder 13 of the drive end fitting (FIGS. 2 and 4) and a plastic cover 14 which overlaps surface 15 of the fitting.
  • the structure of the drive end fitting 8 may be generally like that shown in Patent 2,953,317 and the cover 14 and its relation to other elements may be as disclosed in Patents 3,095,161 and 3,107,067.
  • the drive end tting has a skirt 17 which fits in a reinforcement 16 in the form of an annular ferrule and is driven into the barrel member 12 with a force fit which holds the end fitting in place (Patent 2,953,317).
  • the drive end fitting has a socket with flats and rounds 19, 20 cooperating with the fiats and rounds 21, 22 of the drive lug 11.
  • a further cylindrical fiange element 23 which has a cylindrical inner surface fitting around the spindle base section 10.
  • the flange element 23 of the pirn and the base section of the spindle together comprise centering means for the pirn and the spindle.
  • the upper edge of flange element 23 is slotted to form spring tongues 25, shown as nine in number, separated by gaps or slos 26.
  • the tongues 25 have comparatively thick heads 27, supported by the gradually thinning sections 28 on the shafts 29.
  • the invention is applicable to pirns or bobbins of different sizes and proportions and in which the parts are made of a variety of materials.
  • a bobbin of one and three quarters inch diameter and proportioned as in FIG. l will be discussed by way of example.
  • the tube 12 will be assumed to be steel, although aluminum and other materials may be used, and the end fitting 8 will be assumed to be nylon, although other materials may be used, such, for example, as A.B.S. resin or metal.
  • the clearance between fiange element 23 and spindle base 10 may be about 0.002 (radial), while the overhang or projection of the heads 27 of the tongues 25 may be about 0.020 (radial).
  • a deflection of thel spring tongues 25 of about ten times the permitted movement of the drive end from centered position may be had.
  • the resistance to relative movement due to the friction between the spring tongues and the spindle base 10 is large, being comparable to the spring force opposing the movement, and a large damping effect is provided, eliminating any tendency toward vibration.
  • the rate of the spring tongues and the force exerted in centered position can be regulated very closely by varying one or more of the following factors:
  • the moment of inertia of the tongue cross section depends very much on the degree of circumferential arching, so that by decreasing the number of tongues and correspondingly increasing the angle subtended by each tongue, the ⁇ total spring force can be very much i11- creased.
  • the spring tongues have been shown as extending upwardly from the upper edge of a centering aperture which is itself located above the drive connection between pirn and spindle, the tongues may also extend downwardly ⁇ and be positioned either above or below the centering aperture or drive connection, as the arrangement of elements may make convenient.
  • the tongue gripping action may be supplemented by additional spring elements, as, for example, by a split ring or garter spring, surrounding the tongues and pressing them against the spindle base section.
  • the spring gripping action may also be applied at the upper spindle bearing point, as shown in FIGS. l, 3 and 4.
  • the spindle bearing member 5 has a flange element 23 fitting around the spindle blade 6 and resilient spring tongues 25 which grip the spindle blade. These tongues are defined by slots 26 and have thickened tips 27', tapering sections 28' and shanks 29. Since the structure and function of these parts is the same as already described with reference to the similarly numbered parts in the drive end fitting, no further description is required.
  • the skirt 17' of member 5 may simply fit in the barrel member 12, as shown, or it may also be provided with a reinforcement like the member A16.
  • FIGS. 7 and 8 show a modification of the pirn structure.
  • the spindle base has a dog or key drive, rather than a polygonal drive, and the pirn drive end is modified accordingly.
  • Spindle base section 10 has a pair of diametrally opposed dogs or keys 30, which engage in apertures or recesses 31 in the drive end fitting.
  • the pirn drive end has a centering aperture, formed by the tubular flange 33, and a skirt or outer tubular flange 37, which fits into reinforcement -ring 36 and is force fitted into the barrel.
  • the similarity of the structure as thus far described to that of FIGS. l to 6 will be apparent.
  • the remainder of the structure may also be the same as in earlier figures, spring tongues 25 being formed on the drive end itself as shown in FIG. 2.
  • FIGS. 7 and 8 a modified form of resilient gripping means, the inner flange 33 terminating above centering aperture and the spring tongues 35 being formed on the element 36, which fits the skirt or outer flange 37 for holding the drive end in the barrel, as the element 16 fits flange 17, previously described.
  • Element 36 is extended radially inward and formed into spring tongues 35, separated by cutouts 38 and which engage the spindle base 10 in the same way as the tongues 25.
  • Element 36 being metal, further control of spring rate and pressure can be had, as also variation of fricton coefficient, where desired.
  • FIGS. 7 and 8 can ⁇ be substituted for the corresponding structure of the polygonal drive end or upper bearing elements of FIGS. 1 to 6.
  • the pirn of the invention is placed on the spindle and removed in the same manner as heretofore, the pirn being pushed down on the spindle and twisted so as to engage the rigid drive elements, and the pirn being removed by lifting it off the spindle manually.
  • the spring action and friction against the spindle base serve merely to absorb the shock of placement of the pirn.
  • the effort involved in lifting the weight of pirn and yarn is not altered appreciably by the frictional resistance of the spring tongues engaging spindle Ibase section 10.
  • a spindle and pirn carried thereby, cooperating drive means on the spindle and pirn for driving the pirn from the spindle, and centering means on the pirn and spindle for limiting lateral relative movement thereof, said centering means ⁇ comprising a cylindrical base section of the spindle and a cylindrical element of the pirn disposed about the spindle base section, the inside diameter of said cylindrical element of the pirn being greater than the outside diameter of said cylindrical base section of the spindle so as to provide clearance therebetween, the cylindrical element of the pirn being provided with a plurality of circumferentially spaced spring tongues having enlarged inwardly project ing heads that ⁇ bear resiliently against the spindle base section thereby opposing lateral relative movement away from centered position.
  • a pirn having a bearing for tting a spindle and a drive end for seating on a spindle whorl and providing a drive connection thereto, characterized by a socket for engaging with a spindle base member to form a rotary drive connection, in combination with an internal axially concentric cylindrical ange element in the pirn for centering the pirn about a cylindrical base section of the spindle, the inside diameter of said cylindrical element of the pirn being greater than the outside diameter of said cylindrical base section of the spindle so as to provide clearance therebetween, and a plurality of spring tongues having enlarged heads extending radially inward of said ange element to engage and grip the cylindrical base section and hold the pirn to the spindle against vibration.
