  • Figure 7 is a view partially in vertical section and partially in elevation showing a modified type of tube hold- 2,918,781 Patented Dec. 29, 1959 ICC ing arrangement in accordance with the present invention
  • Figure 8 is a View similar to Figure 7 but showing a still further modification of the present invention
  • Figure 9 is a fragmentary view in vertical section showing the repose position of the holding member of Figure Figure 10 is a view similar to Figure 9 but showing the position of the holding member under centrifugal bias;
  • Figure 11 is a fragmentary view in vertical section illustrating a different type of tube holding mechanism in its repose position
  • Figure 12 is a view structurally corresponding to Figure 11 but showing the holding means in the position which it assumes under centrifugal bias;
  • Figure 13 is a fragmentary view in vertical section of still another modification of the present invention showing the holding means in its position of repose;
  • Figure 14 is a view structurally corresponding to Figure 13, but illustrating the position of the holding means under centrifugal bias.
  • Figure 15 is a view in vertical section of a modified bell-shaped tube for use in an assembly such as that depicted in Figure 8.
  • the numeral 10 designates a twisting spindle of the type used in the ring twisting of threads.
  • This spindle during the twisting operation, is caused to be rotated -at high speed and a ring frame which contains a ring coaxially spaced around the spindle reciprocates lengthwise of the spindle so that a traveler mounted on the ring can lay up the twisted thread on some sort of a spindle carried thread support.
  • the foregoing description isa mere summary of an entirely conventional ring twister.
  • the present invention relates to the support for the twisted yarn and the means by which it is held in position on the spindle.
  • the spindle 10 illustrated in Figure 1 is driven from a belt not shown which acts on a pulley 11, which is keyed or otherwise arranged to rotate with the spindle 10.
  • the pulley 11 is provided at its upper end with an annular externally threaded flange 12 and a coaxial internal cavity 13 defined thereby.
  • An annular groove 18 is cut in the body portion 17 and, centrally, the member 14 is provided with a round hole at 19 lthrough which the spindle 10 passes.
  • a ring 29 of rubber or other similar resilient material occupies the groove 18 and closes off 'the ports in that groove which vare really a part of the dianietrical siot 2li?.
  • the Shanks of the biasing members 25 and 26 being mounted for limited rocking movement about the respective knife edges 23 and 24 can move from a pendant repose position, shown in l Figure 1, to a position partly protruding into the bottom of the groove l and thereby exerting a thrust or bias on the ring 29, see comparatively Figures l and 2.
  • FIG 7 there is shown a modied form of thc present invention which7 while not as satisfactory as the arrangement of the Figures l and 2, particularly for operations at low speeds, is nevertheless of importance.
  • the spindle bears numeral 33 and it is provided with a driving pulley 34 which has a frusto-conical top 3 5 at the base of which there is a marginal groove containing a ring of rubber or other resilient material 36.
  • a marginal flange 37 extends outwardly from the body of the pulley structure somewhat above the belt driving surface indicated at 38.
  • the ange 37 has a groove in it which faces upwardly of the structure as it is depicted in the drawing and in this groove there is located a rubber or rubber-like ring 39.
  • the tube on which the twisted thread is wound bears numeral lil and the base of this tube 40 rests on the top of the ring 39 as can be seen in Figures 7, 9 and l0.
  • a detachable cap il having a centering rim at i2 and a groove directly underneath the centering rim. Within the groove there is disposed a ring 43 of rubber or rubber-like material. The diameter of the ring is so chosen that when the cap and spindle are stationary the ring does not even touch the tube.
  • the rubber ring 39 functions to prevent damage to the tube rims when the tubes are placed over the spindle and likewise acts as a clutch to start the rotation of the tube 4b before the centrifugal force has sufficiently acted on the ring 36 so that it may become the driving element.
  • the construction shown in Figure 8 is in all respects similar to Figure 7 except that the tube, which in this case bears numeral 44, has a bell top which pro,-
  • Figures 7, 8, 9 and l0 are quite satisfactory under most circumstances, if the spindle is rotated at high speed without the thread tube thereover, there is a tendency for the ring 36 to exi pand to such a degree that it breaks under the influence of centrifugal force and therefore has to be replaced.
  • Figures ll and 'l2 there is shown an arrangement whereby this breakage may be prevented.
  • Figure 11 shows the repose position of a ring generally similar in function and location to the ring 36 and Figure l2 shows the position assumed by that ring under ⁇ the l influence of centrifugal force.
  • the spindle bears reference numeral 46 .and .the fragment of the pulley which shows in the drawing bears yreference numeral 47.
  • a flange Alti is provided which corresponds in structure and in function to the flange 37 of Figures 9 and l0.
  • a rubber or rubber-like ring 49 corresponding in structure and in function to the ring 39 of Figures 9 and 10.
  • the upper end of the pulley 47 terminates in a threaded boss 5l) over which there fits a cap 51 which is in the form of the frustum of a cone having an axial bore therethrough for the accommodation of the spindle 46.
  • Fihe base edge skirt or harige of the cap Slt cooperates with a groove 52 in the pulley structure 47 in order to accommodate a rubber or rubber-like ring 53.
  • he overhang of the flange at the bottom of the cap 5l is such as to restrain the ring against extruding entirely from the groove in which it is located when the ring is heavily under the bias of centrifugal force and and no thread tube is in position.
  • a tube bearing reference numeral 54 is shown and it can be seen that the ring is in repose out of contact with the inner wall of the tube. It can also be noted that the groove 52.
  • the ring 53 envelopes the ring 53 for more than 186 of its cross section. It is this envelopment which prevents the emergence of the ring completely from the groove under the bias of centrifugal force. With a tube in position, the ring 53 under centrifugal force assumes the position shown in Figure l2 whereby it may establish a rm and positive driving conriectio-n between the spindle 46 and the tube 54.
  • Figure l5 there is shown a modified type of bellshaped tube which may be used on a spindle as depicted in Figure 8. 1t is to be noted that this tube is provided with a deep rim at S9 for centering, for attaching to the spindle or for the noting of data regarding the thread wound on the tube.
  • the base of the tube of Figure 15 has a thin wall portion at its base designated by reference numeral 60.
  • a twisting assembly comprising a spindle adapted for rotation, a driving pulley for rotating said spindle, a. hollow thread receiving tube mounted coaxially over the spindle with a portion extending over said pulley, means dening a peripheral groove in said pulley, a resilient ring mounted within said groove and adapted to be urged outwardly by centrifugal force into contact with the inner surface of said hollow tube when the spindle is rotated, and means at the mouth of said groove for restraining the ring against complete extrusion from said groove under the bias of centrifugal force.
  • a twisting assembly comprising a spindle adapted for rotation, a driving pulley for rotating said spindle, a hollow thread receiving tube mounted coaxially over the spindle with a portion extending over said pulley, means dening a peripheral groove in said pulley, a first resilient ring of circular cross-section mounted within said peripheral groove and adapted to be urged outwardly by centrifugal force into contact with the inner surface of said hollow tube when the spindle is rotated, a ange projecting from said spindle and defining a marginal groove and a second resilient ring mounted within said marginal groove for supporting said hollow tube, the mouth of said peripheral groove being narrower than the diameter of said first ring.
  • a twisting assembly comprising a spindle mounted for rotation, means defining a peripheral groove in said spindle, a hollow thread receiving tube mounted coaxially over the spindle with a portion thereof extending over said peripheral groove, a resilient ring of circular crosssection mounted within said peripheral groove and movable outwardly into contact with the inner surface of said hollow tube by centrifugal force when the spindle is rotated, and means at the mouth of said groove permitting limited outward movement of said ring against said tube upon rotation of said spindle but restraining the ring against complete separation from said groove under the bias of centrifugal force in the event said spindle is rotated without a tube positioned thereover.
