Definitions

  • This invention relates to textile twisting machines of the so-called 2 for 1" type.
  • a machine through a support on which is mounted a stationary cop.
  • the spindle and the cop support or carrier have a central passage therethrough for guiding the yarn unwound from the cop to a flier mounted below the support.
  • the arrangement is such that, when the machine is in operation, it draws yarn from the stationary cop and feeds it downwardly through the spindle to the flier. From this member the yarn runs through a stationary guide above the spindle and then to some suitable take-off or winding mechanism.
  • one turn of twist is put into-the yarn after it leaves the cop and during its travel to the flier, and a second turn of twist is imparted to the yarn by each rotation of the flier.
  • Machines of this type have long been known and they have been used to some extent for coarse work and in a few unusual situations for which it is revolved at a high. speed, it is practically certain to explode. Due to the occurrence or danger of such accidents on 2 for 1 twisters as heretofore constructed; this type of machine has come to be regarded as too dangerous for. practical use in a textile mill.
  • the present invention aims both to insure against the difiiculties and dangers Justdescribed and also to improve the general organization of twisters of this type with a view to making them easy to thread up, facilitating the piecing up operation, and producing a thoroughly safe machine.

  • Fig. 12 is a vertical, sectional view taken on the line l2-l2, Fig. 6, but illustrating the-spindle as equipped with a different form of flier.
  • the machine there illustrated comprises a spindle blade 2 mounted in a spindle base 3 which is supported in a spindle rail 4.
  • Any suitable mounting for the spindle blade may be employed, that shown being a commercial construction commonly used in ring twister spindle.
  • a whirl 5 having a pressed fit with the enlargement of the spindle blade just above the ball bearing provides a convenient means for driving the spindle by the usual tape or belt.
  • a normally stationary support or carrier 6 for the yarn supply body or cop 1. This support comprises a cup-shaped base with an integral, hollow, tapered extension 8 extending upwardly from the central portion of said base, the bore of this extension being stepped to provide internal cylindrical sections a and b in which upper and lower ball bearing units l and I2, respectively, are positioned.
  • the weight of the carrier is supported chiefly by the lower of these units, and for this purpose the shoulder c.
  • Fig. 6, connecting the sections a and b rests on the bearing 12, while the upper bearing chiefly aiiords radial support.
  • This spindle blade and bearing assembly comprises two sleeves 3 and 14, best shown in Fig. 6, both closely encircling the blade 2 and the latter sleeve resting on the former sleeve l3 a washer ii of rubber, or other resilient material, resting on the upper sleeve and a collar I6 spacing the inner race of the bearing l2 from said washer.
  • Another collar l'l spaces the inner races of the two bearings from each other, and a third collar l8 resting on the inner race of the upper bearing supports a-lock washer 28 on which a lock nut 2
  • This nut is threaded on the upper end of the spindle 2 so that by tightening it down, all of the inner races of the bearings are clamped securely to the spindle blade.
  • rubber bushings d are interposed between the outer races of the two bearings and the metal shells with which they are equipped, thus providing cushioning or yielding elements between the spindle blade and the carrier 6.
  • a layer of felt 22,'or other yielding material rests on the upper surface of the car- .rier base 8 to support the cop l and prevent any rotation of the latter relatively to the carrier.
  • the cop is enclosed in a cover 23 which fits frictionally inside the flange of said base so that it can readily be removed when desired.
  • a tension device indicated in general at 24 but which may be of any suitable form, and it continues downwardly through the bore 2', Fig. 6, of the spindle into and through a guide block 25, preferably made of porcelain and better shown in Fig. 11.
  • the block has a vertical hole e to register with the spindle bore 2' and it branches at its lower end to form two lateral outlets leading in opposite directions to the outer surface of the spindle.
  • the lower sleeve I3, above referred to, has openings 1-), Fig. 5, registering with these outlets ee, and the yarn travels through one of them to one of the eyes of a flier 26 of a'novel form. As best shown will be evident from an inspection of Figs. 5 and 7,
  • Two additional horse-shoe magnets 28 and 28' are mounted in cooperative relationship to them, as best shown in Figs. 1 to 4, inclusive.
  • the latter magnets are supported on parts of the machine frame in stationary positions, and the individuals of the two sets of magnets are arranged in reversed relationship; that is, the north and south poles of the magnet 21 are in juxtaposed relation to the south and north poles, respectively, of its cooperating magnet 28, and the poles of the other two magnets are positioned in like relationship.
  • This not only utilizes the mutual attraction of both sets of magnets to their greatest advantage, but it also provides an arrangement in which even a slight angular rotation of the carrier 6 in either direction away from its normal position brings like poles of the magnets 21 and 28 into mutually repelling relationship.
  • An important feature of this invention is the utilization of the repulsion so produced to stop the spindle automatically.
  • a stop mechanism for the spindle is provided in which the magnet 28 is included as a controlling or actuating element.
  • Figs. 1 to 4 it will be seen that the magnet 28 is supported on the upper arm of a bell crank lever 38 which is pivoted at 3
  • the lower arm of this lever carries a pin J, Fig. l, positioned in a slot of a link 33 which is pivoted at 34 to a lever 35 fulcrumed on the bolt 36, Fig. 2.
  • a latch block 31 is bolted to the lower side of the lever 35 and normally engages one side of a similar block 38 secured on the upper surface of another lever 48.
  • This lever is secured rigidly to a sleeve 4
  • a coiled spring 46 acts'on the sleeve 4
  • An adjustable stop screw 48 determines the normal position of the lever 38 and the magnet 28.
  • FIGs. 8, 9, and 10 Another form of stop mechanism for the spindle which sometimes will be found preferable, is illustrated in Figs. 8, 9, and 10.
  • the parts essentially like those shown inFigs. l to 4 are indicated by the 'same but primed or doubleprimed numerals.
  • the spindle structure instead of being mounted to revolve around a stationary axis, as in Fig. 1, is supported on a swinging bracket 50 which .is
  • a latch lever 54 is hooked over a portion 50', Fig. 8, of the web of the bracket 50 and it locks the entire spindle assembly, including those parts carried thereby and those mounted on the bracket 50, in the relationship shown in.Figs.
  • the stop mechanism can be reset merely by lifting the magnet 28' and pushing the whirl 5' back into contact with the driving belt 45. While the mechanism is knocked off, the lever 54 rests in the hole k, Figs. 8 and 9, in the web of the bracket so that upon resetting, it merely drops into its locking position when the magnet has been restored to its normal position. 7
  • any suitable-form of thread tension device may be used in the spindle, provided it is reasonably easy tothread up, produces a uniform drag on the yarn, and can be readily adjusted to give a good gradient of drag or tension.
  • the particular tension device shown magnet 28. This creates a powerful magnetic kick on the latter magnet which will be pracin Fig. 5 comprises av body 55 resting loosely in the top of the tubular extension 8 of the carrier 6 and preferably encircled by a cushioning sleeve 56 of felt, rubber, or equivalent material.
  • this body are mounted two substantially flat metal plates 0 and p having curved ends, and they, are pressed together by a knob or button 58 mounted on a leaf spring 51,-one end of which is secured to said body.
  • This spring is slotted to receive the shank of a screw which secures the button 58 to it for adjustmentlengthwise of the spring.
  • the threading operation is facilitated by the fact that the entire spindle passage through which it is led is substantially straight and This arrangement also is easy to clear in the event of a jam since the thread tensioning device 55 can be picked out of the top of the thread tube 8' instantly, and this fact, plus the open construction at the exit of the-yarn from the spindle, makes it a simple matter to clear out the thread passages completely. Moreover, this construction also applies a minimum of friction to the yam, both during its passage throughthe spindle and also after leaving it, practically all the friction being applied in the tensioning device itself.
  • both forms of fliers are so mounted that they are entirely outside the magnetic field. This is an important factor when a strong magnetic field is maintained to hold the carrier normally in a stationary position. Any conducting element cutting that held will set up eddy currents, and if the conductor has a large continuous area and its speed is high, those currents may easily attain sufllcient value to raise the temperature of such member to a red heat. This difllculty is avoided by the present invention because the path of revolution of the flier is entirely outside or the magnetic field. It should also be noted that all of the magnets are in substantially the same horizontal plane so that any tendency to create an end thrust in either direction is avoided.
  • the use of two sets of permanent magnets, normally located in mutually attracting relationship provides, not only an exceptionally dependable and safe construction but one in which oscillation of the-carrier is prevented.
  • the repulsive efiort or kick then created provides an exceptionally reliable method of-initiating the action of the stop mechanism. This, as above described, is of the greatest importance in a machine of this type because of the tendency which these machines have to run away" and blow up.
