Definitions
- This invention relates to tension devices for multiple twist types of twisters, particularly for two-for-one uptwisters adapted to tension the thread or yarn proceeding from the stationary package on such twisters into the top or head end of the hollow core of the package on its way to the hollow spindle aligned therewith.
- twist barriers which may also be a tension device for the purpose of preventing insertion of twist directly and immediately into the yarn as it leaves the first tension device. Because the yarn or thread proceeding to the tension device shifts continually about the axis of the tension device, it is possible for the fibers or the filaments to become somewhat disarranged from their normal disposition within the yarn or thread at the point of entry of the yarn into the tension device and this disarrangement, which may involve the looping of one filament or fiber about another in irregular fashion, may be trapped in the yarn at its discharge point from the tension device as the twist imparted by the flier therebeneath is allowed to go back to that first tension device.
- an improved system for preventing the twist from backing up to the first tension device which is not only simple in construction and highly efl'ective in operation, but is quite easy to lace-up.
- the invention comprises the provision of a tension device comprising a freely movable element controlled gravitationally or magnetically and a freely movable spherical element disposed between the tension device and a twisting flier for preventing the backing up of twist to the tension device.
- the spherical element of the twist barrier is also controlled gravitationally or magnetically.
- Figure 1 is an axial section through a preferred embodiment in its normal position on a two-for-one type of upv 2,827,756 Patented Mar. 25, 1958 twister, the twister being more or less diagrammatically shown,
- Figure 5 is a perspective view of a magnet.
- the uptwister comprises a hollow spindle 3 and a hollow passage 4 which communicates with the radial passage 5 in a flier 6 secured rigidly to the spindle for rotation therewith which rotation may be etfected by the whorl 7.
- the spindle is rotatably mounted in suitable bearings in a fixed support 8.
- Spaced bearings 9 and 10 are mounted upon the spindle 3 and support a package holder system comprising a platform 11 and sleeve 12 fitting around the upwardly-extending hub thereof. Any conventional means may be employed for holding the package holder 11 stationary while the spindle and flier are rotated.
- Such means may involve the provision of an eccentric weight carried by the platform 11 when the axis of the spindle is inclined from the vertical or it may involve cooperating magnets or magnetic means, comprising magnetic elements such as magnets on the platform 11 and fixed magnetic element, such as magnets just outside the orbit of the thread balloon.
- the magnetic system may be used whether the axis of the spindle is vertical or inclined to it.
- the package 13 shown in dotted outline may be supported on the holder by slipping its core 14 around the annular projections 15, the latter of which may be formed integrally with the sleeve 12.
- the upper annular projection 15 may be formed integrally on a sleeve 16 the lower end of which is grooved internally to receive a complementary inner annular portion of the sleeve 12.
- the tension device is supported at the upper end of the sleeve 16 in substantial alignment with the passage 4 of the hollow spindle. It comprises a cap 17 having a central bore 18 through which the thread or yarn indicated at 19 may pass. The juncture of the bore 18 with the top of the cap 17 is formed as a portion of a spherical surface to provide a seat for the spherical element or ball 20. This ball rests gravitationally or is pulled magnetically against the seat on the cap 17 and provides the first tensioning of the thread proceeding from the package 13 into the passage 18 on its way to the passage 4 of the spindle.
- a twist barrier in the form of a spherical element or ball 21 which bears against a spherical seat formed about a central bore through the non-magnetic ring member 22.
- the ball 21 is, in this specific embodiment shown, formed of a magnetic material, such as soft iron or steel. It is urged upwardly magnetically by the magnet 23. While the ball 20 may be urged downwardly against its seat by gravitation, particularly when the twister is mounted on a vertical axis, it may also be urged against its seat by a magnet shown at 24, particularly when the twister is mounted upon an axis inclined to the vertical.
- the yarn is tensioned as it passes between the balls 20 and 21.
- the magnets 23 and 24 are held in fixed position within the sleeve 16 and may be spaced apart by a non-magnetic element 25 if desired.
- An annular fastening element 26 whose outer periphery may be threaded to engage internal threads within the lower end of sleeve 16 serves to retain the ring 22, magnets 23 and 24 and the spacer 25 when used.
- the element 26 has a central passage or bore which is gently flared to greater diameter in the zone about the ball 21. The inside diameter of the cavity or recess formed by the enlarged portion of the bore is sufficient to allow the ball to be displaced later ally from its normal central position against the seat under the ring 22 sufficiently to permit the passage of a lacing wire for threadingthe yarn through the system.
- the member .26.
- the ball 21 acts as a twist barrier and toa certain extent applies tension to the thread or yarn so that anyirregularities introduced y t w g g of th yarn 19 about the axis. of.
- Fi u e 2 shows a modification. which differs from. Fi ure 1 in that thefirst tension device is placed, partway Within the sleeve 16' wherein it bears upwardly against phe i lyp s underneath. the ring 7 which is clamped in place'between a magnet 24a supported above the ringand a fitting 28 which is supported above the magnet 23, the ring 22 and the fitting 26.
- the member 28 is bored to form a cup-like receptacle similar to, that within the fitting 2 6 so that the ball 2.0a ,may'be pushed aside by a lacing device such as a wire. While the balls 20a and 21 may be .of the same size, itis. preferred that the ball 21 be smaller in diameter thanfthe upper ball 20a. 7 V V
- the tension and twist barrier unit of Figure 2 is, adapted to be, inserted upon the sleeve 12 in Figure l in Place of the tension and .twist' barrier unit shown therein. Operation of the twister with the unit of Figure 2 it. place is similar to that offthe unit of Eigure'l.
- the unit ,of Figure 2 has somewhat, less tendency to trap and retain foreign particles; such as dirt or lint because oi the .disposition of the ball 2 011, beneath its seat.
- theball *21 and button 29b are of magnetic material and the other parts are of non-magnetic material
- annular members 30:: and 30b are provided one around each of the lower balls.
- the inside diameter of ring 36a is somewhat larger than the diameter of ball 21a to permit the ball to be moved aside sufficiently for a flexible lacing' wire to pass by.
- the ring 30b has a bore whose diameter is somewhat larger than thediameter of ball Zlb o permitthe ball to. be. moved .aside sufiiciently for a. flexible lacing wire to pass on through. Ringfillb ha'sanaunular seat. of.
- spherical curvature to receive ball 21a and a flared surface. extends from the-seat to the inside. wall of .the borein ring 30a. This flared curvature assures that alacing wire will not be caught at the top ofring 3012 during. lacing operations.
- A. ring 300 is provided beneath ring 33112. and has a spherical seat tarball 21b joined by a; flared surface to the inside wall of the ring 30b where the latter rests upon ring 380. The several parts are held. in sleeve 16b between the cap, 17c and an externally threaded holding ring 31..
- the embodiments ofiPigures 3. and 4' are adapted to replace the unit of Figure 1 and. the operation andlacing up thereofi are quite similar.
- the balls andbuttonZllb may be madeof any material desired when they are .to be acted upon gravitationally but when reliance is placedupon a magnet. to urge them toward their seats, they should be. of a paramagnetic material,
- the other parts may be of. any material when magnetsv are not used, but are preferably of non-magnetic. materials. when magnets. are used.
- FIG. 5 shows in perspective oneof the magnets such as, magnet 24 comprising two almost semi-circular segments 4.0 and 41 integrally connected at one end by a bridgingjportijon 42.
- a central bore. 43' is concentric with the cylindrical surface of the magnet. and extends through the interconnecting web 42...
- a sleeve 44 of nonemagnetic material, suchas brass, copper, or the like is fixed Within the. bore 43. and. extends the full depth or height ofj-the. magnet. 1 This sleeve. prevents a. lacing i f m. being deflected. laterally into the transverse slot or groove 45.1 and assures that, the wire continues tendency of theball 21 to, stay upon its seat whereas a angles abrading the yarn.
- the magnet 24 is preferably used, especially when ifjdesired.
