,3 Claims.
,The present invention refers to an improvement in spirmi ng spindles of thekind particularly designed to provide a double twist effect in thefibrebunchesl deliveredby the front drawing trainiof continuous spinning machines.
Similar devices employed for like ends are already known to the art, but these knowndevioes suffer from serious, functional defects which greatly reduce their efiiciency, and which, in spite oftnumereusexperiments madephave not as yet been overcome.
The spindle to which the present application refersis the result ofconstant trials made by experts in the-art and considerable study applied toqactual practice. It was thus possible entirely to eliminate thedeficiencies of the devices known and used tov date;
The constructive. and functional features of the device object of the present invention offer, among others/ the following advantages; Elimination of the traveller or slip ring and, consequently, of the, spinning ring itself; this brings with it theaconsiderableadvantage of enabling the thread to be twisted, or of stepping up the rotation of. the spindlewhich thus can turn at speeds far beyond what is common. For: every simple turnof the spindle, likewise, the twist effect-on theyarnisdoubled, theoutput of yarn, at normal speed of the spindle, is therefore also twice that of, conventional spindles operating at the same speed. As a result oi increasedrigidity andslo-wer rotation of the bobbin, the, yarncarryingcapacityo-f the latter isgreater, without unbalancing the spindle, which considerably favours the output by diminishing the number of runs of the machine. I,
The apparatus similarly offers other important advantages, as will be made clear during the course of the present description.
In order that the present invention may be more clearly understood and readilyput into practice, same will now be described with reference to attached drawings illustrating a preferred embodiment of its principles, said embodiment to betaken as an illustration and in no Way as a limitation upon the invention.
In the drawings Figure 1 is a diagrammatic, and partially, sectional view'of the spindle, showing the particular arrangement of its means and component parts, and
Figure 2 illustrates diagrammatically a constructive variation of a means coupling the spindle and the bobbin.
Like numerals represent like or similar parts throughout the several figures of the drawing.
In the embodiment shown, the double twis t efiectspinning spindle, improved according tothc present invention, is mounted on a tubular base support l, the vertical section of whichis T- shaped. The cross limb l of same rests on-the spindle-carryinsframe 2 of the machine, bearing on a resilient washer or similar means i. This support is suitably fixed to said frame by means of a nut 4 and washers 5.
The spindle itself consists of a cylindrical stem 6 thelower end portion of which is reducedin diameter and which is journaled in a set of ball bearings 1 constituting annular projections; or shoulders provided within thetubular support I. A member 8 revolves on cylindrical member I. said member 8; forming integral part of steinfi, its, purpose being to cause the rotation of the spindle.
A further stem 9 projects vertically from said member 8, It is provided with an axial bore-.-h ole II! whichcommunicates with the outside through orifice l0 provided just above the driving memher 8 and beneath a frusto-conical; plate II'. The upperportion of this plate is provided with a flat flange l2, edge I2 of which engages thread [3 coming from the drawing frame which, after passing through upper eyelet I4, is brought round inclose contact withflange oredge l2 in order to pass through orifice lll' andaxialbore-hole Ill of member 9, andpasses through the open end of said bore-hole andto bobbin I5.
On said stem 9, journalled on ball-bearings IS, a bobbin-carrier l! is mounted, consisting of a sleevethe outside surface of which is cylindrically shaped and provided, close to its lower end, with an; annular fl ange. I'l' serving to support said bobbin l5; when same is frictionally engaged over said surface. Thisbobbin-carrier H can rotate independently of or with the spindle, or can remainstationary when the same rotates. In the first case, the supporting means l6 permits free rotation, uninfluenced by stem or member 9;; on theother hand, a friction means or clutch of any kind It will permit the bobbin carrierto be drivenby the spindle, or remain stationary;
Outside said bobbin IS a stationary cylindrical drum or shell I9, is arranged, mountedon bearings 30 that permit free movement of the spindle and its parts, This drum is, equipped with mea s for guiding the thread, which means consist of an upper eyelet 20 arranged adjacent to and below the plane defining the end of the bore-hole of stem 9, and of a small traveller or slip ring 2| which operates vertically in a guide slot 22 provided therefor in one of the generatrices of the inside of said drum l9.
The slip or sliding action of said small ring or traveller 2I along its guide 22 is provided with an electro-magnet 23 operatively arranged outside of said drum I9 to reciprocate parallel to the axis of the bobbin substantially in front of said guide-slot. The proper tension of thread I3 is obtained by any suitable means, such as a soft-actingbrake or similar arrangement 24.
The thread or bundle of thread supplied by said drawing frame passes through eyelet I4 and, in close contact with the edge I2 of plate I2, through orifice I and axial bore-hole II], on to eyelet 20 and slip ring or traveller 2| from which the winding of bobbin I5 takes place. As at this moment the spindle and its related operating parts I5 and I! is functioning, the thread or bundle of threads is rotatively drawn by the spindle through orifice Ill, its friction againstedge I2 bringing about a slow rotation of bobbin I5 and its supporting sleeve I'I. This permits saidthread to be properly wound on the bobbin and, vdue to the sliding action of travelling ring 2|, vertically moved by the electro-magnet, the correctrposition of the thread in bobbin form being thus obtained. As apparent, drum or shell I9 is stationary. v
The brake means I8 provided at the upper portion of the spindle can likewise cooperate in transmitting the rotatory movement to bobbin I5in this case partially retained by the tensioning effect of the thread caused by member 24, thus bringing about a slow rotatory displacement as the thread is delivered for winding.
The rotatory connection between spindle and bobbin-carrier I! can be established, furthermore, by any known means. One of the many ways of effecting this transmission has been diagrammatically illustrated in iEigureZ. In this device, stemxfi of the spindle has been fixed to a fiat washer 25. This washer is magnetic and its central opening coincides with the axial perforation Ill ofthe stem.
Parallel to said washer 25 a second washer 26, of a larger diameter, has been arranged, properly, centred with regard to aforementioned perforation. This member 26 is controllably mounted on the free end of the bobbin-bearing sleeve H by means of screws 21 which enable a greater or lesser spacing to be obtained between washer26 and magnetized washer 25.
As is evident, when washer 26 approaches magnet 25, the intensity of the magnetic fiux transmitted will increase, and the force of the drive will therefore be greater. On the contrary. when both members separate, the flux will reduce and the drive will slow down, as transmitted by, the spindle to the bobbin carrier. These rotative transmission means can, naturally, replace any other mechanical means employed for similar purposes. As an alternative, the tractive effort of bobbin I5 and its corresponding support can be derived, as already explained, from the friction existing between the rotatory portion of said spindle and the bobbin; or, by the friction between the thread or bundle of threads against the edge I2 of plate II.
All these variations are possible due to the perfect centralization and mounting of the component parts of the spindle and its cooperating members which, in their assembled form, provide the many advantages for which protection is sought after.
The invention as described and illustrated may be clearly understood and no further explanations will be required by those versed in the matter. 7
As the invention herein shown and specified has been described in the manner of a preferred embodiment which is to be considered as an illustrative example and in no ways as a limitation upon the invention, same may be subjected to changes in its construction and details, without thereby departing from its essential nature, asclearly defined in the following claims.
