ARTIFICIAL FIIlAMENT SPINNING FRAME.

applicati mea August 27, i925. serial No. 52,765.

To; all 'whomz't may concern.' o Be it known that THOMAS HARRIS, a citizen in the United States, residing at Woonsocket, in the 'county of Providence and State of Rhode Island, hasinvented certain new and useful Improvements in Artificial Filament Spinning Frames, of which the following is a specification. 0

My invention relates to improvements in machines for spinning strands of artificial fibres, filaments or the like and comprises in combination means to center and'support the up er ends of the spinning boxes thereof during the spinning process.

After the fibre, or filament has been formed in the spinneret or other machine in vthe usual manner, it is led through a glass tube and spun into a cheese inside of a rotating spinning boxe A plurality of spinning -boxes are normally mounted on a frame generally similar to a cotton spinning frame and are v suitably simultaneously' driven. Hitherto as no supports have been provided for the upperends ofthe spinning, boxes l they have ad to be frictionally driven for if positively driven and allowed to be brought to full speed at once, bein top heav they would wobble severelyv an tend to yofl'. Thus it has been' necessary to emplo a friction drive to ease the starting up o the machine. Due to the slip age of the ,friction drive" these machines ave been very inefficient, the spinning boxes be ing driven at varying speeds less than full speed a great portion of the time, and thus not im arting the desired amount of twist per unit length to the filament. By centering and supporting the upper ends of the spinning boxes, I vpermit a positive drive t erefor tobe used, thereby eliminating the necessity for a.. friction drive with4 its consequent loss of efficiency and permitting the machines tobe brought .to full speed almost at once and continuously run without lsli ping. As I preferably also clamp down t e l upper ends of the rotating spinning boxes I provide means to center and support them so they will not wobble or fly ofi' in use. The type of spinning machines to which my invention relates is admittedly the best type of machine for Spinnin artificial silk but prior to my invention t is type of machine as generally been considered inefficient and actually dangerous tothe Workmen..

Employing my invention, the spinning v than formerly, thereby boxes may be rotated at a greater speed l iving a greater amount of twist per unit ength to the fila. ment thanliitherto thought 1possible, thus greatly increasing the strengt of the spun filament.

Employing m invention the size of the spinning boxes t emselves may be increased. In actual ractice I have doubled the diameter of ihe spnning boxes thereby many' times increasing their volume. A further difficulty in employing machines of this type has been the on V'time spent in and vt e labor cost of frequent dofiing. As I greatl increase the size of the spinning box and ecrease the frequency of dofiing the labor cost' of operation is much cut down.

Hitherto due to the small size of the s in@ ning box the artificial silk or other fibre ad to be knotted between each run, `thus providing a lar e number of objectionable knots in the finis ed yarn. Employing my inthe cheese as the radial'distance of the guiding tube v:from the ed e of the cheese is always constant. Hit erto with wobbly spinning boxes this radius 'has been apt to vary, thereby producing objectionablekiuks i in the yarn.

These and such other objects as may hereinafter appearvwill be best understood from a description of one embodiment thereof such as is shown in the accompanying drawin s.

n the drawings, Fig. 1 is a side' elevation of a spinning box employing my 'invention an vincluding the driving means thereof.

.,Fig.2'is a sectional view of-the up er end ofthe Spinninv box with in invention attached, the rais position of the'supporting arm and rotating collar ybeing shown in dotted lines. i

Fig. 3 is a sectional view taken along the line 3-3 of Fig. 2.

Fig. 4 is a sectional View of the hase of the spinning box illustrating inv detail th positive drive 'I preferably employ.

`vention the number of necessary knots and Fig. is a detailed sidefelevation illustrating the positive drive connection beplurality normally employed on this type of spinning frame, with its suitable rotating means andthe means I employ to center and support the upper end thereof. Itis obvious however, that the plurality of spinning boxes 10 are mounted'on the frame and are all simultaneously driven in similar fashion from a common driving shaft 12 which extends longitudinally of the frame and that the means for centerin and supporting the upper ends of eac lrotating spinning box are suitably pivoted to a common shaft 14 which is preferably the usual side bar of th'e spinning frame. Though it is obvious that a plurality of these spinning boxes'are normally simultaneously driven in the frame, in the s ciiication and claims I will refer to one spinning box 10.0111 The spindle 16 extends vertically upWar s from the frame of the machine, and has the spiralv gear 18 for driving purposes Vmounted thereon, whichis driven by the spiral gear 20 suitably mounted onthe driving shaft 12, which as explained is common to the ,driving elements of all the spindles on the frame. The lower end of the spindle may be suitably enclosed within the housing 22. The upper end 24 ,of the rotating spindle, (Fig. 4)A is suitabl centered on the frame by means of the bearing 26. Thou h any type of bearin 26 may be employed preferably employ t e ball race 28, which as shown comprises the usual collar 30 firmly secured to the upper end 24 of the rotating spindle 16 having the circumferential ball receiving channel 32 on the periphery thereof, the cooperating ball receiving channel 34 on the interior of the bearing 26, and the balls 38 mounted in the usual fashion within said channels 32 and. 34 to permit revolution of the spindle 16 therein.

The usual spinning box 10 is mounted on the upper end of the rotating spindle 16. rlhis comprises the usual base 40 and detachable cover 42. As usual the spinning box 10 is of substantially cylindrical shape and is preferably slightly upwardly tapered so that the cover 42 may be readily removed from the base 40 thereof to permit y withdrawal of the cheese 44.

As stated previously the main feature of my'invention is, in combination, means to center, support and align the upper ends of the rotating spinning boxes so that the size of the boxes 10 may be greatly increased as well as the speed of revolution thereof. In combination with said means I preferably employ a positive drive for said rotating spinning box 10, though it is obvious that a frictional drive with-its loss of efficiency still may be employed if desired. To form a positive drive connection between said rotating spindle 16 and spinning box 10 I preferably secure the collar 45 .to the upper end 24 of the rotating spin# dle 16 and I preferably provide the upper edge of said collar 45 with the upwardly extendingsplines 46, (Fig.`5). I. provide the base 40 of said spinning box within the sleeve 48 projecting downwardly 'from the center thereof and I provide onthe lower end of saidsleeve the grooves 50 toreceive the splines 46 of said spindle collar 45 therein to secure a positive drive of said spinning box.

As stated the filament 52 suitably formed as usual in thespinneret orj in thel ',plurality.- t

the gui e 54, (Fig. 2). The fi ament rough the cup 56 on the upper end of the guide tube 54, projects through the lower end 58 thereof, and is spun and radiall Wound into the cheese 44 formed from t e outside inwards within the spin-- ning box 10. The spinning tube 54 is non- Vrotatably held by thehisu'p'port 60. The plurality of tubes 54 and .thesupports- 60 are vertically reciprocated or traversed up and down by the usual means notv shown, to suit'- ably wind the spun filament 52 up and down within the spinning box 1010 form the cheese 44. As statedfthfchief feature of my invention f comprises' in combination means attached to said machine to center and support' the upper endsv of said rotating lllU arms, 62 suitably spaced thereon so thatr there will be one for each spinning:1 box. Ifdesired for adjustment as shownl said arms 62 maycomprise the two arms 62aand 6 2b longitudinally and transversely relatively 'adjustable by means of the bolts 64 thereof. n the outer end of said arm 62 I rotatably mount in `any suitable fashion the rotatable collar 70. Though any means may be provided to suitably mount said rotating collar `70 on the end of said supporting arm 62 I preferably employ the ball race 72, which comprises the cooperating complementary peripheral channels 74 and 76 on the collar 70 and outer end of the arm 62 having the rotating balls 78 therein.

It is obvious that the vertically reciprocal non-rotating guide tube 54 may reciprocate upand down and be contained within the rotating collar 70. To clamp-the rotating collar 7() within the rotating spinning box 10 in thev lon itudinal and transverse slots 66 1115 to secure said rotating spinning box against vertical and horizontal movement I preferably downwardly taper the lower end 8O of said rotating collar and I provide in the center of the to of the cover 42 of the rotating spinning ox 10 the complementary downwardly tapered hole 82. It is obvious that the tapered lower end 8O of the collar 7() securely fitting within the tapered hole 82 in the top of the cover of the spinning box 10 may revolve therewith and that the collar 70 suitably revolubly mounted as explained on the arm 62, clamps down and supports thefupper'end of the rotating spinning box 10. I preferably provide the outer end of the arm 62 with the detachable half 'bearing 84 which may be readily removed if desired. The weighted reinforcing disc 86 may be attached to the to of the cover 42 of the spinning box 10, if ,esired.

After the cheese 44 has been spun to the desired size, in order to doti, it is merely necessary to reciprocate the guide tube 54 to its uppermost position as shown in dotted lines in Fig. 2 and to raise the rotating collarO away from the upper end of the rotating Spinnin box l0 thereby giving room to remove t 1e cover 42 of the spinning box away from the base 40 thereof to permit withdrawal of the cheese 44. After the cheese 44 has been removed, the cover 42 is replaced, the ivoted arm 62 swung down until the tapered lower end of the rotating collar 70 compactly registers in the cooperating tapered hole 82 1n the upper end of the s inning box 10 to securely clamp down sald spinning box 10 when after the machine is started up the end 52 is again fed through the reciprocating tube 54 and a new cheese 44 is spun as usual.

It is obvious that by providin means to center and support the up er en of the rotating spinningbox that have eliminated the kinkly yarn formed by wobbly spinning boxes, that I have permitted a positive drive to be employed, that I have made possible a greater twist .to be imparted to 'the yarn, that I have permitted a much larger box to be employed, thus eliminating the large number of knots formerly necessary, and the cost of fre nent dofiing.

It is understood that my invention is not limited to the specific embodiment shown and that various deviations may be made therefrom without departing from the spirit and scope of the appended claims.
