nnnn TWIST FLYJEE SPINNING EAGHINE Application filed April 29, 1931, Serial No.
In the American patent application filed on the 3rd April, 1930, under Serial No, 440,999, a double twist dyer spinning machine has been described which efi'ects certain improvements over those of the double twist type in which the thread unwinds from a bobbin situated inside the hall formed by the rotation of this thread, and which is essentially characterized by the whole control w mechanism both of the winding drum carry mg the spun thread, as well as of the thread guide, being loosely mounted on the pirn inside the bell formed by the rotation of the thread drawn from'the outside and, during operation, wound on the inside of the machine, and losing in equilibrium by gravity, by arran ing its centre of gravity below the axis of the said pirn.
The present invention has for its object to make certain modifications in this type of machine principally as regards the mechcausing the traversing movement of thread guide to distribute the thread over the hobhin situated inside the hall formed rotation of the said thread, and its inethod control;
It refers also to a general arrangement of the spindles on the frame of a splnning ma- According to the somewhat complicated device of the thread guide by means of a cam, a rocking lever forked at its outer end and a slide, such as is described in the patent specification above referred to, there is produced an excessive encumbrance in view of the small space available, and after a certain period of usage the play between the difierent membersincrcases and leads to defective operation of the thread guide.
40 Furthermore, as the control cam is always driven at the same speed by the pin it follows that the traversing movement of the thread guide remains constant whatever may be the speed of the roller, Alexandre bobu bin, cop or the like which receives the twisted thread. The traversing movement thus varies according to the speed of the bobbin or the like.
The present invention, which has for its object principally to obviate these varlous 533,671,22116 in France Zinne 20, 1930.
of a fork or yoke journalled in a slide to which is attached an arm carrying the thread guide through which'passes the thread to be distributed over the receiver bobbin.
' 2. The rotation of this double threaded screw and thus the speed of displacement of the traverse is controlled hy the intermediary, if necessary, of a suitable transmission by gearing or otherwise, or by the receiving bobbin of the spun thread, in such manner that the traversing movement remains constant whatever may be the speed of rotation of this bobbin.
3. 0n its exit from the pine, the thread is supported on a fixed part, for example, a bead fixed onthe casing, in order to prevent its contact with the end of the said pirn which is in rotation, and consequently to avoid friction causing the fiatting or glazing of the thread.
4. The control of the sliding changespeed gear is, in view of its greater convenience in manipulation, fitted to the upper part of the casing.
- As regards the general arrangement of the fiyer spindles on the same spinning frame, the principal characteristics are the follow in Y lst. All the pirns of one spinning frame are arranged on one or more difierent stages and staggered in each stage, that is to say, alternately on the right or on the left of the frame, the driving of all these pirns being eflected by means of a single tensioned belt, the runs of which, in the case of two or more stages, are in the same vertical plane,
and which passes. over and under the pirns of each stage.
2nd. Each pirn is provided both for un- 9 winding from. a rotary spool as also for untwisting from a stationary spool, with a system of automatic compensation and braking currently used on certain other t pes of tex- 1 tile machinery such as cop win ers, with a view to regulating by the tension of the thread, the dimension of the ball.
The invention also has in view certain other detail arrangements which will be hereinafter fully set forth, and it has still more particularly in view, under the title of novel industrial products, double twist spinning flyer spindles comprising wholly or partially the application of the above-mentioned devices.
The invention will be readily understood by reference to the following description and the annexed drawings, which description and drawings are given by way of example only.
Figures 1 and 2 are two side elevations partly in section showing the flyer spindle respectively from the side, on which the receiving bobbin is driven, and on the side of the traverse drive.
Figure 3 is a plan view in partial section.
Figures 4 and5 are two Views of the flyer spindle from the-back (cover removed) ,and from the front respectively.
Figures 6 and 7 show in side and front elevation respectively the method of fitting up the flyer spindles and their respective ar-' rangements in sta es.
s in the prior patent the fixed casing 1 the case of two superposed containing the various transmission members is suspended by the intermediary of ball bearings 2 locatedat the end of the pirn 3 carrying a worm 4 continuously meshing with a gear 5 keyed on the shaft 6 of the cone or step gear 7. y
The shaft 8 which carries the sliding pinion 9, is fixed thereto in the sense of rotation by means of key and feather way connection 10 which nevertheless allows the said pinion to move longitudinally of the shaft.
This shaft has fixed at its extremity another pinion 24 constantly, in niesh with a gear 11, and is supported by a pair of elbow levers 12 arranged in thQfOlin of a cage adapted, under' the action of ,the external control 13, to pivot about the axis 14 of the pinion 11. A return spring 15 tends to force this cage continuously in the direction of the arrow (Figure 1) so as to keep the sliding pinion 9 in mesh with the cone gear 7.
From the gear 11 movement is transmitted to the'felt cylinder 16 driving by friction contact the bobbin 17 carried at the end of the arm 18, hinged at 19, by means of a gear train 20, 21, 22 of which the gears 21 and 22, may be interchanged with a view to increasin the number 0 speeds given by the cone 7. e displacement of'the sliding pinion 9 on its axis 8 is effected by means of an external lmob 13 which is adapted to be moved in front of a graduated scale 28 and which is integral with a bent rod 23 fixed to a lining 25 concentric with the sleeve 26 of the said sliding gear 9 and prevented from moving longitudinally of said sleeve by means of a stop 27 'Thus flattening or glazing ery two cross threads connected together at the extremities of the said screw as at 36, to form reversing cams.
In this thread slides a fork or yoke 37 carried by a trunnion 38 engaging in a slide block 39 guided on a rod 40 and fixed to a clutch 41 passing through a slot 42 in the casing 1. An arm 44 which is hinged at 43 to the clutch member 41 carries atits outer end the thread tide 45 into which the thread 46 passes efore being wound on to the bobbin 17.
The aperture 47 made in the casing 1 opposite the exit of the pirn 3 is provided with a stationary bead 48 arranged in the axis of the said pirn, the diameter of the hole in said bead being smaller than that of the channel 49 into which the thread 46 passes. of the thread by contact with the edge of the rotating pirn is prevented.
A semi-circular protector 54 arranged above the worm 4 partially stops oil thrown upwardly by said worm.
As in the prior application the thread passes, in view of its thrown or balloon formation and before its introduction into the pirn, through a guide 50 carried by a disc 51 rotating with the pirn.
A ring 52 situated in front of the flyer spindle and adapted to rock around the axis 53, prevents the thread which is to form the ball, at the moment of starting, coming into contact with the casing or with any of the mechanism associated therewith.
A double set of ball bearings 56, each supporting a pirn 3, are fixed in two stages on superposed cross pieces 57 and 58 of a single machine frame and staggered on each of 1.
these cross pieces, so that the flyer spindles are situated successively to the right and to stage to the left of the frame, and vice versa 2 (Figure 7).
On the 'other hand, in each stage the axes of thepirns of the flyer spindles which are situated on the same side of the frame are slightly staggered with relation to those of the pirns of the flyer spindles of the same stage situated on the other side of the frame.
lit is thus possible to drive all the spindles of the two stages of one frame by means of a single belt 59 passed alternately above and below the pines between the spans of the double ball bearings 56 and stretched by means of an idler pulley 60.
Each flyer spindle is provided with an individual stopping device consisting of a brake block 79 (Figure 6) applied against the pirn 3 by means of a rod 61 supported on an eccentric 62, the rotation of which is controlled by the lever 63.
In the case when the thread supply to the spindle is effected by unwinding from rotary 67 wound round an axis 68 arranged at the top of the corresponding bracket of the said bobbin, the other end 69 of said wire engaging in one of a series of notches in a-toothed sector 70 fixed on the said axis 68.
The wire 67 is, on the other hand, connected by a rod 71 to a resilient brake blade 72, said rod being guided at its lower end in the bracket below the axis of the-bobbin 64, the action of the brake blade on a drum 73 secured to the bobbin being determined by the setting of the end 69 of the wire 67 within the notches of the sector 70.
Gontrar to what is shown on the drawing aligned with said the thread is ide pirn to the t read the aperture in sai pirn and through which on its passa e from the uide, the iameter of f bead being less than that of the pirn, a yoke connected to the thread guide, a double cross-threaded screw engaging with said yoke, the threads of said screw being connected at their ends to form reversing grooves for the yoke, and a casing pivotally mounted on said spindle or pirn and maintained in constant equilibrium by gravity, said casing housing the driving gear for the bobbin, guide and screw.
2. In a double twist flyer spinning machine, a horizontal spindle or pirn, a winding bobbin, a gear train interposed between said spindle and bobbin, one of said gears being slidably mounted to engage with one of a plurality of stepped intermediate gears, a traversin thread guide and a yoke connected to sand guide, a double cross-threaded screw engagln with said yoke, the threads of said screw eing connected at their ends' to form reversing grooves for the yoke, a casing pivotally mounted on said s indle and maintained in constant equili mum by ravity, said casing housing the driving gear or the bobbin, guide and screw, and a control lever for the sliding gear, said control lever terminating above the upper part of the casing. p In witness whereof I aflix my signature.
ALBERT (Figure 7 and this simpl .to increase its clearness, the'two antennae 6 of one bracket, which antennae are .situated respectively to the right and to the left of the frame, should be situated both in the same vertical plane which also coincides with that of the flyer spindles which they have to supply, and which, as above mentioned, are themselves situated back to back in different stages, or, in other words, in the same vertical plane.
On leaving the antennae, the thread 46 passes, before arriving at its flyer spindle, into a guide 74 carriedon an arm 75 fixed on the frame.
Moreover, in the case of untwisting, the bobbins 77 ma also occupy the position shown in dotte line in Figure 6, at the top part of the frame.
It will be understood, as a result of the foregoing description, that the invention is in no way limited to the single method of carrying it-out or to that of its different parts; it covers, on the contrary, all variations of embodiment, comprising wholly or in part the application of. such devices.
at I claim and desire to secure by Letchine, a horizontal spindle ing bobbin driven by said spin e, a traversing thread guide,
a stationary bead axially
