IMPERIAL

PATENT OFFICE

; The invention relates to spinning machines with vane spindles and running bobbins, in which the vane spindles and the running coils are separated from each other by special Drives, cords or gear trains can be moved at different speeds.

The device for driving the spindles in these machines is usually with a Friction gear provided, which makes it possible to adjust the speed of the spindle, the The bobbin thickness can be changed automatically, so that the thread tension between the bobbin and wings remain the same for each degree of winding of the coil.

Usually the friction gear is arranged in such a way that it does not directly affect it the spindle acts, but by means of another specially attached for this purpose Wave. .

'The invention now consists in the friction gear on the spindle directly between to attach the driving pulley, which sits loosely on the spindle, and the spindle, so that the movement of the disk is effected directly by means of the friction gear is transferred to the spindle.

This makes the movement mechanism for the spindles opposite to the usual usual friction gear very simplified.

On the accompanying drawing:

Fig. Ι the wing spindle with air coil 'and friction gear in detail and partly in Cut out;

Fig. 2 is the end view and

Fig. 3 is a view from above of the essential parts of a spinning machine, the device showing, by which the disc pressure of the applied friction gear is changed automatically.

As can be seen from Fig. 1, the cord pulley p ^] driving the spindle b sits loosely: on the end of the spindle immediately next to the disk q, which is connected to the spindle by the wedge q * so that it rotates with it, however, can shift according to the length direction of the spindle.

The steel head q ^{2 is} screwed into the hub of the disc q.

To increase the frictional resistance between the disks q and j; ¹ a leather or cloth disc q ^{1 is} attached to one of the rubbing surfaces.

A variable pressure, which increases with the diameter of the bobbin, is exerted on the above-mentioned heads q ^{2 of} all spindles, so that as the thickness of the bobbin increases, so too does the frictional resistance of the friction gear ρ ^l q ¹ q and thus the speed of the spindle increases, _WO: by the tension of the yarn between the wing and the coil at any degree of wrapping of the latter remains the same.

For this purpose the screw spindle if, which is moved from the main drive shaft and the reciprocating movement the thread guide rings by means of a screw without end and a helical wheel connected to an upright shaft, the rotation of which is controlled by a second helical gear is transmitted. On the latter is a spiral

spring attached, which is tensioned by the partial rotation of the wheel.

The other end of the spring is connected by a lever arm to a horizontal shaft which is connected by arms and rods to the upper ends of two vertical shafts in such a way that, as the tension of the spring increases, the latter shafts are slowly rotated and by means of attached arms and webs on the heads of the disks q exert ever increasing pressure.

The spindles b driving cord slices p ¹ to * ³ are set in motion, while the wings E driving cord slices k by the same shaft H of p of a person seated on the main drive shaft H disc ² with double cord running through the cords p ³ and p by means of the Disk j and the cords h and h * are driven.

Bearing chairs B ¹ for the two vertical shafts PP, FIGS. 2 and 3, are attached to the middle stand B of the machine. Each of these shafts carries a lower arm r, at the end of which a vertical web r ^{1 is} attached, which extends to the ends of the two spindles arranged one above the other on the corresponding side of the machine, so that the ends of each web with the heads q ^{2 of} the disks q of these spindles are in contact.

Each shaft P also carries an arm r ⁴ at the upper end; Both arms r ⁴ are connected by rods r ⁵ to the ends of the arms S ¹ S ² seated on the horizontal shaft s . At the opposite end of this shaft sits a longer curved arm s ³ , which is connected by means of a strong spiral spring s ^{4 to a pin s 5} protruding from the surface of a helical wheel Q. The short axis of this screw wheel is held by the chair Q. ^1, which is fixed to the stator B. This chair also serves at the same time as an upper bearing for an upright shaft i ?, which by means of a screw without an end t at its upper end is in engagement with the helical gear Q. At the lower end of the shaft R , a helical gear i ^{1 is} attached, which engages in an endless screw t ^2. The latter sits on the end of the screw K which go to - and serves .hergehenden movement of the thread guide rings in m.

For this purpose, the disk J , which is in contact with these rings on the periphery, sits loosely on the main drive shaft H; the hub of said disc is surrounded by a fork which forms the end of the arm of the slide N. The latter is in engagement with the thread of the screw spindle K by means of a rotatable fork or a nut segment, as a result of which said carriage receives a reciprocating movement in a known manner.

The screw spindle K receives its rotation from the main drive shaft H by means of the standing shaft L, shown in dotted lines in FIGS. 2 and 3. The same is provided at its lower end with a helical wheel η which engages in an endless screw seated at the end of the main drive shaft H. The upper end of the shaft L is connected to the screw spindle K by bevel gears n ² n ³ .

The pressure on the heads q ^{2 of} the disks q to produce the necessary frictional resistance between the surfaces of the disks q and those of the driving cord pulleys p ¹ is, as is evident from the above, brought about by the tension of the spiral spring s * . This spring acts on the long arm s ^{s of} the horizontal shaft s in such a way that the short arms s ¹ s ^{2 of the} same press by means of the rods r ⁵ on the upper arms r ^{4 of} the upright shafts P, the lower arms r of which by means of the webs r ' Press on the heads q ² and press the rubbing parts q and p ^{1 of} the friction gear against one another.

As the work of spinning and winding onto the bobbins is continued, the movement transmitted by the screwed spindle K by means of the turned shaft R produces a very slow rotation of the helical wheel Q. in such a direction that the pressure of the webs r ¹ on the disks q and thus also the friction between q and p ^{l is increased} to the extent that the amount of yarn wound on the bobbin E * increases.

The helical gear Q. does not need more than a quarter to a third of a turn do.

The spindles can be driven by gears as well as cords, in which case the loose pulley p ^{1 is} replaced by a loose gear on each spindle and a corresponding gear train replaces the driving pulley p ² and cords p ³ * . The loose gear on the spindle must have a rubbing surface which must be in contact with the surface of the disk q fixed to the spindle.

Instead of the disks q being connected to the spindles in the manner just described, which allows the pressure to act on the disks mentioned,

Without the spindles being stressed in the direction of their length, in some types of spindles the disks q can also be attached very firmly to the spindles; in this case the required pressure of the disks could be exerted directly on the ends of the spindles and transmitted to the disks by means of the spindles.
