Thus the An embodiment of the invention is illustrated guide rail will have extension past the pivot I2 by way loi example in the accompanying drawof the rotary member and it is offset with relaings. f Ation to this pivot so that as the shoe is made to Fig. 1 illustrates a device for controlling two slide in the guide rail, by the reciprocation of the yarn guide rods.

'I'he rotary member I3 presents a rounded `edge oil which -it is turned through lapplication -machine drive by ,way of a pair of bevel wheels I 1, I The shaft 20 is pivoted at 23by means cfan angular bearing 24. Projecting laterally from the head of ythe shafty 20 is a boss 22 which has an extension 36 thereon passing through a sleeve 35 onfthe body of the machine. Extension 36 has on its end a nger 31 which is acted upon in positive fashion'by an arm 33 on a shaft 39 for moving the worm 2| out of engagement with the toothed ed'ge of the rotary member I3 when the lever 39 is turned. A coil spring 40 within the sleeve 35 acts in such manner on the boss 22 that it will normally maintain the worm 2| in driving engagement with the rotary member I3. Accordingly as the shaft 39 is turned to and fro in reverse directions the Worm 2| will be moved into and out of driving engagement with the rotary member I3. The shaft 39 may be reversely turned by any suitable mechanism, and especially lends itself to automatic control during the operation of the machine.

In the embodiment according to Fig. 1 the cam I acts simultaneously on two slides or carriages 4. Accordingly" there are also provided two guide rails Il, II having two annular gears I3, I3, which mesh with one another, so that ,the rotary motion imparted by the worm 2| acts also in the opposite sense on the second guide rail To a hook 26 on one of the two gears |3 there is secured a coil spring 25, which is attached at its opposite end -to a hook 4| on the frame ofthe winding machine and which tends to return the guide rails I|, I I into their initial position immediat'ely the gears I3 cease to be acted upon ,by

the worm 2|. If the engagement between the worm 2| and the annular gear I3 is to be broken, a partial rotation is imparted to the shaft 39 (Figs. 1 and 3), the arm 38 then acting on the transverse member or finger 31 of the boss extension 36 and thus rocking the shaft 20 about the pivot 23, whereby the worm 2| is moved out of engagement with the gear I3.

The initial position of the guide rails II, II is determined by a stop 28 (Fig. 4) mounted on a spindle 29, to which there is also secured a pointer 42 co-operating with a fixed scale 34. The adjustment of the pointer 42 is eiected by means of a worm 3|, a shaft 32 and a knob 33, the worm 3| meshing with a gear 30, to which the pointer 42 is preferably attached. The stop 28 projects i'nto the path of rotationof an arm 21 (Figs. 3 and 4) which is xedly mounted on the pivot I2 and accordingly rotates together with the rotary member I3. The arm 21 on the pivot |2is arrested, dependent on the angular position of the adjustable stop 28, when the rotary members I3, after being released by the worm 2|,. are returned into their initial position under the action of the spring 25.

In the arrangement according t the invention there is a neutral, positive or negative transmission of the degree of reciprocation of the carriage 4 to the yarn guide rod 5 dependent on the adjustment, i. e., the degree of inclination, of the oIf thearm 9 of the bell crankLlever is con.

trolled by the guide rail II in the manner illustrated in Fig. 1, the extent of reciprocation of the rod 5 will be greater than that of the carriage 4, as indicated by the extreme positions of the bell crank arms 6 shownI in full and broken lines in Fig. 1. If the arm 9 is controlled by the guide rail in the manner shown in Fig. 2, there results between the two extreme positions of the carriage 4 and of the stud I6 on the rod 5 a considerable reduction in the extent of reciprocation of the latter. During the winding operation the guide rail II ycan be movedA gradually out of the one position, into the other. It is thus possible to vary the degree of reciprocation of the thread during the winding operation between a mini. mum and a maximum. In consequence it is possible to produce on the one winding frame pirns Vof different length and form, such as are illustrated in Figs. 6 to 9, Without the tting vvor removal of any gear parts. If a pirn is to be wound in which the traverses of the thread guide gradually lessen then the guide rail will be initially set in such position as will obtain the desired long length of traverse as shown, for example, by the position occupied by the guide rail as shown in Fig. 1, then by moving the rotary member I3, which is engaged by the worm 2|, in a clockwise direction the traverses of the thread guide are gradually lessened until the guide rail has become moved to occupy an inclined position as shown in Fig. 2, or even beyond this inclined position. Reversely, one may start with short traverses with the guide rail set in inclined position as shown in Fig. 1, and then by moving the rotary member I3, which engaged by the Worm 2 I, in an anti-clockwise direction the traverses of the thread guide may be gradually increased. 'I'he traverses of the thread guide may be maintained at any particular point by maintaining the position of the guide rail, and this by holding the worm, or driving member 2|, in driving engagement with the rotary member which it is engaging, but without rotating the worm.

The simplicity of the device according to the invention and also its reliability in operation will be quite obvious. It is accordingly particularly adapted for use in conjunction with completely automatic winding frames.
