CROSS WINDING- FRAME Application filed February 25, 1930, Serial No. 431,290, an

The invention relates to a regulating and stop mechanism for cross winding frames having a weight-loaded tnread guide frame and intended to wind quite soft bobbins, e. g.

,5 for dyeing purposes.

In order that the invention can be more readily understood, a preferred embodiment of the same is illustrated by way of example in the accompanying drawingsin which Figure l is a front view of the mechanism,

Figure 2 a corresponding side view, and

Figure 3 is a detail thereof.

Referring to these figures, 1 denotes the thread guide shiftable along the spool or bob- 15 bin 2 and having a tapered closed bore 3 which considerably facilitates threading and protects the thread from sprin ing out during the winding operation.

4 denotes the thread guide frame adapted 20 to swing on the shaft 5 and carrying besides the thread guide 1 a bent bar 6 adapted to abut on the spool 2. In order to regulate the pressure under which bar 6 abuts on the spool, the following means are provided: A counterweight 8 is adjustably mounted on a threaded bolt 7 which is fixed in a block 9. The latter can be exactly adjusted on a pin 10 mounted on the lower portion of the thread guide frame 4, and fixed by this pin in the desired position. A scale 11, provided on frame 4, allows the angular position of the counterweight 11 to be read off. The pressure exerted by the bent bar 6 upon the spool can thus be exactly set and balanced, any return movement of bar 6 during increase of the spool being impeded by a locking pin 13 known per se and rockingly mounted on a shaft 12 carried by the thread guide frame 4. The locking pin 13 is held in looking position 9 by a flat spring 13 that acts upon the releasing lever 13", so that only the motion to the right of the thread guide in accordance with the increase of the spool is admitted. To release the locked state, a slight pressure exerted by hand on the lever 13 to the left will do. V

The thread guide frame 4 has projecting from it an extension 14 which carries a pin 15 having a transverse bore wherein a small bar 16 is shiftably guided. This bar 16 can swing I guide frame about a and 1s '01? HORGEN, NEAR ZURICH, SWITZERLAND d in Switzerland March 2, 1929.

pin 17 mounted on the machine frame connected by means of a screw 18 to a regulating segment 19 having an areuate slot 19 and a scale 19'.

the bar 16 are secured against axial displacement by an adjustable pin 17.

25 denotes a sector ad according tothe despool and fixed by apted to rock on-pin 26 and serving to disengage the driving coupling. As soon as sector 25 is rocked by the described releasing devi ce about pin26 in a counterclockwise direction, Figure 1, arm 25" of sector 25 releases the starting lever 25". This latter lever is under the action of the coupling operation of this well known-in th 1905 is illustrative.

The described regulating and stopping mechanism operates as follows By shifting the counterweight 8 on the threaded bolt 7 and by of the block 9 that car angular adjustment ries bolt 7 with the counterweight 8, relatively to the thread guide frame 4 a double adjustment of the bent bar 6 on the spool 2 is possible. \Vith increasing diameter of the spool 2 the thread 4 with the bar 16 and pin 21 of segment 19 are swung to the right until pin 21 brings the dete ctor wire 22 of the o i v 1,866,613
