JEAN SCHWEITEB, OF HORGEN, NEAR ZURICH, SWITZERLAND.

CROSS-ENDING MACHINE.

To all whom it may concern:

Be it known that I, JEAN SOHWEITER, of Horgen, near Zurich, Switzerland, a citizen of the Swiss Confederation, and resident of Horgen, near Zurich, Switzerland, have invented certain new and useful Improvements in Cross-finding Machines, of which the following is a specification.

The present invention relates to improvements in cross-winding machines and consists principally in the employment of an intermediate roller actuated by a driver which also elfects the rotation of the winding spool and the reciprocation of the thread carrier as well as the automatic throwing out of the winding spool follows either after tearing or breaking of the thread.

The drawing illustrates one way of constructing such a cross winding machine, and in the views shown: Figure 1 is a side view partly in section; Fig. 2 is a top plan view; Figs. 3 and t show two different operating positions; Figs. 5 and 6 represent two views of a modified construction of the feeder arms; and Figs. 7, 8 and 9 show three views of the thread carrier on an enlarged scale.

Referring to the drawings in further detail, a is the driving shaft on which the driving disk I) is mounted. On the stand 0 there is mounted a frame d on which the intermediate roller 6 'is journaled in bearings adapted to have slight vertical movement. This intermediate roller lies normally with one end on the driver Z). The opposite end of the intermediate roller carries a toothed wheel 9 which meshes with a second toothed wheel 72, carried on a shaft 2'. This shaft 2' is journaled in hangers 7a in the frame work (Z. The winding spool 0 rests in a swinging frame 79, mounted on bolts 1 in the frame work (l.

s is the thread carrier composed of spring plates, one end of which always lies against the spool. It is placed on a carrier t which has underneath, a pin n that engages within a groove in the grooved disk m on the shaft 71. The carrier t can slide on the guide rails 10. In order to facilitate the replacing of the spool in the machine, the thread carrier may be set in the position indicated by dotted lines in Fig. 1. The spool 0 can in the usual manner run loose in the frame 79 and is, from the pressure of a weight 4), on said frame given a constant pressure on the intermediate roller 6. The journal of the roller 6, mounted in the frame d is touched under- Specification of Letters Patent.

neat-h by a double-armed lever 00 swinging on a bearing w. One end of this lever is loaded by a weight 00, whereas the other end of the lever-arm has a stop g and is bent over at the top. Against the stop lies a projecting piece 2 aflixed to the shaft 2. The shaft z turns in the frame d and carries an arm 7 which is provided with a resilient threadguide f, and m is a stop for the threadguide.

At normal tension on the thread, the arm 7 takes the position indicated in Fig. l, i, 0. it stands vertical. The projecting'piece a rests on the bent part 3/ of the lever :11. The shaft 2 carries further, an adjusting ring 2 in which one end of a spring a is fastened; the free end of which spring rests on a bar a. A finger Z), which grips below the spring, is also attached to theshaft a.

On one side of the frame 79 is journaled a roller 0, which engages within an upwardly inclined notch g of a lever d, said lever oscillating in the frame cl. A spring 6 constantly tensions the lever against the roller 0. This arrangement has for its function to automatically disengage the winding spool as will be presently explained.

The machine operates as follows. As already remarked, the intermediate roller 6 is driven by the rotation of the driver Z) which also, by means of the gears g, 72 rotates the grooved disk m. Through this, the carrier 6 and with it the thread guiding arm are also set in motion, back and forth.

With the increase of the diameter of the winding-on-spool, the frame p raises itself upor describes an are around the bolts r. In the same way the thread-carrier is also lifted and describes an are around its axis and since these two axes coincide, it follows that as the thread spool increases (within the possible limits of the diameter of the latter) the point where the thread leaves the carrier always lies upon the spool so that notwithstanding the increasing diameter of the spool, sharp spool edges will be assured. When thespool has reached the regulation size so, in the meantime, has the roller 0 arrived adjacent the inclined recess 9. There, the spring 6 draws the lever d in the direction of the arrow, causing the roller 0 to rise slightly and carry with it the frame 79 and consequently the spool is held in suspended position and cannot any longer be driven by the intermediate roller.

As is usual, the arm 7 will, at normal left-hand edge of the projecting piece a will.

depress the right end of the lever w and raise the left end thereof. This will cause the intermediate roller 6 to be lifted from the driver I). This position is shown in Fig. 3, Through this means the connection between driver and intermediate roller is broken.

Should the thread-tension now cease altogether, then will the spring 12. expand and gradually erect the arm.' When the latter has regained its upright position, the arm 6 meets with the free end of the spring n wherebythe further influence of the spring on the arm f is stopped. The latter has by nlow regained its working position and the wound-up thread will balance it during the operation. Should, however, breaking of the thread occur when the arm is in the position shown in Fig. 3, the arm f will be swung to the right by the spring 41. square set edge of the projecting piece a acts on the lever 00 and produces the same effect as in the tearing of the thread. The position of the separate parts when the thread'breaks is indicated in Fig. 4.

Another way of arranging the arm is represented in Figs.'5 and 6, where the threadguide can be thrown out to the side. i As will be seen in Fig. 6, the thread guide f is made U-shaped and is swivelly mounted on the arin f. A spring f fixed to the guide f and the arm f has the function always to retain the thread-guide in the'position shown in Fig. 6. When it is desired to take hold of the thread, it will be necessary only to bring the thread-guide into the dotted position of Fig; 6 by means of the handle f and it will snap back into its working position as soon as released.

In the described arrangement, the armf is suitably placed so that it can by its own Weight hold the thread in tension, that is it tends to draw out the thread between the rods d and 03 In thread breaking, the operation is the same as in the already described A instance in Fig. 1.

As regards the thread-carrier, it should be stated, that the eye 7L2 (Figs. 7 to 9) at the workingpoint is inclosed by a wire h in order to prevent any jumping ofi or out of the thread during the winding. This wire may suitably be of brass. V
