' Application filed August 1, 1910; Serial No. 574,795.

To all whom it may concern:

Be it known that I, JEAN Sonwnrrnn, a citizen of the Swiss Confederation, and resident of I-Iorgen, near Zurich, Switzerland, have invented certain new anduseful Improvements in Cross-Winding Machines; and I do hereby declare that the following is such a full, clear, and exact description of the same as will enable others skilled in the art to which it pertains to make and use the same.

The invention relates to cotton spooling machines, more particularly to the construction of the thread guide and the construction of the mechanism by which motion is imparted thereto and the construction, operation and arrangement of the parts hereinafter described and claimed.

In the accompanying drawings, forming part of this specification, Figure 1' is a side elevation of my cross winding device. Fig. 2 is a top plan view of the same, Fig. 3 is a detail view of the thread guide, Fig. 4 isa side view and Fig. 5, a top plan view of one modification thereof, Figs. 6 and 7, similar views of another modification.

Similar reference characters refer to similar parts in all the drawings.

Referring more particularly to the Figs. 1 to 3' a is the driving shaft on which is seated the driving disk 6. On the stand 0 d in which is journaled the intermediate roller e revoluble therein. This'intermediate roller rests with one part constantly on the driving disk 6. The end of the intermediate roller shaft 6 oppositely disposed to the driving disk 6 carries a toothed wheel 9 in mesh with'another gear wheel 7L seated on a shaft 2'. The shaft 2' is journaled in hangers is of the'frame 03. The bobbin 0 rests in a box ;0 which can pivot on the trunnions r in the frame d. The thread carrier 8 is composed of resilient metallic strips and rests constantly against the bobbin. 7 Said carrier is arranged on-a carriage t and carries at its under side the usual pin which enters into the groove m of a disk m seated on the shaft 2'. The carriage t is slidably disposed on the guide rails u. The bobbin 0 is adapted to rotate loosely, in the well known manner in the box 72 pressing constantly against the intermediate roller 6. A double-armed lever 00 pivoted at W frictionally engages'the shaft 6 of the intermediate roller 6. That ortion of the lever in contact with the extremity of the intermediate shaft is loaded by a weight 03 and the oppositely disposed arm of'said lever is bent upwardly at right angles at g and this bent portion is formed with a fiat projection g The hand lever f normally resting against a stop on the are 2 isfi'rmly attached to the shaft 2 oscillating in the frame (1, and said shaft 2 carries the stop piece 2 which engagesthe flat projection 3 of the lever X. The thread guide f is fixed upon a box a on the shaft 2 about which it can freely oscillate. The de fiection of the thread guide is, ited in both directions by theflat bar s A stop finger b reaching across the thread guide, is secured to shaft 2. When laying the thread over the guide as indicated in Fig. 1, the guide is moved over to the left (in the figure) as far as the out y in the bar 2 will allow. In the event of the thread now f swings in the direction of the arrow I, Fig. 3, coming in contact with the stop finger biwhich in the same direction. Assisted by gravity, the lever f then falls still farther over to the right, turning shafts and causing the stop piece 2 topress down the upwardly extending end y of the lever at. This will cause the intermediate roller 6 to be lifted from the driver 7), thereby bringing the winding mechanism to a stop. The disengaged position of the thread guide and the hand lecut y in the f has not left the cut 3 and may therefore be turned to the left for laying in the thread, without starting the machine. Not until the lever f is by hand brought back to the position in Fig. 1, is the winding machine restarted.

In the modification 5, the thread guide f wire whose forward by a lever Z0 which frame. This lever k guide f are fixed on a box 2 rotatable on shaft ain the same manner as in the former construction shown in Figs. 1 to 3. This modification of the I device is mainly inshownin Figs. 4 and consists of thin steel movement is limited strikes against the from a skein or horizontal coils since the material is here taken off with varying tension.

In the modification shown in Figs. 6 and 7 the thread guide f independent of each other so that they can he gives an impetus to the lever f ver is shown in Fig. 3. The thread guideand the hand lever f are p however, limbreaking, the guide together with the H tended for winding the thin material either thrown out of gear separately. Tocthis end the thread guide f is secured to a bar f fixed loosely on the shaft 2 by means of a box On this box is fitted a stop piece 2 which acts on the fiat projection y of the lever 90 in a similar manner as the stop piece 2 depresses the projection in Fig. 1. Furthermore a stop finger b fixed to the box, is influenced by the bar f and a spring a is wound around the box and fixed thereto. The free end of the fixed spring 1? rests against the bar a. On the other hand a stop finger b the hand lever f and the stop piece 2 are securely fixed to the shaft 2 of the hand lever. If the thread has been inserted into the thread guide and the winding process begins, the thread guide and the hand lever have the position shown in Fig. 6. If now, the thread should be unduly drawn or pulled, the thread guide will be drawn, against the action of the spring a in the direction of the arrow 1, thereby actuating the stop piece 2 and causing the winding apparatus to be stopped. The operator is then in a position to remove all irregularities. If the pulling of the threads by the machine should gradually cease, the regulating spring a has the tendency to again press the thread guide into its working position, so that the winding process can be continued. This offers the advantage that, in case of entanglements of the skein the winding process will be interrupted and with the gradual loosening of the entanglement, the winding process again continues as described above. On the other hand if the thread should happen to break, the thread guide will be thrown backward under the action of the spring a in the direction of the arrow 11 striking against the stop finger b and causing the hand lever to be swung in the same direction. This actuates the stop piece 2 which stops the winding apparatus. hen the thread guide has swung a certain amount, bringing the stop finger b with it said finger will raise the spring n off the bar a thus preventing the spring from exerting any more pressure on the thread guide. If the winding apparatus is to be set again in working order it is merely necessary to lift the hand lever until it is at rest with the square face of the stop a on the projection y.

The essential improvement resulting from the three methods of stopping, above'set forth, comprises a method by which the thread can be inserted without setting the apparatus in operation, which is of great advantage as compared with the direct con nection of the thread guide wire with the stop lever, so far as pertains to the intermediate roller 6, which under former methods had to be stopped by hand.

In the U. S. Patent No. 1,008,301 for improvements in cross winding machines, the

intermediate roller stands under the influence of an oscillating double-armed disengaging lever, actuated by a nipper-lever under the action of a spring, in such a manner that, if the thread is violently pulled or should break, the intermediate roller will be raised simultaneously with the bobbin, so that the latter is stopped. In consequence thereof both movements of the nipper-lever result in the stopping of the intermediate roller and the bobbin respectively. In the present arrangement the be inserted and the apparatus quickly set in operation by means of a starting lever.
