CHEMICAL ENGINEERING CORPORATION, OF BRIDGEPORT, CONNECTICUT, .A. COR- PORATION OF CONNECTICUT SPINNINQ MACHINE Application filed March 29, 1928. Serial No. 265,566.

This invention relates to spinning machines, particularly of the type used in spinning threads of artificial silk or the like. Processes employing machines of this character are continuous, that is to say: the thread of artificial silk is fed continuously to the spinning device of the machine. It has been the custom heretofore, when the spinning device is full, to break the thread, to remove the filled spinning device, to substitute an empty spinning device in place of the filled one and to place the end of the thread in operative relation to the new spinning device. These operations, necessarily, consume some time during which the source is continuously feeding the thread and, in consequence, consid-' erable thread is wasted.

. The main object and feature of this invention is to provide a construction of machine which will obviate these difiiculties and save as much thread as possible.

In the accompanying drawing, which is a more or less diagrammatic front elevation of a spinning machine, the invention is embodied in a preferred and concrete form.

As there'shown, 1, 2, 3, 4, 5 and 6 indicate a plurality of spinning devices, here of the potspin type. 7, 8, 9, 10 and 11 indicate sources of supply of thread intermediate the spinning device. Obviously the number of spinning devices and sources of supply may vary; Considering now, for the moment, spinning devices 1 and 2 and source of supply 7, it will be seen that 12 and 13 indicate two godets which rotate in opposite directions, as indicated by the arrows, and which, as here shown, are located intermediate the two spinning devices. It will now be understood that if thread T is feeding to spinning device 2 it will pass over godet 13, and that when spinning device 2 is full the thread can be broken, passed over godet 12 and brought into operative relation with spinning device 1, and that this may be done without any loss, or substantial loss, of material. After the transfer of the thread has been accomplished, spin-pot 2. can then be removed and another one substituted while the spinning operation continues. It will therefore be seen that one godet directs the thread to one and the other to the other spinning device at will, and, further, that the thread can be supplied to either godet at will.

Taking now a view of a more comprehensive construction than that just contemplated it will be seen that godets l2 and 13 constitute the members of a pair,.and that there are a numberof s'uch pairs A, B, C, D and E. It will further be seen that there is a pair of godets between each two spinning devices, that members 12 and 13 of each pair rotate in opposite directions, that adjacent members 13 and 12 of adjacent pairs (as A and B) also rotate in opposite directions, that one member of each pair directs thread to one spinning device and the other to another spinning device, and that adjacent members as 13 and 12 of adjacent pairs (as A and. B) can direct thread to the same spinning device (as 2). Again, that there is a plurality of sourcesof supply of'thread, each (as 7) to supply thread intermediate the members of a pair of godets 12 and 13 where it may be directed to either member of a pair. By the foregoing means a spinning device may be supplied with thread from either of two sources at will, and a source of supply may supply thread to either of two spinning devices at will.

It will be seen that the number of spinning devices exceeds the number of sources of supply by one and that there is a source of supply intermediate each two adjacent spinning devices. Let us now assume, as indicated in full lines in the drawing, that source 7 feeds 2, source 8 feeds 3, source 9 feeds 4, source 10 feeds 5 and source 11 feeds 6. Spin-pot 1 is therefore idle. It is now desired to remove the rapidly filling spin-pots and to substitute empties. The thread from source 7 is diverted from spin-pot 2 and directed to spinpot 1. The operator then removes 2 and substitutes an empty, after which the thread is diverted from 3 and directed to 2. This transferring process continues, as indicated in dotted lines in the drawings, until the threads from the whole series of sources have been changed, and the spin-pot 6'becomes idle. It will be obvious that when the next change occurs, a process the reverse of the one just described will take place.

thread to one and the other to direct thread to the other potspin device, and a source of supply of thread to supply thread to either godet at will.
