UNITED STATES PATENT orFicE.
eo'r'rwAL'r SIEBER, or PLA'UEN, GERMAN .ivinrnon or siicunnve THE END wmnines or noiszenvsf I No Drawing. 4
To'all who'm it may concern:
Be it known that I, GorrwALr SIEBER, a citizen of the Republic of Saxony, residing at Plauen, in Saxony, Germany, have invented certain new and useful Improvements in Methods of Securing the End Vvindings of Bobbins, of which the following is-a specification.
This invention relates to method of securing the end-windings of bobbins wound on spooling machines. The bobbins placed in the shuttles of embroidering machines formerly were produced in bobbin winding machines by windinga thread on the rapidly rotating spool-bar, thereby moving the thread to and fro in the axial direction of the latter. This winding operation had to be continued till the necessary diameter and the bulged form of the bobbin was attained, and then the latter was shifted laterally as far as space was required for the formation of a new bobbin.
Thereby the securance of the end windings was of very great importance since the bobbin had to be prevented from unwinding when in use. For this purpose the endwindings were placed across the bobbin in the form of several thread-layers and the thread-end which remained between the ready and half-ready bobbin sometimes was twined or twisted with the beginning of the bobbin, or a loop was formed of any thread-layer of the bobbins crosswinding and twisted or joined with the thread-end.
All these methods are, however, very disadvantageous as the bobbins in spite of all caution unwound very easily in operation when being packed and placed in the shuttles so that a considerable loss of thread ensued. In addition thereto, it must be considered that a lot of yarn was squandered by the necessity of placing the end-thread in form of several windings around the bob bin because the yarn wound across the bobbin as is well known cannot be used r'or the embroidering operation. Now since about 1000 shuttles are simultaneously in oper ation in great embroidering machines of modern construction the loss in yarn therefore is very considerable.
In the present method all these drawbacks completely are done away with, since a feature of the present invention consists in that the end-windings of the bobbin formed of the last thread and laid across the Specification of Letters Patent.
Application filed September in, 921. Serial 110499.856;

bobbin are completely omitted. Instead thereof a number of windings are formed of a special thread and also placed across the bobbin. v
In operation the present new method is applied as follows; As soon as the bobbin is wound to the desired thickness a thread arising from a special source of thread is placed several times around or across the body of the bobbin. For this purpose the bobbin on the bobbinbar is shifted for a whole bobbin length in'longitudinal direction and thus conducted to the operation of winding by means ofa special thread.
In the specification the thread serving for the winding or spoolingjoif the bobbin-body is called'bobbin-thread while the thread destined to prevent the end-windings of the bobbin from unwinding is named bindingthread. lNhen the bobbin wound on the spool-bar of a bobbin-winding machine has attained the diameter desired the finished bobbin as stated above, by means of a suitable device is removed or shifted so far as to make room for the productlon of a new bobbin. After this the binding-thread by means of a special device, for instance a thread-layer, rotating about the threadguide, is laid several times around the bobbin, the beginning of the bobbin-thread thereby being advantageously held fast by means of a clamping device arranged outside of the bobbin diameter.
After the binding-thread is placed several times around the bobbin this thread is in troduced into the clamping device or any other device and fixed there. Thus both the beginning and the end of the binding-thread are held fast, and by means of any suitable device these two threads are twisted, and the bobbin is finished.
The advantages of the invention are vari ous. Firstly the drawback is avoided of rendering considerable quantities of yarn useless, since by means of this invention the embroidery thread may be completely used binding thread than for the bobbimespecially when the bobbin-body consists of very expensive thread. On the other hand, material of little value may be applied for the winding of the binding-thread; and the sort of yarn to be used or used for the bobbin can be marked by means of a coloured bindthe beginning of the binding-thread being ing-thread so that errors formerly arising in embroidering with thread of different thickness thus are completely excluded.
Having now fully described my invention I declare that what I claim is 5- 1. Method for securing the end-windings of bobbins in shuttle embroidering machines,
consisting in that after the completion of the bobbin-winding a binding-thread, from a special source of thread, is placed'in several windings around the bobbin-body and then the beginning and end of the binding I thread are twisted, substantially as described.
2. Method for securing the end-windings of bobbins in shuttle embroidering machines, consisting in that after the completion of the bobbin-winding a binding-thread, from cial source of thread, is placed in sevwindings around the bobbin-body and the bobbin-winding a coloured bindingthread froma special source of thread 15 placed in several windings around the bobbin-body, and the beginning ofthe bindingthread being'seized by a clamping-device before the commencement of its winding on the bobbin till it is twisted with the end of the binding-thread, substantially as scribed.
4. Method for securing the. end-windings of bobbins in shuttle embroidering machines,
consisting in that after the completion of the bobbin-winding, a binding-thread of minor materialthan the bobbin-thread from d a special source of thread is placed in several windingsaround ,the bobbinbody and the beginning of the binding-thread being seized by a clamping-device before the commencement ofi'ts winding on the bobbin,.
till it is twisted; with the end of thebindingthread, substantially 'as described.
