THREAD HOLDING MEANS FOR LAYING-ON A THREAD TO A SPOOL Filed July 18, 1955 F/G. 3 V F/G. 4
INVEN TOR. ALBERT KRESSLE/N I BY Hm ATTQRNEYi United States THREAD HOLDING MEANS FOR LAYING-ON A THREAD TO A SPOOL Albert Kresslein, 'Dettingen, Germany, assignor to Vereinigte Glanzstott Fabriken A.G., Wuppertal- Elberfeld, Germany, a corporation of Germany The present invention relates to thread holding means for laying-on a thread to a flanged spool or bobbin.
-A conventional method of laying-on a thread to a flanged spool or bobbin is to wrap the thread several times about the body of the spool. This method is quite inconvenient and unreliable as it does not assure that the thread is tightly held on the spool. In practice there is nearly always a certain slippage which may result in damage to the thread and the spool body. It has been proposed to use special thread holding means particularly when fine threads are worked. These holding means comprise wedge shaped slots formed in the wall of the spool, or rings with bent-off branches which serve to grip the end of the thread. Such auxiliary thread holding means are not suitable for heavier threads which have a substantial bending stiffness. It is also desirable to shorten the overhanging end of the thread so that the same does not extend beyond the holding means. When the threads are fine, one can simply tear off the pro truding end of the thread, but for strong threads, for instance multiple cored, this is not practical.
Accordingly, one of the objects of the invention is to provide novel and improved thread holding means which safely retain the thread and permit to cut off the overhanging end of the thread.
Another object of the invention is to provide novel and improved thread holding means which firmly clamp the thread in position and include a cutting edge by means of which the protruding end of the clamped thread can be conveniently cut off.
Still another object of the invention is to provide novel and improved thread holding means which can be conveniently fitted in a recess provided for this purpose in the body of the spool, more specifically in the flanged part therof and which are held in the recess in operative position by engagement with the wall of the recess.
Other and further objects, features and advantages of the invention will be pointed out hereinafter and set forth in the appended claims forming part of the application.
In the acompanying drawing several preferred embodiments of the invention are shown by way of illustration and not by way of limitation.
In the drawing:
Fig. l is a fragmentary plan view of a flanged spool or bobbin equipped with a thread holding means according to the invention.
Fig. 2 is a plan view of the clamping member of the holding means.
Fig. 3 is a plan view of the cutting member of the holding means, and
Fig. 4 is a plan view of a modification of the cutting member.
Referring to the figures in detail, the flange 1 of a spool 01' bobbin has a transverse bore 2 which is continued in a slot 3. The wall of slot 3 is laterally expanded for instance, by mi ling on the side of the flange facing the roll of thread. The slot and more specifically its enlarged part 4 serves to accommodate the thread holding means.
atent Patented Feb. 28, 1961 The holding means comprise a-clamping spring 5 and a cutting member 6. The clamping spring which can best be seen in Fig. 2, is of generally V-sha'ped configuration when in its relaxed condition. The ends of the spring are bent back to form two. jaws 7. The cutting member is of generally U-shaped configuration and is made of springy material. The branches of the cutting member are biased so that they are slightly spread apart when then cutting member is relaxed. The cutting edge is formed at the end of a tongue extending from the bight of the member. It is shown in Fig. 3 as an edge 8 forming a right angle with the longitudinal axis of theimembe'r and in Fig. 4 as a cutting edge 8' forming an acute angle with the longitudinal axis of the member.
The holding means are assembled by fitting first the cutting member and then the clamping spring in the enlargement 4 of slot 3. Due to the springiness and the configuration of the clamping spring and the cutting member both these components are safely retained within the slot without special mounting-or anchoring means. As is apparent, jaws 7 are forced toward each other into a substantially parallel position to clamp a thread therebetween.
A thread to the laid-on is threaded from the interior of the spool through the bore 2, 'then gripped from the outside and pulled into slot 3. As a result, cutting edge 8 or 8 cuts off the overhanging end of the thread whereas the thread to be spooled is held between the jaws 7 of spring 6 by reason of the spring lying on the side of the flange facing the roll of thread.
. While the invention has been described in detail with respect to certain now preferred examples and embodiments of the invention it will be understood by those skilled in the art after understanding the invention, that various changes and modifications may be made without departing from the spirit and scope of the invention, and it is intended, therefore, to cover all such changes and modifications in the appended claims.

2. A thread holding assembly according to claim 1, wherein said cutting edge forms a substantial right angle with the clamping jaws in the substantially parallel position thereof.
3. A thread holding assembly according to claim 1,
wherein said cutting edge forms a substantial acute angle with the clamping jaws in the substantially parallel position thereof.
4. A combined thread holder and cutter for mounting within an indent of a spool comprising, in combination, a cutting member, a spring having a pair of pre-stressed clamping jaws yieldably converging toward said cutting member, said cutting member having a cutting edge alongside said pair of jaws lying in a plane spaced apart from the clamping surfaces of said jaws, said jaws releasably gripping a thread therebetween with the end-of the thread adjacent to the cutting edge of said member, said spring including a pair of branches intersecting with each other to define a spring of substantially V-shaped configuration, the ends of said branches being inwardly bent back to form said gripping jaws, and the outside of said branches having portions in substantially parallel relationship.
5.
