Description
Kreuzspulenhalter aus Federdraht. Gegenstand vorliegender Erfindung ist ein Kreuzspulenhalter für Nähmaschinen aus Federdraht, der die Eigenschaft hat, sich vermöge seiner Bauart fest auf den Garnrollenstift selbsttätig festzuklemmen.Cross-coil holder made of spring wire. Subject of the present invention is a cross-bobbin holder for sewing machines made of spring wire, which has the property by virtue of its design to clamp itself firmly onto the spool pin.
Auf der Zeichnung ist der Gegenstand der Erfindung dargestellt, und zwar zeigt Abb. r eine Ansicht von der Seite, Abb. a eine Ansicht von rechts, Abb. 3 eine Ansicht von oben, während Abb. q. zeigt, wie der Kreuzspulenhalter auf den Garurollenstift aufgesetzt wird und sich selbsttätig festklemmt.In the drawing, the object of the invention is shown, and although fig.r shows a view from the side, fig.a a view from the right, fig. 3 is a view from above, while Fig. Q. shows how the package holder is attached to the Garu roller pen is placed and automatically clamps.
Der Kreuzspulenhalter besteht aus einem in der Mitte bei a umgebogenen Federdraht. Die durch die Umbiegung entstehenden Schenkel b, c sind bei d zu einer doppelten ineinanderliegenden Schraubenfeder e, f ausgebildet, wobei die 'übrigbleibenden Schenkelenden g, lt halbkreisförmig auslaufen.The cross-bobbin holder consists of a spring wire bent in the middle at a. The legs b, c resulting from the bend are formed at d to form a double nested helical spring e, f , the remaining leg ends g, lt tapering off in a semicircle.
Die Befestigungsart auf dem Garnrollenstift ist kurz folgende: Der Kreuzspulenhalter wird mit den ineinanderliegenden Schraubenfedern e, f auf den Garnrollenstift i aufgeschoben; wenn nun der Garnrollenstift auf :die Einknickungen k, l der Schenkel b, c trifft, so drückt der Stift i die ineinanderliegenden Spiralen e, f auseinander, wodurch sich die einzelnen Gänge der Spiralen fest an den Stift anpressen. Die Schenkelenden g, la legen sich über den Maschinenarm m und sichern den Kreuzspulenhalter gegen seitliche Verschiebung. Jetzt wird die Kreuzspule auf die Schenkel b, c aufgeschoben und durch die Federkraft der Schenkel festgehalten, so daß sie sich nicht drehen kann.The type of fastening on the spool pin is as follows: The cross-bobbin holder is pushed onto the thread spool pin i with the helical springs e, f lying one inside the other; If the thread spool pin hits: the kinks k, l of the legs b, c , the pin i pushes the nested spirals e, f apart, whereby the individual turns of the spirals press firmly against the pin. The leg ends g, la lie over the machine arm m and secure the package holder against lateral displacement. Now the cheese is pushed onto the legs b, c and held in place by the spring force of the legs so that it cannot rotate.
