Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die vorliegende Vorrichtung dient zur sicheren Zuführung des Nadelfadens für nach Art einer Zange ausgebildete Nähmaschinen, wie solche z. B. in Fig. 1 dargestellt sind. In einer cylindrischen Hülse A (Fig. 1 und 2) ist der Boden E drehbar angebracht. Er besteht zu diesem Zwecke aus zwei Platten E und E1, von denen die letztere zwei Aussparungen a hat, durch welche vorstehende Plättchen a1 des Cylindermantels A hinter Platte E1 treten und so den Boden festhalten. Durch Boden E E1 ist ein Spulenhalter C gesteckt, auf dessen Ende ein Zahnrad B befestigt ist, welches wiederum durch Bügel M gehalten wird. Auf dem Halter C dreht sich die Spule D, welche von einer in der Spannung durch G regulirbaren Feder beeinflufst werden kann. Schraube G dreht sich im festen Boden R, an dem die Feder F an einem Ende ebenfalls befestigt ist.The present device is used for the safe feeding of the needle thread for sewing machines designed in the manner of pliers, such as such. B. are shown in FIG. In a cylindrical sleeve A (Fig. 1 and 2), the bottom E is rotatably mounted. For this purpose, it consists of two plates E and E 1 , of which the latter has two recesses a through which protruding plates a 1 of the cylinder jacket A pass behind plate E 1 and thus hold the floor in place. A bobbin holder C is inserted through the bottom EE 1 , on the end of which a gear wheel B is attached, which in turn is held by a bracket M. The coil D rotates on the holder C , which can be influenced by a spring whose tension can be regulated by G. Screw G rotates in the solid ground R, to which the spring F is also attached at one end.

Boden E kann auch lose drehbar in den Cylinder A eingesetzt werden, so dafs das Ganze in diesem Falle durch Bügel M gehalten und am Herausfallen verhindert wird.Bottom E can also be inserted loosely rotatable into cylinder A , so that in this case the whole thing is held by bracket M and prevented from falling out.

Durch die von Feder K beeinflufste Zahnstange / wird bei Bewegung der Zangenschenkel Zahnrad B (und eventuell Boden E bei losem Boden) mit Halter C und Spule D nach links und rechts herumgedreht und hierdurch der Faden L bei der Rechtsdrehung der Spule freigegeben, bei der Linksdrehung angezogen, dabei kommt dann die Spannvorrichtung, bestehend aus Feder H und Spannschraube G, bei der Bildung des Stiches zur Wirkung.The rack /, which is influenced by spring K , turns the tong legs, gear wheel B (and possibly base E with loose base) with holder C and bobbin D to the left and right, and this releases the thread L when the bobbin is turned to the right and when the bobbin is turned to the left tightened, the tensioning device, consisting of spring H and tensioning screw G, comes into effect when the stitch is formed.

Claims (1)

Patent-Anspruch:Patent claim: Eine Vorrichtung zur gesicherten Zuführung des Nadelfadens für nach Art einer Zange ausgebildete Hand - Nähmaschinen, dadurch gekennzeichnet, dafs die Fadenspule (D), auf dem Boden (E) eines cylindrischen Gehäuses (A) sitzend, mit ihrem Träger durch ein Zahnstangengetriebe (IB), von dem einen Zangenschenkel aus beim Arbeiten der Maschine in Vor- und Rückwärtsdrehung versetzt wird, also den Nadelfaden freigiebt und wieder aufnimmt, während eine auf die Fadenspule wirkende Bremsfeder (F G) dem Faden beim Anziehen des Stiches die erforderliche Spannung ertheilt.A device for the secure feeding of the needle thread for hand sewing machines designed in the manner of pliers, characterized in that the thread spool (D), sitting on the base (E) of a cylindrical housing (A) , is supported with its carrier by a rack and pinion gear (IB) , from which a pair of pliers is set in forward and backward rotation when the machine is working, i.e. releases the needle thread and takes it up again, while a brake spring (FG) acting on the thread bobbin gives the thread the necessary tension when the stitch is pulled.
