KARL KELLER in ARBON, Schweiz. Stoffdrückervorrichtung für Stickmaschinen. Patentiert im Deutschen Reiche vom 21. März 1911 ab.KARL KELLER in ARBON, Switzerland. Press device for embroidery machines. Patented in the German Empire on March 21, 1911.

Gegenstand der Erfindung ist eine Vorrichtung für Stickmaschinen zum Festhalten des Stoffes während des Stickens, bei welcher in jeder Etage der Stickmaschine eine mit Stoffdrückern oder Stoffhaltern ausgerüstete schwingbare Welle vorgesehen ist.The invention relates to a device for embroidery machines for holding the Fabric during embroidery, with one on each floor of the embroidery machine with pressers or fabric holders equipped swingable shaft is provided.

Gemäß der Erfindung sind die Stoffhalterwellen sämtlicher Etagen der Stickmaschine an mehreren Stellen derart zwangläufig miteinander verbunden, daß durch an jeder Verbindungsstelle angreifende Federn der Anpressungsdruck der Stoffhalter jeder Welle an der betreffenden Stelle entsprechend den Schwankungen des Gatters für sich geregelt und durch ein gemeinsames Zugorgan trotz einer etwaigen Torsion der Welle an allen Stellen zu gleicher Zeit aufgehoben werden kann.According to the invention, the fabric holder shafts are all floors of the embroidery machine so inevitably connected to each other at several points that through at each connection point attacking springs the contact pressure of the fabric holder of each shaft at the point in question according to the Fluctuations of the gate regulated independently and despite a common pulling organ a possible torsion of the shaft at all points at the same time can.

Auf der Zeichnung ist eine beispielsweise Ausführungsform des Erfindungsgegenstandes dargestellt, und zwar zeigtThe drawing shows an example of an embodiment of the subject matter of the invention shown, namely shows

Fig. ι die Vorrichtung im Aufriß,
Fig. 2 dieselbe im senkrechten Schnitt und Fig. 3 eine Einzelheit eines Teiles der Vorrichtung. Fig. Ι the device in elevation,
FIG. 2 shows the same in vertical section and FIG. 3 shows a detail of part of the device.

Mit ι und 2 sind die beiden Stoffdrückerwellen der oberen und unteren Etage einer Zweietagenstickmaschine bezeichnet, die mit Stoffdrückern 3 ausgerüstet und in Lagern 4 schwingbar gelagert sind. Die beiden Wellen 1 und 2 sind an mehreren auf die Länge derselben gleichmäßig verteilten Stellen (im gezeichneten Falle an drei Stellen) durch Lenkerstangen 5, die an auf den beiden Wellen sitzende Hebelarme 6 und 7 angreifen, zwangläufig miteinander verbünden. Für jede Stange 5 ist 40 With ι and 2, the two presser shafts of the upper and lower levels of a two-level embroidery machine are referred to, which are equipped with pressers 3 and mounted in bearings 4 to swing. The two shafts 1 and 2 are inevitably connected to each other at several points evenly distributed over the length of the same (in the case shown at three points) by means of handlebars 5 which engage lever arms 6 and 7 seated on the two shafts. For each rod 5 is 40

eine Zugfeder 8 vorgesehen, die einerends an den oberen Querträger 9 des Stickmaschinengestelles und anderends an einen Stellring 10 angreift, der verstellbar auf der Stange 5 befestigt ist. Die Federn 8 sind bestrebt, die Arme 6 und 7 nach oben zu ziehen und dadurch die Stoffhalterwellen 1 und 2 so zu drehen, daß dieselben mit den Stoff haltern 3 gegen den Stoff 11 (Fig. 2) unter Druck anliegen und denselben zwischen sich und den Stichplatten 12 festhalten.a tension spring 8 is provided, one end of which is attached to the upper cross member 9 of the embroidery machine frame and at the other end engages an adjusting ring 10 which is adjustably fastened on the rod 5 is. The springs 8 strive to pull the arms 6 and 7 upwards and thereby to turn the fabric holder shafts 1 and 2 so that they hold with the fabric 3 against the fabric 11 (Fig. 2) bear under pressure and the same between you and the Hold the throat plates 12 firmly.

Die Federn 8 ermöglichen, durch Verstellung der Ringe 10 den Anpressungsdruck der Stoffhalterwellen ι und 2 an den erwähnten Verbindungssteilen der Wellen entsprechend den Schwankungen des Gatters für sich zu regeln.The springs 8 enable the contact pressure of the fabric holder shafts by adjusting the rings 10 ι and 2 on the mentioned connecting parts of the shafts according to the To regulate fluctuations of the gate for yourself.

Die Stoffdrücker 3 werden zwangläufig vom Stoff abgehoben, und zwar geschieht dies durch folgende Vorrichtung. Auf der Antriebswelle 13 der Stickmaschine sitzt eine als Auslösorgan für die Stoffhalter dienende Hubscheibe 14, gegen deren Umfang der mit einer Rolle ausgerüstete eine Arm eines am Stickmaschinengestell gelagerten Winkelhebels 15 anliegt, dessen anderer Arm durch eine Stange 16 mit einem auf der Welle 2 befestigten Arm 17 verbunden ist. Die Stangen 5 sind noch unter sich zwangläufig verbunden, und zwar ist für jede Stange am Querträger 9 ein Winkelhebel 18 (Fig. 1) gelagert, dessen einer Arm mit seinem gabelförmigen Ende an einen festen Zapfen 19 der zugehörigen Stange 5 angreift, während dessen anderer Arm durch eine gemeinsame Zugstange 20 mit den Winkelhebeln 18 der übrigen Stangen 5 verbunden ist.The presser foot 3 are inevitably lifted from the fabric, and this happens through following device. On the drive shaft 13 of the embroidery machine sits a trigger member for the fabric holder serving lifting disc 14, against the circumference of the with a roller equipped one arm of an angle lever 15 mounted on the embroidery machine frame rests, the other arm of which is connected by a rod 16 to an arm 17 fastened on the shaft 2 is. The rods 5 are still inevitably connected to each other, namely an angle lever for each rod on the cross member 9 18 (Fig. 1) stored, one arm of which with its fork-shaped end to a fixed Pin 19 of the associated rod 5 engages, while the other arm by a common Tie rod 20 is connected to the angle levers 18 of the remaining rods 5.

Claims

the part of the cam plate 14 that is radially less distant from the shaft 13 is in contact, hold the fabric holder 3 under the action of the springs 8, the fabric (Fig. 1 and 2); as soon as but the part of the cam plate that is further away from the shaft 13 on the lever 15 acts and rotates the same, the shafts 1 and 2 become through the intermediary of the parts 16, 17, 7, 5, 6 and 18, 19, 20 rotated so that the fabric holders 3 of the two shafts 1 and 2 are lifted from the fabric at the same time, d. H. the contact pressure of the fabric holder without the torsion of shafts 1 and 2 having any effect can be, is canceled in all places at the same time.

In Fig. 3 it is shown how all of the tension springs 8, which are used to press the fabric holder 3, instead of individually, as shown in FIGS. 1 and 2, can be controlled simultaneously with one another.

For this purpose, an angle lever 21 is provided for each spring 8; at one of them Arm engages the spring, the other end of which is attached to the associated handlebar 5 is attached. All angle levers 21 are by a common pull rod 22, which is on the other arms of the angle lever engages, connected to each other. With the sticker stand a third arm 21 'is connected to the nearest bell crank 21, by means of which all angle levers 21 are rotated and thereby all springs 8 can be stretched more or less. This arm 21 'is on a solid, toothed one Segment 23 can be determined.
