Die in dem horizontalen Theil A 2 des Nähmäschinenarmes gelagerte Antriebswelle B trägt ein Excenter oder Herz α, welches von den flachen Backen b der gegabelten Lenkstange C umfafst wird, deren unteres Ende in c mitp einem Arm d, Fig. 2, der oscillirenden, den Stoffschieber bewegenden Welle D verbunden ist, welche unter der Platte A in den Körnerspitzen d1 d1 lagert. An dem entgegengesetzten Ende trägt diese Welle D zwei Arme d2 i3, Fig. i, mit welchen der an dem Stoffschieber/ befestigte Lenker E beweglich verbunden ist. Die Lenkstange C trägt direct unter dem Gabelende einen Zapfen oder eine Rolle c1, welche in der Nuth g einer Coulisse G, Fig. 3,4 und 5, geführt ist. Letztere ist vermittelst des Zapfens g\ Fig. 3, an dem aufrechten Theil A1 des Nähmaschinenarmes aufgehängt und mit ihrem Arm g2 in gs mit der Regulirschraube h, deren Mutter im Theil A1 des Maschinenarmes drehbar ist, gelenkartig verbunden. Diese Mutter bildet einen von aufsen in den Maschinenarm geschraubten Schraubpflock h \ dessen Gewinde eine von derjenigen der Schraube h verschiedene und entgegengesetzte Steigung hat, so dafs die letztere beim Drehen des Schraubpflockes nur um die Differenz zwischen den beiden Gewindegängen verschoben und hierdurch ein sehr genaues Einstellen der Coulisse G möglich wird. The drive shaft B , which is mounted in the horizontal part A 2 of the sewing machine arm, carries an eccentric or heart α, which is encompassed by the flat jaws b of the forked handlebar C , the lower end of which in c with p an arm d, Fig. 2, the oscillating, the shaft D moving the feed valve is connected, which is stored under the plate A in the grain tips d 1 d 1. At the opposite end of this shaft carries two arms D d 2 i 3, Fig. I, with which the slider to the fabric / fixed handlebar E movably connected. The handlebar C carries a pin or a roller c 1 directly under the fork end, which is guided in the groove g of a coulisse G, FIGS. 3, 4 and 5. The latter is suspended from the upright part A 1 of the sewing machine arm by means of the pin g 1, and is articulated with its arm g 2 in g s to the regulating screw h, the nut of which is rotatable in part A 1 of the machine arm. This nut forms a screw peg h, which is screwed into the machine arm from the outside, the thread of which has a different and opposite pitch from that of the screw h , so that the latter is only shifted by the difference between the two threads when the screw peg is turned and thus a very precise setting the Coulisse G becomes possible.
Da die Lenkstange C durch das Excenter a bewegt wird, so mufs der Zapfen c1 in der Nuth g der Coulisse G hin- und hergleiten, so dafs durch eine Veränderung der Neigung der letzteren mit Hülfe des Schraubpflockes h\ die Auf- und Niederbewegung der Lenkstange C, sowie die Schwingung der Welle D und folglich die des Stoffschiebers f mehr oder minder begrenzt werden.Since the handlebar C is moved by the eccentric member a, so must, of the pins c 1 in the Nuth g of Coulisse G slide to and fro; so that the latter h by changing the inclination by the aid of Schraubpflockes \ the up and down movement of the Steering rod C, as well as the oscillation of the shaft D and consequently that of the material slide f are more or less limited.
