H. W. LIND in HAMBURG. Stichstellung an Grover & Baker'schen Schiffchen-Nähmaschinen.H. W. LIND in HAMBURG. Stitch positioning on Grover & Baker's shuttle sewing machines.

Patentirt im Deutschen Reiche vom 5· September 1877 ab.Patented in the German Empire on September 5, 1877.

Bei den bisherigen Grover & Baker-Schiffchensystemen ist die Transportirung der Art, dafs der Rücker seine Bewegung nur bei der gröfsten Stichlänge unmittelbar hinter dem Stichloch anfängt. Der vom Erfinder construirte Stichsteller-Mechanismus — zunächst für oben genanntes System bestimmt — bewirkt diese Transportirungsweise für jede Stichlänge, deren Veränderung überdies oberhalb der Maschine geschieht.In the previous Grover & Baker boat systems, the transport is of the kind that the indexer only begins its movement at the largest stitch length immediately behind the stitch hole. The stitch regulator mechanism constructed by the inventor - initially for the above System determined - causes this mode of transport to change for each stitch length moreover happens above the machine.

An der Rückerschiene S ist der verzahnte Rücker d angeschraubt, der die Transportirung des Zeuges bewirkt. Die Schiene wird vermittelst der Schraube α an dem Schiffchenbahnkörper K — der in der Vorderansicht nicht gezeichnet — befestigt. An derselben sitzt, um die Schraube b drehbar, ein zweiarmiger Hebelt, welcher sich mit dem herunterhängenden Schenkel an den Excenter E anlegt, von welchem nur der gröfste und kleinste Kreis in der Vorderansicht gezeichnet ist. Der horizontale Schenkel ist vorn gegabelt. In die Gabel greift ein auf der Stichstellerwelle w sitzender und mit einem Zapfen versehener Hebel B ein, der durch die Schraube D, welche auf einen am andern Ende der Welle sitzenden Hebel C wirkt, bewegt wird. Die Feder / soll den Hebel B herunterdrücken und so den Hebel C beständig gegen die Schraube D pressen. Das Gewinde der letzteren hat eine derartig abjustirte Länge, dafs, wenn man sie ganz niederschraubt, der horizontale Schenkel des Hebels A die Fundamentplatte der Nähmaschine nicht berühren kann. Damit andererseits der Schenkel beim Herausschrauben von D nicht auf dem Excenter E hängen bleiben kann, hat der Hebel C einen Stift s von genau abgepafster Länge, mit welchem er unter das Fundament stöfst. Die gewünschten Stichlängen bewirkt man durch Drehung der Schraube D. Zur Vermeidung unnöthigen Geräusches ist der abwärts hängende Schenkel von A an der gegen den Excenter liegenden Seite mit Leder bekleidet. Die Feder F zieht den ganzen Rücker beständig gegen den Excenter E. Der Hub des Rückers wird nach rechts begrenzt durch in die Rückerschiene eingelegtes Leder /.The toothed indexer d is screwed to the indexer rail S , which effects the transport of the equipment. The rail is attached to the shuttle track body K - which is not shown in the front view - by means of the screw α. A two-armed lever sits on the same, rotatable about the screw b , which rests with the hanging leg on the eccentric E , of which only the largest and smallest circle is drawn in the front view. The horizontal leg is forked in front. A lever B , which is seated on the stitch regulator shaft w and provided with a pin, engages in the fork and is moved by the screw D, which acts on a lever C located at the other end of the shaft. The spring / is intended to press down the lever B and thus press the lever C constantly against the screw D. The thread of the latter has such an adjusted length that, if it is screwed down completely, the horizontal leg of the lever A cannot touch the foundation plate of the sewing machine. On the other hand, so that the leg cannot get stuck on the eccentric E when D is unscrewed, the lever C has a pin s of precisely measured length with which it pushes under the foundation. The desired stitch lengths are achieved by turning screw D. To avoid unnecessary noise, the downward hanging leg of A is covered with leather on the side against the eccentric. The spring F pulls the entire indexer consistently against the eccentric E. The stroke of the indexer is limited to the right by leather inserted into the back rail /.
