Zusatz zum Patente J\li 87081 vom 23. April 1895.Addendum to patent J \ li 87081 of April 23, 1895.

Patentirt im Deutschen Reiche vom 20. August 1896 ab. Längste Dauer: 22. April 1910.Patented in the German Empire on August 20, 1896. Longest duration: April 22, 1910.

Durch das Patent Nr. 87081 ist ein Verfahren zum Verriegeln von Knopflöchern mittelst Maschine geschützt, bei welchem die letzten Nähstiche durch senkrecht oder nahezu senkrecht zu ihnen laufende Riegelstiche übernäht werden. Dieses Verfahren soll durch das in Vorliegendem beschriebene Verfahren vervollkommnet werden, indem der fertiggestellte Riegel feiner sowohl in seiner Gestalt, als auch in seinem Aussehen aus der Maschine hervorgeht. In der Praxis hat sich nämlich ergeben, dafs das durch Patent Nr. 87081 geschützte Verfahren einen Riegel herstellt, welcher zwar dem Befestigen durch den Handriegel nicht nachsteht, welcher aber ungleichmäfsig in seiner Bildung ist, indem das Uebernähen der Knöpflochnähstiche an den Ecken des Knopfloches Unebenheiten hervorruft. Dieser Nachtheil soll durch die Vervollkommnung des patentirten Verfahrens beseitigt werden.By patent no. 87081 a method for locking buttonholes is by means of means Machine protected, in which the last sewing stitches by vertical or almost vertical running bartack stitches are sewn over to them. This procedure is intended to be implemented by the in The presently described method can be perfected by the completed Riegel emerges from the machine more finely both in its shape and in its appearance. In practice it has been found that what is protected by patent no Method produces a bolt that does not require fastening by the hand bolt inferior, which, however, is uneven in its formation, in that the sewing over of the buttonhole sewing stitches creates bumps at the corners of the buttonhole. This disadvantage is said to result from the perfection of the patented Procedure to be eliminated.

Bei diesem neuen Verfahren wird die Uebernähung der letzten von dem Benähen der Knopflöcher herrührenden Fäden vermieden und die Nadel tritt nach dem letzten Nähstich aus dem Bereiche der Nähfäden. Die Stoffklemme macht ihre Bewegungen parallel zum Knopfloch, ohne dafs sie über die Nähstiche der Knopflochkante zurücktritt. Es werden auf diese Weise mehrere Fäden parallel neben einander gelegt und bilden eine Sicherung, ohne dafs eine Unebenheit an irgend einem Theile des Knopfloches wahrzunehmen wäre, wie dies beim Uebernähen der Nähfäden eintreten mufs. Es wird also ein tadelloser Riegel ohne störende Unebenheiten hergestellt.With this new method, the sewing of the last of the sewing of the Thread from buttonholes is avoided and the needle emerges after the last sewing stitch from the area of the sewing threads. The cloth clamp makes its movements parallel to the Buttonhole without stepping back over the sewing stitches of the buttonhole edge. It will in this way several threads are placed parallel next to each other and form a fuse, without any unevenness being perceptible in any part of the buttonhole, how this must occur when sewing over the sewing threads. So it will be an impeccable bar produced without annoying bumps.
