Description

Vorrichtung an Nähmaschinen zur Verhinderung einer Drehung des Schnurrades im falschen Sinne. Die Erfindung betrifft eine Vorrichtung zur Verhinderung einer Drehung des Schnurrades im falschen Sinne und besteht darin, daß an der Unterseite des Näbmaschinentisches eine in die Schnurrille des Schnurrades eingreifende, im Profil der Schnurrolle angepaßte Bremsscheibe mit mehreren exzentrischen Likhern angeordnet ist, deren eines den in der Höhe verstellbaren Lagerbolzen für die Bremsscheibe aufnimmt. Hierdurch wird neben der Nachstellbarkeit der Brernsscheibe in senkrechter Richtung auch die Möglichkeit gegeben, die Scheibe nach völliger Abnutzung an einer Stelle zu verdrehen, so daß eine frische Bremsfläche zur Verfügung steht.Device on sewing machines to prevent the cord wheel from turning in the wrong sense. The invention relates to a device for preventing a Rotation of the string wheel in the wrong sense and consists in that at the bottom of the sewing machine table engaging in the string groove of the string wheel, im Brake disc adapted to the profile of the line roller with several eccentric liqueurs is arranged, one of which is the height-adjustable bearing pin for the brake disc records. As a result, in addition to the adjustability of the brake disc in a vertical position Direction also given the possibility of the disc after complete wear on one Rotate position so that a fresh braking surface is available.

Der Erfindungsgegenstand ist in der Zeichnung dargestellt. Die Bremsscheibe i. ist niit mehreren Löchern exzentrisch versehen, um bei Abnutzung das Umwechseln zu ermöglichen. Der Rand der Scheibe ist dein Radprofil entsprechend geformt und schleift während einer Drehung des Schnurrades in dessen Rille, solange dies in der gewollten Richtung bewegt wird, anderenfalls wird das Rad sofort fest gebremst. Die Bremsscheibe i ist auf dem Bolzen h. gelagert, dessen bügelförrniger Teil g durch eine Schraubklemme an dem Teil f befestigt ist. Der Teil f ist an der Unterseite des Nähmaschinentisches befestigt.The subject of the invention is shown in the drawing. The brake disc i. is provided with several eccentric holes so that it can be changed over when worn. The edge of the disc is shaped according to your wheel profile and grinds in its groove during a rotation of the cord wheel, as long as it is moved in the desired direction, otherwise the wheel is braked immediately. The brake disc i is on the bolt h. stored, the bügelförrniger part g is attached to the part f by a screw terminal. The part f is attached to the underside of the sewing machine table.
