Description

ι. Schrägkurbelantrieb für Bogenschiffchen-Nähmaschinen, gekennzeichnet durch eine an dem oberen, die Armwelle (a) umgreifenden Ende der Schaukelwelle (b) vorgesehene Aussparung (c) der einen Wange (d), um die Schaukelwelle (b) aus dem Arm der Maschine herausnehmen zu können, ohne die Armwelle (a) zu beseitigen. ι. Angled crank drive for bow shuttle sewing machines, characterized by a recess (c) of one cheek (d) provided on the upper end of the swing shaft (b ) that encompasses the arm shaft (a) in order to remove the swing shaft (b) from the arm of the machine without removing the arm shaft (a) .

2. Schrägkurbelantrieb nach Anspruch 1, gekennzeichnet durch die Anordnung eines Steges (f), der bewirkt, daß die beiden Wangen (d und dj der Schaukelwelle (b) beim Zusammenziehen mittels einer Spannschraube (e) sich parallel zueinander bewegen. 2. Angled crank drive according to claim 1, characterized by the arrangement of a web (f) which causes the two cheeks (d and dj of the rocking shaft (b) to move parallel to each other when they are pulled together by means of a clamping screw (e).

Hierzu 1 Blatt Zeichnungen.1 sheet of drawings.

Patent-Ansprüche:Patent Claims: Infolge der Abnutzung der beiden Wangen d und d1 der Schaukelwelle b durch die Armwelle α ist es notwendig, dieselben von Zeit zu Zeit mittels einer Spannschraube β etwas zusammenzuziehen. Die oben erwähnte Aussparung c hätte nun ein ungleichmäßiges Anspannen der beiden Wangen d und dt zur Folge. Dies wird aber vermieden durch Steg f, der so angeordnet ist, daß die Wangen d und Ii1 beim Anspannen sich parallel zueinander bewegen und dadurch auf die ganze Hublänge der gekröpften Armwelle α mit derselben in Berührung bleiben.As a result of the wear of the two cheeks d and d 1 of the rocking shaft b by the arm shaft α , it is necessary to pull them together somewhat from time to time by means of a tensioning screw β. The above-mentioned recess c would now result in an uneven tensioning of the two cheeks d and d t . However, this is avoided by web f, which is arranged in such a way that the cheeks d and Ii 1 move parallel to one another when tightened and thus remain in contact with the cranked arm shaft α over the entire stroke length of the same.
