KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bisher diente gewöhnlich ein vor das Sperrrad auf dem Aufziehvierkant der Federhauswelle greifender Arm, welcher an der Platine des Uhrwerkes mittels Schrauben befestigt war, zum Festhalten des Sperrades auf dem Vierkant.Up to now, one was usually used in front of the ratchet wheel on the square drive shaft of the barrel shaft Gripping arm, which is attached to the plate of the clockwork by means of screws was to hold the ratchet wheel on the square.
Eine bedeutend einfachere, in Herstellung und Anordnung billigere Vorrichtung zum Festhalten des Sperrades auf dem Aufziehvierkant der Federhauswelle ist Gegenstand vorliegender Erfindung. Dieselbe ist in der Zeichnung in Fig. ι im Längsschnitt, in Fig. 2 in der Vorderansicht dargestellt.A significantly simpler, cheaper to manufacture and arrange device for The object is to hold the ratchet wheel firmly on the square of the barrel shaft of the present invention. The same is shown in the drawing in FIG. 1 in longitudinal section, in FIG. 2 shown in the front view.
In dem Aufziehvierkante α der Federhauswelle b befindet sich vor dem Sperrade d eine Ringnut c. Eine Scheibe e aus federndem Stahlblech besitzt in der Mitte ein dem Querschnitte des Vierkantes α entsprechendes Loch und am Rande mehrere, beispielsweise drei gegen das Sperrad d zu gebogene Lappen oder Fortsätze f. Diese drücken gegen das Sperrad d, sobald die Scheibe e entgegen ihrer Federung bis zur Ringnut c gedrängt und in dieser um etwa 45 ° herumgedreht wird. In dieser Lage kann ein Verschieben der Scheibe e durch die Federung nicht mehr erfolgen, und das Sperrad d ist somit gegen axiale Verschiebung gesichert. Damit die Scheibe e sich nicht unbeabsichtigt verdrehen kann, besitzt das Sperrad in der Vorderseite eine Vertiefung g, in welche einer der Lappen oder Fortsätze f mit seinem Ende eintritt.In the pull-up square α of the barrel shaft b there is an annular groove c in front of the ratchet door d. A disk e made of resilient sheet steel has in the middle a hole corresponding to the cross-section of the square α and at the edge several, for example three, tabs or extensions f bent towards the ratchet wheel d . These press against the ratchet wheel d as soon as the disk e counteracts its suspension pushed up to the annular groove c and rotated in this by about 45 °. In this position, the suspension can no longer move the disk e, and the ratchet wheel d is thus secured against axial displacement. So that the disc e cannot rotate unintentionally, the ratchet wheel has a recess g in the front, into which one of the tabs or extensions f enters with its end.
