Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Seit Einführung der Federzugwerke an Uhrwerken aller Art ist es als ein grofser Uebelstand empfunden worden, dafs beim Springen der Feder infolge des Rückschlages des Federgehäuses bedeutende Beschädigungen an Radzähnen, Trieben und Achsen vorkommen.Since the introduction of spring-loaded mechanisms in clockworks of all kinds, it has been a great evil felt that when the spring cracks as a result of the kickback of the spring housing Significant damage to gear teeth, drives and axles occurs.
Man hat deshalb in verschiedener Weise versucht, diesem Uebelstande zu begegnen, z. B. dadurch, dafs man die Radzähne nicht mehr scharfkantig, sondern abgerundet herstellte. Die Beschädigungen wurden aber, wenn auch gemindert, doch nicht ganz vermieden. Attempts have therefore been made in various ways to counter this disadvantage, z. B. by the fact that the wheel teeth are no longer made sharp, but rounded. However, the damage was not entirely avoided, even if it was reduced.
Um nun solche Beschädigungen an Uhrwerken, die das Springen der Feder veranlafst, nach Möglichkeit zu verhüten, wird auf Grund vorliegender Erfindung ein besonderes Gesperre, das unter dem Namen »Theilgesperre« bekannt ist, an dem Federhause angebracht. Dieses Theilgesperre besteht aus zwei oder mehreren Sperrkegeln α und b, die so angeordnet sind, dafs, sobald der eine Sperrkegel, beispielsweise Kegel a, um die halbe Zahnhöhe gehoben ist, der andere Sperrkegel (Sperrkegel b) einfällt. Hierdurch wird die Theilung des Sperrrades c verkleinert und damit der Weg des Federhauses d beim Rücksprung im Falle des Zerreifsens der Triebfeder verkürzt und auf diese Weise der Stofs bezw. der Rückschlag des Federgehäuses oder Treibrades f auf die übrigen Uhrwerktheile (Zahnräder, Achsen und Zapfen) aufserordentlich geschwächt. In order to prevent such damage to clockworks, which causes the spring to jump, as far as possible, a special locking mechanism, known as the "partial locking mechanism", is attached to the spring house on the basis of the present invention. This partial lock consists of two or more locking cones α and b, which are arranged so that as soon as one locking cone, for example cone a, is raised by half the tooth height, the other locking cone (locking cone b) engages. As a result, the division of the ratchet wheel c is reduced and thus the path of the barrel d is shortened on return in the event of the mainspring tearing and in this way the material or the kickback of the spring housing or drive wheel f on the other clockwork parts (gears, axles and journals) is extremely weakened.
Um den beschriebenen abwechselnden Eingriff der beiden Sperrkegel α und b mit Erfolg zu erreichen, ist die Anordnung so getroffen, dafs der eine Sperrkegel (Sperrkegel b) etwas länger ist als der andere a, bezw. dafs der Abstand des Drehpunktes χ des Absperrkegels b an der Sperrradmitte ^ etwas gröfser ist als der Abstand des anderen Sperrkegeldrehpunktes y von derselben (Fig. 1).In order to successfully achieve the described alternating engagement of the two locking cones α and b , the arrangement is made so that one locking cone (locking cone b) is slightly longer than the other a, respectively. that the distance of the pivot point χ of the shut-off cone b at the center of the ratchet wheel ^ is somewhat greater than the distance of the other locking cone pivot point y from the same (Fig. 1).
Vortheilhaft ist, das Sperrrad c möglichst in die Mitte der Höhe des Federgehäuses d zu legen, wie in Fig. 2 punktirt angedeutet ist. Bei Taschenuhren werden die Sperrkegel a und b in der Platine g versenkt angeordnet und das Sperrrad in der Mitte der Federtrommel d befestigt (s. Fig. 3 und 4).It is advantageous to place the ratchet wheel c as close as possible to the middle of the height of the spring housing d , as indicated by dotted lines in FIG. In pocket watches, the locking cones a and b are sunk into the plate g and the ratchet wheel is fixed in the center of the spring drum d (see FIGS. 3 and 4).
Bei Federwerken mit feststehender Federtrommel d kann das Sperrrad c direct am Treibrad f befestigt werden. Bei Federwerken für Regulatoren müssen die Sperrkegel α und b in eine verticale Ebene gelegt werden.In the case of spring mechanisms with a fixed spring drum d , the ratchet wheel c can be attached directly to the drive wheel f. In the case of spring mechanisms for regulators, the locking cones α and b must be placed in a vertical plane.
Die Erfindung soll für Uhrwerke aller Art, soweit sie Federwerke besitzen, in Anwendung kommen.The invention is intended to be used for clockworks of all types, insofar as they have spring mechanisms come.
