KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

In beiliegender Zeichnung ist eine Schießeinrichtung dargestellt, die auf demselben Grundgedanken beruht, welcher in dem Patent 117469 zum Ausdruck gebracht worden, ist, sich aber dadurch wesentlich von jener Einrichtung unterscheidet, dafs auch für ein gewöhnliches Riegelschlofs Zuhaltungen mit geschlossenen Fenstern verwendet werden. Um diese Ver-Avendung zu ermöglichen und die Zuhaltungsfenster beliebig einstellen zu können, wird der Sperrstift quer zum Riegel beweglich angeordnet. Durch die vom Schlüsselbart bewirkte Drehung eines Getriebes wird der Sperrstift, der mit Gewinde versehen ist, beim Aufsperren aus den Zuhaltungsöffnungen 21 herausgeschraubt und nach Zurückführung der Zuhaltungen in ihre Ruhestellung wiederum durch eine vom Schlüsselbart eingeleitete Drehung des Getriebes in die Zuhaltungsöifnungen hineingeschraubt. In the accompanying drawing is a shooting device which is based on the same principle used in patent 117469 has been expressed, but is thereby essentially different from that institution distinguishes that tumblers with closed locks also for an ordinary bolt lock Windows are used. To enable this use and the guard locking window To be able to adjust as desired, the locking pin is arranged to be movable transversely to the bolt. Through the rotation of a gear caused by the key bit, the locking pin, which is provided with a thread, unscrewed from the tumbler openings 21 when unlocking and after the tumblers have been returned to their rest position, again by a rotation initiated by the key bit of the gearbox screwed into the tumbler openings.

Die in die Zeichnung eingeschriebenen Hinweisungszeichen ι bis 17 haben gleiche Bedeutung, wie dieselben Zeichen in den Figuren des Haupt-Patentes.The symbols ι to 17 inscribed in the drawing have the same meaning, like the same characters in the figures of the main patent.

Zu den aus dem Haupt-Patent bereits bekannten Zahnsegmenten 16¹, 16², 16³, welche sämmtlich um den Stift 17 schwingen, tritt hier noch ein besonders gestaltetes Zahnsegment 25, das um den Stift 26 schwingt, hinzu. ■ Während aber der Stift 17 in dem Schlofsblech 2 eingenietet ist, ist der Stift 26 in dem Riegelschafte 24 befestigt, so dafs also das Zahnsegment 25 mit dem ebenfalls im Riegelschaft gelagerten Zahnrädchen 27 an der Bewegung des Riegels 24 theilnimmt. Die Lagerung des Rädchens 27 ist in der Weise gedacht, dafs ein an seiner Rückseite befindlicher Kreisring 28 in eine Kreisnuth des Riegelschaftes 24 (Fig. 4) hineinpafst. ^{To the toothed segments 16 1} , 16 ² , 16 ³ already known from the main patent, which all swing around the pin 17, a specially designed toothed segment 25, which swings around the pin 26, is added. While the pin 17 is riveted into the lock plate 2, the pin 26 is fastened in the bolt shaft 24, so that the toothed segment 25 with the toothed wheel 27, which is also mounted in the bolt shaft, participates in the movement of the bolt 24. The mounting of the little wheel 27 is designed in such a way that a circular ring 28 located on its rear side fits into a circular groove of the locking shaft 24 (FIG. 4).

Der zuhaltende Stift 10 kann zwar dieselbe, durch abgestufte Kreisringe gekennzeichnete Form wie nach Fig. 1 des Haupt-Patentes haben; er ist aber nicht an diese Ausführungsform gebunden, sondern in beiliegender Zeichnung mit axialen Längsrippen gedacht, also von der Form,, wie die kleinen aus Stahl gefertigten Triebstifte, die in der Uhrmacherei Verwendung finden und billig zu haben sind. Am unteren Ende dieses gezahnten Stiftes 10 ist eine Scheibe 29 starr befestigt, die an ihrem Umfange ein mehrgängiges Gewinde trägt. Mit diesem Gewinde ist der Stift 10,29 in das Muttergewinde des im Riegelschaft 24 befindlichen Loches 30 eingepafst. Das Zahnrädchen 27 ist mit einem sternförmigen Centralloch versehen, durch welches der Zapfen 10 leicht passend hindurchtritt.The pin 10 to be held can be the same, marked by graduated circular rings Have the shape of Figure 1 of the main patent; however, it is not tied to this embodiment, but rather in the accompanying drawing conceived with axial longitudinal ribs, so of the shape, like the small ones made of steel Drive pins that are used in watchmaking and can be obtained cheaply. At the lower end of this toothed pin 10, a disc 29 is rigidly attached to her Carries a multi-start thread. With this thread the pin 10.29 is in the Nut thread of the hole 30 located in the bolt shank 24. The cogwheel 27 is provided with a star-shaped central hole through which the pin 10 easily fits through.

Wird daher das grofse Zahnsegment 25 durch den Schlüsselbart ausgehoben, so dreht sich das mit ihm in Eingriff stehende Räd-Therefore, if the large tooth segment 25 is lifted out by the key bit, it rotates the gear engaged with it

Claims

Chen 27 and in this way screws the pin 10, 29 so deeply into the bolt shaft that it moves from the position of FIG. 2 to the position of FIG. The openings 211 ^ i2, 213 of the tumblers get the circular shape evident from FIGS. 4 and 5 of the main patent only when the pin to be locked has the stepped disk shape of the main patent. This facility is also possible with the present additional patent. If, however, the pin 10 to be locked is provided with longitudinal ribs, as shown in the accompanying drawing, then the locking openings 211, 212, 213 (FIGS. 1, 3 and 5) are oval in shape and each have a tooth 31 on their two narrow sides , 32, 35, which is intended to intervene in the axial Grooves of the pin 10 and an untimely BEZW. to prevent unauthorized rotation of the pen ι ο. In FIG. 5, the tooth 32 engages in the locking mechanism 10. The toothed segments 16 are held in the direction of the arrow 33 and therefore the tumblers are held in the direction of the arrow 34 by springs, which are not entered in the drawing. In the closed position, all tumblers are positioned so that the tooth 35 engages in the gear 10 and in this way causes the pin 10, 29 to neither rotate nor screw into the bolt hole 30. If, however, an attempt is made to open the key with an incorrect key bit, which is too long, the position shown in FIG. 5 arises, the tooth 32 engaging in the gear 10 and again preventing rotation. Should an attempted break-in succeed in finally finding a key bit which lifts all tumblers 161, 162, 163 into the correct position (in the case shown in the drawing three), so that neither the tooth 32 nor the tooth 35 can prevent the rotation of the pin 10, the point of the beard which digs out the segment 25 must also have exactly the correct length. Because if this is too short, the pin 10.29 is not screwed deep enough into the locking hole 30 to free the last of the tumblers 141, and if it is too long, then the pin 10.29 is screwed down so deep that that the thread part 29 moves into the recess 36 (Fig. 4 of the lock plate 2). In this state, the bolt is no longer locked by the tumblers 14, but it is by the pin 10, 29. are indicated by the dash-dotted lines abcd. Position a: The key is inserted into the keyhole 12. It is turned to the left in the direction of the arrow drawn in FIG. Position b: The key bit touches segment 161 at point 37 and lifts it from position Fig. 1 to position Fig. 3 and 5. Depending on the length of the different key bit teeth, segment 161 is raised so high that the center of either the Hole 21l or one of the two other holes 212, 213 with the center of the pin 10 occurs at the same height, as indicated in FIG. 3. Position c: The tumblers 16, of which, by the way, in order not to impair the clarity of the drawing, only the lowest 161 is drawn in FIGS. 1, 3 and 5, remain immovable in their position (FIG. 3) because the key bit now strokes from point 37 in the direction of the arrow drawn at 37 (FIG. 3) on an arc of a circle that remains concentric to the key axis. The toothed segment 25 begins to rise and, as a result of its engagement with the wheel 27, screws the pin 10, 29 down into its recess 30. The bolt 24 is now free. Position d: The key bit touches the left inner flank of the attack and pushes the bolt from position Fig. 1 into position Fig. 5. When the key bit is now further rotated, the pin 10, 29 returns to its highest position shown in FIG. It is now no longer outside the tumblers, as in FIG. 1, but in different holes 21 of tumblers 14 (FIG. 5). The re-opening of the lock by turning the key bit to the right takes place in a completely analogous manner, as described above. Sponsorship τ claims:

1. Key with several different keys, but only with the key used when closing the lock that can be opened again by patent 117469 protected species, characterized in that the locking pin 10 arranged on the bolt out of the closed tumbler windows and into a cavity 30 of the bolt shaft 24 is movable into it.
