KAISERLICHESIMPERIAL
PATENTAMPATENTAM
Es hat sich herausgestellt, dafs die im Haupt- und Zusatz-Patent angegebenen weichen Gummibälle und Kugeln für Lampen nicht vortheilhaft sind, indem dieselben durch OeI angegriffen werden und dadurch eine sichere Wirkungsweise ausgeschlossen ist. Um letztere für alle Fälle sicher zu stellen, sollen statt der weichen Scheibchen oder Kugeln, wie im I. Zusatz-Patent beschrieben, Metallkugeln, und zwar hauptsächlich solche aus Stahl angewendet werden. Es genügen im allgemeinen für eine Einrichtung drei Kugeln. Dieselben müssen zur Sicherung ihrer Lage auf dem Kolben (g) in Aussparungen P, Fig. 1 und 2, oder zwischen Stegen P, Fig. 3, gehalten werden.It has been found that the soft rubber balls and spheres specified in the main and additional patents are not advantageous for lamps in that they are attacked by oil and a safe mode of operation is thereby excluded. In order to ensure the latter for all cases, metal balls, mainly those made of steel, should be used instead of the soft discs or balls, as described in the 1st additional patent. In general, three balls are sufficient for one device. To secure their position on the piston (g), they must be held in recesses P, FIGS. 1 and 2, or between webs P, FIG. 3.
Statt eines Kolbens, der sich in einer Röhre oder Führung α bewegt, kann die Einrichtung auch nach Fig. 5 hergestellt werden.Instead of a piston which moves in a tube or guide α , the device can also be produced according to FIG. 5.
Diese Figur zeigt auf je einer Hälfte die Einrichtung, welche den Grundrissen Fig. 3 und 4 entspricht und nur in der Art der Auslösung eine kleine Verschiedenheit aufweist. Hier umfafst der Kolben die Röhre oder Führung α und dementsprechend gleitet auch die Röhre b über dieser oder α verschiebt sich in ihr. Der Kolben oder nunmehr eigentlich Hülse g erhält die konische Wandung d, während die Kugeln auf einem durch Stifte 1 oder Hebel 2 unterstützten Kugelträger g : in der oben beschriebenen Weise aufliegen. Die Wirkung dieser Einrichtung ist leicht erklärlich. Vermöge des Eigengewichts oder der Belastung des Rohres α wird dasselbe dadurch, dafs die Kugeln am Konus d herabgleiten, in seiner jeweiligen Lage. festgehalten. Die Auslösung erfolgt durch Heben der Kugeln, indem man ihren Kugelträger gl mittelst des konischen Stiftes ι oder des Hebels 2 in die Höhe schiebt.This figure shows the device on one half, which corresponds to the floor plans in FIGS. 3 and 4 and only differs slightly in the type of triggering. Here the piston embraces the tube or guide α and accordingly the tube b also slides over this or α shifts in it. The piston or now actually sleeve g d receives the conical wall, while the balls g on a supported by pins 1 and lever 2 ball carrier: rest in the manner described above. The effect of this facility is easy to explain. By virtue of its own weight or the load on the pipe α , the same is achieved by the fact that the balls slide down the cone d in its respective position. held. The triggering takes place by lifting the balls by pushing their ball carrier g l upwards by means of the conical pin ι or the lever 2.
Die Auslösung der Einrichtung von Fig. 1 geschieht, wie in dem Haupt- und I. Zusatz-Patent beschrieben.The triggering of the device of FIG. 1 occurs as in the main and I supplementary patent described.
Fig. 6 zeigt noch die Anordnung für .eine feststehende Röhre oder Stange a. Hier gleitet die Hülse g, welche in diesem Fall der tragende Theil ist, auf und ab. Die Feststellung geschieht wie oben beschrieben, nur ist der Konus d umgekehrt. Dementsprechend ist der Kugelträ'ger g1 durch eine Feder beständig nach aufwärts gedrückt. Die Auslösung erfolgt dann durch Abwärtsdrücken des Kugelträgers.Fig. 6 shows the arrangement for .eine fixed tube or rod a. Here the sleeve g, which in this case is the supporting part, slides up and down. The determination is made as described above, only the cone d is reversed. Accordingly, the ball carrier g 1 is constantly pressed upwards by a spring. It is then released by pushing the ball carrier downwards.
Soll vermieden werden, dafs die Kugeln, z. B. bei Führungen aus weicherem Metall, beim öfteren Einklemmen Eindrücke hinterlassen, so braucht vor dieselbe nur eine bewegliche Scheibe, Platte etc. angeordnet werden. In Fig. 7 ist die der Fig. 1 entsprechende Anordnung gezeichnet, in Fig. 8 in kleinerem Mafsstab die der Fig. 5 entsprechende.Should be avoided that the balls, z. B. for guides made of softer metal, leave impressions if it is often pinched, so only a movable one needs to be in front of it Disc, plate, etc. are arranged. In FIG. 7 the arrangement corresponding to FIG. 1 is shown drawn, in Fig. 8 on a smaller scale that of FIG. 5 corresponding.
Es ist daraus ersichtlich, dafs an der Stelle, wo die Kugeln gegen die Führungswand liegen (entgegengesetzt dem Konus), eine Platte 7 eingeschaltet ist, also eine Verletzung der Wandung ausgeschlossen wird.It can be seen from this that at the point where the balls lie against the guide wall (opposite to the cone), a plate 7 is switched on, so an injury to the wall is excluded.
