Verschlursvorrichtung an Sicherheitslampen, welche nur nach Zertrümmerung von Glasstäbchen ein Oeffhen derselben zuläßt.Accelerating device on safety lights, which only after the Glass rods allow them to be opened.
Patentirt im Deutschen Reiche vom 14. Februar 1880 ab.Patented in the German Empire on February 14, 1880.
Die in der Zeichnung angegebene Verschlufsvorrichtung einer Davy'sehen Sicherheitslampe besteht in folgendem:The locking device of a Davy's watch safety lamp indicated in the drawing consists of the following:
Um das Gefäfs der Lampe, welches zur Aufnahme des Brennmaterials dient, und auf dem der Brenner mit dem Cylinderhalter sitzt, befindet sich der fest angelöthete Ring A, an dem zwei Krampen α und a1 angenietet sind.Around the vessel of the lamp, which is used to hold the fuel and on which the burner with the cylinder holder sits, is the firmly soldered ring A to which two staples α and a 1 are riveted.
Der obere Theil der Lampe, bestehend aus dem Drahtgestell C, an welchem das Sicherheitssieb, der Schornstein und der Ring D durch Niete und Löthung befestigt sind, trägt unten die angenieteten Riegel B und B'. The upper part of the lamp, consisting of the wire frame C, to which the safety screen, the chimney, and the ring D are fastened by rivets and soldering, bears the riveted bolts B and B 'below.
In diesen Riegeln liegen nun in einer Vertiefung die vorn mit Haken versehenen Federn c und c1, die je ein aus sprödem durch plötzliche Abkühlung gehärtetem Glas bestehende Stäbchen umfassen können. Diese Stäbchen stecken in dem unteren Ring A, in den Löchern d bezw.' d1 und ragen um die Höhe der Federn aus dem Ring A heraus. The springs c and c 1 , which are provided with hooks at the front and which can each comprise a rod made of brittle glass hardened by sudden cooling, now lie in a recess. These sticks are in the lower ring A, in the holes d and ' d 1 and protrude from ring A by the height of the springs.
Nachdem die Lampe angezündet ist, wird der Cylinder aufgesteckt. In die Löcher d und dl werden zwei Glasstäbchen gesteckt, und dann der obere Theil so aufgesetzt, dafs diese Stäbchen in die vor' den Federhäkchen befindlichen Oeffnungen hineinkommen. Man dreht nun den ganzen oberen Theil so herum, dafs die Riegelansätze e und ei in die Krampen α und al hineingehen, wobei gleichzeitig die Federhäkchen hinter die Glasstäbchen schnappen.After the lamp is lit, the cylinder is put on. Two small glass sticks are inserted into holes d and d 1 , and the upper part is then placed on in such a way that these sticks enter the openings in front of the spring hooks. The whole upper part is now turned around so that the locking lugs e and e i go into the clamps α and a l , while at the same time the spring hooks snap behind the glass rods.
Ein Oeffnen des Verschlusses ist deswegen nur noch dadurch zu ermöglichen, dafs irgend etwas an demselben zerbrochen wird.An opening of the lock can therefore only be made possible by somehow something is broken on the same.
Der zum Oeffnen Befugte öffnet die Lampe dadurch, dafs er mit einem Diamantsplitter, wie solcher von den Glasern gebraucht wird, die Glasstäbchen von unten, wo die Durchbohrungen d und d' enger als die Stäbchen dick sind, so dafs diese nicht herausfallen können, ritzt. Das Stäbchen wird sofort in kleinere Stücke zerspringen und der Verschlufs kann geöffnet werden.The person authorized to open the lamp opens the lamp by scratching the small glass rods from below with a diamond splinter, such as that used by glasses, where the holes d and d 'are narrower than the small rods so that they cannot fall out . The stick will immediately shatter into smaller pieces and the closure can be opened.
