KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Befestigung von Linsen in ihren Halteringen aus Glas erfolgte bisher durch Kitten. Diese Befestigungsweise leidet, abgesehen von der Umständlichkeit, an dem Übelstande, daß die Linse im Falle ihres Bruches oder im Falle des Bruches des Glasringes nicht ausgewechselt werden kann.The attachment of lenses in their retaining rings made of glass was previously done by cement. This method of fastening suffers, apart from the inconvenience, from the disadvantage that the lens in case of its breakage or in case of breakage of the glass ring is not replaced can be.
Gegenstand der vorliegenden Erfindung ist nun eine neue lösbare Befestigung von Linsen ίο in Glashalteringen, bei welcher statt des Kittens ein für Bolzenbefestigungen bekannter Spannring, der in eine Nut der Linse eingelegt werden kann, benutzt wird.The subject of the present invention is a new releasable attachment of lenses ίο in glass retaining rings, in which instead of the putty one is known for bolt fastenings Tension ring, which can be inserted into a groove in the lens, is used.
Dabei ist der Spannring nicht wie die bekannten Spannringe mit Ausbuchtungen versehen, sondern kreisförmig ausgebildet mit kleinem Querschnitt, um Schatten Wirkungen zu vermeiden.The clamping ring is not provided with bulges like the known clamping rings, but circular with a small cross-section to avoid shadow effects.
In der Zeichnung ist der Erfindungsgegenstand in beispielsweiser Ausführungsform in Fig. I im senkrechten Schnitt, inIn the drawing, the subject matter of the invention is shown in an exemplary embodiment in FIG Fig. I in vertical section, in
Fig. 2 in Seitenansicht mit auseinandergenommenen Teilen, inFig. 2 in side view with disassembled parts, in
Fig. 3 in Aufsicht dargestellt.Fig. 3 shown in plan view.
In die Öffnung des Glasringes c ist die Linse α so eingeschoben, daß ihr Flansch b sich gegen den unteren Glasringrand stützt. In gleicher Höhe mit der oberen Stirnfläche des Glasringes c ist in der Linse α eine Nut d von halbkreisförmigem Querschnitt eingearbeitet, in welche ein kreisförmig gebogener federnder Spanndraht e eingelegt werden kann, derart, daß dieser federnde Spannring, der sich auf der oberen Stirnfläche des Glasringes c auflegt, die Linse fest in die Öffnung dieses Glasringes einpreßt.The lens α is inserted into the opening of the glass ring c in such a way that its flange b is supported against the lower edge of the glass ring. At the same height as the upper end face of the glass ring c , a groove d of semicircular cross-section is incorporated into the lens α , into which a circularly bent resilient tension wire e can be inserted, so that this resilient tension ring, which is located on the upper end face of the glass ring c hangs up, presses the lens firmly into the opening of this glass ring.
