KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die vorliegende Erfindung betrifft eine Vorrichtung, um Schutzglocken für elektrische Glühlampen wasserdicht und leicht lösbar zu befestigen.The present invention relates to a device to protect bells for electrical Light bulbs can be attached waterproof and easily detachable.
Bisher wurden hierzu Verschraubungen benutzt. Es traten jedoch hierbei Oxydationen in den Gewindegängen und dadurch ein Festsetzen der Glocken ein, wodurch das Abnehmen erschwert und auch die Schutzglocke selbst leicht der Zerstörung ausgesetzt wurde.So far, screw connections have been used for this. However, it did oxidations in the threads and thereby a seizing of the bells, whereby the decrease difficult and the protective bell itself was easily exposed to destruction.
Bei vorliegender Anordnung sind Verschraubungen oder dergl. vermieden. Das Befestigen der Schutzglocke, deren oberer Rand dabei gegen das Dichtungsmittel der Befestigungskappe geprefst wird, erfolgt mittels federnder Druckbügel, deren Anschlufs durch einfachen Druck der Finger ebenso leicht und sicher bewerkstelligt wie gelöst werden kann.In the present arrangement, screw connections or the like are avoided. The fastening the protective bell, the upper edge of which against the sealing means of the fastening cap is pressed, is done by means of resilient pressure brackets, which can be connected just as easily and simply by simply pressing the finger safely accomplished how can be solved.
Die Einrichtung ist folgende:The facility is as follows:
An der Schutzglocke befindet sich ein Flantsch mit Falz /; in denselben ist ein Draht- bezw. Metallring c gelegt, an welchem federnde Verschlufsbügel b beweglich befestigt sind. An die aus beliebigem Material gefertigte Kappe a mit Dichtungsring d wird die Glocke leicht angedrückt und durch Ueberdrücken der Klammern befestigt.On the protective bell there is a flange with a seam /; in the same is a wire or. Metal ring c placed on which resilient locking bracket b are movably attached. The bell is pressed lightly onto the cap a with sealing ring d made of any material and fastened by pressing over the clamps.
Die Vortheile dieser Befestigung sind folgende: The advantages of this fortification are as follows:
Durch Vermeidung von Verschraubungen ist das durch Oxydation der in einander greifenden Theile oder Bajonnetverschlüsse (s. die englischen Patentschriften 420 vom Jahre 1893 und 11566 vom Jahre 1896) herbeigeführte Festsetzen der Glocken beseitigt.By avoiding screw connections, this is due to oxidation of the interlocking ones Parts or bayonet locks (see English patents 420 from 1893 and 11566 from 1896) Fixing the bells eliminated.
Während bei den bisherigen Einrichtungen das Befestigen und Abnehmen der Glocke durch ungenaues Passen der Gewindetheile erschwert wird, auch häufig die durch Gips oder Kitt hergestellte Verbindung sich löst und bei Schutzglocken mit angegossenem Gewinde die Kappe sehr leicht beschädigt wird, sind alle diese Mängel bei der vorliegenden Einrichtung durch die gewählte Form der an sich allgemein bekannten federnden Verschlufsbügel vermieden.While with the previous facilities the attachment and removal of the bell is made more difficult by imprecise fitting of the thread parts, often also by plaster of paris or The connection made by putty loosens and, in the case of protective bells with a cast thread, the Cap is very easily damaged, all of these are deficiencies in the present device by the selected shape of the generally known resilient locking bracket avoided.
