Description

Die Erfindung betrifft ein Mundstück mit Klopfer für Saugrüssel, bei dem gemäß dem Hauptpatent 520 622 auf dem Mundstück eine elektromagnetische Antriebsvorrichtung für den Klopfer angeordnet ist. Erfindungsgemäß schwingt der Schwinghebel für die Klopfvorrichtung um einen elastisch in sich verdrehbaren Gummikörper, wodurch sowohl die für die Umschaltung des Elektromagneten benötigte Zug- bzw. Druckfeder erspart wird als auch Klappergeräusche des Schwinghebels vermieden werden. Zweckmäßig befestigt man denSchwinghebel an einem eingespannten Gummikörper oder umgibt einen fest eingespannten Flachstab, beispielsweise aus Metall, mit einem Gummikörper, an dem das Hebelende befestigt wird. Es ist bereits bekannt, daß man bei der Klaviertastenlagerung die Taste auf der Schwingachse zwecks Vermeidung des Klapperns mit einer Filzbüchse umgeben hat.The invention relates to a mouthpiece with knocker for proboscis, in which according to the Main patent 520 622 on the mouthpiece an electromagnetic drive device for the Knocker is arranged. According to the invention, the rocking lever for the knocking device swings around an elastically twistable rubber body, whereby both the required for switching the electromagnet Tension and compression springs are saved and rattling noises of the rocker arm are avoided will. The rocker arm is expediently attached to a clamped rubber body or surrounds a firmly clamped flat bar, for example made of metal, with a Rubber body to which the end of the lever is attached. It is already known that one When positioning the piano keys, place the key on the pivot axis in order to avoid rattling surrounded with a felt sleeve.

In der Zeichnung ist eine Ausführungsform der Vorrichtung dargestellt. Das etwa mit einem Stutzen α für den Anschluß des Schlauchs versehene Mundstück δ trägt einen Elektromagneten c, dessen Anker e an dem mit einer Klopfleiste oder Bürste η versehenen Schwingbügel g befestigt ist. In der Ruhelage berührt das Kontaktstück i des Hebels das fest angeordnete Kontaktstück k, so daß der Strom geschlossen ist, während in bekannter Weise die Unterbrechung erfolgt, sobald der Elektromagnet c den Anker e anzieht. Die Schwingachse des Hebels ist nun wie folgt ausgebildet: Ein seitlich fest eingespanntes Flacheisen fi ist von einem Gummikörper r umgeben; es sind beispielsweise zwei Hälften des Gummikörpers aufvulkanisiert. Dieser Gummikörper wird von dem Ende gx des Bügels fest umschlossen. Die Schwingung des Hebels erfolgt somit unter Verdrehung des Gummikörpers in sich. Zur Milderung des durch das Anschlagen des Hebels entstehenden Geräusches dienen die Gummipuffer s und r, die am Gehäuse befestigt sind. Gegen den Puffer s schlägt die Abbiegung u des Hebels.In the drawing, an embodiment of the device is shown. The mouthpiece δ, which is provided with a nozzle α for connecting the hose, carries an electromagnet c, the armature e of which is attached to the swing arm g which is provided with a tapping strip or brush η. In the rest position, the contact piece i of the lever touches the fixed contact piece k, so that the current is closed, while the interruption takes place in a known manner as soon as the electromagnet c attracts the armature e. The swing axis of the lever is now designed as follows: A flat iron fi firmly clamped at the side is surrounded by a rubber body r ; For example, two halves of the rubber body are vulcanized on. This rubber body is firmly enclosed by the end g x of the bracket. The oscillation of the lever thus takes place while the rubber body is twisted. The rubber buffers s and r, which are attached to the housing, are used to reduce the noise caused by hitting the lever. The bend u of the lever strikes against the buffer s.
