KAISERLICHESIMPERIAL
■PATENTAMT.■ PATENT OFFICE.
Durch vorliegende Erfindung werden bekannte Schlauchpumpen, deren Schlauch durch um die Antriebswelle und um sich selbst-rotierende Quetschrollen fortschreitend zusammengequetscht wird, zwecks Verwendung als Spielzeugpumpen dadurch wesentlich vereinfacht und verbilligt, daß das Ausquetschen des Schlauches anstatt durch in starren Armen gelagerte Rollen durch außen gebogene, um ίο die Antriebswelle gewundene und durch diese geschobene flache Federarme erfolgt.The present invention known peristaltic pumps, the hose by progressively squeezed together around the drive shaft and around self-rotating squeegee rollers is, for the purpose of using as toy pumps, significantly simplified and cheaper in that the squeezing out of the Hose instead of rollers mounted in rigid arms by bent outwardly to ίο the drive shaft is wound and flat spring arms pushed through it.
Auf der Zeichnung ist ein Ausführungsbeispiel der neuen Spielzeugpumpe inIn the drawing, an embodiment of the new toy pump is shown in FIG
Fig. 1 im senkrechten, und in
Fig. 2 im wagerechten Mittelschnitt dargestellt. Fig. 1 in the vertical, and in
Fig. 2 shown in the horizontal center section.
In bekannter Weise ist in ein unten zylindrisches Gehäuse α ein die Saugleitung b mit der Druckleitung c verbindender Gummi- o. dgl. Schlauch d eingelegt, der bisher von der Antriebsachse f aus durch starre Arme und in diesen gelagerte Rollen von der Saugleitung zur Druckleitung fortschreitend zusammengequetscht wurde. Der. Erfindung entsprechend sind statt der starren Quetschteile außen gebogene Federarme g vorgesehen, die um die Antriebswelle gewunden und durch einen Längsschlitz derselben gesteckt sind, so daß sie mittels eines einzigen Metallstreifens hergestellt und auf der Welle befestigt werden können. Zum Schütze gegen zu rasche Abnutzung des Schlauches durch Reibung ist zwischen diesem und den Quetscharmen ein loses Schutzband k aus Leinwand-, Baumwolle- o. dgl. Gewebe oder aus Leder angeordnet. In a known manner, a rubber or similar hose d connecting the suction line b to the pressure line c is inserted into a bottom cylindrical housing α , which has hitherto progressed from the drive axis f through rigid arms and rollers mounted in these from the suction line to the pressure line was squeezed. Of the. In accordance with the invention, instead of the rigid crimped parts, externally bent spring arms g are provided which are wound around the drive shaft and inserted through a longitudinal slot of the same so that they can be produced by means of a single metal strip and fastened on the shaft. To protect against excessive wear of the hose due to friction, a loose protective band k made of canvas, cotton or similar fabric or leather is arranged between it and the squeeze arms.
