Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die vorliegende Erfindung ist eine Vorrichtung zum Füllen von Fahrradschläuchen mit comprimirtem Gas oder mit atmosphärischer Luft.The present invention is an apparatus for filling bicycle inner tubes with compressed gas or atmospheric air.
Aehnliche Vorrichtungen sind bereits durch die englische Patentschrift 24629 aus dem Jahre 1897 bekannt geworden. Von dieser Einrichtung unterscheidet sich die vorliegende dadurch, dafs bei ihr die Wandung des Pumpencylinders zur Aufnahme des comprimirten Gases hohl ausgebildet ist. Beide, Hohlräume, der Pumpencylinder und der Gasraum, haben besondere Austrittskanäle, welche so angeordnet sind, dafs nöthigenfalls ein gleichzeitiges Füllen zweier Reifen möglich ist.Similar devices are already through the English patent specification 24629 from the In 1897. The present one differs from this facility in that with it the wall of the pump cylinder for receiving the compressed gas is hollow. Both cavities, the pump cylinder and the gas space, have special ones Outlet channels which are arranged in such a way that, if necessary, simultaneous filling two tires is possible.
Fig. ι der beiliegenden Zeichnung zeigt einen Längsschnitt durch die Vorrichtung undFig. Ι the accompanying drawing shows a longitudinal section through the device and
Fig. 2 eine Ansicht derselben in verkleinertem Mafsstabe mit aufgeschraubtem Handgriff.2 shows a view of the same on a reduced scale with the handle screwed on.
Der Pumpencylinder α dient als Behälter für das comprimirte Gas. Zu diesem Zwecke sind seine Wandungen hohl. Der Hohlraum hat am unteren Ende einen Austrittskanal d, welcher mit einem Abschlufsventil h versehen ist. In dem Kanal d befindet sich ein Gewinde g, mit welchem der Anschlufs an den Fahrradschlauch hergestellt werden- kann, b ist der Pumpenkolben. Derselbe kann mit Hülfe des Griffes/, welcher für gewöhnlich in demselben sich befindet, bewegt werden. Der Boden des Kolbens b besitzt ein Klappenventil i\ c ist der Luftaustrittstutzen der Pumpe.The pump cylinder α serves as a container for the compressed gas. For this purpose, its walls are hollow. The cavity has an outlet channel d at the lower end, which is provided with a shut-off valve h . In the channel d there is a thread g with which the connection to the bicycle tube can be made, b is the pump piston. It can be moved with the help of the handle / which is usually in it. The bottom of piston b has a flap valve i \ c is the air outlet of the pump.
