PATENTAMTPATENT OFFICE
Auf dem in der Hülse α verschiebbaren durch die Spiralfeder i gehobenen, mit den Klemmbacken hs versehenen Bleiminenrohr h, Fig. i, sitzt eine verschiebbare Kapsel bezw. Hülse K, welche an ihrem oberen Ende K1 die Gleitfläche für die Greifer m bildet und mit ihrem unteren Ende K2 über den Klemmbacken hs liegt. Die Hülse K wird durch eine Spiralfeder b abwärts gegen die Klemmbacken gedrückt und hierdurch das aus den Klemmbacken herausragende Blei e bei Nichtgebrauch so gehalten, dafs es nicht herausfallen kann. Wird das Rohr h durch Druck auf den Rohrkopf h3 vorgeschoben, so gelangen die Greifer m hinter das obere Ende K1 der Hülse, Fig. 2, und stellen (sobald der Druck auf h3 aufhört) die Hülse K fest. Die Hülse verhindert dann ihrerseits an ihrem unteren Ende K2 das Zurückweichen von h und bewirkt hierbei zugleich das Festklemmen des Bleies e, so dafs das letztere benutzt werden kann.On the in the sleeve α displaceable by the spiral spring i , provided with the clamping jaws h s lead lead tube h, Fig. I, sits a displaceable capsule respectively. Sleeve K, which forms the sliding surface for the gripper m at its upper end K 1 and lies with its lower end K 2 over the clamping jaws h s. The sleeve K is pressed downwards against the clamping jaws by a spiral spring b and as a result the lead e protruding from the clamping jaws is held in such a way that it cannot fall out when not in use. If the tube h is pushed forward by pressure on the tube head h 3 , the grippers m get behind the upper end K 1 of the sleeve, FIG. 2, and (as soon as the pressure on h 3 ceases) fix the sleeve K. The sleeve then in turn prevents h at its lower end K 2 from retreating and at the same time causes the lead e to be clamped so that the latter can be used.
Bricht das Blei ab oder will man das Rohr h frisch füllen, so werden die Klemmbacken ha durch starken Druck auf h3, wodurch das Rohr h aus der in der äufseren Hülse α festgehaltenen Hülse K weiter hervorgeschoben wird, geöffnet, Fig. 3.If the lead breaks off or if the tube h is to be freshly filled, the clamping jaws h a are opened by strong pressure on h 3 , whereby the tube h is pushed further out of the sleeve K held in the outer sleeve α, FIG. 3.
Der Halter ist hier mit einem in der Patentschrift No. 35867 beschriebenen Auslösungsring η versehen. The holder is here with one of the patent no. 35867 described release ring η provided.
