Bei den bisherigen Riemenfallhämmern ist der Fallbär an einem Riemen befestigt, welcher auf einer rasch rotirenden Riemscheibe liegt und an seinem freien Ende von einem Arbeiter so kräftig angezogen wird, dafs der Fallbär vermöge der zwischen Riemen und Scheibe auftretenden Reibung gehoben wird, um beim Nachlassen des Zuges am Riemen auf den Ambos niederzufallen.In the previous belt drop hammers, the drop hammers are attached to a belt, which on a rapidly rotating pulley and at its free end by a worker is drawn so strongly that the hawk can get between the belt and the pulley occurring friction is raised to when the tension on the belt is released Falling down anvil.
Bei der nach vorliegender Erfindung construirten und in beiliegender Zeichnung veranschaulichten Hebevorrichtung wirkt an Stelle des Arbeiters eine Rolle p, welche an dem bei Z gelagerten Hebel h angebracht ist. Durch Niederziehen des Hebels h seitens des den Hammer benutzenden Arbeiters wird die Rolle ρ gegen den Riemen r und die Scheibe t gedrückt und dadurch die zur Hebung des Fallbären b erforderliche Reibung erzeugt. Wird der Zug auf den Hebel h nachgelassen, so wird die Rolle ρ durch das Gegengewicht c von dem Riemen r abgehoben und der Fallbär b dadurch zum Niederfallen auf den Ambos α gebracht.In the lifting device constructed according to the present invention and illustrated in the accompanying drawing, a roller p, which is attached to the lever h mounted at Z, acts in place of the worker. By pulling down the lever h on the part of the worker using the hammer, the roller ρ is pressed against the belt r and the pulley t, thereby producing the friction required to lift the falling bear b. If the pull on the lever h is released, the roller ρ is lifted off the belt r by the counterweight c and the falling bear b is thereby brought to fall onto the anvil α .
Die dargestellte Hebevorrichtung kann natürlich constructiv mannigfach geändert werden, ohne dafs dadurch das Wesen vorliegender Erfindung berührt wird.The lifting device shown can of course be changed in many ways constructiv, without affecting the essence of the present invention.
