Die bekannten elektrischen Hammer und ähnlichen Werkzeuge mit innerhalb mehrerer Spulen sich hin- und herbewegendem Eisenkern haben eine verhältnismäßig nur kurze Lebensdauer und sind häufig Betriebsstörungen und Ausbesserungen ausgesetzt, weil die beim Umschalten eintretende starke Funkenbildung nicht nur einen Energieverlust, sondern vor allen Dingen eine baldige Zerstörung der ίο empfindlichen Umschaltvorrichtung zur Folge hatte.The well-known electric hammer and similar tools with within several Coils of floating iron core have a relatively short length Lifetime and are often exposed to malfunctions and repairs because of the Switching occurring strong sparking not only a loss of energy, but before all things result in an early destruction of the ίο sensitive switching device would have.
Der Zweck der vorliegenden Erfindung ist nun, die Funkenbildung zu vermeiden und dadurch die Lebensdauer der Werkzeuge zu verlängern.The purpose of the present invention is now to avoid sparking and thereby to extend the life of the tools.
Auf der Zeichnung ist der Erfindungsgegenstand dargestellt, und zwar zeigt:The subject of the invention is shown in the drawing, namely:
Fig. ι einen Längsschnitt des Werkzeuges, Fig. 2 das Schaltungsschema,
Fig. 3 einen Längsschnitt der Schaltvorrichtung, _Fig. Ι a longitudinal section of the tool, Fig. 2 the circuit diagram,
3 shows a longitudinal section of the switching device,
Fig. 4 den Schaltschieber in Schnitt und Ansicht,4 shows the slide switch in section and view,
Fig. 5 einen Schnitt nach der Linie A-A der Fig. 3.FIG. 5 shows a section along the line AA in FIG. 3.
Der Grundgedanke der vorliegenden Er-. findung besteht darin, daß behufs Vermeidung der Funkenbildung die Solenoide aus einzelnen Spulen zusammengesetzt sind, die durch eine eigenartige Steuervorrichtung derart eingeschaltet werden, daß die volle Stromstärke nicht plötzlich durch die ganze Spule, sondern zunächst durch einen Teil derselben und erst dann allmählich durch die ganze Spule geschickt wird. Hierzu kommt die Wirkung der gegenseitigen Induktion der einzelnen Spulenteile, die zur Verringerung der Funkenbildung beiträgt.The basic idea of the present er-. finding is that for the sake of avoidance the sparking the solenoids are composed of individual coils, which are controlled by a peculiar control device be switched on in such a way that the full amperage does not suddenly go through the whole Coil, but first through part of the same and only then gradually through the whole coil is sent. To this comes the effect of the mutual induction individual coil parts that help reduce sparking.
Wie die Zeichnung erkennen läßt, bewegt sich der Anker α des Werkzeuges dadurch in seinem Rohre b, daß er in bekannter Weise abwechselnd in die eine oder andere Spule c oder d hineingezogen wird, die von den Zylindern e und / und den Scheiben g, h und i umgeben sind. An dem Anker α ist die Metallscheibe k befestigt, die den hülsenförmigen Schaltschieber / in an sich bekannter Weise am Ende eines jeden Hubes auf dem Stabe m verschiebt. Letzterer ist in dem Ringe η ein- und feststellbar befestigt.As the drawing shows, the armature α of the tool moves in its tube b in that it is drawn alternately in a known manner into one or the other coil c or d, which is supported by the cylinders e and / and the disks g, h and i are surrounded. The metal disk k is attached to the armature α and moves the sleeve-shaped slide switch / in a manner known per se on the rod m at the end of each stroke. The latter is fixed adjustable and lockable in the ring η.
Auf dem Stabe in, der zusammen mit dem Schieber / die Steuervorrichtung bildet, sind sämtliche Kontakte in Form von Ringen aufgereiht, deren leitende Verbindung durch Verschiebung des Schaltschiebers I erfolgt, wobei die Stromzuleitung in das Innere des Stabes m verlegt ist. Die einzelnen Ringe sind durch Isolationsscheiben ζ voneinander und durch das Isolationsrohr zv von dem Stabe ν getrennt. On the rod in which forms together with the slide / the control device, all contacts are lined up in the form of rings, the conductive connection of which is made by moving the slide switch I , with the power supply being laid inside the rod m. The individual rings are separated from one another by insulating washers ζ and from the rod ν by the insulating tube zv .
Das vordere Ende des Stabes bildet das Kontaktstück 0, welches, wie das Schaltungsschema ergibt, mit dem einen Ende der Spule c und der einen Stromzuführung verbunden ist. Der isolierte Kontaktring r ist mit der Mitte der Spule c verbunden und teilt diese somit in die Hälften C1 und C2- Das Kontaktstück ί ist mit dem anderen Ende der Spule c undThe front end of the rod forms the contact piece 0, which, as the circuit diagram shows, is connected to one end of the coil c and the one power supply. The isolated contact ring r is connected to the center of the coil c and thus divides it into the halves C 1 and C 2 - the contact piece ί is with the other end of the coil c and
