Elektrische Handbohrmaschine.
Die Erfindung bezieht sich auf eine elektrische Handbohrmaschine, bei welcher zwischen den'Motor und den Werkzeughalter eine Reibungskupplung eingeschaltet ist, deren Einrückung durch das Ansetzen der Maschine an das Arbeitsstück erfolgt. Die Erfindung besteht darin, dass zwischen den mit dem Werkzeughalter verbundenen beweglichen Teil der Kupplung und das feststehende Kupplungsgehäuse eine Feder eingeschaltet ist, welche die Kupplungsteile ausser Eingriff bringt und hiebei den Werkzeughalter an das feststehende Gehäuse drückt und somit abbremst.
Die Zeichnung zeigt eine beispielsweise Ausführungsform des Werkzeughalterendes einer Bohrmaschine gemäss der Erfindung zum Teil im Schnitt.
An dem in üblicher Weise mit einem Handgriff versehenen Motorgehäuse S ist ein langer Hals 4 vorgesehen, dessen Ende das Kupplungsgehäuse 3 bildet, in welchem der Werkzeughalter 5 gelagert ist. Die beiden Kupplungshälften, von denen die eine am Werkzeughalter, die andere an der Maschinenspindel sitzt, werden durch eine Feder 6 ausser Eingriff gehalten, die sich gegen den beweglichen Werkzeughalter und gegen das feststehende Gehäuse abstützt. Der Werkzeughalter wird somit ausser Gebrauch gegen das feststehende Kupplungsgehäuse gedrückt, wodurch beim Abheben der Maschine nicht nur ein Entkuppeln, sondern gleichzeitig auch durch das Abbremsen ein sofortiges Stillsetzen des Werkzeuges erfolgt.

Electric hand drill.
The invention relates to an electric hand drill in which a friction clutch is switched on between the motor and the tool holder, the engagement of which occurs when the machine is attached to the workpiece. The invention consists in that a spring is connected between the movable part of the clutch connected to the tool holder and the stationary clutch housing, which disengages the clutch parts and presses the tool holder against the stationary housing and thus brakes it.
The drawing shows an example embodiment of the tool holder end of a drilling machine according to the invention, partly in section.
On the motor housing S, which is provided in the usual way with a handle, a long neck 4 is provided, the end of which forms the coupling housing 3 in which the tool holder 5 is mounted. The two coupling halves, one of which sits on the tool holder and the other on the machine spindle, are held out of engagement by a spring 6 which is supported against the movable tool holder and against the stationary housing. The tool holder is thus pressed against the stationary coupling housing when not in use, so that when the machine is lifted, not only is it uncoupled, but at the same time the tool is stopped immediately due to braking.
