Es kann daher die Welle 8 durch die Kupplung mit dem Schneckengetriebe gekuppelt oder durch Losen der Kupplung, unabhängig von letzterem, frei drehbar gemacht worden, so dass mittels einer an der Wolle sitzenden Handkurbel 15 die Kette auf die auf der Welle sitzende Trommel rascher aufgewickelt werden kann.
Der Schwengel besitzt an seinem Ende ein Kreisbogensegment 16, welches bekanntlich dazu dient, bei jeder Lage des Schwengels die Führung der Kette in achsialer Richtung

bisher geradlinig zur Nachlasswinde geführt, sondern dieselbe ist durch ein zweites, gegenüber dem Segment 16 vorgesehenes, konkav-konvexes Führungsstück 17 und die Rollen 10 und 11 gezwungen, in einem gewundenen Wege zu gleiten. Mit dieser Anordnung wird bezweckt, einerseits beim Rückstosse des Bohrwerkzeuges und dadurch bewirktem Hochschnellen der Kette ein Hochheben oder Springen derselben in dieser Führung zu verhindern, andererseits doch ein leichtes Gleiten ohne grosse Reibung der Kette zu ermöglichen.
PATENT-ANSPRÜCHE : L Ticfbohrkran, dadurch gekennzeichnet, dass auf dom Krangestell oder Bohr- schwengel (2) ein Rehmenhebel (3) drehbar angeordnet ist, an welchen einerseits eine Spannfeder und andererseits die zum Bohrgestänge führende und von einer Nachiass-

The shaft 8 can therefore be coupled to the worm gear by the coupling or made freely rotatable by loosening the coupling, independently of the latter, so that the chain can be wound more quickly onto the drum sitting on the shaft by means of a hand crank 15 attached to the wool can.
The lever has at its end a circular arc segment 16 which, as is known, serves to guide the chain in the axial direction in every position of the lever

hitherto guided in a straight line to the release winch, but the same is forced to slide in a winding path by a second concave-convex guide piece 17 provided opposite the segment 16 and the rollers 10 and 11. The aim of this arrangement is, on the one hand, to prevent lifting or jumping of the same in this guide when the drilling tool is pushed back and the chain jumps up as a result, and on the other hand to allow easy sliding without great friction of the chain.
PATENT CLAIMS: L Ticfbohrkran, characterized in that a frame lever (3) is rotatably arranged on the dome crane frame or drill handle (2), on which a tension spring on the one hand and the one leading to the drill rod and from a follower
