dieselben Nachteile auf, wie sie im Patente Nr. 75443 bei Zahnstangenwinden besprochen werden.
Gegenstand vorliegender Erfindung ist nun die Anwendung der in dem genannten Patente beschriebenen Einrichtung auch bei Seil-oder Kettenwinden, um in diesem Falle ebenfalls die Anzahl der Rädervorgelege tunlichst herabzumindern und den Wirkungsgrad der Winden zu erhöhen, ohne jedoch die Einfachheit der Bedienung der Winden weder beim Heben noch beim Senken der Last zu beeinträchtigen.
Die Fig. i und 2 der Zeichnung zeigen eine Seiltrommelwinde, welche mit einer für Ratschenhebelantrieb eingerichteten, selbsttätig wirkenden Reibungshemmung ausgestattet ist.
Der Hebel A arbeitet ebenso wie bei der Winde nach dem erwähnten Patente vermittelst einer umlegbaren Sperrklinke k mit dem als Sperrad ausgebildeten Antriebsteil a der Hemmvorrichtung zusammen, welche auf der Achse der Seiltrommel t sitzt. Die Wirkungsweise ist genau dieselbe wie in dem angeführten Patente beschrieben.
Die Fig. 3 und 4 zeigen ein ganze ähnlich ausgestattete Kettenwinde, bei welcher das Getriebe in dem festhängenden Rahmen eingebaut ist, wogegen bei der Ausführungsform gemäss Fig. 5 und 6 das Getriebe gemeinsam mit der Last gehoben und gesenkt wird, wobei der Hebel h auch in der

EMI1.1
the same disadvantages as discussed in rack and pinion winches in Patent No. 75443.
The subject of the present invention is the use of the device described in the cited patents also in rope or chain winches, in order to reduce the number of gear reduction gears as much as possible and to increase the efficiency of the winches, but without the simplicity of operation of the winches Lifting still has an impact on lowering the load.
FIGS. 1 and 2 of the drawing show a cable drum winch which is equipped with an automatically acting frictional inhibition set up for ratchet lever drive.
As with the winch according to the patent mentioned, the lever A works by means of a reversible pawl k with the drive part a of the locking device, which is designed as a ratchet wheel and sits on the axis of the cable drum t. The mode of operation is exactly the same as described in the cited patent.
3 and 4 show a whole similarly equipped chain winch in which the gear is installed in the fixed frame, whereas in the embodiment according to FIGS. 5 and 6 the gear is raised and lowered together with the load, the lever h also being raised and lowered in the
