KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Vorliegende Erfindung betrifft die Anordnung einer zangenartigen Platte neben der Seitenplatte eines Kettengliedes, wodurch vermöge Eingriffes mit einer eingedrehten Nuth am Kopfe des Verbindungsbolzens dieser in seiner Lage festgehalten wird. Durch Spreizung der Zangenplatte mittelst eines Schlüssels kann das Zangenmaul um so viel erweitert werden, dafs sich alsdann der Verbindungsbolzen herausziehen und somit die Kette lösen läfst.The present invention relates to the arrangement of a tong-like plate next to the Side plate of a chain link, as a result of which it engages with a screwed-in groove at the head of the connecting bolt this is held in place. By spreading the pliers plate by means of a wrench can expand the jaws of the pliers by so much that the connecting bolt will then pull out and thus loosen the chain running.
Auf beiliegender Zeichnung istOn the accompanying drawing is
Fig. ι die Seitenansicht eines Kettengliedes der neuen Ausführungsart in Verbindung mit anschliefsenden Kettengliedern,Fig. Ι the side view of a chain link of the new embodiment in connection with subsequent chain links,
Fig. 2 eine gleichartige Ansicht, wobei der mittelst Schlüssels bewerkstelligte Spreizvorgang veranschaulicht wird,2 shows a similar view, with the spreading process carried out by means of a key is illustrated,
Fig. 3 eine Seitenansicht des Schlüssels,3 is a side view of the key,
Fig. 4 die Ansicht des Verbindungsbolzens.4 shows the view of the connecting bolt.
Der Bolzen d (Fig. 4), welcher behufs Lösung der Kette herausziehbar sein soll, ist an dem Kopf d2 mit einer eingedrehten Nuth d3 versehen. Zum Eingriff hiermit sind die von einer Platte b gebildeten, bei b& £>6 ausgekerbten Backen bs £4 bestimmt. Die Platte b ist an der Seite des betreffenden Kettengliedes α unter dem Kopf c des Verbindungsbolzens oder mittelst eines anderen Gelenkzapfens beiläufig drehbar befestigt. Der an den zwei Backenkerben bs bß auslaufende mittlere Schlitz b2 der Platte b ergiebt eine genügende Federung, um eine Spreizung der Backen, die wie Zangen an der Bolzennuth dB eingreifen, zu ermöglichen. Zweckmä'fsig bedient man sich hierzu eines Schlüssels g (Fig. 3), dessen wirksamer Theil g2 elliptischen Querschnitt hat, und welchen man, wie aus Fig. 2 ersichtlich, in den ausgebuchteten Schlitz b2 einführen kann. In der Seitenplatte α des Kettengliedes ist auch ein Ausschnitt h vorgesehen, in den der bei b% eingesteckte Schlüssel hineinragt, und der dazu dient, zu verhüten, dafs der Schlüssel durch zu weites Spreizen die Platte b aus einander sprengt.The bolt d (FIG. 4), which should be able to be pulled out in order to loosen the chain, is provided with a screwed-in groove d 3 on the head d 2 . The jaws b s £ 4 formed by a plate b and notched at b & £> 6 are intended for engagement with this. The plate b is attached to the side of the relevant chain link α under the head c of the connecting bolt or by means of another pivot pin so as to be casually rotatable. The middle slot b 2 of the plate b, which ends at the two jaw notches b s b ß, results in sufficient springiness to allow the jaws, which engage like pliers on the bolt nut d B , to spread. A key g (FIG. 3), the effective part g 2 of which has an elliptical cross-section and which, as can be seen from FIG. 2, can be inserted into the bulged slot b 2 , is expediently used for this purpose. In the side plate α of the chain link there is also a cutout h into which the key inserted at b % protrudes and which serves to prevent the key from splaying the plate b apart by spreading it too far.
Bei der Spreizung der Zangentheile bs b* bilden die Kerben b5 b6 eine dem äufseren Bolzendurchmesser entsprechende gröfsere Oeffnung, so dafs der Bolzen d nach hinten herausgezogen werden kann. Anderenfalls ist jede zufällige Lösung des Eingriffes unmöglich.When the pincer parts b s b * are spread apart, the notches b 5 b 6 form a larger opening corresponding to the outer bolt diameter, so that the bolt d can be pulled out towards the rear. Otherwise any accidental solution to the intervention is impossible.
