Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bei dem Schlagbaum des Patentes Nr. 61374 kann es vorkommen, dafs der Schrankenbaum E, während er durch Drehung der Kettenrolle L niedergelegt wird, unabhängig von der Bewegung der Kettenrolle durch Winddruck mit Gewalt niedergeworfen wird, weil er ja während seiner Abwartsbewegung nicht besonders mit der Kettenrolle gekuppelt ist. Ein solches Vorkommnifs kann aber zu Beschädigungen an der Einrichtung selbst oder gar zu Verletzungen von lebenden Wesen führen.With the barrier arm of patent No. 61374 it can happen that the barrier arm E, while it is being lowered by the rotation of the chain roller L , is forcibly thrown down by wind pressure regardless of the movement of the chain roller, because during its downward movement it is not particularly affected by the Chain roller is coupled. Such an occurrence can lead to damage to the facility itself or even to injuries to living beings.
Um solche Unglücksfälle zu verhüten, ist auf dem Schrankenbaum E eine Sperrklinke M angebracht, welche durch ein Gegengewicht M1 hinter den entsprechend verlängerten Knaggen 0 gezogen wird, Fig. 1, durch welchen unter Vermittelung des Hebels P bezw. mehrerer Hebel und des Knaggens η der Schrankenbaum E von der Kettenrolle L aus niederbewegt wird, wie dies im Haupt-Patent beschrieben ist. Der niederbewegte Schlagbaum wird also jetzt durch seine Sperrklinke M mit der Kettenrolle gekuppelt und kann nicht schneller niederfallen, als wie die Rolle gedreht wird.In order to prevent such accidents, a pawl M is attached to the boom E , which is pulled by a counterweight M 1 behind the correspondingly extended lugs 0, FIG. several levers and the catch η the barrier boom E is moved down from the chain roller L , as described in the main patent. The barrier that has been moved down is now coupled to the chain roller by its pawl M and cannot fall down faster than when the roller is rotated.
Bevor der Schlagbaum wieder geöffnet wird, mufs bekanntlich die Kettenrolle mehrere Male in der anderen Richtung herumgeführt werden, d. h. einen Leerlauf erleiden, um später beim Schliefsen der Schranke ein Vorläuten bewirken zu können. Wäre nun in der geschlossenen Lage des Raumes der Knaggen 0 noch von der Klinke M hinterfafst, so würde der Raum E gleich beim Andrehen der Rolle wieder angehoben, also ein Leerlauf und dann später das gewünschte Vorläuten wären nicht möglich.Before the barrier is opened again, it is known that the chain roller has to be guided several times in the other direction, ie suffer an idling, in order to be able to ring the bell later when the barrier is closed. If the latch 0 were still behind by the latch M in the closed position of the room, then the room E would be raised again immediately when the roller was turned, so idling and then later the desired ringing would not be possible.
Damit dieses aber, wie im Haupt-Patent beschrieben ist, geschehen kann, erfolgt eine Ablösung der Sperrklinke M von dem Knaggen 0 dadurch, dafs kurz bevor der Baum in die Schlufslage kommt, eine Nase m} der Klinke M gegen einen Anschlag, etwa gegen den oberen Schenkel einer Winkeleisenschiene s, stöfst und dadurch die Sperrklinke von dem Knaggen 0 abgedrückt wird, Fig. 2. Die Kettenrolle ist dadurch von dem Schlagbaum wieder derart frei geworden, dafs der Leerlauf der Rolle und später das Vorläuten wie gewöhnlich geschehen können.However, so that this can happen, as described in the main patent, the pawl M is detached from the catch 0 by the fact that shortly before the tree comes into the closing position, a nose m} of the pawl M against a stop, for example against the upper leg of an angled iron rail s, and thereby the pawl is pushed off the lug 0, Fig. 2. The chain roller is thus freed from the barrier again so that the idling of the roller and later the ringing can happen as usual.
