Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Den Gegenstand der Erfindung bildet ein Sperrhebel zum Anziehen von Bremsen, bei
dem die Sperrung durch seitliches Ausschwingen des Hebels gelöst wird.
Von den bekannten Hebeln dieser Art unterscheidet sich der Erfindungsgegenstand durch die besondere Ausbildung der Zähne
des Sperrkranzes, durch die der Hebel sicher in seiner Sperrlage gehalten wird,
ίο Auf der Zeichnung ist der Erfindungsgegenstand dargestellt, und zwar zeigt:
Fig. ι eine Draufsicht des Sperrhebels,
Fig. 2 eine Seitenansicht zu Fig. i,
Fig. 3 eine Seitenansicht mit seitlich geschwungenem
Hebel,The subject of the invention is a locking lever for applying brakes, in which the locking is released by swinging the lever sideways.
The subject of the invention differs from the known levers of this type in the special design of the teeth of the locking ring, by means of which the lever is securely held in its locking position,
ίο The subject of the invention is shown in the drawing, namely shows:
Fig. Ι a plan view of the locking lever,
FIG. 2 is a side view of FIG.
3 shows a side view with a laterally curved lever,
Fig. 4 einen Schnitt nach der Linie r-v der Fig. 1.FIG. 4 shows a section along the line rv in FIG. 1.
Der Sperrhebel α ist durch einen Bolzen, der gleichzeitig noch eine Platte g hält, mit dem Sperrkranz b, der am Wagengestell o. dgl. befestigt wird, verbunden. In den Sperrkranz greift die durch eine Feder d vorgedrückte Sperrklinke e und sichert so den Hebel in seiner Lage. Das untere Ende des Hebels besteht aus zwei ineinanderliegenden, durch ein seitliches Gelenk c miteinander verbundenen Teilen. Durch diese Anordnung ist es ermöglicht, den Hebel seitlich zu schwingen, dadurch die Sperrklinke außer Eingriff mit den Zähnen zu bringen und nun den Hebel zurückzuschwingen. Ein über die Platte g greifender Anschlag h begrenzt die Seitswärtsschwingung des Hebels, während eine Feder f den Hebel in seine Sperrlage zurückzubringen sucht. Die Zähne des Sperrkranzes steigen nun gemäß der Erfindung nach der Seite, nach welcher der Hebel seitlich ausgeschwungen wird, an (Fig. 2 und 3), wodurch ein sicheres Halten des Hebels in der Sperrlage gewährleistet werden soll.The locking lever α is connected by a bolt, which at the same time also holds a plate g , to the locking ring b, which is attached to the carriage frame or the like. The locking pawl e , which is pushed forward by a spring d, engages in the locking ring and thus secures the lever in its position. The lower end of the lever consists of two nested parts connected to one another by a lateral hinge c. This arrangement makes it possible to swing the lever sideways, thereby disengaging the pawl from the teeth and now swinging the lever back. A stop h reaching over the plate g limits the sideways oscillation of the lever, while a spring f tries to bring the lever back into its blocking position. According to the invention, the teeth of the locking ring rise to the side towards which the lever is swung out to the side (FIGS. 2 and 3), which is intended to ensure that the lever is held securely in the locked position.
