In den Fig. 1, 2 und 3 stellt α α den Boden eines Fahrstuhles dar, welcher zwischen zwei Führungen b b in gewöhnlicher Weise geführt wird. Um ein Fallen des Fahrstuhles oder einen zu schnellen Niedergang desselben zu vermeiden, welches auch die Ursachen sein mögen, sind unterhalb des Bodens ein oder zwei Windflügel angebracht, die gewöhnlich möglichst leicht aus mit dünner Leinwand oder einem anderen Stoff, welcher der Luft Widerstand entgegensetzt, überspannten Holzrahmen d d hergestellt sind. Diese Flügel können sich um die Zapfen c c drehen. An den Rahmen sind die an ihrem unteren Ende nasenförmig umgebogenen Hebel e e befestigt. Auf der Nase dieses Hebels ruht ein scharf zugespitzter Vorsprung des Gegengewichtes ff. Dieses Gegengewicht ist an einem Doppelhebel gg befestigt, welcher um die Zapfen der Lager h h schwingen kann, die am Boden des Fahrstuhles befestigt sind. Auf der dem Gegengewichte entgegengesetzten Seite des Doppelhebels g g sind in geeigneter Gelenkvorrichtung zwei Keile ti angebracht, die in entsprechend geformten, seitlich am Fahrstuhlboden befestigten Führungsstücken geführt werden. Zwischen diesen Keilen befindet sich der senkrechte Führungsbalken bb (Holz oder Eisen). Während des regelrechten Betriebes des Fahrstuhles ist zwischen den Keilen i i und der Führung b b ein genügender Zwischenraum.In FIGS. 1, 2 and 3, α represents the floor of an elevator, which is guided between two guides bb in the usual way. In order to prevent the elevator from falling or descending too quickly, whatever the cause, one or two wind blades are attached below the floor, which are usually made of thin canvas or some other material that offers resistance to the air. spanned wooden frames dd are made. These wings can rotate around the pins cc. The levers ee, which are bent over in the form of a nose at their lower end, are attached to the frame. On the nose of this lever rests a sharply pointed projection of the counterweight ff. This counterweight is attached to a double lever gg , which can swing around the pins of the bearings hh , which are attached to the floor of the elevator. On the side of the double lever gg opposite the counterweights, two wedges ti are attached in a suitable hinge device, which are guided in correspondingly shaped guide pieces attached to the side of the elevator floor. The vertical guide beam bb (wood or iron) is located between these wedges. During the normal operation of the elevator there is sufficient space between the wedges ii and the guide bb.
Sollte der Fahrstuhl aus irgend welchem Grunde eine im Voraus festgesetzte Maximalgeschwindigkeit des Niederganges überschreiten, so heben sich die dem Luftwiderstande ausgesetzten Windflügel und lassen alsdann das mit seiner Schneide auf der Nase des Hebels e e aufruhende Gegengewicht fallen, wodurch die Keile i i gegen die Führungen b b angedrückt, d. h. geklemmt werden, was zur Folge hat, dafs entweder eine Verminderung der Geschwindigkeit des Fahrstuhles oder sein gänzlicher Stillstand bewirkt wird. Um die Wirkung des Falles der Gegengewichte zu beschleunigen , ist unter dem Boden des Fahrstuhles eine Feder in der Art angebracht, dafs dieselbe nach abwärts drückt.Should the elevator for any reason exceed a predetermined maximum speed of the companionway, the wind blades exposed to the air resistance lift and then drop the counterweight resting with its cutting edge on the nose of the lever ee , whereby the wedges ii are pressed against the guides bb , that is to say jammed, which has the consequence that either a reduction in the speed of the elevator or its complete standstill is brought about. In order to accelerate the action of the fall of the counterweights, a spring is placed under the floor of the elevator in such a way that it presses downwards.
Zur Regelung der Geschwindigkeit, bei welcher die Windflügel in Thätigkeit treten sollen, sind dieselben durch ein Gegengewicht k k theilweise ausgeglichen. Die Anwendung dieser Sicherheitsvorrichtung schliefst den Gebrauch noch anderer Sicherheitsvorrichtungen an demselben Fahrstuhle nicht aus.To regulate the speed at which the wind blades are to come into action , they are partially balanced by a counterweight kk. The use of this safety device does not preclude the use of other safety devices on the same elevator.
