Patentirt im Deutschen Reiche vom 16. Januar 1885 ab.Patented in the German Empire on January 16, 1885.

In den Zeichnungen sind in Fig. 1 und 2 zwei Constructionen einer Prefsvorrichtung angegeben, durch welche der Prefsbalken auf beiden Seiten gleichmäfsig belastet wird.In the drawings, two constructions of a pressing device are indicated in FIGS. 1 and 2, by which the pref beam is evenly loaded on both sides.

In Fig. ι wirkt der mit dem Fufstritt T versehene Winkelhebel Tb1 αλ C1 bei C1 auf die linke Zugstange Z1, der mittelst der Zugstange G verbundene Winkelhebel b2 a2 C2 wirkt bei C2 auf die Zugstange Z2. Die bei T eingeleitete Kraft wird also auf beide Enden des Prefsbalkens P genau gleichmäfsig übertragen.In Fig. Ι provided with the Fufstritt T angle lever acts Tb 1 α λ C 1 at C 1 to the left tie rod Z 1, which by means of the draw bar G associated angle lever b 2 a 2 C 2 operates at C 2 on the drawbar Z 2 . The force introduced at T is thus transmitted exactly evenly to both ends of the pref beam P.

In Fig. 2 bewirkt dieses Abwärtsbewegen des Prefsbalkens P der mit dem Fufstritt T versehene Hebel Tb1 αλ C1 in Gemeinschaft mit dem durch Zugstange G verbundenen Hebel b2 a% C2, welche beide mittelst der Zugstangen S1 S2 an dem Querträger Q. angreifen. Das Aufwärtsbewegen des Prefsbalkens P geschieht bei beiden Constructionen durch die Federn F1 F2.In Fig. 2, this downward movement of the Prefsbalkens P provided with the footstep T lever Tb 1 α λ C 1 in common with the lever B 2 a % C 2 connected by pull rod G, which both by means of the pull rods S 1 S 2 on the Attack cross member Q. The upward movement of the prefab beam P occurs in both constructions by the springs F 1 F 2 .

Claims (1)

PateNT-AnsPRυCH:PateNT CLAIM: Zur Erreichung eines auf beiden Seiten genau gleichmäfsigen Druckes des Prefsbalkens P die mittelst der Stangen S1 S2 am Quersteg Q., wie Fig. 2, bezw. direct an den Zugstangen Z1 2T2, wie Fig. 1, angreifenden beiden Hebel Tb1 U1 C1 und b2 a2 C2, verbunden durch die Zugstange G.To achieve a pressure of the Prefsbalkens P which is exactly the same on both sides, the means of the rods S 1 S 2 on the crossbar Q., as in FIG. 2, respectively. The two levers Tb 1 U 1 C 1 and b 2 a 2 C 2 that act directly on the tie rods Z 1 2T 2 , as in FIG. 1, are connected by the tie rod G.
