KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. KLASSE 47: Maschinenelemente.CLASS 47: Machine elements. Die Pleuelstange einer liegenden Kraftmaschine greift mit ihrem Lager α an der zum doppelarmigen Hebel gestalteten Kolbenstange b an, welche ihren Dreh- und Stützpunkt im Kreuzkopf bei c findet, und bewirkt durch den in ihrer Achse nach unten wirkenden Druck die Entlastung des Kolbens von seinem Eigengewicht.The connecting rod of a horizontal engine engages with its bearing α on the double-armed lever designed piston rod b , which finds its pivot and support point in the cross head at c , and causes the piston to relieve its own weight through the pressure acting down its axis . Der Abstand des Zapfens α vom Drehpunkt c wird unter Berücksichtigung des mittleren Kolbendruckes bestimmt und ermöglicht es, das Gewicht des Kolbens nahezu vollständig auszugleichen und so das Aufliegen des Kolbens auf der unteren Cylinderwandung, namentlich während des mittleren Kolbenlaufes, wo die gröfste Durchbiegung der Kolbenstange stattfindet, zu vermeiden.The distance of the pin α from the pivot point c is determined taking into account the mean piston pressure and makes it possible to almost completely compensate for the weight of the piston and thus for the piston to rest on the lower cylinder wall, namely during the middle piston stroke, where the greatest deflection of the piston rod takes place , to avoid. Patenτ-Ansρruch:Patenτ claim: Ein Schubkurbelgetriebe für liegende Kraftmaschinen, bei welchem die bei c im Kreuzkopf drehbare und jenseits des Kreuzkopfes bei α an die Pleuelstange angeschlossene Kolbenstange b einen doppelarmigen Hebel bildet, so dafs der in der Richtung der Pleuelstange auftretende Druck oder Zug das Gelenk α stets nach unten drückt oder zieht und somit den Kolben von der unteren Cylinderwandung abhebt.A slider crank mechanism for horizontal engines, in which the piston rod b, rotatable in the cross head at c and connected to the connecting rod at α on the other side of the cross head, forms a double-armed lever, so that the pressure or tension occurring in the direction of the connecting rod always pushes the joint α downwards or pulls and thus lifts the piston off the lower cylinder wall.
