Zwei annähernd rechtwinklig zu einander stehende Hebel α b, welche im Verhältnifs zur
Hubhöhe eine solche Länge haben, dafs mit jedem Kolbenhub nur eine Vierteldrehung erfolgt,
sind mit der Kolbenstange durch zwei Pleuelstangen c d verbunden, von denen die
kürzere c während einer Vierteldrehung nur durch Druck, die längere d während der anderen
Vierteldrehung nur durch Zug wirkt.
, Bei Fig. 1 bis 5 geschieht die Umwandlung der Vierteldrehung der Hebel α b in die umlaufende
Bewegung der Kurbel e durch einen dritten, in die Mittellinie der beiden Haupthebel
α b fallenden Hebel / und durch eine dritte Stange g. Bei Fig. 6 geschieht sie durch
einen Zahnbogen f in Verbindung mit der Zahnstange g' und Stange g. Da jedoch,
wenn die Pleuelstangen c d sowohl an der Kolbenstange als an den Hebeln α b fest angebracht
sind, eine Bewegung des Hebelwerkes unmöglich wäre, weil die Stangen
verschieden lange Wege zurücklegen müssen, so sind die Stangen so eingerichtet, dafs sie
sich entsprechend verlängern und verkürzen können, und zwar in Fig. 1 bis 6 durch Anbringung
von Büchsen cl und dl mit inliegenden
Schraubenfedern oder auch von Büchsen, in denen verdichtete Luft federnd wirkt. Die
Büchsen sind am unteren Theil jeder Stange befestigt, während der obere Theil in den
Büchsen gleitet. Bei Luftbüchsen mufs dieser Obertheil einen eingepafsten Kolben und die
Büchse von c seitlich oben, die an d seitlich unten Luftlöcher haben. Die Ausgleichung der
Länge der Stangen kann aufserdem noch auf mannigfache beliebige Art geschehen. Two levers α b, which are approximately at right angles to each other, which in relation to the stroke height have such a length that only a quarter turn occurs with each piston stroke, are connected to the piston rod by two connecting rods cd , of which the shorter c is only pressurized during a quarter turn , the longer d only acts by pulling during the other quarter turn.
In Fig. 1 to 5, the conversion of the quarter turn of the lever α b into the revolving movement of the crank e is done by a third lever falling in the center line of the two main levers α b / and by a third rod g. In Fig. 6 it happens through a toothed arch f in connection with the rack g 'and rod g. Since, however, if the connecting rods cd are firmly attached to both the piston rod and the levers α b , a movement of the lever mechanism would be impossible because the rods have to cover distances of different lengths, the rods are arranged in such a way that they lengthen accordingly and Can shorten, namely in Fig. 1 to 6 by attaching sleeves c l and d l with internal coil springs or sleeves in which compressed air acts resiliently. The rifles are attached to the lower part of each rod, while the upper part slides in the rifles. In the case of air cans, this upper part must have a fitted piston and the can from c on the top side, which on d laterally have air holes on the bottom. The length of the rods can also be adjusted in any number of ways.
So kann der erforderliche Spielraum auch an die Kolbenstange verlegt werden, z. B. durch zwei Kolben und deren zwei in einander liegende Stangen, also für jede Pleuelstange c d durch einen eigenen Kolben und eine eigene Kolbenstange.So the required clearance can also be relocated to the piston rod, e.g. B. by two pistons and their two mutually lying rods, so for each connecting rod cd by its own piston and piston rod.
Die Erfindung bietet nach Angabe des Erfinders hauptsächlich den Vortheil, dafs eine während der Arbeitsleistung abnehmende Kraft eine unveränderliche Wirkung auszuüben vermag, sie ist daher nicht blos für Dampfmaschinen, sondern überall da verwendbar, wo eine sich mindernde Kraft unveränderliche Wirkung oder umgekehrt eine unveränderliche Kraft eine veränderliche Wirkung hervorbringen soll.According to the inventor, the invention offers the main advantage that one decreasing force during work is able to exert an invariable effect, It is therefore not just for steam engines, but can be used wherever one diminishing force an unchanging effect or, conversely, an unchanging force should produce a changeable effect.
