Patentirt im Deutschen Reiche vom l. October 1884 ab.Patented in the German Empire from l. October 1884.
Die Erfindung bezweckt eine Vereinfachung des Nachspannens der Spann- oder Dichtungsringe bei Kolben.The invention aims to simplify the retensioning of the clamping or sealing rings with pistons.
Bisher war man genöthigt, beim Nachstellen der Spannringe den Cylinderdeckel abzunehmen und den Kolben zu offnen, um das Spannen bewirken zu können. Bei der vorliegenden Einrichtung können die Spannringe nach Entfernen von in den Cylinderdeckel eingeschraubten Verschlufspfropfen durch Stellschrauben mittelst eines durch die Pfropfenbohrungen eingebrachten Schraubenschlüssels genau gestellt werden, worauf man den Cylinder durch Einschrauben der Pfropfen wieder schliefst.Up to now it was necessary to remove the cylinder cover when readjusting the clamping rings and to open the piston in order to be able to effect the cocking. With the present Device, the clamping rings can be screwed into the cylinder cover after removing Closure plug by adjusting screws by means of one through the plug holes introduced wrench must be placed exactly where you want the cylinder by screwing the stopper back asleep.
Die Fig. 1 und 2 zeigen in der Nabe a des auf der Kolbenstange b aufgekeilten Kolbens c mehrere eingeschraubte oder anderweitig befestigte gabelartige Theile d, welche durch Kniehebel e e mit den Gelenken f der Spannfedern g verbunden sind. Die auf die Nabe a aufgeschobene Platte h liegt auf den Kniehebeln. Werden nun die in den Kolbendeckel eingeschraubten Nachstellschrauben i angezogen, so drücken sie die Platte h abwärts, bewirken ein Strecken der Kniehebel und dadurch ein Auswärtsdrängen der Federn g in radialer Richtung. Diese Federn g, welche sich an den Spannring k ringsum anlegen, verursachen auf diese Art das Nachspannen.Figs. 1 and 2 show in the hub of a b on the piston rod keyed piston c multiple screwed or otherwise fixed fork-like part d, which ee by toggle with the joints f of the tension springs are connected g. The plate h pushed onto the hub a lies on the toggle levers. If the adjusting screws i screwed into the piston cover are now tightened, they press the plate h downwards, cause the toggle levers to stretch and thereby push the springs g outward in the radial direction. These springs g, which are applied all around the clamping ring k , cause the retensioning in this way.
Die Schrauben i sind so lang, dafs sie in der Todtlage des Kolbens in die Höhlungen der in den Cylinderdeckel / eingeschraubten Pfropfen m reichen. Um den Spannring nachzustellen, stellt man die Maschine in den todten Punkt, entfernt die Pfropfen m und spannt die Federn durch Drehen der nun bei den Pfropfenbohrungen herausstehenden Schrä'ubchen i mittelst eines Schraubenschlüssels nach, worauf man die Pfropfen nt wieder einschraubt.The screws i are so long that, when the piston is dead, they reach into the cavities of the plugs m screwed into the cylinder cover. In order to readjust the tension ring, the machine is set to the dead point, the stopper m is removed and the springs are tightened by turning the screws i now protruding from the stopper bores using a wrench, after which the stopper nt is screwed in again.
Fig. 3 und 4 zeigen einen Kolben, welcher nur ein einziges derartiges Nachstellgetriebe besitzt. Hier drückt das Schräubchen i unmittelbar auf den Kniehebel ee, und das Gelenk j> trägt keine Feder, sondern um den Bolzen fl drehbar zwei steife Streben gt, welche sich gegen die Ansätze j des Spannringes k stützen. Das Nachstellen der Schraube i bewirkt durch Strecken des Kniehebels e e ein Vorschieben des Theiles / und Bolzens f\ Fig. 4; infolge dessen öffnet sich der durch die Streben g1 gebildete Winkel, wodurch die Ansätze j und mit ihnen der Spannring dicht an die Cylinderwand. geprefst werden.3 and 4 show a piston which has only a single such adjusting gear. Here the screw i presses directly on the toggle lever ee, and the joint j> does not carry a spring, but rather two rigid struts g t , rotatable around the bolt f l , which are supported against the shoulders j of the clamping ring k . The readjustment of the screw i causes the part / and bolt f \ Fig. 4 to be advanced by stretching the toggle lever ee; as a result, the angle formed by the struts g 1 opens, whereby the lugs j and with them the clamping ring close to the cylinder wall. be pressed.
Man kann auch den Kniehebel so anordnen, dafs sein Scheitel nicht gegen den Cylinderdeckel Z, sondern entgegengesetzt gerichtet ist. In diesem Falle müssen die Nachstellschrauben i mit dem Kniehebel verbunden sein, da dessen Strecken dann nicht durch einen auf denselben wirkenden Druck, sondern durch Zug bewerkstelligt werden mufs.The toggle lever can also be arranged in such a way that its apex is not directed towards the cylinder cover Z, but in the opposite direction. In this case, the adjustment screws i must be connected to the toggle lever, since its stretching then does not have to be accomplished by a pressure acting on it, but rather by pulling it.
