Patentiert im Deutschen Reiche vom 16. Februar 1908 ab. Längste Dauer: 29. Oktober 1922.Patented in the German Empire on February 16, 1908. Longest duration: October 29, 1922.
Dem Hauptpatent liegt die Einrichtung zugrunde, daß ein Schwinghebel quer unter den Tasten hinwegführt und beim Arbeitsgang mit dem Schaltwerk gekuppelt wird, um entsprechend der jeweils niedergedrückten Taste eine begrenzte. Bewegung des Schaltwerkes zuzulassen. Die schwingende Bewegung des Hebels nach der einen Richtung (Arbeitsgang, Gang in gekuppeltem Zustande) wurde dazu nutzbar gemacht, die Entriegelung der jeweils niedergedrückten Taste herbeizuführen. The main patent is based on the device that a rocker arm transversely under the Keys leads away and when working with the rear derailleur is coupled to accordingly of the key depressed. To allow movement of the rear derailleur. The swinging movement of the lever in one direction (working gear, gear in coupled state) could be used for this purpose made to bring about the unlocking of the respectively depressed key.
Die neue Erfindung bezieht sich nun darauf, diesen Schwinghebel zur Entriegelung solcher Sicherheitsvorrichtungen nutzbar zu machen, durch welche alle übrigen, nicht niedergedrückten Tasten gegen ein Niederdrücken gesichert werden, während sich die angeschlagene Taste im. niedergedrückten Zustande befindet. Vorteilhaft wird die zweite Schwingperiode, der Leer- oder Rückgang des Schwinghebels, hierzu benutzt, und die Verriegelungsvorrichtung ist derart konstruiert, daß außer der Sicherung gemäß dem Hauptpatent auch die jeweils niedergedrückte Taste noch eine Sicherung erfährt, die darin besteht, daß unmittelbar nach dem Emporschnellen der Taste ein nochmaliges schnelles Herunterdrücken, bevor der Schwinghebel in seine Anfangslage gelangt ist, verhindert wird.The new invention now relates to this rocker arm for unlocking such To make safety devices usable, through which all the rest, not depressed Keys are secured against being depressed while the pressed key is in the. depressed state. The second oscillation period, the empty or return of the rocker arm, used for this purpose, and the locking device is constructed in such a way that in addition to the fuse according to the main patent, each pressed key still experiences a backup, which consists in that immediately after When the button goes up, press it down again quickly before the rocker arm has reached its initial position is prevented.
Auf der Zeichnung sind zwei Ausführungsformen der Erfindung dargestellt, und zwar ebenso wie beim Hauptpatent, für den Fall, daß ein motorischer Antrieb für das Schaltwerk vorhanden ist.In the drawing, two embodiments of the invention are shown, namely as with the main patent, in the event that a motor drive for the switching mechanism is available.
Fig. ι zeigt einen Querschnitt durch die Maschine mit dem Anblick auf einen Tastenhebel, wobei die Taste sich in ihrer normalen Stellung befindet. Fig. 2 zeigt die Taste in ihrer untersten Stellung, und Fig. 3 zeigt eine weitere Ausführungsform der Erfindung mit der Taste in ihrer oberen Stellung.Fig. Ι shows a cross section through the machine with the sight of a key lever with the key in its normal position is located. Fig. 2 shows the key in its lowest position, and Fig. 3 shows a further embodiment of the invention with the button in its upper position.
Die wesentlichen Teile weisen gleiche Zahlenbezeichnung mit der Hauptpatentschrift auf. 41 ist die Taste und 10 ist der von der Schaltwerksachse ι durch Vermittlung von Zahnrädern angetriebene, hin und her schwingende und sich unter allen Tasten entlang erstreckende Hebel.The essential parts have the same numerical designation as the main patent specification. 41 is the button 10, the of the switching mechanism axis ι through the intermediary of gears driven back and forth swinging and under all keys extending along lever.
In den Fig. 1 und 2 ist die neue Sperrvorrichtung folgendermaßen ausgebildet: Auf einer schwingbaren Welle 50 sitzt eine der Anzahl der Tastenhebel 41 entsprechende Zahl von Hebeln 51, welche durch Federspannung das Bestreben haben, ständig nach links gedrückt zu werden. Liegt der Schwinghebel 10 in seiner in Fig. ι gezeichneten Null- oder Anfangslage, so überwindet sein Federdruck den Federdruck der Hebel 51, und er hält die Hebel in der LageIn Figs. 1 and 2, the new locking device is designed as follows: On one oscillating shaft 50 is seated a number of the number of key levers 41 corresponding to Levers 51, which strive by spring tension, are constantly pressed to the left to become. If the rocker arm 10 is in its zero or initial position shown in FIG. so its spring pressure overcomes the spring pressure of the levers 51, and it keeps the levers in position
