Niederdruck der Tasten t die zugehörige Zählscheibe einstellt. Die lösbare Verbindung zwischen der Stange I und dem Ende des Armes des Doppelhebels"geschieht in der Weise, dass das gabelförmige Ende d des Hebels l über einen Zapfen i des Hebelarmes f'greift. Die Hebelarme t'sind durch Gelenkstangen o mit den Zahnsegmenthebeln b verbunden, die in bekannter Weise in die Verzahnung des Typensegmentes g eingreifen. Unterhalb der Stange ist ein Daumen r drehbar gelagert, dessen eines Ende sich gegen den unteren Rand der Stange l anlegt.
Das andere Ende des Daumenhebeis r steht durch die Stange q mit dem Ausrückhebel in Verbindung. Der Ein- und Ausrückhebel p sitzt auf der durchgehenden Welle z drehbar auf. Um mittels nur eines Hand-
EMI2.1
ziehen zu können, sitzen auf der Drehwelle z für jeden zugehörigen Schubstift Scheiben v auf, welche mittels eines Ausschnittes die Zapfen w der Stifte n umfassen.
Bei der in Fig. 1 dargestellten Stellung der Vorrichtung sind durch Umlegen des Handhebels p sämtliche Stifte n aus den Einkerbungen der Scheibe o herausgezogen. Gleichzeitig hat das untere Ende des als Doppelhebel ausgebildeten Handhebels 1) die Schubstange q nach rechts verschoben,

Schreibwerkes einstellt.
Bei Thomas-Rechenmaschinen, bei denen bekanntlich gleichzeitig auch multipliziert wird, tritt infolge der ausserordentlich raschen Drehung der Ziffernscheiben mittels der Kurbel die

Pressing the t buttons sets the associated counting disc. The releasable connection between the rod I and the end of the arm of the double lever "takes place in such a way that the fork-shaped end d of the lever l engages over a pin i of the lever arm f" which engage in a known manner in the toothing of the type segment G. A thumb r is rotatably mounted below the rod, one end of which rests against the lower edge of the rod l.
The other end of the thumb lifter r is connected to the release lever through the rod q. The engagement and disengagement lever p is rotatably seated on the continuous shaft z. To use just one hand
EMI2.1
To be able to pull, sit on the rotating shaft z for each associated push pin disks v, which comprise the pin w of the pins n by means of a cutout.
In the position of the device shown in Fig. 1, all pins n are pulled out of the notches in the disk o by turning the hand lever p. At the same time, the lower end of the double lever designed as a double lever 1) has moved the push rod q to the right,

Writes.
In Thomas calculating machines, which are known to also be multiplied at the same time, the extremely rapid rotation of the dials by means of the crank causes the
EMI2.3
reduced, especially since the removal of material as a result of the edge cut-outs make the digits M'lift much easier in and of themselves.
PATENT CLAIMS: 1. Total printing device for writing Thomas calculating machines, thus identified
EMI2.4
Set the type segments (g) of the writing unit according to the entry depth of the pins (n) or according to the depth of the notches in the sciieibon.
