EMI1.1
Der Gegenstand der Erfindung bezieht sich auf eine Vorrichtung zum Ziehen von Summen und Zwischensummen für Rechenmaschinen, die zwecks Addition und Subtraktion mit einem umschaltbaren Zählwerk ausgerüstet sind, und bezweckt, eine selbsttätige Sicherung zwischen der Stellung des Summenhebels und der des Umstellhebels für dae umschaltbare Zählwerk zu schaffen.
Zu diesem Zwecke ist gemäss der Erfindung zwischen dem Summenhebel und Umstellbebel für das umschaltbare Zählwerk eine derartige Verbindung vorgesehen, dass der Summenhebel, wenn er zwecks Bildung einer Summe oder Zwischensumme umgelegt wird, selbsttätig den UmsteM- hebel für das umschaltbare Zählwerk in die Additionsstellung einstellt, wenn dieser zuvor auf Subtraktionsstellung gestanden hat, und ferner gleichzeitig auch eine Sperrvorrichtung zur Wirkung bringt, die bei umgelegtem gumnienhebel eine Bewegung des Umstellhebels verhindert.
Das Einstellen des Umstellhebels in die Additionsstellung durch Umlegen des Summenhebels kann nun entweder unmittelbar durch die Umlegung des Summenhebels erfolgen oder auch dadurch, dass beim Umlegen des Summenhebels ein Zwischenglied verstellt wird, so dass bei dem darauffolgenden Kurbelzug die Einstellung des Umstellhebels durch die Handkurbel bzw. die Antriebsvorrichtung der Rechenmaschine unter Vermittlung des erwähnten Zwischengliedes erfolgt.

dass durch den Summenhebel nur ein Zwischenglied verstellt wird und Fig. 5 Mine der Fig. t entsprechende Ansicht in anderer Arbeitsstellung.
Der Summenhebel bzw. Zwischensummenhebel 6 Ist in bekannter Weise schwingbar auf einer Welle 11 angeordnet, die ferner emen Hebel 7 trägt. Dieser hebel 7 ist mit einem Schlitz 7a

den Umstellhebel 1 mit Gewalt umzulegen. so könnte durch die grosse Hebel@bersetzung die Welle 8 zu stark auf Verdrehung beansprucht werden, aus welchem Grunde zweckmässig zur Entlastung der Welle 8 noch eine besondere Sperrvorrichtung vorzusehen ist. Zu dresem Zwecke ist eine Klinke 3 schwingbar im Seitenrahmen der Rechenmaschine gelagert und besitzt einen nach oben reichenden Arm Ja, der mit Hilfe der Feder, 3b in der Xormalstellung des Summenhebels gegen den Anschlagzapfen 9 auf dem Arm 4 gezogen wird.

EMI1.1
The object of the invention relates to a device for pulling sums and subtotals for calculating machines, which are equipped with a switchable counter for addition and subtraction, and aims to provide an automatic backup between the position of the totaling lever and that of the switching lever for the switchable counter create.
For this purpose, according to the invention, a connection is provided between the sum lever and changeover lever for the switchable counter, so that the sum lever, when it is turned over for the purpose of forming a total or subtotal, automatically sets the changeover lever for the switchable counter into the addition position, if this was previously in the subtraction position, and at the same time also brings a locking device into effect, which prevents movement of the switch lever when the rubber lever is turned.
The setting of the changeover lever into the addition position by moving the sum lever can now be done either directly by moving the sum lever or by adjusting an intermediate link when the sum lever is turned over, so that the setting of the change lever can be done with the crank handle or the crank handle in the subsequent crank pull. the drive device of the calculating machine takes place with the intermediary of the mentioned intermediate member.

that only one intermediate link is adjusted by the sum lever and FIG. 5 mine of FIG. t corresponding view in a different working position.
The sum lever or subtotal lever 6 is arranged in a known manner on a shaft 11, which also carries a lever 7 so that it can swing. This lever 7 has a slot 7a
EMI1.3
to throw the switch lever 1 with force. so the shaft 8 could be subjected to excessive torsional stress due to the large lever ratio, for which reason it is advisable to provide a special locking device to relieve the shaft 8. For this purpose, a pawl 3 is pivotably mounted in the side frame of the calculating machine and has an upward-reaching arm Ja, which is pulled against the stop pin 9 on the arm 4 with the aid of the spring 3b in the normal position of the sum lever.
The latch 3 also has
