gelochter Streifen.perforated strip.

Patentiert im Deutschen Reiche vom 30. Juni 1908 ab. Patented in the German Empire on June 30, 1908.

Die Erfindung betrifft eine Vorrichtung zum selbsttätigen Betriebe einer oder mehrerer Schreibmaschinen, deren Antrieb mittels je eines gelochten Streifens und elektrischer Übertragung erfolgt. Von den bekannten Vorrichtungen dieser Art, bei welchen der gelochte Streifen über eine Kontaktvorrichtung geführt wird, unterscheidet sich der Erfindungsgegen-■■-^y stand dadurch, daß die Bewegung der auf ίο .dem gelochten Streifen laufenden Kontaktwalze durch Elektromagnete ein- und ausgerückt wird, die in Stromkreise eingeschaltet sind, welche durch besondere Schalter oder mittels über den gelochten Streifen gleitender Kontaktfinger geschlossen werden. Zur Verschiebung des Papierschlittens mittels durch Luft bewegter Kolben werden die Kolbengehäuse mit Hilfe von Elektromagneten und Ventilen mit einem luftverdünnten Raum in Verbindung gebracht.The invention relates to a device for the automatic operation of one or more typewriters, the drive of which is carried out by means of a perforated strip and electrical transmission. Of the known devices of this kind, in which the perforated strip guided over a contact device, is matter of the invention differs ■■ - ^y stand characterized in that the movement of the running on ίο .dem perforated strip contact roll off by electromagnets and is disengaged, which are switched on in circuits which are closed by special switches or by means of contact fingers sliding over the perforated strip. To move the paper carriage by means of pistons moved by air, the piston housings are brought into contact with an air-diluted space with the aid of electromagnets and valves.

Die mit dem durchlochten Streifen O zusammenwirkende Kontaktwalze M und die Kontaktfinger N werden zum Betrieb der Tastenhebel L einer oder mehrerer Schreibmaschinen A, B, C in bekannter Weise benutzt unter Verwendung von Solenoiden /, die in die elektrischen Stromkreise H eingeschaltet und deren Kerne durch Drähte K mit den Tastenhebeln L verbunden sind. Federn R führen die Kerne / in die Ruhelage zurück. Die Kontaktwalze M dient zweckmäßig als Zuführungswalze für den durchlochten Streifen O und wird vermittels eines Riemens T bewegt, der über Fest- und Losscheiben U und V geführt ist. Der Riemen T wird, um die Kontaktwalze M in Gang zu setzen oder still zu setzen, vermittels eines dreiarmigen Hebels W und einer mit einer Riemengabel Y versehenen Schubstange X durch ein Paar von Solenoiden Z und α ein- bzw. ausgerückt. Der das Solenoid Z durchfließende Stromkreis wird vermittels eines Schalters b geschlossen, und der das Solenoid α durchfließende Stromkreis, welcher den Riemen T auf die Leerlaufscheibe V ausrückt, wird vermittels eines Kontaktfingers c geschlossen, so daß das Anhalten der Kontaktwalze M selbsttätig erfolgt, sobald die 'Arbeit beendigt ist.The contact roller M cooperating with the perforated strip O and the contact fingers N are used to operate the key levers L of one or more typewriters A, B, C in a known manner using solenoids / which are connected to the electrical circuits H and their cores by wires K are connected to the key levers L. Springs R return the cores / to the rest position. The contact roller M expediently serves as a feed roller for the perforated strip O and is moved by means of a belt T which is guided over fixed and loose pulleys U and V. The belt T is engaged or disengaged through a pair of solenoids Z and α by means of a three-armed lever W and a push rod X provided with a belt fork Y in order to start or stop the contact roller M. The circuit flowing through the solenoid Z is closed by means of a switch b , and the circuit flowing through the solenoid α , which disengages the belt T on the idler pulley V , is closed by means of a contact finger c , so that the contact roller M stops automatically as soon as the 'Work is finished.

Die Kontaktfinger N sind in Schlitzen g eines Halters f aus einem gut isolierenden Material, wie z. B. Vulkanit oder Holz, gelagert, und Stifte e auf jeder Seite des Halters f dienen dazu, die Kontaktfinger N an ihrem Platze zu halten, ohne ihre freie Bewegung zu beeinträchtigen. Die Führungsschlitze g trennen die Kontaktfinger N von-The contact fingers N are in slots g of a holder f made of a good insulating material, such as. B. vulcanite or wood, stored, and pins e on each side of the holder f are used to hold the contact fingers N in place without affecting their free movement. The guide slots g separate the contact fingers N from

each other and prevent them from coming into contact with one another. The ends of the contact fingers N are beveled so that they can slide easily over the perforated strip 0. A pressure roller i causes the perforated strip to move smoothly over the contact roller M, and a pair of tensioning rollers j and k, one of which has lateral flanges I, serve to guide the ίο perforated strip. The carriage m of the typewriter is guided back by means of a line separating lever m 'through a piston ft which is moved by means of suction and which is known per se and is connected to the lever m' by a cord η and which is arranged in a cylinder q. The piston ft is drawn into the cylinder q as soon as the das. Solenoid s flowing circuit r 'is closed. The core s' of the solenoid s moves the valve lever t of a valve switched on in the suction line u going out from a vacuum container Y. When the paper carriage m is in its outer limit position, contacts w, w 'come into contact with one another and close the circuit to the solenoid y, whose core y' moves the arm ζ of the valve lever. As a result, the cylinder q is shut off from the vacuum line and brought into contact with the outside atmosphere. As a result, since the piston ft is pulled out of the cylinder q by a spring s ", the paper carriage can follow the influence of the usual switching mechanism of the typewriter. The position of the valve in which it is connected to the vacuum container Y is shown in FIG , and in Fig. 4 the position is shown in which it connects the cylinder q to the outside atmosphere for triggering the piston ft. The device shown schematically in Figs. 1 and 2 comprises an alternator A ', a transformer B' for the same and inductive resistors C in the main circuits. D ', D' denote switches for connecting the typewriter circuits to the main circuit; these switches can be placed in any desired position. It is not necessary that the typewriters close together or with the perforated strips and the contact fingers are arranged; the perforated strips can be at any distance ng from the typewriters, for example in another room. The embodiment shown can be changed in terms of structural design and arrangement without deviating from the basic concept of the invention. The advantage of using alternating current is that the contacts can be made without sparking. Godfather ν T-A ν Proverbs:
