Nach der Erfindung wird die Energie des Elektromotors in zwei Federtrommeln aufgespeichert, von denen die eine die Typen einstellt, während die andere das Drucken und die damit zusammenhängenden anderen Operationen bewirkt. In dieser AusführungsartThe subject of the invention is the drive of a receiver apparatus for electrical Typewriter systems by means of a -local power source fed, temporarily running electric motor, whose energy is stored in spring drums and from these is passed on to the organs of the apparatus to be moved. According to the invention the energy of the electric motor is stored in two spring drums, one of which is the Types, while the other sets printing and the other related Operations effected. In this version

.■ eignet sich die Einrichtung für einen Apparat mit einer Elektromagneteinrichtung, die zwei verschiedene Anker besitzt, von denen der eine bei schnell aufeinanderfolgenden Stromimpulsen diesen entsprechend schwingt, während der andere sich nur bei längeren Stromunterbrechungen bewegt. Jeder dieser Anker regelt dann die Bewegung einer der beiden Federtrommeln.. ■ the device is suitable for an apparatus with one solenoid device, the two has different armatures, one of which in the case of rapidly successive current pulses this oscillates accordingly, while the other only moves in the event of longer power interruptions emotional. Each of these anchors then regulates the movement of one of the two spring drums.

Auf der Zeichnung ist eine Einrichtung der angegebenen Art in Fig. ι bis 5 dargestellt. In die Zeichnung sind nur die unmittelbar mit dem Antrieb zusammenhängenden Teile des Empfängerapparates mit aufgenommen.In the drawing, a device of the type indicated in Fig. Ι to 5 is shown. In the drawings are only those parts of the receiver that are directly related to the drive recorded with.

Der nicht dargestellte Elektromotor ist mit der Welle 130 gekuppelt, deren Drehung vermittels des ^Schneckengetriebes 131, 132 auf die Welle 133 übertragen wird. Auf letzterer sitzt die Federtrommel 134, die dazu dient, die Ener-■ gie des Motors zeitweilig aufzuspeichern und an die zum Drucken und den damit zusammenhängenden Operationen dienenden Mechanismen weiterzugeben. Außerdem sitzt auf der Welle 133 das Zahnrad 135, welches das auf der Achse 137 sitzende Zahnrad 138 durch das Zwischenrad 136 antreibt. Auf der Achse 137 sitzt die Federtrommel 139, in welcher die Kraft zur Fortschaltung des Typenrades aufgespeichert wird. Die Weitergabe der Kraft von der Federtrommel erfolgt vermittels des Triebes 27 auf das Schaltrad 29 und von diesem vermittels der Klinke 5 auf die Achse 3 des Typenrades. Die erwähnten Zahntriebe sind zum größten Teil an der Platte 140 gelagert. Von der Federtrommel 134 wird der Trieb 142 gedreht, der auf der Welle 141 sitzt. Diese trägt außerdem ein Daumenrad 143, welches auf die an einem Hebel 145 vorgesehene Rolle 144 einwirkt. Ein am Ende der Welle 141 befestigtes Zahnrad 141¹ dreht unter Vermittlung eines nicht dargestellten Zwischengetriebes einen auf der Achse 146 sitzenden Trieb 147, an welchem sich ein doppelarmiger Hebel 148 befindet. In der Bahn des letzteren liegt ein Auslösehebel 149, der mittels des Armes 150 mit dem Anker 40 des Elektromagneten 39 verbunden ist, der durch die vom Sender her anlangenden Stromimpulse erregt wird. Der Anker 40 ist so eingerichtet, daß er bei Beginn der Stromimpulse angezogen, aber nur bei deren Unterbrechung wieder freigegeben wird, während ein zweiter Anker 36, der die Fortschaltung des Typenrades regelt, den Stromimpulsen entsprechend schwingt. Beim Anziehen des Ankers 40 verläßt der Hebel 148 mit seinem winkelförmigen Ende die obere Auflagefläche des Hebels 149 und legt sich auf einenThe electric motor, not shown, is coupled to the shaft 130, the rotation of which is transmitted to the shaft 133 by means of the worm gear 131, 132. The spring drum 134 sits on the latter and serves to temporarily store the energy of the motor and to pass it on to the mechanisms used for printing and the associated operations. In addition, the gear 135 is seated on the shaft 133 and drives the gear 138, which is seated on the axle 137, through the intermediate gear 136. On the axle 137 sits the spring drum 139, in which the force for advancing the type wheel is stored. The transmission of the force from the spring drum takes place by means of the drive 27 to the ratchet wheel 29 and from this by means of the pawl 5 to the axis 3 of the type wheel. Most of the gear drives mentioned are mounted on the plate 140. The drive 142, which sits on the shaft 141, is rotated by the spring drum 134. This also carries a thumb wheel 143, which acts on the roller 144 provided on a lever 145. ^{A gear wheel 141 1} fastened to the end of the shaft 141 rotates a drive 147 which is seated on the axle 146 and on which a double-armed lever 148 is located, through the intermediary of an intermediate gear (not shown). In the path of the latter there is a release lever 149 which is connected by means of the arm 150 to the armature 40 of the electromagnet 39, which is excited by the current pulses arriving from the transmitter. The armature 40 is set up in such a way that it is attracted at the beginning of the current pulses, but is only released again when they are interrupted, while a second armature 36, which controls the advance of the type wheel, oscillates according to the current pulses. When the armature 40 is tightened, the lever 148 leaves the upper bearing surface of the lever 149 with its angled end and rests on one

lower sales of the same lever. If the armature 40 then falls back into its rest position, so the lever also slides from the lower shoulder through a recess and completes one turn by not stopping until it hits the top Contact surface of the lever 149 meets.

It is expedient to make the known device that the electric motor only needs to work from time to time when the spring drums have given up part of their power, and is switched off again when the necessary force is stored again in the spring drums. The motor is switched on and off automatically by the movement of the spring drum 134 or by the movement of the shaft 133 resilient member 155 presses against an end disk of the sleeve 154, which rests on a fixed ring 156 on the other side. ^{A tooth 154 1} is seated on this sleeve 154 and engages in rack teeth 154 ^{2 of} the switching arm 158, which is rotatably arranged on the isolated axis 159. So that a rotation by the dead weight of the arm 158 cannot occur, a resistor is expediently arranged on the axis 159, e.g. B. by resilient engagement of elevations of a disk connected to the arm in an opposite disk of the axle 159. The arm 158 also has a second rack toothing on the other side

153 ² . A tooth 153 ^{1 of} a sleeve 153, which likewise sits loosely on the shaft 133 and is provided with an inclined slot 152 ¹ , can engage in this. In this slot engages a seated on the shaft 133 pin 152, while springs 151 are trying to push the sleeve to the left, so that the tooth 153 ^{1 is} out of engagement with the toothing 153 ² , and also by engagement of the Spring-attached elevations 151 ^x in tooth-gap-like depressions 151 ^{2 of} the end disk of the sleeve to cause a resistance to rotation of the sleeve. In addition to the switching lever 158 with the hook-shaped end 158 ^1, the spring lever 161 is mounted in the bearing block 157 so as to be rotatable and insulated from its axis 160. At its end there is the pawl-like holder 162 which is pressed down by the spring 163. In the rest position, the spring lever is pressed against the stop pin 165 by the helical spring 164 and is provided with a contact spring 166. The levers 161 and 158 are connected to the power source and the motor by wires. The operation of the device described is as follows:

When the spring drum 134 rotates, in the sense of the arrow drawn in FIG. 3, the sleeve 154 is taken along and consequently rotates ^{the switching arm 158 by means of the tooth 154 1} towards the spring lever 161 while the shaft 133 stands still. When the arm 158 has reached the spring lever 161, the power is closed and the motor begins to operate. As a result, the shaft rotates

133 in the same sense as the drum before

134 and presses the sleeve 153 to the right by means of the pin 152, so that the tooth 153 ¹ engages the toothing 153 ² and moves the switching arm 158 to the right, taking the spring lever 161 with it a little until the hook 158 ¹ jumps off the holder 162 and thus a spark-free switch-off of the current occurs. As a result, the motor stops running, the shaft 133 stops, and the sleeve 153 is withdrawn with a helical rotation by the springs 151, the protrusions 151 * of which are not in the rotation-inhibiting depressions 151 ^{2 in this position, so that the} Tooth 153 ¹ emerges from the toothing 153 ² and so the new forward movement of the switching arm 158 can begin again with further rotation of the drum .134.

Instead of the arrangement described, any other device can also be used, by the mutual rotation between drum shaft and drum when reached the motor is switched on and off at a certain angle.
