CLASS 21 α

The purpose of the present invention is to provide two with the push of a button or several typewriters, calculating machines, pianos set up separately and the like to put into action by electrical means and in this way a and the same document or piece of music to be printed in different places at the same time or - to bring to the lecture.

ίο In contrast to the well-known, one The same purpose devices of a similar type accomplish this task in the present invention without requiring a special electromagnet for each Button, or a specially prepared paper tape released; also here is neither a gear train or a drive, nor a synchronous interaction resulting from it mechanically moving parts are necessary.

Below is the device for operating two or more typewriters described with type levers; the same device can also be used for calculating machines without any significant changes, Pianos and the like are used.

On the key lever h (Fig. 1) / there is a contact device b which, when a pushbutton is pressed on the typewriter equipped with an automatic line changer, touches the contacts c in sequence and thereby sends five currents in different directions into the line. Due to the arrangement of the 32 possible combinations of these five currents - with the individual pushbutton levers, the same act with a corresponding automatic change of the current path at the receiving location on five double-legged, polarized electromagnets e ¹ to e ⁵ (Fig. 2) in such a way that with each combination the position the associated armature a ¹ to a ¹⁰ undergoes a certain change, which in turn brings about a shift of the ridges k ^l to ¥ " from their normal position.

The contacts c in Fig. 1 give, for example, the current combination for the letter t, while in the position of the armature a ^l to a ¹⁰ and the combs k ¹ to k ^s, the change in position provided for this letter can be seen.

In the idle state, the line is connected to earth via the windings of e ¹ (FIG. 2); the armatures a ¹ to a ¹⁰ , however, are held by the natural magnetism of the polarized electromagnets e ¹ to e ⁵ on their pole pieces and thereby make with the wire feeds d ¹ d * d ⁷ d ™ d ^is respectively. the south magnetic windings from e ¹ to e ^{5 establish} conductive connections.

The current flow for the first surge is as follows: LB ¹ (Fig. 1), first contact c from right to left, contact device b, typewriter lever h, line (Fig. 2) f ^l a ^x , wire feed d ^l a ¹ , winding of the south magnetic leg of e ^l , feed rf ² , winding of the north magnetic leg of e ¹ earth E.

development of the north magnetic leg of e ¹ its depolarization; the armature a ¹ is thrown off by the pressure of the spring / " ¹ , lies against the approach v ^l and pushes the conductive comb k ¹ to the left.

As a result, e ¹ is now bridged and the second - current impulse now goes from LB ² (Fig. I), second contact c from right to left, bh, line (Fig. 2) f ¹ a ¹ v ^l k ¹ , supply d ^s f ^z a ^s , feed i ⁴ « ⁴ , south magnetic winding of e ² . Feed d ^h , north magnetic winding of e ² to earth. The effect of this current surge is to throw off the armature α ⁴ , which however

only a bridging of e ² , but not also a change in the position. of the comb £ ^{2 is} brought about.

After in the manner described by dropping the anchor a ^% , a ^s and α ⁹ a

ao further change in the current path with a corresponding shifting of the combs k ^s and k ^{s has taken} place, the armature a ⁹ (with negative current transmission a ¹⁰ ) closes a local circuit o ¹ o ² o ³ , windings of e ⁶ (Fig. 1) o ⁷ OBo ⁸ O ⁹ , anchor α ⁹ . .

The conductive combs k ¹ to & ⁵ are thin metal strips which are provided on the front with comb-like incisions (not shown in the drawing (FIG. 2)) and which carry the approaches v ¹ to v ^{10 on the rear.} The extensions t of the pushbutton lever h (FIG. 1) are mounted vertically opposite and movably one above the other in such a way that one or more of their prongs are located in the cutouts n ¹ to ra ⁵ in the normal position.

According to the one for the character to be transmitted

Once the current has been sent, however, the position of the combs is now such that the extension t of the corresponding pushbutton lever is only incised in a known manner on all combs due to the shift that has taken place by electromagnetic means. For this extension, which is designed as an armature for the electromagnet e ⁶ , there is therefore no longer any obstacle to being attracted when the latter responds by closing the local circuit and making the impression.

The pole pieces of the electromagnet e ⁶ are expanded to such an extent that the extensions t of all the pressure levers are opposite the same as an armature.

When the local circuit closes when the armature a ⁹ or λ ^{10 is} thrown off, the attraction of an extension other than the one to be considered for the character to be printed is counteracted by the fact that the other extensions always have one or more teeth of the combs k ^x bis k ⁵ are in the cutouts n ^l to M ⁵ and prevent the extensions of the pushbutton lever from following the train of the electromagnet e ⁶ .

The double rake ρ (Fig. 3) has the purpose of returning the anchors a ¹ to a ^w to their rest position. Its two cross members are arranged parallel to the anchors above the approaches ν ^l to v ¹⁰ and each have five spikes, eight of which are visible in the drawing. . The prongs ^ ¹ to ^ ⁵ are the anchors a ¹ a ^s α ⁵ α ⁷ α ⁹ , the prongs ^ ⁸ to ^ ¹⁰ the anchors a ² a ^ 'cfi α ⁸ α ¹⁰ opposite. When the local circuit is closed, the electromagnet e ¹ located in the bridge is excited and briefly attracts the rake ρ that ends in an armature. The prongs of the double rake press those anchors from a ¹ to a ¹⁰ , which were thrown off, again against the pole shoes from e ¹ to e ⁵ , where they are held in place by natural magnetism.

As soon as the extension t goes up again after pressing with the pressure lever h , the springs r ¹ to r ⁵ automatically pull the combs k ¹ to k ^s back into their normal position.

The described type of power transmission, the automatic change in the Current path, as well as the shifting of the combs achieved by electromagnetic means can also be turned into an automatic one Train fast telegraph, which has the advantage over the existing systems of this type, of a synchronous Gears of two drives connected to one another and of a certain duration or Strength of power broadcast to be independent.

To operate more than two spatially separated typewriters is only required to connect the lines leading to the same parallel to one another.

If it is preferred to use only one line battery, this can also be made possible very easily. In this case, an earth connection isolated from the line is to be attached to the contact device b and the contacts c to be designed as double contacts. These double contacts are then connected to the line battery in such a way that the latter is connected now with the + pole to the line and --pole to earth, and now the other way around between the line and earth of the contact device b.
