Description

GERMAN

In telex, it is often desirable to have the message on a specific form, such as z. B. on an invoice form, form with static information, etc. is written. To do this will be Forms used, which are arranged one behind the other on a paper web and for their Transport z. B. have holes on both sides. It is imperative that the location of the form is the same with respect to the print location on the sending and receiving apparatus. Otherwise the message would not be in the correct place on the form of the receiving subscriber Printed on the form.

In order to have concurrent, i. H. to achieve synchronous movements of this paper web, must check the operators on the sending and receiving sets before starting a message At the sending and receiving locations, the forms on the paper web are in the same position with respect to one another bring. However, this assumes that the receiving station is busy; H. that an operator is present, which at the beginning of the message put the form in the right place (setting to a Identification mark) moved by hand. In order to be able to achieve a form synchronism without An operator must be present at the receiving location, it is known that the form equation in a direction perpendicular to the direction of the line by a feeler depending on the position of the Control form paper. It is also known to use the feed in such form writers automatically by a predetermined number of line feed characters.

To now this form synchronism for both the sending and receiving participants to achieve, both by a predetermined number of line feed characters and by means of a sensor that comes into effect depending on the position of the form paper According to the invention, it is proposed that a locking lever be influenced by the actuation of the "Wer-da" key and is locked by a pawl that moves the stepping pawl and the pawl into the The ratchet wheel of the line counter can collapse and after pressing the line change and permanent key the Line feed lever over the stepping pawl the line counter and a linkage, pull pawl and Ratchet wheel advances the pressure roller until the paper sensing contact takes effect.

The advantage of the invention is that the paper transport through the known paper control contact is interrupted while the counter counts the number of paper transport steps until finally after reaching the maximum required set-up

number of steps the permanent button is electrically or mechanically disabled.

Instead of the permanent key, a special key provided for this purpose can also be used. The counter is adjustable so that the number of line increments to be counted corresponds to the The size of the forms can be changed.

The device according to the invention has the advantage over other known devices that they can easily be used on teletypewriters connected to the public teleprinter network are connected because no special functions are sent out or carried out that the normal would interfere with public dial-up traffic, even if a with the inventive Establishment of equipped teleprinter is connected to a standard teleprinter.

The structure and the mode of operation of the device according to the invention for producing the form synchronism is described using an exemplary embodiment with reference to the drawings (FIGS. 1 to 6).
Tn Fig. 1, a known paper web T is first shown, on which adjacent forms 5 'are printed. The forms can be separated along a perforated line 6 'after being written on with the teleprinter. The paper web has transport holes 1 ' on both sides, and each form printed on the paper web has an identification mark 4' and a paper contact hole 2 '. At the sending teleprinter, the form to be written with the identification mark with the marking 3 'on the teleprinter is in agreement.

3 4 brought mung (Fig. 1 a). The telex of the calling subscriber on the other side has the the form can be moved in any position in the remote control unit, which is engaged via lever 2 scribe (Fig. Ib). Tooth advanced. A line feed finds The teletype machine of the remote station is then called, but not instead, because it is called for the function, and both teletypewriters start up. 5 Process "Who is there" - "Here is" that took place beforehand Then on the calling teleprinter, the number line transport is struck on the cam disk 24 so far that it was turned in front of the "Who is there" key that the feeler lever 21 that must be pushed. When the "Wer-da" - inclined right surface of the groove 23 is pressed. The push-button is the engaging push rod, which is designated with 1. Here the contacts C ₁ d have been closed, net is actuated by the pull rod "Whoever there" and takes OK and the relay 2 (Fig. 4 and 6) picks up. When the Andes lever 2 from the dot-dash position to pull the electromagnet armature, the coupling position according to FIG. 2 is also. In addition, at lever 53 between lever 54 and lever 6, the teleprinter called in this way is released in a known manner that triggers the name giver through the line feed lever 7. and latch 5 is transported further, but a line The feed through the roller 3 on the lever 2 via the pin 4 15 via the rods 51, 52, pull pawl 50 and stepping switching wheel 58 of the pressure roller 59 lifted out of the ratchet wheel 27 does not take place. At latch 5 on the lever arm 6, which can act on the push rod of the called teleprinter, however, for the line feed 7, and the line feed takes place until the sensing lever 56 in through the nose 10 on the lever 2 via the lever 9 out of the contact hole 2 'of the paper web 7' can fall, the ratchet wheel 27 lifted pawl 2 fall 20. The magnet 2 unlocks the coupling pawl 53 and the line counter consists of a ratchet wheel 27 which interrupts the line feed. The counters in the stepping pawl 5, the pawl 8 and that of the sending teleprinter as well as in the emp-coupling lever 2 as well as the sensing lever 21 on the intercepting teleprinter on the opposite station run the cam 24 and the spiral spring 25 The release pin 46 by the coupling process of this line counter (falling of the run on the lever 14 lifts the pawl 13, pawls 5 and 8) are released by briefly lifting the Verder locking pawl 13, which is under spring action 16, with the tooth 18 on the locking lever 2. This lever 2 jumps back to its starting position in lever 2 via the contact pimple 19 and brings the contacts α, b (FIGS. 2 and 6) closed for a short time. 30 pawls 5 and 8 out of engagement with the teeth of the The electromagnet 1 (Fig. 5 and 6) pulls for short ratchet wheel 27. Here, the ratchet wheel 27 jumps and moves over the magnetic linkage (armature with its cam disk 24 under the action of 48 , Lever 29, Shaft 30, Lever 31) Drawer 32 the lever 33, tensioned by counting the line increments, to the left and releases the latch 37, the coil spring 25 in its starting position also with the "Wer-da" key Lever 35 back. When the pawl 13 is raised by the 42 and 41, the lever 39 rotates to the right and here the trigger pin 46, the contacts a, b are closed, via the lever 37 and the trigger lever 47 the electromagnet 1 attracts and sets the permanent name giver triggers. At the same time, the clutch button 35 engages the single-turn clutch 43 via the magnetic linkage 29, 30, 31, thrust pressure lever 40, tab 32 and clutch lever 33 out of operation, and the transmission drive shaft 45 takes the transmission control 40 single-turn clutch 43 with it when the clutch bushing falls . On the form of the teletypewriter pressure lever 40 the sender drive shaft 45 from the remote station and on the form of the other send control socket 44. This is for the operator calling teleprinter, the name of the calling telex operator is now written as a sign for the called telex subscriber. The teleprinter that the form of the teleprinter on the counter-called teletype presses now automatically 45 is in the same position as the form of his carriage return and the line change and is located on the teleprinter. He recognizes this state of the "here is" sign. The name of the called pelten sender antriebswelle 45 is now written on the calling and called purely acoustically by stopping the decup teleprinter. This state can be written by the subscriber. Up to now there is no simple acoustic (buzzing) or synchronism of the forms on the sending and receiving 5 ° visually (lighting up a lamp) available, and on the described first form on the reception side is the patent claims:
Written text has not yet been written down in the designated place on the form 1. Device for automatic form matching (Fig. Ib). In order to now bring the form of the teletypewriter 55 position for teleprinting machines, with the uninterrupted number of lines in the same place as the calling subscriber, feed characters are sent and the transport of the is hit the line change key and on it form paper a paper sensing contact the persistent key 35 (Fig. 5) is pressed. With the remote interruption, characterized in that the calling subscriber writes, the shortcut 60 is closed with the actuation of the "AVer-da" key, since the sensor 56 influences the locking lever (2) and a Contact hole 2 'of the paper web 7 is locked when the pawl (13) is set, which could occur the step on the identification mark 4' (Fig. La). In the pawl (5) and the pawl (8) in the Fig. 4, the contacts g, h are now closed on this remote ratchet wheel (27) of the line counter.
