by actuating a carriage release lever on the Viagen Joefestig ton or by repeatedly pressing the distance button »

The first option is convenient when in columns with solid Format as written in tables, for example. If, however, the carriage should jump from a given writing position to another, the tabulator must be more laborious Way wiedex-holt set and deleted .v / earth. The second Possibility, the writer has to take his hands off the keyboard each time for the desired movement of the carriage, so that the writing rhythm is disturbed and time is lost. That is why the third option is generally used. It is not necessary to keep your hands off the keyboard to take, but the distance key must be pressed repeatedly until the carriage is in the following position is brought.

Therefore, where the described spacing operation must be performed, manual or semi-electric typewriters are used requires their non-power-driven or manually operated Distance repeat mechanism is able to perform the same function with a single depression of the distance key to be carried out as if it were repeatedly depressed.

It is therefore an object of the present invention to provide a compact spacing repeat mechanism of simple construction for manual or semi-electric typewriters to accomplish"

a rotatable part 56 of, for example, an L-shaped cross-section has begun. The rotatable part 56 is in the engine room attached. If the run distance key 55 is depressed, the rotatable part 56 is thus rotated, the rotation of which in turn results in a rotation via the connecting rod 5 2 of the crank lever 50 counterclockwise (Fig. 1) implemented will. This counterclockwise rotation continues via the connecting rod 49 onto the feed pawl transferring pressing lever 46 so that it rotates clockwise in FIG.

It is now the mode of operation of the embodiment described above will be explained in more detail. If the anchor plate 37 retracted in the manner shown in FIG. 3, the feed pawl 18 and the retaining pawl 19 are grounded by the tension springs 21 and 23 brought into the position shown in FIG. The engaging portion 18c is released from the escape wheel 16 while the Engaging portion 19b comes into engagement with the same and the Carriage 34 holds. If the anchor plate 37 moves forward during the writing operation of a type rod (not shown), so the lock 29, as shown in FIG pushes the depressed arm 18d and rotates the feed pawl against the tension spring 21. This becomes the engaging portion 18c of the feed pawl 18 brought into the range of rotation of the escape wheel. At this point, the retaining pawl 19 is through the Stopper 18f pressed and rotated in the same direction. As the escape wheel 16, so that the engaging portion 19b from Escape wheel 16 is released and the escape wheel 16 can continue to rotate until it engages with the engaging section 18c. This allows the carriage 34 to move half a tooth pitch. This results in the position shown in FIG. 4. Will the type bar returned to its starting position after writing, and consequently the anchor plate 37 withdrawn, so the feed pawl 18 is rotated by the tension spring 21 until

it touches the stop pin 32. This releases the engagement portion 18c from the escape wheel 16 and pushes the trigger 24 by the depressed arm 18d. On the Following feed pawl 18, the holding pawl 19 is rotated by the tension spring 23, so that the engagement portion 19b of the Holding pawl 19 arrives in the area of rotation of escape wheel 16. So that the escape wheel 16 can continue to rotate until it nit the Engaging portion 19b of the holding pawl 19 comes into engagement and the carriage 34 moves further by half a tooth pitch., away. The escape wheel 16 is thus returned to the position shown in FIG. 1. With each executed by the type bar During the writing process, the feed pawl 18 and the Ilalt pawl 19 come alternately into and out of engagement with the escape wheel 16, so that the carriage can move one tooth pitch with each work cycle.

The distance key 45 becomes the repeated distance switching is used, the result is essentially the same sequence of operations as above. If the distance key 45 is pressed, so the spacer lever 38 is made by the connecting rod 42, the rotatable member 44 and the connecting rod 41 in Pig. 1 rotated clockwise so that the trigger 24 by means of a further connecting rod 41 clockwise turns. As in the previous case, the feed pawl 18 and the holding pawl 19 therefore move into that shown in FIG. 4 Location. If the distance key 45 is released and returned to its original position, the reverse operation takes place compared to when the distance key 45 is depressed. The spacer lever 38 and the trigger 24 are together in Fig. 1 rotated counterclockwise and the feed pawl ynd the retaining pawl 19 go into the position shown in Fig. 1, so that the carriage 34 moves one pitch. ·

If in the state shown in Fig. 1, the Dux chi -Abstand button 5 5 is depressed, the crank plane 50 is rotated counterclockwise by the connecting rod 53, the rotatable part 56 and the connecting rod 5 2 and the The lever 46 pressing on the feed pawl is threatened by the further connecting rod 49 in a clockwise direction. As a result of the rotation of the lever 4G, the feed pawl 18 is rotated against the tension spring 21 under the action of the tension spring 48 and the engagement section 18c of the feed pawl 10 is brought into the range of rotation of the escape wheel 16. At this point, the retaining pawl 19 is pressed by the stop 10f and rotated in the same direction in which the escape wheel 16 rotates. Thus, the engagement section 19b at the escape wheel 16 is released. Accordingly, the escape wheel 16 rotates further until it comes into engagement with the engagement section 18c, so that the carriage 34 can move further by half a tooth pitch. This state is shown in FIG. In the state shown in Fig. 5, the force acting on the Viag en 34 in the writing direction is transmitted via the rack 36 and the spacer pinion 15, so that the escape wheel 16 threatens to turn clockwise, the feed pawl is rotated in the direction in which the tension spring acts against the tension spring 48 as a result of the teeth of the escape wheel 16, which is in engagement with the engagement portion 18c of the feed pawl 18, so that the engagement portion 18c is released from the escape wheel 16. At this time, the holding pawl 19 is rotated by the tension spring 23, following the feed pawl 18, so that the engagement section 19b of the holding pawl 19 is brought into the range of rotation of the escape wheel 16. The escape wheel 16 can thus continue to rotate until it comes into engagement with the engagement section 19b of the retaining pawl 19, as a result of which the carriage 34 can move further by half a tooth pitch. The position shown in FIG. 6 is thus reached. If the passage distance key 55 is not pressed even in this state, then the lever 46 pressing the feed pawl is in the clockwise direction

Position, so that the feed wheel 18 is rotated against the tension spring 21 and the feed pawl 18 in turn against the tension spring 21 is rotated so that the state shown in Fig. 5 is obtained. By repeating the operation described above the feed pawl 18 and the retaining pawl 19 can repeatedly come into and out of engagement with the escape wheel 16, namely by the tension spring 48, which by the engaging portion 18c of the feed pawl 18 together with the teeth of the escape wheel 16 exerted cam action and the tension springs 23 and So the passage distance key 55 is depressed, the carriage 34 drives at a prescribed speed automatically and continuously from a continuous distance movement.

If the passage distance key 55 is released, the reverse process takes place as when it is depressed. The who The feed pawl pressing lever 46 is turned counterclockwise rotated and brought back into the position shown in Fig. 1, so that it is out of rotation to the feed pawl 18 by the tension spring 48 is released against the tension spring 21 and the pass-through distance movement of the carriage 34 is interrupted.

If a type key or the space key 45 is depressed so that the release 24 rotates and the engagement portion 18c the feed pawl 18 comes into engagement with the escape wheel 16, the teeth of the escape wheel 16 exercise together with the engagement portion 18c has a squatting effect. At this time, the contact wheel 26 of the trigger 24 contacts the depressed arm 18d the feed pawl 18, so that this cam effect is restricted or canceled and the type key or the distance key 45 is released from the depressed state, and so the engaging portion 18c is not released from the escape wheel 16, until the dissolver 24 is returned to its original position * In this regard, the lowering

pressing the scroll distance key 55 has the advantage that the The cam effect is fully utilized, since here the; The trigger does not act. For example, it is the scroll space key 55 accidentally depressed when a type key or the space key 45 is also depressed, so this brings the trigger 2 4 into action and the Cam action canceled. This has the advantage that an uncompleted repeated spacing movement of the carriage 34 is prevented.

In the embodiment described above, the wax can reliably perform repeated spacing rubbing movements, as the Escape wheel 16, the feed pawl 18, the>! Retaining pawl 19 and the lever 46 pressing the feed pawl are attached to the base plate in such a way that they are in parallel with this Moving levels, the whole mechanism can be made flat and compact. This embodiment is therefore for portable typewriters well suited, which should be as small and light as possible.

Fig. 7 shows another embodiment of the present invention. The parts of this figure that correspond to FIG. 1 have been given the same reference numerals, a repeated one Description is unnecessary. Fig. 7 differs from Fig. In that half a part 18a of the feed pawl 18 on End with an inertial mass 57, for example a weight is provided. If the weight 57 is absent, as in FIG. 1, the weight of the feed pawl 18 and the force of the tension spring are the same 48 not tuned in the correct manner, so that the engagement portion 18c of the feed pawl 18 relative to the Escape wheel 16 engages or disengages much more quickly than usual, so that carriage 34 traverses excessively quickly and the carriage 34 runs beyond the prescribed stopping position when the passage distance key 55 is released.

As a result, the carriage 34 moves at the correct speed as it passes through, each time is equal to. a letter spacing. Another advantage is that it is reliably prevented when the scroll button is pressed is that the carriage 34 moves beyond the desired stick position.

Fig. 8 shows a third embodiment of the present invention. The embodiment of FIG. 8 differs from that of Fig. 7 in the following manner. The pen holder strip. 46a at one end of the lever 46 pressing the feed pawl is omitted and a spring holding part 58 is provided in its place, which has an elongated hole 58a, which is in Extends the longitudinal direction of the central part. A spring retainer strip 58b is disposed at one end. The spring retainer 58 i.'3t by means of a screw 59 inserted into the elongated hole 58a at one end of the one pushing the feed pawl Lever 46 attached. Between the spring retainer strips 58b and the tension spring 48 is tensioned at the end of the half part 18a of the feed pawl 18. The attachment point of the spring retainer 58 can be adjusted by loosening the screws 59, so that the force of the spring 48 acting on the feed pawl 18 can be adjusted istc. This can reduce the speed of response to the by the tension spring 48 and the engaging portion 18c together the squatting effect exerted with the escape wheel 16 can be varied, so that the wagon 34 passes through at the desired speed t.
