Description

Device on typewriters for returning the car to the Middle position and to fix the carriage in this position For fast It is the readiness of typewriters and an equally fast locking option In the currently known versions, it is a hindrance that on the one hand prior to commissioning after opening the case lid, the center lock of the car is released and before closing of the case lid are brought back into engagement and also the car again must be brought into the middle position. This requires a number, separate ones Handles. The invention eliminates this disadvantage in that the individual members a device on typewriters for returning the car from the left to right or right to left in the middle position and to fix the carriage in this position by inevitable connection with the devices to open and closing the case simply by opening and closing it. of the case lid be operated in such a way that when the case is closed, the center lock is the first brought into a snap position, then the inter-carriage lock is triggered, so that the carriage, when it is to the right of the center, is due to the tension of the carriage extension spring slides into the center lock to the left or, if it is to the left of the center, continues a device is actuated, which the Wagen_ ent = against the carriage tension spring to the right also leads to the center lock, 'where he also. at complete closed case remains locked and when opening the case briefly before the opening movement has been completed, first activate the vehicle interlock switched on again and then triggered the center lock and '. the device for returning the trolley from left to right or its stop or driver is guided all the way to the left, so that the car with the case fully open by the feedback device in, in no way affected in its normal operation or is prevented.

Devices @ on typewriters where, by pressing a Lever or simultaneous actuation of two levers with one handle of the paper trolley, regardless of whether it is to the right or left of the center, anywhere is well known per se; however, they do not work within the meaning of the invention together with the devices for opening and closing the case lid. Further are also devices known on typewriters, through which the machine when opening the lid in the working position and when closing the same in Is brought to rest. Devices for returning and fixing the carriage are not provided for here.

The drawing shows only a basic arrangement of the device according to the invention, and only up to the link (lever) with the devices to open and closing the case lid inevitably connected is that, however, can also be operated by hand to have the same effect as by opening and closing the lid.

The parts of the device work together yva "follows: If the lever is, for example, '#' rotated in the direction of the arrow, it takes the slider c with it, pulls it forward in its guide b, so that one bottle e des Pulley block e, f is pushed to the left. The rope. Of the pulley block acts via pulleys on the carriage and, if it is to the left of the middle position, pulls it against the tension of the carriage tension spring into the center lock, which already occurs when the movement of lever a was released by this to the locked position.

Against. End of the rotary movement of the lever, a releases a driver td, which is attached to the slider c, the inter-car inter-car lock h from (similar to as when pressing the tabulator), so that the car, if it is to the right of the center lock stood by the carriage spring is guided to the left in the 1Vfittensperre.

If the lever is now turned against the direction of the arrow, then the movements described above in opposite directions, d. H. the slider'c is to the rear out, .the release of the inter-carriage lock k is canceled, the pulley, which is kept taut by a spring g, goes back to its starting position, and the wagerimenter lock i is withdrawn from the locked position, so that now the carriage is released for its normal operation without any Parts of the device influence or hinder him in his work.

Claims (1)

PATENT CLAIM: i. Device on typewriters for repatriation des-carriage from left to right and from right to left in the middle position and for fixing the carriage in this position, characterized in that the individual members of the device by inevitable connection with the devices to open E the case can be closed by simply opening and closing the case lid rt be actuated that when closing the case, the car center lock first brought into. Snap position, then the inter-carriage lock is released, so that the carriage, when it is to the right of the center, is the result of the carriage tension spring slides into the center lock to the left or, if it is to the left of the center, continues a device is actuated that the carriage against the carriage tension spring tension to the right also leads to the center lock, where it also leads to completely , closed case remains locked and when the case is opened briefly Before the opening movement is complete, first activate the inter-carriage lock switched on again and then triggered the center lock and the device for returning the carriage from left to right or its stop or driver is guided all the way to the left, so that the car with the case fully open is in no way affected by the feedback device in its normal operation or is disabled. a. Apparatus make claim z, characterized by the use with typewriters, where the machine moves out of its rest position when the case is opened in .the working position and when closing the case from the working position in the rest position is brought. 3. Device according to claim i, characterized in that da.ß to their actuation in the same sense as in opening and closing of the case and regardless of the opening and closing movement a special one Lever is provided.
