Description

migen star possesses, rotatably arranged. The arm 13 carries the stop knife 14, which is set with the Reitern 15 cooperates with the TeUung »δζ. The tabulatonnesser 12 ΐ £ # both at the tabulator position as well as in the rest position under the action of a spring 20 on the control pawl 5. The control rail 22 is pivoted away, and the roller 17 on the arm 16 remains in both positions the control rail 22 out of engagement.

The smallest division of the font that is written on a typewriter, in which the erfindungsaemäßc Tabulieremrichtung is built, should z. B a = 2.12 mm step size. The typewriter can also be switched to one or more other step sizes, eg b = 2.54 mm and larger. Switching takes place by setting a lever on the machine to the desired step size, for example if the lever is set to 2.12 mm pitch, the control rail is shifted in parallel over the entire writing material, so that it is out of engagement with roller 17 comes as shown in FIG. The oscillating relative movement of the stop knife 14 is necessary to accommodate the different pitch of the indexing rack 21 - z. B. 2.54 mm division - to the division of the tab 15 - in this case 2.12 mm division to compensate. In the illustration shown in FIG. 1, the indexing rack 1 is in the working position with a 2.12 mm pitch; the tab spacing a, which is based on the smallest step size, is also 2 12 mm. In FIG. 2, which shows the tabulation position, the indexing rack 21 is located

Claims (2)

Claims: be divided. This arrangement is not only complex, but also difficult to manufacture. 1. Tabulating device for on two or more In addition, it is due to the different different switching step sizes switching distances of the tabs, easier possible that with tabare Typewriters or similar machines with bulging out position errors occur. exchangeable type carrier, with a switching The invention is based on the object of creating a number of tooth tabulation direction corresponding to step sizes, which is equipped with a rider graduation on the indexing racks and rail, as it is also in machines with a tabulator knife for tabulation is used with only one step size,
ter, characterized in that the ι ο This task is achieved according to the invention by the stepping rack (21) with the smaller one solves that the stepping rack with the small number of teeth one with the tab knife (12) in ren number of teeth can be brought into operative connection with the tab knife control rail (22) which can be brought into operative connection with curves and provided with curves in such a way is assigned that the control rail is associated with the between the rack division against the equalization against the rider division equalizing rider division, additional Relativbechende additional relative movement is granted, movement is granted, the division of the rider of the where the division of the rider (15) the division of the division of the indexing rack with the largest indexing rack ( 1) with corresponds to the largest number of teeth,
nezahl corresponds. The advantage that can be achieved by the invention is there 2. Tabulation device according to claim 1, in particular that also for writing or ähndurch characterized in that the tabulator knife loaned machines with two or more step sizes (12) is rotatably arranged and on an arm and exchangeable type carriers the same taboo (16 ) one on the curves that can be used as a movable device in the machine frame, when switching over to typewriters without this device to switch over the division with a larger number of teeth to a different step size,
pivotable, control rail (22) running along with reference to the drawings, roller (17) is shown below. an embodiment the invention is 30 ben. It shows 1 shows the tabulation device in the rest position; it is the rack with the largest number of teeth in the working position,
F i g. 2 the tabulation device in tabulation position; The invention relates to a tabulator for 35 there is another rack and the associated rack on two or more different step size control rails in working position, one rider is ßen switchable typewriter or similar machine sets, with exchangeable type carrier, with one of the F i g. 3 the same tabulation device as in Switching step sizes corresponding number of F i g. 2 in stop position, Tooth pitches on the indexing racks and 40 F i g. 4 the correct sequence of the tabular with a tab knife for the tab tabs. tion of the tabulation device according to FIG. 2. All riders For machines with single step switching, can are set. through the interaction of the riders with the In F i g. 1 is with 1 the stepping rack with Pawl any desired position, in addition to the division »α«, in which the pawl 2, will; each tab position corresponds to a 45 which is constantly held under the action of the spring 3 Tooth on the stepper rack. Otherwise this will intervene. The pawl 2 is a BoI-bei Machines that have the ability to switch zen 4, which is located in a writing slit, on one or more other switching steps offer rotatable bearings and is rotated when writing to the respective and where the type carrier is exchangeable. If the required number of teeth is switched on, Such machines should not only be based on type 50 This indexing mechanism is in the most varied ger against another with z. B. letters, numbers known and for this reason not len, special characters or their combinations are shown in more detail. There is also one around the bolt 4 same step size, but also against a type control pawl 5 by means of a moving device carrier with a different step size, e.g. B. 2.12 mm towards the writing carriage extending oblong 2.54 mm or another pitch can be interchangeable. 55 ches 6 rotatably mounted. At the bottom of the tax it is necessary for each division a notch 5 is an angled nose 7, the Provide step-by-step rack and with which engages under the pawl 2, so that when turning Bringing pawl into engagement. the control pawl 5, the switching pawl 2 is also lifted A well-known tab device (German Aus is and so the switching tooth 8 of the pawl 2 off Legeschrift 1 815 871) for typewriters with 60 the indexing rack 1 is lifted out. In Exchangeable type carrier is with a step switch- this rotated position of the control pawl 5 is double rack, which corresponds to the one on the one hand by one under the action of a attached type carrier either with a spring 9 standing double-armed locking lever 10 or other interlocking in actual action to one latches. So that the locking lever 10 has a certain Ratchet is brought. However, it does not have to exceed 65 rotation distance, it is supported by a only limited division-correct tabulation and limit stop 11 in the pulling direction of spring 9, of the one as well as the other step, the rider on the other side of the control pawl 5 is on this rail of the tabulator at different distances a tabulator knife 12, which has the shape of a three-ar-
