The invention relates to a program-running four-species calculating machine to create a program switching device for the manually variable work program switching device, which are all in Sequence control of combined machine aisles in connection with at least two complete Calculating machines, which one with switching and arithmetic processes, in particular a multiplication Control cams for pressing in and pressing out 5 and a division incidental work steps Setting, amount switching, counting, storage and printing without special switching of the program shaft in works, as well as their drive, control and transmission in the correct sequence, safe for processing have transmission members provided program wave, brings, eliminates the disadvantages mentioned, cheap in which is manufactured via differently toothed indexing gears, requires little space and moreover A machine-driven slide drive in io reduces the manually operated radio intervals is switchable. structural members are permitted to a minimum. Besides that For the automatic processing of machine work, it should be possible to repeat a partial work step program switching devices have already been fetched without first running the entire program knows that allow for the sequential control of different parts.

Working steps with switching and control cams are provided for this purpose Have program shaft, which the partial wheels of the program shaft parallel to each other in operations such as drawing in the factors, whose output is arranged on the machine, with spring-loaded continuous printing, Processing of an entered value with switching pawls, individually via function keys etc. prompted in rhythmic sequence. This releasable slide is assigned, which at a andie Program wave by pressing the respective closing, the automatic value entry or a The rotation of a machine function key that initiates or triggers the output of values in the machine processes via a mechanical main shaft through the machine-driven one engageable clutch with the machine drive slide drive one each two switching steps of the can be connected and runs smoothly with the rake program shaft corresponding stroke movement auswerkswelle around. 25 lead, in which they use the indexing pawls To carry out several different program waves in one, through the machine aisles on top of each other the program wave is selected by beta following the actuation of the function keys term the program executing the respective machine operation in the different key before the machine drive starts up in a sequence of steps in such a way that move axially to the left or right one or two steps further so that the probar, whereby a program change takes place.

In the starting position shown, a capacity safeguard blocks. In the On the development of the program shaft 36, the pawl 49, the cam 66 (FIG. 2), rests on the inserted pins 67 a beveled part of the locking disk 48 35 NEN in position I of the program shaft 36 of the deletion on. The decimal point slider 15 can thus be displaced unhindered by the amount switching mechanism 29 (FIG. 1) and the readiness switch. If, however, the program shaft 36 is rotated to adjust the said switching mechanism 29 for value, so the locking disk 48 presses the pawl. To achieve precise switch positions and

Instead of to be changed. the bevel of the locking disk 48 on one side

According to FIG. 2, the perogram shaft 36 is designed as a profile according to FIG. 1, the locking disk 48 according to FIG. 2 is designed with a fil shaft, namely as a square shaft. Provided on incisions 69. The switching and control cams as well as the 45 48 is, as already described, the comma incremental wheels 38, 39, 40 pushed on by clamping, the preselection slide 15 (Fig. 1) is axially fixed in the positionsI by shaft locks 53 via this locking disk and locked up to V.

The Pro (Fig. 2) attached progression wheels 38, 39,40 has gram shaft 36 is in twelve individual steps of each the progression trad 38 a tooth 71 in position II 30 ° rotatable by 360 °. Six steps each encompass the full program (ie offset by 60 ° from the rest position), ie 180 ° rotation are sufficient for one tooth 73 in position I for the indexing wheel 39 to run a program, the second 180 ° opposite (ie by 30 ° opposite offset from the rest position) speak the first 180 °. Accordingly, reproduction and the indexing wheel 40 has four teeth 74 on the racks Get the indexing wheels 38, 39,40 in the two lungs III to VI (120, 150 and 180 ° ten half that at 90, in their toothing, the switching and 55 offset from the rest position). The curve shape of the teeth of the control cams. In the following second half of the indexing wheels 38 to 40, only half a revolution is designated by the digits 71 ', 73' and 74 '. Considered for progression lungs I to VI. In the rest position, the wheels 38 to 40 are used, as in FIG. 1, the program shaft 36 is already in position VI. To work would be explained, transport pawls, each consisting of follow-up control, the following switching or 60 a slide 41, 42 or 43 and a cam disk are provided: A cam disk 55 articulated indexing pawl 72,75,76 exist to prevent the pen slide in The pawls 72,75,76 are under the train on position III, IV and V, which enables, while the springs 77 attacking them, to progress through a tensile 38, 39, 40 or their Teeth 71; 73; 74 on, keyboard 1 (FIG. 1) already has a new value in the 65.
