This changes the length of the lever arm in pieces with a pointer connected to a pinion to form a transmission lever which coincides with the pointer, the pinion being actuated with a pen or a pen. The attached pinion is in mesh with every measurement,

is cut open in a special way to accommodate the head of a control system (Figs. 7 and 14) which converts a circular movement into a linear, non-uniform movement, the stroke of which is equal to the distance P per full revolution of the said head (Fig. 13) . These zero groups are engraved at precisely predetermined locations on the dial 56, these locations corresponding to the position of the windows of the fixed dial 45 (FIG. 8). The number of zeros in each group gives the maximum value of the yardstick coefficient, although this number can be changed in any case.

The control system of the movable dial 56 consists in the present case of one Adjustment knob 63 which is provided with a slot 62 for a screwdriver. The button 63 forms a part of a cylindrical body 66 which is constricted so that it has a driver 65 and a having semicircular approach 66 a.

The body 66 has, on the one hand, a locking cam 64 and, on the other hand, an axial bore for receiving a compression spring 68. Otherwise, the setting knob is constructed like the others Parts of the adjusting pinion 17 of the first-mentioned embodiment. The device also has the same means for switching the speed, for coupling and uncoupling the sliding pinion. These means are not shown in FIG. 7 and will not be described again here.

This embodiment according to the invention operates as follows: When the adjustment knob 63 z. B. by means of a screwdriver, which is inserted into the gap 62, is pressed, the locking cam 64 is provided from its in the bearing plate 37 a Layer brought under the bearing plate. This, as in the embodiment described above the coupling connection between the sliding gear and the speed change gear solved. Then the adjustment knob is turned, this turning the movable dial 56 shifts so that the selected scale in a corresponding window of the fixed Dial 45 appears. During this rotary movement of the adjusting knob 63, the driver penetrates 65 into one of the cells 70 of the curved opening 61 and moves the movable one Dial by one or more divisions according to the number of revolutions of the Adjustment knob 63 to obtain the desired marking or scale.

When this mark is indicated, the locking cam 64 is again in its correct storage provided in the bearing plate 37a, and it is sufficient not to press the setting knob 63 to exert further pressure so that it lifts itself a little to return to its rest position and locked automatically. At this moment there is the semicircular extension 66 a in one of the cells 70 of the opening 61 and locks the movable dial in that position in which she was brought.

The motor pinion M can instead of a timing device (as in the described embodiments) also be connected to a movable part of a reading device, wherein the reading scale can be changed in this way and at the same time displayed by the device according to the invention.
