Description

a) The combination device consists of the main joint parallelogram (l) and the eP parallelogram (2), both of which are ideally connected in such a way that the pole formed as a pivot point (3 the Both Gelmk parallelograms (1 and 2) can be positively controlled according to any templates via the travel arm (4) and drive pin (5), whereby a drawing device (6) supplies true-to-scale drawings according to the setting of the main articulated parallelogram (1) on the leg (7) of the measuring parallelogram (2) a according to the driving pin guide (5) integrating measuring roller (8) in the manner of the planimeter measuring mechanism, can at the same time and in one operation according to any template a scale drawing and a B) It is true that in Austrian patent specification No. 3217 an area measuring device has been identified with a "possible" pencil combination; but it is this device is a small area measuring device as with the well-known polar planimeter a) the driving pin, pivot point and measuring mechanism are arranged on the same arm, the driving arm, and b) the measuring roller always travels over the surfaces to be measured. There are also known reduction polar planimeters that for the purpose of "reduction" in the well-known polar Planimeter L-linkage a joint parallelogram between- have arranged, however, to bypass and measuring area still more and more essentially for the purpose of higher measuring reduce sensitivity. With these devices, too, the measuring roller travels over the area to be measured.

Furthermore, the terminus technicus "pantograph planimeter" has entered the literature, which in turn are reduction planimeters.

The technical peculiarities of these devices are: a) they are small area measuring devices, whose area measuring units b) always use the plans, drawings etc. to be measured! c) The combination device on which this application is based is completely different: Due to the arrangement of the main parallelogram (1) with travel arm (4) to pole 3). on both sides, but Measuring parallelogram (2) with leg (7) and integrating measuring roller (8) on the side of the pole (3), the measuring roller (8) can never drive any templates, drawings, plans etc. to be processed and thus always receives its own consistent, suitable underlay, which, as is well known, is very important. d) Furthermore (since the measuring roller (8) does not interfere with the templates to be processed) it is not only possible to process drawings, plans, etc., but also templates with very high cut edges or templates with significantly fluctuating heights and surface structures. - e) -e) In addition to these important features mentioned in points a), c) and d), there is another one that characterizes the device as a combined large area measuring and drawing device and that is based on the concise arrangement of the double-joint parallelogram (1 and 2) to point c) and the criterion of the measuring parallelogram (2) leading the leg (7) with measuring roller (8), which is arranged in such a relationship to the main parallelogram (1), that - in contrast to the developments mentioned under point b) - the large area measurement is possible in addition to the drawing function up to 20,000 cm in a "closed line", or also by effortless connection- measurement smaller 92 individual templates that belong together up to 20,000 cm total area without readjustment of the measuring mechanism can be measured.

Ultimately, the variable parallelograms (1 and 2) variable sign and measurement results. f) To further precise scale drawings the drawing device (6) of Figure 2, Appendix 3, is not like e.g. with pantographs usually equipped with pencil leads, but with light ones exchangeable, so also colored ball fine line refills.

This drawing device (6) sits in the center of the joint of the main parallelogram (1) and consists of the spindle (9), the compression spring (10), the knurled knob (11), the knurled screw (12) and the mine (13).

With this arrangement, the mine (13) is only pushed through the top and held down acting spring (10) so that the mine (13) is resilient on the one hand slides over the drawing paper, on the other hand easily manually or through any Mechanism can be lifted off the drawing surface; ultimately then about the Knurled screw (12), which acts on the compression spring (10) holding the lead (13), that there is a more or less strong outflow of paint due to the pressure.

This technical arrangement is very desirable for several reasons, to think that e.g. more pressure is required when copying through multiple drawings will ; but also if you want a stronger drawing, etc. Anyway how the pencil drawing is disadvantageous if a photocopy or similar is made of it shall be.
