Description

BASIC Auth. St. No. 86600 describes a vernier caliper and ruler with embossed scale divisions, allowing us to only measure parts.

The design is prepared in that the calipers on the calipers have relief divisions for mounting a scale ruler on them, equipped with relief divisions and an edge, interfering between the divisions of the sponges, which allows not only to measure, but also to draw blind, for example, four -trollers

FIG. 1 depicts a vernier caliper with embossed scale divisions; in fig. 2 - edge.

Ready for relief drawing, the blind contains a caliper in which instead of scratches for measuring millimeters on the scale bar / squeezed, soldered or made by other known methods, pins 2, past which the slider 5 is moved by the vernier 4.

On both calipers 5 calipers are embossed scale divisions 6, allowing us, blind, to set edge 7 so as to measure or draw, for example, quadrangles.

Working with a caliper is as follows.

The slider 3 and the scale ruler Y provide the installation of the jaws 5 on the three edges of the measured part, after which the edge 7 is superimposed on the fourth face. The edge 7 is equipped with pins 8 and a tongue 9 that fits between the relief scale divisions of the 6 jaws 5.

Subject invention

Ready for relief drawing blind by ed. St. No. 86600, which differs from the fact that, for the purpose of measuring and tracing, for example, quadrilaterals, it uses a caliper with embossed divisions, also applied on its jaws, to install along it a ruler equipped with embossed divisions and an edge placed between the divisions mi sponges.
