Device for measuring large diameters on objects
factories.
It is known to measure diameters by determining the length of the tangent which corresponds to a determined angle and
<EMI ID = 1.1>
The device according to the present invention allows the measurement of large diameters with high precision; we determine
<EMI ID = 2.1>
known by the fact that the distance from the 'point of intersection of'
<EMI ID = 3.1>
small, at the point of contact of one of these tangents with the surface of revolution is measured, the point of contact being determined according to the present invention as the midpoint of
<EMI ID = 4.1>
measuring boxes or feelers, which indicate the spacing of the tangent or a line parallel to the tangent with respect to the measured surface of revolution. ' If the indications of the two masure'se devices correspond, 'their points of contact with the surface of revolution delimit a segment of a circle whose vertex is also distant from the two points of contact and coincides with the point of contact of the tangent.
A similar device 'is shown in the accompanying drawing.
