Description

The invention relates to a device 45 by connecting the crosshairs of the visor with the for alignment one behind the other to be laid Lei cross-slot of the bearing cross brought into congruence Alignment pipes on an alignment line to be used is a simple and time-saving alignment Longitudinal axis with two sighting devices, two or more one behind the other at the ends of the laid and the pipe to be laid.

It is already known such a device that the pedestal has a curvature (see US Pat. No. 3,116,557), but which has the disadvantage of greater complexity, since it is provided with the footprint that is adapted to the inner wall of the pipe. In this way it is very easy to use an electrical light source and an additional one, the mentioned parts of the device position optical device works with several lenses. 55 to be arranged correctly in the tubes, it is "a problem. This not only requires more effort, screws or even the creation of a stand, but the entire facility is also not easy to handle outside the tube for any instrument, because two It is particularly advantageous if this is necessary, and a level bearing cross must also be formed by a cross slot in a disc that is transparent to light underneath the tube for the optical instrument.
