device for guiding and mounting a stirring axis for laboratory glass apparatus and technique

摘要

There is provided an apparatus for guiding and seating a stirrer shaft for laboratory or industrial glass apparatus which consists of bearings and abutments and makes possible a change in the angle of slope of the stirrer shaft axis in the apparatus, wherein the bearing consists of a smooth disc with a concentrically arranged, spherical recess at whose deepest position there is arranged a conical bore breaking through the disc, and a body with a spherical surface and a central, axial bore which is rotatably fitted in the spherical recess of the smooth disc, whereby the stirrer shaft can be so affixed in the bore of the body, that it projects through the bore in the disc and has a stop in the abutment.
