Abstract
Abstract Two symmetrically arranged pairs of rollers support the rotating surface of a rotary furnace, and each pair of rollers is supported on the respective ends of a beam. The beam is pivoted about an axis parallel to the axes of the rollers on a bearing with a cylindrical gliding surface whose axis is perpendicular to the plane passing through the axis of the rotating surface of the furnace and the pivoting axis of the beam. A support for the bearing has a cylindrical gliding surface complementary to the gliding surface of the bearing.

Claim 1
Independent Claim
216 words
In a cylindrical rotary furnace having a surface rotating about an axis, support means for the rotating surface comprising 1. two symmetrically arranged pairs of rollers supporting the rotating surface of the furnace, a. the rollers having axes parallel to each other; 2. a beam having two ends, a. one roller of each pair of rollers being supported on each one of the beam ends; 3. a pivot means supporting the beam for pivoting about a first axis parallel to the axes of the rollers and about a second axis perpendicular to a plane passing through the axis of the rotating surface and the first axis, the pivot means including a. two pivots each having a cylindrical gliding surface and the gliding surfaces having a common axis constituted by the first axis, b. two bearing blocks each supporting a respective one of the pivots for pivoting the beam the first axis, c. a cross bar interconnecting the bearing blocks, with the respective bearing blocks mounted at the end of the cross bar on respective sides of the median plane of the cross bar perpendicular to the roller axes, and d. a support for the bearing blocks, the bearing blocks and the support having complementary cylindrical gliding surfaces having a pivoting Axis constituted by the second axis.
