Abstract
Abstract An apparatus having at least two mechanisms for rotary conveyance of treated cylindrical articles through a multisectional furnace and a multisectional cooler. The mechanisms are mounted on frames between sections of the furnace and cooler. Each mechanism has a ring mounted rotatable with respect to its longitudinal axis on two rolls mounted in the frame. The ring longitudinal axis is angularly misaligned with respect to the apparatus longitudinal axis. The article being treated rests on the inner surface of the ring and is rotatively moved forward during rotation of the ring. The mechanisms are provided with means for fixing the ring in the axial direction.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
160 words
An apparatus for heating and cooling long-sized cylindrical parts including a conveyer barrel-type multisectional furnace; a multisectional cooling means mounted coaxially with the longitudinal axis of said multisectional furnace; at least two frames, being installed between a section of said furnace and said cooling means; at least two rolls mounted in each of said frames, at least two mechanisms for rotary conveyance of parts under treatment through said furnace and said cooling means, said mechanisms being mounted on said frames, each of said mechanisms comprising a ring mounted rotatable with respect to its longitudinal axis on said rolls; the longitudinal axis of said ring being angularly misaligned with respect to the apparatus longitudinal axis, said parts under treatment resting on the inner surface of said ring and being rotatively moved forward during rotation of said ring; and means for axial fixing of said ring, said means being provided in each of said mechanisms for rotary conveyance of parts under treatment.
Claim 2
Independent Claim
160 words
An apparatus for heating and cooling long-sized cylindrical parts including a conveyer barrel-type multisectional furnace; a multisectional cooling means mounted coaxially with the longitudinal axis of said multisectional furnace; at least two frames, being installed between a section of said furnace and said cooling means; at least two rolls mounted in each of said frames, at least two mechanisms for rotary conveyance of parts under treatment through said furnace and said cooling means, said mechanisms being mounted on said frames, each of said mechanisms comprising a ring mounted rotatable with respect to its longitudinal axis on said rolls; the longitudinal axis of said ring being angularly misaligned with respect to the apparatus longitudinal axis, said parts under treatment resting on the inner surface of said ring and being rotatively moved forward during rotation of said ring; and means for axial fixing of said ring, said means being provided in each of said mechanisms for rotary conveyance of parts under treatment.
Claim 3
Dependent Claim
51 words
An apparatus as in claim 1 wherein said mechanisms for rotary conveyance of parts under treatment through the apparatus are mounted so that the geometrical centers of said rings are alternatively displaced in the horizontal plane in opposite directions from said apparatus longitudinal axis along the forward travel of treated parts.
