Abstract

636,218. Hollow rollers. LUKENS STEEL CO. May 7, 1947, No. 12311. Convention date, Jan. 10. [Class 34(i)] A heated roller with outer and inner shells defining a peripheral fluid chamber supported at one end by a trunnion has a pipe rotatable with the roller, one end of the pipe opening into the peripheral chamber and the other extending outwardly through the trunnion. The roller comprises two pieces of sheet metal welded along seams 8, 9 to form two concentric cylindrical shells 4, 5 rotatably supported on trunnions 2, 3. One end of the inner shell 4 is welded to an end plate 18 and the other is welded to a plate 11 which is in fluid-tight relationship to the trunnion 2. The outer shell 5 is also welded to the end plate 18 and at its other end is welded to an end plate 17. The end plates 11, 17 are spaced by studs 22. The end plate 17 has a series of pressed out flange portions 23 which engage against the inner plate 11 and are welded thereto to form closed passages 25 which extend to the peripheral chamber 16. The trunnion 2 is provided with an axial bore 26 for the heating fluid which flows through a port 27 to the peripheral chamber. To remove the steam condensate an arcuate tube 28 having one end opening into the peripheral chamber is connected to a tube 32 which extends into the trunnion 2. The tube 28 rotates with the roller and removes any fluid in the lower portion of the chamber or any air in the upper part.
