Abstract

21,797. Johansson, F. J. E. Sept. 20. Water-tube boilers; headers. - The separate parts of divided headers or the end boxes of water-tube boilers are joined by a bolt passing through abutting flanged off-sets, which are so formed that the spring action of the material under steam pressure tightens the joints. The invention is shown applied to a water-tube boiler in which the tubes are traversed by smoke-tubes. The double tubes 1, 2 are secured to end boxes 3, of which adjacent ends are formed with bearing-surfaces 4, preferably directed inwards. A headed bolt 5 passing inside the flanges 4 bears on the opposite walls of the adjacent projecting parts 8, 9, and is fastened by a nut 7. The tubes 1, 2 may be corrugated.
