The crown sheet is flat andsupported by crown stays, and thereare also horizontal stays between theoutside firebox sheets above the crownsheet. There are four stays betweenthe tube sheets, which are fitted withturn buckles for adjustment Themethod of fastening the front tube sheetto the boiler shell is interesting. Theflange of this sheet is turned out-wards, and to it is fastened the smoke-box sheets. The fastening betweenthe boiler shell, which is of smallerdiameter than the smo
