The main fact, however, stands out very prominentlythat the character and amount of the staybolt deflection isquite different in the two boilers. As yet, there is not suffi-cient data accumulated to be able to state definitely as tojust why this is so, and what should be done to the generaldesign of one or both of the boilers to put the least possiblestrain on each. In the matter of the buckling of the sheets caused by the. /(? - /- Delaware & Hudson Locomotive No. 794 witli Rigidly StayedWooten Firebox combined action of sheet expansion and resultant stayboltdeflection, it was found that the buckling w-as greater withthe flexible than with the rigid bolts; but, it must be bornein mind that the deflection was also greater, and a studyof the details shows that the ratio of the buckling of theflexibly stayed to the rigidly stayed was less than the cor-responding ratio of deflection. In other words, given afixed amount of staybolt deflection the buckle put in the sheetwould be less with a flexible than with a rigid sta)bolt. While at work on the rigidly stayed boiler having theWootten firebox an attachment was made in the space juslahead of the No. 5 staybolt. As might have been expected,the actual movement of the sheet was about the same as atthe No. 5 staybolt but there was less buckling. This de-veloped the probability that, in this long and wide fireboxat least, the whole
