The exact location of the cross-tie would depend on thesize of the boiler, the amount of expansion, etc. The totalexpansion and contraction would have to be taken care of bythe bending back and forth of this sheet; on the average sizeboiler about H inch would be required. The cross-tie wouldbe located ^ inch back from the vertical line, so that whenthe boiler is headed up and in working condition, the lugs onthe mud ring would be ;4 inch back from the cross-tie, or theexpansion would be about central with this cross-tie. The locomotive frames at -the strongest are very flexibleand flimsy sidewise, and for this reason they are tied togetherwith numerous cross-ties, waste sheets, etc. Throughout thewhole construction, however, a certain amount of expansionmust be provided for. Fig. 142 shows a waste sheet. There is one or more of thesesheets on nearly every boiler. Th
