At intervals of 4 c5 in. crown bolts are placedhaving the head inside thffire-box and the nut bearing on a plate on top of thecrown bar. There is also a thimble or ring for eachbolt to pass through, between the top of the crown. Figure 10 THE BOILER 49 sheet and the bottom of the crown bars. These thim-bles maintain the proper distance between the crownsheet and crown bars. The second method of supporting the crown sheetis by the use of radial stays, which are long stay boltsscrewed into the outer shell and into the crown sheet.
