Laying out for boiler makers and sheet metal workers; a practical treatise on the layout of boilers, stacks, tanks, pipes, elbows, and miscellaneous sheet metal work . Fig. 21 Plate and Filled with Asbestos Rope Packing. METHODS OF FASTENING DIRECT ST.\ Fig. 23 British Columbia rule:125 X 81 = 281 pounds pressure. 36 It will be understood that while there is a difference in thepressure it only applies to the plate. However, the BritishColumbia rule would permit of a larger stay, and this wouldthen allow greater pressure, while the United States rule willnot allow a larger stay, as the plate is the weaker, and nothingwould be gained by increasing the size of the stay. Figs. 20 to 27 inclusive, show four different ways of fasteningthe braces to the plate. Fig. 21 shows screwed stays rivetedover as just worked out in the preceding examples. Figs. 22 and 23 show the stay screwed into the plate with anut on the outside. This nut assists in supporting the plate,so a different constant may be used than with Fig. 21. be that part where the stays are spaced with the greatest order for the plates to withstand the pressure a doublingplate is applied, which increases the thickness of the heads atthat : Figs. 20 and 21â
