The band, F, which is put around the middle, is put on hot,and becomes tight by contracting as it cools. The center of thespring has a hole drilled through it with a pin, s, fig. 294 (whichshows a cross section of a spring), to prevent the plates fromsliding endwise. The plates at each end usually have a depression, (7, fig. 296 (which is a cross section of a plate on a largerscale than the preceding figure), made in them on one side, anda corresponding elevation, b, on the other. The elevation onone plate fits into the depression on the other, and thus preventsthe plates from slipping sideways. Fig. Fig. 290.
