Stuffing-boxes.-In metallic packing for piston and similar rods, flanged or L-shaped floating rings d, d, Fig. 1, are used to enclose the segmental packing-blocks a, which are embraced by coiled spiral springs c. The ends of these springs are adjustably connected by a block provided with right and left hand threads, or by short lengths of spring c<11>, as shown in Fig. 3, screwing into them. In place of floating rings of L-shape, end floating plates with grooves in which the ends of an annular ring register may be used. In a modification, Fig. 6, the packing-blocks a may be pressed against the rod by radial springs f enclosed by flanged or L -shaped rings g engaging with floating rings d.
