=1884. Ordinary solid swelled distance rod= with collars, used for compressive strains.

=1885. Similar strut,= but formed of tube with end collars screwed in.

=1886. Double flat-bar cambered strut,= stiffened by distance pieces and bolts.

=1887, 1888, 1889, & 1890. Sections of varieties of the foregoing.=

=1891. Braced strut;= usually of flat bars on edge, riveted together at the intersections.

=1892. Tubular swelled strut,= of plate iron, used for masts, sheer legs, crane jibs, &c.

=1893. Built up strut,= from segmental bars.

=1894. Trussed strut;= the trussing is 90° apart, but may be at any angle; the central bar of course takes the actual thrust, and the truss rods keep it from bending or buckling. See also Nos. 295 to 300, 320.

=Ties,= for tensile strain only are usually of round iron, flat or
other simple section, tube, or even chain, rope, or wire.
