Fig. 62.—Quadrated Barb Wire.
Fig. 63.—Iowa Four-pointed Barb Wire.
Of the numerous styles of four-pointed wire, three typical forms are illustrated in [figures 62], [63], and [64].
Fig. 64.—Lyman Barb Wire.
The Glidden patent steel barb wire is made in three styles, as shown in [figures 65], [66], and [67]. [Figure 65] shows the two-point wire, in which, like the others, the barb is twisted around only one of the wires. [Figure 66] shows the “thick-set” which has barbs like the other, but set closer together for such purposes as sheep folds, gardens, or other places, which require extra protection. The four-point barb wire, [figure 67], has barbs of the same form as the two other styles, that is a sharply pricking barb attached to one of the wires of the fence strand, upon which the other wire is twisted, holding the barb firmly in place. The barb is at right angles to the wire, and does not form a hook, but a straight short steel thorn. A sharp point which inflict an instantaneous prick repels an animal more safely than a longer and duller barb.
