White's patent "consists in the combination with the diagonal braces in a truss girder, in the manner shown, of a metal female shoe constructed with two open grooves, one running at right angles to the other, and a male shoe constructed with a narrow central tongue or shoulder on its under side and two lateral lugs, ears or stops....With this simple arrangement in truss girders for bridges, the diagonal braces can be set up by the introduction of wedges between the male and female shoes, without danger of crushing the end of the braces..."
