Abstract: A breakaway transformer base for a lighting pole includes four upstanding corner members (preferably formed of aluminum castings), and four side sheets. Each side sheet is attached to two of the corner members, e.g., by welds or fasteners, thereby interconnecting the corner members. Each corner member forms bolt holes for enabling the base to be bolted to a lighting standard and to an anchored foundation.

Abstract: A frame for reinforcing a handhole of a round metallic utility pole, includes a generally elliptical body defining a major axis and a minor axis and forming a generally elliptical outer periphery, and a generally elliptical inner periphery bordering an opening extending through front and back sides of the body, the opening defining a center axis of the frame. A flange is formed integrally with the body and projects forwardly therefrom at a location spaced inwardly from the outer periphery, wherein the flange is separated from the outer periphery by a forwardly facing shoulder surface of the body. The flange includes an outer flank facing outwardly and intersecting the shoulder surface, wherein the flange outer flank forms an oblique angle with the center axis as seen in a sectional view taken along the major axis, and lies substantially parallel to the center axis as seen in a sectional view taken along the minor axis.

Abstract: A pole vibration damping means includes an annular housing with internal radial pole encircling chambers in which lead spheres are provided for effecting damping of first mode harmonic vibrations with the assembly being attached to the upper end portion of the pole and operating in conjunction with a pole vibration damping device mounted medially for damping second harmonic mode vibrations.

Abstract: A hollow pole having a flared lower end is matingly mounted in a base flange fitted over, and in facing contact with, the flared end portion of the pole and having a tubular wedge matingly fitted in the flared end of the pole so that the pole is bonded to the tubular wedge and the base flange solely by galling action. The assembly is effected by using relatively soft aluminum alloy from which the components are made but which is heat treated prior to assembly to increase hardness and tensile strength so that assembly of the pole, tubular wedge and base flange results in a galling action providing the sole bonding of the pole to the other parts.
