ABSTRACT:
This disclosure teaches a slotted flange connector useable in a method for replacing an existing utility pole (usually wood), without disturbing hardware mounted thereon. As taught in U.S. Pat. No. 3,911,548, the utility pole includes a proximal section having a bottom end attached to the earth and a distal section having hardware mounted thereon. A new pole section (preferably of prestressed concrete) is attached to the earth approximately located and adapted for receiving the distal section. The distal section (with its hardware intact thereon) is severed from the proximal section. The distal section then is connected to project from the new pole section by means of the slotted flange connector disclosed herein. Closure plates complement each other to form a cylindrical enclosure about one of the pole sections. Preferably one of the closure plates is fixed and the other is moveable. The movement preferably is provided by means of bolts. The moveable closure plate has a terminal flange which engages a flange connected to the other pole section. Securing of the moveable plate is by means of bolts through slotted bolt holes.
