ABSTRACT:
This disclosure teaches a connector for use 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 and has the connector mounted thereon. The distal section (with its hardware intact thereon) is severed from the proximal section. The distal section is then connected to project from the new pole section by inserting and securing the distal section in the connector. The connector includes an annular sleeve engageable about the outside of the new pole section. The sleeve projects beyond the new pole section and has push plates positioned within the sleeve to embrace the distal section to hold it socketed therein. The push plates are engaged by means of bolts anchored in the sleeve. A suitable sealant, such as grout, is also employed.
