The base is preferably molded of cement concrete with a central hole extending from end to end to receive the pole 1 and its downwardly projecting pointed end 1*. The base is buried in the ground ready to receive the metal pole which is now in- Be it known that I, HARDIN M. HUGHS, a citizen of the United States, residing at Healing Springs, in the county of Benton and State of Arkansasdmve invented a new and useful Base for Poles or Posts, of which the following is a specification.

This invention relates to poles for supporting overhead telegraph, telephone, elecserted in the bore. tric light and other wires and cables; and That portion of the base which is above has for its object to provide a strong and ground is made cylindrical and of a diamerelatively economical metal pole for the purter to enter the downwardly projecting pose set forth, which pole when sunk into flange 5 of a conical cap 6 which covers the the ground, will be firmly upheld by a conbase and protects it from being broken and crete base surrounding the pole with a cap chipped, and assists in supporting the pole covering the same to prevent the same from by means of a sleeve 7 at the apex of the being chipped or broken. The cap has parcover.

The top of the pole 1 is covered by a holscrew coupling 2 in the usual manner. Or

The interior of the cap has a diameter ticular demands of this invention for supgreater than that of the pole and is proporting electric wires of all kinds may be videdtherein with projecting ribs 25 and employed.
