ABSTRACT:
An apparatus including two automobile tires one mounted above the other with the treads in contact and counterrotating so as to pull a length of electric cable through the line of contact between the tires; a system of sprockets and chains to drive the two tires at the same speed, a system of gears to provide selection of several different rotational speeds of the tires; a housing for each tire, input shafts on the gear system to permit attachment by an electric hand drill to drive the apparatus; the two housings being connected by pivot pins permitting the housings to be opened and closed like a jaw, the pivot pins being readily removable to permit the two housings and their tires to be separated entirely from each other; and a releasable clamp to press the two tires against each other with an adjustable force.
