The division of the overhead wires into sections shouldnot require the employment of insulating connectors, whichare subject to great deterioration on account of the high ten-sion employed. The mount of the collecting stem is attached in place by boltswhich permit its ready renewal in case of need. Spiral Springs are arranged so as to cause the stem to pressfirmly against the overhead conductor and insure a good con-tad thereon in any position in which it may he rotated.
