The results, heclaims, do not correspond to the figures obtained in actualpractice. The author favors compressed air traction. The Lord Fender. The accompanying cuts represent a fender for streetrailway cars which, it is claimed, affords actual protec-tion for life and limb. The framework is constructed. FENDER IN POSITION. of galvanized iron tubing, and galvanized iron wire isused for the tightly drawn network. The tubing forthe frame of the main body of the fender is 1% inchesin diameter,—or stronger, if deemed necessary,—andthat for the side frames is three-quarters of an inchin diameter. The latter are supported by springs whichmaybe changed so that the sides maybe adjusted at anydesired angle. When the fender is released from the dash-board and assumes its position in front of the car, thesides adjust themselves automatically. At the front endof the fender is attached a rubber roller 3 inches in diam-eter,—or larger, if practicable,—which may be made ofpneumatic rubber tubing, of solid rubber or of some kindof light wood covered with rubber. The roller is con-nected by gear with two small substantial iron wheels2>% inches in diameter, having rubber tires or bandsof sufficient width and thickness.
