Patent for a surface trolley for electric railways that operates "upon the surface of the pavement or ground between the tracks of the road, for connecting the car with the motor power, in place of the trolley and over head wires now suspended upon the unsightly poles in the center or at the sides of the street, which are found to be very objectionable on account of their obstructing the passageway in the streets and upon the side walks, and the wires preventing the free movement of fire companies in extending their ladders in gaining access to buildings, and also because of the great danger attending persons and animals moving about in the street, on account of the charged or live wires frequently being thrown down upon the ground, and coming in contact with and destroying the life of persons, and also on account of the frequent fatal accidents to persons having charge of the repair of the wires and other apparatus in connection with them, often coming in contact with live wires while elevated on the poles and engaged in repairing them" (lines 16-38).
