    Abstract: 1299. Stewart, W. H. Jan. 19. Conductors.-Relates to a method of supporting overhead conductors so that in case the conductor breaks the broken wires becomes dead. The Figure is a sectional view of the supporting-device. When the conductor D breaks, the part A which is soldered to it slips out of the bevelled-shaped case B and becomes suspended and insulated by the cord C. As the part A slips out, the projection I knocks the rotatable piece G, thus pressing it against the projection E and preventing the other piece from being liberated. It is stated that the piece G may be held, after being moved to one side, by means of a'suitably-placed spring.
