"Certain of my improvements consist in combination, with a marine torpedo and an electric circuit, of a pin or bar adapted to complete said circuit and effect the firing of the torpedo; also, in the combination, with a marine torpedo and an electric circuit, of two resistance coils controlling the firing of a cartridge, one being adapted to be cut out by the contact of a firing pin at the bow of the torpedo with any object, and the other being adapted to be cut out by the operator at will. Other improvements consist in the combination, with the exhaust pipe of the propelling engine, of a hollow propeller shaft whereby the motive agent may be exhausted into the water in the rear of the torpedo. Other improvements consist of a novel cable reel or drum composed of parts capable of being readily detached and attached."
