Abstract of Patent No. 5799, granted to C. A. McEvoy, of London, for: "The torpedo is provided with a screw propeller and driving mechanism, and at the same time as the torpedo is set free from the spar the driving mechanism is started. The power for driving the propeller is provided by powerful springs within the torpedo or by an electromotor and a primary battery, the circuit being closed by the act of liberating the torpedo or by compressed air (December 18, 1883).
