"The object of my invention is to project torpedoes or other similar fulminating projectiles with steam or other mechanical power with great velocity and certainty of direction from any point against any object or vessel which it may be desirable to destroy or remove - such as the works or ships of an enemy, obstructions in channels, and the like. This object I propose to accomplish by fixing the torpedo on the end of an elongating projector so made as to cause the torpedo to travel through a long distance and at a high velocity, while the motive power moves through a short space and with a comparatively slow motion."
