Abstract


"This invention has for objects to enable a submarine vessel, torpedo-mine, or the like, hereinafter called a "submarine vessel" to automatically maintain a horizontal position or state of equilibrium when desired, whether it be at rest or in motion, not withstanding the displacement of the weights within the vessel such as would otherwise interfere with the stability of the vessel, to enable such vessel to be raised or lowered to any required depth on an even keel (or with its axis horizontal,) and to enable it to automatically rise on reaching a greater depth than is desired.

According to this invention we employ the pressure of the water in which the vessel is submerged, and which varies with the depth of submersion, to act through suitable apparatus for obtaining the objects hereinbefore mentioned…"
