Amphibious dirigible airships
First Claim
1. A semi-rigid dirigible airship comprising an envelope for containing lifting gas (lighter-than-air), said envelope having a bow which is curved in vertical section for reduction of drag, having a metal bow plate on the bow, the stern of the airship being curved in vertical section for strength but on a shorter radius than that of the bow, a metal stern plate on said stern, an elevator pivotally connected to said stern metal plate, the axis of pivotal connection being substantially horizontal, a plurality of metal ribs attached to the bow plate and connected to the stern plate and extending fore and aft both on the top and on the bottom of the airship and secured to the envelope all along their lengths on top and bottom, said airship having a vertical rudder for steering starboard and port, propulsion means for said airship, at least one ballonet in said envelope to take in and exhaust air to keep the pressure up and not too great, a pair of separate cars one on either side of the airship underneath, cords inside said envelope extending from and attached to the upper part of the airship and attached to the cars for the support thereof, the cars being floatable for landing the airship on water, at least one car having a water ballast compartment, a scoop at the forward end of such car to take in water to the ballast compartment, and a valve to discharge the water.

Abstract
A lighter than air ship, with a bow plate on the bow, two cars suspended beneath the elongated bag, the cars having water ballast tanks, with scoops to take in water when the airship is landing on water and valves to let the water out when the airship is taking off, with a sea anchor and rode (rope) to the bow plate, a ground (bottom) anchor and rode (rope) to the bow plate, metal ribs attached to the bow plate and extending to a stern plate and connected to the bag both above and below the bag, with a vertical rudder for steering right and left, horizontal rudders for steering up and down and a ballonet inside the bag for keeping proper pressure, landing wheels for landing the airship on land, the cars being capable of landing the airship on water, the bag having an aerodynamic lifting shape so that the airship can take off and fly heavy and by dumping water can land safey and landing on water can take in water to be stable on the surface, can land on land with the wheels and be secured by the rodes.

- 1. A semi-rigid dirigible airship comprising an envelope for containing lifting gas (lighter-than-air), said envelope having a bow which is curved in vertical section for reduction of drag, having a metal bow plate on the bow, the stern of the airship being curved in vertical section for strength but on a shorter radius than that of the bow, a metal stern plate on said stern, an elevator pivotally connected to said stern metal plate, the axis of pivotal connection being substantially horizontal, a plurality of metal ribs attached to the bow plate and connected to the stern plate and extending fore and aft both on the top and on the bottom of the airship and secured to the envelope all along their lengths on top and bottom, said airship having a vertical rudder for steering starboard and port, propulsion means for said airship, at least one ballonet in said envelope to take in and exhaust air to keep the pressure up and not too great, a pair of separate cars one on either side of the airship underneath, cords inside said envelope extending from and attached to the upper part of the airship and attached to the cars for the support thereof, the cars being floatable for landing the airship on water, at least one car having a water ballast compartment, a scoop at the forward end of such car to take in water to the ballast compartment, and a valve to discharge the water.
- 15. An amphibious dirigible airship comprising an elongated bag containing gas lighter than air, said bag having a bow, rudders to direct said airship to starboard, to port, up and down, an air ballonet in said bag to keep said bag inflated and to prevent the pressure from rising too high despite changes in altitude of the airship, a bow plate on and secured to said bow, a sea anchor for said airship, a rode for and attached to said sea anchor, a ground anchor for said airship to be held to the bottom of a body of water, a rode for and attached to the ground anchor, a ring having an orifice for passage of the sea anchor rode therethrough, said ring being mounted to the bow plate, a ring having an orifice for passage of the ground anchor rode therethrough, said ring being mounted to the bow plate, a car secured to the bag and below it, means to belay said rodes so that they will not run through the rings, a water chamber in the bottom of said car, a water scoop near the bottom of the car to collect water for the water chamber when the car is on the surface of a body of water, a valve in the bottom of the chamber to let the water out and to keep it in, means in the car to operate the valve, a wheel well in the bottom of said car, a wheel for landing the moving airship on a runway, and apparatus for raising the wheel into the wheel well and for lowering it for landing.
