  • Patent number: 6921315
    Abstract: An integral pump assembly may be used to power a toy vehicle. The pump pressurizes fluid stored within the pressure vessel. The pressurized fluid within the pressure vessel drives the engine that powers the toy vehicle until the stored pressurized fluid has been depleted. The pump may then repressurize the pressure vessel to again drive the pneumatic engine. The pump is substantially disposed within the body of the toy vehicle.

  • Patent number: 6280284
    Abstract: A toy submarine consisting of three components. Two of the components are an injection molded thermoplastic and the other is an ordinary rubber band. The plastic is slightly positively buoyant in typical tap water. The first molded component is the tailpiece and it includes a generally cylindrical body with an integrated propeller. The second molded component is the headpiece and it includes a generally cylindrical body with an integrated propeller that spirals in the opposite direction of the tailpiece propeller. Together they form a counter rotating propeller system. The bodies of both the tailpiece and the headpiece are hollow and open at both ends. One end of the tailpiece's body mates with one end of the headpiece's body such that their axes are aligned and the bodies are able to easily rotate relative to each other. The other ends of the tailpiece and headpiece each have a longitudinal slot.

  • Patent number: 6093076
    Abstract: A water propelled toy torpedo including a main housing having an open forward end and an open rearward end. A battery pack is disposed within the main housing inwardly of the open forward end. A battery cap is disposed within the open forward end of the housing in communication with the battery pack. A forward portion has a micro switch extending forwardly therefrom. A motor is disposed within the open rearward end of the main housing. The motor is in communication with the battery cap. The motor has a shaft extending rearwardly therefrom whereby an outer end of the shaft is disposed outwardly with respect to the open rearward end of the main housing. A transparent cap portion couples with the open forward end of the main housing. The cap portion has an open inner end and a closed arcuate outer end. The arcuate outer end has a post extending inwardly from an inner surface thereof. An inner end of the post selectively contacts the micro switch of the battery cap to facilitate activation of the torpedo.

  • Patent number: 4919637
    Abstract: A model submarine has an inherent "fail safe" feature, so that the submarine (if submerged) will rise to its periscope depth in the event the submarine encounters a stationary object, or in the event a power failure occurs. Power is supplied by a single submersible motor-pump unit within a free-flooding hull. The motor-pump unit supplies a pressurized water discharge for, first, forward propulsion of the submarine via the discharge nozzle of an ejector pump; and second, for hydraulic control of the diving and steering maneuvers. The ejector pump has a venturi for aspirating fluid out of the ballast tank. An automatic depth control feature assures that the submarine will level off to a desired predetermined depth when a diving command signal is given; and the desired predetermined depth is adjustable.

  • Patent number: 4879833
    Abstract: A shark diverting apparatus is set forth wherein a self-propelled torpedo-like device is arranged with a self-contained power source including a signal generator for generating a signal for attracting sharks. A flotation collar is fixedly secured about a central diameter of the torpedo-like body and includes a self-inflating canister and a manually operable stem for inflating the collar to a larger size. An included value slowly releases air pressure from within the collar during the travel of the device wherein subsequent to a timer circuit activation, a signal generator is activated for attracting sharks while simultaneously air pressure is released from the flotation collar to draw sharks away from and below an individual.

  • Patent number: 4826465
    Abstract: A diving model submarine utilizes an automatic depth level control mechanism, water jet propulsion, a water powered aspirator for ballast tank evacuation, hydraulic control of steering, diving plane attitude, and ballast tank valve action. The model diving submarine is controlled by radio signals and fires torpedos.

  • Patent number: 4673370
    Abstract: Pontoons along both sides of the vehicle can be filled with either air or water, at the user's preference. When the pontoons are filled with air the vehicle floats in water and is driven along the water surface by a propeller and also by a tread drive. When the pontoons are filled with water the vehicle sinks in water and is driven along the bottom by, again, the propeller and treads. In either event when the vehicle comes to a dry surface it continues to be driven along that surface by the treads. The pontoons are provided with a hole and plug for use in filling or draining them. Preferably the interior spaces of the pontoons communicate through a cross-connection chamber that rougly equalizes the amount of water in the two pontoons, so that the vehicle has minimal tendency to capsize or ride in the water at a cant. An unusual two-worm-and-worm-gear drive train provides power to the tread drivers both fore and aft with high mechanical advantage and very few moving parts.
