Patents by Inventor Lee S. Chadwick, II

Lee S. Chadwick, II has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8056528
    Abstract: A rotary machine which can be either a pump or an internal combustion engine has a housing enclosing a plurality of rotor spindles lying on the surface of an imaginary cone for driving an output shaft positioned at the vertex of the imaginary cone. The spindles have a beveled gear on one end and engaging an output shaft and a conical bearing on the other end. Angled eccentric rotors are mounted to each spindle shaped to maintain tangential sliding contact with two adjacent rotors to form a compression or combustion chamber. A spherical version of a compressor or an engine uses a plurality of rotary pistons each of which is eccentrically mounted and forms a spherical segment. Each rotary piston is mounted for tangential sliding contact with at least two other rotary pistons to form a displacement chamber therebetween. The rotary pistons use a generally “tear drop” shape. A rotary pump has a housing having a manifold for distributing intake and exhaust air.

  • Publication number: 20090068050
    Abstract: A rotary machine including: a housing; a plurality of rotor spindles aligned along three orthogonal axes; rotor blades on the rotor spindles and arranged relative to each other so that each rotor blade is in tangential sliding contact with at least two other rotor blades and forming a plurality of working chambers each having a volume which changes as the rotor spindles rotate; a gear system including a plurality of internal bevel gears on the ends of the plurality of rotor spindles and for synchronizing rotation of the rotor spindles during operation; and a central valve mechanism with the rotor spindles extending radially outward therefrom and around which the rotor blades are arranged, wherein the central valve mechanism controls flow of a fluid to at least some of the working chambers formed by the rotary blades.

  • Patent number: 4492723
    Abstract: A construction kit for forming a variety of curvilinear faced polyhedrons all surfaces of which are arcuate and clusters of such polyhedrons from one or more of a variety of planar foldable polygonal components derived from arcuate lobed equilateral triangles, squares, rhombuses, pentagons and hexagons.
