Patents by Inventor Frederick W. Seybold

Frederick W. Seybold 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: 4687427
    Abstract: A rotary internal combustion engine comprising a stationary, water-cooled housing having a large cylindrical bore in which a hollow cylinder with end walls rotates at a uniform speed. On said cylinder a pair of wedge-shaped pistons is mounted diametrically-opposed to a similar pair of reactor elements carried by a multiple-splined shaft, said reactor elements and said pistons forming a combustion chamber whereby a gas and air mixture is compressed prior to ignition; and while expansion is taking place said reactor moves many degrees oppositely to the uniformly rotating piston and thereby increasing the power of the engine.
    Type: Grant
    Filed: April 24, 1986
    Date of Patent: August 18, 1987

  • Patent number: 4057374
    Abstract: A rotary internal combustion engine comprising a stationary, water cooled housing having a large cylindrical bore in which a hollow cylinder with end walls rotates at a uniform speed. On said cylinder a pair of wedge-shaped pistons is mounted diametrically opposed to a similar pair of reactor elements carried by a multiple-splined shaft, said reactor elements and said pistons forming a combustion chamber whereby a gas and air mixture is compressed prior to ignition, whereupon said reactor element moves several degrees oppositely to the uniformly rotating piston while expansion is taking place.

  • Patent number: 3955541
    Abstract: A rotary internal combustion engine comprising a stationary, water cooled housing having a large cylindrical bore in which a hollow cylinder with end walls rotates. On said cylinder a pair of wedge-shaped pistons is mounted diametrically opposed to similar reactor elements carried by a multiple splined shaft, said reactor elements remaining stationary during ignition and expansion and they are then accelerated by a novel crank mechanism to reduce the gap between the pistons and the reactor elements to exhaust the burned gases and/or compress the intake mixture of gas and air before ignition takes place.
