Q. Does the Bowman Motor Have A Patent?

A.

   If a device had been turned down for a patent there is a record of that. Only the first inventor of the device can hold a patent. I have looked at the hole area of magnetic powered devices in the patent office. With the information that we have put on the internet will make the system unpatentable. But you bet this will be tested by some one.

      I found only one patent that used a kind of magnetic balance. Pull-- Patent 3992132 [Energy Conversion System] Nov 16 1976. This patent is off. And it has most all of the Bowman processes, and is old art, and not patentable. It is electromagnetic, and can run itself, and pull a car. This is the most powerful magnetic powered device ever made. I had a chance to see it but did not get there on time.

    Here are more magnetic power motor patent numbers.

• Worthington 1724446 [Magnetic Motor] 1929 used electric solenoids to move magnets in phase.
• Jines&Jines 3469130 [Means for Shielding and Unshielding Permanent Magnets and Magnetic Motors Using the Same] 1969 used cams to move shields.
• Trecy&Derouin 3703653 [Reciprocating Motor with Motion Conversion Means] 1972 used electric solenoids to move shields has crankshaft.
• Kinnison 3899703 [Permanent Magnet Motion Conversion Means] 1975 uses springs cams electric solenoids.
• Kelly 4179633 [Magnetic wheel drive] 1979  used cams power by a small electric motor.
• H Johnson 4151431 [Permanent Magnet Motor] 1979 rotary type.
• H Johnson 4877983 [Permanent Magnet Motor] 1985 is an improved stator for the 4151431 1979 patent has no shield or stator gaps.
• H  Johnson 5402021 [Magnetic Propulsion System] 1995 interactions of magnetic balancing is on the stator not on the arc magnetism like his 1979&1985 patents.

  There are many more designs of magnetic power motors than this, and each year more are made. I can have a patent search done, so this problem can be closed. I will cost $450 for the search. I believe that this would also find Lee Bowman 's disclosed when he applied for a patent in 1954. This would be a big help for this project, if we could find exactly what Bowman would say. And would forever close the door for some other person trying to patent it.
