Abstract

Abstract An electromagnetic motor and generator is disclosed having a pair of solenoids wound on a cylinder, each of said solenoids comprising three separate but connected windings. A magnetizable piston is positioned for reciprocation in the cylinder and is connected to a rotatably mounted crankshaft. A commutator connected to the crankshaft and interposed in an electric circuit selectively energizes the solenoids to cause rotary motion of the crankshaft. An additional circuit means is also provided for recapturing electrical energy generated in each of the solenoids upon deenergization of the solenoid by said switch.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 99 words
A motor-generator comprising: a. a cylinder having a pair of solenoid means disposed one around each end thereof and a magnetizable piston reciprocally mounted in said cylinder, said piston being swingably connected by link means to a rotatably mounted crankshaft means; b. switch means operatively connected to said crankshaft means and interposed in an electric circuit for selectively energizing said solenoids to cause rotary motion of said crankshaft means; and c. additional circuit means connected to each of said solenoids for recapturing electrical energy generated in each of said solenoids, upon deenergization of said solenoids by said switch means.
Claim 2
Dependent Claim 99 words
A motor-generator comprising: a. a cylinder having a pair of solenoid means disposed one around each end thereof and a magnetizable piston reciprocally mounted in said cylinder, said piston being swingably connected by link means to a rotatably mounted crankshaft means; b. switch means operatively connected to said crankshaft means and interposed in an electric circuit for selectively energizing said solenoids to cause rotary motion of said crankshaft means; and c. additional circuit means connected to each of said solenoids for recapturing electrical energy generated in each of said solenoids, upon deenergization of said solenoids by said switch means.
Claim 3
Dependent Claim 38 words
A motor-generator as set forth in claim 1 wherein said additional circuit means comprises diode means serially connected with a load means and said serially connected diode and load means being connected in parallel across said solenoid means.
Claim 4
Dependent Claim 21 words
A motor-generator as set forth in claim 1 wherein each of said solenoid means comprises first, second and third winding means.
Claim 5
Dependent Claim 77 words
A motor-generator as set forth in claim 3 wherein said first winding means of each of said solenoid means extends from an end of said cylinder to the approximate midpoint thereof, said second winding means of each of said solenoid means is substantially co-extensive with and over said first winding means and said third winding means extends over said second winding means from an end of said cylinder to the approximate midpoint of said second winding means.
Claim 6
Dependent Claim 30 words
A motor-generator as set forth in claim 4 wherein said first and second winding means are connected in parallel with each other and in series with said third winding means.
Claim 7
Dependent Claim 24 words
