Magnetically actuated reciprocating engine

Claim 1

In combination with a crankshaft, a flywheel connected to said crankshaft, a connecting rod pivotally connected to said crankshaft, a piston pivotally connected to said connecting rod, an engine block that rotatably supports said crankshaft and flywheel, said engine block having a cylinder therein in which said piston reciprocates when said crankshaft and flywheel rotate, a source of electric energy, a magnetically actuated device for driving said crankshaft, said device including: a. a housing mounted on said block, with the interior of said housing in communication with said cylinder; b. first and second permanent magnetic means situated in said housing that define an annulus shaped space therebetween that has a magnetic field therein, with the adjacent portions of said first and second magnetic means of the same polarity, and said annulus shaped space axially aligned with said cylinder; c. a solenoid coil that may reciprocate in said annulus shaped space to positions thereabove and below, said solenoid coil having a first end that first enters said annulus shaped space when said solenoid coil moves downwardly relative thereto and a second end that first enters said annulus shaped space when said solenoid coil moves upwardly relative to said annulus shaped space; d. first means that supports said solenoid coil at a fixed position relative to said piston; and e. commutation means for intermittently completing an electric circuit to said solenoid from said source of energy and reversing the direction of flow of current through said solenoid, said commutation means as said crankshaft and flywheel rotate to dispose said second end of said solenoid in a position to move into said annulus shaped space completing an electric circuit from said source of electric energy to said solenoid coil that imparts a magnetic polarity to said second end such that said solenoid tends to be pulled downwardly towards a locked position in said annulus shaped space, said commutation means just prior to said solenoid coil moving to said locked position breaking said electric circuit, said solenoid coil after said electric circuit has been broken continuing to move downwardly in said annulus shaped space due to momentum imparted to said flywheel, said solenoid coil after said first end thereof has moved downwardly in said annulus shaped space below the center of said magnetic field having said electric circuit thereto again completed to energize said solenoid coil for said first end thereof to have a polarity that tends to force said solenoid coil downwardly out of said annulus shaped space, said electric circuit to said solenoid coil being broken by said commutation means when said first end of said solenoid coil has moved downwardly out of said annulus shaped space, with the momentum imparted to said flywheel causing said crankshaft to rotate until said solenoid coil starts to move upwardly towards said annulus shaped space, and said commutation means intermittently completing said electric circuit in reverse order and with reverse current flow as said solenoid moves upwardly through said annulus shaped space.
