Claim 5

A reciprocating device according to claim 2 including connecting rod means coupled between said piston and a U-shaped section of a crank shaft rotatably mounted on said engine block whereby said crank shaft is rotated by the reciprocating motion of said piston.

Claim 6

Claim 8

A reciprocating device according to claim 1 wherein said surface is a circular peripheral surface of said disc member, and said circular peripheral surface is spaced in a close proximity to said bottom opening of said cylinder chamber.

Claim 9

A reciprocating device comprising: a horizontal engine block having at least two vertical cylinder chambers therein; said cylinder chambers having a bottom opening and a top opening respectively; a first piston slidably disposed within one of said cylinder chambers; a second piston slidably disposed in the other cylinder chamber; said first piston and second piston having identical magnetic polarization; first connecting rod means movably coupled to said first piston and to a first U-shaped section of a crank shaft through said top opening of said first cylinder; said crank shaft being rotatably mounted on the top surface of said engine block; second connecting rod means movably coupled to said second piston and to a second U-shaped section of said crank shaft through said top opening of the other cylinder chamber; said crank shaft being configured such that when said first U-shaped section is at a top dead centre position said second U-shaped section is at a bottom dead centre position; biasing means disposed within said cylinder chambers to normally maintain said first piston and said second piston to position immediate to said bottom openings respectively; a disc member rotatably mounted in a spaced relation to the under surface of said engine block; said disc member being rotatable with respect to a central shaft vertically located midway between said vertical cylinder chambers; and said disc member having a planar top surface located in a close proximity to said under surface of said engine block; a plurality of fixed magnetic elements mounted in said disc member over a locus of slightly less than 180 degrees and directly opposite to said bottom openings of said vertical cylinder chambers, said fixed magnetic elements having a magnetic polarization identical to said first piston and second piston whereby said disc member is selectively rotatable to align said fixed magnetic elements with said first piston and second piston alternately to drive said first piston and second piston in complementary reciprocating motion so as to rotate said crank shaft.

Claim 10

A reciprocating device comprising: a horizontal engine block having at least two vertical cylinder chambers therein; said cylinder chambers having a bottom opening and a top opening respectively; a first piston slidably disposed within one of said cylinder chambers; a second piston slidably disposed in the other cylinder chamber; said first piston and second piston having identical magnetic polarization; first connecting rod means movably coupled to said first piston and to a first U-shaped section of a crank shaft through said top opening of said first cylinder; said crank shaft being rotatably mounted on the top surface of said engine block; second connecting rod means movably coupled to said second piston and to a second U-shaped section of said crank shaft through said top opening of the other cylinder chamber; said crank shaft being configured such that when said first U-shaped section is at a top dead centre position said second U-shaped section is at a bottom dead centre position; biasing means disposed within said cylinder chambers to normally maintain said first piston and said second piston to position immediate to said bottom openings respectively; a disc member rotatably mounted in a spaced relation to the under surface of said engine block; said disc member being rotatable with respect to a central shaft vertically located midway between said vertical cylinder chambers; and said disc member having a planar top surface located in a close proximity to said under surface of said engine block; a plurality of fixed magnetic elements mounted in said disc member over a locus of slightly less than 180 degrees and directly opposite to said bottom openings of said vertical cylinder chambers, said fixed magnetic elements having a magnetic polarization identical to said first piston and second piston whereby said disc member is selectively rotatable to align said fixed magnetic elements with said first piston and second piston alternately to drive said first piston and second piston in complementary reciprocating motion so as to rotate said crank shaft.

Claim 11

A reciprocating device according to claim 8 including two permanent magnets mounted in a mounting base mounted in a close spaced relation to the under surface of said disc member and positioned directly opposite to said cylinder chambers, said permanent magnets having an opposite magnetic polarization to the magnetic polarization of the pistons.
