Plural edge shaving system

Claim 2

A plural edge structure for use in shaving, including a leading member and a following member, each of said members having the form of a plate bounded by first and second flat faces, and each said member having two intersecting facets that define a straight, sharpened cutting edge thereon parallel to said faces, each said cutting edge being offset outwardly from the center of the member at least about one-third the distance from the center of the member to its said first face so that it is positioned closer to the first than to the second of said faces, each of said facets being inclined with respect to the immediately adjacent face of the blade member and said two facets defining a bisector plane, said leading and following members being permanently affixed together with their respective second faces contiguous and with said cutting edges fixed in position parallel to each other in a plane inclined to said second faces in position to maintain a fixed distance perpendicular to said second faces of less than 0.02 inch between said cutting edge of said leading member and said cutting edge of said following member, a spAn between said cutting edge of said leading member and said cutting edge of said following member in the range of 0.03 inch to 0.08 inch and the angle between the bisector plane of the cutting edge of said following member and said plane containing both edges at a fixed value in the range of 20*-32*.

Claim 3

A structure as claimed in claim 1, said members being spot welded together.

Claim 4

A structure as claimed in claim 1, at least said leading member having passages vicinity of said cutting edges.

Claim 5

A structure as claimed in claim 1, at least one of said members having an edge with a bisecting plane inclined to the second face of the associated member and with said members being affixed with the bisecting planes of said edges inclined to one another and diverging from one another in the direction away from the bodies of said members.

Claim 6

A structure as claimed in claim 1 wherein said members are identical to one another.

Claim 7

A plural edge razor blade structure for use with a conventional razor having cap and guard structure, and blade structure being insertable into said razor between said cap and guard structure and including a leading rigid blade member and a following rigid blade member, said blade members being identical to one another and each of said members having the form of a plate bounded by first and second flat parallel faces, and each member having two intersecting facets that define a straight, sharpened cutting edge thereon parallel to said faces, each said cutting edge being offset outwardly from the member at least about one-third the distance from the center of the member to its said first face so that it is positioned closer to the first than to the second of said faces, each of said facets being inclined with respect to the immediately adjacent face of the blade member and said two facets defining a bisector plane, said leading and following members being permanently affixed together with their respective second faces contiguous and with said cutting edges fixed in position parallel to each other in a plane inclined to said second faces in position to maintain a fixed distance perpendicular to said second faces of less than 0.02 inch between said cutting edge of said leading member and said cutting edge of said following member, a span between said cutting edge of said leading member and said cutting edge of said following member in the range of 0.03 inch to 0.08 inch and the angle between the bisector plane of the cutting edge of said following member and said plane containing both edges at a fixed value in the range of 20*-32*.

Claim 8

A plural edge razor blade structure for use with a conventional razor having cap and guard structure, and blade structure being insertable into said razor between said cap and guard structure and including a leading rigid blade member and a following rigid blade member, said blade members being identical to one another and each of said members having the form of a plate bounded by first and second flat parallel faces, and each member having two intersecting facets that define a straight, sharpened cutting edge thereon parallel to said faces, each said cutting edge being offset outwardly from the member at least about one-third the distance from the center of the member to its said first face so that it is positioned closer to the first than to the second of said faces, each of said facets being inclined with respect to the immediately adjacent face of the blade member and said two facets defining a bisector plane, said leading and following members being permanently affixed together with their respective second faces contiguous and with said cutting edges fixed in position parallel to each other in a plane inclined to said second faces in position to maintain a fixed distance perpendicular to said second faces of less than 0.02 inch between said cutting edge of said leading member and said cutting edge of said following member, a span between said cutting edge of said leading member and said cutting edge of said following member in the range of 0.03 inch to 0.08 inch and the angle between the bisector plane of the cutting edge of said following member and said plane containing both edges at a fixed value in the range of 20*-32*.

Claim 9

A structure as claimed in claim 6, each of said members having an edge with a bisecting plane inclined to the second face of the associated member and said members being affixed to one another with the bisecting planes of said edges inclined to one another and diverging from one another in the direction away from the bodies of said members.

Claim 10

A structure as claimed in claim 7, said members being spot welded together.

Claim 11

A structure as claimed in claim 8, each of said members having passages penetrating therethrough for removal of shaving debris from the vicinity of the cutting edge.
