Claim 1
Independent Claim
185 words
A razor comprising in combination; a pair of blades, each having a pair of parallel oppositely facing cutting edges therein, each blade spaced apart from the other by a spacer plate held therebetween; a handle member having a pair of spaced apart extensions thereon forming a yoke therebetween; means for fastening said pair of blades and said spacer together as a unit with their blade edges in parallel and having side edges substantially perpendicular thereto; means for swivelably holding said blade unit within said yoke; inwardly facing projections on each arm of the yoke of said handle adapted to mate with dimples formed in the sides of a cartridge member holding said blades and said spacer in a unitary body, thereby to permit rotational movement of said cartridge within said yoke; and stop means on said handle between said extensions to prevent said cartridge from rotating during use of the razor for shaving, said stop means being outwardly moveable between said yoke arms by interconnection with an ejection lever downwardly pivotable from said handle to force said projections out of said dimples in said cartridge.
