To all whom it may concern:
Be it known that I, Stuart Speirs, a citizen of the United States, and resident of the borough of Manhattan, city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in a Safety Razor, of which the following is a specification.
This invention relates to a safety razor, Its object is the production of a razor that is particularly adapted for women shaving themselves beneath their arms, although it may be used in a manner similar to that of the ordinary safety razor now in use. A second object of the invention is the production of a razor that can be safely employed to shave hollow or concaved surfaces. A third object of the invention is the production of a razor that will curve a straight blade when located in place in the razor, and which will remain curved when in use.
The organization of the invention comprises a longitudinally convexed blade platform and a longitudinally concaved bending and locking member. A straight blade is detachably connected to the locking member, and when the latter is locked to the platform the blade is longitudinally curved to conform to the adjacent faces of the platform and locking member. Lugs are formed with the platform and also with the locking member to cover the ends of the cutting edge of the blade, to avoid injury when shaving the arm pits of a user or other concaved surfaces.

Various modifications may be made in the invention and the present exemplification is to be taken as illustrative and not limitative thereof.
Having described my invention what I desire to secure by Letters Patent and claim is:
1. In a safety razor the combination of a convex platform curved along its longitudinal axis, a concave bending and locking member curved along its longitudinal axis adapted to be locked to said platform and a blade clamped between the convex face of the platform and concave face of said locking member, said blade locking member provided with a positioning flange on its upper edge and having over hanging gripping lugs to hold the blade in an initially flexed position prior to its locking engagement with the platform.
2. In a safety razor the combination of a blade platform curved along its longitudinal axis, a handle extending from the platform, a blade bending and locking member curved along its longitudinal axis, pivoted to and adapted to be locked with said platform, a blade initially flexed and locked to the locking member, when the latter is unlocked from the said platform and means to lock the locking member to the said platform, said blade being fully flexed when said locking member is locked to said platform and securely held between said elements.
3. In a safety razor the combination of a convex platform, a concave bending and locking member pivoted to said platform, means to detachably lock the locking member to the said platform, over hanging gripping lugs extending from the inner face of the locking member and depressions on the inner face of the platform for seating the gripping lugs when the blade bending and locking member is locked to the platform and a straight blade initially flexed and secured to the locking member by means of said gripping lugs, said blade fully bending to the contour of the adjacent faces of said platform and locking member when the latter elements are locked to each other.
Signed at the borough of Manhattan, city of New York, in the county of New York and State of New York, this 17th day of April, A. D. 1922.
