To all whom it may concern:
Be it known that I, Otto Kampfe, a citizen of the United States, residing in the borough of Brooklyn, in the county of Kings, city and State of New York, have invented an Improvement in Safety-Razor Blades, of which the following is a specification.
Safety razors are commonly provided with blades of thin flexible steel in sets of a dozen more or less. Many of these blades are normally flat and are securely held in a suitable holder for use in said flat condition. Other of these blades while normally flat are secured in the holder for use in which the blade is transversely bent or flexed but with a straight cutting edge. Other of these normally flat blades have also been employed in a holder in which the blade is held transversely flat but longitudinally bent or flexed so as to present a curved cutting edge to the face, which is believed to be more advantageous for use than a straight edge.
My invention relates to a flexible safety razor blade normally flat, strengthened along one edge, adapted to be held in its normally flat condition for stropping or honing and yet adapted to be longitudinally bent and flexed so as to present a curved cutting edge to the face in shaving.
In carrying out my invention I provide a thin normally flat sheet steel blade sharpened along one of its longer edges and I secure thereto along the opposite edge and in any suitable of desired manner, a frame of suitable material of flattened
In the drawing,
The blade of my improvement is adapted for use in the holder shown in my application for Letters, Patent filed December 9, 1909, Serial #533,998, and the same might be used in the holder shown in my application filed July 20, 1907, Serial #384,798, and might be adapted for use in a frame of different construction so long as the said frame is made with a curved guard comb and devices at the opposite edges for grasping the blade because with the blade of my present invention the same is longitudinally bent or flexed as inserted in the holder so that when in the holder the cutting edge is curved toward the face in shaving.
In the modification shown in
In view of the normally flat condition of the thin flexible blades of my invention, they are preëminently adapted for grinding, honing or stropping so as to maintain a sharpened edge for use.
I claim as my invention:
1. As a new article of manufacture, a thin flexible steel blade for a safety razor, sharpened along one longitudinal edge and_provided with a yieldable reinforcing frame along its opposite unsharpened edge of
2. As a new article of manufacture, a thin flexible blade of steel for a safety razor, comprising a rectangular form of steel sharpened along one longitudinal edge and unsharpened along the opposite edge and a flattened yieldabble reinforcing
3. As a new article of manufacture, a thin flexible blade of steel for a safety razor, comprising a rectangular form of steel sharpened along one longitudinal edge and unsharpened along the opposite edge, and a flattened
4. As a new article of manufacture, a thin normally flat steel blade for a safety razor, sharpened along one of its longest edges and a yieldable reinforcing frame secured to the said blade along the edge opposite to the sharpened edge and normally flat, and both blade and frame adapted to bend or flex for use when inserted in a suitable holder.
5. As a new article of manufacture, a thin normally flat steel blade for a safety razor, sharpened along one of its longest edges and an open-work frame of spring sheet metal also normally flat and secured to the said blade along the edge opposite to the sharpened edge and both blade and frame adapted to bend or flex when inserted in a suitable holder.
