This invention relates to safety razors for ladies' use in shaving the arm pit.
The ordinary safety razor has a straight cutting edge and therefore is not adapted for shaving a concave contour, as it would be apt to cut or scratch the flesh.
The primary object therefore of the invention is to provide a circular cutting blade adapted to be mounted between a clamping member fitted with a handle, and an overlapping cap having a central post of polygonal form in cross-section, extending through a corresponding opening in the blade that the latter may be held against accidental rotation upon the post.
A further object of the invention is to provide a pair of diametrically opposed guards, which may be integral with the clamping member and overlapping segments of the cutting edge of the blade on opposite sides of the latter,—the purpose being to insure against injury to the person through a shearing cut of the blade adjacent the ends of the cutting segment of the razor blade.
Another feature of the construction consists in forming the cap with an inclined or cone-shaped inner face, whereby upon adjusting the tapped end of the handle upon the post of the cap, the blade is held under tension between the inclined or cone-shaped walls of the cap and the edge of a shoulder formed by a raised circular table on the guard. The blade being thus slightly flexed under tension is securely held against vibration while the off-set formed by the circular table raises the cutting edge slightly above the teeth of the guard that a close shave may be effected.
With the foregoing and other objects in view which will appear as the description proceeds, the invention further resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes may be made in the precise embodiment of the invention herein disclosed without departing from the spirit of the same.
In the drawing accompanying this specification:
Referring now to the reference characters shown upon the drawing:

In the embodiment shown the circular cap plate
By thus deflecting the blade from its initial flat condition, the blade is rigidly held between the clamping members in such manner that its cutting edge is not apt to be distorted through vibration in use. The polygonal-shaped post and corresponding opening in the guard blade and razor blade assist in securing the rigidity of the several parts when assembled and properly adjusted,—the construction avoiding any tendency to accidental rotation of the parts in relation to each other when in use.
In the modification shown in
Cooperating with the guard member shown in

Having thus described my invention, what I claim is:
In a safety razor, a circular crenelated guard member having a central aperture, a raised flat circular table surrounding the aperture and flanges adapted to overlap opposite segments of the cutting edge of a circular razor blade; a circular cap of relatively larger diameter than the table, its under face being cone-shaped, surrounding an integral projecting central screw-threaded post, adapted to extend through the central aperture of the guard member; an undivided circular razor blade, located between the guard and cap members, of relatively larger diameter than the cap member, with a central aperture to receive the post of said cap member, but otherwise imperforate; and a handle tapped to receive the end of the screw-threaded post of the cap member, adapted also to bear against the underside of the guard member, whereby upon screwing said handle on the post of the cap member, the inclined marginal edge of the cap is forced onto the margin of the blade extending beyond the edge of the circular table, thereby deflecting the blade into impinging contact with the raised circular edge of the table to secure its cutting edge against vibration, and to provide a micrometer adjustment of said cutting edge in relation to the crenelated guard member.
