To all whom it may concern:
Be it known that I, Phillip Iroff, a citizen of Russia, residing at Brooklyn, New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Safety Razors, of which the following is a specification.
This invention relates to safety razors, having particular reference to the construction of the cutting blade and the means for securing the same upon the guard or holder.
The invention has for an object to provide a novel form of reversable blade, and to combine therewith a new and easily manipulated securing means.
A further general object is to provide a cutting blade capable of the most extensive use without, re-sharpening.
For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.
As here shown my improved safety razor comprises a holder in the form of the plate
Toward its centre the holder plate
The cutting blade
The blade
To secure the blade
The latches
In the use of my improved safety razor, as will be apparent, the blade
Each blade is capable of use on all four edges and may be reversed on the holder by removing it and springing it with the hands, the other pair of the flanges
Having thus described my invention what I claim as new and desire to protect by Letters Patent of the United States is as follows:
1. A safety razor comprising a polygonal holder plate presenting a convexed surface, and a complementary blade arched to engage said convexed surface and capable of being sprung to have either face constitute the exterior of the arch, a cover and devices projecting inwardly from the cover adapted to be engaged by locking means on the holder plate.
2. A safety razor comprising a polygonal holder plate presenting a convexed surface, and a complementary blade arched to engage said convexed surface and capable of being sprung to have either face constitute the exterior of the arch, pivoted latches on the holder plate, a cover plate and a pair of flanges projecting from the cover plate and having apertures adapted to receive the said latches.
3. In a safety razor, a holder plate, a handle fixed thereto, a cover plate, and locking means for said plate having an operating element extending rearwardly through said handle, said locking means comprising a pair of pivoted latches, and toggle links connected to said latches and said operating element.
4. In a safety razor, a convexed holder plate having a recessed intermediate portion and a central aperture, a neck-flange projecting forwardly from said plate and surrounding said aperture, and means confined within said neck-flange and adapted to be projected laterally therethrough into the said recessed portion for securing a blade to the holder.
5. In a safety razor, a holder plate of shallow pyramidal form having a recessed intermediate portion and a square central aperture, a neck flange projecting forwardly from said plate and surrounding said aperture, a tubular handle secured to and projecting rearwardly from said plate, a rod slidable in said handle and having a head projecting from the rear end of the latter, a pair of toggle links to which the forward end of said rod is connected, and a pair of hooked latches to which the said toggle links are attached at opposite ends, said latches being adapted to be withdrawn within the confines of the said neck flange, the latter presenting apertures to receive the hooks on the said latches.
6. A blade for safety razors presenting cutting edges on all sides thereof and arched from all sides toward the centre, said blade having a square central aperture, and pairs of oppositely projecting flanges at the sides of said aperture.
7. A blade for safety razors presenting cutting edges on all sides thereof and arched from all sides toward the centre, said blade having a square central aperture, and pairs of oppositely projecting flanges at the sides of said aperture, said blade having slots extending diagonally outward from the corners of the said aperture.
In testimony whereof I have affixed my signature.
Phillip Iroff.
