To all whom it may concern:
Be it known that I, Osroe A. CLark, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Safety-Razors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification.
This invention relates to a safety razor which embodies a handle that grasps the guard and a clamping plate, between these two latter being installed the blade having a multiplicity of edges in register with a multiplicity of edges on the guard so that the handle acts to hold the blade in place without perforating the blade. When a blade is perforated, as is necessary in a number of makes of razors, the thin blades are cracked when they are tempered, and there is a considerable loss and waste of material under these conditions.
The herein described razor comprises a handle with spring arms to bear over on the corners of the clamping plate, or on the blade, and having a central element to be projected up against the under side of the guard which is under the blade, and thus act to draw the parts tightly together.
A still further object of the invention is to provide a razor, the edges of which will give different degrees of shaves, that is one edge will give a medium shave, another edge a close shave, and still another edge might be made so that it gives a very close shave. The closeness of the shave is regulated according to the difference in the distances between the blade and the guard, and in order to bring the differences about the guard underneath the cutting edge of the blade is cut away for different distances, or not at all, so that the different edges will give different shaves.
The invention is illustrated in the accompanying drawing, in which—
The razor comprises a guard
To provide a means for giving different degrees of shaves, that is to make either a close or a medium shave, it is necessary to draw the blade back from the guard various distances. I prefer to vary this distance by withdrawing the guard from the blade, which can be done by bending it down, or it can be done as shown in
In my razor with this multiplicity of edges, I can make one or more edges as in
This razor is cheap to make, is compact and is quickly assembled and taken apart.
Having thus described my invention, what I claim is:—
1. A safety razor comprising a guard having a plane blade holding surface, a blade on the guard, and means for securing the blade and the guard together with their edges parallel, the edges of the guard having their top surfaces cut away to form various spaces between the guard and the edges of the blade.
2. A safety razor comprising a guard having a plane blade holding surface, a blade on the guard, the blade and the guard having e multiplicity of opposite parallel edges, a backing plate, a handle having arms to go over the corners of the backing plate, and adjustable means in the handle for engaging the back of the guard, the edges of the guard being cut away various distances to form various spaces between the guard and the blade.
3. A safety razor comprising a guard having a multiplicity of edges, a blade having edges parallel with the edges of the guard, a backing plate on the blade, the edges of the guard being cut away at various depths to form various spaces between the edges of the guard and the edges of the blade, a handle having spring arms, fingers on the ends of the arms to go over the corners of the backing plate, a stem in screw-threaded relation with the handle and adapted to bear on the back of the guard, and means on the projecting end of the stem for its manual manipulation.
In testimony, that I claim the foregoing, I have hereunto set my hand this 16th day of September 1908.
