To all whom it may concern:
Be it known that I, David E. Goe, a citizen of the United States, residing at Madison, in the county of Dane and State of Wisconsin, have invented a certain new and useful Improvement in Safety-Razors, of which the following is a specification.
My invention relates to safety razor blades and mechanism for holding the blade while in use. Its object is to make such a razor and handle or holder which can be cheaply manufactured, which will be accurate and efficient in operation, not readily liable to get out of order, and which can be easily cleaned and repaired.
My invention consists in a novel form of blade, having a ridge or corrugation running lengthwise of it, adapted to engage a corresponding surface in the holder, whereby the blade itself is given greater rigidity and when once placed in position in the holder can always be re-inserted in substantially the same position; in a novel form of handle or holder adapted to have the blade mounted therein for the purpose of use and in a novel form of guard for the blade whereby the edges of the blade are supported without being in contact with the guard.
My invention also consists in many details of construction which will be hereafter more fully described and claimed.
Referring to the drawings;
Again referring to the drawings, I provide as the most valuable feature of my invention a safety razor blade
Rotatably mounted upon the upper portion
In the operation of the device, the user rotates the handle
I do not wish to be understood as limiting myself to exact details of construction, which may be varied within reasonable limits without departing from the broad principle of my invention.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is;
1. In a safety razor the combination of a thin blade formed with a longitudinal arch, groove, or corrugation, a guard plate or table constituting a part of the main frame upon which said blade rests provided with an arch, groove, projection or the like registering with the corresponding part upon the blade to position and hold it, and means to clamp the parts together.
2. In a safety razor the combination of a thin blade formed with a longitudinal arch projection groove or corrugation, a guard plate or table constituting a part of the main frame upon which said blade rests provided with an arch, projection, groove or corrugation, registering with a corresponding part upon the blade to position and hold it in place manually adjustable means to clamp and hold the blade and guard plate firmly together.
3. In a safety razor the combination of a thin blade formed with a longitudinal arch projection groove or corrugation, a guard late or table constituting a part of the main frame upon which said blade rests provided with an arch projection groove or corrugation registering with a corresponding part on the blade to position and hold it in place means for detachably holding said blade upon the guard plate or table, and means for adjustably controlling the blade holding means.
4. In mechanism of the class described, the combination of a handle, a blade table or head supporting a razor blade, a mechanism for moving said blade table to and from said handle, a rectangular member rotatably mounted upon said handle, having its upper bar fitting over said head and a blade mounted upon said holding device or head under the upper bar of said rectangular member, substantially as described.
5. In mechanism of the class described, the combination of a handle, a blade table mounted over said handle, a shank upon one of said members threaded into the other whereby rotating one with reference to the other will cause said blade table or head and handle to be moved toward or from each other, a rectangular member easily rotatably mounted upon said handle and fitting over said head, and a blade mounted upon said blade table under a portion of said rectangular member whereby moving the head and handle away from each other, clamps the blade upon the blade table under the upper bar of the rectangular member substantially as described.
In witness whereof, I have hereunto subscribed my name in the presence of two witnesses.
David E. Goe.
