To all whom it may concern:
Be it known that I, Edward E. Bennett, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Razor-Blades, of which the following is a specification.
This invention relates to improvements in razors and particularly to improvements in safety razor blades, and the object is first, to provide a razor blade having its corners so formed that they cannot cut or scratch the face of the user, and the object is further to provide a razor blade of permanent concavo-convex form which is so formed that when laid upon a support such as a table, wash stand or the like, the cutting edge of the blade shall be supported out of contact with the table.
In attaining the objects above set forth, I have provided a razor blade provided with a plurality of lugs extending from its cutting edge, said lugs serving not only to prevent the corners of the blade from cutting or scratching the face of the user and preventing injury to the cutting edge when laid down, but these lugs may be employed, if desired, as a means of connecting the blade to a holder.
My invention consists essentially in a rigid inflexible razor blade of permanent concavo-convex form provided with a plurality of lugs extending from its cutting edge, as described in the following specification and particularly pointed out in the appended claim.
Referring to the drawings:
Like numerals refer to like parts throughout the several views of the drawings.
In the drawings, referring now to
Having thus described my invention, what I claim and desire by Letters Patent to seeure is:
As an article of manufacture, a rigid inflexible razor blade of permanent concavo-convex form provided with a cutting edge and having a plurality of lugs extending beyond said cutting edge.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
Edward E. Bennett.
