To all whom it may concern:
Be it known that I, Herbert Augustus Bullard, a citizen of the United States, and a resident of the city and county of San Francisco, State of California, have invented certain new and useful Improvements in Safety-Razors, of which the following is a specification.
My invention relates to safety razors, and has for its object to provide a razor of this class, of improved construction, simple, and economical.
I attain my object by the means illustrated in the accompanying drawings, of which
Similar numerals of reference refer to similar parts throughout the several views, which are all on an enlarged scale.
My invention consists in a general way of the improved holder, the improved blade, and the improved means of securing the blade to the holder.
More particularly, and describing the holder
The holder is by the described construction a spring-box having open ends and two outwardly tending flat springs carrying guards and having a part supporting the blade and having its extremities bent outwardly. The outward pressure of the aforesaid flat springs is received by the longer sides of the aforesaid oblong aperture of the blade, and the outwardly bent portions
Having described my invention what I claim as new and desire to secure by Letters Patent of the United States is—
1. A holder for safety razor blade, comprising a sheet of spring metal shaped to form two outwardly-pressing flat spring members joined at one end to form a finger and thumb hold, said members intermediate their ends bent to form an angular ridge constituting a blade support, guards formed along the apex of each angular ridge, the upper extremities of said spring members curved outwardly and downwardly in opposite directions to each other and constituting blade-securing means.
2. A blade for safety razors comprising a rectangular body having opposite side cutting edges and provided with an oblong aperture, the center of which is nearer one cutting edge than the other and one of which cutting edges is of greater width than the other cutting edge.
3. A safety razor blade comprising a body having opposite cutting edges and provided with an oblong aperture, the center of which is nearer one cutting edge than the other and nearer to one end of the body than to the other.
4. In a safety razor a blade having opposite cutting edges and an oblong aperture the center of which is nearer one cutting edge than the other.
5. A safety razor comprising a holder shaped out of a sheet of spring metal into two outwardly pressing flat springs joined at one end to form a finger and thumb hold, and provided with guards, blade supports and blade-securing means at the other end, in combination with a blade having opposite cutting edges and an oblong aperture the center of which is nearer one edge than the other, and the longer sides whereof are adapted to snugly engage said springs.
In testimony whereof I hereunto sign my name in the presence of two witnesses.
Herbert Augustus Bullard.
