To all whom it may concern:
Be it known that I, Philip K. Stern, a citizen of the United States, residing in the city of New York, in the county and State of New York, have invented certain new and useful Improvements in Safety-Razors, of which the following is a specification.
My invention in safety razors relates to certain new and useful improvements in that type of safety razors embodying a flat blade and a guard adapted to the edge of the blade to prevent the latter from accidentally abrading or cutting the skin.
It has particular reference to the means for retaining the blade in contact with the guard and also to the construction of the guard and frame for holding the blade, and the object of my invention is to provide a more simple arrangement of the guard and frame-work which carries the razor blade than any of those constructions at present in vogue and previous to my invention in so far as I am at present aware.
The features characteristic of my invention are depicted in the drawings hereto attached which form a part of this specification and are referred to in the descriptive matter thereof relative thereto and the distinct features of novelty are more particularly pointed out in the claims.
With reference to the drawings:—
In the several figures, similar characters of reference are employed to designate like parts throughout where they occur, wherein,
The principle of the invention is involved in the action of the crimped or sinuously formed metallic guard
As will be observed more particularly with reference to
The crimped portions extending upward against the edge of the blade between the portions
The frame consisting of the guard
For compactness particularly when my improved safety razor is to be carried in the pocket, I detach the handle
It will be observed in
Having fully described my invention I claim as new and desire to secure by Letters Patent of the United States.
1. In a safety razor, a guard formed of crimped wire provided with terminal loops adapted to engage the corners of the blade at the cutting edge thereof, and the intermediate portion of the guard being bent backwardly from the edge of the blade in the manner of a loop, and a ferrule provided with a hooked extension clamped to the loop of said guard.
2. In a safety razor, a frame consisting of a split ferrule, and a wire guard secured thereto and carried thereby, said wire guard being bent intermediately in the manner of a loop and laterally therefrom along the edge of the blade in both directions from the center thereof into a series of crimps, and the terminals of said guard being bent in the manner of loops and adapted to grip the corners of the blade at its cutting edge, and a hooked extension carried by the ferrule for gripping the blade intermediately at the opposite edge, and a handle provided with a neck and shoulder for the split ferrule.
3. In a safety razor a yielding frame consisting of a crimped wire guard and a split ferrule secured thereto, said guard having an intermediate loop secured to the ferrule and a plurality of crimped portions extending in both directions along the edge of the blade and terminal loops formed at the extremities of the guard for gripping the corners of the blade at its cutting edge and a hooked extension formed upon a terminal of the ferrule for gripping the back of the blade intermediately.
4. In a safety razor a frame consisting of a ferrule, provided with a handle at one extremity, and a crimped wire guard at the opposite extremity thereof, a clip extending from the ferrule to grip the back of the razor blade, and a pair of intermediately situated crimped arms extending from the guard in opposite directions along the edge of the blade provided with terminal loops for gripping the corners of the blade at its cutting edge.
5. In a safety razor, a frame, provided with a handle connection, consisting of a blank of sheet metal bent into the form of a tube provided with a pair of securing clips and a crimped wire guard secured to said clips, and a third clip intermediately situated with respect to the former clips, adapted to engage the back of the razor blade intermediately, said wire guard being provided with a pair of crimped arms extending in opposite directions along the edge of the blade, having the crimped portions of said guard in juxtaposition to the edge of the said blade, and a pair of oppositely situated loops formed on the respective terminals of said crimped arms, adapted to engage the corners of the blades at its cutting edge.
6. In a safety razor, a frame having a split ferrule adapted to yieldingly grip the razor handle, a crimped wire frame secured to the ferrule, provided with terminal loops to engage the corners of the razor blade at its cutting edge, and an intermediate loop extending from the ferrule, said loop co-acting with the former loops to yieldingly grip the blade.
7. In a safety razor a crimped wire guard provided with terminal loops, said loops having abutments adapted to engage the corners of the blade at respectively the ends and the cutting edge thereof and the intermediate portion of said guard being bent backwardly from the edge of the blade in the manner of a loop and a ferrule provided with a pair of securing clips secured to the said loop of the said guard and a rear abutment extending from the ferrule adapted to engage the back of the blade.
8. In the herein described invention the crimped guard and ferrule carried thereby, provided with oppositely situated retaining loops formed integral with the guard and adapted to retain the blade relative to the crimps and abutments formed in the loops adapted to co-act with the blade and restrict the same against respectively transverse and lateral movement and an extension clip from the ferrule adapted to engage the rear and upper edge of the blade.
In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
Philip K. Stern.
