To all whom it may concern:
Be it known that I, Isaac N. Brigham, a citizen of Canada, residing at Melrose Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Safety-Razors; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, making a part of this specification, and to the numerals and figures of reference marked thereon, in which—
The present invention has relation to safety razors, and it consists in the novel arrangement hereinafter described and particularly pointed out in the claims.
Similar numerals of reference indicate corresponding parts in all the figures of the drawing.
In the accompanying drawing,
For the purpose of providing means for carrying the blade and clamping the blade the clamping plates
The shank
For the purpose of providing guide ways for the clamping plates
In use I prefer to form the housing
The clamping bolts are provided with the enlarged portions
It will be understood that there can be no relative movement as between the clamping plates
It will be understood that by this peculiar arrangement the razor blade will reciprocate in true parallelism with the guard fingers or in other words the razor blade will be held in true and exact alinement at all times and under all circumstances with the guard fingers. For the purpose of providing a means for easily detaching the blade from the clamping plates
Having fully described my invention what I claim as new and desire to secure by Letters Patent, is—
1. In a power driven safety razor, a housing provided with guide ways, a razor blade, clamping plates located upon opposite sides of the razor blade, one of said clamping plates provided with a longitudinal slot, a power shaft provided with a detachable driving head, said driving head provided with a pintle adapted for engagement with the elongated slot, means for clamping the razor blade and plates together and the housings provided with guard fingers, substantially as and for the purpose specified.
2. In a power driven safety razor, the combination of a driving shaft, a casing provided with guide ways and curved guard fingers, a razor blade and clamping plates, said razor blade located intermediate the clamping plates, and means for imparting reciprocating movement to the razor blade and clamping plates, substantially as and for the purpose specified.
3. In a power driven safety razor, the combination of a casing provided with guide ways and guard fingers, a razor blade, clamping plates, said razor blade located between said clamping plates, said razor blade provided with apertures, clamping bolts provided with portions adapted to fit the apertures in the razor blade and means for imparting a reciprocating movement to the razor blade, substantially as and for the purpose specified.
4. In a power driven safety razor, a motor, a casing connected to said motor and provided with guard fingers, said casing provided with guide ways, a razor blade, clamping plates located upon opposite sides of the razor blade and guided by the guide ways of the casing, and means for imparting a reciprocating movement to the razor blade and clamping plates, substantially as and for the purpose specified.
5. In a safety razor, the combination of a casing provided with guard fingers and guide ways, a razor blade, clamping plates, means for clamping the razor blade and clamping plates together, said clamping plates provided with recesses at their ends, substantially as and for the purpose specified.
In testimony that I claim the above, I have hereunto subscribed my name in the presence of two witnesses.
Isaac N. Brigham.
