To all whom it may concern:
Be it known that I, Frederick Kampfe, a citizen of the United States, residing in the borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Razors, of which the following is a specification.
My invention relates to razors, and especially to that class where the blade is detachable from the handle and shank.
In the accompanying drawings,
Similar reference-letters designate corresponding parts.
Referring now to the drawings which illustrate the preferred form of my invention,
In the back or heel of the blade
Preferably, too, the blade will be magnetized, in which event this groove increases the efficiency of the blade as a magnet, makes it easier to magnetize the blade, and conserves the magnetism to a greater extent.
When the blade is made detachable from the blade-holder, as shown in the accompanying drawings, this longitudinal groove has another function—namely, that of coacting with suitable projections arranged on the inside of the blade-holder to hold the blade firmly in position therein. For example, in the construction illustrated in the accompanying drawings the metal forming the back or heel
Additional lugs or retaining devices may be provided for the inner end of the blade by forming projections
The blade instead of having a rounded back or heel will preferably be cut square, so that the blade will stand on its back, which is a great convenience, especially in the process of washing and wiping, as it does away with the possibility of the blade adhering to the surface upon which it is rested and makes is much easier to handle the same.
What I claim as new is—
1. A razor-blade provided with a continuous longitudinal groove arranged in the back thereof, a blade-holder, and one or more projections arranged within said blade-holder and adapted to coact with the longitudinal groove in said blade.
2. A razor-blade provided with a continuous longitudinal groove arranged in the back thereof, a blade-holder having the metal of its back portion indented to form a projection adapted to coact with the continuous groove in the blade.
3. A razor-blade provided with a continuous longitudinal groove arranged in the back thereof, a blade-holder having the metal of its back portion indented to form a projection adapted to coact with the continuous groove in the blade, said projection being provided with one or more slits.
4. A razor-blade and blade-holder having an indented groove in its back, the bottom wall of the groove having portions removed therefrom to form slits.
In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
