To all whom it may concern:
Be it known that I, Ernst Scharff, manufacturer, residing at 18 Fahrgasse, Frankfort-on-the-Main, German Empire, have invented new and useful Improvements in Safety-Razors, of which the following is a specification.
My invention relates to safety-razors, and more especially to the means whereby the razor-blade is clamped in the casing.
In the accompanying drawings,
I am aware that set-screws have been applied to one-armed levers in safety-razors and that bell-crank levers have been used before my invention, especially in connection with springs; but
What I claim as my invention, and desire to protect by Letters Patent, is the following:
1. In a safety-razor, the combination of the casing forming a support for one side of the blade, a practically-unyielding stop arranged to engage the other side of the blade, a bell-crank lever pivoted on the casing at the rear thereof and having one arm carrying said stop, and an adjusting device rigidly connecting the other arm of the bell-crank lever with the casing to move said stop toward or from the adjacent portion of the casing.
2. In a safety-razor the combination of a pressing-lever with a pivotal connection at the rear side of the casing and a pressing-screw protruding through the rear wall of the casing and having a head which bears against said wall.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
