To all whom it may concern:
Be it known that I, Ernst Scharff, a subject of the Emperor of Germany, resident at Frankfort-on-the-Main, Germany, have invented new and useful Improvements in Safety-Razors, of which the following is a specification.
This invention relates to the mode of removably holding and adjusting the blade, and adapting the holder to suit blades of different thicknesses. The razor blade is held in a frame comprising end clips, against which it is pressed by the thrust of a screw formed on the handle and working through a screw-socket formed in the boss of the frame, the screw pressing against the under side of the blade through a curved metal tongue forming a guide to prevent injury to the edge of the razor when inserting it. By means of this screw and a jam nut thereon, the cutting edge of the blade may be accurately adjusted with regard to the upper ends of the row of curved
Reference is to be had to the accompanying drawings, forming part of this specification, wherein—
The razor blade
Having now particularly described and ascertained the nature of the said invention and in what manner the same is to be performed, I declare that what I claim is—
1. In a safety razor, a basket or frame, having guard teeth and a socket or boss provided with an external screw-thread, in combination with a curved spring
2. In a safety razor, a basket or frame having guard teeth adapted to hold the blade, and also having an internally and externally screw-threaded socket, in combination with a handle having a screw-threaded extension passing through said socket to bear upon the blade, a spring pivotally connected to the socket and bearing against the back of the blade, and a regulating nut bearing upon said spring, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
