To all whom it may concern:
Be it known that we, Ernst Scharff and Gottfried Alexander Scharff, both subjects of the Emperor of Germany, and 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, mainly, to safety-razors in which the blade is held removably in a frame carrying a toothed guard by the blade.
The main objects of our invention are to facilitate the adjustment of the razor for use and increase the security of the blade when so adjusted, to provide for safely, quickly, and compactly folding the razor when not required for use, and to simplify and generally improve the construction.
The invention comprises various novel features, which will hereinafter be described in detail, and then pointed out in the claims.
Reference is to be had to the accompanying drawings, forming part of this specification, in which—
Like letters of reference designate corresponding parts in the various figures.
We make the frame
On opposite ends of the front portion of the toothed guard
The razor is easily closed up by simply drawing the hook-catches
We claim as our invention—
1. In a safety-razor, the combination, substantially as hereinbefore set forth, of a bifurcated resilient frame, the branches of which open or spring together, with a blade-holder and connections on one branch of the said frame to engage the front of the blade-holder at opposite ends thereof, and connections on the other branch to engage the back of the blade-holder.
2. The bifurcated self-folding frame for a safety-razor, formed of resilient wire, bent, as described, to form the two branches, rigidly connected at their lower ends, the wire forming each branch being formed at its lower part into a long loop, which said loops form the handle, and at its upper part into spread limbs, which are adapted to engage the blade-holder at opposite ends, as set forth.
3. The combination, substantially as hereinbefore set forth, with the blade-holder and the blade, of a bifurcated frame, to one branch of which the back of the blade-holder is pivoted to fold thereupon, which said branch is formed with a resilient arm to press upon the back of the blade when opened, and devices on the other branch to engage the front of the blade-holder.
4. In a safety-razor, the combination, substantially as hereinbefore set forth, with a bifurcated folding frame, of a blade-holder pivoted at its back to one branch, so that it will fold between the branches with the edge of the inserted blade directed inward, and devices on the other branch to engage the front of the blade-holder.
5. In a safety-razor, the combination, substantially as hereinbefore set forth, with a bifurcated folding frame formed of wire, each branch having two limbs, and a blade-holder pivoted to fold between the branches, of a blade-shield spanning the limbs of one branch to cover the unprotected edge of the blade when folded.
6. In a safety-razor, the combination, substantially as hereinbefore set forth, of a bifurcated frame provided with a handle, the rear limbs of the frame having bearings and the front limbs having catches, of a transverse blade-holder pivoted to said rear bearings and having studs or means to engage said catches.
In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
