To all whom it may concern:
Be it known that I, Ferdinand Erdmanski, of Hiawatha, in the county of Brown and State of Kansas, have invented a new and Improved Razor, of which the following is a specification:
In the accompanying drawing,
Similar letters of reference indicate corresponding parts.
The object of my invention is to produce an improved razor with interchangeable blades, by which not only time in honing is saved, but also a considerable economy in the use of razors produced.
My invention consists of a detachable blade, which is inserted into the supporting back part or frame of the razor, being fastened therein by its hinged top half, which is secured by a suitable slide-piece or other locking device on the lower or main part. The steady position of the razor-blade is secured by means of pins of the main part of the supporting-frame, passing through symmetrically-arranged holes of the blade into recesses of the hinged part.
In the drawing,
Any other screw or equivalent fastening device may be used, as I do not confine myself to the use of the slide-piece. One handle part and supporting-frame may thus serve for any number of razor-blades which are readily and conveniently inserted, so as to form a cheaper and more economical razor for general use.
Having thus described my invention, I claim as new and desire to secure by Letters Patent—
1. As an improvement in razors, the combination of supporting back or frame
2. The razor-blade
