To all whom it may concern:
Be it known that I, Otto Kampfe, a citizen of the United States of America, residing in the borough of Brooklyn, in the county of Kings, city and State of New York, have invented an Improvement in Safety-Razor Blades, of which the following is a specification.
Safety razors have heretofore and of late been provided with blades of thin flexible steel and it has been common practice to furnish a shaving outfit with a dozen or more in number of such blades which because they are comparatively inexpensive have been discarded and thrown away as soon as they lose their edge with use, instead of making any effort to re-sharpen them. In fact, these blades have not been adapted to be re-sharpened. These thin flexible normally flat steel blades have been removably placed in a suitable holder and secured for use in a transversely bent form and in a longitudinally bent form, and where bent were flexed and put under tension by the act of placing and securing the blade in the holder.
My invention relates to adapting a thin flexible steel blade for use in the holder of the well-known Star safety razor of my make; the blade at the same time being longitudinally bent, flexed and curved as shown and described in applications for Letters Patent therefor filed by me one October 2, 1906, Serial No. 337,152; one July 20, 1907, Serial No. 384,798, and one October 6, 1909, Serial No. 521,270. The guard-comb is also bent between the end holding means to the curve given to or desired of the blade and the blade is secured in a bent and flexed form to a metal frame also of like curve or arc located along one edge thereof. In this manner the blades are each given a permanent curved form to fit the holder, which except for the bend given to the guard-comb is of well-known construction. This frame is of elongated flat
In the drawing I have represented both the holder and the blade and in this drawing
Referring particularly to the holder which shows a two-part blade-carrying frame elongated and connected with the handle,
The foregoing description has reference to the well-known form of razor blade holder comprising my Star safety razor except that in the present instance the guard-comb
I claim as my invention:
1. As a new article of manufacture, a thin, flexible razor blade and a bent or curved frame secured thereto along one edge thereof.
2. As a new article of manufacture, a thin, flexible razor blade and a bent or curved frame receiving one edge of the blade and secured thereto so as to impart a permanent bent or flexed form to the blade.
3. As a new article of manufacture, a thin, flexible razor blade sharpened along one longitudinal edge, and a metal frame of flattened
