To all whom it may concern:
Be it known that I, Leonidas H. Cress, a citizen of the United States, residing in West Newton, in the county of Middlesex and State of Massachusetts, have invented certain, new and useful Improvements in Blades for Safety-Kazors, of which the following is a specification.
The application for this patent is a division of my former application No. 572,743, filed July 19, 1910, patented July 4, 1911, No. 996,837.
My present invention relates to blades for safety razors of the kind shown in my former patent. In this class of razors the blades are commonly made thin to economize material, and to facilitate manufacture, and it is desirable that the blade should be provided with devices for positioning it in the holder and for preventing it from moving sidewise therein.
According to my invention I provide a blade made of thin steel, of proper thickness to hold an edge but not so thin as to be flexible or necessarily so as no flexible quality in the blade is required. It is formed on opposite sides near its rear edge with laterally projecting lugs which serve as handles or finger-rests when inserting the blade in the holder. These lugs are extended rearwardly, serve in positioning the blade and prevent sidewise movement thereof.
In the accompanying drawings.:—
While the blade is especially designed for use in the particular blade-holder shown it may be used in safely razors of different construction.
I claim as my invention:—
1. A safety razor blade having front and rear edges of substantially the same length and formed on its opposite side edges with laterally projecting lugs having portions extending rearwardly beyond the rear edge of the blade.
2. A safety razor blade substantially rectangular in shape provided with a cutting edge on one of the longer sides, lugs on the corners opposite the cutting edge extending laterally beyond the sides and rearwardly beyond the back of the blade.
In testimony whereof, I have hereunto subscribed my name.
Leonidas H. Cress.
