To all whom it may concern:
Be it known that I, William J. Moore, of Washington, in the District of Columbia, have invented a certain new and useful Improvement in Safety-Razors, and do hereby declare that the following is a full, clear, and exact description thereof.
The object of my invention is to provide a safety razor in which can be used a blade of thin or sheet steel, which may be secured to the handle or holder by the impingement of the end of a screw upon the inner or under side of the blade structure so as to secure the engagement or contact of the cutting edge of the blade with the surface of the guard by a rocking or lever-like action, a safety razor of this type being of very simple construction, and the blade while susceptible of all required adjustment, is firmly held. The use of sheet steel for the razor blade is desirable, because of the cheapness of the blades thus made, and it is for that reason that I have made this invention to enable blades made of sheet steel to be used in safety razors of the type I have just described.
As I prefer to construct a safety razor embodying my invention, I employ a holder that consists of a plate
The blade of my razor consists of a piece or strip
In the form of my invention illustrated in
In the form of my invention illustrated in
It may be desirable in both forms of blade illustrated to render them applicable to the holder either side up, and in this case a screw-engaging wall or rib
The back
The recess or cavity to form the rib
Having thus described my invention, what I claim is—
1. A blade for safety razors, composed of a piece or strip of sheet metal, and a back having a blade-receiving slit, said back having on one side a fulcrum-engaging surface, and on the opposite side in rear of the fulcrum-engaging surface a screw-engaging rib, a recess being formed in advance of said rib.
2. In a safety razor, the combination of a blade holder consisting of a plate forming a guard for the blade and an overhanging projection, a blade composed of a strip of sheet metal and a back overlapping opposite sides of the strip, said back having a recess or cut away portion on one side, forming a rib at the rear of the back, and on its other side a projection-engaging surface, and a screw engaging a threaded opening in said plate and having its end impinging on said rib in rear of said projection-engaged surface, said blade being shiftable in a direction crosswise of the screw.
3. In a safety razor, the combination of a blade holder consisting of a plate forming a guard for the blade and an overhanging projection, a blade composed of a strip of sheet metal and a back overlapping opposite sides of the strip, said back having a recess or cut away portion on both sides, forming on each side a rib at the rear of the back, and having on each side a projection-engaging surface, and a screw engaging a threaded opening in said plate and having its end impinging on that one of said ribs, which is contiguous to the plate, and at a point in rear of said projection-engaged surface, said blade being shiftable in a direction crosswise of the screw.
4. In a safety razor, the combination of a blade holder, a blade, stops to fix the position of the cutting edge of the blade at different positions with reference to the guard according to the degree of closeness of the shave desired the blade being shiftable forward and backward between said stops, and means to hold the blade in either of its said positions.
5. In a safety razor, the combination of a blade holder, a blade, stops to fix the position of the cutting edge of the blade at different positions with reference to the guard according to the degree of closeness of the shave desired, said stops consisting of a blade-engaging flange on the holder, and projections on the guard, the blade being shiftable between said stops so that it may be moved from engagement with one to engagement with the other, and means to hold the blade in its said two positions.
In testimony that I claim the foregoing I have hereunto set my hand.
William J. Moore.
