To all whom it may concern:
Be it known that I, William C. Heimerdinger, a resident of Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Safety-Razors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to improvements in safety-razors, the object of the invention being to provide a safety-razor with two separate and independent blades located at opposite sides and held by an elastic backing in operative position and provide improved mechanism whereby said elastic backing can be adjusted to hold the blades at different angles, according to the closeness of shave desired by the user.
A further object is to provide improved means for holding the blades which permit them to be easily inserted or removed, precludes possibility of incorrectly placing them, and provides positive step-by-step adjustment to clamp the blades and adjust the angle at which they are held.
A further object is to provide the guard with grooves or ducts which permits water, lather, and hair to pass over the blades into a chamber or compartment on the holder and not collect between the blade and guard and interfere with the perfect operation of the razor.
With these and other objects in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.
In the accompanying drawings,

In operation when the step of the adjusting-sleeve
The blades may be sharpened on both edges and be reversed when dull or may be sharpened on one edge only, if desired. They can be made and sold at a very small cost, so small, in fact, as to permit the user to throw them away when dull and insert new ones.
The adjustment is perfect, requiring no exercise of judgment on the part of the user to secure the proper angle of the blade, because each movement of the adjusting-sleeve a distance of one step determines the position of the blades.
The device can be easily and quickly taken apart by removing the thumb-nut
A great many slight changes might be made in the general form and arrangement of the parts described without departing from my invention, and hence I would have it understood that I do not restrict myself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is—
1. A safety-razor comprising a holder, guards projecting laterally in opposite directions from one end of said holder, a separate blade disposed on each guard fulcrums on the guards for said blades, a single plate bearing on both of said blades, and means for adjusting said-plate relatively to the guards, to change the angle of the blades relatively to the guards.
2. A safety-razor comprising a holder, rigid guards projecting laterally in opposite directions from one end of said holder and a spring-plate having portions projecting over the respective guards for clamping a separate blade on each guard, two blades fulcrumed under said spring-plate on the rigid guards.
3. A safety-razor comprising a holder, rigid guards projecting in opposite directions from one end of said holder, a spring-plate having portions projecting over said guards for clamping a separate blade on each guard, two blades fulcrumed on said guards, under the spring-plate and means carried by the holder and connected with the center of said spring-plate for adjusting the latter.
4. In a safety-razor, the combination of a guard having a flat face and a fulcrum, a rigid blade thereagainst, and means for holding the blade against the flat face or tilted on said fulcrum away from the same.
5. In a safety-razor, the combination of a rigid guard having two members projecting in opposite directions, two independent blades to bear against the respective members of said rigid guard, said members of the rigid guard having fulcrums for the blades and_a spring backing-plate clamping the blades against the respective members of the guard and the fulcrums thereon.
6. In a safety-razor, the combination of a rigid guard having flat faces adjacent to its fingers and walls or shoulders at the inner ends of said flat faces, blades on said flat faces projecting over .the walls or shoulders, and means for tilting said blades on the walls or shoulders.
7. In a safety-razor, the combination with a guard and blades fulcrumed on said guard, of a spring backing-plate constructed to clamp the blades against the guard, a rod secured to the backing-plate and projecting through the guard, and means for moving the backing-plate and guard toward or away from each other, to cause the blades to turn on their fulcrums.
8. In a safety-razor, the combination with a sleeve having an angular bore, and a guard thereon, of a backing-plate, an angular rod secured to the backing-plate and projecting through the annular bore of the sleeve, a holding-sleeve having angular openings to receive the rod, a nut screwed onto the end of the rod, cylindrical shanks on the above-mentioned sleeves, and an adjusting-sleeve mounted to turn on said shanks and having stepped cam engagement with one of them.
9. In a safety-razor, the combination with a spring-clamp for the razor-blade, a handle connected with the clamp, and means for adjusting the spring-clamp and a step-by-step adjusting mechanism for said means.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
William C. Heimerdinger.
