To all whom it may concern:
Be it known that we, Frederick Kampfe, Richard Kampfe, and Otto Kampfe, of Brooklyn, Kings county, State of New York, have invented certain new and useful Improvements in Safety-Razors, of which the following is a specification.
This invention relates to that class of razors known as “safety-razors,” in which a small blade is held in a suitable frame and provided with a guard to prevent the edge of the razor from cutting into the skin.
The invention consists in the combination, with a suitable frame, of an eccentric for holding the blade in the same, and a spirally-grooved roller or worm mounted below the cutting-edge of the blade in a swinging frame provided with suitable means for adjusting it, all as will be described hereinafter, and pointed out in the claims.
In the accompanying drawings,

The blade cannot cut into the skin, as the worm acts as a guard and runs over the skin directly in front of the blade. The special advantage of the worm or spirally-grooved roller is that all parts of the cutting-edge can act. The spiral rib or ridge forming the worm continually moves and does not remain fixed in front of any part of the edge, whereas in the razors heretofore provided with annular ribs or fixed guards only those parts of the blades cut that are between the ribs or guards, and it is this we desire to obviate.
The handle is provided at one end with a screw,
The blade is magnetized, as we find the cutting-edge is preserved on a magnetized better than on a non-magnetized blade. The roller
Having thus described our invention, we claim as new and desire to secure by Letters Patent—
1. In a razor, the combination, with the frame or casing on which the blade can be held, of a swinging frame pivoted in the frame on which the blade is held, a spirally-grooved roller or worm mounted to turn in the swinging frame, and a screw connected with the swinging frame for the purpose of adjusting it, substantially as shown and described.
2. In a razor, the combination of the frame
3. The combination, with the frame
4. In a razor, the combination, with a frame having hooks, of an eccentrically-mounted clamping-roller below the casing for the purpose of pressing the blade against said hooks and thus holding it in place, substantially as shown and described.
5. In a razor, the combination, with a frame having lugs
In testimony that we claim the foregoing as our invention we have signed our names in presence of two subscribing witnesses.
