To all whom it may concern:
Be it known that we, Frederick Kampfe, Richard Kampfe, and Otto Kampfe, of the city of Brooklyn county of Kings, and State of New York, citizens of the United States, have invented certain new and useful Improvements in Razor-Stropping Devices, of which the following is a specification.
Persons that are not skilled in stropping razors usually make the great mistake of turning the razor-blade over the edge while stropping, instead of over the back, thereby ruining the cutting-edge of the razor and rendering the same absolutely worthless.
The object of our invention is to provide a new and improved device for holding razor-blades and automatically reversing the same over the back of the blade at the end of the stroke, thereby rendering turning on the edge impossible.
The invention consists in a razor-stropping device provided with a friction-roller for automatically reversing or turning the blade over its back at the end of each stroke.
The invention also consists in the construction and combination of parts and details, as will be fully described hereinafter, and finally be pointed out in the claims.
In the accompanying drawings,

On a block
In case an ordinary razor is to be stropped the handle
If desired, the friction-roller may be made smaller and grooved, as shown at
If desired, a grooved friction-roller
Having thus described our invention, we claim as new and desire to secure by Letters Patent—
1. In a razor-stropping device, the combination, with the blade-holder, of a spindle adjacent to the blade-holder and carrying a friction-roller, and gearing for transmitting motion from the spindle carrying the friction-roller to the blade-holder, substantially as set forth.
2. In a razor-stropping device, the combination, with a block, of two parallel spindles, one carrying a blade-holder and the other a friction-roller, gearing for transmitting motion from the spindle carrying the friction-roller to the spindle carrying the blade-holder, and check-pins on the gear-wheel on the roller-spindle, substantially as set forth.
3. In a razor-stropping device, the combination, with the block, of two parallel spindles on the same, a friction-roller on one spindle, a blade-holder on the other spindle, cog-wheels on said spindle, check-pins on the cog-wheel of the roller-spindle, pins on the cog-wheel of the blade-holder spindle, and a spring against which the pins on the cog-wheel of the blade-holder spindle can press, substantially as set forth.
In testimony that we claim the foregoing as our invention we have signed our names in presence of two subscribing witnesses.
