To all whom it may concern:
Be it known that we, Frederick Kampfe, Richard Kampfe, and Otto Kampfe, citizens of the United States, residing in New York, borough of Brooklyn, and State of New York, have invented certain new and useful Improvements in Razor-Blade-Stropping Devices, of which the following is a specification.
This invention relates to an improved razor-blade-stropping device by which the razor-blade can be stropped in an effective and reliable manner without injury to the strop during the stropping operation and by which the blade can be readily changed from the blade-holder without impairing the back of the holder and producing thereby edges by which the surface of the strop is scratched off or impaired; and for this purpose the invention consists of a razor-blade-stropping device comprising a blade-holder for the blade, a handle, and a disk-shaped guard device arranged between the blade-holder and handle, said blade-holder being arranged at an obtuse angle of inclination to the axis of the handle.
The invention consists, further, of a razor-blade-stropping device comprising a blade-holder, a handle for the same, said blade-holder being arranged at an obtuse angle of inclination to the handle, and a swivel connection between the blade holder and handle; and the invention consists, lastly, of a razor-blade-stropping device in which the blade-holder is provided with elongated slots and filling-pieces corresponding in shape therewith and connected by a narrow shank with the body of the blade-holder, so that the proper degree of elasticity is imparted to the jaws of the blade-holder without cutting holes in the back of the same.
In the accompanying drawings,
Similar letters of reference indicate corresponding parts.
Referring to the drawings,
The back of the blade-holder A has heretofore been provided with elongated slits, so as to impart a greater elasticity to the converging side walls of the blade-holder, and thereby facilitate the insertion of the blade into the blade-holder or its removal from the same. The slits reduce the stiffness of the sides of the blade-holder; but they are objectionable inasmuch as the edges of the holes are liable to scratch the face of the strop and to impair its smoothness. For the purpose of preventing this injury to the strop the blade-holder is punched with elongated or elliptical slits
We do not desire to claim in this application, broadly, the connection of the blade-holder with the handle under an obtuse angle of inclination to the axis of the latter, as this has been more fully shown and described in a separate application made concurrently herewith, Serial No. 106,233, filed May 7, 1902.
Having thus described our invention, we claim as new and desire to secure by Letters Patent—
1. A razor-blade-stropping device, consisting of a blade-holder, a handle connected therewith and arranged in constant relation to said blade-holder at an obtuse angle, and a guard provided on said blade-holder adjacent the handle, substantially as set forth.
2. A razor-blade-stropping device, consisting of a blade-holder, a handle connected with the same at an obtuse angle of inclination thereto, a swivel-joint between the handle and the blade-holder, and a finger-piece arranged at said swivel-joint and movable with the blade-holder, substantially as set forth.
3. A razor-blade-stropping device, consisting of a blade-holder having a socket, a handle for receiving said socket, said blade-holder being arranged at an obtuse angle of inclination to the axis of the handle, a guard-disk provided at the socket of the blade-holder, and a swivel-joint between the blade-polder socket and handle, substantially as set forth.
4. In a razor-blade-stropping device, the combination of a blade-holder provided at its back with slits forming openings, and filling-pieces in said openings connected by shanks with the back of the blade-holder, 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.
