To all whom it may concern:
Be it known that we, Frederick Kampfe, Richard Kampfe, and Otto Kampfe, citizens of the United States, and residents of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Machines for Stropping Razor-Blades, of which the following is a specification.
The object of our invention is to provide a new and improved machine for stropping razor-blades which is simple in construction, strong and durable, and reliable and effective in action.
In the accompanying drawings, in which like letters of reference indicate like parts in all the figures,
As shown in
The rod
The blade-holder
A friction-plate
The friction-plate
The blade
As shown in
So as to permit of detaching the blade-holder
Having described our invention, what we claim as new, and desire to secure by Letters Patent, is—
1. In a razor-blade-stropping device, the combination with a handle-frame, of a segmental rack on said frame, a rod pivoted on said frame concentric with the rack, a pinion mounted loosely on said rod and engaging the rack, a blade-holder connected with the pinion and a friction-plate pivoted to the frame concentric with the pivoted rod on that face of the handle-frame opposite the one on which the rod is mounted and mounted to swing with said rod, substantially as herein set forth.
2. In a razor-blade-stropping device, the combination with a handle-frame, of a segmental rack on said frame, a rod pivoted on said frame concentric with the rack, a pinion mounted loosely on said rod and engaging the rack, a blade-holder connected with the pinion and a friction-plate pivoted to the frame concentric with the pivoted rod, below the blade-holder and in line therewith and mounted to swing with the same, substantially as set forth.
3. In a razor-blade-stropping device, the combination with a handle-frame, of a segmental rack on said frame, a rod pivoted on said frame concentric with the rack, a pinion mounted loosely on said rod and engaging the rack, a blade-holder connected with the pinion and a friction-plate pivoted to the frame concentric with the pivoted rod and having lugs projecting upward at opposite sides of the lower end of the blade-holder, substantially as herein set forth.
4. The combination with a handle-frame, of a segmental rack on said frame, a rod pivoted on said frame, concentric with the rack, a pinion mounted loosely on said rod and engaging the rack, a blade-holder connected with said pinion, and a cross-piece on said frame extending across and over the pivoted rod, substantially as herein set forth.
5. The combination with a handle-frame, of a segmental rack on said frame, a rod pivoted detachably on said frame, concentric with the rack, a pinion mounted on said rod and engaging the rack, a blade-holder connected with the pinion and a latch for locking the rod on the frame, substantially as herein set forth.
6. The combination with a handle-frame, of a finger-rest upon each side of the same, a palm-rest button on the lower end of the frame, a segmental rack on the frame, a rod pivoted on said frame concentric with the rack, a pinion on said rod engaging the rack and a blade-holder connected with said pinion, substantially as herein set forth.
7. In a stropping device, the combination with a handle-frame, of a finger-rest on each side edge of the same, a button on the lower end, a reversible blade-holder and means for automatically reversing said holder, substantially as herein set forth.
8. A razor-blade holder
