SPECIFICATION forming part of Letters Patent No. 506,693, dated October 17, 1893.
Application filed February 3, 1893. Serial No. 460,917. (No model.)
To all whom it may concern.-
Be it known that we, CHARLES AKERMAN JACKSON and FRANK IRVING HAMMOND, citizens of the United States, residing in the city of Pr0vidence,-county of Providence, and the State of RhodeIsland, haveinvented anew and useful Improvementin the Acme Ink-Eraser, of which the following is a specification.
Our invention relates to that class of cuttersor scrapers which may be used for ink erasing.
The object of our invention is to obtain an efficient, durable, and inexpensive eraser. We attain this object by cutting sheet steel of the required thickness into the form of a disk, grinding or turning the periphery on a bevel to a knife edge, incasing the same in a leather, or other suitable material, answering the purpose of a holder, as is illustrated in the accompanying drawings, in which-- Flgure l is a side view of the eraser. Fig. 2, IS an edge view of the eraser. Fig. 3 is a perspective view of the casing or holder. Fig. 4 is the beveled edge disk.
The eraser is round, as shown in Fig. 4, and presents a small cutting surface at a time, so that the ink may be removed without inj uring the material. It is durable because the cutting edge is all around the periphery, and can be turned so that every point may be used before the eraser will need sharpening, which can be done very easily by grinding, or in many other ways well known to the trade.
What we claim as our invention, and desire to secure by Letters Patent, is p The combination in an ink eraser of a steel disk having a cutting or scraping edge, beveled on one side of the disk, and a case of leather or other material, substantially as herein described.
In testimony whereof we have signed our names in the presence of two subscribing witnesses.
