PATENT OFFICE.
MosESw. DILLINGHAM, OE AMSTERDAM, NEW YORK.
IMPROVEMENT IN PENCIL-SHARPENERS.
Specification forming part of Letters Patent No.105.440, dated July 19, 1870.
To @ZZ whom it may concern/.1
Be it known that I, MosEs W. DrLLiNcHAM,
" of Amsterdam, in the county of Montgomery "and State of New York, have invented a new and useful Improvement in Pencil-Sharpeners; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification. 1
This invention relates to a new and useful improvement in an instrument for sharpening lead-pencils, whereby they are made more useful than they have hitherto been; and it consists in combining with a pencil-Sharpener an eraser for lead-marks, and also a spring for holdingthe Sharpener on a pencil, as will be hereinafter more fully described. A
In the annexed drawings, Figure 1 is a view of the pencil-Sharpener attached to a pencil, showing the lead-eraser combined therewith. Fig. 2 is a cross-Section of Fig.' 1 on the line w x, showing the spring.
Similar letters of reference indicate corresponding parts. l
l lA is the pencil-Sharpener, formed of two principal parts, A and B, jointed together, so
:as to form either a cone or a tube, and shown as the latter in the drawings, for the purpose of forming a cap to a pencil, or for keeping the Sharpener where it will be always ready for use.
C represents the lead-mark eraser-a piece of rubber-which, as seen in Fig. 2, passes through one part, A, of the Sharpener. The inner portion or button part, d, forms a spring, which bears against the pencil and serves to hold the Sharpener on the pencil in any desired position. p
I am aware. that Sharpeners made to form caps cannot be claimed,l broadly, as new, and also that rubbers attached to a pencil-sharpener for the purpose of erasing lead-marks are not new; but
What I esteem to be of my invention, and desire to protect by Letters Patent, is-
The improved pencil-Sharpener and leaderaser, consisting of the parts A B, jointed together, as described, and the rubber eraser C, having the elastic button d, all constructedand relatively arranged as and for the purpose specified.
The above specification of my invention signed by me this 4th day of April, 1870.
MOSES W. DILLINGHAM.
