A J HOOD PENCIL SHARPENER.
Wituemax:
UNITED STATES PATENT OFFICE.
ALEXANDER J. HOOD, OF MUSOODA, ISOONSIN.
PENCIL-SHARPEN ER.
SPECIFICATION forming part of LettersPatent No. 452,270, dated May 12, 1891.
Application filed November 15, 1890. Serial No. 371,531. (No model.)
To a. whom it may concern:
Be it known that I, ALEXANDER J. HOOD, of Muscoda, in the county of Grant and State of Wisconsin, have invented certain new and useful Improvements in Pencil-Sharpeners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.
My invention relates to an improvement in pencil-Sharpeners of the construction hereinafter shown and described.
The object of my invention is to provide a cheap and simple peneilsharpener which is composed of a number of blades which are adapted to be sharpened whenever they become dulled.
Figure 1 is a side elevation of a pencilsharpener which embodies my invention. Fig. 2 is an end view of the same.
A represents a ring of any desired thickness, and from one edge of which extends a numberof blades B,which are inclined inward toward each other at their outer ends, so as to cut away the end of the pencil in the usual manner. These blades are sharpened upon their inner edges, so as to cut their full length, and have sufficient space between their edges to allow asharpening device to be applied to both sides of the edge of each blade, and thus adapt the blades to be sharpened from time to time and keep them in a perfect cutting condition. The blades and the rings will be preferably cast in a single piece; but, should it be so desired, the ring may be formed of one kind of metal and the blades formed of steel and then have their inner ends inserted in suitable sockets prepared to receive them in the ring.
Formed upon one side of the ring is a perforated flange O, by means of which the sharpen'er may be attached to the watch-chain and thus always be in position ready for use.
Having thus described my invention, I claim A pencil-sharpener consisting of a ring and a series of blades which extend substantially radially therefrom and downward, wherebya sharpening-tool can be applied to their inner edges, the said blades having their inner edges inclined toward each other from the upper to their lower edges, substantially as shown and described.
In testimony whereof I affix my signature in presence of two witnesses.
, ALEXANDER J. IIOOD.
