EPHRAIM HAMBUJER, OF DETROIT, MICHIGAN, ASSIGNOR TO IRA A. METOALF, or SAME PLACE.
PENClL-SHARPEN ER.
SPECIFICATION forming part of Letters Patent No. 429,130, dated June 3, 1890.
Application filed October 12, 1889. Serial No. 326,771- (No model.)
To all whom it may concern.-
Be it known that I, EPHRAIM HAMBUJER, a citizen of the United States, residing at Detroit, county of \Vayne, State of Michigan, have invented a certain new and useful Improvement in Slate-Pencil Sharpeners; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.
My invention is designed to produce a slatepencil sharpener which can be cheaply manufactured and which will be effective in operation.
In the drawings, Figure 1 is a perspective View of my sharpener. Fig. 2 is a plan View of the under side of the same.
In the manufacture of my sharpener I prefer to construct it of cast-iron and afterward nickel-plate it; but I would be understood as including by my invention any manner of constructing it and any suitable metal to be used in the construction.
In carrying out my invention,A represents the serrated portion on which the pencil is sharpened, and B the portion forming the handle. The serrated portion is made a trough shape, as shown at a, and in this serrated portion the pencil is laid to be sharpened. The
end of the trough is preferably provided with the slot 0, into which the point of the pencil may enter when being sharpened.
C is a tapering orifice with which the sharpener may or may not be provided. This orifice is provided with the serrations or edges 0.
To sharpen the pencil, the end may be inserted in the orifice and the blunt end tapered. The tapered end may then be placed in the serrated trough and moved back and forth until the point is formed. If a long taper is desired, the pencil may be moved back and forth with the point in the slot.
What I claim is- 1. The herein-described slate-pencil sharpener, comprising the serrated and slot-ted trough-shaped portion A, having the handle B at one end, substantially as shown and tie scribed.
2. The herein-described slate-pencil sharpener, consisting of the serrated trough-shaped portion A, having the handle 13 at one end, and provided at the base of said handle with the tapering orifice 0, having serrated edges, substantially as shown and described.
In testimony whereof I sign this specifica tion in the presence of two witnesses.
. EPHRAIM HAMBUJER. I
