COMPLETE SPECIFICATION.
Combined Knife Sharpener and Holder for a Hone-stone or an
Emery or other Plate having a Suitable Sharpening Surface.
I, CHARLES ARTHUR ALLISON, of 52 Chancery Lane, Londor, in the County
of Middlesex, Patent Agent, do hereby declare the nature of this invention (which
has been communicated to me from abroad by John F. Yoho, Post Office box 1274,
Denver, Arapahoe County, State of Colorado, United States of America
Gentleman), and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention relates to improvements in knife sharpeners, and consists of the
features hereinafter described and claimed, all of which will be fully understood by
reference to the accompanying drawing in which is illustrated an embodiment
thereof. In this drawing,
Fig. 1 is an elevation of the device.
Fig. 2 is a longitudinal section taken through the hone-stone, one of the head
plates holding the sharpening device being removed.
Fig. 3 is an edge view of the device.
Figs. 4 and 5 are sections taken on the lines p-p and r-r, respectively, Fig. 2.
Similar reference characters indicating corresponding parts or elements in these
views, let the numeral 5 designate the two head plates recessed to receive the
elliptical plates 6 which constitute the sharpeners.
The parts 6 are preferably so located that their greatest diameters are
approximately parallel. Their edges are bevelled and touch each other at a point
midway between their extremities. The head plates are slotted to expose the
adjacent edges of the sharpening plates, and to permit the introduction of the
instrument to be sharpened, as far as the meeting edges of the plates 6.
The plates 5 are further recessed to receive the extremities 7 of a handle 7
composed of some suitable wire whose extremities are bent outward so that when
the head plates are fastened together, these extremities cannot be withdrawn or
detached.
From the extremities 7, the handle is shaped suitably to embrace a hone-stone 8
whose parallel sides are grooved to receive the same. One extremity of the hone-
stone engages the head plates, while at the opposite extremity, the wire 7 is bent
inward, whereby the stone is locked in place."
From the part 7, the wire is fashioned into a suitable hand piece 74. The head
plates 5 are secured together by small screws, or in any other suitable manner.
Instead of the hone-stone, an emery or other plate having a suitable sharpening
surface may be employed for the purpose stated.
In using my improved instrument, the knife to be sharpened is inserted between
the adjacent edges of the sharpening plates 6 and drawn back and forth a few
times, or until the desired result is attained, after which, the edge of the knife may
be smoothed or further sharpened as aforesaid, upon the bone-stone or emery plate,
to any desired extent.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what
I claim is :-
As an improved article of manufacture, the herein described knife sharpener
consisting of the head plates, sharpener plates held between the recessed head
plates, the latter being slotted to expose the adjacent edges of the sharpener plates,
a wire handle connected to the head plates, and a hone-stone or emery or other

page_text: plate having a suitable sharpening surface seated between and retained by the
sides of the wire handle, substantially as described.
