COMPLETE SPECIFICATION.
Improvements in Scissors Sharpeners.
1, REGINALD HADDAN, of the Firm of Ilerbert Laddan and Co, of
18 Buckingham Street, Strand, London, W C. Patent Agent, do hereby deolare
the nature of this invention a communication to me from abroad by John
George Hermes, of Mount Vernon, NY, United States of America, Mechanical
Engineer, and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :—
The object of this invention is to provide a flat and compact scissors sharpener
which can be readily carried on the person on elsewhere, and the invention resides
in the novel features of construction set forth in the following Specification and
claim and illustrated in the annexed drawing in which-
Figme shows an edge elevation of the sharpener.
Figure 2 shows a face elevation of Fig. 1 with shear blades sectioned along
Fig. 3.
Figure 3 18 a section along y y Fig. 2.
The flat plate o handle I bas a head 2 lying in the plane of the handle so that
the entire devico will be flat and not bulky so as to be readily carried as in the vest
pocket or in a work basket or the like. The plate is provided with the edges 3 and 4
and the head with the edges 5 and 6.
The edges and 6 are placed in alignment with one another. The edges 3 and 5
are placed out of alignment and parallel to one another. At the angles or
meeting portions of the edges 4, 5 and 3, 6 the plate and head have the recesses or
undercuts 7.
The blades 8 of a scissors or shears as known have the inner or meating sides 9
straight or plain and the outer sides 10 have the bevels 11 leading to the cutting
edges of the blades Both blades can be sharpened simultaneously by this
sharpener, since when the instrument is passed in between the opened blades and said
blades are then compressed or closed against the edges 3 and 5 and the device
moved along the blades, the bevels 11 which compress or sit firmly against the
edges 3 and are cut or pared off to make or restore the cutting edge. At the
same time the sides 9 rest or are guided so lightly against edges 4 and 6 that
the straightness or alignment of said sides 9 will not be disturbed or cut off The
recesses or undercuts 7 prevent the cutting edges of the blades coming into any
contact by which such edges would be dulled, nicked or injured during the
sharpening operation by the instrument.
The plate or handle 1 and head 2 being formed or cast in one piece will form a
cheap and practically indestructible niticle
The edges 3 and 5 as seen in Fig. 3 are tapered or convergent in transveise
section so that their contracted or convergent portions lie toward the joint or angle
formed by the open shear blades.
The device being made of tool steel hardened will possess the requisite cutting
or paring capacity.
Having now particularly described and ascertamed the nature of this inven
tion and in what manner the same is to be performed declare that what I
claim 18:
1. As a new article of manufacture a scissors sharpener comprising a flat plate
or handle provided with a flat bead lying in the plane of the handle, said plate and
head being provided with the edges 4 and 6 placed in aligument with one another

page_text: and with the edges 3 and 5 placed out of alignment and parallel with one another,
said plate and head having recesses or undercuts at the meeting portions of the
edges 4, 5 and 3, 6 substantially as described.
2 As a new article of manufacture a scissors sharpener comprising a flat plate or
handle provided with a flat head lying in the plane of the handle, said plate and
hend being provided with the edges 4 and 6 placed in alignment with one another,
and with the edges 3 and 5 placed out of alignment and parallel with one another,
said plate and head having recesses or undercuts at the meeting portions of the
edges and said plate and head being formed integral with one another substantially
as described.
3. As a new article of manufacture a scissors sharpener comprising a flat plate or
handle provided with a flat head lying in the plane of the bandle, said plate and
head being provided with the edges 4 and 6 placed in alignment with one another,
and with the edges 3 and 5 placed out of alignment and parallel with one another,
said plate and head having recesses or undercuts at the meeting portions of the
edges 4, 5 and 3, 6 and the edges 3 and 5 being made convergent or non-parallel in
transveise section substantially as described.
