A New and Improved Scissor Sharpener.
I, GEORGE RUFFUS FORD, of Grand Rapids, in the State of Michigan, United
States of America, Machinist do hereby declare the nature of this invention, and
in what manner the same is to be performed; to be particularly described, and
ascertained, in and by the following statement :-
This invention relates to a new and improved scissor sharpener, and 'the invention
consists in a plate and swaging bolt or rod attached thereto, inclined jaws in combi-
nation with projections, one at either side projecting at an angle less than a right
angle towards the swaging rod, and an elastic support, one ou either.side of the
swaging rod and adapted to press and retain the blades of the scissors or. shears in
contact with the inclined projections and to guide the scissors to the proper position
to be sharpened; and the object of the invention is to furnish a cheap and con-
venient device for sharpening scissors, in which the scissors' are held in proper
position to be sharpened by means of elastic guides. This object I accomplish by
means of the mechanism illustrated in the accompanying drawing, in which:-
Fig. 1.shows a perspective view of my improved, scissor, sharpener, showing the
sides of the device opposite the one to which is attached the swaging rod.
Fig. 2 shows-a plan view of my-invention showing the same side as shown in
Fig. 1.
Fig. 3 is a plan view of the reverse side showing the position of the swaging rod
or bolt upon the metallic plate.
Fig. 4 is a sectional view on line 4-4 of Fig. 2 looking in the direction shown
by the arrows.
Fig. 5 is a sectional view on line 5-5 of Fig. 3, looking in the direction shown
by the arrows in said Fig. 3.
Similar letters refer to similar parts throughout the several views.
A represents a metallic plate, of any suitable form, provided with projections,
one on either side, shown by B-B; the faces of the projections B-B being in
the same plane, and being set at an angle to a line drawn longitudinally through the
plate A.
F represents a rod of hardened steel attached to one face of the plate A, as
shown.
C. represents the elastic guides secured to the plate A, and supported preferably
by means of a wire shown by E. Instead of a wire, the support E may be made
of any suitable material to retain the elastic guide in position; the same may be
composed of a portion of the plate, or piece extending from the plate A, or in any
suitable manner for retaining the elastic guides C-C in place. These supports E
are shown by dotted lines in Figs. 2 and 3, and a section is shown in Fig. 4.
In using my invention the scissors are placed in the openings between the
projections B-B and the guides C-C, as shown in Fig. 1, and are then shut
down so as to crowd down closely against the swaging bolt F, and to be pressed
closely against the swaging projectious B-B, and they are then drawn back; the
edges of the scissors being swaged by means of the bolt, and trimmed or smoothed
in the back action of the scissors by means of the projections B-B, so that a pair
of scissors may be sharpened by a single operation providing they be pressed
sufficiently upon the blade to swage the edge as the scissors are drawn backwards
the edge being swaged by means of the round bolt, and the edges trimmed by means
of the projections B-B as above described.

page_text: If however the scissors are not sufficiently sharpened by one operation, the sanie
may be repeated. The elastic guides C-C may be made of rubber or any suitable
material. They should be placed a sufficient distance from the projections B-B to
allow for the insertion of the scissors, but near enough to crowd the scissors in
close contact with the projections B-B. The bolt F may be round or in any other
suitable form. The plate A is preferably made of steel.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed I declare that what I
claim is
1. In a device for sharpening scissors or shears, the combination of a plate
having inclined projections, a swaging rod of steel, or other suitable material,
elastic guides, one on either side of the swaging steel, adapted to press the blades
of the scissors in contact with the projections from the plate, substantially as and
for the purpose described.
2. In a scissor sharpener, the combination of a metallic plate having projections
adapted to trim or swage the sides of the scissor blades, a hardened swaging rod
or bolt, elastic guides, one on either side, for the purpose of pressing the scissor
blades in contact with the swaging projection, and metallic supports within the
elastic guides in order to give stability to such guides, substantially as and for the
purpose described.
