PROVISIONAL SPECIFICATION.
An Improved Scissor Sharpener.
I JOSEPH MILLER Senr. 27 Oswald Street Blackburn Lancashire do hereby
declare the nature of this invention to be as follows :-
According to my invention I construct a scissor sharpener of a slab or block of
unglazed porcelain, emery, or both combined, or other suitable hard material, that
will have a grinding, or abraiding effect upon steel, which slab or block is held in a
frame, in such a position, as to form an inclined plane, bevelled top and bottom, angled
to centre, at about 40 and 45 degrees so that the scissors being introduced, on
the slab or block, in centre, and worked upwards from point to heel by pressure
and backwards towards the heel of scissors will exercise a grinding effect upon both
blades, so has to effectually sharpen the same. The slab or blocks are made with
dovetailed or square edges sliding into corresponding dovetail or square shaped
frame, so has to be held by the latter, in such a manner, as to be readily
removable, when worn or damaged, for being replaced by new ones.
The frame may be fixed to a handle or a stand.

JOSEPH MILLER Senr. Draper 27 Oswald Street Blackburn, in the County of
Lancaster England 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 :-
According to my invention, I construct a scissor sharpener of a slab or block of
unglazed porcelaine or emery, or both combined, or ground asbestos, and emery
or other suitable hard material, that will have a grinding or abraiding effect
upon steel, which slab or block, is held in a frame, in such a position as to
form an inclined plane, bevilled top and bottom, angled to centre, at about
40 and 45 degrees, so that the scissors, being introduced on the slab or block
in centre, and worked upwards, from point to heel, by pressure, and backwards
towards the heel of scissors, will exercise a grinding effect upon both blades, so
has to effectually sharpen the same. The slab, or blocks, are made with dovetailed or
square edges, sliding into corresponding dovetail or square shaped frame, so has to be
held by the latter, in such a manner, as to be readily removable when worn or
damaged, for being replaced by a new one.
The frame may be fixed to a handle or stand.
Figure 1 of the accompanying drawing, shows by way of example, a perspective
view of a scissor sharpener of the above described construction, fitted with a
handle.
T

page_text: A is a slab of suitable hard grinding material, the sides of which are square. These
sides are secured in a metal frame B so that they can be slid, in, and out of the
same, the slab being so arranged, that on introducing it between, and when working
it up, from point to heel, the angle formed, will have a sharpening effect upon the
bevil of the scissors, which may still further be improved, by taking each blade of
the scissors, and working backwards and forwards, on the bevil of the hard grinding
material. The frame B is secured in a handle C. The slab A, can be withdrawn, if
it becomes defective, and replaced by a new one.
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. A scissor sharpener consisting of a slab or block of hard grinding material
bevilled top and bottom, angled to centre substantially as described.
2. A scissor sharpener, consisting of a slab of hard grinding material, removably,
fitted with square edges, into a frame, substantially as described.
3. A scissor sharpener consisting of a slab A of hard grinding material having
square sides and fitted into a square frame B substantially as described.
