PROVISIONAL SPECIFICATION.
Improvements in Appliances for Cleaning and Polishing Knives
and other Artioles.
I, SAMUEL RIDEAL, of Clopton Street, Hulme, Manchester, in the County of
Lancaster, Civil Engineer, do hereby declare the nature of this invention to be
as follows:-
My invention relates to cleaning and polishing the blades of knives used for
domestic purposes and has for its object to produce an appliance or appliances
extremely simple capable of cleaning and polishing knife blades or similar articles
quickly and which shall be inexpensive portable easily handled and complete in
itself and not require powder paste or other compound or adjunct to attain the
result desired.
I make my improved knife cleaners of paper felt cloth wood sheet metal woven
wire leather or other suitable material coated or mixed with size rubber gums or
other suitable matter containing an admixture of sand ground glass flint emery
metallic ore or other substances having cutting or abrading properties. Each
surface or side of the paper cloth etcetera so treated being made of a different
grade or degree of fineness to the other and also quite different in colour for ready
distinction. The above materials being made in sheets of any required dimensions
and strength are then cut into strips squares discs or other shapes and of any
convenient size and folded stitched or otherwise secured together in layers or book
form with the coarse and fine surfaces placed alternately.
In using the cleaner it is held in one hand whilst the knife blade is passed
briskly between the leaves or folds of the cleaner the necessary pressure being
given by means of the thumb and finger holding the cleaner. The coarse surfaces
being used for removing stains or rust and the finer for giving a finishing polish to
the knife blades.

Improvements in Appliances for Cleaning and Polishing Knives
and other Articles.
"
I, SAMUEL RIDEAL, Clopton Street, Hulme, Manchester, in the County of
Lancaster, Civil Engineer, 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 :-
My invention relates to cleaning and polishing the blades of knives used for
domestic purposes and bas for its object to produce an appliance or appliances
extremely simple capable of cleaning and polishing knife blades or similar articles
quickly and which shall be inexpensive portable easily handled and complete in

page_text: result desired.
que porach paste Compound or adjunct tO AUTA
It consists essentially of a portable knife cleaning appliance consisting of sheets
of thin or flexible material coated on both sides with suitable abrasive material of
different grades of fineness and then folded and secured in book form so that a
knife blade may be easily inserted between any two folds and polished by moving
it to and fro therein.
It will be fully described with reference to the accompanying drawings in which
as examples I have shown several methods of securing or connecting together the
folds of material.
Fig. 1. Side view of one form of the knife cleaner with the folds extended or
open.
Fig. 2. Front view of same.
Figs. 3 and 4. Front view and section of a modified form of securing the folds
together.
Figs. 5 and 6. Front view and section of another modification in oblong form.
Figs. 7 and 8. Front view and section of another modification.
Figs. 9 and 10. Front view and section of another modification in circular
form.
The sheets from which these knife cleaners are constructed may be of paper,
cloth, felt, leather, wood, metal, woven wire or other suitable material to both
sides of which are applied a layer or coating of emery sand, ground glass, flint,
metallic ore, or other material having cutting or abrasive properties. The material
or materials may be caused to adhere to the sheets by glue, size, rubber, gum or
other cement. One side or surface of the sheet is coated with a material of a
finer grade or degree than the other and also preferably of different colour to
render them more distinctive.
The sheets thus prepared are then folded or cut into small sheets A of any
convenient size or shape such as square, oblong, oval, circular or other convenient
shape and are folded, rivetted, stitched or otherwise secured into layers of book or
other suitable form with the coarse and fine surfaces placed alternately two fine
surfaces a being adjacent to each other and two coarse surfaces b adjacent.
I at present prefer to use calico or similar cloth coated on both sides with
emery in either of the forms illustrated the outside being protected by a sheet or
covering B of stout material such as card board or the like.
It is to be understood that other forms may be adopted and where stiff sheets
such as wood, metal or the like are employed the joints whereby they are secured
together are to be sufficiently flexible to allow the sheets to separate for the
insertion between them of the knife blades.
Referring to Figs. 1 and 2 the invention is shown in its simplest form the sheet
of material being cut into a long strip and then folded into a number of small
sheets A with concertina folds so as to bring the sides a coated with fine material
together and the sides & coated with coarse material together.
In Figs. 3 and 4 the appliance is shown comprising a number of small sheets A
laid together with the smooth surface a of oue against the smooth surface a of the
next and the coarse surface against the coarse surface b of the next. At the
outside are placed sheets or covers B of stiff strong cardboard or the like the whole
being held and secured together by two hollow metal rivets C.
In Figs. 5 and 6 the sheets of which the appliance is comprised are of double
the size and are secured by the hollow metal rivets C at the centre leaving both
ends free to be used. In addition to making the sheets with a material of finer
grade on one side than the other sheets of two different grades may be employed
and divided by a centre sheet D of cardboard or like material.
The outsides are
covered or strengthened by the sheets B of cardboard.
In Figs. 7 and 8 the appliance is comprised of two sets of sheets A of different
grades secured together in a single book by the backs or sheets B of cardboard.
One pair of rivets C securing one set of sheets A and the other pair of rivets the

page_text: other set of sheets. In this way one end may be made up of leaves coated with
fine material on both sides alike and the other end may be made up of leaves
coated with coarse material on both sides alike.
In Figs. 9 and 10 the appliance is shown in circular form with the leaves A
coated on one side with fine and on the other side with coarse material and placed
so that two fine surfaces a come together and two coarse surfaces b come together.
The outer coverings B are of stiff board and are secured in the centre by a hollow
rivet C. These may be divided into sets of coarse and fine by a central sheet of
cardboard D. The outer covering B is preferably of smaller sheets than the
abrasive sheets A to allow of the edges being flexible and spreading to permit the
knife blade to enter between them.
The outer covers are divided into one or more spaces E which are utilized for
advertising purposes by having advertisements printed thereon or printed labels
affixed thereto.
It is to be understood that the invention is not limited to the exact forms and
arrangements described as these may be varied to suit different requirements. At
the same time I wish it to be clearly understood that I do not claim per se the
use of emery covered material for polishing purposes but
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A portable appliance for cleaning or polishing knives comprising a number of
sheets or leaves of thin or flexible material having both sides coated with suitable
abrasive material secured together in book form between the folds of which a knife
blade can be inserted substantially as described.
2. A portable appliance for cleaning or polishing knives comprising a number of
sheets or leaves of thin flexible material coated on both sides with abrasive
material that on one side being finer and of different colour to that on the other,
stiff cardboard covers or backs provided with spaces for the display of advertise-
ments and secured together by hollow rivets substantially as described.
3. An appliance for cleaning or polishing knives constructed and arranged
substantially as described and shown either with reference to Figs. 1 and 2, Figs. 3
and 4, Figs. 5 and 6 Figs. 7 and 8, or Figs. 9 and 10 of the drawings.
