IMPROVEMENTS IN APPARATUS FOR CLEANSING AND POLISHING KNIVES
Year: 1865

page_text: LETTERS PATENT to George Kent, of High Holborn, in the County of
Middlesex, for the Invention of "IMPROVEMENTS IN APPARATUS FOR
CLEANSING AND POLISHING KNIVES."
Sealed the 27th June 1865, and dated the 4th January 1865.
PROVISIONAL SPECIFICATION left by the said George Kent at the
Office of the Commissioners of Patents, with his Petition, on the 4th
January 1865.
I, GEORGE KENT, of High Holborn, in the County of Middlesex, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN APPARATUS FOR
CLEANSING AND POLISHING KNIVES," to be as follows:-
This Invention has for its object improvements in apparatus for cleansing
and polishing knives. For these purposes, in order to give elastic support to
the strips of leather employed in knife cleaning and polishing machines I
employ strips of cloth of woven horsehair, or other strong hair or bristles.
These strips of woven cloth are, by preference, folded in their length, and their
edges are fixed, producing when desired, in each case a hollow tubular support
at the back of the strip or piece of leather to which it is applied. These woven
elastic supports do not project so far from the surface to which their edges and
the edges of the strips of leather are fixed as the outer edges of the strips of
leather project, hence the elastic woven supports do not act on or come in
contact with the knives. In place of or in conjunction with these woven elastic
supports, hollow tubular vulcanized india-rubber supports are employed by me.

page_text: These hollow tubular supports of india-rubber may be made into complete
tubes formed with longitudinal fins or projecting ridges to facilitate their being
fixed parallel with the edges of the strips of leather which they are to support ;
or narrow strips of sheet vulcanized india-rubber may be folded longitudinally,
the edges thereof being fixed at the backs of the strips of leather which they
are to support; or a sheet of vulcanized india-rubber may have several folds
formed in order that the strips of leather may be supported by the several
folds of the india-rubber.
In some cases steel-tempered wire is employed by me bent into vandykes,
one vandyke bend resting on other such bends; or strips of steel are used
in combination with the above or separately, with numerous cuts at the upper
edges, in order to form numerous narrow springs. These elastic supports are
applied at the backs of the strips of leather, so as not to project so far as the
strips of leather, in order that the elastic supports may not, when in use, come
against the knives which are in the machines.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Kent in the Great Seal Patent Office on the 4th
July 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
KENT, of High Holborn, in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of January, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said George Kent, Her special licence tha. I, the said George Kent, my
executors, administrators, and assigns, or such others as I, the said George
Kent, my executors, administrators, and assigns, should at any time agree.
with, and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN APPARATUS
FOR CLEANSING AND POLISHING KNIVES," upon the condition (amongst others)
that I, the said George Kent, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same to

immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said George Kent, do hereby declare
the nature of the said Invention, and in what manner the same is to bo
performed, to be particularly described and ascertained in and by the following
statement thereof, that is to say :-
This Invention has for its object improvements in apparatus for cleansing
and polishing knives. For these purposes in order to give elastic support to.
the strips of leather employed in knife-cleaning and polishing machines, I
employ strips of cloth of woven horsehair, or other strong hair or bristles.
These strips of woven cloth are, by preference, folded in their length, and
their edges are fixed, producing when desired, in each case a hollow tubular
support at the back of the strip or piece of leather to which it is applied.
These woven elastic supports do not project so far from the surface to which
their edges and the edges of the strips of leather are fixed as the outer edges
of the strips of leather project, hence the elastic woven supports do not act
or come in contact with the knives. In place of or in conjunction with
these woven elastic supports hollow tubular vulcanized india-rubber supports
are employed by me. These hollow tubular supports of india-rubber may be
made into complete tubes formed with longitudinal fins or projecting ridges
to facilitate their being fixed parallel with the edges of the strips of leather.
which they are to support, or narrow strips of sheet vulcanized india-rubber
may be folded longitudinally, the edges thereof being fixed at the backs of the
strips of leather which they are to support; or a sheet of vulcanized india-
rubber may have several folds formed in order that the strips of leather may
be supported by the several folds of the india-rubber.
In some cases steel-tempered wire is employed by me, bent into vandykes,
one vandyke bend resting on other such bends, or strips of steel are used in
combination with the above, or separately, with numerous cuts at the upper
edges in order to form numerous narrow springs. These elastic supports are
applied at the backs of the strips of leather, so as not to project so far as the
strips of leather, in order that the elastic supports may not, when in use,
come against the knives which are in the machines.
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.
DESADIDION OR OD DRIVAS

page_text: modes according to my improvements for giving clastic support to the strips of
leather a, a, a.
The part A shows the strips of leather supported by woven fabric of strong
hair or bristles, a transverse section of which is shown at Figure 2. It is
preferred that the woven cloth used should be wholly of hair or bristles; but
it may be mixed with other sufficiently elastic material; and it is preferred
that the cloth should be bent into a tubular form, as shown in Figure 2, but
this is not essential.
The part B, in Figure 1, represents the arrangement when vulcanized
india-rubber is used in a tubular form having webs or fins to fix each tube
with the strips of leather a, a, to the revolving surface, as shown at Figure 3;
or the vulcanized india-rubber strips may be folded into tubular forms, and the
two edges of each strip fixed with its strip. of leather, as shown in Figure 4,
and at C in Figure 1. Or the sheet vulcanized india-rubber may have several
folds, and each fold support a strip of leatlier, as shown in Figure 5, and at D
in Figure 1..
. When using steel wire, I do so as shown at E, Figure 1. I bend the wire
into the forms shown at Figure 6, or the bends may be less or more rounding
or more angular; by this means the neighboring bends support each other;
or in place of bent wire strips of steel may be used, formed with upright cuts,
as shewn at Figures 7, and at F in Figure 1.
I make no claim to the use of strips of leather; but I claim the means
herein described for giving elastic support to such strips of leather.
In witness whereof, I, the said George Kent, have hereunto set my hand
and seal, this Third day of July, in the year of our Lord One thousand
eight hundred and sixty-five.
