PROVISIONAL SPECIFICATION left by the said Arthur Kinder and John
Inglis at the Office of the Commissioners of Patents, with their Petition,
on the 22nd October 1863.
We, ARTHUR KINDER, of 20, Cannon Street, in the City of London,
Engineer, and JOHN INGLIS, of Ellesmere Road, Old Ford, in the County of
Middlesex, Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE MANUFACTURE OF METALLIC FOILS AND IN THE APPARATUS
TO BE EMPLOYED THEREIN," to be as follows:-
This Invention relates to a mode of treating foils, particularly for lead and
tin, and alloys of lead and tin, during the operation of rolling, and consists in
coating or covering the surfaces of the sheets or bands when being piled into:
the pack for rolling with oily, fatty, or saponaceous matter in substitution for

page_text: the French chalk, or substances hitherto employed in the process of rolling
the packs, it having been found that the use of fatty or saponaceous matter
will enable the pack to be drawn to a considerably greater extent without
requiring the pack to be opened, thus effecting a considerable economy of time
and labour. In applying the oily, fatty, or saponaceous matter to the surface
of each sheet or band by hand, I propose to employ a pad or rubber, somewhat
similar to the pads or rubbers employed for French polishing, whereby a very
thin coating can be readily applied to the entire surface of the sheet. If
preferred the coating may be applied in the breaking down rolling mill by
causing the band or sheet as it leaves the breaking down rolls to pass between
a pair of felt rolls, one of which may be made to rotate a little faster than the
other, so as to sleek or rub the surface of the sheet or band. This roller
is supplied with oily, fatty, or saponaceous matter by means of a small perforated
roller rotating in contact with the sleeking roller, such small roller containing
a sponge or other absorbent material filled with the substance to be used in
the interior thereof, which may be readily compressed so as to cause the
matter to exude through the small roller and be applied to the surface of
the sleeking roller which lays it evenly over the surface of the sheet or
band.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Arthur Kinder and John Inglis in the Great Seal Patent
Office on the 22nd April 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ARTHUR
KINDER, of 20, Cannon Street, in the City of London, Engineer, and JoHN
INGLIS, of Ellesmere Road, Old Ford, in the County of Middlesex, Engineer, 2
send greeting.
WHEREAS. Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of October, in the year of our Lord
One thousand.eight. hundred and sixty-three, in the twenty-seventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto.
us, the said Arthur Kinder and John Inglis, Her special license that we, the
said Arthur Kinder and John Inglis, our executors, administrators, and
assigns, or such others as we, the said Arthur Kinder and John, Inglis,
our executors, administrators, or assigns, should at any time agree with,

page_text: 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 THE MANU-
FACTURE OF METALLIC FOILS AND IN THE APPARATUS TO BE EMPLOYED THEREIN," upon
the condition (amongst others) that we, the said Arthur Kinder and John
Inglis, our executors or administrators, by an instrument in writing under
our hands and seals, or under the hand and seal of one of us or them, should
particularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the samo to be filed
in the Great Seal Patent Offico within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Arthur Kinder and John Inglis, do hereby
declare the nature of our said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement, reference being had to the accompanying Drawings, and
to the letters and figures marked thereon, that is to say :-
.
Our said Invention relates to a mode of treating foils, particularly lead and
tin, and alloys of lead and tin, during the operation of rolling, and consists in
coating or covering the surfaces of the sheets or bands when being piled into
the pack for rolling with oily, fatty, or saponaceous matter in substitution for
the French chalk or substances hitherto employed in the process of rolling the
packs, it having been found that the use of fatty or saponaceous matter will
enable the pack to be drawn to a considerably greater extent witliout requiring
the pack to be opened, thus effecting a considerable economy of time and
labor. In applying the oily, fatty, or saponaceous matter to the surface of
cach sheet or band by hand, I propose to employ a pad or rubber,.somewhat
similar to the pads or rubbers employed for French polishing, whereby a very
thin coating can be readily employed to the entire surface of the sheet. If
preferred the coating may be applied in the breaking down rolling mill by
causing the band or sheet as it leaves the breaking down rolls to pass Between
a pair of felt rolls, one of which may be made to rotate a little faster than
the other, so as to sleek or rub the surface of the sheet or band. This roller
is supplied with oily, fatty, or saponaceous matter by means of a small
perforated roller rotating in contact with the sleeking roller, such small roller
containing a sponge or or other absorbent material filled with the substance
to be used in the intérior thereof; which may be readily compressed so as to
cause the matter to exude through the small roller and be applied to the

page_text: surface of the sleeking. roer which lays it evenly over the surface of the sheet
or band..
And in order that our said Invention may be fully understood we shall now
proceed more particularly to describe the same, and for that purpose
we shall refer to the several Figures on the Sheet of Drawings hereunto
annexed,. the same letters of reference indicating corresponding parts in both
the Figures.
Figure represents a vertical transverse section of the several rolls; A
and A are the two metal rolls, a pulley on the upper one A driving by means
of a belt the spreading roll: B; the surface velocity of which is considerably in
excess of the surfaco velocity of the metal rolls A, A¹.. The roll B in con-
nected with the corresponding roll B' by the gearing D, D, shewn in Figure 2.
Both of these rolls are covered with felt or other soft material; and the upper
one B revolves in contact with the composition roll C shewn in Figures 1 and 2.
E is a sponge contained inside the composition roll which is charged with fatty
or saponaceous matter and is capable of compression from outside the roll by
the screws F, F, and internal discs or pistons, as shewn clearly in Figure 2.
This compression of the sponge causes the fatty or saponaceous matter
to exude through perforations in the body of the roll C and to charge
the surface of the felt covering of the roll B; G is the gathering roll
drawn by a belt from the metal' roll A, and upon which the foil is
wound.
.The following is the action of the apparatus:-The sheet of metall II, after
passing through the finishing rolls A, A, is introduced between the spreading
rolls B B travelling at a different speed to the surface of the sheet, and as
these rolls are charged with the fatty or saponaceous matter and kept in close
contact with the metal H they deposit an even coating of the said matter
thereon, and the metal thus coated may either be coiled on the gathering
roll G, or cut into lengths reading for finishing as preferred.
Having now described and particularly ascertained the nature of our said
Invention, and the manner in which the same is or may be used or carried into
effect, we would observe in conclusion that what we consider to be novel and
original, and therefore claim as the Invention secured to us by the herein-before
in part recited Letters Patent, is,-
1st, the coating or covering of the surface or surfaces of sheets or bands
of soft metal or alloys intended to be piled into a pack for rolling with oily,
fatty, or saponaceous matter for the purpose herein-before described.
2nd, the peculiar. arrangement of machinery. or apparatus for coating, or

page_text: covering sheets or bands of soft metal or alloys with oily, fatty, or saponaceous
matters, as and for the purpose herein-before described.
In witness whereof, I, the said Arthur Kinder, on behalf of myself
and the said John Inglis, have hereunto set my hand and seal, this
Twenty-second day of April, in the year of our Lord One thousand
eight hundred and sixty-four.
ARTHUR KINDER. (L.S.)
