Year: 1868

page_text: LETTERS PATENT to Daniel Spill, of Paradise Terrace, Hackney, in
the County of Middlesex, for the Invention of "IMPROVEMENTS
THE PRODUCTION OF COMPOUNDS CONTAINING XYLOIDINE."
Sealed the 22nd May 1869, and dated the 31st December 1868.
PROVISIONAL SPECIFICATION left by the said Daniel Spill at the
Office of the Commissioners of Patents, with his Petition, on the
31st December 1868.
I, DANIEL SPILL, of Paradise Terrace, Hackney, in the County of
Middlesex, do hereby declare the nature of my said Invention for
"IMPROVEMENTS IN THE PRODUCTION OF COMPOUNDS CONTAINING XYLOIDINE," to
be as follows:-
This Invention relates to the production of materials or compounds
containing xyloidine, and consists in the admixture of xyloidine or that
product which results from the action of a mixture of sulphuric and
nitric acids upon ligneous or vegetable fibre with animal, fish, vegetable;

page_text: or mineral oils, such for example as lard oil, cod liver oil, linseed oil,
or heavy coal oils, or with mixtures of the same together with the
admixture of other ingredients, such as paraffine, camphor, rosin, fat,
wax, india-rubber, gutta percha, or balata gum, or mixtures of the same,
so as to produce a material or materials which may be employed either
alone or in conjunction with pigments or other inert bodies for the pro-
duction of a compound which may be applied for useful purposes in the
arts, such for example as for the coating or the protecting of telegraph
wires which have or which have not been previously coated or protected,
for moulding into forms, or for rolling into sheets or otherwise, for
spreading either upon fabrics or otherwise, or for the coating of metals
or wood.
In carrying out my Invention I prefer, first, to dissolve in one or
more of the before-mentioned oils one or more of the ingredients pre-
viously mentioned, such for example as camphor or rosin. This I prefer
to effect at an elevated temperature. The solution thus resulting is a
solvent of xyloidine, and I employ it for the purpose of dissolving the
xyloidine. The xyloidine is by preference previously dried or deprived
by any of the well-known methods of any adhering moisture, and then
the incorporation with or the solution in the before-mentioned solvent
may be effected at the ordinary or at an clevated temperature. The
mixture or compound thus resulting is then masticated either by the
employment of rolls or cylinders or otherwise by preference with the
application of heat, as is well understood. The product thus obtained
may either be employed direct or it may be further incorporated with
pigments or with metallic, mincral, vegetable, or fibrous materials as
diluents.
The consistency of the material will be dependent on the proportions
of the several ingredients employed, thus, for example, when I wish to
obtain a material suitable for the covering or protecting of telegraph
wires, or for moulding, rolling, or spreading, I have found that the
several materials employed in about the following proportions, videlicit,-
Camphor
20 parts by weight.
Oil, such for example as linseed oil - 40

possess greater flexibility or greater fluidity then I increase the proportion
of oil or oils until the desired properties are obtained.
SPECIFICATION in pursuance of the conditions of the Letters l'atent,
filed by the said Daniel Spill in the Great Seal l'atent Office on
the 30th June 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, 1, DANIEL
SPILL, of Paradise Terrace, Hackney, in the County of Middlesex, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirty-first day of December, in the
year of our Lord One thousand eight hundred and sixty-eight, in the
thirty-second year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Daniel Spill, Her special
license that I, the said Daniel Spill, my executors, administrators, and
assigns, or such other as I, the said Daniel Spill, my executors, adminis-
trators, or 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 THE PRO-
DUCTION OF COMPOUNDS CONTAINING XYLOIDINE," upon the conditions (amongst
others) that I, the said Daniel Spill, my executors or administrators, by
an instrument in writing under my hand and seal, 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 be filed
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Daniel Spill, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement, that is to say:-
This Invention relates to the production of materials or compounds
containing xyloidine, and consists in the admixture of xyloidine (or that

page_text: product which results from the action of a mixture of sulphuric and
nitric acids upon ligneous or vegetable fibre) with animal, fish, vegetable,
or mineral oils, oxidized or otherwise, such for example as vegetable or
mineral tar, lard oil, cod liver oil, camphor oil or liquid camphor, linseed
oil, or heavy coal oils, or with mixtures of the same, together with the
admixture of other ingredients, such as paraffine, camphor, resins, fat,
wax, india-rubber, gutta percha, or balata gum, or mixtures of the same,
so as to produce a material or materials which may be employed either
alone or in conjunction with pigments or other inert bodies for the
production of a compound which may be applied for useful purposes in
the arts, such for example as for moulding into forms, such as dishes,
bowls, tubing, covering telegraph wire, or for rolling into sheets or
otherwise for spreading either upon or between fabrics or otherwise,
or for the coating or for the preservation of metals, wood, and other
bodies.
In carrying out my Invention I prefer, first, to combine or dissolve in
one or more of the before-mentioned oils one or more of the ingredients
previously mentioned, such for example as camphor, camphor oil or
liquid camphor in which camphor has or has not been dissolved. This
I prefer to effect at an elevated temperature, and the solution thus
resulting is a solvent of xyloidine, and I employ it for the purpose of
dissolving xyloidine. The xyloidine is by preference previously dried
or deprived by any of the well-known methods of any adhering aqueous
moisture, and then the incorporation with the before-mentioned solvent
may be effected at the ordinary or at an elevated temperature. The
mixture or compound thus resulting is then masticated either by the
employment of rolls or masticators such as are employed in the pre-
paration of gutta perclia or india-rubber, or otherwise by preference
with the application of heat, as is well understood. The product thus
obtained may either be employed direct or it may be further incorporated
with pigments, or with metallic, mineral, vegetable, or fibrous materials
as diluents.
The consistency of the material will be dependent on the proportions
of the several ingredients employed, thus, for example, when I wish to
obtain a material suitable for the covering or protecting of telegraph 35
wires, for making tubing, or for moulding, rolling, or spreading, I

page_text: have found that the several materials employed in about the following
proportions, videlecit,-
-
Camphor, camphor oil, or liquid camphor 20 parts by weight.
Oil, such for example as castor or linseed
oil, either before or after such oils have
been oxidized or boiled-
Xyloidine (soluble)

will give good results, but these proportions and the several ingredients
will vary according to the purposes to which it is intended the material
shall be applied. When it is desired to obtain a material which shall
posses greater or less flexibility, or greater or less fluidity, then I
increase or decrease the proportion or character of oil or oils until the
desired properties are obtained. When it is desired to produce a rigid or
hard material which shall contain a large proportion of oil I prefer then
to employ oils which will themselves undergo a hardening process. by
exposure to the air, or oils which have been previously submitted to an
oxidizing process, or which have been converted or transformed into a
semi-solid or thickened mass by means which are well understood.
When it is desired to produce a material of which gutta percha shall
form one of the ingredients, the gutta percha may be first subjected to
the solvent or softening action of the ingredients to be employed, as
herein-before mentioned, or the gutta percha may be softened by heat
and then be incorporated with the other ingredients.
Having now described and particularly ascertained the nature of my
said Invention, and the manner in which the same is or may be used or
carried into effect, I would observe in conclusion that what I consider to
be novel and original, and therefore claim as the Invention secured to
me by the herein-before in part recited Letters Patent is, the production
of compounds of xyloidine by the employment of non-volatile solvents,
in the manner and for the purpose herein-before described.
In witness whereof, I, the said Daniel Spill, have to this my
Specification set my hand and seal, the Twenty-sixth day of
June One thousand eight hundred and sixty-nine.
DANIEL SPILL. (L.s.)
