Year: 1869

page_text: LETTERS PATENT to Daniel Spill, of Paradise Terrace, Hackney, in
the County of Middlesex, for the Invention of "IMPROVEMENTS IN
THE PREPARATION AND USE OF SOLVENTS OF XYLOIDINE SO AS TO RENDER
Scaled the 19th April 1870, and dated the 26th October 1869.
PROVISIONAL SPECIFICATION left by the said Daniel Spill at the
Office of the Commissioners of Patents, with his Petition, on the
26th October 1869.
I, DANIEL SPILL, of Paradise Terrace, Hackney, in the County of
Middlesex, do hereby declare the nature of my said Invention for "Ix-
PROVEMENTS IN THE PREPARATION AND USE OF SOLVENTS OF XYLOIDINE 80 AS TO
RENDER THE SAME MORE SUITABLE FOR INDUSTRIAL APPLICATIONS," to be as
follows:-
This Invention relates to the preparation and use of certain solvents
of xyloidine, and which differ from the ordinary or known solvents
of xyloidine in that these menstrua which are employed are not
necessarily in themselves solvents of xyloidine, but become so by the
addition of the bodies, compounds, or substances herein referred to.
[Price S1

page_text: The solvents amongst other applications may be employed in conjunction
with my Invention for improvements in compounds containing xyloidine
in those processes which are described in Letters Patent granted to me
on the 31st December 1868, numbered 3984, and as substitutes for the
non-volatile solvents therein described.
And this Invention consists in the employment,--
First. Of camphor or of camphor oil or mixtures of the same in
conjunction with hydrocarbons, or of such volatile products as exist in
or are obtained from the distillation of petroleum, or the volatile pro-
ducts obtained by the distillation of the residual products resulting from
the distillation of coal, shale, or other bituminous substances, and which
volatile products have a boiling point or boiling points from about 220°
to about 400° Fahrenheit, the same to be employed in about equal
proportions.
Second. Of camphor or camphor oil, or mixtures of the same in
conjunction with alcohol or spirits of wine, the same to be employed in
about equal proportions.
Third. Of hydrocarbons having a boiling point ranging from 220° to
400° Fahrenheit, in conjunction with alcohol or spirits of wine in about
equal proportions.
Fourth. Of castor oil, of camphor or of camphor oil, or of mixtures of
the same in conjunction with alcohol or spirits of wine, in about equal
proportions.
Fifth. Of the admixture of camphor or of camphor oil, or mixtures of
the same with hydrocarbons, such as before referred to in conjunction
with alcohol or spirits of wine, all in about the same proportions, and
the employment of the same either as a simple admixture or by
preférence of the distillate of such mixture.
Sixth. Of the admixture of camphor or of camphor oil or mixtures of
the same with bi-sulphide of carbon in conjunction with alcohol or
spirits of wine, all in about the same proportions, and the employment
of the same either as a simple admixture, or by preference of the
distillate of such mixture.
Seventh. Aldehyde, either alone or in conjunction with alcohol or
spirits of wine in about equal proportions, and the employment of the
same, either as a simple admixture, or by preference of the distillate
of such mixture,

page_text: Eighth. Of the employment of any two or more of any of the before-
mentioned solvents, either in the proportion of about equal parts or in
other proportions.
In all of those instances in which the word alcohol is mentioned it is
to be understood that methylated spirit may be substituted.
According to one method of applying my Invention I dissolve the
xyloidine in any of the before-mentioned solvents or mixtures of the
same, and then incorporate the solution of or the softened xyloidine with
animal, fish, vegetable, or mineral oils oxidised or otherwise, such for
example, as lard, oil, cod liver oil, castor oil, tar 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, 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 or compounds which may be
applied for useful purposes in the arts. The xyloidine may be dissolved
while in a hydrated condition, but it is by preference to be previously
dried or deprived of moisture by any of the well known methods.
The consistency of the product 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, viz.
Xyloidine
27 parts by weight.
0
When it is desired to obtain a material which shall possess greater or
less flexibility or greater or less fluidity, then I increase or decrease the
proportion or character of the oil or oils until the desired properties are
obtained

filed by the said Daniel Spill in the Great Seal Patent Office on
the 26th April 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, 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 Twenty-sixth day of October, in the
year of our Lord One thousand eight hundred and sixty-nine, in the
thirty-third year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Daniel Spill, Her special licence, that
I, the said Daniel Spill, my executors, administrators, and assigns, or
such others as 1, the said Daniel Spill, my executors, administrators,
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 PREPARATION
AND USE OF SOLVENTS OF XYLOIDINE SO AS TO RENDER THE SAME MORE SUITABLE
FOR INDUSTRIAL APPLICATIONS," upon the condition (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 preparation and use of certain solvents
of xyloidine, and which differ from the ordinary or known solvents
of xyloidine, in that these menstrua which are employed are not
necessarily in themselves solvents of xyloidine, but become so by the
addition of the bodies, compounds, or substances herein referred to.
The solvents amongst other applications may be employed in conjunction

page_text: with my Invention for improvements in compounds containing xyloidine
in those processes which are described in Letters Patent granted to me
on the Thirty-first December One thousand eight hundred and sixty-
eight, No. 3984, and as substitutes for the non-volatile solvents therein
described.
And this Invention consists in the employment,-
First. Of camphor or of camphor oil, or of mixtures of the same in
conjunction with hydrocarbons, or of such volatile products as exist in or
are obtained from the distillation of petroleum or the volatile products
obtained by the distillation of the residual products resulting from the
distillation of coal, shale, or other bituminous substances, and which
volatile products have a boiling point or boiling points from about two
hundred and twenty degrees to about four hundred degrees Fahrenheit,
the same to be employed in about equal proportions.
Second. Of camphor or camphor oil, or mixtures of the same in
conjunction with alcohol or spirits of wine, the same to be employed
in about equal proportions.
Third. Of hydrocarbons having a boiling point ranging from two
hundred and twenty degrees to four hundred degrees Fahrenheit, in
conjunction with alcohol or spirits of wine in about equal proportions.
Fourth. Of castor oil, of camphor or camphor oil, or of mixtures of
the same in conjunction with alcohol or spirits of wine in about equal
proportions.
Fifth. Of the admixture of camphor or of camphor oil, or mixtures of
the same with hydrocarbons, such as before referred to in conjunction
with alcohol or spirits of wine, all in about the same proportions, and the
employment of the same, either as a simple admixture, or by preference
of the distillate of such mixture.
Sixth. Of the admixture of camphor or of camphor oil, or mixtures of
the same with bi-sulphide of carbon in conjunction with alcohol or
spirits of wine, all in about the same proportions, and the employment
of the same either as a simple admixture, or by preference of the
distillate of such mixture.
Seventh. Aldehyde, either alone or in conjunction with alcohol or
spirits of wine in about equal proportions, and the employment of the
same either as a simple admixture, or by preference of the distillate of
such mixture.

page_text: Eighth. Of the employment of any two or more of any of the before-
mentioned solvents, either in the proportion of about equal parts, or in
other proportions.
In all of those instances in which the word alcohol is mentioned it is
to be understood that methylated spirit may be substituted for the same.
According to one method of applying my Invention I dissolve the
xyloidine in any of the before-mentioned solvents or mixtures of the
same, and then incorporate the solution with animal, fish, vegetable, or
mineral oils, oxidised or otherwise, such for example as lard oil, cod
liver oil, castor oil, tar oil, or heavy coal oils, or with mixtures of the
same together with the admixture of other ingredients such as paraflin,
camphor, resins, fat, wax, 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 or compounds which may be applied for useful purposes
in the arts. Or instead of effecting the solution of the xyloidine, the
xyloidine may be so acted upon by the before-mentioned solvents as
that it may be converted into a softened condition, and the softened
xyloidine may then be incorporated with the substances before
mentioned, and be manipulated and applied as before described. The
xyloidine may be dissolved when in a hydrated condition, but it is
by preference to be previously dried or deprived of moisture by any
of the well known methods.
The consistency of the product 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 will give
good results, viz.:-
Xyloidine
-
27 parts by weight.

page_text: less flexibility or greater or less fluidity, then 1 increase or decrease the
proportion or character of the oil or oils until the desired properties are
obtained.
What I claim is the preparation and use of the before-mentioned
solvents of xyloidine, in the manner and for the purposes herein-before
described.
In witness whereof, I, the said Daniel Spill, have to this my Speci-
fication set my hand and seal, the Twenty-second day of April
One thousand eight hundred and seventy.
DANIEL SPILL. (L.S.)
