Road, in the County of Essex, Engineer, for the Invention of
" IMPROVEMENTS IN THE MANUFACTURE AND USE OF COMPOUNDS CONTAINING
SOLUBLE GUN COTTON, OR OF COMPOUNDS ANALOGOUS THERETO.'
"
Sealed the 7th September 1875, and dated the 4th June 1875.
PROVISIONAL SPECIFICATION left by the said Frederick Greening at
the Office of the Commissioners of Patents, with his Petition, on
the 4th June 1875.
I, FREDERICK GREENING, of Beaufoy Road, Plaistow Road, in the
County of Essex, Engineer, do hereby declare the nature of my said In-
vention for "IMPROVEMENTS IN THE MANUFACTURE AND USE OF COMPOUNDS
CONTAINING SOLUBLE GUN COTTON, OR OF COMPOUNDS ANALOGOUS THERETO," to be
as follows:
This Invention relates to the manufacture and use of compounds
capable of being employed for effecting the insulation of telegraph wires
or for other purposes, and consists in submitting mixtures of paraffin,
shellac, resin, or gum, such for example as copal, also of the residues

page_text: left after effecting the distillation of the heavier oils of tar or mixtures
of the same with soluble gun cotton, or with soluble compounds
analogous thereto, to the action of kreosote obtained from wood tar or
of mixtures of the same with other solvents of gun cotton, which at an
elevated temperature effects the combination or incorporation of the
materials before referred to, and thus converts them into a uniform
plastic condition, in which form the mass may be moulded into any
desired form, or be made to cover the wire or wires intended for tele-
graphic or other purposes, as is well understood. The material thus
obtained may be further employed in a manner similar to that now used
for the employment of india-rubber in and for the production of water-
proof fabrics or otherwise, and in the production of goods or of coated
fabrics capable of being employed for bookbinding, or as a substitute for
leather or for leather cloth, or for other purposes.
on the 3rd December 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
GREENING, of Beaufoy Road, Plaistow, in the County of Essex,
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of June, in the year
of our Lord One thousand eight hundred and seventy-five, in the 38th
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Frederick Greening, Her special license that
I, the said Frederick Greening, my executors, administrators, and
assigns, or such others as I, the said Frederick Greening, 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
MANUFACTURE AND USE OF COMPOUNDS CONTAINING SOLUBLE GUN COTTON, OR OF
COMPOUNDS ANALOGOUS THERETO," upon the condition (amongst others)

page_text: by an instrument т writing under my hand and seal, should par-
ticularly 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 Frederick Greening, 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 manufacture and use of compounds
capable of being employed for effecting the insulation of telegraph wires
or for other purposes, and consists in submitting mixtures of paraffin,
shellac, resin, or gum, such for example as copal, either alone or in
combination, and also of the residues left after effecting the distillation
of the heavier oils of tar, by preference those obtained from wood
tar, or mixtures of any two or more of the before-mentioned sub-
stances with soluble gun cotton, or with soluble compounds analagous
thereto, to the action of kreosote obtained from wood tar, or of those
products of distillation containing the same. These I employ together
with other solvents of soluble gun cotton, which at an elevated tempe-
rature effects the combination or incorporation of the materials before
referred to, and thus converts them into a uniform plastic condition, in
which condition the mass may be employed for purposes where pliability
is required, or which may be made to cover wire or wires for telegraphic
or other purposes. The compound or compounds thus obtained may be
employed as a substitute for and in a manner similar to that now
adopted for the employment of india-rubber in and for the production
of waterproof fabrics or for other purposes, and also in the production
of goods or of coated fabrics or materials, such coated fabrics or
materials being capable of being employed for bookbinding, or as a
substitute for leather or for leather cloth, or other similar purposes.
It will be evident that kreosote obtained from wood tar being a solvent
of soluble gum cotton and of paraffin, and also of the gums and other
substances before mentioned, it may be employed in conjunction with
any of the solvents of the same,

page_text: 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,―
First. The employment of what is known as kreosote, obtained from
the distillation of wood tar, as a solvent of soluble gun cotton, and also
of the several gums and substances herein-before mentioned in con-
junction with soluble gun cotton.
Second. The employment of such before-mentioned mixtures or com-
pounds for the purposes of insulation.
Third. The employment of such before-mentioned mixtures for water-
proofing or for other purposes where pliability is desired.
In witness whereof, I, the said Frederick Greening, have to this
my Specification set my hand and seal, this Third day of
December, One thousand eight hundred and seventy-five.
DTAT
FREDERICK GREENING.
