THE MANUFACTURE OF A NEW OR IMPROVED SUBSTITUTE FOR LETTERS PAT FOR GUMS AND RESINS, AND OF A MATERIAL SUITABLE FOR LUBRICATING AND OTHER PURPOSES."
Year: 1880

page_text: LETTERS PATENT to Charles Estcourt, F.C.S., of Manchester, and Frederick
Charles Eastwood, of Heaton-Chapel, both in the County of Lancaster, for an
Invention of "THE MANUFACTURE OF A NEW OR IMPROVED SUBSTITUTE FOR
LETTERS PATENT to Charles Estcourt, F.C.S., of Manchester, and Frederick
Charles Eastwood, of Heaton-Chapel, both in the County of Lancaster, for an
Invention of "THE MANUFACTURE OF A NEW OR IMPROVED SUBSTITUTE FOR
GUMS AND RESINS, AND OF A MATERIAL SUITABLE FOR LUBRICATING AND
OTHER PURPOSES."
PROVISIONAL SPECIFICATION left by the said Charles Estcourt and
Frederick Charles Eastwood at the Office of the Commissioners of Patents on
the 24th December 1880.
CHARLES ESTCOURT, F.C.S., of Manchester, and FREDERICK CHARLES EASTWOOD,
of Heaton-Chapel, both in the County of Lancaster. "THE MANUFACTURE OF A
NEW OR IMPROVED SUBSTITUTE FOR GUMS AND RESINS, AND OF A MATERIAL
SUITABLE FOR LUBRICATING AND OTHER PURPOSES."
This Invention relates to the treatment of the residue from the distillation of
hydro carbon oils, known as mineral oils (which name includes all petroleum oils,
paraffin oils, shale oils), vapourising above 212° Farenheit, with chemical substances
which give up oxygen readily under proper conditions, such as the salts known as
permanganates, chromates, bichromates, chlorates, nitrates, acted on by acids, or
the acids which are combined in these compounds, or mixtures of the aforesaid.
We thus produce varying quantities of a solid matter, which we use to replace
gums and resins and for other purposes, and also produce an oily matter which may
be used for lubricating or other purposes.
The best compound for the purpose is nitric acid, with or without heat. The
proportions vary from 20 to 90 parts of acid to 100 parts of residue. If any other
oxidising agent is used the proportions must be calculated from its chemical
equivalent in like proportions as with nitric acid.

the said Charles Estcourt and Frederick Charles Eastwood in the Great Seal
Patent Office on the 24th June 1881.
CHARLES ESCOURT, F.C.S., of Manchester, and FREDERICK CHARLES EASTWOOD,
of Heaton Chapel, both in the County of Lancaster. "THE MANUFACTURE OF A
NEW OR IMPROVED SUBSTITUTE FOR GUMS AND RESINS, AND OF A MATERIAL
SUITABLE FOR LUBRICATING AND OTHER PURPOSES."
This Invention relates to the treatment of the residues vapourising above 212°
Farenheit from the distillation of hydro-carbon oils known as mineral oils (which
name includes all petroleum oils, paraffin oils, shale oils), with chemical substances
which give up oxygen readily under proper conditions, such as the salts known as
permanganates, chromates, bi-chromates, chlorates, nitrates, acted on by acids, or
the acids which are combined in these compounds or mixtures of the aforesaid.
We thus produce varying quantities of a solid matter, which we use to replace
gums and resins and for other purposes, and also produce an oily matter, which
may be used for lubricating or other purposes.
The best compound for the purpose is nitric acid, with or without heat. The
proportions vary from 80 to 90 parts of acid to 100 parts of residue. If any other
oxidysing agent is used the proportions must be calculated from its chemical
equivalent in like proportions as with nitric acid.
Having thus particularly described and ascertained the nature of this our said
Invention, together with the best methods with which we are acquainted for
carrying the same into practical effect, we wish it to be understood that what we
claim and desire to secure by Letters Patent is,―
The production of a compound to be used as a substitute for gums and resins
and for other purposes, and of a material suitable for lubricating or other purposes,
substantially as hereiubefore described.
In witness whereof, I, the said Frederick Charles Eastwood, on behalf of the
said Charles Ecourt and myself, have hereunto set my hand and seal, this
Twenty third day of June, in the year of our Lord One thousand eight
hundred and eighty one.
