IMPROVEMENTS IN AND APPARATUS FOR THE MANUFACTURE OF CHARCOAL OR PRODUCTS SUITABLE FOR USE AS FILTERING MEDIA, AND FOR OTHER PURPOSES."
Year: 1879

page_text: LETTERS PATENT to Robert Weare, of the City of Manchester, in the
County of Lancaster, Sanitary Engineer, for the Invention of "IMPROVEMENTS
IN AND APPARATUS FOR THE MANUFACTURE OF CHARCOAL OR PRODUCTS
SUITABLE FOR USE AS FILTERING MEDIA, AND FOR OTHER PURPOSES."
PROVISIONAL SPECIFICATION left by the said Robert Weare at the Office
of the Commissioners of Patents on the 26th September 1879.
ROBERT WEARE, of the City of Manchester, in the County of Lancaster, Sanitary
Engineer. "IMPROVEMENTS IN AND APPARATUS FOR THE MANUFACTURE OF
CHARCOAL OR PRODUCTS SUITABLE FOR USE AS FILTERING MEDIA, AND FOR OTHER
PURPOSES."
I take sewage, night soil, focal matters, excrement, garbage, and refuse from
ashpits and markets, and carbonise the same as hereinafter described, and thus
produce charcoal or carbonaceous products suitable for being used as filtering
media, and for mixing with other materials in the manufacture of manure.
To this end I place the materials indicated above in a retort or vessel which can
be closed, and I heat such retort or vessel until the contents are charred or
carbonised; the gases and vapours generated being, by preference, burnt in the
furnace which is used to heat the retort or vessel.
In the apparatus which I consider to be the most suitable for carrying my
Invention into effect I employ a retort, by preference of a cylindrical form, and
constructed of hoematite iron, which is not liable to bag or belly when heated to
the required temperature, but other suitable forms of carbonisers may be used in
the manner and for the purposes indicated. In the case of the retort being
arranged to revolve, I take off the gases and vapours by means of a pipe passing
through a stuffing box in one of the axes.
The products of the operation, which consist of animal, vegetable, and mineral
charcoal, are very suitable for use in the filtration of water, sewage, and other
fluids and semi-fluids, and may also be used with advantage to mix with sewage or
excreta, or with other matters which it is desirable to render inodorous and
innocuous and more suitable for transport, such mixtures constituting useful
manure.

an Order of the Lord Chancellor, filed by the said Robert Weare in the Great
Seal Patent Office on the 9th April 1880.
ROBERT WEARE, of the City of Manchester, in the County of Lancaster, Sanitary
Engineer. "IMPROVEMENTS IN AND APPARATUS FOR THE MANUFACTURE OF
CHARCOAL PRODUCTS SUITABLE FOR USE AS FILTERING MEDIA, AND FOR OTHER
PURPOSES."
I take sewage, night soil, fœcal matters, excrement, garbage, and refuse from
ashpits and markets, and carbonise the same as hereinafter described, and thus
produce charcoal or carbonaceous products suitable for being used as filtering
media, and for mixing with other materials in the manufacture of manure.
To this end I place such materials as indicated above in a retort or vessel which
can be closed, and I heat such retort or vessel until the contents are charred or
carbonised; the gases and vapours generated being, by preference, burnt in the
furnace which is used to heat the retort or vessel.
In the apparatus which I consider to be the most suitable for carrying my
Invention into effect I employ a retort, by preference of a cylindrical form, and
constructed of hematite iron, which is not liable to bag or belly when heated to
the required temperature, but other suitable forms of carbonisers may be used in
the manner and for the purposes indicated. In the case of the retort being
arranged to revolve I take off the gases and vapours by means of a pipe passing
through a stuffing box in one of the axes.
.The products of the operation, which consist of animal, vegetable, and mineral
charcoals, are very suitable for use in the filtration of water, sewage, and other
fluids and semi-fluids, and may also be used with advantage to mix with sewage
or excreta, or with other matters which it is desirable to render inodorous and
innocuous, and more suitable for transport, such mixtures constituting useful
manures.
Having thus particularly described and ascertained the nature of this my said
Invention, together with the best methods with which I am acquainted for carrying
the same into practical effect, I wish it to be understood that I do not confine
myself to the precise details herein before described, as the same may be considerably
varied without departing from the Invention, but that I claim, the improvements
in and apparatus for the manufacture of charcoals or carbonaceous products,
substantially as and for the purposes hereinbefore described.
In witness whereof, I, the said Robert Weare, have hereunto set my hand and
seal, this Twenty fourth day of March, in the year of our Lord 1880.
