IMPROVED MEANS OR APPARATUS FOR TREATING AND UTILIZING GAS TAR FOR HEATING PURPOSES." PROVISIONAL SPECIFICATION
Year: 1873

page_text: LETTERS PATENT to Joe Green Hey, of Hartshead Moor, Cleckheaton,
in the County of York, India-rubber Manufacturer, and Richard
Sugden, of Brighouse, in the County aforesaid, Corn Miller, for the
Invention of "IMPROVED MEANS OR APPARATUS FOR TREATING AND
UTILIZING GAS TAR FOR HEATING PURPOSES."
PROVISIONAL SPECIFICATION left by the said Joe Green Hey and
Richard Sugden at the Office of the Commissioners of Patents, with
their Petition, on the 7th April 1873.
We, JOE GREEN HEY, of Hartshead Moor, Cleckheaton, in the County
of York, India-rubber Manufacturer, and RICHARD SUGDEN, of Brig-
house, in the County aforesaid, Corn Miller, do hereby declare the nature
of the said Invention for "IMPROVED MEANS OR APPARATUS FOR TREATING
AND UTILIZING GAS TAR POR HEATING PURPOSES," (to be as follows) :-
-
This Invention has for its object the treating and utilizing crude or
raw gas tar for the purpose of heating steam boilers and other like uses.

page_text: Tar, when applied to the furnaces of steam boilers, in its crude state
runs between the grate bars, a large per-centage being wasted, and like-
wise gives off dense smoke, which objections have heretofore rendered
this material of little or no use for heating purposes.
The objections we remedy as follows:-The tar is deposited in a still,
to which we apply a steam pipe. The heat of the steam renders the tar
sufficiently limpid that it readily flows from the still into a pipe to which
a second pipe supplied with steam is connected, the pressure of steam
forcing or discharging the liquid tar in the form of a spray or gas,
whereon it is fired. On the bars we deposit chalk stone for retaining
heat.
In some cases we add to the tar in the still common soda, lime water,
and ammonia water in about the following proportions :-To one ton of
tar, one-tenth common soda, one-tenth lime water, one-tenth ammonia
water. The naptha contained in the tar may be burnt therewith, or may
be separated by the still being provided with vapour pipe and worm of
ordinary construction for condensation.
SPECIFICATION filed in pursuance of the conditions of the Letters
Patent, and of an Order of the Lord Chancellor, by the said Joe
Green Hey and Richard Sugden in the Great Seal Patent Office on:
the 13th October 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOE
GREEN HEY, of Hartshead Moor, Cleckheaton, in the County of York,
India-rubber Manufacturer, and RICHARD SUGDEN, of Brighouse, in the
County aforesaid, Corn Miller, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventh day of April, in the year
of our Lord One thousand eight hundred and seventy-three, in
the thirty-sixth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto us, the said Joe Green Hey and Richard &
Sugden, Her special licence that we, the said Joe Green Hey and Richard
Sugden, our executors, administrators, and assigns, or such others as we,
the said Joe Green Hey and Richard Sugden, our executors, administra-

page_text: tors, and 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 "IMPROVED MEANS OR APPARATUS FOR
TREATING AND UTILIZING GAS TAR FOR HEATING PURPOSES," upon the con-
dition (amongst others) that we, the said Joe Green Hey and Richard
Sugden, our exécutors or administrators, by an instrument in writing
under our, or their, or one of their hands and seals, 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 on or before the Fourteenth day of October,
1873.
NOW KNOW YE, that we, the said Joe Green Hey and Richard Sugden,
do hereby declare the nature of our 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 has for its object the treating and utilizing crude or
raw gas tar for the purpose of heating steam boilers and other like uses.
Tar, when applied to the furnaces of steam boilers, in its crude state
runs between the grate bars, a large per-centage being wasted, and like-
wise gives off dense smoke, which objections have heretefore rendered
this material of little or no use for heating purposes.
The objections we remedy as follows:-The tar is deposited in a still
or other vessel to which we apply a steam pipe. The heat of the steam
renders the tar sufficiently limpid that it readily flows from the still or
vessel into a pipe to which a second pipe supplied with steam is con-
nected, the pressure of steam forcing or discharging the liquid tar in the
form of a spray or gas upon the fire, whereon it is fired or ignited. On
the bars we deposit chalk stone, limestone, coal, or coke for retaining
heat.
In some cases we add to the tar in the still or vessel common soda,
lime water, and ammonia water, by preference in about the following
proportions-To one ton of tar, about one-tenth common soda, one-
tenth lime water, one-tenth ammonia water; but we may use these or
any of them in any other desirable quantities; or we may add creosote

page_text: or other hydrocarbon oils. The naptha contained in the tar may be
burnt therewith, or may be separated by the still being provided with
vapour pipe and worm of ordinary construction for condensation.
In witness whereof, I, the said Joe Green Hey, for and on behalf
of myself and the said Richard Sugden, have hereunto set my
hand and seal, this Fourth day of October, in the year of our
Lord One thousand eight hundred and seventy-three.
