page_text: LETTERS PATENT to William Payson Tilton, of New York, in the United States
of America, but now residing at No. 1, New Burlington Street, Regent Street,
in the County of Middlesex, for the Invention of "IMPROVEMENTS IN THE
PREPARATION OF MATTERS FOR USE IN PURIFYING SYRUPS, OILS, AND OTHER
LIQUIDS." A communication from abroad by George Williams Tilton, of New
York, in the United States of America.
PROVISIONAL SPECIFICATION left by the said William Payson Tilton at the
Office of the Commissioners of Patents on the 4th October 1876.
WILLIAM PAYSON TILTON, of New York, in the United States of America, but
now residing at No. 1, New Burlington Street, Regent Street, in the County of
Middlesex. "IMPROVEMENTS IN THE PREPARATION OF MATTERS FOR USE IN
PURIFYING SYRUPS, OILS, AND OTHER LIQUIDS." A communication from abroad
by George Williams Tilton, of New York, in the United States of America.
The Invention relates to the preparation of iron and other ore, fire or other hard
brick, oxide of manganese and other refractory substances for use in the purification
of syrups, oils, and other liquids requiring such treatment.
In carrying out the Invention the ore or other matter selected is first reduced by
crushing or otherwise to a granular condition, it is then sifted to remove from the
granules matter which has become reduced to a powdered state by the crushing in
order to facilitate the washing of the granules, and for the purpose of freeing them
of the more solvent particles combined with or adhering to them. These washed
granules are then saturated in a combination of coal tar and ammoniacal liquor of
gas works, the proportion of the coal tar being generally in excess of that of the
ammoniacal liquor; but such proportions may be varied. The matters thus
prepared are then placed in heated retorts which are then securely closed. These
retorts are each provided as in the case of gas retorts with a conduit pipe to convey
away the vapours generated, and conduct them into a reservoir, the lower or dipping
end of these conduit pipes being sealed to a considerable depth, say to not less
Din A31

page_text: than 17 inches for back pressure, and thereby to facilitate the incorporation of the
carbon.
The retorts are heated to a red heat before the matters are placed therein for
carbonization, but such temperature may be varied, and the heating is continued
until all the solvent properties have been evaporated and driven off from the
matters treated, and those matters have become thoroughly carbonized.
The thorough carbonization of the of the matters having been effected in a retort
the lid thereof is removed, the carbonized matter is raked out, and when cool is ready
for use in the purification of oil, syrup, or other liquid.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by the
said William Payson Tilton in the Great Seal Patent Office on the 28th March
1877.
WILLIAM PAYSON TILTON, of New York, in the United States of America, but
now residing at No. 1, New Burlington Street, Regent Street, in the County of
Middlesex, "IMPROVEMENTS IN THE PREPARATION OF MATTERS FOR USE IN
PURIFYING SYRUPS, OILS, AND OTHER LIQUIDS." A communication from abroad by
George Williams Tilton, of New York, in the United States of America.
The object of the Invention is to effect the purification of syrups, oils, and other
liquids, without the necessity for the use of bone charcoal or other matter dependent
for its action upon its acid or alkaline character.
The Invention relates to the preparation of iron and other ore, fire or other hard
brick, oxide of manganese, and other substances sufficiently refractory to resist the
action of the heat necessary to accomplish these results for use in the purification of
syrups, oils, and other liquids requiring such treatment.
In carrying out the Invention the ore or other matter selected is first reduced by
crushing or otherwise to a granular condition, it is then sifted to remove from the
granules matter which has become reduced to a powdered state by the crushing in
order to facilitate the washing of the granules; the granules are then washed for
the purpose of freeing them of the more solvent particles combined with or adhering
to them. These washed granules are then saturated in a combination of coal tar
and ammoniacal liquor of gas works, the proportion of the coal tar being generally
in excess of that of the ammoniacal liquor, but such proportions may be varied.
The matters thus prepared are then placed in heated retorts, which are then securely
closed. These retorts are each provided as in the case of gas retorts with a conduit
pipe to convey away the vapours and gases generated, and conduct them into a
reservoir, the lower or dipping end of these conduit pipes being sealed to a con-
siderable depth, say to not less than 17 inches for back pressure, and thereby to
facilitate the more effectual incorporation of the carbon as well as the conducting
away of the tarry matters precipitated into such reservoir.
The retorts are heated to just above a red heat before the matters are placed
therein for carbonization, but such temperature may be varied; the retorts are then
securely closed, and the heating is continued until all the solvent properties have
been evaporated or driven off from the matters treated and those matters have
become thoroughly carbonized.
The thorough carbonization of the matters having been effected in such retort the
lid thereof is removed, the carbonized matter is raked out into other vessels, and
when cool is ready for use in the purification of oil, syrup, or other liquid. This
carbonized matter may be placed in the ordinary tubes, such as are used in sugar
refineries, the filtration being performed in the same manner as when using bone
charcoal for the purpose.
Having thus described the Invention as communicated to me, I would have it
understood that what I claim is, the preparation of iron or other ore, fire or other

page_text: hard brick, oxide of manganese, or other sufficiently refractory substance for use in
the purification of syrups, oils, and and other liquids, substantially as explained.
In witness whereof, I, the said William Payson Tilton, have hereunto set my
hand and seal, this Thirteenth day of February, in the year of our Lord,
One thousand eight hundred and seventy-seven.
Witness,
