AN IMPROVED ARRANGEMENT OF PROJECTIONS FOR OBTAINING PROVISIONAL SPECIFICATION
Year: 1881

page_text: LETTERS PATENT to Samuel Chandler and Josiah Chandler, both of
104, Newington Causeway, in the County of Surrey, Gas Engineers, for an
Invention of "AN IMPROVED ARRANGEMENT OF PROJECTIONS FOR OBTAINING
PROVISIONAL SPECIFICATION left by the said Samuel Chandler and
Josiah Chandler at the Office of the Commissioners of Patents on the 13th
May 1881.
SAMUEL CHANDLER and JOSIAH CHANDLER, both of 104, Newington Causeway,
in the County of Surrey, Gas Engineers. "AN IMPROVED ARRANGEMENT OF
PROJECTIONS FOR OBTAINING SPACES IN APPARATUS USED IN THE MANUFACTURE
OF GAS."
This Invention has for its object the better and more accurate maintenance of
spaces or channels between sheets of iron, or clusters of such material which are
used in the purification of gas from ammonia and other impurities, and between
which spaces or channels the gas to be purified has to pass, and consists of stamping
sheets of iron on both sides in such a manner so that one projection shall rest upon
another; say, for example, that each projection is raised one eighth of an inch, it is
obvious a space of a quarter inch would be formed by two sheets coming together,
dimple upon dimple.
Sheets or clusters so arranged would form well regulated spaces or channels to
be used in the purification of gas, and applicable to washers and scrubbers.

SAMUEL CHANDLER and JOSIAH CHANDLER, both of 104, Newington Causeway,
in the County of Surrey, Gas Engineers. "AN IMPROVED ARRANGEMENT OF
PROJECTIONS FOR OBTAINING SPACES IN APPARATUS USED IN THE MANUFACTURE
OF GAS."
This Invention has for its object the better and more accurate maintenance of
spaces or channels between sheets of iron, or clusters of such material which are
used in the purification of gas from ammonia and other impurities, and between
which spaces or channels the gas to be purified has to pass, and consists of stamping
sheets of iron on both sides in such a manner that one projection shall rest upon
another; say, for example, that each projection is raised one eighth of an inch, it is
obvious a space of a quarter inch would be formed by two sheets coming together,
dimple upon dimple.
Sheets or clusters so arranged would form well regulated spaces or channels to
be used in the purification of gas, and applied to washers and scrubbers.
In order that our Invention should be better understood, we now refer to the
Drawings accompanying this Specification.
The letter A, Figure 1, shews a plan of a segment of sheet iron with our
improved projections applied, and which are marked C and D; we also shew a
section of the plate, Figure 2, with the indentations or projections lettered C and D,
where it will be seen that the sheet is stamped on both its sides, and in such a
manner that the indented dimple C rests against the raised dimple D of a sheet
similarly made, and a space is formed between the two sheets, just double the
distance of each projection or indentation. Any number of these sheets may be
placed together to form clusters, although we have shewn but four at Figure 2,
simply to make known the way we propose to apply them.
Having thus described the nature of our Invention and the manner in which it
is applied, we in conclusion wish it to be understood that what we claim as our
Invention is, stamping, indenting, or making protrusions on both sides of iron
sheets in such a manner as each rests upon the other, and forming spaces between
such sheets for the passage of the gas about double the distance of each indentation
or protrusion.
In witness whereof, I, the said Samuel Chandler, have hereunto set my hand
and seal, this Twelfth day of November, in the year of our Lord One
thousand eight hundred and eighty-one.
S. CHANDLER. (L.S.)
