IMPROVEMENTS IN SALINOMETERS
Year: 1863

page_text: LETTERS PATENT to James Burrell, of No. 85, Back Church Lane, White-
chapel, in the County of Middlesex, for the Invention of "IMPROVEMENTS
IN SALINOMETERS."
Sealed the 23rd October 1863, and dated the 9th May 1863.
PROVISIONAL SPECIFICATION left by the said James Burrell at the
Office of the Commissioners of Patents, with his Petition, on the
9th May 1863.
I, JAMES BURRELL, of No. 85, Back Church Lane, Whitechapel, in the
County of Middlesex, do hereby declare the nature of the Invention for
"IMPROVEMENTS IN SALINOMETERS," to be as follows:-
This Invention has for its object improvements in salinometers. For the
steam boilers of sea-going steam ships, in order to determine from time to time
the amount of salt contained in solution in the water in the boiler, I lead two
pipes, the one from the top and the other from the bottom of the boiler; these
pipes I connect with a glass tube, so that the said tube forms a connection
between the two pipes. The arrangement is thus very similar to the ordinary
water gauge of a steam boiler, but differs from it in the employment of a con-
siderable length of pipe above and below the glass tube. In the upper pipe
into which the steam from the boiler enters condensation is constantly going
on, and the water thus distilled runs down and fills the lower pipe. The water
stands in the glass tube as in an ordinary gauge tube, but its level will not
be the same as that in the boiler, for the weight of the salt water in the boiler.

page_text: will raise the column of distilled water in and below the glass tube to a height
considerably above its own level. An ordinary gauge tube gives the water
level of the boiler, and this when compared with that in the salinometer gauge
tube will indicate on a scale attached, or by reference to a table, the density
of the water in the boiler.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Burrell in the Great Seal Patent Office on the
9th November 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
BURRELL, of No. 85, Back Church Lane, Whitechapel, in the County of
Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of May, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-sixth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said James Burrell, Her special licence that I, the said
James Burrell, my executors, administrators, and assigns, or such others
as I, the said James Burrell, my executors, administrators, 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 of
"IMPROVEMENTS IN SALINOMETERS," upon the condition (amongst others) that
I, the said James Burrell, my executors or administrators, by an instrument in
writing under my, 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 within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said James Burrell, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say :-
This Invention has for its object improvements in salinometers. For the
steam boilers of sea-going steam ships, in order to determine from time to time
the amount of salt contained in solution in the water in the boiler, I lead two

page_text: my Invention, and in the same Figure a portion of a steam boiler is shown in
section; Figure 2 is a front view of a salinometer gauge tube with an ordinary
water gauge tube by the side of it.
a is a tube passing out of the steam space at the upper part of the boiler, its
end is covered with a perforated cup a', to prevent the entrance of water from
the boiler by priming; 6 is another pipe passing out of the lower part of the
boiler, and ascending on the outside of the boiler; it is fitted with a cock at b',
and the mouth of the pipe at b2 is curved downwards so as to prevent as much
as may be the admixture of the salt water in the boiler with the distilled
water in the pipe; c is a glass gauge tube, like an ordinary water tube,
fitted betweeen the pipes a and b, and furnished with cocks c¹ and c² as is
usual; is the ordinary water tube gauge alongside of the salinometer.
working the lower cock should be kept closed until it is desired to ascertain
the degree of saturation or salting of the water in the boiler. The steam in
the pipe a continues constantly to condense; furnishing pure water, until if it
be left a sufficient time it becomes full up to its mouth, there being then an
accumulation of pure water in the pipe a, if the cock 6' is partly opened, the
water will descend gradually until it becomes stationary some distance above
the water level in the water gauge tube, and the amount of this difference
In

page_text: being observed, an easy calculation or reference to a table prepared for the
instrument will as before mentioned give the density of the water in the
boiler.
In witness whereof, I, the said James Burrell, have hereunto set
my hand and seal, this Ninth day of November, in the year of our
Lord One thousand eight hundred and sixty-three.
JAMES BURRELL. (L.S.)
