AN IMPROVEMENT APPLICABLE TO SALINOMETER CASES FOR STEAM BOILERS
Year: 1859

page_text: LETTERS PATENT to William Edward Newton, of the Office for Patents,
66, Chancery Lane, in, the County of Middlesex, Civil Engineer, for the
Invention of "AN IMPROVEMENT APPLICABLE TO SALINOMETER CASES FOR STEAM
BOILERS." A communication from abroad by Joseph Grice, of New York
City, in the United States of America.
PROVISIONAL SPECIFICATION left by the said William Edward Newton
at the Office of the Commissioners of Patents, with his Petition,
the 1st August 1859.
I, WILLIAM EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane,
in the County of Middlesex, Civil Engineer, do hereby declare the nature
of the said Invention for "AN IMPROVEMENT APPLICABLE TO SALINOMETER CASES
FOR STEAM BOILERS," to be as follows:-
.I.
This Invention of an improvement applicable to salinometer cases for steam
boilers consists in the employment, in combination with a salinometer case, of
a cylindrical or other conveniently shaped vessel so applied and provided with
passages that the water may pass through this additional vessel on its way
from the boiler to the salinometer case. By this means the water will be
prevented from arriving in the salinometer case in a state of ebullition, &,
therefore, its saltness can be accurately tested, and the liability to breakage of
the gauges is much reduced, and the danger of scalding the engineer entirely
obviated.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Edward Newton in the Great Seal Patent Office
on the 1st February 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the County
of Middlesex, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of August, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-third year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William Edward Newton, Her special license that I, the
said William Edward Newton, my executors, administrators, and assigns, or
such others as I, the said William Edward Newton, my executors, adminis-
trators, 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 King-
dom of Great Britain and Ireland, the Channel Islands, and Isle of Man,
an Invention for "AN IMPROVEMENT APPLICABLE TO SALINOMETER CASES FOR STEAM
BOILERS," being a communication from abroad by Joseph Grice, of New York,
in the United States of America, upon the condition (amongst others) that
I, the said William Edward Newton, by an instrument in writing under
my hand and seal, 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 William Edward Newton, do hereby
declare the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement, reference being had to the Drawing hereunto annexed,
and to the letters and figures marked thereon (that is to say) :—
"This Invention of an improvement applicable to salinometer cases for steam
boilers, consists in the employment, in combination with à salinometer case, of
a cylindrical or other conveniently shaped vessel so applied and provided withi
passages, that the water may pass through this additional vessel on its way
from the boiler to the salinometer case, and thereby be prevented from arriving
in the latter in a state of ebullition. The saltness of the water can by this

page_text: means be accurately tested, and the liability to breakage of the gauges is:
much reduced, and the danger of scalding the engineer entirely obviated.
In the accompanying Drawing, Fig. 1 is a side elevation of the salinometer
case with the improvement adapted thereto; Fig. 2 is a vertical section of
the same; Fig. 3 is a horizontal section of the same in the plane indicated
by the line, a, of Fig. 2. Similar letters of reference indicate corresponding
parts in all the Figures.
A is the upright cylindrical portion of the salinometer case in which the
salinometer or bydrometer B is placed to test or indicate the saltness of the
water. This case is also provided with grooves a, a, (Fig: 3,) to receive a
thermometer C. The bottom of the cylinder A is formed by part of a metal
passage box D, which also forms the bottom of the vessel E, which constitutes
the principal portion of the Invention. This vessel E consists of an upright
cylinder higher than the cylinder A, and communicating at its bottom with
the bottom of A by a passage b, (Fig. 2,) in the box D. The pipe F, (Fig. 2,)
through which the water leaves the boiler on its way to be tested in the
cylinder A, communicates by a cock G in the box D with a pipe H, which
extends up nearly to the top of the cylinder E, and some distance higher than
the top of the overflow pipe I of the cylinder A. The pipe H is provided
with openings c, c, (Fig. 2,) near the top, for the exit of the water. The
overflow pipe I of the vessel A communicates by a cock J in the box D with
a waste pipe K.
To provide for the support of the instrument, the passage box D is furnished
with flanges d, d, (Figs. 1 and 2,) whereby it may be bolted to the boiler, or to
a bulkhead, or other convenient place. The cylinder A is fitted with a cover L.
(Fig. 4,) which need only be removed to permit the introduction of the sali-
nometer and thermometer, and the cylinder E is fitted with a cover M, which
has openings e, e, provided in it for the escape of steam.
To test the water in the boiler the cover L is removed, and the thermometer
and salinometer are placed in the cylinder A. The cocks G and J are then
opened, and the water from the boiler flows up through the pipe H, and
through the holes c, c, into the cylinder E, and thence through the passage b
to the cylinder A, it being kept at the same level f, f, (Fig. 2,) viz., even with
the mouth of the overflow pipe I in both cylinders, and escaping by the pipes
I, K. In passing through the pipe H and cylinder E, the temperature of the
water is so far reduced, that whatever may be the pressure and the temperature
in the boiler, there is no ebullition in the cylinder A, and hence there is no
difficulty in ascertaining accurately by the salinometer the density or saltness

page_text: of the water, besides which there is neither danger of scalding the engineer,
nor of breaking the glass of the salinometer or thermometer.. The flow of
water through the apparatus can be so regulated by a proper opening of the
cocks G, J, as. to maintain the desired temperature of water in the vessel E.
! Having now described the Invention that has been communicated to me by
my foreign correspondent as aforesaid,. and explained the manner. of carrying
the same into effect, I claim as the Invention secured to me by Letters.
Patent as aforesaid, the employment, in combination with the cylinder or sali-
nometer case A, of a cylinder E, or other equivalent. vessel communicating
with the cylinder or. case A and with the boiler; as herein described, for the
purpose set forth:
In witness whereof, I, the said William Edward Newton, have hereunto
set my hand and seal, the Thirty-first day of January, in the year of
our Lord One thousand eight hundred and sixty.
Witness,
J. W. MOFFATT;
