page_text: LETTERS PATENT to. Thomas Massey, of 4, Birchin Lane, in the City of
London, and Thomas Savage, of 19, Soley Terrace, Pentonville, in. the
County of Middlesex, for the Invention of "IMPROVEMENTS IN SOUNDING.
MACHINES."
Sealed the 12th January 1858, and dated the 17th October 1857.
PROVISIONAL SPECIFICATION left by the said Thomas Massey and
Thomas Savage at the Office of the Commissioners of Patents, with
their Petition, on the 17th October 1857.
We, THOMAS MASSEY, of 4, Birchin Lane, in the City of London, and
THOMAS SAVAGE, of 19, Soley Terrace, Pentonville, in the County of Middlesex,
do hereby declare the nature of the Invention for "IMPROVEMENTS IN SOUNDING
MACHINES," to be as follows:-
This Invention has for its object improvements in those descriptions of
sounding machines known as Massey's sounding machines, and having screws
or flys, which, as the apparatus descends through the water, rotate and give
motion to a train of wheels, by which the number of revolutions of the fly, and
consequently the depth it sinks through, are recorded. In order to cause this
apparatus to sink in an upright position and with sufficient velocity through
the water, it has to be attached to a long and heavy lead, and so, when the
machine is hauled in, after taking a sounding, it sometimes comes in violent
contact with the side of the ship, by which the machine is injured. Now, our

page_text: Invention consists in fixing to the bar which carries the lead or weight guards
so arranged as to protect the machine from injury in this way.
These guards
consist of rings or bands of metal surrounding the machine, or in place
thereof, it may be enclosed in a cylindrical cage of wirework or sheet metal,
left open at the top and bottom to permit of the free passage of the water.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Massey and Thomas Savage, in the Great Seal Patent
Office on the 15th April 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wе, THOMAS
MASSEY, of 4, Birchin Lane, in the City of London, and THOMAS SAVAGE, of
19, Soley Terrace, Pentonville, in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of October, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Thomas Massey and Thomas Savage, Her special licence that we, the
said Thomas Massey and Thomas Savage, our executors, administrators, and
assigns, or such others as we, the said Thomas Massey and Thomas Savage,
our 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 for "IMPROVEMENTS IN SOUNDING
MACHINES," upon the condition (amongst others) that we, the said Thomas
Massey and Thomas Savage, our executors or administrators, by an instru-
ment in writing under our or their hands and seals or under the hand and
seal of one of us or them, 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 we, the said Thomas Massey and Thomas Savage
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 thereof, that is to say:-
This Invention has for its object improvements in those descriptions of
sounding machines known as Massey's patent sounding machines, and having

page_text: thick is suitable for the purpose. The guard, together with the bar b, to
which it is fixed, may be galvanized to protect it from rust.
The sounding
line is attached to the machine in, such a manner that it may be readily
detached from it. after it has been used. For this purpose the line is made
fast to a forked piéce g, which is furnished with an eye g', for the purpose, and
this forked piece is fixed to the machine when required for use, by a screw
bolt h passing through it and through the bar b, as is shown in the Drawing.
The bolt h is furnished with a short arm h¹ at one end, and this arm has a
projection on it, which by coming in contact with the piece g, prevents the
bolt from turning round, while its nut is screwed up.
In witness whereof, we, the said Thomas Massey and Thomas Savage,
have hereunto set our hands and seals, this Thirteenth day of April,
in the year of our Lord One thousand.eight hundred and fifty-eight.
Witness,
S. CARPMAEL.
