Year: 1863

page_text: LETTERS PATENT to William Clark, of 53, Chancery Lane, in the County
of Middlesex, Engineer and Patent Agent, for the Invention of "IM-
PROVEMENTS IN MOUNTING AND FITTING BEDSTEADS, CHAIRS, AND OTHER
MOVABLE SEATS ON BOARD SHIP."-A communication from abroad by
Herman Hobach and Martin Henri Rumpf, both of 29, Boulevart St.
Martin, Paris, Commission Agents.
PROVISIONAL SPECIFICATION left by the said William Clark at the
Office of the Commissioners of Patents, with his Petition, on the 8th
June 1863.
I, WILLIAM CLARK, of 53, Chancery Lane, in the County of Middlesex,
Engineer and Patent Agent, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN MOUNTING AND FITTING BEDSTEADS, CHAIRS, AND
OTHER MOVABLE SEATS ON BOARD SHIP," to be as follows:-
This Invention relates to improvements in mounting and fitting bedsteads,
chairs, and other movable seats used on board ship for the purpose of pre-
venting sea sickness.
For this purpose I suspend these bedsteads and chairs similarly to the
method of mounting ships' compasses and other objects in frames furnished
with axes at right angles to each other, in such manner that notwithstanding
the rolling or pitching of the vessel the bedstead or chair shall always retain a

page_text: vertical position, and be independent of the motion of the ship. For chairs I
place one of the axes in an inclined direction, while for bedsteads I place both
in a horizontal position.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Clark in the Great Seal Patent Office on the
5th December 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
CLARK, of 53, Chancery Lane, in the County of Middlesex, Engineer and
Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of June, 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 William Clark, Her special licence that I, the said William Clark,
my executors, administrators, and assigns, or such others as I, the said
William Clark, 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 for "IMPROVEMENTS IN
MOUNTING AND FITTING BEDSTEADS, CHAIRS, AND OTHER MOVABLE SEATS ON BOARD
SHIP,"
a communication to me from abroad by Herman Hobach and Martin
Henri Rumpf, both of 29, Boulevart St. Martin, Paris, Commission Agents,
upon the condition (amongst others) that I, the said William Clark,
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 William Clark, 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, reference being had to the Sheet of. Drawings hereunto annexed,
and to the letters and figures marked thereon (that is to say) :-
This Invention relates to improvements in mounting and fitting bedsteads,

page_text: chairs, and other movable seats used on ship board for the purpose of pre-
venting sea sickness.
For this purpose I suspend the bedsteads and chairs similarly to the
method of mounting ships' compasses and other objects in frames furnished
with axes at right angles to each other, in such manner that notwithstanding
the rolling or pitching of the vessel the bedsteads or chairs shall always retain
a vertical position and be independent of the motion of the ship. For chairs
I place one of the axes in an inclined direction, while for bedsteads I place
both in a horizontal position.
This Invention is illustrated in the accompanying Drawing, two examples
only being shown as applied to a bedstead and chair.
Figs. 1 and 2 represent the bedstead as preserving its vertical position with
the deck or floor at various degrees of inclination; Fig. 3 represents a chair.
The letters apply to all the Figures.
a, standards of any suitable form secured to the deck of the ship; b, sus-
pending frame oscillating on standards a, being furnished with two pivots c;
d, bedstead or chair forming the second suspensory arrangement, oscillating on
pivots e in frame b, the pivots c and e being at right angles to each other.
Having described the nature of this Invention, and the manner of per-
forming the same, I declare that what I claim as the Invention to be
protected by the herein-before in part recited Letters Patent is, the improve-
ments in mounting and fitting bedsteads, chairs, and other movable seats to
be used on board ship, as described and represented in the accompanying
Drawing.
In witness whereof, I, the said William Clark, have hereunto set my
hand and seal, this Fourth day of December, in the year of our
Lord One thousand eight hundred and sixty-three.
Witness,
W. G. E. SWINNOCK,
53, Chancery Lane,
London.
W. CLARK. (L.S.)
