Year: 1833

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
HOWARD KYAN, of Upper Baker Street, in the County of Middlesex, Esquire,
send greeting.
WHEREAS His present most Excellent Majesty King William the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date
at Westminster, the Twenty-first day of December, in the fourth year of His
reign, did, for Himself, His heirs and successors, give and grant unto me,
the said John Howard Kyan, His especial licence, that I, the said John
Howard Kyan, my exors, adñññors, and assigns, or such others as I, the said
John Howard Kyan, my exors, adiñors, or assigns, should at any time agree
with, and no others, from time to time and at all times during the term
of years therein expressed, should and lawfully might make, use, exercise,
and vend, within England, Wales, and the Town of Berwick-upon-Tweed,
and also in all His said Majesty's Colonies and Plantations abroad, my
Invention of "A NEW COMBINATION OF MACHINERY TO BE APPLIED TO THE
PRESENT PURPOSES OF STEAM NAVIGATION IN AID OF OR IN SUBSTITUTION FOR THE
MOTIVE POWER HITHERTO AND AT PRESENT OBTAINED AND AFFORDED BY THE APPLI-
CATION OF STEAM;" in which said Letters Patent is contained a proviso obliging
me, the said John Howard Kyan, by an instrument in writing under my hand
and seal, particularly to describe and ascertain the nature of my said Invention,
and in what manner the same is to be performed, and to cause the same
to be inrolled in His Majesty's High Court of Chancery within six calendar
months next and immediately after the date of the said recited Letters
Patent, as in and by the same, reference being thereunto had, will more fully
and at large appear.

page_text: Figure 2 is a section of a vessel showing a side elevation of the machinery
shown in Figure 1. Where the vessel is of large dimensions, two or more
reciprocating water barrels or pumps, with their necessary ejects, may be
applied on each side on the plan before-mentioned, to give the requisite
velocity. Where it is required to adopt this mode of propulsion to steam
boats of the ordinary construction, it is only necessary to convey the power
from the vertical steam engine or revolving cranks to the small rods and
pistons c, d, of the water cylinders C, D, by means of connecting rods, beams,
or levers in the manner ordinarily adopted for such purposes.
Now, whereas I claim as my Invention the combination of machinery
herein-before described for the purposes aforesaid, whereby I am enabled to
substitute the motive power of the expelled water for that of the paddle wheels
now used, and such my Invention being to the best of my knowledge and
belief entirely new, and never before used within that part of His said Majesty's
United Kingdom of Great Britain and Ireland called England, His said
Dominion of Wales and Town of Berwick-upon-Tweed, or in any of His said
Majesty's Colonies and Plantations abroad, I do hereby declare this to my
Specification of the same, and that I do verily believe this my said Specifi-
cation doth comply in every respect fully and without reserve or disguise with
the proviso in the said herein-before in part recited Letters Patent contained;
wherefore I do hereby claim to maintain exclusive right and privilege to my
said Invention.
In witness whereof, I, the said John Howard Kyan, have hereunto
set my hand and seal, this Twenty-first day of June, One thousand
eight hundred and thirty-four.
