SCAMP, of 11, Charlton Terrace, Woolwich, in the County of Kent, Surveyor,
send greeting.
WHEREAS ller present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Sixteenth day of February, in the fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said William Scamp, Her especial licence, full power, sole privilege and
authority, that I, the said
I, the said William Scamp, my exors, admors, and
assigns, or such others as I, the said William Scamp, my exors, admors, 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 Her said Majesty's Colonies
and Plantations abroad, my Invention of "AN APPLICATION OF MACHINERY TO
STEAM VESSELS FOR THE REMOVAL OF SAND. MUD, SOIL, AND OTHER MATTERS PROM
THE SEA, RIVERS, DOCKS, HARBOURS. AND OTHER BODIES OF WATERS: " in which
said Letters Patent is contained a proviso that 1, the said William Scamp,
shall cause a particular description of the nature of my said Invention, and
in what manner the same is to be performed, to be inrolled in ller said
Price 8d.1

page_text: Majesty's High Court of Chancery within six calendar months next and
immediately after the date of the said in part recited Letters Patent, as in
and by the same, reference being thereunto had, will more fully and at large
appear.
NOW KNOW YE that in compliance with the said proviso, I, the said
William Scamp, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, are fully described and
ascertained in and by the following statement thereof, reference being had to
the Drawing hereunto annexed, and to the figures and letters marked thereon
(that is to say):-
My Invention relates to a mode of applying an apparatus or machinery
in combination with the machinery for propelling a steamboat, to agitate and
stir up the sand, mud, soil, and other matters at the bottom of the water
of the sea, rivers, docks, harbours, and other bodies of water, and thus to
cause the same to mix with the surrounding water, and by the flowing off
of the water to remove such sand, mud, soil, and other matters which may
from time have settled from the place where the same has accumulated.
And in order that my Invention may be most fully understood, and readily
carried into effect, I will proceed to describe the Drawing hereunto annexed,
in the various Figures of which the same letters of reference indicate similar
parts wherever they occur, and which Drawing, with all the figures and expla-
nations written thereon, I desire may be deemed and considered as part of
this my Specification.
DESCRIPTION OF THE DRAWING
Figure represents the side view of so much of a steamboat with its
machinery as will enable me to explain the nature and use of the apparatus or
machinery combined therewith, according to my Invention. Figure 2 is a
plan of Figure 1; and Figure 3 is an end view of the agitator, separately, on
a larger scale. a, a, is an agitator, which when in action is made to revolve
on its axis by the steam engine, and is drawn along the bottom of the water
by means of the steam vessel to which the machinery for propelling the
apparatus or machinery (of which the agitator is part) is connected. b, b, are
two side rods by which the revolving agitator is applied to the steam engine
of the steamboat. At the lower ends of the side rods b, b, the axes or necks
of the revolving agitator is applied, as will be seen on examining the Drawing,
the upper ends of the side rods b, b, being supported, yet capable of free
movement on the axis c, in order that the revolving agitator, as it is drawn

along the bottom of the water, may rise and fall according to the variations of
the bottom. The axis c receives rotatory motion from the paddle shaft of the
steam engine or engines used for propelling the steamboat, as is shewn, and
in a short steamboat no second shaft c will be necessary, the main or paddle
shaft of the steam engine or engines being in such case used instead thereof.
On the axis care affixed two pulley's d, by means of which rotatory, motion is
communicated to the agilator a as it is drawn along the bottom of the water
by the steamboat.. On the axes or necks of the rotatory agitator are affixed
two pulleys e, which, by means of endless chains, receive rotatory motion
from the axis c, all which will readily be understood on an examination of
the Drawing. In working in docks or other waters, the bottoms of which
require to be cleared or cleansed from sand, mud, soil and other matters, by
the moving of the steam vessel, and the drawing of the rotatory agitator over
the bottom of the water to be cleansed, the mud, sand, and other matters
will be stirred up and mixed with the surrounding water, and in the running or
moving off of such waters in a tide or stream way, the mud, sand, and other
matters will be carried away from the dock or other locality where such
matters may have accumulated; and when the agitator is not required for use,
it is to be raised out of the water by the chains and windlass for that purpose,
as is shewn in the Drawing.
.
Now, therefore, I do not claim as my Invention any portion of the apparatus
or machinery which is attached to the machinery for propelling steam vessels,
nor the application or attachment of machinery generally to steamboats for
the purposes expressed in this my Specification; nor do I confine myself to
the precise arrangement of apparatus or machinery herein described; provided
the peculiar character of my Invention, videlicet, that of an apparatus or
machinery applied to the machinery for propelling a steam vessel for the
purpose of producing a rotatory motion in the agitator be retained. But what
I claim as the Invention secured by the above-recited Letters Patent is, the
mode of applying apparatus or machinery for the purpose of producing a
rotatory motion in the agitators, and, for the object above specified, to the
machinery for propelling steam vessels in the manner above described, to stir
up the sand, mud, soil, and other matters, and thus causing them to mix with
the surrounding waters.
In witness whereof, I, the said William Scamp, have hereunto set my
hand and seal, this Thirtieth day of April, in the year of our Lord
One thousand eight hundred and forty-one.
WILLIAM (L.s.) SCAMP.

year of our Lord 1841, the aforesaid William Scamp came before our said
Lady the Queen in Her Chancery, and acknowledged the Specification afore-
said, and all and every thing therein contained and specified, in form above
written. And also the Specification aforesaid was stamped according to the
tenor of the Statute made for that purpose.
