Year: 1867

page_text: LETTERS PATENT to Charles Powell Jones, of Peckham, in the County of
Surrey, Master Mariner, for the Invention of "A NEW OR IMPROVED
APPARATUS FOR REMOVING ADHERING MATTERS FROM THE BOTTOMS AND SIDES
PROVISIONAL SPECIFICATION left by the said Charles Powell Jones
at the Office of the Commissioners of Patents, with his Petition, on
the 30th September 1867.
I, CHARLES POWELL JONES, of Peckham, in the County of Surrey, Master
Mariner, do hereby declare the nature of the said Invention for "A NEW
OR INPROVED APPARATUS FOR REMOVING ADHERING MATTERS FROM THE BOTTOMS
AND SIDES OF SHIPS OR OTHER NAVIGABLE VESSELS WHILST AT SEA," to be as
follows (that is to say):-
My Invention has reference to a more effectual and expeditious method of
cleaning the bottoms and sides of vessels aforesaid from all adhering matters,
such as barnacles, grass, weed, or other submarine accumulations, by employing

page_text: for the same a double scraper rendered buoyant by corks or otherwise, so as
to closely encircle the ship and admit of being heaved or dragged fore and aft
whilst afloat through the medium of guy ropes and lines attached to the
apparatus, and consists in forming the said scraper or apparatus of flat iron
bars jointed longitudinally together by transverse rods in like manner to a
ladder, and attaching the same to a keel plate of angle iron corresponding in
size to the keel of the vessel as also in width to the scraper, the said corks
or otherwise being fixed between the transverse bars and the sides of the said
scraper, to give it the requisite buoyancy for enabling the scraper to impinge
against the bottom and sides of the vessel whilst being worked from stem to
stern as above-described.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed.
by the said Charles Powell Jones in the Great Seal Patent Office on the
10th February 1868.
TO ALL TO. WHOM THESE PRESENTS SHALL COME, I, CHARLES
POWELL JONES, of Peckham, in the County of Surrey, Master Mariner, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of September, in the year of our Lord One
thousand eight hundred and sixty-seven, in the thirty-first year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Charles Powell Jones, Her special licence that I, the said Charles Powell Jones,
my executors, administrators, and assigns, or such others as I, the said Charles
Powell Jones, 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 "A NEW AND IMPROVED
APPARATUS FOR REMOVING ADHERING MATTERS FROM THE BOTTOMS AND SIDES OF
SHIPS OB OTHER NAVIGABLE VESSELS WHILST AT SEA," upon the condition
(amongst others) that I, the said Charles Powell Jones, 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

page_text: 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 Charles Powell Jones, do hereby declare
the nature of my said Invention, and in what manner the same is to be:
performed, to be particularly described and ascertained in and by the following
statement, and the Drawings therein referred to (that is to say) :-
My Invention has reference to a more effectual and expeditious method of
cleaning the bottoms and sides of ships aforesaid from foul or adhering matters,
such as barnacles, grass, weeds, or other like submarine accumulations, by
employing for the same a jointed scraper rendered buoyant by corks or
otherwise so as to closely surround or encircle the body of the ship and admit
of being heaved or dragged fore and aft whilst afloat by means of guy ropes.
and lines attached to the apparatus, and consists in forming the said scraper
or apparatus of a series of bars or plates of iron jointed longitudinally together
to a keel piece through the medium of transverse rods and rivets, the said
corks or otherwise being fixed between or upon the transverse bars and the
sides of the said apparatus to give it the requisite buoyancy and enable the.
scraper to impinge against the bottom and sides of the vessel whilst being
worked from stem to stern or in the opposite direction as above described.
And in order that my said Invention may be more fully understood and
readily carried into effect I now proceed to describe it by the aid of the
accompanying Drawings, reference being had to the letters and figures thereon
marked (that is to say): :-
:
Fig. 1 represents a side view of a ship's scraper manufactured upon my
improved principle of construction; Fig. 2, a top or plan view thereof; Fig. 3,
a back or underneath view of the same; Fig. 4, a transverse vertical section
taken through the dotted line a, b, and Figures 5, 6, and 7, stern, side, and
keel views of a ship or vessel with my improvements applied thereto arranged
in the order in which the same are worked and put in operation for cleaning the
bottom and sides of the aforesaid ship or vessel, and Fig. 8 a perspective view
of scraper separately shown. In each Figure the same letters of reference
denote similar corresponding parts.
A, A, plates or bars of iron riveted and jointed together so as to form the
sides and scraping edges of the apparatus, and admit of the same bending and
fitting freely, and closely to the shape of the vessel when in use; B, B, trans-
verse rods or bolts for connecting and securing the said- sides of the
scraper

page_text: together; C, C, rivets forming the joints; D, D, corks or other like buoyant
material attached thereto for the purpose of communicating the requisite
floating properties to the same and enable the scraper to act in an upward
direction against the bottom and sides of the ship whilst submerged; E, E,
rectangular iron case or plate fitting to the keel of the vessel for connecting
the sides of the apparatus and guiding or controlling the lateral and
longitudinal motion of the scraper when in action; F, F, guy ropes secured
to the sides of the apparatus through the medium of loop rings or eyes G, G,
by the arrangement of which the said scraper is worked fore and aft of the
ship; H, H, lines or 'ropes attached to the lower portion of the said apparatus
"in like manner to the above," for heaving the same throughout the entire
length of the bottom of the vessel in connection with the guy ropes worked
with other suitable tackle from the deck; I, I, ship or vessel; J, J, keel of
the same.
In conclusion to the foregoing description I would here briefly note that the
said apparatus may be formed wholly or partly of wood, iron, or other
material, or combinations thereof, and varied in shape or size, and number of
the links or jointed plates, or receive such other modifications as in practice
may be found necessary and employed in either or all of the said operations of
cleaning the sides and bottoms of iron or wooden built ships or vessels.
And I would further note that the said apparatus as above described may
be used in combination with mats, brushes, or scrubbers fixed thereto, composed
of hair, cocoa, or hemp, metallic, or other fibre.
Having now fully described and ascertained the nature of this my said
Invention, and the manner in which the same is to be performed and carried
into effect, I would have it clearly understood that I do not intend to confine
myself to the precise details herein-before set forth and described, as the same
may be otherwise varied by employing in addition to the above anti-corrosive
or other preservative coatings or like preparations for protecting the surfaces
of the said scraper from oxidation or other chemical action, as may be found
suitable without departing from the general principle of this my said Invention,
nor do I claim as new and of my said Invention the exclusive use of the
several parts, combinations, and processes herein-before referred to, except
when the same are employed in and for the purposes of my said improvements,
which I hereby declare to consist in the mechanical construction and employ-
ment of jointed scrapers (fitted with a keel piece, corks, or other buoyant
materials) for cleansing the bottoms and sides of vessels by externally

page_text: surrounding and impinging against the same whilst afloat, in the manner and
for the purposes herein-before set forth and described.
In witness whereof, I, the said Charles Powell Jones, have hereunto
set my band and seal, this Sixth day of February, in the year of our
Lord One thousand eight hundred and sixty-eight.
