IMPROVEMENTS IN APPLYING WIND POWER. FOR WORKING SHIPS' PUMPS
Year: 1867

page_text: LETTERS PATENT to John Griffith, of Menai. Bridge, in the County of
Anglesey, for the Invention of "IMPROVEMENTS IN APPLYING WIND POWER.
FOR WORKING SHIPS' PUMPS."
Sealed the 13th September 1867, and dated the 13th March 1867.
PROVISIONAL SPECIFICATION left by the said John Griffith at the
Office of the Commissioners of Patents, with his Petition, on the 13th
March 1867..
I, JOHN GRIFFITH, of Menai Bridge, in the County of Anglesey, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN APPLYING
WIND POWER TO SHIPS' PUMPS," to be as follows (that is to say):-
The object of this Invention is to relieve ships and other navigable vessels
from bilge water. In applying this Invention to a ship it is preferred to use a
supplementary or extra pump, which passes through the decks a short distance
in advance of the mizen mast, and erecting a pair of stout vertical poles
placed a little distance apart springing from each side of the pump and con-
nected together by horizontal bars. The top of these poles is fitted with a
horizontal metal collar having flanches or lugs extending down the poles,
through which the same is bolted or otherwise attached thereto; this circular
collar is fitted with a pair of travelling bearings, which carry a horizontal
crank shaft, on one end of which is fitted a metal boss having two, three, or more
short socket arms, each of which is fitted with a wooden pole, which forms
the foundation or principal rib carrying framework or ladder on which the

page_text: canvas forming the sails of the windmill are fitted. The travelling bearing
on the reverse end to that on which the mill sails are placed is formed with a
socket on each side, in which is inserted a horizontal split lever of wood or
other suitable material, to the outer end of which is attached a guy rope or
ropes for turning round the sails to face the wind when the same are in
action. The revolving bearings, in which the crank shaft works, are fitted
on the under sides with plates of metal, so as to form a groove encompassing
the outer edge of the circular flange, thus securing the bearings thereto. The
spear of the pump is attached by a connecting rod of the required length
to the crank on the crank shaft, the upper part of the rod of the spear box
working through a fixed guide which extends from pillar to pillar a little
above the pump head. The lower end of the connecting rod and head of the
spear box rod are connected together by a joint, which allows of the
connecting rod to be turned round and fallow the crank,
When it is desired to bring the apparatus into operation the arms of the
mill are turned to face the wind, where they are secured by the guy ropes
on the end of the horizontal lever when the sails are spread on the framework
of the arms of the mill, when the action of the wind causes the same to rotate,
and thus sets the pump in motion.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Griffith in the Great Seal Patent Office on the 18th
September 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
GRIFFITH, of Menai Bridge, in the County of Anglesey, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of March, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said John Griffith, Her special licence that 1, the said John Griffith, my
executors, administrators, and assigns, or such others as I, the said John
Griffith, 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 APPLYING WIND POWER
FOR WORKING SHIPS' PUMPS," upon the condition (amongst others) that I,

page_text: the said Jon mtu, my Caccutors
writing under my, or their, or one of their hands and seals, should particu-
Jarly 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 John Griffith, 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 statenient
(that is to say):-
}
The object of this my said Invention is to relieve ships and other navigable
vessels from bilge water. In applying this 'my said Invention to a ship I
prefer to use a supplementary or extra pump, which passes through the decks
a short distance in advance of the mizen mast, and to erect a pair of stout:
vertical poles placed a little distance apart springing from each side of the
pump, and connected together by horizontal bars. The top of these poles I
fit with a horizontal metal collar having flanches or lugs extending down the
poles through which the same is bolted or otherwise attached thereto; this
circular collar I fit with a pair of travelling bearings which carry a horizontal
crank shaft, on one end of which is fitted a metal boss having two, three, or
more short socket arms, each of which is fitted with a wooden pole which forms
the foundation or principal rib carrying the framework or ladder on which
the canvas forming the sails of the windmill are fitted. The travelling
bearing on the reverse end to that on which the mill sails are placed is formed
with a socket on each side, in which is inserted a horizontal split lever of
wood or other suitable material, to the outer end of which is attached a guy
rope or ropes for turning round the sails to face the wind when the same are
in action. The revolving bearings in which the crank shaft works are fitted
on the under sides with plates of metal so as to form a groove encompassing
the outer edge of the circular flange, thus securing the bearings thereto. The
spear of the pump is attached by a connecting rod of the required length to
the crank on the crank shaft, the upper part of the rod of the spear box
working through a fixed guide which extends from pillar to pillar a little
above the pump head; the lower end of the connecting rod to be turned
round and follow the crank. When it is desired to bring the apparatus into
operation the arms of the mill are turned to face the wind, where they are
secured by the guy ropes on the end of the horizontal lever; when the sails
are spread on the framework of the arms of the mill, when the action of the
wind causes the sanie to rotate, and thus sets the pump in motion.

page_text: That this my said Invention may be the more readily understood I have
hereunto annexed Drawings of so much of the apparatus as will be necessary
to illustrate the same; like letters and figures marked thereon being used to
denote similar parts.
Figure 1 is an elevation of the apparatus, and Figure 2 is a partial sec-
tional elevation of the same, and Figure 3 is a partial top view or plan of
the same. A, vertical standards which are fitted on the top with B a cireular
flanged collar, on which works C a ring which carries D the bearings of E,
horizontal crank shaft, on the outer end of which is keyed F a wooden pulley
to be used as a break, and G, socketed arms, which receive H the mill sails; J, a
circular collar screwed on to the under side of C to keep the same in place, and
at the same time allow it to be turned round horizontally; K, pump barrel;
L, pump bucket; M, spear of the pump; N, connecting rod; P, lever for
turning the mill sails round; Q (Figure 1), break lever which acts on the
break wheel F.
Having now fully described and ascertained the nature of this my said
Invention, and how, I believe, the same may be best carried into practical
effect, I wish it to be understood that I do not confine myself to the several
proportions or dimensions shown, as it will be readily seen the same may be
considerably varied without departing from the Invention; but what I claim
is, the general construction and combination of the several parts of the
apparatus substantially in the manner and for the purposes herein-before
described and set forth.
In witness whereof, I, the said John Griffith, have hereunto set my band
and affixed my seal, this Eleventh day of September, in the year of
our Lord One thousand eight hundred and sixty-seven.
Witness,
WILLIAM WALKER,
of 44, Castle Street,
Liverpool.
