page_text: LETTERS PATENT to Nicholas Doran Maillard, of York Street, Dublin,
Ireland, for the Invention of "IMPROVEMENTS IN THE MEANS FOR STEERING
AND INDICATING THE COURSE OR DIRECTION AND TIME OF SHIPS AND OTHER
NAVIGABLE VESSELS AT SEA, WHICH IMPROVEMENTS ARE ALSO APPLICABLE TO
OTHER PURPOSES."
Sealed the 13th July 1860, and dated the 18th January 1860.
PROVISIONAL SPECIFICATION left by the said Nicholas Doran Maillard
at the Office of the Commissioners of Patents, with his Petition, on the
18th January 1860.
I, NICHOLAS DORAN MAILLARD, of York Street, Dublin, Ireland, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
MEANS FOR STEERING AND INDICATING THE COURSE OR DIRECTION AND TIME OF SHIPS
AND OTHER NAVIGABLE VESSELS AT SEA, WHICH IMPROVEMENTS ARE ALSO APPLICABLE;
TO OTHER PURPOSES," to be as follows:-
They consist firstly of a barrel spring and train of wheels suitably arranged
to give the required motion to a vertical or horizontal spindle. A hand or
indicator is fixed at the end of the spindle to indicate the bearing of the sun
by means of a fixed card or dial on which the divisions or points and also the
hours, minutes and seconds, are marked to show in time the variations of the
sun's bearings throughout the day and night, and there is also a dead hand or;
pointer on the dial, to mark the latitude of the ship or place. They consist,.
secondly, of wheels or other suitable mechanical arrangement connected to or:
with the head or vertical shaft of the ship's rudder, to communicate motion:
therefrom to a vertical or horizontal spindle, passing through a fixed compass:

page_text: card or dial, in a binnacle or other convenient case, and such spindle has on
the end thereof one or more hands to indicate on the card or dial, by means of
the motion communicated to the spindle from the rudder's head or shaft, the
course or direction of the ship's head, or in either of the above mentioned
improvements, the compass card may be attached to a hollow spindle passing
over the other spindle and caused to move by means of power communicated
thereto by suitable arrangements for the purpose. The improvements, secondly
above mentioned, may also be applied to instruments for surveying and other
purposes, by having a wheel at the other end of the spindle, so that as the
wheel is caused to revolve by running the same along the ground, the course
or direction of such instrument so impelled is indicated on the card or dial by
the hand, which had been previously set to the true north.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Nicholas Doran Maillard, in the Great Seal Patent Office on
the 18th July 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, NICHOLAS
DORON MAILLARD, of York Street, Dublin, Ireland, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of January, in the year of our
Lord One thousand eight hundred and sixty, in the twenty-third year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Nicholas Doran Maillard, Her special licence that I, the said
Nicholas Doran Maillard, my executors, administrators, and assigns, or such
others as I, the said Nicholas Doran Maillard, my executors, administrators,
and assigns, should at any time agree with, and no others, from time to time
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 THE MEANS FOR STEERING AND INDICATING THE COURSE OR
DIRECTION AND TIME OF SHIPS AND OTHER NAVIGABLE VESSELS AT SEA WHICH
IMPROVEMENTS ARE ALSO APPLICABLE TO OTHER PURPOSES" upon the condition
(amongst others) that I, the said Nicholas Doran Maillard, 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.

page_text: NOW KNOW YE, that I, the said Nicholas Doran Maillard, 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 by reference to the Sheet of Drawings, and
to the figures and letters marked thereon, and which form part of this
Specification.
.
My said improvements consist, firstly, of a barrel spring and train of
wheels suitably arranged to give the required motion to a vertical or horizontal
spindle; a hand or indicator is fixed at the end of the spindle to indicate
the bearing of the sun, by means of a fixed card or dial, on which the divisions,
or points of the mariner's compass and also the hours, minutes, and seconds are
marked, to shew in time the variations of the sun's bearings throughout the
day and night, and there is also a dead hand or pointer on the dial to mark.
the latitude of the ship or place. They consist, secondly, of wheels or other
suitable mechanical arrangements connected to or with the head or vertical
shaft of the ship's rudder, to communicate motion therefrom to a vertical or
horizontal spindle passing through a fixed compass card or dial, in a binnacle
or other convenient case, and such spindle has on the end thereof one or
more hands to indicate on the card or dial, by means of the motion commu-
nicated to the spindle from the rudder's head or shaft, the course or direction
of the ship's head; or in either of the above-mentioned improvements the
compass card may be attached to a hollow spindle passing over the other spin-
dle, and such hollow spindle and card may be put in motion by means of
power communicated thereto from the ship's rudder by suitable arrangements,
and so indicate the course or direction of the ship without a hand or indicator.
The improvements, secondly above mentioned, may also be applied to instru-
ments for surveying and other purposes, by having a wheel at the other end of
the spindle, so that as the wheel is caused to revolve by running the same along
the ground the course or direction of such instrument so impelled is indicated
on the card or dial thereon by the hand. which has been previously set to the
true north.
DESCRIPTION OF THE DRAWINGS.

page_text: bevil wheel B, gearing with a similar wheel C, on the end of the horizontal
shaft D, which, as will be seen on reference to Figure 1, works in a space,
formed in the deck, so as to be about flush therewith; E is a bevil wheel on:
the end of this shaft gearing with the wheel F, keyed to the vertical shaft or
spindle G, the wheel E also gears with the wheel H, which fits loosely, on
the shaft or spindle G, to the upper end of which the index hand I is fixed;
K is a hollow spindle fitting over the spindle G, having the card L fixed on
its upper end, and formed with a clutch at its lower end by means of which
the wheel is brought in gear, with the hollow spindle K, through a pro-
jection M on the boss of, the wheel H. By this arrangement the rudder
will have its required play; N is the fixed dial shewing a combination of
a compass card with a time dial below; this dial is contained the barrel
spring and train of wheels for moving the hand or indicator O, so as to
shew.time in the ordinary way; P is a dead hand or pointer to mark the
latitude of the ship or place..
I have not thought it necessary to give any Drawing of the mode of appli-
cation of my Invention to instruments for surveying and other purposes, as the
same will be readily understood from the above description. By the abovo
arrangements, I am enabled to ascertain the bearings of the sun and other.
heavenly bodies at all times, without making celestial observations, as one
indicator on the dial shews the time and bearing of the sun at Greenwich, and
the other the time and bearing of the sun at ship or other place.
Having described the nature of my said Invention, and in what manner the,
same is or may be performed, I wish it to be understood that I do not claim.
any of the parts thereof taken separately, but that what I claim as my Invention
is the combination and arrangements for steering and indicating the course or
direction and time of ships and other navigable vessels at sea and for survey-
ing and other purposes as herein-before described.

In witness whereof, I, the said Nicholas Doran Maillard, have hereunto
set my hand, and seal, the Eigteenth day of July, One thousand s
eight hundred and sixty.
