Year: 1814

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HOWARD. of Old Brentford, in the Parish of Ealing, in the County of
Middlesex, Gentleman, send greeting.
WHEREAS His present Majesty King George the Third, by His Letters
Patent under the Great Seal of Great Britain, bearing date at Westminster,..
the Tenth day of November now last past, did give and grant unto me, the
said William Howard, His especial licence, full power, sole privilege and
authority, that I, the said William Howard, my executors, administrators,
and assigns, and such others as I, the said William Howard, my executors,
administrators, or assigns, should at any time agree with, and no others,
from time to time and at all times thereafter 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, my Invention of
"AN IMPROVED APPARATUS OR GEAR FOR WORKING THE PUMPS ON BOARD SHIPS,
WHICH MAY ALSO BE APPLIED TO CHURNING AND VARIOUS OTHER USEFUL PURPOSES ON
SHORE;" in which said Letters Patent there is contained a proviso obliging
me, the said William Howard, 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 said 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 said recited Letters Patent, reference being thereunto
had, will more fully appear..

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
William Howard, do hereby describe and ascertain the nature of my said
Invention, and the manner in which the same is to be performed, as follows
(that is to say):-
-
My said Invention is represented in the perspective Drawing Figure I.
licreto annexed, and consists of the application of cranks upon a spindle
supported by stancheons as there seen, to which cranks the pump (or piston)
rods are attached and put in motion by the revolution of the said spindle, by
means of bevel cog wheels acting at right angles, and a handle and fly wheel
to give motion as there represented, but more fully described by the following
Figures.
Figure II. in the said Drawing hereto annexed exhibits a horizontal view
of the apparatus supported by the stancheons (a, b, b, c, and d); and
Figure III. in the said annexed Drawing exhibits a side view of that part
of the apparatus which is supported by the middle stancheons (b, b, and d),
the same letters referring to the same respective parts in every Figure. A, A,
are cranks to which the pump (or piston) rods are to be attached, and which
cranks are affixed to the square ends of spindle by bolt, screw, or other means,
or may be made in one piece with the spindle. B, B, the spindle supported
upon the stancheons (a, b, and c) as seen in Figure I. C, the bevel cog
wheel fitted to a square in the spindle against the shoulder D, and fastened
with a pin or bolt. E, the lesser bevel cog wheel working into the greater
cog wheel C at right angles, fixed upon the fly wheel arbour F, F, which
arbour is supported by the stancheons (b, b, and d), as seen in Figure III. G, the
fly wheel, and H, the handle to give motion to the apparatus. When a greater
power is required, take off the cog wheel E from the fly wheel arbour, and
substitute one of smaller diameter, as E 1, when it will be necessary to place a
collar I upon the spindle, between the cog wheel C and the shoulder D, in
order to bring the bevel wheel C to act into the teeth of the lesser wheel.
Figure IV. in the said annexed Drawing represents a horizontal view of a
different application of wheels for working the spindle and cranks.
In this
Figure the cog wheels work into each other in a right line. A, A, the cranks;
C, the cog wheel fitted on the square of the spindle B, which is supported by
the stancheons (e and f); E, the lesser cog wheel fitted on the square of the
fiy wheel arbour F, and supported by the stancheons (f and 9). The side view
of the middle stancheon (f, f.) is represented in Figure V. in the said annexed
Drawing, and shews the manner in which the cog wheels work into each other:
the fly wheel in this case may be affixed on either side of the stancheon (g),
and the handle fitted on a square at the end of the arbour, or the handle may

and supported by another stanchcon at its extremity; in which case the fly
wheel can be made to work in the ship's side, with a square on the inside for
to receive the crank, and a square on the outside, to which a water wheel can
be applied to render the apparatus self-acting. To accelerate the action of the
pumps worked upon the latter principle a cog wheel of larger diameter may
be substituted instead of the cog wheel E, Figures IV. and V.; in which case
the brass dies K fitted in the stancheons (f and g) may be turned round in
their places, the holes for the arbour to turn in being at that distance from the
center of the dies as the semi-diameter of the cog wheel E 2 is larger than the
one for which it is substituted. All the Figures, except the perspective view,
Figure I., are drawn upon a scale of three inches to the foot, but I do not
intend confining myself precisely to these dimensions.
In witness whereof, I, the said William Howard, havo hereunto set my
hand and seal, the Ninth day of May, in the fifty-fifth year of the
reign of our Sovereign Lord George the Third, by the Grace of God of
the United Kingdom of Great Britain and Ireland King, Defender
of the Faith, and in the year of our Lord One thousand eight hundred
and fifteen
