Year: 1852

page_text: LETTERS PATENT to Thomas Wood, of the Glue Works, Hunslet,
in the Parish of Leeds, in the County of York, Millwright, for
the Invention of "IMPROVEMENTS IN THE MODE OF OBTAINING MOTIVE
POWER."
Sealed the 17th May 1853, and dated the 26th November 1852.
PROVISIONAL SPECIFICATION left by the said Thomas Wood at
the Office of the Commissioners of Patents, with his l'etition,
on the 26th November 1852.
I, THOMAS WOOD, of the Glue Works, Hunslet, in the Parish of
Leeds, in the County of York, Millwright, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN THE MODE OF OBTAIN-
ING MOTIVE POWER" to be as follows:-
My Invention consists in obtaining motive power by means of a
wheel, the periphery or rim of which presses on water, or any other
fluid, confined within a box or case, or larger wheel, to which a
backward and forward, or rotatory, motion is cominunicated by
incchanical means.

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
THOMAS WOOD, of the Glue Works, Hunslet, in the Parish of Leeds,
in the County of York, Millwright, send greeting,
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent bearing date the Twenty-sixth day of November, in
the year of our Lord One thousand eight hundred and fifty-two, in
the sixteenth year of her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Thomas Wood, Her special
licence that I, the said Thomas Wood, my executors, administrators,
and assigns, or such-others-as I, the said Thomas Wood, my exccu-
tors, 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 THE MODE OF OBTAINING MOTIVE POWER," upon the
condition (amongst others) that I, the said Thomas Wood, by an
instrument in writing under my hand and seal, should particularly
describe and ascertain the nature of my 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 Thomas Wood, 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, reference being had-to the Draw-
ings hereunto annexed, and to the letters and. figures marked.
thercon (that is to say): --
My Invention of improvements in the mode of obtaining motive
power relates to a novel arrangement or construction of parts con-
sisting principally of a wheel which is made to roll backwards and
forwards, and press on a body of water, or any other liquid, confined
in a box or case, which is, by the pressure of the wheel on the water,
made to move or slide backwards and forwards upon a level foun-
dation plate.

page_text: In combination with this wheel and water chamber, 1 employ
weights, which are made alternately to rise and full, and by means
of levers and suitable gearing to act upon the wheel.
In order, however, that the arrangement, construction, and opc-
ration of the several parts may be clearly understood, I have shewn
in the accompanying Drawings various views of the entire mecha-
nism. Fig. 1, is a side elevation; Fig. 2, is a plan view of the
machine or apparatus, as seen from above; Fig. 3, is an end eleva-
tion, some of the parts being shewn in section; A, is the foundation
plate of the machine; B, the box or case in which water or other
liquid is confined: this box rests upon the foundation plate A; the
under surface of the wheel C, works within the box: D, D, are con-
necting rods, whereby motion is communicated from the wheel C, to
cranks E, E, and vice versa; F, F, are two loose pulleys, to which
weighted sheet iron belts, bands, or chains, G,. G, are made fast;
H, H, are two tooth pinions, fixed on or attached to the hubs of the
pulleys F, F; two ratchet wheels I, I, are keyed upon the crank
shafts, and are acted upon by the clicks or palls f, which are secured
to one of the arms of the weighted pullies F: two sector racks J, J,
are mounted loosely on the shafts, K, K, and gear into the pinions
H, H, on the crank shaft, and therefore when the sectors are moved
on their shafts, they will by means of the click f, of the pullies F, F,
move round the ratchet wheel I, I: the sliding box or case B, is, by
incans of the rods L, L, connected to the lower end of the levers K,
K, which are keyed on to the same shaft as the sectors J. A rack
M, is fixed to the foundation plate, and into this rack works a sector
N, which is keyed upon the shaft of the wheel C: this sector, by
gearing into the fixed rack M, causes the wheel C, to revolve as it
advances and presses against the confined water or fluid in the box
B: two force pumps O, O, are adapted to the sliding box or casc B,
one at each end thereof, for the purpose of forcing water or any
other fluid into the said box or case B: these force pumps can be
worked in the usual way by crank motion, which may be connected
to any convenient part of the machinery, or the box may be supplied
by the weight of a column of water in a pipe; P, P, P, P, are four

page_text: columns or supports to receive the imoving parts at each end of the
foundation plate; 'Q, Q, Q, 'Q, arc four other columns, to which are
fixed parallel bars *, *, between which the shaft of the wheel C,
moves to and fro, and is thereby kept down on the foundation plate;
four parallel bars R,'R, keep down the moveable box or case B.
When the machine is put in operation, the weight G, that is drawn up,
is set at liberty, and acts upon the pulley F, and crank rod D, and
wheel C, which is by this means pressed against the confined water
in the box or case B. The wheel C, and box or case B, then move
forward, and the other end of the box that is connected to the rod
L, and lever-K, draws up the opposite weight G., at the same time
that the crank E, and the catches of the wheel F, are travelling
round to the level centre.. This operation takes place alternately at
cach end of the machine, as the weights, by ascending and descending,
act by means of the moving parts upon the wheel C, which forms a
leverage and pressure against the confined water or fluid in the box
of case B.
Having now described my Invention, and the best means with
which I am acquainted for carrying the same into effect, I claim, in
conclusion, the combination of the wheel C, with the moveable or
sliding box or case B, in which water or any other fluid is confined,
and on which the periphery of the wheel C, is made to press.¨
In witness whereof, I, the said Thomas Wood, have hereunto set
my-hand and scal, this Twenty-fifth day of May, in the year
'of our Lord One thousand eight hundred and fifty-three.
