page_text: TO ALL TO WHOM THESE PRESENTS MAY OR SHALL COME,
I, JAMES TREMEERE, late of Lambsconduit Passage, in the Parish of Saint
George the Martyr, and County of Middlesex, but now of Hinde Street,
Manchester Square, in the same County, Carpenter, send greeting.
WHEREAS His present Majesty King George the Third, by His Letters
Patent, bearing date at Westminster, the Third day of October, in the forty-first
year of His reign, hath given and granted unto me, the said James Tremeere,
my executors, administrators, and assigns, special licence, full power, sole
privilege and authority, during the term of years therein expressed, to make,
use, exercise, and vend, within England, Wales, and the Town of Berwick-
upon-Tweed, my Invention of "A METHOD OF WORKING BARGES AND
VESSELS, AS WELL LOADED AS UNLOADED, ALONG CANALS OR OTHER STILL WATERS, OR
ALONG WATER HAVING A MODERATE CURRENT, WITHOUT HORSES OR MEN TO DRAW
THEM;" in which said Letters Patent there is contained a proviso obliging me,
the said James Tremeere, particularly to describe and ascertain the nature of
my said Invention, and in what manner the same is to be performed, under
my hand and seal, and cause the same to be inrolled in His Majesty's High
Court of Chancery within six calendar months next after the date of the said
Patent, as in and by the same, reference being thereunto had, may more fully
and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
James Tremeere, do hereby declare that the nature of my said Invention, and
the manner and several ways by which the same is to be performed, is

page_text: described and ascertained in the plans hereunto annexed, and the following
description.
Drawing No. 1. is the form of the machine when intended to be worked by
a winch or handle, and a grooved wheel or barrell annexed to the main axle.
In that Drawing, A denotes the frame work of the machine. B, the main
axle, to which the floats E are fixed, which axle may be made either of wood
or iron. C, an iron gudgeon, one of which is to be fixed in the centre of each
end of the axle B. D, an iron or brass step or socket, one to be placed at
each end of the axle, and in which the gudgeon C works. E, the floats
(made of wood), which may be from four to eight in number, on each side the
centre of the axle, and may be made to fold occasionally, when in harbour,
by means of hinges or joints, and reinstated at pleasure, and kept in place
by means of a bolt or bolts after mentioned; F, the joints or hinges and
bolt or bolts mentioned in E. G, the spokes to which the floats are fixed
by means of iron bolts and nuts, and which spokes must be let into the
axle if wood, if iron, to be fixed thereto by means of a wooden nave. H,
the braces which connect and strengthen the spokes, and are to be fastened
thereto with bolts and nuts in the same manner as the floats are to be fastened
to the spokes. I, a wooden frame fixed into the frame A, in which the wheels
mentioned in L, N, O, and P, work. K, a grooved wheel or barrell of wood
or iron which is fixed on the axle B. L, a grooved wheel or barrell to corre-
spond with the wheel or barrell K, and to which it is connected and gives
motion by means of the line or chain M; it acts on a spindle, which works
in brass or iron steps or sockets let into the frame I, and made similar to
those marked D. M, the line or chain which works round the wheels K and
L, and gives motion to the floats E. N, a side cog wheel, of either brass or
iron, which is attached to the wheel L, acts on the same spindle, and is turned
by the bevil geer wheel or pinion O. O, is the bevil geer wheel or pinion of
brass or iron above mentioned, and is worked with a winch and fly wheel in
brass or iron steps or sockets. P, the spindle with winch and fly wheel men-
tioned in O, which winch puts the whole machine in motion by being con-
tinually turned by a man. Q, the brass or iron steps or sockets last mentioned.
R, the hinges or joints which connect frame A to the barge or vessel Y, and are
to be made with eyes or sockets to slide on a round or square bar of iron
which is fixed at the end of the barge or vessel, and made with a joint to
turn up occasionally. S, a rack and pinion to raise and lower the frame A
according to the lading of the barge or vessel and draught of water. T, a
wooden upright, one of which is to be placed on each side of the barge or
vessell next the machine with pullies, through which the lines or chains U
'

page_text: pass, to raise or lower the front of the frame A. U, the lines or chains acting
through the pullies on the uprights T for the purpose above described. W, a
windlass with rotchet wheels, round which the line or chain U is wound, in the
action of raising the front of the frame A, and may be worked either by a
handspike or by a winch. X, the rotchet wheels and catch. Y, the barge or
vessel. Z, the pullies through which the line U passes.
Drawing No. 2. contains the different wheels, &c. as after described, as will
be necessary for use when the machine is made with a worm or endless screw;
and in this Drawing the frame and wheels are calculated to supply the place
of the frame and wheels marked I, L, N, O, and P, in Drawing, Number One.
In this Drawing, namely No. 2., A denotes the frame to be used instead of
the frame I in Drawing No. 1. B, a grooved wheel or barrell to be used
instead of the grooved wheel or barrell L in Drawing No. 1. C, a cant wheel
of brass or iron attached to grooved wheel B in this Drawing, and receives
motion from the worm or endless screw D in this Drawing. D, a worm or
endless screw made of iron, on which is fixed the pinion E and
Drawing. E, the pinion of brass or iron fixed to the worm D. F, the fly to
be made of iron. G, the side cog wheel of brass or iron which gives motion
to the pinion E in this Drawing, and is worked by means of a winch and fly
wheel the same as in P, Drawing No. 1.
fly F in this
Drawing No. 3. shews the difference between the two former ways of making
the machine, and the one when the effect of working a barge or vessel without
horses or men to draw it is intended to be produced by means of lines or
chains, weights, and pullies. In this Drawing, namely No. 3., A denotes the
frame particularly described in letter A, Drawing No. 1. B, the main axle, on
and round which is to be placed iron gudgeons, brass or iron steps or sockets,
floats, joints or hinges, bolts or bolt spokes, and braces, as particularly
described in Drawing No. 1. and letters B, C, D, E, F, G, and H, therein.
C, in this Third Drawing, denotes two grooved wheels or barrells of wood or
iron fixed on the main axle. D, the wooden frame fixed in the barge or
vessel E in this Drawing, in which wooden frame the weights and pullies,
with two multiplying or grooved wheels, work. E, the barge or vessel. F, two
multiplying wheels, which, by means of the lines or chains G in this Drawing,
communicate with and set in motion the grooved wheels or barrells C in this
Drawing. G, the lines or chains mentioned in letter F in this Drawing. H,
a barrell to each of the wheels or barrells F on which the lines or chains I
wind and receive motion from the weight L in this Drawing. I, the lines or
chains mentioned in letter H in this,Drawing. K, the pullies, which are made
either of brass or wood, and may be worked two, three, four, or any given

page_text: number in a frame. L, the weights, made of iron or lead. M, an endless line
by which the barrell C in this Drawing is wound up when the weight or
weights is or are down. N, a grooved wheel or pulley attached to the barrell
H in this Drawing. O, an endless line by which that barrell may be wound
up. In working the machine, as described in Drawing No. 3, it is not abso-
lutely necessary to employ more than one set of weights; when, therefore,
one set only is used, it will be only necessary to have one.grooved wheel, as
mentioned in C, Drawing No. 3; one. multiplying wheel, F in the same Draw-
ing; one line or chain,G in the same Drawing; one barrell, H in the same
Drawing; one line or chain, I in the same Drawing; and one set of pullies, K
in the same Drawing.
In witness whereof, I, the said James Tremeere, have hereunto set my
hand and seal, the First day of April, in the forty-second 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 two.
Inrolled the Second day of April, in the year above written.
