Year: 1782

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
HARPUR, of Leixlip, in the County of Kildare, Callico Printer, send
greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent, under the Great Seal of Great Britain, bearing date at
Westminster, the Sixteenth day of November, in the twenty-third year of
His reign, give and grant unto me, the said Thomas Harpur, His especial
licence, full power, sole privilege and authority, that I, the said Thomas
Harpur, during the term of years therein expressed, should and lawfully might
make, use, exercise, and vend, within England, Wales, the Town of Berwick-
upon-Tweed, and also in His said Majesty's Colonies and Plantations abroad,
my Invention of "A MACHINE FOR WATERING YARN OR CLOTH ON WHITSTERING
GROUNDS, CROFTS, OR CALLICO PRINTING GROUNDS;" in which said Letters Patent
there is contained a proviso obliging me, the said Thomas Harpur, by an instŕü-
ment in writing under my hand and seal, to particularly describe and ascertain
the nature of my said Invention, and in what manner the same is to be
performed, and cause the same to be inrolled in His Majesty's High Court of
Chancery within four calendar months next and immediately after the date of

page_text: the said Letters Patent, as in and by the said Letters Patent, reference
being thereunto had, may more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Thomas Harpur, do hereby declare that the nature of my said Machine for
Watering Yarn or Cloth on Whitstering Grounds, Crofts, or Callico Printing
Grounds, and the manner in which the same is to be performed, is par-
ticularly described in and ascertained in the manner following, that is to
say:
The construction or composition of my Invention of a Machine for Watering
Yarn or Cloth on Whitstering Grounds, Crofts, or Callico Printing Grounds,
consists of its wheels and carriage, its cask or reservoir for containing water, valves
to retain or let the water out at pleasure, pipes to convey the water from the
reservoir to the pumptree, and from the pumptree into the tubes or pipes, with
holes in 'em for spreading the water over the yarn or cloth, and the various
small appendages for supporting the pipes or tubes, and making the machine
compleat, which will be hereafter fully explained. This machine is to be
drawn by a horse or otherwise. The tubes project a considerable distance, about
fifteen or eighteen feet from the pumptree on each side; the horse with the
carriage moves along a road, on cach side of which cloth or yarn is laid. Over
this cloth or yarn the tubes project; and when the horse is set a-going, the
cask or vessel, being previously filled with clear water, the valves are then
raised, and the water descends upon the cloth or yarn. When the cask.or
reservoir is emptied, the valves are let down; it must again be fill'd with clear.
water. I have hereunto annexed a Drawing of the machine, and by references
thereto being had, its construction and principles will more fully and at large'
appear.
Figure 1 represents the machine drawn by a horse upon its movcablé
wheels and carriage; B, B, the wheels and carriage; C, the horse to draw the
machine; D, D, are two pieces of wood or upright posts, about 6 inches by 3
inches square, and about 6 feet long each, the lower ends of which are fixed
to the shafts a, a, by two screw bolts b, b. Those two upright posts are bound
together in different parts by. wood or iron bolts, so as to keep 'em from
moving at c, c, c, c. About a foot from the upper ends of those upright posts
two mortices are made, one in the fore and the other at the hinde side d, d
into which wood or spurrs e, e, are fitted, which are about 3 inches-sqro, and are
continued down to that part of the shaft or carriage marked f, f, and are
fastned to the carriage with screw. bolts g, g. E, E, are two sides of a
frame of iron, which is fastned to the shafts a, a, by nails or otherwise. This
frame is made of iron about an inch in breadth, and a quarter of an inch in

page_text: thickness. i is a cross bar, about 7 inches or 8 inches long, rivetted to each
side; jis the lowest bar, which has a little hole at each end, which goes on
to the iron pikes k, k, which are part of the side of the frame E, E. Upon
these pikes are screws and nutts, which serve to raise the lower barr j.
Betwixt these two bars is put a pumptree, or hollow piece of wood C, C, and
by screwing the nutts fast is holden there, so as not to be moveable. The
bore in the pumptree is 4 or 5 inches diameter, and about 7 foot long, into
each end of which is fixed a pipe or tube A in Fig 2, as at B, 16 or 18 feet
long, and down in such a manner as to be perfectly air-tight. When the horse
is in the carriage, the lower part of the iron frame E, E, Fig 1" should be
about 18 inches from the ground.
Figure 2 represents a front view of the said machine. Z is the pumptree,
into which the pipes or tubes A, A, are fixed. The pipes or tubes A, A, are
thus made:-I take 3 boards, about 5 inches broad, as p, Fig 3d; in the lower
or under part is left a cavity or opening betwixt the boards of about. of an
inch or less, as g. Over this cavity or opening I nail a very thin piece of copper
or other metal, which has a row of holes made along its middle from one end
to the other, as in Fig 3, X; those holes are about the size to admit of an
ordinary pin, and about 8 or 10 in an inch; the end farthest from the carriage
is made up fast, and the end that communicates with the pumptrée is quite
open. K, K, are two pipes of 6 inches wide and 9 inches long, made of
wood or metal, and fixed tight into the pumptrec, so as to communicate with
its inside; L, L, are two other pipes of the same size and sort as K, K, only
9 inches long, and are fixed in the under part of cask O at n, n, which pro-
jects S or 4 inches into the cask or reservoir, and are made quite tight; S, S,
are two valves fitted to the upper part of the pipes n, n, and made water-
tight, so as to prevent the water flowing out of the cask O; t, t, are two leather
pipes of about 16 inches or 18 inches long, one end of which is put upon the
pipes L, L, and the other other ends upon the pipes K, K, and are fast tied
thereto with cords; these pipes make a communication betwixt the cask O
and the pumptree. W, W, are two cords or chains, which are fixed to the
valves S, S, and are brought out at the top of the cask O at y when the
cask O is filled with water; by pulling at the cords or chains W, W, the water
descends through the pipes L L, leather pipes t, t, and pipes K, K, into the
pumptree, and from thence into the large pipes or tubes, and from thence fall
through the small holes in copper or other metal on the lower side the tube in
the form of a shower. v, v, v, v, are iron rods about of an inch square, with
their lower ends made like hooks. k, k, k, k, are staples nailed to the tubes
or pipes, into which the hooks at the lower end of the iron rods are fastnet.

page_text: Those rods or braces go from the pipes and through the sides of the upright
posts D, D, Fig 2. At the upper end of those rods are screws and nutts,
which serve to tighten or slacken 'em occasionally, as the pipes or tubes are
wanted at a greater or less distance from.the ground. u, u, are two iron rods
about 4 or 5 foot long and about of an inch square, one end of which are 5
fastned to the ends of the axle Q, the other ends are fastned: to the back part
of the tubes or pipes. Those rods are intended to keep the tubes from.moving
forward or backward. G is a partition fixed in the centre of the pumptree Z
to prevent the water communicating from one end to the other. The cask. O'
is fastned upon two chorks, which are bolted to the carriage.
The cask, reservoir, or cestern for the water, as well as the carriage, pipes,.
valves, pumptree, tubes, &c., may be made of all sizes and in all. forms; and: of
any kind of materials that casks, reservoirs,.cesterns, valves,. pipes, pumptrees,.
tubes, troughs, &c. generally are or can be made of.
In witness whereof, I, the said Thomas Harpur, have hereunto set my
hand and seal, the Twenty-eighth day of January, in the year of our
Lord One thousand seven hundred and eighty-three.
