page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JACOB
BRAZILL, of Great Yarmouth, in the County of Norfolk, Gentleman, send
grecting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent, under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Fourth day of
'September, in the fifty-third year of His reign, give and grant unto me,
the said Jacob Brazill, during the term of years therein mentioned, should
and lawfully might make, use, exercise, and vend, within England, Wales,
and the Town of Berwick-upon-Tweed, my Invention of "A MACHINE TO WORK
CAPSTANS AND PUMPS ON BOARD SHIPS, WHICH MACHINE MAY ALSO BE APPLIED TO
VARIOUS OTHER USEFUL PURPOSES;" in which said Letters Patent there is con-
tained a proviso obliging me, the said Jacob Brazil, by an instrument in
writing under my hand and seal, to cause a particular description of the
nature of my said Invention, and in what manner the same is to be performed,
to be inrolied in His Majesty's High Court of Chancery within two calendar
months after the date of the said recited Letters Patent, as in and by the
same (relation being thereunto had) will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Jacob Brazill, do hereby declare that the nature of my said Invention, and
manner in which the same is to be performed, are particularly described and
ascertained in manner following, that is to say:-
In the Drawings or Figures hereunto annexed, Fig. 1, a, b, represents the
spindle or axis of the capstan of a ship or vessel, having fixed thereon a wheel

page_text: of small diameter with level or oblique teeth, of the proper figure to be acted
upon and worked by the worm or screw C, which last is fixed upon the cross
axis or arbor e, e; and at the extremities e, e, are handles for working the
same; and at any fit place or places upon the said axis or arbor I fix one or
more fly or balance wheels d, d, for the purpose of governing and equalizing
the motion; and by means of the said machinery I do work the capstan when
required. is a wheel with contriate teeth, likewise fixed upon the capstan
spindle, and serving to drive the wheel 9 upon a cross arbor h, i, which termi-
nates in cranks or handles, or the like eccentric connection applied to the
purpose of working one or more pump or pumps d, d, by their respective
pump rods; and I do accordingly work the said pump or pumps thereby, and
the said pumps may be worked either upon the upper decks or between decks,
or ŏrwise, by means of well-known mechanical connections; any pumps or
other gear may be worked at a distance from the said machinery for any other
useful purposes. And further, in the said Drawings, Fig. 2 represents the
spindle of the capstan separately and apart. Fig. 3 is the capstan itself.
Fig. 4, a plate to be put above the top of the capstan when on the spindle,
and securely pinned or bolted there. c, in Figure 2, is a shoulder for the
wheel Fig. 16, into which the worm of Fig. 1 works. Fig. 6 is a hard
metallic ball, upon which the heel of the capstan spindle (Fig. 2) rests and
turns. Fig. 7 is a socket for the spindle. Fig. 8 is a cell for the ball. Fig. 9
is the contrate wheel marked fin Fig. 1. Fig. 10 is the wheel marked g in
Fig. 1. Fig. 11 is a wheel for a chain pump, which may likewise be fixed
and used upon the cross arbor or axis h, i, of Fig. 1. Fig. 12 is the same
cross axis. Fig. 13 is the fly wheel. Fig. 14 is the first moving cross axis,
with its worm and an handle, shown at one end at Fig. 15. Fig. 16 is the
small wheel for the worm, as before mentioned. Fig. 17 is the rod and upper
bucket of one of the pumps, the rod being pointed at N to follow the crank,
and slit or divided at M to work upon the cross rod or bar p, in Fig. 18.
Fig. 18 is the upper part of one of the pump barrels. Fig. 19 is the same,
but provided with a cap G, Fig. 20, thro' which the rod works by a stuffing
box, and which is fitted up like the air vessel of an extinguishing engine, with
a pipe and mozles, and renders the pump capable of being used for the pur-
poses of an engine of that description. Fig. 21 and 22 are two bevel cog or
spur wheels which are fixed on the capstan and fly spindles, if required, to act
in the places of Fig. 14 and Fig. 16, at c.
And lastly, I do declare that my said Invention, as to the several parts
thereof, and the respective demensions and positions of the same, and the useful
purposes to which the same may be applied, are capable of being much varied
