Year: 1811

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
GOOD, of Coleman Street, in the City of London, Plumber, send greeting.
WHEREAS His most Excellent Majesty King George the Third, by His
Letters Patent under the Great Seal of the United Kingdom of Great Britain
and Ireland, bearing date at Westminster, the Ninth day of September, in the
fifty-first year of His reign, did, for Himself, His heirs and successors, give
and grant unto me, the said William Good, my exors, adiñors, and assigns,
His especial licence, full power, sole privilege and authority, that I, the said
William Good, my exors, admors, and assigns, or such others as I, the said
William Good, my exors, admors, or assigns, should at any time agree with,
and no others, from time to time and at all times during the term of years
therein expressed, should and lawfully might make, use, exercise, and vend,
Invention
within England, Wales, and the Town of Berwick-upon-Tweed, my
of "AN IMPROVEMENT IN VALVES FOR VARIOUS PURPOSES;" in which said Letters
Patent there is contained a proviso, obliging me, the said William Good, 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 cause the same to be enrolled in His Majesty's High Court
of Chancery within two calendar months next & immediately after the date
of the said recited Letters Patent, as in and by the same, reference being
thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William Good, do hereby declare that the nature of my said Invention, and the
manner in which the same is to be performed, are particularly described and
ascertained as follows, that is to say :-

page_text: In the Drawing hereunto annexed, A, B, C, D, represents a stem or
tube or pipe, proceeding from any receptacle or vessel or place containing
water or any other dense fluid; and E, F, G, represents a nozzle or tube
or pipe screwed or fixed by any other fixed means unto A, B, at the part
C, D, and the said two pieces in the combination here represented do
constitute the shell or external part of an apparatus found to serve the
purpose of a cock. H, I, represent a spindle valve ground and fitted to
the mouth of E, F, and capable of being lifted by the lever F, which
moves on the centre or axis L, by means of an external piece or handle or
head. M is an upright pin, which being fixed serves to guide the valve
H, I, up and down in the vertical direction, and prevents its tilting to one
side, at the same time that the upper part N of the piece A, B, prevents the
same from removing too far from its seat; or otherwise the said pin may be
screwed or fixed at the opposite part at N, and the tail of the valve perforated
downwards from 0 to a sufficient depth, but not quite through. "And I do
farther declare that my said improvement in valves is. not only. applicable..to
the purpose of cocks for drawing off water, and for other uses, but may also
be introduced upon the large scale in public water-works and the like, in which
whenever it may be found convenient to place the valve H, I,. with the water.
way thereof horizontal instead of vertical, there may be a counter spring.
placed between M and O, and the same expedient may be used whenever the
handle of L is required to stand upright, or vertical; and farther, that instead of
raising the valve by the lever K, the same effect may be produced by a wedge
or chamfered piece. And I do moreover declare that the said valve may be
made to remain permanently open, or permanently shut, at pleasure, by making
the pin L move stiff by a spring binding or otherwise, and that the tail K may:
easily and obviously be made to draw the said valve down as well as push it
up. And farther, that whenever the said apparatus is intended to regulate the
filling of any vessel with water; a float may be attached to the pin or axis L by
means of a lever towards F, which shall descend by its weight when the vessel
is partly or wholly empty, and rise by its floatage when the vessel shall be duly:
filled, and shall by that means produce the effect of a ball-cock, but with
greater speed and certainty than are commonly obtained by those instruments.
In witness whereof, I, the said William. Good, have hereunto subscribed
and set my hand and seal, the Twenty-third day of October, in the year
of our Lord One thousand eight hundred and eleven.
W GOOD. (L.S.)
