Year: 1848

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
FREDERIC BATEMAN, of Manchester, in the County of Lancaster, Civil
Engineer, and ALFRED MOORE, of the same place, Civil Engineer, send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Eighteenth day of January, in the eleventh year of Her reign, and
in the year of our Lord One thousand eight hundred and forty-eight, did, for
Herself, Her heirs and successors, give and grant unto us, the said John
Frederic Bateman and Alfred Moore, Her especial license, full power, sole
privilege and authority, that we, the said John Frederic Bateman, and
Alfred Moore, our executors, administrators, and assigns, and such others as
we, the said John Frederic Bateman and Alfred Mcore, our executors,
administrators, 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, within
England and Wales and the Town of Berwick-upon-Tweed, our Invention
of "CERTAIN IMPROVEMENTS IN VALVES OR PLUGS FOR THE PASSAGE OF WATER OR
OTHER FLUIDS;" in which said Letters Patent is contained a proviso that we,
the said John Frederic Bateman and Alfred Moore, or one of us, shall cause
a particular description of the nature of our said Invention, and in what
manner the same is to be performed, to be enrolled in Her Majesty's High
Court of Chancery within six calendar months next and immediately after the
date of the said in part recited Letters Patent, as in and by the same, reference
being thereunto had, will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
John Frederic Bateman, on behalf of myself and of the said Alfred Moore, do
hereby declare the nature of our said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement and the Drawings hereto annexed (that is to
say):
=
Our Improvements in Valves or Plugs for the Passage of Water or other
Fluids apply principally to cocks or valves used for drawing off water from
the main or service pipes of water works for the supply of mills, works, or
buildings for the extinction of fire, the watering of roads, streets, or gardens,
the irrigation of land, the cleansing of water pipes, the flushing of sewers, and
other similar purposes, and relate,
First, to the use and application for the purpose of drawing off water or
other liquids, of a valve (of a globular or other form) of a specific gravity
lighter than water, and constructed of or covered with vulcanized india rubber,
gutta percha, or other compressible elastic substance, the closing of such valve
being effected by the pressure of the water.
Secondly, to the use and application for the same purposes of a valve of a
globular form, of the same or greater specific gravity than water, constructed
or coated as above described, and closed in a similar manner.
Thirdly, to opening valves for the passage of fluids by means of a moveable
opening key, consisting of a hollow tube or pipe, with proper adjuncts, so
applied as without the aid of any thread or screw upon the barrel, or any fixed
part of the valve itself, or the parts necessarily permanently connected there-
with, to force the valve open against the pressure of the fluid, the key or tube
being so constructed that the fluid, when released, shall pass off through the
said tube.
The practical application of our improvements will be readily understood
by referring to the Drawing accompanying these presents, in which, by way of
illustration, one mode of applying the opening key is exhibited as applicable to
a street cock or plug.
Fig. 1 shews our improved valve or cock in section, shewing also the open-
ing key or tube in elevation, and disconnected therefrom; Fig. 2 is a section
shewing the valve open and the opening key connected thereto; and Fig. 3 is
a front elevation of the valve box or barrel, and the opening key disconnected.
The Drawing is made about one fourth the real size, and has figures and
letters of reference marked thereon corresponding with the following expla-
nation thereof. a, a, is the branch or connecting pipe from the water "main,"
to the flange of which is bolted the valve box b, b, the neck of which is closed

page_text: by means of the globular valve c, formed of or coated with vulcanized india
rubber, gutta percha, or other compressible elastic material, the pressure of
the water being sufficient to keep the valve closed. d, d, is the discharge or
drawing-off tube, which is furnished at its upper end with a screwed nozzle e,
for screwing on the hose pipe. f, f, is a bracket fixed upon the elbow of the
pipe d; this bracket carries the internal screwed nut g (see Fig. 2), which
turns loosely therein, but is kept in its place by a pin h (see Fig. 1), working
in a groove upon the outside of the nut g. Upon the upper part of the nut g
is fixed the winch handle i. k is a screw, the upper part of which works in the
nut g, the lower part being squared and working through the guide 1. At the
lower end of the screw k is attached by a joint the catch m. When it is desired
to discharge or draw off water from the "main" through the the plug or cock,
the opening key is taken to the plug, and the part n thereof is lowered into
the neck of the valve box b, b, until the lower end of the tube rests upon the
valve c, at the same time that the lower end of the catch m (having been
sufficiently depressed prior to the insertion of the tube) passing outside or
sliding over the projecting rim p, upon the valve box, falls, by its own gravity,
under such projecting rim, thus locking or attaching the opening key or tube
to the valve box. The opening key being thus attached, the turning of the
winch handle i will force the tube downwards, and gradually depress the
valve c, when the water will flow freely around the valve and upwards through
the discharge tube d.
Fig. 2 shews the valve open. When it is desired to withdraw the opening
key or tube, and close the valve, the handle must be turned in the reverse
direction, which will allow the tube d to rise in the neck of the valve box b,
being forced out of the position shewn in Fig. 2 by the pressure of the water
acting on the ball or valve c; until the valve closes the aperture. The turning
of the winch handle being then continued, the projecting part q of the catch
acting against the flange r upon the discharge tube, will throw the catch into
the position seen in Fig. 1, when the key or tube may be withdrawn, the catch
passing clear of the rim p. The opening key may be attached to the plug or
cock in other ways, without the aid of screws, such as by projecting lugs or
ears, under or by means of which the opening key or the tube through which
the water is drawn off may be secured or connected, or in various other ways,
by which the same purpose would be effected, and which would readily suggest
themselves to a practical mechanic. The valve just described will allow of the
escape of air from water pipes by the falling or opening of the valve whenever
the water is not in contact with the valve, or the pressure sufficient to keep the
valve closed.

page_text: Having now described the nature and object of our said improvements, we
would remark, that we claim as our Invention,-
First, the application for the purpose of drawing or letting off water or
other fluids, of a valve, of a less specific gravity than water, constructed of or
coated with vulcanized india rubber, gutta percha, or other suitable compres-
sible elastic material, and which closes or is kept closed by the pressure of
the water.
Secondly, the application for similar purposes of a globular valve, of the
same or greater specific gravity than water, and constructed or coated as
above described, which, without mechanical aid, will close by the pressure of
the water.
Thirdly, the opening of valves by means of a key or tube, so applied as to
force the valve open against the pressure of the water or other fluid, and
through which key or tube the fluid escapes, such key or tube being attached
to the box or barrel or other fixed part of the valve without the aid of a thread
or screw on such box or other fixed part.
In witness whereof, I, the said Jobu Frederic Bateman, have hereunto
set my hand and seal, this Thirteenth day of July, One thousand
eight hundred and forty-eight.
Inrolled the Eighteenth day of July, in the year above written.

page_text: cation, was not the combination of parts which the Jury had found to be new
and to have been invented by us, but the several parts of such combination;
and whereas the said Lord Chief Baron, in delivering his said judgment,
suggested that the plaintiffs would do well to consider whether it might be
advisable to apply to the Law Officer of the Crown, to prevent that question
as to the Specification arising at any future time; and whereas we are desirous
to remove any such objection or doubt as to our Invention; and whereas we,
the said John Frederic Bateman and Alfred Moore, are desirous, for the
reasons aforesaid, to enter a Disclaimer and Memorandum of Alteration, as
herein-after contained and expressed, and have obtained leave of Sir Richard
Bethell, Knight, Her Majesty's Solicitor General, to enter such Disclaimer
and Memorandum of Alteration.
NOW KNOW YE, that we, the said John Frederic Bateman and Alfred
Moore, do hereby alter the said Specification by omitting the words "first,"
"secondly," and "thirdly" at the commencement of the claiming clauses at
the conclusion of the said Specification; and in place of the said word
"secondly," we do substitute the word "or," and in place of the said word
thirdly," we do substitute the word "and," so that the concluding paragraph
of the said Specification, as the same will stand when altered as aforesaid,
will be as follows:-
