Year: 1835

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ELIAS
CARTER, of the City of Exeter, Gentleman, send greeting.
WHEREAS His present most Excellent Majesty King William the Fourth,
by. His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Twenty-second day of June, in the fifth year of His reign,
did for Himself, His heirs and successors, give and grant unto me the said
Elias Carter, His especial license, full power, sole privilege and authority,
that I, the said Elias Carter, my exors, admors, and assigns, or such others as
I, the said Elias Carter, 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, uso, exercise, and
vend, within England, Wales, and the Town of Berwick-upon-Tweed, my
Invention of "AN IMPROVED APPARATUS FOR REGULATING THE SUPPLY OF GAS TO
THE BURNERS, AND FOR STOPPING OFF THE SAME; APPLICABLE ALSO AS A COCK IN
DRAWING OFF OR REGULATING THE FLOW OF OTHER FLUIDS;" in which said Letters
Patent is contained a proviso that I, the said Elias Carter, shall cause a
particular description of the nature of my said Invention, and in what manner
the same is to be performed, to be inrolled in His said 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.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Elias Carter, do hereby declare the nature of my said Invention, and the

page_text: DESCRIPTION OF THE DRAWING.
Fig. 1 represents my improved apparatus affixed to a gas burner; Fig. 2
is a longitudinal section of one of the said apparatuses shewn separately, and
is intended to be screwed or otherwise fastened to any tube through which
gas or other fluid is to be passed, and the flow of which is required to be
regulated or stopped off. Fig. 8 is a plan of Fig. 1; and Fig. 4 is a side
view of the same apparatus. In each of these Figures the same letters
indicate similar parts, a, a, being the tube or way for the flow of the gas;
b is a partition formed within the tube a, thus dividing the tube into two
chambers or parts; c is an opening formed in the tube a, the upper portion
thereof is of a circular form, which is the shape I prefer, but do not confine
myself thereto. This arrangement is clearly shewn in Fig. 3, the valve being
removed in order to shew the construction. The valve by which the opening
c is closed or contracted consists of a flexible material c, fastened by a screw
or other means to the part shewn in the section at m, which covers completely
the opening c, and which for gas apparatus and for purposes where the
chemical properties will not injure the same, I use leather which is screwed
to the part m, and the leather valve is affixed gas-tight over the recess formed
on the tube a, a, as is clearly shewn in the various Figures in the Drawing.
It will thus be evident that gas or other fluid passing in the direction of the
arrows will, when the valve e is off its seat, pass over the partition b, and then
pass off from the other end of the tube a; but such gas or other fluid will be
prevented passing in any other direction by the valve e being fixed all round,
and gas-tight at its edges. g is a metal cover which carries the handle h.
This handle has a screw i by which it is forced into or withdrawn from its
seat or opening c; attached to the part m is a socket f; on the other end of the
screw is formed a head which turns easily in the socket f, consequently is
capable of lifting the valve from or closing it over the opening c; the handle
I prefer to be moveable, and therefore have omitted it in Fig. 1.
Having thus described the arrangement of the apparatus, and the manner
of combining the same, I would remark that I usually cast the tube a, a, in
one piece, as is shewn in the Drawing; but I do not confine myself thereto,
for it will be evident that a similar arrangement may be added to an ordinary

page_text: piece of tube; and I would further remark that I do not confine myself to the
use of the leather as the flexible material for covering the opening c.
What I claim as my Invention is, the combining the flexible valve e of any
suitable material with a tube a arranged as above described into an improved
apparatus for regulating the supply of gas to the burner, and for stopping off the
same; applicable also as a cock in drawing off or regulating the flow of other
fluids.
In witness whereof, I, the said Elias Carter, have hereunto set my hand
and seal, this Tenth day of December, in the year of our Lord One
thousand eight hundred and thirty-five.
