page_text: LETTERS PATENT to John Sanders, junior, of Upper Hockley Street,
Birmingham, in the County of Warwick, General Gas Fitting and
Chandelier Manufacturer, for the Invention of "A NEW OR IMPROVED GAS
REGULATOR FOR CONTROLLING OR REGULATING THE FLOW OR PRESSURE OF GAS
REQUIRED TO BE USED FOR ILLUMINATING PURPOSES."
Sealed the 23rd August 1864, and dated the 23rd February 1864.
PROVISIONAL SPECIFICATION left by the said John Sanders, at the
Office of the Commissioners of Patents, with his Petition, on the 23rd
February 1864.
I, JOHN SANDERS, junior, of Upper Hockley Street, Birmingham, in the
County of Warwick, General Gas Fitting and Chandelier Manufacturer, do
hereby declare the nature of my said Invention for "A NEW OR IMPROVED GAs
REGULATOR FOR CONTROLLING OR REGULATING THE FLOW OR PRESSURE OF GAS
REQUIRED TO BE USED FOR ILLUMINATING PURPOSES," to be as follows (that
is to say):-
My Invention consists in providing, by preference, a circular chamber,
small or large, according to the position in which it may be required to be
used, the said chamber being contracted at the bottom, and fitted with a valve,

page_text: and which valve is connected by a wire or reduced neck to a thin metal disc;
the exterior of the chamber thus described is so fashioned or shaped and
arranged for screwing to or otherwise readily connecting with gas fittings, but
its compact and symmetrical form renders it exceedingly applicable to be
united to the arm at the lower end, and the burner at the top of ordinary
fittings, its action may be described thus, that according to the pressure of the
gas so the gravitating effect of the valve will be overcome, and the valve
elevated, thereby contracting the orifice through which the gas passes between
the periphery of the disc and the interior of the chamber into the vacant space
above, and from there to the burner, sufficient space being always provided,
that under the highest pressure a sufficiency of gas shall pass upward for
supplying the flame.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Sanders, in the Great Seal Patent Office on' the
23rd August 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
SANDERS, junior, of Upper Hockley Street, Birmingham, in the County
of Warwick, General Gas Fitting and Chandelier Manufacturer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-third day of February, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-seventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said John Sanders, junior, Her special license that I, the said John
Sanders, junior, my executors, administrators, and assigns, or such others
as I, the said John Sanders, junior, my executors, administrators, and
assigns, should at any time agree with, and no others, from time to time and
at all times thereafter during the term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention for
"A NEW OR IMPROVED GAS REGULATOR FOR CONTROLLING OR REGULATING THE
FLOW OR PRESSURE OF GAS REQUIRED TO BE USED FOR ILLUMINATING PURPOSES,"
upon the condition (amongst others) that I, the said John Sanders, junior,
by an instrument in writing under my hand and seal, should particularly
describe and ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great Seal

page_text: Patent Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said John Sanders, junior, do hereby
declare the nature, of my said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement (that is to say):-
My Invention consists in providing, by preference, a circular chamber,.small
or large, according to the position in which a regulator may be required to be
used, the said chamber being cylindrical, but contracted at the bottom, and
terminating with a valve chamber, which is fitted with a hollow or other
conical valve, and which valve is connected by a wire or reduced neck to a
thin metal disc which rests on the bottom of the upper chamber before
referred to; the exterior of the chamber part, thus described, is so fashioned or
shaped and arranged for screwing to or otherwise readily connecting with gas
fittings, either near the meter or main supply pipe, or any intermediate
position, according to its general size and requirement, but its compact and.
symmetrical form renders it exceedingly applicable to be united to the
extremities of chandelier arms or brackets, by the regulator being screwed at.
its lower end for that purpose, while the burner, which may be of any shape
or construction, argand or jet, may be applied at the top.
The action of this regulator may be described thus:-According to the
pressure of the gas, so the gravitating effect of the valve will be overcome, and
the valve elevated, thereby contracting the orifice through which the gas
passes between the periphery of the valve and the interior of the valve
chamber, and again between the periphery of the disc and top chamber, to
check and control the flow of gas, sufficient space being always provided that
under the highest pressure a sufficiency of gas shall pass upward for supporting
the flame, but my principal object is to so govern the flow of gas as to
prevent a long and extended flame being produced, as such a result is not only.
in many instances dangerous, but the gas is not properly consumed with such
high pressure, nor is the greatest light obtained, so that in use, if the full flow
way is open, by turning on the gas for that purpose, when the pressure is
excessive, the benefit of my regulator will be brought into action, as the valve
will be elevated, and the flow way of the gas contracted or nearly closed by its
force, in which case the ordinary gas tap or cock may be slightly turned, and
the desired pressure obtained for producing the best light with the least
consumption of gas.
But in order that my Invention may be best understood by referring to the
Drawings hereunto annexed, I will proceed to describe the same, aided by the.

page_text: Its
nuproved regulator, as applicable to an oramary пsu-tall burner.
modifications for adapting it to other positions or other burners will be well
understood by any ordinary workman acquainted with gas fittings.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a side view of a gas regulator constructed according to my
improvements. A is an ordinary fish-tail burner, united to the cap B, which
again is tapped and united to the body or chamber part C, which is secured in
like manner to the base part D, which terminates with an extended screwed
part E, for uniting it to gas brackets or fittings. Fig. 2 is simply a top view
of Figure 1; and Fig. 3 is a vertical section of Figure 1, showing the top
chamber with the disc also in section, marked g, soldered to a wire centre,
to which is united the conical valve h, which is right over the gas way
indicated by the arrow. In use, and according to the pressure, the force of the
gas lifts the disc g (which carries with it the valve h) and escapes between
the outer surface of the valve h and inner surface of the valve chamber, again
escaping beneath and around the periphery of the disc g to the chamber f,
from whence it flows to the burner A; the pressure of the gas (which has a
tendency to elevate the disc g) is partly counteracted by the weight of the
valve h. In case of great pressure the valve is so far elevated as to nearly
cut off the supply by its periphery coming in contact with the sides of the
valve chamber.
.
Thus it will be seen that under all the various and fluctuating degrees of
pressure to which gas is subject in its ordinary general use for illumination,
the said pressure will be sufficiently regulated by my improved self-acting
regulator, and which from its construction (after once applied) will require no
attention, nor is the means of regulation liable to any derangement or
deterioration in its action. Fig. 4 is simply a detached top and side view of
the disc g and valve h.
Having thus described my Invention, and the manner in which the same
may be carried into effect, and adapted for the several positions in which it
may be applicable for regulation in the conducting of gas for illumination, I
wish it understood that I do not purpose confining myself to the exact details
herein described, provided the general spirit of my Invention is preserved, as
it is clear the mode of connecting the top disc with the valve may be variously
effected, likewise the shape or amount of convexity given to the disc g, and in
like manner to the shape of the valve h, as also the mode of constructing and
putting together the various parts without affecting the general character of

page_text: my Invention; but what I claim and wish to protect by these my in part
recited Letters Patent is, the general combination as herein described and
exhibited.
In witness whereof, I, the said John Sanders, junior, have hereunto set
my hand and seal, this Twentieth day of August, in the year of our
Lord One thousand eight hundred and sixty-four.
