PROVISIONAL SPECIFICATION left by the said William Edward Newton
at the Office of the Commissioners of Patents, with his Petition, on
the 22nd July 1874. .
I, WILLIAM EDWARD NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Civil Engineer, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN GAS BURNERS," to be
as follows:-
The object of this Invention is to effect a more complete and effectual
combustion of carburetted hydrogen gas than takes place in the burners
now in general use. This is effected by adapting to the upper end of

page_text: the burner a cylindrical cap made of metal, porcelain, or other refractory
material.
The Invention is applicable to various constructions of burners, but
the mode of adapting it thereto must of course vary according to the
peculiar construction of the burner.
For fish tail, bat wing, and other burners of that class, the cap may be
made to screw on to the stem of the burner, or it may be made to fit to
the cylindrical part, so that it may be raised or lowered thereon as may
be required.
For circular or Argand burners the cap may be simply allowed to
rest on the circular edge of the burner, or to embrace the cylindrical
part thereof. The stem of the burner is screwed or otherwise fixed in
the top of a small box or drum to which the gas is admitted from below.
The gas is admitted to this box or drum through two or more inclined
holes or short tubes, and on issuing from these latter strikes against the
top part of the drum, then descends and enters a drop tube, which is
practically an extension of the stem of the burner. It will thus be seen
that the gas does not pass direct from the supply pipe to the burner,
but first enters the drum where by the pressure it is rendered more dense,
and by being obliged to pass in a crooked or tortuous passage to the
burner the pressure is equalized.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Edward Newton in the Great Seal Patent
Office on the 22nd January 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM 2
EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the
County of Middlesex, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-second day of July, in the year
of our Lord One thousand eight hundred and seventy-four, in the thirty- 3
eighth year of Her reign, did, for Herself, Her heirs and successors, givo
and grant unto me, the said William Edward Newton, Her special
Licence that I, the said William Edward Newton, my executors, admi-

page_text: nistrators, and assigns, or such others as I, the said William Edward
Newton, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after 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 Inven-
tion for "IMPROVEMENTS IN GAS-BURNERS," being a communication-to-me
from abroad by Domenico Antonio Tesorieri, of Florence, in the
Kingdom of Italy, upon the condition (amongst others) that I, the
said William Edward Newton, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and
seals, 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 Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said William Edward Newton, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the Drawing here-
unto annexed, and to the letters and figures marked thereon (that is
to say):-
The object of this Invention is to effect a more complete and effectual
combustion of carburetted hydrogen gas than takes place in the burners
now in general use. This is effected by adapting to the upper end of
the burner a cylindrical cap made of metal, porcelain, or other refractory
material, and in so constructing other parts of the burner that the gas
may be compressed to a certain extent before it issues from the exit
openings to be consumed.
The Invention is applicable to various constructions of burners, but
the mode of adapting it thereto must of course vary according to the
peculiar construction of the burner.
For fish tail, bat wing, and other burners of that class, the cap may be
made to fit to the cylindrical part, so that it may be raised or lowered
thereon as may be required.
For circular or Argand burners the cap may be simply allowed to rest
on the circulas adme of the humer or to embrace the cylindrical nart

page_text: .
thereof. The stem of the burner is screwed or otherwise fixed in the
top of a small box or drum to which the gas is admitted from below.
The gas is admitted to this box or drum through two or more inclined
holes or short tubes, and becomes to a certain extent compressed in this
box or drum. On issuing from the short tubes or inclined holes the gas
strikes against the top part of the drum, then descends and enters a
drop tube, which is practically an extension of the stem of the burner.
It will thus be seen that the gas does not pass direct from the supply
pipe to the burner, but first enters the drum where by the pressure it is
rendered more dense, and by being obliged to pass in a crooked or tortuous
passage to the burner the pressure is equalized.
The construction or arrangement of the parts of this drum may be
considerably varied, as shewn in the accompanying Drawings, in which
Fig. 1 is a vertical section, drawn full size, of an Argand burner, with
the improvements adapted thereto; Figures 2, 3, and 4 are similar views
of fish tail or bat wing burners constructed according to the Invention.
In Fig. 1 a, a, is an Argand burner, the upper part of which may be
constructed of porcelain or other refractory material, and is perforated
with very fine holes for the exit of the gas. On the upper part of the
burner is fitted the porcelain cup b, which is provided with an clastic
fitting or spring 6*, so that it may be slidden up or down the tubular
part of the burner, and yet allow a small current of air to pass diametri-
cally. Across the upper end of the cap 6 may be fixed in suitable notches
a thin strip of platinum, and the lower part of the burner is enclosed
within a perforated cup or cover c through which air is admitted to
support combustion. The gas before passing to the burner enters a
cylindrical box or drum & of peculiar construction through two or more
short tubes e, e, and escapes therefrom by another tube f, which con-
ducts it to the burner. This cylindrical box or drum & serves to
compress the gas as it enters the drum by the tubes e, e, and from thence
it issues up the exit tube to the burner.
Fig. 2 is a vertical section of the same construction of drum adapted
to a fish tail or bat wing burner. It also shews a modification in tho
manner of adapting the porcelain cap to the burner. The cap is in this
instance made with a bottom, in the centre of which is a hole sufficiently
large in diameter to admit of being freely raised or lowered on the tubo
which leads to the burner, and at the same time allow of sufficient space
round the tube for the admission of air to the interior of the cap. The

page_text: cap is secured at any requisite height by a small thumbscrew m, which
when tightened up will make the cap fast, and at the same time allow
of the passage of air to the burner through the opening n.
Fig. 3 shews a modification of the interior of the drum in which the
gas enters by the inlet pipe h, strikes against the false bottom i of the
inside case 1, then passes by the openings k, k; into the interior of the drum,
from which it finally escapes to the burner up the pipes. This Figure also
shews a further modification of the manner of adapting the peculiar cap
to the burner. In this arrangement the cap is also made with a bottom, in
the centre of which is a hole which is tapped and made sufficiently large
to admit of the passage of the tube leading to the burner. This latter
has a screw thread formed on the periphery, which takes into a female
screw tapped in the hole in the bottom of the cap, so that the cap may
be adjusted to any height. In order to admit air to the interior of the
cap holes or perforations g, g, of any suitable shape or dimensions may
be made in its sides.
Fig. 4 shews the cap 6 applied to the burner as in Fig. 3, and the
drum & constructed as shewn in Fig. 2.
Having now described the Invention of " Improvements in Gas
Burners," as communicated to me by my foreign correspondent, and
having explained the manner of carrying the same into effect, I claim as
the Invention secured to me by Letters Patent as aforesaid,―
The application to gas burners of the adjustable cap 6 as and for
the purposes herein set forth.
I also claim the cylindrical box or drum & for the purposes herein set
forth.
In witness whereof, I, the said William Edward Newton, have here-
unto set my hand and seal, this Twenty-second day of January,
