PROVISIONAL SPECIFICATION.
Improvements in or Connected with Lamps and Burners for Lighting
and Heating Purposes.
I, RICHARD NICHOLLS, of 21 Sunningfield Road, Hendon, Middlesex, Gentleman,
do hereby declare the nature of this invention to be as follows:-
The globe is formed with an opening at top covered by wire guaze, and a
prolongated stem or flue at bottom by which it can be supported by resting upon a
gallery attached to burner or be otherwise suitably connected to the lamp fittings.
The burner is arranged somewhat on the Argand principle, so as to give a partially
round duplex flame, the two flames being arranged to meet together draw into the
flames a large amount of air; within the flames is arranged a ball of suitable material
to act as flame spreader, and deflector, as hereafter described, to assist the lighting
and heating. Between parallel duplex flat flames arranged a plate of suitable
material to assist the lighting and heating.
Over the top of flames is arranged a convex deflector and spreader-above referred
to as "a ball "this is held under the concavity of a second concave deflector arranged
above the first one.
These two deflectors may be made separately or in one, and are suitably attached
to or held by the lamp fittings or burner. In place of the duplex flames I may use
an ordinary Argand burner, in which case, the apex of the convex or lower deflector,
could terminate in a stem passing down inside of flame, and be used as a support to
attach the deflector to the burner by.
When using this invention for heating purposes the burner and accessories can be
arranged in an ornamental glass or other stove with suitable ornamental exits for the
light to show through and heat escape. Owing to the very perfect combustion that
is effected by means of burners and accessories constructed according to this inven-
tion, gas stoves can be used in rooms without injury to health.
Deted this 18th day of December 1888.

COMPLETE SPECIFICATION.
Improvements in or Connected with Lamps and Burners for Lighting
and Heating Purposes.
I, RICHARD NICHOLLS, of 21 Sunningfield Road Hendon, Middlesex, Gentleman,
do hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained, in and by the following
statement :-
The salient feature of the invention relates to the use in combination with suitable
burners, of a novel form of flame spreader which is also a deflector used in combina-
tion with a second deflector, whereby more perfect combustion of gas is obtained
combined with high illumination.
To enable my invention to be properly understood, I will proceed to fully describe
the same by aid of the accompanying drawings.

according to this invention.
Figure 2, similar view with modification of part.

Aame burner

Figures 7 and 8, detached views of gas regulator.
A, represents a white porcelain pottery ware or enamelled metal cup, preferably
glazed on the outside, acting as a flame spreader and deflector, this is held under
the concavity of a second deflector B; these two deflectors are supported over the
gas burner C, by a vertical rod D, secured to base of burner carrying screw nuts E,
suitable holes being formed in the deflectors for the rod D, to pass through.
These two deflectors are arranged as shown in drawings so that they present their
convex and concave sides to the flame. Instead of making the deflectors A, and B,
in two parts as described they can be made in one piece as reprosented at figure 2,
the lower portion A', corresponding to part A, and B₁, to part B. By holding B,
or B', with its concave side to the flame, forms a chamber F, for air, which becoming
heated by the heat of the deflectors and gas flame, greatly improves the combustion
and increases the illumination of the light. The burner and its accessories can be
used in the open air but is preferably covered by a globe G, as at figure 1.
This globe is held in a usual gallery H, connected to the burner, nitted at bottom
with a wire gauze H₁, the top of the globe being also covered in by wire gauze H³.
The latter carries off any cross draught of air, and prevents down draughts of
cold air.
The burner used with this invention may be of the ordinary "Argand " type, but
we have found that a modification of this such as is shown at figures 3 and 4, gives
better results. By arranging the burner to give a duplex flame and preferably
crescent shaped, allows a larger quantity of air to be drawn into the flame, which by
aid of the deflectors A, and B, further increases the combustion.
Or in place of crescent shaped duplex flames, we may use the forin of burner shown
at figures 5 and 6, which gives flat arched shaped duplex flames. In this latter arrange-
ment, a flat deflector 1, of white glazed pottery ware, is attached to the burner to be held
between the flames. The two latter arrangements of burners is found to give good
results for heating purposes, as they diffuse a large amount of heated air with a very
low consumption of gas.
In the carrying out of this invention, it is advisable to use an automatically acting
gas governor to enable the gas to be fed to the burner at a uniform pressure and
below that of the main. For this purpose I may use the regulator described in the
specification of my Patent No. 10014 of 1888, embodied in the drawings of this
present specification at figures 1, and 2, and shown detached at figure 7.
This regulator consists of a bent over tube K, connected to a plate K¹, which is
arranged to screw into a suitable holder K³, to which the supply pipe is attached.
This bent tube has holes K³, opposite to each other on the inside of each upright
part. Instead of this arrangement, I may make the holes on the outside as shown at
figure 8. The principle of this regulator as shown at figure 7 is first to divide the
main pressure into two columns by means of the two upright tubes and to bring the
two columns of pressure in opposition to each other, and to form the exit for the gas
from the two columns below where they meet together at top. This regulator is
covered by a chamber L, screwed on to the holder K³. The top of the chamber Lis
arranged for the stem of burner to screw in. Under the bottoni of burner stem in top
of chamber L, are two layers of wire gauze M, with a layer of linen N, between.
Into this chamber L, the gas from the regulator enters and mixes together, which
entirely breaks up the main pressure and enables the gas to pass to burner in an
even distribution and at a considerably less pressure than it is in the main.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1-The combination with a suitable gas burner. of deflectors held over flame and

page_text: arranged to present a convex and concave surface to the flame, substantially as
described and illustrated in the accompanying drawings.
2-The combination with deflectors held over gas flame and arranged to present a
convex and concave surface to the flame, of a duplex crescent shaped burner, as
described and illustrated in the drawings at figures 3, and 4.
3-A duplex arched shape flat burner having a flat deflector held between the
flames and parallel with same, as described and illustrated in the drawings at
figures 5 and 6.
4-The combination with gas burners, of a globe to surround the burner having
the top covered by wire gauze or finely perforated metal, as described and illustrated
in the accompanying drawings at figure 1.
