PROVISIONAL SPECIFICATION.
Improvements in Means for Increasing the Illuminating Power
of Lamp Flames.
I GEORGE Moss, of Constitution Hill, in the City of Birmingham Manu-
facturer do hereby declare the nature of this invention to be as follows:--
This invention relates to improvements in apparatus by which the flame of a
lamp burner is increased or intensified, and consists as follows:-
At present the following means are adopted to effect this object, that is to say,
upon each side of the flame is placed an impinging plate, whose upper edges are
more or less curved, and permitting a considerable opening at each end for air &c.
It is at these ends or openings that 1 provide my improvements, thus:-1 carry
upwards from a suitable base, and upon each side, a rod or strip, to nearly the
top of the aforesaid impinging plates. These are now formed into a gutter or
grooved shape, or a plate fashion, and pass inwards between these plates, towards
and upon the flame.
By these means the flame is much increased in size and intensity. These end
wings or deflecters may be formed in one piece with those forming the side
impinging plates, or they may be separate and distinct therefrom.
Dated this 10th day of December 1892.

COMPLÈTE SPECIFICATION.
Improvements in Means for Increasing the Illuminating Power
of Lamp Flames.
I GEORGE Moss, of Constitution Hill, in the City of Birmingham, Manu-
facturer, 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 :-
This invention relates to improvements in apparatus by which the flame of a lamp
burner is increased or intensified.
At present the following means are adopted to effect this object, that is to say,
upon each side of the flame is placed an impinging plate, whose upper edges are
more or less curved, and permitting a considerable opening at each end for air &c.
It is at these ends or openings that I provide my improvements, thus:-I carry
upwards from a suitable base, and upon each side, a rod or strip, to nearly in line
with the top of the aforesaid impinging plates. The outer end portions of these
rods or strips are now formed into a gutter or grooved shape, made to pass inwards
between the side plates, towards and against the flame, thus forming end impinging
plates.
I will now proceed to more particularly describe this my invention, by the aid of
the accompanying sheet of drawings, upon which are figures and numbers of
reference, similar numbers referring throughout the several views to the same thing
or part, and in which :-
Fig. 1, is a view of a suitably shaped blank of sheet metal from which my
invention is formed.
Fig. 2, is a front elevation, Fig. 3, an end elevation and Fig. 4, a plan view of this
my invention.
I cut out a blank 5, of sheet metal, in the centre of which is a hole 6, of suitable
Price 8d.1

page_text: shape and size to pass onto the wick tube 7, of the lamp burner. The sides 8, 8,
of the blank 5, are made concave in shape and bent upwards, so that the concave
surfaces come opposite to each other, and thus form the side impinging plates.
The end portions 9, 9, of the blank 5, are now bent upwards, somewhat of
a S shape, which forms the spring clips 10, 10, which rest against the wick tube 7,
and assist in holding the apparatus securely in position. These end portions 9, 9,
are further continued upward and cutwards, thus forming the end impinging
plates 11, 11, to which the flame clings and thereby spreads itself. These plates
are further formed of a gutter or grooved shape as shown, which assists such
clinging and spreading of the flame.
The side and end impinging plates are somewhat cut away at their lower
portions 9ª, thus increasing the size of the openings 12, 12, for the admission of air to
the flame. By means of this apparatus the flame as before intimated is inclined up
along the end impinging plates 11, 11, thereby much increasing the size and
intensity of the flame.
If desired the end impinging plates 11, 11, and the spring clip portions 10, 10,
instead of being formed in one with the side impinging plates 8, 8, may be made
separate, and attached thereto by rivetting or otherwise..
Although I have shown the end plates 11, 11, and clips 10, 10, of the shape
illustrated, I do not confine myself to this particular shape, as they may be varied
if desired.
I am aware that prior to this my invention, flame spreaders have been used
having concave side plates similar to those shown at 8, 8, upon the drawings, and
therefore I do not wish to claim these broadly, but,
Having now particularly described and ascertained the nature of this my inven-
tion, and in what manner the same is to be performed, I declare that what I
clain is :-
In apparatus for increasing the illuminating power of the flame of a burner, the
combination with the side impinging plates 8, 8, of the end plates 11, 11,
constructed and arranged as described and shown.
