PROVISIONAL SPECIFICATION.
Improvements in Gas Lighting Apparatus.
I EZRA HATTON 110 Sackville Street Manchester Engineer do hereby declare
the nature of this invention to be as follows:-
The object of my invention is to produce a gas light with a steady flame of high
illuminating power, and one which will prevent the deposition of carbon on the
reflectors which are placed over the flames, and one also which can be used for
ventilating lights.
My invention is carried into effect as follows: A metal gas bulb is formed
with any desirable number of jets, placed at an inclined angle, over the centre of
which is fixed an inverted vase, or frustrum of a cone and on the top of this is fixed
one or more dish shaped, or flat conical reflectors, according to the size and
number of jets required, an adjustable space is arranged between each reflector as
an outlet for the gas products, the vase and reflectors are enamelled or coloured
white, and may have attached a larger shade or reflector for diffusing the light and
collecting the gas products and vitiated air.

COMPLETE SPECIFICATION.
Improvements in Gas Lighting Apparatus.
I EZRA HATTON Engineer 110 Sackville Street Manchester, 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 object of my invention is to produce a gas light with a steady flame of
high illuminating power and one which will prevent the deposition of carbon on
the reflectors which are placed over the flames, and one also which may be used
for ventilating lights.
My invention is carried into effect as follows:-A metal gas bulb is formed
having any desirable number of jets which are placed at an inclined angle, over the
centre of this gas bulb is arranged one or more enamelled reflectors, which may be
dish or saucer shaped, conical or any other section, according to the size and
number of jets required; an adjustable space is arranged in and between each
reflector as an outlet for the gas products; when used as a ventilating light the
whole of the gas products are carried up the ventilating tube, and the heat from
the burner utilized for increasing the exhaust.
Fig. 1. A is a saucer shaped enamelled reflector with an outlet at the top. B is
a similar reflector to A but smaller. C is the gas bulb with jets fixed at an
inclined angle. D is a gas tube with long thread by means of which the reflectors
may be raised, lowered, or adjusted, to any area of outlet.
Fig. 2. A is a reflector open at the top, with a conical socket to which may be
fixed an iron bridge, tapped in the centre to follow the thread on gas tube D'.
B' is a reflector similar to A on Fig. 1. C' shews a gas bulb with two rings
or series of gas jets the inner circular series being so arranged that the light is
not intercepted by the outer series of jets.
Fig. 3. A is a reflector open at the top having a vertical socket to which a
bridge may be fixed for holding and adjusting the reflectors. B is a reflector
with outlet at top, the space between A* and * may be regulated to control the
area of outlet.

page_text: Fig. 4. shews a large & powerful light having a series of frustrums of cones, the
distance between can be regulated; A³ is a cone open at the top, with vertical
socket and suspension bridge.
A is a dish shaped reflector, slightly curved and open at the top, with a socket
and suspension bridge.
B³ is a saucer shaped reflector with outlet at top and means for raising and
lowering.
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 :-
1st. The arrangement of one or more reflectors placed over gas lights in such
a manner that the area of outlet for the gas products and heat may be easily
increased or diminished, and the distance from the tip of the flame to the reflector
be regulated to suit the size of flame, various qualities of gas, and the number of
jets, so as to ensure a steady light, prevent the deposition of carbon on the reflectors
and control the exhaust when used for ventilating lights.
2nd. That by arranging the reflectors in a series of one or more as described,
the tendency of the enamel to chip off is avoided and the illuminating power
of the light also dimensions of the reflectors may be increased to any extent
desirable.
Dated this 19th day of August 1891.
