Year: 1884

page_text: I ISAAC BLAKE of 3 St George's Crescent Birmingham in the County of
Warwick Lamp Manufacturer do hereby declare the nature of my Invention for
CERTAIN IMPROVEMENTS IN LAMPS FOR BURNING GAS AND VOLATILE OILS to
be as follows:-
My improvements relate to the Construction of Burners in part and part to their
attachments the object being to increase the illuminating power of the light and to
spread its rays over a greater space than is done by the ordinary lamps.
I will describe my invention thus First I make a gas box with connections to
fit the gas pipe and in this gas box I fit one or more tubes having suitable burners
in them, I also make a ring to fix on the gas box with set screens and I attach to
the Ring two or more upright supports or I dispenso with the ring and fasten the
supports to the gas box I attach a glass holder to the top of the supports and to the
glass holder I fix a perforated metal disc or other form of perforated metal having
holes in for the tubes with burners to pass through and on the glass holder I place
a cylindrical dioptric or other lens so that its centre and the centre of the flames
may be in or nearly in the same horizontal plane 1 make a metal ring to fit the
top of the lens, the ring to have some projections inside about midway between the
upper and lower edges, the said projections to rest upon the top of the lens and
support the ring, I also make a conical or straight glass chimney with a flange at
the base to fit into the ring and rest upon the projections; the chimney being
secured in its position by Screws working in the ring. The perforated disc will
regulate the supply of air to the flames, keep them steady and increase their
brightness; and the lens will concentrate the light and then disperse it over a
greater space than is done by ordinary Lamps.
Second When used for burning volatile oils I only require the following parts
viz the lens, the ring at the top of the lens and the glass chimney above the ring-
The bottom of the lens, in this case, is fitted into a glass holder which is attached
to a suitable burner for consuming volatile oils.

I ISAAC BLAKE, of 3 St. Georges Crescent, Birmingham, in the County of
Warwick, Lamp Manufacturer, do hereby declare the nature of my said Invention
for "CERTAIN IMPROVEMENTS IN LAMPS FOR BURNING GAS AND VOLATILE OILS
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
My improvements relate to the construction of Burners in part, and part to their
attachments, the object being to increase the illuminating power of the light and to
spread its rays over a greater space than is done by the ordinary lamps.
I will describe my Invention thus -First. I make a gas box with connections to
fit the gas pipe, and in this gas box I fit one or more tubes having suitable burners
in them, I dispense with the ring and fasten the supports to the gas box, I atlach
a glass holder to the top of the supports and to the glass holder I fix a perforated
metal disc or other formn of perforated metal having holes in for the tubes with
burners to pass through, and on the glass holder I place a cylindrical dioptric or
other lens so that its centre and the centre of the flames may be in or nearly in
the same horizontal plane, I also make a conical or straight glass chimney with
a flange at the base to fit into the ring and rest upon the projections. The
perforated disc will regulate the supply of air to the flames, keep them steady and
increase their brightness; and the lens will concentrate the light and then disperse
it over a greater space than is done by ordinary lamps.
Second. When used for burning volatile oils, I only require the following parts
viz the lens, the ring at the top of the lens, and the glass chimney above the ring.
The bottom of the lens, in this case is fitted into a glass bolder which is attached
to a suitable burner for consuming volatile oils.
And in order that this my said Invention may be more clearly understood I will
now proceed to describe the same reference being made to the sheets of drawings,
to the various figures and letters marked thereon that is to say.
No 1 SHEET OF DRAWINGS.
Fig. 1 is a view half elevation and half sectional of argand gas burner, with
dioptric glass or lens, and outer or special glass chimney.
Fig. 2 is a view half elevation and half sectional of a duplex gas burner with
dioptric glass or lens, and outer or special glass chimney.
Fig. 3 is a view half elevation and half sectional of a duplex burner for mineral
or volatile oils, with dioptric glass or lens, and outer or special glass chimney.

No 2 SHEET OF DRAWINGS.
Fig. 4 is a view half elevation and half sectional of a single gas burner with
dioptric glass or lens, and outer or special glass chimney.
Fig. 5 is a view half elevation and half sectional as Fig. 1 with dioptric glass or
lens the outer or special glass chimney being substituted by the straight chimney.
Fig. 6, 7, 8, 9, 10 parts detached.
No 3 SHEET OF DRAWINGS.
Fig. 11 is a view half elevation and half sectional through dioptric glass or lens,
and outer or special chimney to argand gas burner, differing in their shape or
configuration to the preceding.
Fig 12 is a view half elevation and half sectional through dioptric glass or lens
and outer or special glass chimney to duplex burner for mineral or volatile oils in

page_text: In Figs. 1, 2, 4, 5, 11, A is the gas box and A¹ the interior or secreted gas
box; B, the connecting piece screwed interiorally at B1, for fitting to the gas
pipe, C is the tube or tubes which receive the jets or burners D; E; is the holder
for receiving the dioptric glass or lens F-G, is a doomed form being part of or
connected to E having apertures corresponding to the formation of flame emitted
from the burner; H is a perforated metal dise, or its equivalent; gauze wire may
be employed being arranged interiorally. I is also a perforated metal plate
arranged exteriorally, the tubes C, with jets or burners, D for gas passing through
both these at I, J, is the outer glass chimney, J¹, the inner glass chimney as
hitherto employed.
In Figs 1, 2, 4, 11 the dioptric glass or lens F, is shewn as applicable to gas
and for out of door use with outer glass chimney in application, my ain and object
being by the combination of parts, the position of the flame and lens F to increase
the quantity of light, and to project from an horizontal point the same over a wide
extent of surface, so that the illumination instead of being limited to the direct
light is increased and diffused to the greatest possible extent.
In Fig. 5 the lens F is shewn and the outer glass chimney J, being substituted
by the old chimney J', as may be required in some cases.
In Figs. 11, and 12, the first named, constructed with an argand gas burner D,
the other with burner for mineral or volatile oils, and both for out door or domestic
use, both fitted with dioptric glass or lens F, and outer glass chimney J; a
departure is here made in the shape or configuration only, the object being to
direct or deflect the rays of light in a more equable manner than has been done
by means of deflectors or shades previously employed, and with as small an amount
of shadow from the glass holder E as possible.
The burners for gas having a flat flame or flames and constructed as before set
forth may be used effectively for some purposes without the dioptric glass or lens F,
and outer glass chimney J.
The parts unlettered have no bearing hereon.
The above being my said Invention I wish to say that I do not confine myself
to the preciso details or arrangement of parts as shown on the accompanying sheets
of drawings, but that I hold myself at liberty to alter or modify the same without
departing essentially from my said Invention-Neither do I claim the construction
of the several parts as herein before specified, taken seperately and apart from cach
other.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is
1 To the burners of gas either argand, bat wing, fishtail, or other burners,
having one, two, or more flames, the construction of outer glass chimney in
application to the dioptric lens, and in combination or arrangement with other
parts, for out door, or in door lighting purposes substantially as herein before set
forth and described.
2 The application of the said outer glass chimney only, to the dioptric lens of
lamps for burning mineral or volatile oils either for one two or more flames, for
out door and in door, or domestic purposes, substantially as set forth and described.
3rd The construction combination or arrangement of parts, formning burners
applicable for gas having flat flames for out door, in door, or doinestic purposes and
without the application of the outer glass chimney and dioptric lens substantially
as set forth and described.
Dated 9th October 1884.
