Improvements in Burners for Hydrocarbon and other Volatile
Oil Lamps.
We, JOHN CHARLES CRAMPIN READ, of Clent Villa, Serpentine Road, Harborne,
in the County of Stafford, Manager of Works, and GEORGE FREDERICK AUGUSTUS
GRIFFIN, of Mansfield, in the County of Nottingham, Draughtsman, do hereby declare
the nature of this invention to be as follows:-
The object of our improvements is to facilitate the lighting and trimming of Lamps,
by an arrangement which secures the greatest safety in lamps combined with facility
and expedition in lighting and trimming.
Our invention consists of an improvement or improvements upon a burner
introduced into this country from America about twenty three years ago; in which
the upper part of the burner was raised by means of three helical slots, working upon
three studs fixed in the body of the burner, which was of tubular shape.
To carry our improvements into effect we take two rings of different sizes, the
larger to fit within the upper, and the smaller to fit within the lower part of the
perforated body of the burner; and we secure these rings together at a proper distance
from each other, by two or three, or more arms or stays. To and upon the upper
edge of the said lower ring we construct, in opposite positions, two pairs of inclined
arms; each pair being joined together at the top by a bar of metal of like strength,
and curved as if formed from a tube being a continuation of the said smaller ring; and
to which we fix two projecting studs for the purpose hereafter described. The upper
and larger ring is principally for a support and connection with the body of the
burner. To the inner edge or rim of a flat ring or bracket, which we attach to the
under side of the gallery of the burner, we construct, in opposite positions projecting
downwards, two inclined plates or arms, in each of which we make two inclined or
belical slots, each slot having a lateral recess at the bottom. These two slotted plates
or arms fit and work on the outside of the said perforated plates or arms on the lower
ring first described, and the slots work up and down upon the studs carried thereon.

page_text: In its ordinary position the flat ring or bracket and gallery rests upon the top of
the upper ring of the pair of rings first described, which rises flush with the upper
part of the perforated body of the burner within which they are placed and secured.
To the under part of the flat ring or bracket, we fix a handle for raising and lowering
the gallery, cone and chimney holder. When it is desired to trin or light the lamp,
the handle is pulled round towards the left--the gallery turning with it, and by means
of the helical slots working up and down on the studs, the gallery, globe and chimney are
raised above the tops of the wick tubes, and maintained in that position by the lateral
recesses at the bottom of the slots engaging the said studs; so that the wicks may be
trimmed and lighted without removing the globe and chimney.
But in this as in all other arrangements there can be but little room allowed for
trimming, which can be done but imperfectly and with special scissors. We provide
to meet this difficulty by hinging the gallery and cone to the flat ring or bracket
hereinbefore described, so that when the globe is removed it may be lifted up at right
angles to its normal position, freely exposing the wick tubes, and giving full liberty
for trimming the wicks level with the tops of the said wick tubes. The gallery and
ring or bracket is secured in position after trimming by a catch...
By our arrangement for raising the gallery &c., we dispense with the guide rods as
used by others; and by removing these conductors of heat between the flame and oil,
the oil in the vessel is kept at a lower temperature than when guide rods are employed,
thus lessening the production and escape of gas or vapour, and rendering lamps thus
constructed more free from smell, and less liable to explosion.

Improvements in Burners for Hydrocarbon and other Volatile
Oil Lamps.
We JOHN CHARLES CRAMPIN READ, of Clent Villa, Serpentine Road, Harborne,
in the County of Stafford, Manager of Works, and GEORGE FREDERICK AUGUSTUS
GRIFFIN, of Mansfield, in the County of Nottingham, Draughtsman, 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 our Improvements is to facilitate the lighting and trimming of Lamps
by an arrangement which secures the greatest safety in lamps combined with facility
and expedition in lighting and trimming.
Our Invention consists of an improvement or improvements upon a burner
introduced into this country from America about twenty three years ago, in which
the upper part of the burner was raised by means of three helical slots, working upon
three studs fixed in the body of the burner, which was of tubular shape.
To carry our improvements into effect we take two rings of different sizes, the
larger to fit within the upper, and the smaller to fit within the lower part of the
perforated body of the burner; and we secure these rings together at a proper distance
from each other by two, or three, or more arms or stays. To and upon the upper
edge of the said lower ring we construct, in opposite positions, two pairs of inclined
arms, each pair being joined together at the top by a bar of metal of like strength, and
curved as if formed from a tube being a continuation of the said smaller ring, and to
which we fix two projecting studs for the purpose hereinafter described. The upper
and larger ring is principally for support and connection with the body of the burner.
To the inner edge or rim of a flat ring or bracket, which we attach to the under side
of the gallery of the burner, we construct in opposite positions projecting downwards,
two inclined plates or arms, in each of which we make two inclined or helical slots,
each slot having a lateral recess at the bottom. These two slotted plates or arms fit,
and work on the outside of the said perforated plates or arms on the lower ring first
described; and the slots work up and down upon the studs carried thereon.
In its ordinary position the flat ring or bracket, and gallery rest upon the top of the
upper ring of the pair of rings first described, which rises flush with the upper part of
the perforated body of the burner, within which they are placed and secured. To the
under part of the flat ring or bracket we fix a handle for raising and lowering the
gallery, cone, and chimney holder. When it is desired to trim or light the lamp the
handle is pulled round towards the left-the gallery turning with it and by means of
the helical slots working up and down on the studs, the gallery, globe, and chimney
are raised above the tops of the wick-tubes, and maintained in that position by the
lateral recesses at the bottom of the slots engaging the said studs; so that the wicks
may be trimmed and lighted without removing the globe and chimney.

page_text: But in this as in all other arrangements there there can be but little room allowed
for trimming, which can be done but imperfectly and with special scissors. We
provide to meet this difficulty by hinging the gallery and cone to the flat ring or
bracket hereinbefore described, so that when the globe is removed it may be lifted up
at right angles to its normal position, freely exposing the wick tubes, and giving full
liberty for trimming the wicks level with the tops of the said wick-tubes. The gallery
and ring or bracket is secured in position after trimming by a catch.
By our arrangement for raising the gallery &c., we dispense with the guide-rods as
used by others, and by removing these conductors of heat between the flame and oil,
the oil in the vessel is kept at a lower temperature than when guide rods are
employed; thus lessening the production and escape of gas or vapour, and rendering
lamps thus constructed more free from smell, and less liable to explosion.
In order that our Invention may be better understood we will describe the same
aided by the accompanying drawings.
Fig. 1 represents a Lamp burner with the gallery and appurtenances raised and
supported by our arrangement for effecting that purpose, Fig. 2 illustrates separately
the mechanism by which the gallery &c., are raised and sustained; and Fig. 3 is a
top view of the same shewing the gallery hinged thereto.
a, a, Figs. 2 and 3 are the rings, the lower of which is for carrying the inclined guide-
arms b, b, and to support the mechanism on the bottom of the perforated body of the
burner, and the upper to fit within the rim of the said perforated body of the burner
to steady the mechanism, which is secured therein by the stud c, and thumb screw d.
The said rings are connected by the stays e, e. f, is the flat ring or bracket, to which
is attached the inclined slotted plates or sections of a tube J, which engage and work
over or around the lower arms, and are made to rise with the gallery &c., by the
inclined slots working up and down on the studs g, g. At the bottom of the said slots
we form lateral recesses, which by a slight continuation of the rotary motion of rising
engages the studs g, g, and thus sustains the upper part of the burner in a raised
position whilst necessary. It will be seen that the rotary motion is communicated by
the handle h, which is turned to the left in raising, and to the right in lowering the
gallery, cone &c.
Fig. 3 shews the manner in which we hinge the gallery to the before mentioned
flat ring or bracket of the raising arrangement, to give more free access, when required,
to the wicks for trimming or cleaning. By this means the gallery can be raised to a
right angle to its normal position-thus giving full access to the wicks, wick-tubes, and
the inside of the body of the burner.
This part of our Invention can be applied to burners having other means of raising
the upper portion of the burner, or where guide-rods only are used.
Having now described the nature and object of our Invention, and the manner of
carrying the same into effect, we declare that what we claim and desire to protect by
Letters Patent is―
The arrangement for raising the gallery, cone, chimney and globe for lighting and
trimming; and also the hinging of the gallery to the top or otherwise of the said or
other raising arrangement to give free access (for trimming and cleaning) to the
wicks and inside of the burners of hydrocarbon and other oil lamps, as herein described
and illustrated by the drawings.
