Improvements in or relating to Gas Lamps or Burners.
JAMES LOVE 32 Linton Road Barking in the County of Essex Gas Engineer
do hereby declare the nature of this invention to be as follows:—
This invention relates to incandescent gas lamps and burners, and has for its
objects the prolongation of the life of the mantle and the attainment of an
increased area of luminosity with incandescent lamps constructed as heretofore it
is necessary to so arrange that a considerable portion of the length of the mantle
shall dip down below the top edge of the cone or cylinder through which the gas
issues, in order to ensure that the lower edge of the mantle shall not be subjected
to such a temperature as will destroy it or cause it to curl up. For should the
mantle once begin to curl up it will continue until it is destroyed & must be
replaced by a new one.
By my invention I provide a ring of steel or other suitable material separated in
one part to form an elastic spring, this spring or metal band is placed over the
centre tube & pressed down as far as required here it holds firmly by its gripping
power, this is used for supporting a ring or collar of metal, clay, or other suitable
material, this ring or collar has an aperture in the bottom to allow it to pass over
the centre tube & rest upon the aforesaid steel ring, with the sides projecting
upwards to a distance slightly above the level of the tube I also provide a socket
pin which is inade of clay, or other suitable material, having a pin at one end and
a socket at the other, this socket pin is used for raising the short fork to the
height required. To fix the mantle lower it over the fork & let the lower end
enter the circular collar lower down until the mantle is suspended on the fork,
& in this way the initial luminosity is increased, and the lower edge of the mantle
is kept comparatively cool, by the using of the clay ring & so prevents the
mantle from getting over-heated, & curling outwards thus economising the mantles.
Another important feature of my invention is that the clay ring forms a wind-guard, as
in places where burners are exposed to draughts it forms a perfect protection between
the mantle & the centre tube & thus prevents the current of air from entering the
mantle. In the burner as now used there is a space between the mantle & centre
tube through which a draught often passes swinging the mantle backwards &
forwards & entirely destroying it, this cannot happen when my invention is applied
as the mantle is held firmly in the clay ring the space between mantle & tube is
closed by the said ring.

COMPLETE SPECIFICATION.
Improvements in or relating to Gas Lamps or Burners.
I, JAMES LOVE, of 32 Linton Road, Barking, in the County of Essex, Gas
Engineer, 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 incandescence gas burners and has for its objects the

page_text: prolongation of the life of the mantles and the attainment of an increased area of
luminosity without increasing the size of the mantle.
In burners constructed as heretofore it is necessary to arrange that a con-
siderable portion of the mantle shall dip below the top edge of the cone or
cylinder through which the gas issues in order to insure that the lower edge of the
mantle shall not be exposed to a temperature that would destroy it or cause it to
curl up. Should curling once commence it will continue until the mantle is
destroyed or rendered unfit for use.
According to my invention protect the lower end of the mantle by means of a
ring of metal or clay or other suitable material which surrounds the lower end of
the mantle and prevents it from curling up and burning out, and also steadies the,
mantle and prevents it from swinging about when the burner is exposed to draughts
of air. Moreover by reason of the protection afforded by the ring, the mantle can
be raised to expose a greater area of luminosity. For raising the mantle I provide
a socket pin to elevate the fork as hereinafter described.
Referring to the accompanying drawing,
Figure 1 is a side elevation of a burner having my improvements applied
thereto, the globe and chimney being removed.
"
Figure 2 is a vertical section of the same.
Figure 3 is a perspective view of the protecting ring detached, and
Figure 4 is a perspective view of the socket pin.
Like letters denote corresponding parts in the several figures.
A. is the burner, B is the mantle, C is the fork for supporting the mantle, and
D is the gallery for supporting the chimney. All of these parts are constructed
as heretofore or in any suitable manner. E is a ring of thin metal, clay or other.
suitable material having a plain cylindrical or slightly conical or curved part at its
upper end into which the lower end of the mantle is tucked, the ring being of such
a diameter as to receive the mantle without crushing the same. The lower part of
the ring is perforated to admit air freely around the outside of the mantle. I may
support the ring in any suitable manner, a convenient support being the gallery D.
on which the ring may be allowed to rest and in which it may be constructed to
fit. Another mode of support would be by means of a steel spring constructed to
grip the burner tube. I prefer however to use the gallery as above described for
supporting the ring.
To fix the mantle I first place the ring in position and then I lower the mantle
over the fork and pass the lower end of it into the ring and allow it to descend
until its upper end is suspended in the fork in the usual manner. The lower end
of the mantle is kept cooler by the use of the ring than would otherwise be the
case and the edge is prevented from curling and from burning out thus greatly
lengthening its life. Moreover the ring forms a wind guard which keeps the
mantle steady. As the mantles can be raised without detriment when their lower
edges are protected as above described I provide for supporting them at an,
increased elevation by means of a socket pin F. having a stem fat its lower end to
enter the hole or socket in the burner usually occupied by the fork and having a
hole or socket at its upper end to receive the fork. This socket pin is made of
any desired length and serves to raise the mantle and thus ensure a greater area of
luminosity and consequently more light from the same mantle.
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 1
claim is-
+
21. The combination, with an incandescence gas burner, of a ring such as E
for enclosing the lower edge of the mantle, substantially as, and for the purpose,
specified.
2. The combination, with the burner, of the socket pin as, and for the purpose,
specified.

page_text: 3. An incandescence gas burner fitted with the improvements herein described
with reference to the accompanying drawings, for the purpose specified.
