I, PRUST SYMONS, of 11 Union Street, Swansea, in the County of Glamorgau,
Sanitary Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to means whereby the mantles of incandescent gas
burners can be firmly and steadily clasped and held in position close to the flame
so as to ensure full incandescence to the bottom of the mantle.
According to my invention the mantle is held between a cylindrical ferrule aud
expanding cylindrical segments or tongues fitted on the exterior of the ferrule and
closed or shut together around the ferrule, so as to clip the mantle thereto, by
means of a band or ring which is adjusted as desired by means of a lever, clip,
spring or other suitable device.

Improvements in Means for Holding or Supporting the Mantles
of Incandescent Gas Burners.
I, PRUST SYMONS, of 11 Union Street, Swansea, in the County of Glamorgan,
Sanitary 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 means whereby the mantles of incandescent gas burners
can be firmly and steadily clasped and held in position close to the flame so as to
ensure full incandescence to the bottom of the mantle.
According to my invention the mantle is held between a cylindrical ferrule and
expanding cylindrical segments or tongues fitted on the exterior of the ferrule and
closed or shut together around the ferrule, so as to clip the mantle thereto, by
means of a band or ring which is adjusted as desired by means of a lever, clip,
spring or other suitable device.
In the accompanying drawings Fig. 1 is an elevation showing my invention with
an incandescent mantle fitted therein; Fig. 2 is another elevation of the holder
alone taken at a different angle, and Fig. 3 is a plan of Fig. 2.
A is the ferrule, which in the example shown in the drawings is slotted at its
upper end and bent inwards cone shape as shown at a so that the ferrule is of a
concavo-cylindrical shape, but it may be made cylindrical throughout. BB are spring
arms outside the ferrule A rigidly secured at their lower ends to the bottom part

page_text: of the ferrule A and carrying at their upper ends cylindrical segments or
tongues bbwhich, when closed or shut together form a ring or cylinder. Instead
of being strips as shown in the drawings, the arms B may each be cylindrical
segments. C is a ring or band surrounding the spring arms B and serving to close
together the cylindrical segments or tongues bb when said ring C is raised, and cis
an arm formed on or secured to the ring C by means of which the latter may be
raised or lowered as required. A lever, clip, spring, or other suitable device may
be connected to the arm c or to the ring C for the purpose of holding the latter in
the raised position shown in Fig. 1.
To secure the mantle its lower end is passed over the upper end a a of the
ferrule A so that it then lies with the convex surface of the ferrule on its inside
and the concave surfaces of the cylindrical segments or tongues 6b on its outside.
It is secured in this position by raising the outer band or ring C, which is held up
by any suitable device as before described.
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 ;-
1. For holding the mantles of incandescent gas burners, a clip device consisting
of an inner ferrule, expanding cylindrical segments or tongues secured to or formed
on the outside lower part of the ferrule, and an outer ring surrounding the
cylindrical segments and serving when adjusted to close same on to the ferrule,
substantially as described and illustrated in the accompanying drawings.
2. A clip device for holding the mantles of incandescent gas burners consisting
of a ferrule, spring clips surrounding the ferrule and a ring or band for closing the
springs on to the ferrule substantially as described.
