I, GEORGE BROGDEN, of 18, Croft Terrace, South Shields, General Merchant,
do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved method of supporting incandescent
mantles.
In carrying out this invention a rod or post of steatite is employed. The
upper end of this post is diminished forming a shoulder and leaving a small
projecting portion or peg on the top.
A small perforated disc of heat-resisting material such as steatite platinum
asbestos or other suitable material is placed on the top of the post, the peg
passing through the centre perforation of the disc so that the latter rests on the
shoulder of the post. The disc aforesaid is cup-shaped so as to adapt itself to
the form of the mantle. The mantle is placed in the usual way and rests on the
disc instead of hanging by a little loop as is now the usual mode of attachment.
The improved method holds the mantle steady, and it does not swing about,
thus causing it to give a better light and to be more lasting. A variation in
this invention is effected by forming on the inner surface of the cup-disc above
described a projecting socket, and this latter disc is capable of being placed on
the end of the post when by any accident the peg termination before mentioned
has been broken off, or has been omitted by design.

Improvements in incanuts
1, GEORGE BROGDEN, of 18, Croft Terrace, South Shields, in the County of
Durham, General Merchant, 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 incandescent mantle supports and has for its object
to provide an improved and more efficient method of and a means for supporting
the mantles.
According to my invention instead of suspending the mantle by a small loop
as is the usual mode I provide the mantle supporting rod or post at its upper
end with a perforated disc of convex or other suitable form upon which disc
the mantle rests and is evenly and steadily supported.

page_text: I will describe the invention in reference to the accompanying drawings in
which the figures are somewhat enlarged. Fig. 1 is an elevation of an incan-
descent burner B with mantle and support in position. Fig. 2 is a view of the
support and Figs. 3 and 3ª are respectively separate views of mantle support
and the supporting disc and Figs. 4 and 5 and 5* are similar views to Figs. 2, 3
and 3 of a modified form of the invention.
R is a rod or post of steatite or other suitable heat resisting material the upper
end of which is reduced forming a shoulder, or equivalently the latter may be
an enlargement upon the post as at r a small projecting portion or peg 1 being
left at the top (see more particularly Fig. 3). A small disc T (see Fig. 3) of
platinum, asbestos, fireclay, steatite or similar material to the post, and having
perforations arranged as at t or otherwise suitably is placed upon the top of the
post R, the peg r passing through a central perforation or hole t¹ so that the
disc rests upon the shoulder r. The disc is of inverted cup shape form or has a
convex upper surface adapted to the form of the mantle which may be of the
usual form as shown at M or specially formed to suit the form of the disc T.
The mantle M is placed upon the support in the usual way but rests upon the
disc T and is supported thereby around the whole of its top circumference, by
which, steadiness of the mantle is ensured, whilst, where the disc is separate
from the rod it has a slight movement thereon which absorbs a large portion of
the vibration before it reaches the mantle so that both the life and light giving
properties of the latter are preserved.
A variation or modification of this invention is shown in Figs. 4, 5 and 5^
wherein the inner or under surface of the disc T is provided with a pro-
jecting or it may be as shown, a recessed socket (see Fig. 5), said socket t
being adapted to receive the end of the post R' (Fig. 5) and it will be seen that,
no shoulder being required upon the post the disc T may be placed upon the end
of the post R should it become broken off, or shortened by design when the
lower edge of the mantle becomes worn or frayed.
It will be obvious that without departing from the nature of this invention
I may form the post and disc in one piece.
Having now particularly described and ascertained the nature of this inven
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
1. The improvements in incandescent mantle supports consisting in supporting
the mantle on a disc of suitable form carried by a rod or post substantially in the
manner and for the purposes set forth.
2. A support for incandescent mantles consisting in the combination with a
central rod or post R with shoulder r and peg of a perforated disc such as T
of inverted cup shape or convex form substantially as described in reference to
Figs 1, 2, 3 and 3^.
3. A support for incandescent mantles consisting in the combination with a
central rod or post of a perforated disc such as T with recessed or projecting
socket 2 substantially as described in reference to Figs. 4, 5 and 5ª.
4. The improved method and means hereindescribed for supporting incandescent
mantles.
