Improvements in Gas Lamps.
I, ADAM WIGHTMAN CLARK, of Victoria Works, Buchan Street, Glasgow, in the
County of Lanark, North Britain, Brassfounder, do hereby declare the nature of this
Invention to be as follows, that is to say :-
My said Invention relates to gas lamps of the kind described in my Patent Speci-
fication No. 15201 of 1885, and is applicable to all gas lamps in which an annular
flame or an annular series of flame jets is projected horizontally or with some upward
or downward inclination beneath an annular reflector or beneath parts arranged for
heating the gas or the air and the object of my Invention is to render the parts
above or near the flame or heated by it more,durable than as hitherto made.
In carrying out my Invention I make the reflector or part immediately above or
within the flame to consist principally of asbestos; and for this purpose 1 take asbestos
pulp and having mixed with it a little clay or other suitable substance to give it
adhesion I mould it so as to form an annular plate of suitable size and form. After
being moulded the annular plate of asbestos is carefully dried and may then he fixed
in position in the lamp. The asbestos plate or ring becomes intensely heated by the
flame and insures the thorough combustion of the gas.

page_text: I, ADAM WIGHTMAN CLARK, of Victoria Works, Buchan Street, Glasgow, in the
County of Lanark, North Britain, Brassfounder, 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, that is
to say :-
My said Invention relates to gas lamps of the kind described in my Patent Specifi
cation No. 15201 of 1885, and is applicable to all gas lamps in which an annular
flame or an annular series of flame jets is projected horizontally or with some upward
or downward inclination beneath an annular reflector or beneath parts arranged for
heating the gas or the air; and the object of my Invention is to render the parts
above or near the flame or heated by it more durable than as hitherto made.
In carrying out my Invention I make the reflector or part immediately above or
within the flame to consist principally of asbestos; and for this purpose I take asbestos
pulp and having mixed with it a little clay or other suitable substance to give it
adhesion I mould it so as to form an annular plate of suitable size and form; or the
asbestos may be taken in the form of millboard as manufactured for non-conducting
coverings and other purposes and after being moistened with a solution or liquid con-
taining a suitable adhesive substance may be moulded into the desired form. After
being moulded the annular plate of asbestos is carefully dried and may then be fixed in
position in the lamp. The asbestos plate or ring becomes intensely heated by the flame
and insures the thorough combustion of the gas.
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 :-
Making the reflectors or other parts of gas lamps subjected to the heat of the flame
or flames, of asbestos substantially as hereinbefore described.
