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 consists of an apparatus which may be fixed to any ordinary fire-
grate, fireplace, heating, stove, boiler fire or any place where a fire is required to be
kindled and is constructed to burn gas, either ordinary coal gas, or gas specially
made from oil, spirits or other material.
A piece of tube (a) Fig. No. 1 forms the body of the apparatus to which is attached
a bulb (e, e) for the purpose of mixing the atmospheric air with the gas, which comes
into it through the sinall aperture in (f) the apparatus is fixed to the bars of the
grate (b, b) by means of a cross piece (c, c) fitted to the end of the tube, which,
by giving half a turn goes against the inner side of the bars and is kept in place
by an outside collar (k, k,) against which is a spiral spring (d) with a piece
reaching to the arm of the stop cock (9,) which, on the apparatus being released from
the bars, shuts off the gas automatically.
A piece of piping is attached to (s,) to convey the gas to the apparatus which when
lighted emits a flame from the mouth of the apparatus at (a) and lights the coal or
coke or other combustible direct.
Fig. No. 2, shows the apparatus with three burners or tubes attached with one
bulb (x), a joint being fitted at (t,) for the purpose of fixing the apparatus, adjusting
the apparatus to any requisite angle and for folding the apparatus back when .not in.
use and is also made so that the apparatus may be removed if desired, a permanent
pipe being fitted to the grate for the purpose of conveying the gas.
This apparatus (Fig. No. 2) is also made portable, by the joint being so con-
structed, that when it is removed, the stop cock is automatically closed and the gas
shut off.
The bars of the grate themselves may be utilised, where so constructed to serve
tubes for conveying or burning the gas with an adaptation of the same
arrangements.
as
Although a bulb has been shown, any other form of gas burner may be used
although the bunsen burner is preferred. In case of apparatuses! for lighting loco-
motive or other fires of a large nature, a blast is used with good effect for forcing the
air into the gas, and thus giving a hotter flame, this can be done also with those above-
described by the addition of an extra tube, attached to the bulb.

page_text: 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,
First. The form of apparatus consisting of one or more tubes with or without one
or more bulbs, bunsen argand or other burners as herein described or shown.
Second. An apparatus having attachments fitted to form a means of fixing to the
bars of an ordinary grate all as herein described or shown.
Third. An apparatus having a spring action for fixing to grate with collar and end
piece, all as herein described or shown.
