Improvements in or connected with Gas Burners.
I, EDMOND WALTER TYRRELL RICHMOND, of Academy Street, Warrington,
in the County of Lancaster, Engineer, do hereby declare the nature of this inven-
tion to be as follows:-
This invention has reference, mainly, to gas burners for heating purposes, such
as burners used in gas fires or stoves; and it has for its object to provide an
improvement or improvements in or connected with the lighting of such burners.
According to this invention, a burner of a gas fire is provided with a special
tap or tap arrangement, and pilot kindling burner; by which, when the gas is
turned on to the main burner, after it has been cut off to both this burner and
the pilot burner, the action of turning on the main gas supply to the burner,
also turns on, automatically, the gas supply to the pilot burner, by causing a
cam tappet or the like on or connected with the main tap plug, to actuate a
secondary small tap plug and open it, the supply of gas to which is taken from
the main tap body. Thus, when the fire or burner is lit, the pilot flame will be
lit also. Then, if the main gas supply is turned down, by more or less closing
the main tap, this closing action of the tap does not act upon the secondary
pilot tap, but leaves it full open; and, hence, should the main burner go out
accidentally, it will be automatically relighted by the pilot flame, which will remain
burning. And also, if the main gas tap be closed, and the gas cut off, say tempor-
arily, the pilot flame remains, and will, automatically, relight the main burner
upon the main tap being reopened,- and gas supplied to the fire:
As regards the use in connection with gas fire-places of duplex or compound
taps having the main characteristics of that just described, such a tap is set forth
in prior Patent Specification No. 21574 of 1894, and this invention consists chiefly
of the special improvement in gas fires or burners described, in which such a
tap is employed, or of an addition to said Patent.

As regards the use in connection with gas fire-places of duplex or compound
taps having the main characteristics of that just described. such a tap is set forth
in our prior Patent Specification No. 21574 of 1894, and this invention consists chiefly
of the special improvement connected with gas fires or burners described, in which
such a tap is employed.
In the drawing hereto annexed illustrating this invention, there is illustrated
a burner such as are used in gas fires, having in connection with it the gas supply,"
and rekindling device above described. Figures 1 and 2 are plans shewing the
gas taps in the open and closed positions respectively.
In the drawings, a represents the burner; b the gas supply pipe to the regulating
taps; c is the main supply tap for supplying the gas to the burner, and of which d
is the handle, and e the cam tappet for operating the pilot flame gas supply tap;
and is the pipe connecting the tap with the burner a. f is the pilot flame
supply controlling tap, of which a is the plug handle, and h the projecting part
operated by the cam tappet e; both the cam e and the part h being on the handles
or plugs of the taps c and f respectively. i is the pilot flame burner, and' the
pipe connecting it with the tap f. The burner i may be so disposed as to direct
a needle jet of gas towards one of the nozzles a¹ of the burner a.

The position of the taps, when the gas is turned off and the gas burner is
out," is shewn in Figure 2, with the two handles d and a across the duplex tap
Then when the gas is turned on, the handle b is turned to be in line with the.
direction of length of the tap, as in Figure 1; and in this movement, the corner el
of the cam tappet e will press upon the projecting part of the tap f,
and will
have moved the handle and plug of this tap to a position parallel with b. and
opened it, and when this is done, the fire may be lighted as usual, and both the
burner a and the burner i will be kindled. Now, assuming it is desired to turn
the gas down, rather low say, the handle d is turned back, more or less; but
this turning back, while it will have moved the cam tappet el, it-the cam―will
not have acted upon the projecting part hor handle g of the tap f: but will leave
it in the position to which it had been' originally moved; with the result, that
while the gas flame of the burner a has been reduced, the pilot needle flame jet
burning at the burner i. will remain of the full strength. Then, should the
burner a, under this condition, go out, through draught, or any other cause. the
pilot flame directed towards the nozzles a¹ of a will rekindle the gas coming from
them, and so relight the fire.
Of course, when the tap c is closed, and the burner a intentionally put, out, the

page_text: tap f may be closed by hand, by turning the handle f of the plug round as shewn
in Figure 2, which may then be done, as there is no portion of the tappet came of
the valve c in the way of the part h.
Of course it will be understood the invention is not restricted to the particular
form of burner or parts shewn.
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 herein described improvement connected with gas fire burners consisting
in effecting the automatic rekindling of the gas, when it has become accidentally
extinguished, by means of a double tap, and a rekindling burner, said tap or taps
being so disposed as to supply gas to the main burner and to the kindling
burner, and SO that in and by the turning of the main supply tap,
the supply to the kindling burner and jet is automatically simultaneously made;
substantially as and for the purposes set forth.
2. In a gas fire, the combination of an atmospheric gas burner a, a pilot kindling
burner f, and a double tap cf, one controlling the gas supply to said burner, and
to other to a kindling burner, said latter burner being operated and controlled by
the action of the main tap; as set forth and shewn.
