I HENRY FOURNESS of the firm of H. Fourness and Company of Pritchard Street
Charles Street Manchester in the County of Lancaster Gas Lamp Manufacturers do
hereby declare the nature of this Invention to be as follows:-
My said Invention relates to means for lighting regenerative gas lamps in which
the light is enclosed in a glass shield similar for example to the lamps manufactured
by my firm and now well known in the market as The Fourness Regenerative Gas
Lamps. My invention is however applicable to other types of lamps of a similar
nature and having an enclosed light. In these classes of lamps the lighting has been
effected by providing a removable or sliding door or trap at the foot of the glass
shield or by forming an aperture in the side of the shield or by making the shield
capable of being removed or slid downward and in some instances by swinging a
master light toward the burner of the lamp. All of these methods are however
comparatively inconvenient. By the means constituting my invention I am enabled
to ignite and shoot a tongue of flame into the interior of the shield and toward the
burner so that when the gas is turned on the lamp is immediately lit without
disturbing the shield and without providing any ports or openings therein for the
introduction of tapers or lighting media. In applying my invention to a pendant for
example where the gas is controlled by a cock on the supply pipe I lead a small byc-
pass tube from above the controlling cock to a small gas tap fixed at the side of the
lamp and above the shield. The bye-pass tube which has thus a constant supply of
gas is led to one side of the tap and from the other side a tube points directly through
a perforation in the side of the upper part of the lamp so as to shoot a flame into the
interior of the shield and toward the burner in the lamp; but where it is inconvenient
to make this direct communication I lead a branch upward from this latter tube and
curve it downward in the direction of the flame the inner delivery end coming
'מ

page_text: opposite to the aforesaid horizontal tongue of flame and being lit thereby. The
tongue of flame from the said curved branch is thus projected downward toward the
burner so that when the gas supply cock is turned on, the lamp is immediately lit.
Where the gas supply of a pendant lamp is controlled by a tap at the foot of the
lamp the bye-pass tube is led from a point directly opposite to the lighting gas tap.
In cases where the lamp is supported on a bracket or standard and supplied with gas
from beneath the said lighting gas tap could be fixed beneath so as to project the
tongue of flame upward toward the burner.

Improvements in Means for Lighting Regenerative Gas Lamps.
I HENRY FOURNESS of the firm of H. Fourness and Company of Pritchard Street
Charles Street, Manchester in the County of Lancaster, Gas Lamp Manufacturers do
hereby declare the nature of this Invention and in what manner the same is to be
performed to bo particularly described and ascertained in and by the following
Statement and accompanying drawings :-
My said Invention relates to means for lighting regenerativo gas lamps in which
the light is enclosed in a glass shield similar for example to the lamps manufactured
by my firm and now well known in the market as The Fourness Regenerative Gas
Lamps. My Invention is however applicable to other types of lamps of a similar
nature and having an enclosed light. In these classes of lamps the lighting has been
effected by providing a removable or sliding door or trap at the foot of the glass
shield or by forming an aperture in the side of the shield or by making the shield
capable of being removed or slid downward and in some instances by swinging a
master light toward the burner of the lamp. All of these methods are however
comparatively inconvenient. By the means constituting my invention I am enabled
to ignite and shoot a tongue of flame into the interior of the shield and toward the
burner so that when the gas is turned on the lamp is immediately lit without
disturbing the shield and without providing any ports or openings therein for the
introduction of tapers or lighting media.
And in order that my said invention may be properly understood I will now
proceed more particularly to describe the same with reference to the annexed sheet
of drawings.
Fig. 1 of the said drawings is a sectional view of a pendant lamp of the con-
struction now well known as the Fourness regenerative gas lamp. The supply of gas
to the burner a is controlled by a valve & operated from beneath the lamp. The supply
of gas to the lighting apparatus is taken from the gas supply pipe c at the point
marked z. At this point I interpose a tee piece d and branch e by which a constant
supply of gas is led to the tap f. The tap has two outlets, one at the point g, and
one at the point the latter being directed downward toward the interior of the
lamp. When the tap is turned on, gas issues from both of these outlets. Just
opposite to the outlet g I form an opening in the surrounding shield i of the lamp
and immediately opposite to the outlet I form another opening in the upper part of
the lamp. When the lamp is to be lit I turn on the tap fand ignite the gas issuing
from g. This flame strikes and ignites the gas issuing from and the flame from his
shot downward into the interior of the glass shield k. I then turn the valve 6 and
allow gas to issue from the burner a. This issuing gas is immediately ignited by the
flame from and the lamp is lit. The tap is then turned off until again required.
It will bo evident that instead of the two outlets g and to the tap one such outlet
might in certain circumstances perform the required duty. In the arrrangement
shown the double outlets are preferable. In the case of a lamp supported from

page_text: beneath on a bracket or standard and supplied with gas from beneath, the lighting
tap could be fixed beneath so as to project a tongue of flame upward toward the
burner. Fig. 2 of the drawings shows a pendant lamp in which the supply of gas
to the burner is governed by a tap on the gas supply pipe c. In order to render
the lighting tap altogether independent of control by this tap 1 and to ensure the
requisite constant supply of gas to the tap f I prolong the branche and carry it
upward and unite it to the supply pipe c at a point above the gas tap 7. There will
thus always be a supply of gas to the tap whether the tap is turned on or off.
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 :-
--
The improved means for lighting gas lamps the burner of which is enclosed in a
glass shield the said means consisting of an auxiliary tap adapted to project a pencil
of flame into the interior of the glass shield and toward the burner so as to light the
lamp, substantially as hereinbefore described and shown or any mere modification
thereof.
