page_text: I, HARRY TEE, of 50, Castle Street, Liverpool, in the County of Lancaster,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention has reference to gas lamps, and more especially to those
employing incandescent mantles or similar material or devices, used for street
lighting and analogous purposes.
According to this invention, there is combined with the main burner, on which
the mantle or similar device is used, an igniting device by which this type of
burner is readily ignited, and without liability of fracture or damage to the
mantle or light-giving medium. This device consists of a pipe leading from the
main gas supply pipe, and above the main tap thereon; and having upon it a
tap, and a weighted lever or arm, disposed within the lamp, and adapted to be
operated by a flap in the bottom, or forming a substantial portion of the bottom,
and hinged next the gas pipe, so that it moves towards the gas pipe and tap. And
it is so arranged that this flap presses the pilot light tap lever or arm upwards,
in the act of the lamp being lit; this act being effected by pressing the flap up
by a lighting torch or device, and passing it up into the lamp, when it sets
light to gas jets issuing from holes in the side of the pilot tube.
gas
These holes in the side of the tube extend upwards from a point which can be
easily reached by the ignition torch, to a point contiguous to the main burner;
so that the flame burning at the lower hole will set light to the gas issuing from
that above; and so the kindling operation will travel up to the point referred to.
The main gas tap of the lamp will be outside it, and in lighting the lamp, it
will have to be opened prior to passing the torch up into the lamp, and operat-
ing the flap, and the pilot light tap lever.
The cases of the lamps will be of types such as are commonly used in street
lamps, ware-house and other similar lamps, or the like.

According to this invention, there is combined with the main burner, on which
the mantle or similar device is used, an igniting device by which this type of
burner is readily ignited, and without liability of fracture or damage to the
mantle or light-giving medium. This device consists of a pipe leading from the
main gas supply pipe, and above the main tap thereon; and having upon it a
tap, and a weighted lever or arm, disposed within the lamp, and adapted to be
operated by a flap in the bottom, or forming a substantial portion of the bottom,
and hinged next the gas pipe, so that it moves towards the gas pipe and tap. And
it is so arranged that this flap presses the pilot light tap lever or arm upwards,
in the act of the lamp being lit; this act being effected by pressing the flap up
by a lighting torch or device, and passing it up into the lamp, when it sets
light to gas jets issuing from holes in the side of the pilot tube.
These holes in the side of the tube extend upwards from a point which can be
easily reached by the ignition torch, to a point contiguous to the main gas burner;
so that the flame burning at the lower hole will set light to the gas issuing from
that above; and so the kindling operation will travel up to the point referred to.
The main gas tap of the lamp will be outside it, and in lighting the lamp, it
will have to be opened prior to passing the torch up into the lamp, and operat-
ing the flap, and the pilot light tap lever.
The case of the lamps will be of types such as are commonly used in street
lamps, ware-house and other similar lamps, or the like.
Drawings, in which Figure 1 is an outside elevation, and Figure 2 a trans-
verse section of the lower part of the lamp illustrating the invention, the nature
of which is above described.
"
In these drawings, a is the lamp case proper, which is of an ordinary "street"
kind; is the incandescent gas lamp or burner, of which c is its gas supply pipe;
and is the pilot light pipe, having upon it the tap e. e is the plug of this
tap, having upon it the lever, on the outer end of which is a weight f'; and
g is the door or flap in the bottom of the lamp, through which the torch to light
the lamp is passed, in the act of lighting.
The main gas supply pipe of the pipe e will be placed in a suitable position
below the bottom of the lamp, and is as shown in the drawing.
The upper end of the pilot light pipe or tube & is passed up between the burner
proper b, and the gallery 6¹, and holes are provided in it at a suitable points,
so that when the torch is passed up through the opening normally covered by
the flap g, the gas issuing out of the lower of these holes will be lit, and the
flame will be propagated upwards into the burner by the ignition of the gas jets
issuing through the small holes of the tube d.
In the act of passing the torch into the lamp a, the flap g is lifted up, and
the lever f which normally rests on the outer edge (its hinge being disposed
between the edges of the bottom) will be raised, and as the flap is further lifted
upwards, the plug e¹ of the cock e is turned, and supplies gas, by way of the
connection c¹, to the igniting tube d.
When the torch is drawn down out of the case a, the flap g follows, and so
allows the tap, lever f to fall, its return action being effected by the weight f¹;
when it reaches the position shown in Figure 2, the gas tape will be closed com-
pletely.
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 A gas lamp of the kind herein referred to, having a supplemental ignition
tube, combined with the main burner, and the main supply pipe, and having a
tap thereon with a weighted lever for opening and closing same, said lever being

page_text: operated by a flap in the bottom of the lamp; arranged and adapted to operate
substantially as set forth.
2. The lamp having parts arranged, combined, and adapted to operate parti-.
cularly as set forth with reference to and shown in the drawings.
