PROVISIONAL SPECIFICATION.
Improvements in Hand Lamps for Igniting Gas.
1 SAMUEL RILEY, of 28 Carlton Street, Leicester, Ironmonger, do thereby
declare the nature of this invention to be as follows:-
When entering, during-darkness, a factory, mill, or other building in, which are
fixed the usual gas fittings, a danger arises toithe individual if her attempt to move
about without a light, and to the contents of the building if a naked light-be.carried
with which-to-ignite each gas jet.
=
Now the object of my invention is to obviate these dangers, the first of which is
met-by using a-hand lamp for oil, having the flame venclosed on all sides; fitted
with either a plainsglass or convex lens at the front of the flame. On one vertical
side of the lamp-and connected to the same I arrange a smallhood of conical or
semi-conical shape in a vertical position, the upper end of theihood terminating in
a small tube projecting through to the inside of the lamp in a horizontal direction
towards the upper part of the lamp flame, but not touching the same.
To ignite a gas jet with my improved lamp, after turning on the gas by the tap,
the small hood on the lamp should be held a little distance above the burner, when
the gas passes up through the hood before mentioned, then in a small-stream
through the horizontal-tube, this stream comes in contact with the lamp flame and
becomes ignited, the flame of gas running. back through the tuber & hood totthe
burner. By this means a-gas jet-may be lighted without the use of a naked-light,
thus-meeting the second danger-mentioned above, and without extinguishing the
flame in the lamp.

COMPLETE SPECIFICATION.
-Improvements-in-Hand Lamps for Igniting Gas.
I, SAMUEL RILEY, 28 Carlton Street, Leicester, Ironmonger, 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 :-
This invention has reference to hand lamps for igniting gas.
It is a well known fact that injuries to the person often arise through moving
about a room or building during darkness without a light and also that the contents
of a building are often endangered by the practice of carrying naked lights about
for the purpose of lighting gas.
Now the object of this invention is to provide means which shall not only serve
the purpose of illuminating a room or building during darkness, but which may
also be used for the purpose of igniting gas jets without the necessity arising of
having to expose a naked light for such purpose.
This object is accomplished by a peculiar construction of hand lamp as herein-
after described and illustrated in the accompanying drawing of which
Figure 1 is an elevation with the door partially opened and Figure 2 a central
vertical section.
The essential feature of the invention consists in applying to, or constructing a
lamp with, one or more hoods or equivalents on the exterior of the lamp and
communicating with the interior thereof.

page_text: Referring to the drawing A represents the lamp, B the door, C the oil reservoir,
D the wick, and E the reflector.
F represents the hood which is preferably semiconical in shape and may be
either attached to or formed integrally with preferably the side or sides of the
lamp.
The hood communicates with the interior of the lamp by means of an opening A¹
in the side of the latter, having a short, preferably horizontal tube, pipe or
equivalent G fixed thereover, to form a continuation of same and direct the gas
into the lamp and in contact with the flame as hereinafter described.
In using the lamp for igniting gas jets the wick is lighted and the hood placed
over the burner from which the gas is issuing, the stream of gas then passes up the
hood through the tube G coming into contact with the lamp flame and
immediately harks back, following the stream of gas through the tube and hood to
its source, viz. :-the burner, when it immediately becomes ignited.
It is obvious that any convenient form of hand lamp may be employed for the
purpose of this invention and also that the shape of the hood and tube and the
direction thereof may be varied within any reasonable limits so long as the ignition
of the gas is effected.
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 :-
.1. In a hand lamp the provision of means for enabling it to be used for the
purpose of igniting gas jets without exposing the naked light.
2. In a hand lamp the combination of one or more openings or passages com-
municating with the interior thereof and one or more hoods such as F or equivalent
substantially as and for the purpose described and illustrated in the accompanying
drawing.
