COMPLETE SPECIFICATION.
Improvements in Oil Lamps of the kind known as Hand
Flare Lamps.
I, THOMAS STONE, of 15, High Street, Gravesend, in the County of Kent,
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:-
My invention has reference, to oil lamps of the kind known as hand flare. lamps.
These lamps are subjected to very rough usage and soon get out of order. Further
the oil is liable to leak from the lamp body either at the seams because of imperfect
soldering or at the holes through which in the ordinary construction the rivets
which fix the handles to the body are passed.
Now according to my invention I make the lamp body from one piece of metal
so that it is seamless, and attach the handle to the body in a manner which
entirely obviates the necessity for rivet holes. Further I provide improved means
of closing the lamp at top and a method of protecting and strengthening the
front of the lamp at and around the wick spout which is the part most subjected
to rough usage.
The accompanying drawings represent a lamp in which my improvements are
embodied.
Figure 1 is a vertical mid-section and Figure a front view of the lamp.
Figure 3 is a top view without the cover (which is, however, indicated by
dots) and with the handle in section. Figure 4 is a section on the line x x of
Figure 1 and Figure 5 is a view of the underside of the cover.
a a represent the lamp body which together with the bottom is stamped in one
piece without seam by incans of any suitable stamping machinery. is the upper
part of the lamp soldered to the body a and d is a protecting wire soldered around
the bottom. e is the handle; this handle instead of being rivetted as usual directly
to the body a is first secured by rivets to metal strips gg which are then soldered
to the exterior of the body a as shown. The handle e is thus fixed to the body a
without any holes having been formed in the latter for the purpose. is the wick
spout secured to the body a in any ordinary manner and is the usual shield which
is likewise secured to the front of the body in the ordinary way.
As the spout h
and the lamp body below the spout are the parts that are most subjected to rough
usage, I provide them with a protection in the form of a metal guard k which
encloses a space around the inner end of the spout in front of the body a and for
greater strength and also to give a better appearance I prefer to corrugate the
guard as shown. This guard not only protects the body and spout from direct
blows at and near the inner end of the spout but also at its upper part serves as
a bracket or stay to protect the lamp from the effects of blows against the spout
nearer its outer end.
For the purpose of readily and securely closing the top of the lamp I form at
the side of the central opening in the upper part three (or other number of)
gaps and employ a cover or cap m which has on its underside a corresponding
number of tongues n n which are preferably formed in a piece with a ring
soldered to the cover. The tongues n n are either somewhat thicker at one edge
than at the other or somewhat inclined from the horizontal plane. In order to
secure the cover the tongues n n are passed down through the gaps and the
cover is then given a partial turn by means of its handle y, the effect of which is
that the tongues owing to the differential thickness of their two edges, or to their
inclination, become by a sort of wedge action jammed and held against the underside
of the edge of the central opening in the part c. The cover m is secured to the
body a by a chain r.

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 in respect of lamps of the kind herein referred to is:-
1. The mode of securing the handle to the body which consists in first securing
the handles to metal strips (such as g) and then soldering these strips to the body,
substantially as hereinbefore described.
2. The combination, with a seamless body, of a handle secured to such body
without the forming of any rivet or like holes in the body, substantially as herein-
before described.
3. The combination with the lamp body and spout of a bracket-guard or stay-
guard (such as ) substantially as and for the purpose hereinbefore described.
4. The combination with gaps around the central opening in the upper part of
the lamp, of a cover or cap having a corresponding number of tongues which are
first passed down through the gaps and then by a partial turning motion of the
cover made to engage against the underside of the edge of the said central opening,
substantially as hereinbefore described.
5. The improved lamp hereinbefore described and represented in the accompany-
ing drawings.
