Improvements in Oil Lamp Stoves.
We JOSEPH HINKS, and JAMES HINKS AND SON LIMITED, of Great Hampton
Street, in the City of Birmingham, Manufacturers, do hereby declare the nature
of this invention to be as follows:-
This invention relates to Improvements in Oil Lamp Stoves, and consists
primarily in the combination and arrangement of a central draught round wick
burner with a suspended metallic chimney in the manner and of the construction
as hereinafter explained.
Hitherto difficulty and danger have been experienced in stoves of this
character, by reason of the intense heat given off, being communicated so readily
to the oil container, and causing breakage to the glass chimneys used, and
thereby limiting very much the size of their flame.
In constructing this our improved stove, we provide an oil vessel or container,
preferably of a broad but shallow shape, upon which is mounted in the ordinary
manner a central draft burner. Around the bottom of the said vessel we
provide the air inlets which pass thence interiorly, direct to and through the
centre of the burner, impinging upon and feeding the inside of the flame.
The ordinary perforations in the body of the burner, afford the necessary
current to the outside of the flame. We now provide a lamp globe of rather
large dimensions whose lower part fits into a suitably shaped gallery upon the
burner. This globe is further shaped at its upper part to receive a metallic
cover having in its centre a hole. To the underside of this cover is secured a
centrally depending metallic chimney which reaches downwards to a suitable
distance from the flame; the lower part of such chimney further terminating in
a bell mouthed shape, so as the more readily to collect and conduct the heat
up the said chimney.
Supermounted upon the metallic cover aforesaid, is a metallic honnet for
further distributing the heated air given off from the burner. This bonnet is so
made, that when in position a heated air chamber is formed above the cover and
chimney, having perforations around its edge, and also outlets near and at its
raised central part. The tendency of the heated air is to escape up through
the elevated central opening or openings of the bonnet, and in so doing to create
a draft through the surrounding edge perforations and thereby the cooler air of
the room is drawn in and heated and then diffused into the room. This bonnet
is of a more or less ornamental character às may be desired.
By these means we produce a lamp stove in which the conduction of the
great heat given off from this class of burners to the burner and to the container
is broken the latter remaining quite cool, while the aggregate heat is diffused
from the upper part of the store into the room, and consequently burners' of a
much larger size can be employed than those of present use.

We JOSEPH HINKS, and JAMES HINKS AND SON LIMITED, of Great Hampton
Street, in the City of Birmingham Manufacturers 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 relates to Improvements in Oil Lamp Stoves, and consists
primarily in the combination and arrangement of a central draught round wick
burner with a suspended metallic chimney in the manner and of the construction
as hereinafter explained.
Hitherto difficulty and danger have been experienced in stoves of this character,
by reason of the intense heat given off, being communicated so readily to the
oil container, and causing breakage to the glass chimneys used, and thereby
limiting very much the size of their flame.
In order to more clearly explain this our invention we have appended here-
unto an illustrative sheet of drawings upon which are figures and numbers of
reference, similar numbers referring throughout the several views to the same
thing or part.
Fig. 1, is a general sectional elevation of this our invention.
Fig. 2, is a detailed view of the metallic bonnet.
Fig. 3, is a detailed view of the cover and chimney.
In constructing this our improved stove, we provide an oil vessel or con-
tainer 4, preferably of a broad but shallow shape, upon which is mounted in
the ordinary manner a central draft burner 5. Around the bottom of the said
vessel we provide the air inlets 6, which pass thence interiorly, direct to and
through the centre 7, of the burner, impinging upon and feeding the inside of
the flame, in the ordinary manner.
The ordinary perforations 8, in the body of the burner, afford the necessary
current to the outside of the flame. We now provide a lamp globe 9, of rather
large dimensions whose lower part fits into a suitably shaped gallery 10 upon
the burner. This globe is further shaped at its upper part to receive a metallic
cover 11, having in its centre a hole 12. To the underside of this cover is
secured a centrally depending metallic chimney 13, which reaches downwards to
a suitable distance from the flame; the lower part 14, of such chimney further
terminating in a bell mouthed shape, so as the more readily to collect and
conduct the heat up the said chimney.
Supermounted upon the metallic cover 11, aforesaid, is a metallic bonnet 15,
for further distributing the heated air given off from the burner. This bonnet
is so made, that when in position as shown in Fig. 1, a heated air chamber 16,
is formed above the cover and chimney, having perforations 17 and 18, around
its edge, and also outlets 19, near and at its raised central part. The top of
the chimney terminates about midway in height between the perforations 18
and 19. The tendency of the heated air from the burner is to escape up through
the elevated central openings 19, of the bonnet, and in so doing to create an
indraught through the surrounding edge perforations 17 & 18, and thereby the
cooler air of the room is drawn in and heated and then diffused through the
openings 19, back into the room. This bonnet is of a more or less ornamental
character as may be desired.
By these means we produce a lamp stove in which the conduction to the
burner and to the container of the great heat given off from this class of
burner is broken, the container remaining quite cool, while the aggregate heat
is diffused from the upper part of the stove into the room, and consequently
burners of a much larger size can be employed than those of present use.

page_text: Having now particularly described and ascertained the nature of this our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. In oil lamp stoves, the combination with the container 4, having inlets 6,.
and burner 5 and globe 9, the cover 11, carrying the depending chimney 13, of
the bonnet 15, having perforations 17 and 19 all substantially as described and
shown.
2. In oil lamp stoves having the container 4, burner 5, globe 9 and chimney 13,
the combination and arrangement of the position of the top of the said chimney
with the perforations 17, 18, and 19, as and for the purposes specified.
