Improvements in Oil Lamp Burners.
I, EDWIN CARPENTER BELLAMY, of 129 Pritchett Street, in the City of
Birmingham, Lamp Manufacturer, do hereby declare the nature of this my said
invention to be as follows:-
This invention relates to improvements in oil lamp burners and consists primarily
in the peculiar formation of the ignition chamber that is the chamber in which the
upper end of the wick or wicks is or are located; also the said formation in combination
with the exterior shell of the burner in which the necessary perforations are made for
the admission of air to the flame. The lower part of the burner is made much
as usual, having the wick tube or tubes emerging through upwards to the required
beight. Surrounding the wick tube is a conically shaped shell tapering inwards
upwardly, and having around its wall a number of comparatively large perforations.
These perforations are of a lateral oblong shape whose dividing bars of one row of
perforations are placed midway between those of the row beneath so as to reduce
conductivity of heat.
At the upper part of this shell is now placed a concave plate which dishes
downwards towards and around the wick tube, and further has a perforation on
each side of the wick, which leaves a parallel central strip of metal, while the other
or outside edge of the perforations follow the circular top of the shell. Upon this
upper edge is now placed the dome at whose crown is the usual perforation through
which the flame emerges.
By these means a narrow wick (say for instance one quarter of an inch wide) will
produce a flame three times wider and at the same time burn steady and resist
considerable draught.

Improvements in Oil Lamp Burners.
I, EDWIN CARPENTER BELLAMY, of 129 Pritchett Street, in the City of
Birmingham, Lamp Manufacturer, 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 burners and consists primarily
in the peculiar formation of the ignition chamber, that is, the chamber in which
the upper end of the wick or wicks is or are located; also the said formation in
combination with the exterior shell of the burner in which the necessary
perforations are made for the admission of air to the flame. In order to more

page_text: clearly explain this my invention I have appended hereunto an illustrative drawing
in which:
Fig. 1, is a sectional view in elevation and Fig. 2, a plan view (with the dome
removed) of a burner made according to this my invention.
Similar numbers of reference are used in each view to denote the same part.
The lower part 4 of the burner is made much as usual, having the wick tube 5
or tubes emerging through upwards to the required height. Surrounding the wick
tube is a conically shaped shell 6 tapering inwards upwardly, and having around
its wall a number of comparatively large perforations 7. These perforations are
of a lateral oblong shape whose dividing bars 8 of one row of perforations are
placed midway between those of the row beneath so as to reduce conductivity
of heat, from those parts near the flame to the lower portion of the burner
.body.
At the upper part of this shell is now placed a concave plate 9 which dishes
downwards towards and around the wick tube, and further has perforations 10, one
on each side of the wick, which leaves a parallel central strip of metal, while the
other or outside edge of the perforations follow the circular top of the shell. This
plate 9 is formed in one piece with the cone 6. Upon this upper edge is now fixed
the dome 11 at whose crown is the usual perforation 12 through which the flame
-emerges, thus making the chamber 13 in which burns the flame of the lamp.
By these means a narrow wick (say for instance one quarter of an inch wide) will
produce a flame very much wider say three times wider or thereabouts, and at the
-same time burn steady and resist considerable draught.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In oil lamp burners the use of the chamber 13 formed by the concave plate 9
having side perforations 10, and the dome 11, substantially as set forth and
:shown.
2. The combination in oil lamp burners with the body 4, cone 6 having
alternating perforations 7, dome 11, of the perforated concave plate 9, all
-substantially as set forth and shown.
Dated this 2nd day of April 1897.
