PROVISIONAL SPECIFICATION.
Improvements in or relating to Lamp Burners.
We, JOHN JACKSON WRIGHT, Cycle Manufacturer, and THOMAS SENDALL,
Cycle Manufacturer, both of 27 Newgate Street Bishop Auckland in the
County of Durham, do hereby declare the nature of this invention to be as
follows:-
This invention has reference to improvements in or relating to lamp burners
and may consist in the provision in combination with the ordinary burner of an
outer shell or casing of brass or other suitable material adapted to fit over and lie
close to the burner.
The said casing may be formed with its central parts more or less depressed and
its extremities relatively elevated the effect of which construction is to greatly
improve the brilliancy of the light to prevent smoking and to enlarge and improve
the form of the flame.
The casing may be made a true fit over the burner or as part thereof or
the burner may be modified in form if desired to suit the form of the new
outer casing.
The invention is applicable to any ordinary burners in any ordinary description
of lamp.
Burners may where suitable be made or converted as and for the purposes above
described.

Improvements in or relating to Lamp Burners.
We, JOHN JACKSON WRIGHT, Cycle Manufacturer and THOMAS SENDALL
Cycle Manufacturer both of 27 Newgate Street, Bishop Auckland in the
County of Durham, 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 improvements in or relating to lamp burners and
may consist in the provision in combination with the ordinary burner of an outer
shell or casing of brass or other suitable naterial adapted to fit over and lie close
to the burner.
The said casing may be formed with its central parts more or less depressed and
its extremities relatively elevated the effect of which construction is to greatly
improve the brilliancy of the light to prevent smoking and to enlarge and improve
the form of the flame.
The casing may be made a true fit over the burner or as part thereof or
the burner may be modified in form if desired to suit the form of the new

page_text: The invention is applicable to any ordinary burners in any ordinary description
of lamp.
Burners may where suitable be made or converted as and for the purposes above
described.
We will fully describe our invention with reference to the accompanying
drawings in which Figure 1 shows a plan view and Figure 2 a side view,
Figures 3 and 4 being enlarged central longitudinal and transverse sectional views
of the improved burner as applied for example to a cycle lamp reservoir and in the
following description like marks of reference indicate like parts.
Referring to the drawings a is the outer shell or casing forming the improved
burner above referred to shown fitted tightly over the old or ordinary shaped
burner. It will be seen that the central portion al of the improved burner
is depressed and that the extremities a² are relatively elevated the effects of which
construction are as already above described.
R is the oil reservoir and S a spindle fitted and conveniently arranged in any
suitable manner for the purpose of adjusting the level of the wick W which is cut
more or less to the shape of the burner as shown in Figure 2.
The dotted lines d in Figure 2 are intended to illustrate the concentrated form
of flame which the improved burner has the effect of producing.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. Forming the burners of lamps with a central depressed portion such as a¹ and
relatively elevated extremities such as a² the several parts being arranged and
adapted for use substantially as and for the purposes herein described and illustrated
in the accompanying drawings.
2. The improvements in lamp burners substantially as herein particularly set
forth.
