Improvements in Lamps for Burning Hydrocarbon Oils.
I JOHN SANKEY of 181 Monument Road Birmingham in the County of Warwick
Chandelier Maker, and I AARON Bonehill Back 43 Beech Street Birmingham in
the County of Warwick Chaser, do hereby declare the nature of our Invention for
IMPROVEMENTS IN LAMPS FOR BURNING LIGHT OR VOLATILE OILS to be as follows:-
The object of our Invention is to provide ready access to the Wicks of such Lamps
for trimming or lighting without removal of the Globe or Chimney and our Invention
consists in the application of one or more Wheels in conjunction with one or more
Screwed Rods to raise sustain and lower the Gallery or Globe Holder of the said
Lamps.
We will describe the application of our improvements to a Duplex Burner Lamp.
Attached to the gallery of the said Lamp are one or more Screwed rods, whilst in the
body of the Burner are placed one or more Screwed Cog-wheels, these said Screwed
Cog Wheels have a rotary motion around the said Screwed Rod or Rods attached to
the said Gallery, to gain this rotary motion the said Wheel or Wheels are placed
within another wheel which lies horizontally within the Body of the said Burner. Wo
then place a Wheel in a perpendicular position upon the Horizontal wheel with a
spindle attached to it. And by the rotating of the said Spindle the Horizontal wheel
revolves and so causes the said Screwed Cog Wheels to revolve around the said
screwed rod or rods attached to the said Gallery and thus raise sustain and lower the
Gallery of the said Burner Lamp.

Improvements in Lamps for Burning Hydro-carbon Oils.
I JOHN SANKEY of 181 Monument Road Birmingham in the County of Warwick
Chandelier Maker and I AARON BONEHILL of 42 Alston Street Ladywood Birming-
ham in the county of Warwick Chaser do hereby declare the nature of our
Invention to be as follows:-
The object of our invention is to provide ready access to the wicks of such lamps 5
for trimming or lighting without removal of the Globe or Chimney. And our Inven-
tion consists in the application of one or more wheels in conjunction with one or more
screwed rods to raise sustain and lower the Gallery or Globe Holder of the said
Lamp.
We will describe the application of our Improvements to a duplex Burner lamp 1
Attached to the Gallery of the said lamp are one or more screwed rods whilst in the
Body of the Burner are placed one or more screwed cog wheels these said screwed
cog wheels have a rotary motion around the said screwed rods or rods attached to the
said Gallery, to gain this rotary motion the said wheel or wheels are placed within
another wheel which lies horizontaly within the body of the said Burner We then place
a wheel in a perpendicular position with a spindle attached to it upon the Horizontal
wheel and by the rotating of the said Spindle the Horizontal wheel revolves and so
causes the said screwed cog wheels to revolve around the said screwed rod or rods
attached to the said Gallery and thus raises sustains and lowers the Gallery of the said
Burner Lamp.
We will now proceed to describe with reference to the accompanying drawings the
manner in which our Invention is to be performed. Figure 1 is a vertical section of
part of a lamp embodying our invention. Attached to the Gallery of the said lamp are
two screwed rods A A these two screwed rods have a working action in two screwed
cog wheels B B these said cog wheels derive a rotary motion by being placed within a
larger cog wheel placed in the body of the said Burner CC to gain a rotary motion there
is placed on the large cog wheel C a small cog wheel with a spindle attached D. D.
When it is required to gain access to the wicks for trimming or lighting them the Gallery
or Globe Holder is raised by the rotating of the said spindle D D on the large cog
wheel CC which causes the said two screwed cog wheels B B to rotate around the
said two screwed rods which are placed on the said Gallery A A and thus ensures the
raising sustaining and lowering of the said Gallery or Globe Holder.
Figure 2 is a vertical section of part of a lamp shewing the Gallery or Globe
Holder a a raised by the rotating of the Spindle D D upon the large Cog wheel C C

the spindle by the rotating of which causes the wheel C C to rotate around the two
screwed cog wheels B B where are placed the two screwed rods attached to the
Gallery A A as shown and described on Figure 1.
Having now described the nature of our Invention and the manner in which the
same is to be performed we wish it to be understood that we claim as our Invention
for Improvements in Lamps for Burning Hydrocarbon Oils.
The Screwed Rods working by means of Cog Wheels as described and shown in
Figure 1 2. 3.
In witness whereof we the said John Sankey and Aaron Bonehill have hereunto
set our Hand and Seal this fifth day of April one thousand eight hundred and
eighty seven.
