Year: 1884

I, JOHN SANKEY, of 30, Wood Street, Ladywood, Birminghain, in the County
of Warwick, Chandelier Maker, do hereby declare the nature of my invention for
IMPROVEMENTS IN LAMPS FOR BURNING HYDRO-CARBON OILS, to be as follows :-
The object of my invention is to provide access to the wicks of such lamps for
trimming or lighting without removal of the globe or chimney; and my invention
consists in the application of screw threads or inclines to raise, sustain, and lower
the galleries or globe holders of the said lamps.
I will describe the application of my improvements to a duplex burner lamp,
though they are equally applicable to other lamps. Within that part of the burner
which surrounds the wick holders, and is beneath the gallery, I place screw threads
or inclines. These screw threads or inclines may have a motion of rotation round
the wick holders, or may be fixed to the burner. Suitable pieces are fitted to slide
on the screw threads or inclines, and these sliding pieces are attached to or abut
against the gallery or parts connected to the said gallery.
If the screw threads or inclines be moved in the direction of rotation, the gallery
will be moved up or down by the vertical movement of the sliding pieces. If the
screw threads or inclines be fixed, a motion of the sliding pieces on the said screw
threads or inclines will cause vertical motion of the gallery as before. It is to be
understood that, for the purposes of my invention, it is indifferent whether the
screw threads or inclines be movable or stationary; for, so long as the motion of
the sliding pieces on the said screw threads or inclines be obtained, vertical move-
ment of the gallery will ensue: and the motion on the said screw threads or
inclines may be obtained either by moving the sliding pieces along the screw
threads or inclines, or moving the said screw threads or inclines under the said
sliding pieces. I have described the screw threads or inclines as placed inside part
of the burner; but they may also be placed on the outside of the burner. I vary
the pitch of the screw threads or inclines at certain points to better control the
raising, sustaining, and lowering of the gallery or globe holder.

JOHN SANKEY 30 Wood Street Ladywood, Birmingham in the county of
Warwick, Chandelier Maker do hereby declare the nature of .my invention for
IMPROVEMENTS IN LAMPS FOR BURNING HYDRO-CARBON OILS and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
The object of my Invention, is to provide ready access to the wicks of such
lamps, for trimming, or lighting, without removal of the Globe, or chimney. And
my Invention consists, in the application of Screw threads, or Inclines to raise,
Bustain, and lower, the Galleries or Globe holders of the said Lamps.
I will describe the application of my improvements, to a Duplex Burner Lamp.
Within that part of the Burner which surround the Wick Holders, and is beneath
the Gallery, I place Screw threads or Inclines, these Screw Threads or Inclines may
have a motion of rotation, round the Wick holders, or may be fixed to the Burner,
Suitable peices are fitted to slide on the Screw threads, or Inclines, and these
sliding peices, are attached to or abut against the Gallery or parts connected to
the said Gallery.
If the Screw-threads or Inclines, be moved in the direction of rotation, the
Gallery will be moved, up or down, by the vertical movement of the sliding peices.
If Screw Threads or Inclines be fixed, a motion of the sliding peices on the said
Screw threads or Inclines will cause vertical movement of the Gallery as before.
It is to be understood, that for the purposes of my Invention, it is indifferent,
whether Screw threads, or Inclines, be moveable or stationary, for so long as
motion of the sliding peices, on the said Screw threads or Inclines, be obtained,
vertical movement of the Gallery will ensue, and the motion on the said Screw
threads or Inclines, may be obtained, either by moving the sliding peices along the
screw threads, or Inclines. Or moving the said Screw threads or Inclines, under
the said sliding peices.
I have described the Screw threads or Inclines, as placed inside part of the
Burner. But they may be placed on the outside of the Burner.
I vary the pitch of the Screw-threads or Inclines, at certain points to better
control the raising sustaining, and lowering, of the Gallery or Globe Holder.
I will now proceed to describe, with reference to the accompanying Drawings,
the manner in which my Invention is to be performed.
Figure 1 is a vertical section of part of a Lamp embodying my Invention,
Around the Wick-holders, A. A are placed Screw threads or Inclines B. B attached
to B. B. is a ring C. C.
When it is required to gain access to the Wicks for trimming them, or for
lighting the Lamp, the Gallery or Globe holder is raised by the rotating of the
ring C. C. suitable peices being attached to the Guide rods D. D. which slide up
the Screw threads or Inclines B B.
Figure 2 is a vertical section of part of a Lamp showing the Gallery or Globe
holder A. A. raised by the rotating of the Screw threads or Inclines B B beneath

rotating movement around the Wick holders, as shown in Figure 1. A A.
I am aware that a sliding Gallery for supporting the Globe and Chimney, has
been used proir to the date of my Patent and I wish it to be understood that I lay
no claim to a Sliding Gallery excepting in the respects herein after pointed out.
Having now described the nature of my Invention and the manner in which the
same is to be performed I wish it to be understood that I claim as my Invention
For Improvements in Lamps for burning Hydro-carbon Oils the Skeleton
Screw-threads or Inclines working inside the Burner around the wick holders in
conjunction with the Guide rods, as described and shown in Figure 1. 2. and 3.
In witness whereof I the said John Sankey have hereunto set my hand and
seal this First day of August in the year of our Lord One thousand eight
hundred and eighty five.
