Lanark, North Britain, Paraffine Lamp Manufacturer, for the
Invention of "IMPROVEMENTS IN LAMPS.”
Invention of "IMPROVEMENTS IN LAMPS.'
"
PROVISIONAL SPECIFICATION left by the said John Young at the
Office of the Commissioners of Patents, with his Petition, on the
6th July 1870.
I, JOHN YOUNG, of Glasgow, in the County of Lanark, North Britain,
Paraffine Lamp Manufacturer, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN LAMPS," to be as follows, that is
to say:-
This Invention relates to lamps designed more particularly for
burning paraffine and similar oils, and its object is to permit of the
use of different kinds of glasses with the same lamp. Thus in some
paraffine lamps, as hitherto constructed, arrangements are made for
applying a globe without an internal chimney, whilst in others the

page_text: arrangements are such that both globe and chimney must always be used.
A lamp made according to the present Invention, however, can be used
with a globe alone or with both globe and chimney, whichever may be
found most convenient or best adapted to the particular kind of oil
in use.
In carrying out the Invention the burner is made with a single cone,
under which air is admitted through perforations in an inverted conical
shell supporting the cone and two galleries. There are also perforations
for air in the lower part of the cone within the inner gallery, which is
adapted to receive either a globe when used by itself, or a chimney
when used with a globe, the globe being in the latter case supported on
the outer gallery. The globe to be used alone is, as is well understood,
of a form suited to that purpose, but by the present Invention has its
bottom shaped to fit the inner gallery.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 1
filed by the said John Young in the Great Seal Patent Office on
the 4th January 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
YOUNG, of Glasgow, in the County of Lanark, North Britain, Paraffine
Lamp Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixth day of July, in the year of our
Lord One thousand eight hundred and seventy, in the thirty-fourth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said John Young, Her special licence that I, the
said John Young, my executors, administrators, and assigns, or such
others as I, the said John Young, my executors, administrators, and
assigns, should at any time agree with, and no others, from time to
time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "IMPROVEMENTS IN LAMPS," upon the
condition (amongst others) that I, the said John Young, my executors
or administrators, by an instrument in writing under my, or their; or one
of their hands and seals, should particularly describe and ascertain the

page_text: nature of the said invention, and in what manner the same was to De
performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of
the said Letters Patent.
NOW KNOW YE, that I, the said John Young, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement in writing, reference being had to the accom-
panying Drawings, that is to say :—
My said Invention relates to lamps designed more particularly for
burning paraffine and similar oils, and its object is to permit of the
use of different kinds of glasses with the same lamp. Thus in some
paraffine lamps, as hitherto constructed, arrangements are made for
applying a globe without an internal chimney, whilst in others the
arrangements are such that a chimney with or without a globe must
always be used. A lamp made according to my present Invention,
however, can be used with a globe alone or with both globe and
chimney, whichever may be found most convenient or best adapted to
the particular kind of oil in use.
I obtain the desired result by a particular conformation and pro-
portioning of the parts forming the burner.
And in order that my said Invention, and the manner of performing
the same may be properly understood, I hereunto append a Sheet of
explanatory Drawings to be herein-after referred to, and representing
the essential parts of my improved lamp.
Figure 1 is a vertical section of the burner with a globe 1, but
without a chimney, whilst Figure 2 shows the burner in elevation with
a chimney and an external globe 3, the last being in section. The
burner is made with a single cone or dome 4, under which air is
admitted through perforations in an inverted conical shell 5 supporting
the cone and one or two galleries 6, 7; there are also perforations in
the lower part of the cone 4 within the inner gallery 6 for air to pass
up inside of the chimney 2 or globe 1. It is important to proportion
the parts of the burner as shown in the Drawing, and in particular
to set the wick tube 8 as nearly as possible in the position shown
relatively to the top of the cone 4. The burner may be made as shown
in Figure 1 without the outer gallery (7), and be used with a globe 1

page_text: of the kind shown in Figure 1, with a contracted upper part, or with a
wider top if covered with wire gauze; or the burner shown in Figure 1
may be used with a common chimney and without an external globe.
When the burner is fitted with the external gallery 7, as shown in
Figure 2, it may be used with the chimney 2 and external globe 3, or
The
instead of these with a globe 1 of the kind shown in Figure 1.
burner may be made in different sizes, the same proportions being
retained.
Having thus particularly described my said Invention, and the manner
in which the same is to be performed, I have to state that what I believe
to be novel and original and claim as secured to me by the herein-before
in part recited Letters Patent is, the constructing of the burners of oil
lamps so as to be usable with chimneys and globes, or with globes alone,
by shaping and proportioning the parts as shown on the accompanying
Drawing and herein-before described.
In witness whereof, I, the said John Young, have hereunto set
my hand and seal, this Thirty-first day of December, in the year
of our Lord One thousand eight hundred and seventy.
Witness,
EDMUND HUNT,
Patent Agent,
Glasgow.
