IMPROVEMENTS IN LAMPS
Year: 1862

page_text: LETTERS PATENT to Peter Shaw, of the City of Edinburgh, Gentleman,
for the Invention of "IMPROVEMENTS IN LAMPS."
Sealed the 5th August 1862, and dated the 7th February 1862.
PROVISIONAL SPECIFICATION left by the said Peter Shaw at the Office
of the Commissioners of Patents, with his Petition, on the 7th February
1862.
I, PETER SHAW, of the City of Edinburgh, Gentleman, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN LAMPS," to be as
follows:-
In lamps for burning paraffin oil and some other fluids, the vessel to contain
the oil is generally made of a bad conductor of heat, such as glass, to prevent
the oil being heated by the burning of the lamp; this circumscribes to a
certain extent the form and decoration of the lamp. Now I construct lamps
having the vessel to hold the oil made of glass or other bad conductor of heat,
and place this vessel wholly or partially within an outer covering of the form
and material required to suit the design of the artist, and when a metallic
tube or rod passes through or into the oil vessel, I cover such tube or rod with
a bad conductor of heat to prevent its contact with the oil.

by the said Peter Shaw in the Great Seal Patent Office on the 7th
August 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, PETER
SHAW, of the City of Edinburgh, Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of February, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Peter Shaw, Her special licence that I, the said Peter Shaw,
my executors, administrators, and assigns, or such others as I, the said
Peter Shaw, 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 Peter Shaw, 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 nature of the said Invention, and in what manner the same was to
be, 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 Peter Shaw, 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 state-
ment thereof, reference being had to the Drawings hereunto annexed, that
is to say:-
In lamps for burning paraffin oil and some other fluids, the vessel to contain
the oil is generally made of a bad conductor of heat; such as glass, to prevent
the oil being heated by the burning of the lamp; this circumscribes to a
certain extent the form and decoration of the lamp. Now I construct lamps
having the vessel to hold the oil made of glass or other bad conductor of heat,
and place this vessel wholly or partially within an outer covering of the form,
and material required to suit the design of the artist. When a metallic tube
or rod passes through or into the oil vessel, I cover such tube or rod with a
bad conductor of heat, to prevent its contact with the oil.
Figure 1 of the accompanying Drawings is a section of a lamp constructed

page_text: according to my Invention. a is the vessel for containing the oil, made of
some bad conductor of heat, such as glass or stoneware, it is inserted in and
secured to an external vase or holder b.
Figure 2 is the section of a lamp, in which an air tube passing through the
oil vessel is employed. c is the air tube, and d is a ferrule or tube of glass or
other bad conductor of heat, extending round that portion of the tube c which
passes through the vessel a. The ferrule d is fixed to the tube c by cement.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim as my "Improve-
ments in Lamps,"
First, constructing lamps for burning paraffin oil and some other fluids with
a vessel for containing the oil, made of glass or other bad conductor of heat,
surrounded with a vase or holder capable of being ornamented with any
desired design, or of being made of any required shape, all as herein-before
described.
Second, surrounding the air tube or rod which passes through the oil vessel
with a ferrule or tube of glass or some other bad conductor of heat, as herein-
before described.
In witness whereof, I, the said Peter Shaw, have hereunto set my hand
and seal, this. Fifth day of August, One thousand eight hundred and
sixty-two.
Witness,
F. C. BAIRD,
Lochrin.
PETER SHAW. (L.S.)
