CERTAIN IMPROVEMENTS IN LAMPS
Year: 1874

page_text: LETTERS PATENT to William Edward Teale, of Manchester, in the
County of Lancaster, Lamp Manufacturer, for the Invention of
"CERTAIN IMPROVEMENTS IN LAMPS."
Sealed the 7th July 1874, and dated the 15th January 1874.
PROVISIONAL SPECIFICATION left by the said William Edward Tealo
at the Office of the Commissioners of Patents, with his Petition,
on the 15th January 1874.
I, WILLIAM EDWARD TEALE, of Manchester, in the County of Lan-
5 caster, Lamp Manufacturer, do hereby declare the nature of the said
Invention for "CERTAIN IMPROVEMENTS IN LAMPS," to be as follows:-
―
The object of my Invention is to prevent the heating of light hydro-
carbon or other inflammable oils within the body of lamps in which
such materials are used.
In order to carry out my Invention I fix within the body of a lamp
two or more inetal tubes of different diameters, one tube extending from.
near the top of the lamp to within a short distance of the bottom of the
same, the said tube being held in position in the centre of the lamp by
means of corkwood, or other non-conducting substance.

page_text: Another tube I fix to the top of the lamp, into which I place a lamp
wick extending half way down its length, from which point I carry a
second wick through the first-named tube to the bottom of the lamp;
this last-named wick I secure in permanent position by means of pins
passing through the axis of the tubes through which the wick is
extended.
I fill up the space within the lamp with pieces of dry sponge,
which become saturated with whatever inflammable oil the lamp is
filled; whatever oil is not absorbed by the sponge I pour out of the
lamp, thereby avoiding spilling the oil in case of the lamp being
overturned.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Edward Teale in the Great Seal Patent
Office on the 14th July 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD TEALE, of Manchester, in the County of Lancaster, Lamp
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifteenth day of January, One thou-
sand eight hundred and seventy-four, in the thirty-seventh year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William Edward Teale, Her special license that I, the said
William Edward Teale, my executors, administrators, and assigns, or
such others as I, the said William Edward Teale, my executors, admi-
nistrators, or 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 "CERTAIN IMPROVEMENTS IN
LAMPS," upon the condition (amongst others) that I, the said William
Edward Teale, by an instrument in writing under my hand and seal,
should particularly describe and ascertain the nature of the said Inven-
tion, 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

page_text: NOW KNOW YE, that I, the said William Edward Teale, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the accompanying
Drawings, and to the letters and figures marked thereon, that is to
say:
The object of my Invention is to prevent the heating of light hydro-
carbon or other inflammable oils within the body of lamps in which
such materials are used.
In order to carry out my Invention I fix within the body of a lamp
two or more metal tubes of different diameters, one tube extending from
near the top of the lamp to within a short distance of the bottom of the
same, the said tube being held in position in the centre of the lamp by
means of corkwood, or other non-conducting substance.
Another tube I fix to the top of the lamp, into which I place a lamp
wick extending half way down its length, from which point I carry a
second wick through the first-named tube to the bottom of the lamp;
this last-named wick I secure in permanent position by means of pins
passing through the axis of the tube through which the wick is
extended.
I fill up the space within the lamp with pieces of dry sponge, which
become saturated with whatever inflammable oil the lamp is filled; what-
ever oil is not absorbed by the sponge I pour out of the lamp, thereby
avoiding spilling the oil in case of the lamp being overturned.
And in order that the said Invention may be fully understood I shall
now proceed more particularly to describe the same, and for that purpose
I shall refer to the several Figures on the Sheet of Drawings hereunto
annexed, the same letters of reference indicating corresponding parts
throughout corresponding Figures.
Figure 1 shews an elevation; Figure 2, a plan; and Figure 3, an
enlarged section of an ordinary candle lamp.
a is the outer casing of a lamp; b is a metal tube, secured in
position by its fitting tightly in the wooden diaphram d; c is another

page_text: metal tube, also secured in position by its fitting tightly in the wooden
diaphram d; the. said tube c is also soldered to the top of the lamp;
e is a lamp wick extending from the top of the lamp down to about one
half the length of the tube c; f is a lamp wick secured within the tube c
by means of two pins, the said wick f extending through the tube 6 to 5
the bottom of the lamp; the space within the lamp I fill with dry
sponge; h is an ordinary screw cap, through which the lamp is filled
with whatever inflammable material is to be used within the lamp; the
lamp being filled with the required material and the surplus poured
away, leaving the sponge saturated, the wick conducts the vapours 1
of the inflammable oil to the extent of its length, when the wick e,
being in contact with the wick f, receives therefrom the said vapour
and conducts the same to the top of the tube c, where the vapour may
be ignited.
Having now described and particularly ascertained the nature of the 1
said Invention, and in what manner the same is or may be carried
into effect, I would observe in conclusion that what I consider to be
novel and original and therefore claim as secured to me by the said
Letters Patent is,―
First. The arrangement and combination of metal tubes fixed within 2
the body of lamps in the manner and for the purpose herein-before
described and illustrated.
Secondly. The arrangement and combination of lamp wicks within
metal tubes, used in the manner and for the purpose herein-before
described and illustrated in the accompanying Sheet of Drawings.
In witness whereof, I, the said William Edward Teale, have here-
unto set my hand and seal, this Thirteenth day of July, in the
year of our Lord One thousand eight hundred and seventy-
four.
