AN IMPROVED BURNER FOR WICKS
Year: 1873

page_text: LETTERS PATENT to Albert Marcius Silber, of Wood Street, Cheapside,
and of Whitecross Street, both in the City of London, Merchant,
for the Invention of "AN IMPROVED BURNER FOR WICKS."
Sealed the 27th June 1873, and dated the 9th April 1873.
PROVISIONAL SPECIFICATION left by the said Albert Marcius Silber
at the Office of the Commissioners of Patents, with his Petition,
on the 9th April 1873.
I, ALBERT MARCIUS SILBER, of Wood Street, Cheapside, and of
Whitecross Street, both in the City of London, Merchant, do hereby
declare the nature of the said Invention for "AN IMPROVED BURNER FOR
WICKS," to be as follows:-
This burner consists of concentric tubes forming a wick case or wick
holder. At the bottom of this wick case or wick holder is a slot through
which a flat wick is drawn up by means of a rack and pinion. As the

page_text: wick is drawn between the concentric tubes it assumes an annular,
tubular, or cylindrical shape. The wick is so drawn up that the upper
annular or tubular portion is of less diameter than the lower (annular
or tubular) portion, and hence the upper portion of the wick, except
just at the top, is not in contact with the surface of the outer concentric
tube of the burner or wick holder, and hence space is left for the
formation of gas or gaseous products around the wick, and the wick is
prevented from carbonizing too rapidly.
A bell-mouthed air tube is fitted internally of the burner or wick
holder so as to rise within the wick, or there may be two or more of such
hell-mouthed internal air tubes. The tubes are formed with orifices
or air holes near the bottom, that is to say, in their periphery near the
lower part, and atmospheric air passes into the tubes through these
orifices, communication with the outer air being provided for the ad-
mission of such air through the outer case or shell of the burner which
receives air through orifices in a space between such shell or case and
the outer side of the wick holder, which space forms an air chamber
so that air may reach the interior of the bell-mouthed tubes through
the orifices.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Albert Marcius Silber in the Great Seal Patent
Office on the 9th October 1873,
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALBERT
MARCIUS SILBER, of Wood Street, Cheapside, and of Whitecross Street,
both in the City of London, Merchant, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Ninth day of April, in the year of our
Lord One thousand eight hundred and seventy-three, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Albert Marcius Silber, Her special

page_text: license that I, the said Albert Marcius Silber, my executors, admini-
strators, and assigns, or such others as I, the said Albert Marcius Silber,
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, exer-
cise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "AN IMPROVED
BURNER FOR WICKS," upon the condition (amongst others) that I, the
said Albert Marcius Silber, 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 month next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Albert Marcius Silber, 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 thereof, reference being had to the accom-
panying Drawings and to the letters and figures marked thereon, that
is to say:
-
This burner consists of concentric tubes forming a wick case or wick
holder. At the bottom of this wick case or wick holder is a slot through
which a wick is drawn up by means of a rack and pinion. As the
wick is drawn between the concentric tubes it assumes an annular
'tubular or cylindrical shape. The wick when so drawn up has its upper
annular or tubular portion of less diameter than the lower (annular
or tubular) portion, and hence the upper portion of the wick, except
just at the top, is not in contact with the surface of the outer con-
centric tube of the burner or wick holder, and thus space is left for the
formation of gas or gaseous products around the wick, and the wick
is prevented from carbonizing too rapidly.
A bell-mouthed air tube is fitted internally of the burner or wick
holder so as to stand within the wick, or there may be two or more of
such bell-mouthed internal air tubes. The tubes are formed with
orifices or air holes near the bottom, that is to say, in the periphery or
sides of the tubes at or near the lower part thereof, and atmospherio

page_text: air passes into the tubes through these orifices, communication with the
outer air being provided for the admission of such air through the outer
case or shell of the burner which receives air through orifices in a space
between such shell or case and the outer side of the wick holder, which
space forms an air chamber so that air may reach the interior of the
bell-mouthed tubes through the orifices.
An ordinary dome or curved cap is used at the upper part of the
between such shell or case and the outer side or ще WICK полиса, ишон
space forms an air chamber so that air may reach the interior of the 5
bell-mouthed tubes through the orifices.
An ordinary dome or curved cap is used at the upper part of the
burner.
The accompanying Drawings exemplify a burner constructed according
to my Invention.
Figure 1 is a front sectional elevation, and Figure 2 a transverse
vertical section of one modification of burner constructed according to
the Invention.
Figures 3 and 4 are elevations (Figure 4 being partly in section) of
another modification of my improved burner; Figure 5 is a bottom ]
plan; Figure 6 is a vertical section, and Figure 7 a horizontal section
through the line x, y, of Fig. 6.
Figures 3 to 7 inclusively are on a smaller scale to that of Figures 1
and 2.
A* is the wick holder or burner; W is the wick. It is drawn up :
and down by rack and pinion worked by a nurled thumb piece k, k.
The wick passes over a tubular piece b.
B, C, are bell-mouthed concentric air tubes inserted centrally of the
wick. Atmospheric air enters these tubes through orifices d, d, in the
sides of the tubes at the lower part thereof, and passes up through the
tubes centrally of the wick.
W is the wick, it is slotted so as to pass over the column b. It is a
tubular wick as shewn.
The air tubes B, O, instead of being bell-mouthed may be straight or
otherwise formed, but they are always placed in the burner as described.
e, e, are holes at the bottom of the burner for the passage of the gaseous
products of combustion.
Having now described the nature of the said Invention, and in what
manner the same may be performed, I declare that I claim, the improved
1

page_text: burner herein-before described in which there are one or more air tubes
receiving atmospheric air through apertures in their sides or peripheries
at the lower part thereof, substantially as described.
In witness whereof, I, the said Albert Marcius Silber, have here-
unto set my hand and seal, this Ninth day of October One
thousand eight hundred and seventy-three.
