Year: 1863

page_text: LETTERS PATENT to Harvey Brown, of the City of New York, in the
United States of America, at present residing in King Street, Cheapside,
in the City of London, Gentleman, for the Invention of "IMPROVEMENTS
IN BURNERS FOR LAMPS FOR BURNING OILS OR FLUIDS."
Sealed the 12th January 1864, and dated the 13th August 1863.
PROVISIONAL SPECIFICATION left by the said Harvey Brown at the
Office of the Commissioners of Patents, with his Petition, on the
13th August 1863.
I, HARVEY BROWN, of the City of New York, in the United States of
America, at present residing in King Street, Cheapside, in the City of London,
Gentleman, do hereby declare the nature of the said Invention for "Ix-
PROVEMENTS IN BURNERS FOR LAMPS FOR BURNING OILS OR FLUIDS," to be as
follows:-
This Invention of "Improvements in Burners for Lamps for Burning Oils
or Fluids" is applicable to any form of lamps for burning oils or fluids. These
burners are made of brass with a screw upon the lower end for the purpose of
connection with a cap attached to the glass lamp in the usual way; or if the
body of the lamp be brass or other material, then the burner may be attached
in any other suitable manner. The burner, at the upper part, is enlarged
somewhat in the form of an inverted cone, to give room for the cog wheels
to operate within it, above which it is carried up direct a sufficient distance to
admit of orifices or holes by which air can be admitted to the flame. Abovo

page_text: this the circumference of the body of the burner may be enlarged for the
purpose of receiving the chimney and for attaching the springs to hold the
chimney in its place. Around this burner, in its upright part, is placed a
metal band having holes, in size, form, and number like those in the burner.
The object of this band is (by moving it round) to regulate the quantity of air
admitted to the flame. The wick tube is made in the usual form with spurs
passing through orifices in the side of the tube and meshing into the wick, and
by means of a burr on the outer end of the shaft, to which the spurs are
attached, these spurs move the wick. To this shaft a cog wheel is attached
just outside of the wick tube which connects with a similar cog wheel on a
short shaft that has spurs upon it that mesh into the wick on the opposite side
of the wick tube, and thereby the wick is moved with certainty. The chimney
is held in its place by semicircular springs attached to the upper part of the
burner. They are fastened, one on each side, with their back ends bent or coiled
in, their front ends being bent in and lapped. A pin provided with a head or
button passes through the burner and is fastened to the end of the inner
spring, and thus, in applying the chimney, its lower edge is placed under the
back or coiled ends of the springs, and the front or lapped ends of the springs
are moved out by the pin until the chimney drops down to its place; the
springs may then be released and the chimney is held firmly in its place.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said larvey Brown in the Great Seal Patent Office on the
13th February 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HARVEY
BROWN, of the City of New York, in the United States of America, at present
residing in King Street, Cheapside, in the City of London, Gentleman, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of August, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-seventh year of
Her reign, did for Herself, Her heirs and, successors, give and grant unto me,
the said Harvey Brown, Her special license that I, the said Harvey Brown,
my executors, administrators, and assigns, or such others as I, the said Harvey
Brown, 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,

page_text: and vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
BURNERS FOR LAMPS FOR BURNING OILS OR FLUIDS," upon the condition (amongst
others) that I, the said Harvey Brown, by an instrument in writing under
my hand and seal, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed, and causo
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 Harvey Brown, 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,
reference being had to the Drawings hereunto annexed, and to the letters and
figures marked thereon (that is to say) :-
This Invention of "Improvements in Burners for Lamps for Burning Oils
or Fluids is applicable to any form of lamps for burning any description of
oil or fluid that requires burners to promote and regulate its combustion. The
novel parts must be made of such size and forin of attachment as will admit of
the Invention being properly adapted to the particular kind of lamp to which
they are to be applied.
In the accompanying Drawings, Fig. 1 is a top or plan view of a lamp
constructed according to the present Invention; Fig. 2 is a side elevation, and
Fig. 3 a vertical section of the same; Fig. 4 is a perspective view of the top
of a lamp.
The spur wheels for raising or lowering the wick are mounted on the two
shafts A and A', upon which there are also the cog wheels D, D'. In Figures
2 and 3, B is the cap for enclosing the other parts, and having orifices made
therein. Within this cap there is another one B' provided with similar
orifices. C, C, are semicircular springs for holding on the glass chimney.
This burner is usually made of brass with a screw upon its lower end for the
purpose of connecting it with a cap to be attached to the glass or other reser-
voir of the lamp in the usual way; or if the body of the lamp be made of
brass or other material, then the burner may be so constructed as to be
attached to the lamp in any other convenient manner above the screw or other
mode of attachment. The burner is enlarged somewhat in the form of an
inverted cone or cup. This enlargement extends up a sufficient distanco to
give room for the cog wheels D, D', to operate within it. Above this point
the cap B' is carried up direct about half an inch, or a sufficient distance to
admit of orifices or holes to be made, in size, form, and number, as may
be desired, for the purpose of admitting air to the flame of the lamp when in

page_text: 'operation. Above this the circumference of the body of the burner may be
enlarged, as shewn in the Figures, and finished up in such size and form as
may be desired, for the purpose of receiving the chimney and for attaching the
springs c, c, to hold the chimney in its place. Around this burner, marked
B', in its upright part, is placed the external band or cover B, which is made
of brass or other material. This band is in width about equal to the upright
part of the burner, and is, as before mentioned, provided with orifices or holes,
in size, form, and number corresponding to those in the burner part B', which
is so arranged that it can be moved round horizontally. The object of this
band is to regulate the quantity of air admitted to the flame. The wick tube
is niade to receive a flat wick, and passes through the bottom of the burner in
the usual manner, and is made of suitable length above to place the wick right
with reference to the chimney and burner. For the purpose of moving the
wick up and down, the spur wheels, one or more, are placed on shafts A, A';
one end of one of them extends out, and is provided with a milled head at its
outer end for the purpose of rotating it, and thereby moving the wick in the
usual way. These spurs pass through orifices in the wick tube and mesh into
the wick. This shaft A has also the cog wheel D upon it just outside of the
edge of the wick tube. This cog wheel D meshes into the cog wheel D',
which is on the short shaft A' having the other spur wheel upon it, which
meshes into the wick on the opposite side of the wick tube, and thereby moves
the wick up with uniformity. There may be more or less of these spurs on
the shafts A and A', as desired. For the purpose of holding the chimney in
its place the springs C, C, made of spring brass or other suitable material,
are firmly attached, near the middle of their length, to the upright sides near
the top of the burner by means of rivets or their equivalent. The back ends
of these springs are bent in; the front ends are also bent in suitably and
overlap each other. A pin E with a head or other appliance upon its outer
end passes through a round orifice or slit in the burner and through oval or
long orifices in the lapped ends of the springs, and has a head or other appli-
ance likewise upon its inner end by which the springs are connected and made
to operate together, and thus, in applying the chimney, its edge is placed
under the back or coiled ends of the springs, and the front or lapped ends of
the springs are moved out by the pin E until the chimney drops down to its
place; the pin is then let go and the chimney is held firmly in its place. This
burner is made, in size, form, and finish, as may be desired, with such modi-
fication in the construction and use of the several parts above described as
may be found desirable, not departing from the nature and principles involved
therein.

page_text: Having now described my Invention of "Improvements in Burners for
Lamps for Burning Oils or Fluids," and having explained the manner of
carrying the same into effect, I claim as the Invention secured to me by
Letters Patent as aforesaid, the combination of parts herein set forth, including
the cap or band B, the double shafts A and A', provided with their spur
wheels, and the cog wheels D, D', on the respective shafts; also the use of
the springs C, C, all constructed and arranged substantially in the manner and
for the purposes set forth.
In witness whereof, I, the said Harvey Brown, have hereunto set my
hand and seal, the Thirtieth day of December, in the year of our Lord
One thousand eight hundred and sixty-three.
