CERTAIN NEW IMPROVE- MENTS IN THE CONSTRUCTION OF LAMPS
Year: 1827

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
PARKER, of Argyll Place, Argyll Street, in the City of Westminster, and
County of Middlesex, Bronzist, send greeting.
WHEREAS His present Majesty King George the Fourth, in and by His
Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Third day of February last, for Himself, His heirs and
successors, did give and grant unto me, the said Samuel Parker, His
especial licence, full power, sole privilege and authority, that I, the said
Samuel Parker, my exors, adiñors, and assigns, and every of them, by myself
and themselves, or by my and
by my and their deputy or deputies, servants or agents, or
such others as I, the said Samuel Parker, my exors, adñiors, or assigns,
should at any time agree with, and no others, from time to time and at all
times thereafter during the term of years therein unexpired, should and
lawfully might make, use, exercise, and vend, within England, Wales, and
the Town of Berwick-upon-Tweed, my Invention of "CERTAIN NEW IMPROVE-
MENTS IN THE CONSTRUCTION OF LAMPS;" in which said Letters Patent there is
contained a proviso obliging me, the said Samuel Parker, by an instrument in
writing under my hand and seal, particularly to describe and ascertain the
nature of my said Invention, and in what manner the same is to be performed,
and to cause the same to be inrolled in His Majesty's High Court of Chancery
within two calendar months from the date of the said recited Letters Patent,
as in and by the same, reference being thereto had, will more fully appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Samuel Parker, do hereby declare that the nature of my said Invention and
the manner in which the same is to be performed, are particularly described
and ascertained in and by the Drawing hereunto annexed, and the following
description thereof (that is to say) :-
In the Drawing Figure 1 is a section of an Argand lamp A, to be fitted
up with a spiral wick holder in it as usual, but which latter is not shewn in
the Drawing. B, the ring reservoir for the oil. C, the tube which connects
the lamp with the ring reservoir and conveys oil to the lamp. D, D, a solid
glass bowl, urn, or vase, upon and within which the lamp is supported and
contained. E, the stem of the bowl, surrounded with and connected to a
screwed metal socket F, by means of which the lamp is affixed upon the
top of the metal pillar or other support of the lamp. G, G, a metal ring
mounted upon the rim or border of the bowl D, D, and perforated with holes
all around it. H, H, a metal ring forming the upper part of the oil reservoir
B, and lodging within a recess formed to receive it in the top of the ring G, G.
I, the glass chimney of the lamp supported upon the glass holder J, J, and
lodged within a ring or border formed upon the glass holder to receive it. K, K,
a middle coronal glass, also supported upon the glass holder J, and which
is extended in diameter to receive it. Figure 2 is a plan and Figure 3 a
section of the glass holder J, J. L, L, L, L, four upright metal guides to
direct the coronal glass K to its proper situation upon the glass holder, two of
which are shewn in Figure 1, three of them in Figure 3, and all four of them
in Figure 2. Figure 4 represents the lower part of the coronal glass K
having a metal ring M, M, firmly cemented to it; from the lower edge of this
ring a metal pin or stud N projects downwards and which said pin lodges or
rests within one of the gaps 0, 0, which are made around the inside of the
external border of the glass holder J, J, and as shewn in Figure 2. By this
means on turning the coronal glass K, K, with the hand it also turns the
glass holder J, J, and thus raises or lowers the wick of the lamp as may be
required; the top of the coronal glass K, K, is spread outwardly so as not to
be heated by the flame of the lamp. The ring reservoir B is supplied with
oil by means of the cock P; the conical socket of which Q is soldered firmly
into the reservoir, and it has two orifices R and S, the one above the other as.
shewn in the outer view of it, Figure 5. The conical plug of the cock T has
likewise an upper and lower orifice in it U, V, as shewn in the section of
it, Figure 6, made to correspond with the orifices in the socket of the cock;
but not the one above the other as in the socket, but on the contrary, placed
nearly opposite to each other. There is also a division plate W, formed in the
Q

page_text: middle of the plug, as shewn in Figure 1 and 6; by these means when the
uppermost hole in the plug U is brought into the direction of the uppermost
hole in the socket R, by means of the handle or lever of the cock X, the oil
may be poured in at the top of the cock, and will flow into the ring reservoir,
the air in it escaping at the same time through another orifice Y shewn by
dotten lines in Figure 7 and 8, made through the plug and socket for that
purpose, and through a notch or gap also made in the side of the plug commu-
nicating with the hole Y, in both the plug and the socket. Figure 9 is a
section of the socket of the cock Q, shewing the hole Y in it. Upon bringing
the lower hole V in the plug into the direction of the lower hole S in the
socket of the cock by again turning the handle X, and as shewn in Figure 10,
the oil will flow down the tube C to supply the lamp on the fountain principle,
the air entering through a pipe Z, Figure 1, which is placed at a proper height
or level, and communicates with the external air. The plug of the cock is
retained in its place in the socket by a covering ring a, shewn in the section
in Figure 1, and in the plan Figure 11, and is regulated in its motion both
ways by a circular recess 6 made partly around the top of the socket into
which a pin or stud screwed into the side of the plug fits and is stopped
against each end of the recess; the cap a is held in its place upon the top of
the socket by two or more screws c, c. This cock, however, having already been
applied by me to another lamp made me and called the Saturn lamp, I do
not hereby claim the construction of it as my Invention, but only its applica-
tion to the present lamp, and which lamp I intend to designate by the name of
the Argyll lamp. From the arrangement above described the air is conducted
to supply the flame of the lamp in such manner as to prevent the apparatus
from becoming too hot to be conveniently handled, and the oil is preserved
at that temperature which is most conducive to the lamp burning well. I also
obtain a most convenient mode of raising and lowering the wick of the lamp,
by turning the coronal glass round either way with the hand, and which said
glass, resting upon and turning the glass holder, thus regulates the height of
the wick, and this is effected without soiling the fingers; whilst the coronal
glass being widened above, as above described, is always kept cool; the coronal
glass likewise preserves the supply of air from becoming heated before it
comes into contact with the flame, and the currents of air preserve the reservoir
for oil at a moderate temperature, the one passing around and the other within
it, and also keep the glass bowl, urn, or vase cool at the same time. Another
advantage is obtained by employing the solid glass bowl, urn, or vase D, D, as
I thereby prevent the spilling of the oil.
I do not mean or intend hereby to claim as my Inventions any of the
