IMPROVE- MENTS IN THE CONSTRUCTION OF LAMP FEEDERS AND OTHER VESSELS FROM WHICH FLUID IS POURED OUT THROUGH TUBULAR SPOUTS
Year: 1864

page_text: LETTERS PATENT to Henry Edmonds, residing at Peel Lodge, Stokė
Road, Gosport, County of Southampton, for the Invention of "IMPROVE-
MENTS IN THE CONSTRUCTION OF LAMP FEEDERS AND OTHER VESSELS FROM
WHICH FLUID IS POURED OUT THROUGH TUBULAR SPOUTS."
Sealed the 9th June 1865, and dated the 22nd December 1864.
PROVISIONAL SPECIFICATION left by the said Henry Edmonds at the
Office of the Commissioners of Patents, with his Petition, on the 22nd
December 1864.
I, HENRY EDMONDS, residing at Peel Lodge, Stoke Road, Gosport, County
of Southampton, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE CONSTRUCTION OF LAMP FEEDERS AND OTHER VESSELS
FROM WHICH FLUID IS POURED OUT THROUGH TUBULAR SPOUTS," to be as
follows:
It consists in establishing an air communication between the outlet of the
spout of the vessel internally, or from a point at or near it externally, and the
interior of the vessel itself, the cover of which must be capable of being made
air-tight, the object of this is to regulate the flow of the liquid on pouring it
out, so that on its rising in the lamp or other receptacle to the height of the
mouth of the air pipe in or near the end of the spout, the further flowing of
the liquid shall cease, thus preventing the running over of the liquid and
diminishing the danger from the use of paraffine or other inflammable
fluids.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
EDMONDS, residing at Peel Lodge, Stoke Road, Gosport, County of South-
ampton, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of December, in the year of our
Lord One thousand eight hundred and sixty-four, in the twenty-eight year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Henry Edmonds, Her special licence that I, the said Henry
Edmonds, my executors, administrators, and assigns, or such others as I, the
said Henry Edmonds, 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
THE CONSTRUCTION OF LAMP FEEDERS AND OTHER VESSELS FROM WHICH FLUID IS
POURED OUT THROUGH TUBULAR SPOUTS," upon the condition (amongst others)
that I, the said Henry Edmonds, my executors or administrators, by an instru-
ment 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 Henry Edmonds, 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 and accompanying Drawings, that is to say :-
This Invention consists in establishing means for air communication between
the outlet of the spout of the lamp feeder, or any other vessel from which fluid
is poured out through a tubular spout, whether long or short, and the interior
of the vessel itself, which must either be air-tight or capable of being made
air-tight.
The object of this Invention is to enable lamps or other vessels to be filled
more readily without risk of the oil or other fluid overflowing, as the spout of
the feeder being inserted in the lamp or other vessel at the height it is desired
to fill it, and the fluid being poured out, directly it reaches the level of the air

page_text: channel in or near the outlet of the spout its further flow instantly ceases
owing to the access of air necessary to replace the outflowing fluid being
stopped, atmospheric pressure preventing its further flow.
The subjoined sketch of a lamp feeder of my improved construction will
explain this Invention more clearly. The dotted lines through the spout and
leading from it shew the course of the air pipe or channel for admitting air
into the interior of the vessel; this may either be entirely within the spout,
as shewn at a, a, or entirely outside of it, or partly within and partly without,
as at a, c.
To make the vessel air-tight I prefer to use a screw capsule, such as is used
for pocket drinking flasks, but any means may be used if found to be effectual
in making the vessel air-tight, such as corks or plugs, or the vessel may have
no upper outlet and be filled through the spout itself while the air communi-
cation remains open.
I claim the above Invention as specified in this description, whether applied
to lamp feeder or fillers, bottle fillers, or any other vessel from which fluid is
poured out through long or short tubular spouts.
In witness whereof I, the said Henry Edmonds, have hereunto set my
hand and seal, this 8th day of June, in the year of our Lord One
thousand eight hundred and sixty-five.
HENRY EDMONDS. (L.S.)
