the Commissioners of Patents, with his Petition, on the 25th April
1865.
I, NICHOLAS SIDLY, of St. Laurence, near Bodmin, in the County of
Cornwall, do hereby declare the nature of the said Invention for "IMPROVED
APPARATUS FOR POURING AND DECANTING LIQUIDS," to be as follows:-
This Invention relates to certain improved methods of constructing appa-
ratus for decanting or pouring liquids, and consists mainly in so arranging
the vessels employed for that purpose that the air which must be contained
therein in order to impel the outflow of the liquid shall enter at or near the
extremity of the spout, so that the aperture of the spout being placed at the
point or level to which the liquid is desired to rise, the influx of air will be
stopped by the rise of the liquid to such point or level, and the further outflow
thus prevented.
The mode of carrying this Invention into effect will be more clearly under-
stood by reference to the annexed Drawings.
Figure represents two forms of the apparatus. Without the air tube
indicated by the dotted lines, it consists of a shallow vessel having a spout of
the peculiar form represented.
The triangular stay a, b, c, between the spout and the body of the vessel
encloses a space the width of the spout, and holes being made at a and b in
the spout and in the vessel within the stay, the air passes more rapidly into

page_text: the vessel, securing thereby a faster flow of the liquid than when the air has
to pass the whole length of the spout. A hole is made at c within the stay
either in the spout or the vessel for the liquid to drain out of the spout within
the stay. Instead of employing this arrangement the same end may be
attained by means of a tube from a to b.
The same figure taken with the tube represented by the dotted lines shews
another form of the apparatus, the stay a, b, c, being applied for strength in
the ordinary way. The air tube extends from the extremity of the spout or
near thereto to the vessel, by preference to that part thereof which is occupied
by the air as the liquid flows out. The peculiar form of the spout is to admit
of its being placed in the vessel to be filled before pouring out the liquid,
and to allow the vessel to be lowered before the spout is raised out of the
liquid.
Figure 2 represents a similar application of the Invention to another form
of vessel, the dotted lines a, a, representing a different position in which the
air tube may be placed, and the dotted lines b, b, indicating the position of the
top handle on the opposite side of the vessel.
Figure 3 is a vessel shewing different positions in which the top may be
placed.
Figures 4, 5, and 9 are different forms of the apparatus adapted to
Figure 3, and consist of tubes of different forms. These forms of apparatus
may be made with or without the air tube a, a, a, which is represented in the
Figures parallel with and attached to the main tube. Figure 10 is a section
of Figure 9 on the line b, c, shewing the form preferred for the air channel
a, a, a. Figures 4 and 5 are adapted to the perpendicular top of Figure 3,
and Figure 9 to either a, b, or c.
Figures 6, 7, and 8 shew the construction of the apparatus fitted with a
self-acting valve. a is a tube surrounded with cork or other suitable material
at one end, the opposite end being attached to the valve case or box b, which
is closed at one end. To the opposite end is attached a tube of smaller
diameter forming a seat for the valve c. A spiral or other spring d is placed
in the valve box for the purpose of keeping the valve on its seat. A wire
e, e, e, is attached to the valve c, by which it may be opened; this wire, as
shewn in section in Figure 7, is turned from the centre of the valve so as to
come in contact with the inside of the small tube, extending to the end or
orifice e; it is bent back so as to come in contact with the outside of the
same tube, and terininates in a right-angled projection.
A narrow opening is made in the end of the apparatus, as shewn at f in
Figure 8 (which represents the apparatus without the wire,) in which the

page_text: bend of the valve wire slides when opened or closed. A hole is made at.f,
Figures 6 and 8, through which the air is admitted slowly. As the liquid
rises over the orifice when in use, an air channel or tube may be substituted
for this hole extending from the position of the hole to the valve seat, so as
to be closed by the valve, as shewn by dotted lines, Figure 6. A pro-
jecting stud 9 is attached to the apparatus for the purpose of indicating the
point to which the liquid can rise when in use.
When the apparatus is used for supplying lamps or such like reservoirs,
the projecting end of the valve stem is placed on the top of the neck, and the
apparatus is then pressed into the reservoir until the stud 9 is below the
lower part of the neck. Being held in that position the liquid flows out
until it rises over the orifice and the hole f, when, in consequence of the
air no longer entering the vessel, it ceases flowing. The apparatus is then
raised quickly, so that the valve may close before any more liquid escapes.
