Improvements in Cans and other Vessels for Pouring out a Given
Quantity of Liquid.
1, WILLIAM LAWw, of Marston Trussell Rectory, Market Harborough, in the County
of Leicester, Clerk in Holy Orders, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
The object of this invention is the construction of a cheap and simple can or vessel
for pouring out a definite quantity of liquid, applicable for use for the distribution, in
definite quantities of fluid disinfectants for domestic sanitary purposes, as well as for
the watering of plants, or for delivering measured quantities of any liquid, that
may be required, for other purposes.
The can
or vessel is filled from the bottom and is provided with an auxiliary
receptacle communicating with the main reservoir by two small holes about of
an inch in diameter one above the other. Through the bottom hole the liquid flows
from the reservoir to the auxiliary receptacle while air enters through the upper
hole, the flow ceases when the liquid in the auxiliary receptacle reaches the level of
the upper or air hole in the reservoir.
In order that my invention may be well understood and carried into practice, I
will now proceed to describe the same with reference to the accompanying drawings
in which similar letters indicate corresponding parts throughout.
Figure 1 shews a view of my improved can, in vertical section. The dotted line
shews that the holes G, H, are below the level of the funnel shaped bottom, so that
the liquid in the reservoir E cannot flow into the receptacle F until the vessel is
upright. Figure 2 is an inverted plan of Figure 1, and Figures 3 and 4 are respec-
tively elevation and section of a modification of my invention.
The bottom A of the vessel is made of a conical curved or arched form, as shewn
in Figure 1 to act as a funnel so that when the vessel is upright, the liquid flows into
the auxiliary receptacle F in the bottom of the vessel. The opening B in the
bottom of the vessel is internally screw threaded to take the flanged screw stopper C
which with the washer D closes the opening B and prevents leakage therefrom when

page_text: the vessel is upright. The auxiliary receptacle F is constructed upon or affixed to the
bottom of the side of the reservoir E and either outside thereof, as shewn in Figures 3
and 4, or inside, as shewn in Figure 1.
Two small holes G and H are made in the side of the receptacle F one above the
other of equal size and form the communicating channels or passages between the
reservoir E and the receptacle F.
There is a third hole shewn in the Figures at K which serves for the admission of
air to the receptacle F as the liquid flows therefrom. The upper air hole G is below
the level of the water, which when the reservoir is replenished reaches to the bottom
of the screw opening, at the apex of the conical base, as indicated by the dotted line
in Figure 1.
To fill the reservoir E the vessel is inverted and the liquid poured through the
opening B in the bottom A of the vessel. When the liquid rises to the top of
the screw opening, the stopper C with its washer D is screwed into position, and
the vessel placed upright. The liquid then flows through the bottom hole H into the
receptacle F, air meanwhile entering through the upper hole G and bubbling up
through the liquid in the reservoir, until the liquid in the receptacle F reaches the
level of the air hole G when the air being entirely excluded from the interior of the
vessel the liquid ceases to flow. Thus the liquid which the receptacle will receive is
always a definite quantity, the amount depending on the distance between the
holes G and H, and upon the capacity of the receptacle F. The liquid in the
receptacle F may now be poured off as required.
It is of some importance that the vessel when it is required to discharge its
contents, should in doing this be raised quickly to a horizontal position, as the outflow
from the containing vessel is then immediately checked by the cohesion of the liquid
in the small openings aided by atmospheric pressure. It will be seen that the vessel
combines cheapness of manufacture with simplicity and efficiency of action, and that it
will remedy waste of the liquid.
In the drawings, I have shewn the invention constructed in the form of a can, but
it is obvious that it may be made of other forms.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is :-
The construction of a can or other vessel with reservoir and auxiliary receptacle
communicating with each other as above described, designed to be replenished from
the bottom thereof, substantially as and for the purpose hereinbefore set forth and
illustrated in the accompanying drawings.
