of Oil Cans or of other Receptacles or Vessels.
I, ARCHIBALD HART, of Newtown of Pitcairns, Dunning, in the County of Perth,
North Britain, Minister of the Gospel do hereby declare the nature of this invention
to be as follows:-
This Invention, relates to improvements in facilitating the decanting of Parattin or
other oils from their receptacles or tins for the more especial object of facilitating the
supply of Oil to the Oil Vessels of lamps or stoves.
In applying my improvements to cans having oval shaped mouths I fit two tubes
through a cork or bung which is made to closely fit the mouth of the tin, the one tube
being for the purpose of conducting the oil from the tin to the lamp, the other tube
supplying the necessary air and regulating the same, both tubes are bent to a shape
preferably nearly at right angles with the vertical, the oil supply tube being of this
shape for the purpose of the more conveniently delivering the flow of oil and also for
the purpose of rapidly withdrawing the flow to prevent any dropping of the Oil when the
operation of filling the lamp is completed. The outer extremity of the air supply tube
is at a suitable height above the oil level in the tin so that there may be no escape or
overflow when the oil tin is tilted or inverted when the oil supply is low or at other
times.
For the purpose of securely mounting the tubes through the cork or bung I prefer
to employ a cap of brass, tin or other metal which fits tightly over the top of the cork,
the tubes being passed through holes in the top of the cap and brazed thereto.
In using my improved Appliance, small corks or caps may be used with the outer
ends or mouths of the tubes, or I may form the said mouths with small taps.
With the use of my improved Appliance I am enabled to fill the oil vessels of most
lamps now in use without the necessity of first withdrawing the burner or extinguishing
the light.

I, AROHIBALD HART, of Dean Cottage, Newtown-of-Pitcairns, Dunning, in the
County of Perth, North Britain, Minister of the Gospel, 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 :-
This Invention relates to improvements in facilitating the decanting of liquids, and
has special reference to the decanting of Paraffin and other oils from their receptacles
or tins for the replenishing of lamps, or stoves, and all kinds of oil burning
appliances.
In accordance with my Invention the oil can when once filled, is always ready
for use without any uncorking or uncapping, by the employment in accordance
with my Invention, of decanting tubes fitted through the cork or cap.
In accordance with one form of my Invention as shown in figure 1, I employ
two tubes A, B, fitted through the cork C. The tube B, is the oil supply tube,
and A, the air inlet tube; the tubes are preferably bent right angular, for the
purpose with regard to the oil supply tube, of the more conveniently delivering
the flow of oil and also for the purpose of rapidly withdrawing the flow to prevent
any dropping of the oil when the operation of filling the lamp is completed; the air
supply tube is preferably at a suitable height above the oil level in the tin so that
there may be no escape or overflow when the oil tin is tilted or inverted.
For the purpose of securely mounting the tubes through the cork or bung
I prefer to employ a cap of brass D, tin, or other metal, which is fitted tightly
over the top of the cork, the tubes being passed through the cap and brazed
theroto.
If desired small corks or caps may be used with the outer ends, or mouths of the
tubes, or I may form the said mouths with small taps.
With the use of my improved appliance I am enabled to fill the oil vessels of most
lamps now in use without the necessity of first withdrawing the burner or extinguishing
the light.
Figure 2, of the accompanying Drawings illustrates a modification of my Invention
in which the one tube is fixed at right angles, or approximately so, with the other,
this arrangement is found to facilitate the filling of the oil vessel when the globe is on
the lamp; in this case the oil supply tube E, is bent to a swan neck shape to facilitate
the flowing of the oil; the air supply tube F', is extended to the base of the conical
portion of an ordinary oil can and bent towards the side thereof, this arrangement
being found to prevent any oil entering the tube; this said arrangement of the oil
supply tube is equally applicable to the arrangement shown in figure 1.
In figure 3, of the accompanying Drawings, an arrangement is shown in which the
air supply pipe is not mounted through the cork and thus leaves the outflow oil pipe
free

page_text: As shown in the Drawing the air inlet pipe G, is passed through the top of the
cone of the oil can, the outlet as shown in dotted lines being preferably brought in
proximity with the base of the conical portion; this position being found the most
suitable for preventing any tendency of the oil to enter the said air pipe; it is found
convenient to locate the air inlet round the top handle as shown in the Drawing, but
any other suitable mode of securing the said pipe may be employed, where no such
handle is used. I prefer to employ a small ring between the two handles for the
insertion of the forefinger and when stopping the flow suddenly, the thumb is pressed
on the mouth of the air tube G.
Figure 4, shows an adaptation of my Invention to a watering can for gardening
purposes; the air inlet is shown dotted at J, the communication thereto being effected
by a tube or half tube portion j, the whole top therefore of the can can be covered,
with obvious advantages; the supply of water being offected by uncorking the rose
portion K, the cork or plug &, fitting into the neck portion of the can, or I may
All the can through the air aperture J, direct or by means of a filler.
My said improvements are equally applicable to decanting all kinds of liquids ;
the decanting tubes are serviceable for instance for fitting upon bottles containing
medicines or chemicals where the employment of the ordinary stopper or cork is
found inconvenient.
A similar arrangement to that shown in figure 4, is also serviceable for milk cans.
As a modification of my said improvements, my decanting apparatus may be applied
to fixed oil containers, that is to say, that oil vessels to be filled will be brought to
the container which may be a five or ten gallon Drum, or a twenty or forty gallon
Barrel, my decanter being fitted on to the one end of such containers. Under this
arrangement the Drum stands on its end with the Decanter upon the top end of the
Drum, the drum being filled by pouring the oil in through the decanting aperture or
it may be through the air aperturo, and without the necessity of withdrawing the
Decanter stopper. Or, I may fill the Drum without setting it on end at all, by
pouring in the oil through the air tube, the air tube being made to touch the upper
surface of the barrel.
With the decanting tube made of considerable length, the smallest lamps may be
filled out of the largest oil containers.
In lieu of corks for decanter stoppers, I may employ a brass screw spigot and
socket.
In decanting the contents of a barrel I may form a screw, having one or more
threads, on a ring at the top of the stopper where the stopper is brazed for the tubes,
with flanged edge to the ring and which flange, after the stopper is sent home, fixes
the stopper tightly, if the screw ring works into a screw on brass socket, the outer
end of which (the part seen outside the barrel) alone carries the screw thread or
threads which in this case only requires to have few threads to give the greatest
possible strength to the fixing of the stopper, or bung of decanter. The flanged ring
is movable so that the tubes are kept fixed in a proper position and are kept from
revolving when the stopper is being tightened, but which would not be the case with
ordinary spigots. Or, as a modification the threads may be formed on the brazing
of the bung, in which case no flange is required.
With regard to the form of stopper or bung, I prefer, when the arrangement is
to bring both the oil tube and air tube together, as for a narrow necked vessel,
that the stopper be flattened or oval in section and the neck and the mouth of the
vessel also flattened or oval in section instead of being round, where that can be
done conveniently. This is the only case in which flattened or oval stoppers are
preferable, as by this arrangement there is plenty of room for forming the holes
through the cork and the air is kept so much the more above the oil delivery channel,
which is of importance.
The tubes, in accordance with my Invention, may be of any suitable length, from
inches to perhaps several yards.
In applying my arrangements to a drum for holding oil, which may be repre-
sented by the watering can shown in Figure 4, of the Drawings, the bung shown

page_text: on the outside, (that is to say, partly on the top and partly on the side of the can
as shown in the drawing.) would be kept inside the end or top hoop of the drum,
(that is to say, on the top or end of the drum,) and the direction of the air tube j,
would be reversed, and the said air tube may he of a semicircular shape in section,
the said tube rising to above the level of the oil and having its opening flush with
the outside of the end hoop, and having the necessary screwed cap. Such an
arrangement as this obviates many disadvantages to the large drums with bungs now
in use.
Both the liquid and the air tubes may be made in two, or more parts severally
and may be screwed together, I may also effect the absolute closing of both tubes by
corks or screw caps either inside, or outside end of bung stopper; for instance tlio
bung stopper may be made as a fixture along with the oil drum or barrel.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1st. The general arrangement and construction of apparatus for decanting liquids,
substantially as hereinbefore described, and shown in the accompanying Drawings.
2nd. The arrangement and construction of air inlet, and liquid outlet tubes,
substantially as heroin before described and shown with reference to figures 1, and 2,
of the accompanying Drawings.
3rd. The arrangement and construction of air inlet and liquid outlet tubes in
which the air tube is located apart from the cork or bung substantially as herein-
before described and shown with reference to figure 3, of the accompanying
Drawings.
4th. The arrangement and construction of parts constituting my improved
watering can the same being equally applicable to milk cans, or to cans of a similar
description, or for similar use, substantially as herein before described and shown with
reference to figure 4, of the accompanying Drawings.
5th. The application of said decanting tubes to a stationary drum, or oil reservoir,
or to an oil cask, or barrel substantially as hereinbefore described.
