I, THOMAS BAKER RANDALL, of the Firm of Randall Brothers,
Merchants, of Lime Street, in the City of London, do hereby declare
the nature of the said Invention for "AN IMPROVED APPARATUS FOR POURING
OB DRAWING OIL OR OTHER LIQUIDS FROM CASKS, CANS, BOTTLES, OR OTHER
VESSELS," to be as follows:-
My Invention relates to a novel and simple apparatus designed for
application to casks or barrels, metal cans, bottles, jars, and other
vessels containing oil or other liquids to facilitate the pouring out or
drawing of such liquid, and to graduate and control the quantity of
liquid transferred from one vessel to another, and prevent undue
disturbance or agitation of the said liquid in pouring out or drawing off
the same.
The said Invention consists, first, in the combination with a cork.

page_text: another tube for the admission of air into the vessel above the liquid
therein, when the same is tilted for pouring out the said liquid.
The said apparatus is very advantageous for transferring petroleum
and other oil from large cans into small cans or oilers, or from one vessel
to another of any kind and for any purpose.
The said Invention is preferably carried into practise as follows :—
I take an ordinary cork or bung or a stopper formed of metal or other
suitable substance, and pass through the same two tubes of metal, glass,
or other material. One of these tubes is for the exit or discharge of the
liquid from the can or other vessel, the other for the entrance of air into
the same, and I term the former the liquid tube and the other the air
tube. The liquid tube may be made either straight or curved as
required. Its outlet end should be of convenient shape to form a spout,
and should be larger at the part near the cork than at its extremity.
The air tube must have its inner portion so curved or shaped that when the
stopper is inserted in the can or other vessel, and the latter is tilted for
pouring out the liquid therefrom, the extremity of the said tube will be
above the surface of the liquid, and the air entering through the said
tube will occupy the space in the vessel above the liquid. This air tube
should be of such form and dimensions as to admit the air freely to fill
up the vacuum left by the displacement of the fluid in the vessel.
The said tubes and stopper may be finished and ornamented in any
desired manner.
If I use a metal stopper I make it nearly of the shape of an ordinary
cork, and pass the tubes through the same as above described. And I
provide the said stopper with a closely fitting outer covering of india-
rubber, cork, or any other suitable material, which allows the said
stopper to be easily fitted and made tight in the neck or mouth of any
vessel.
In some instances I provido the top of the pipes with a cap to close
them when not in use to prevent evaporation.
My Invention also comprises a cock or tap constructed to allow air to
pass into the vessel or cask, to which the said cock is applied to avoid
the disturbance of the liquid, which would be occasioned by allowing
the air to enter below the surface of the liquid, thereby causing bubbles.
For this purpose I add to an ordinary tap or cock an air tube, which is

page_text: passed through and forms part of the tap and is controlled by the plug
thereof; this plug has two chambers, an air chamber and a fluid
chamber, which are opened and closed simultaneously. The interior
part of the air tube is extended beyound the tap and turned upward, its
extremity being at or above the surface of the liquid in the interior of
the said cask or vessel.
