PROVISIONAL SPECIFICATION.
Improved Apparatus for Drawing off Liquids from Urns or other
Receptacles.
I, HERBERT SUMERLING, of 145 Old Street, London, in the County of
Middlesex, Tinman and Copper Smith, do hereby declare the nature of this
invention to be as follows:-
The object of my invention is to so construct urns or other receptacles for cocoa,
chocolate, or other similar beverages, or other liquids that the contents may be
thoroughly stirred up before drawing off and also be enabled to flow freely through
the tap.
Near the bottom of the urn or other receptacle is fitted a stirrer composed of two
nearly semi-circular perforated plates arranged at right angles to each other, and
provided at one end with a socket, inside of which is fixed in any suitable manner, a
tube which conveys the beverage or other liquid to the tap. The tube passes right
through the tap and is closed' at the end and provided with a handle. A hole is
made in the tube and is arranged so as to come exactly over the opening to the
nose of the tap when the handle is turned on.
By giving the handle a quarter turn the tap will be opened and the half of the
stirrer near the bottom of the urn or other receptacle will be turned upwards and
thoroughly stir up the contents of the urn, or other receptacle, and the other half
of the stirrer will be turned towards the bottom of the urn or other receptacle.
When a sufficient quantity of the beverage or other liquid has been drawn off, a
quarter turn of the handle is given in the opposite direction, which will close the
tap and reverse the position of the stirrer.
It will be understood that the invention may be used in all cases where it is
required to draw off liquids quickly from receptacles of any kind.

COMPLETE SPECIFICATION.
Improved Apparatus for Drawing off Liquids from Urns or other
Receptacles.
I, HERBERT SUMERLING, of 145 Old Street, London, in the County of
Middlesex, Tinman and Copper Smith, 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 my invention is to so construct urns or other receptacles for cocoa,
chocolate, or other similar beverages, or other liquids, that the contents may be
thoroughly stirred up before drawing off and also be enabled to flow freely through
the tap.
Near the bottom of the urn or other receptacle is fitted a stirrer composed of two
approximately semi-circular perforated plates arranged at right angles to each other,

c.
and provided at one end with a socket, inside of which is nxed in any suitable
manner a tube which conveys the beverage or other liquid to the tap. The tube
passes right through the tap and is closed at the end and provided with a handle.
A hole is made in the tube and is ärranged so as to come exactly over the opening
to the nose of the tap when the handle is turned on.
By giving the handle a quarter turn the tap will be opened and the half of the
stirrer near the bottom of the urn or other receptacle will be turned upwards and
thoroughly stir up the contents of the urn or other receptacle, and the other half
of the stirrer will be turned towards the bottom of the urn or other receptacle.
When a sufficient quantity of the beverage or other liquid has been drawn off, a
quarter turn of the handle is given in the opposite direction, which will close the
tap and reverse the position of the stirrer.
It will be understood that the invention may be used in all cases where it.is
required to draw off liquids quickly from receptacles of any kind.
The accompanying drawing illustrates the application of my invention to a hot
water jacketted cocoa or other urn.
Fig. 1 is a vertical section of the urn.
Fig. 2 a sectional plan view of same, and
Fig. 3 an end elevation of the stirrer.
A is the outer case of the urn, B a gas or other burner for heating samė, E the.
inner receptacle (which may be of earthenware or other suitable material) to receive
the cocoa or other liquid, and between which and the outer case A is a space
constituting the water jacket. The whole of above parts may be of ordinary or of
any approved construction.
The tap or cock C for drawing off the liquid from the interior of receptacle E is
secured to the outer casing A, and through it passes a tube D, the outer end of
which is closed and provided with a handle d, while the inner end passes into the
receptacle E. The tube D constitutes the plug of the tap or cock C, and a quarter
turn of such tube either to the left or to the right will open or close such tap or
cock. The tube D passes through the wall of receptacle E in such a way that
while it can turn therein to open and close the tap or cock C, yet the water in the
water jacket will be prevented from passing into receptacle E and mingling with
the liquid to be drawn off. In the drawing the tube D is shown as passing through
a sleeve arranged between the outer case A and the receptacle E, for this
purpose.
A stirrer is employed consisting of two perforated plates F, F¹, preferably of
approximately semi-circular form, which are united so as to form about a right
angle with each other. At one end the stirrer is provided with a socket ƒ, into
which fits the inner end of the tube D, such tube being secured therein in any
suitable manner, such as by a pin f¹ passing through a hole drilled in the socket
and in the end of tube D..
The under side of the stirrer is preferably provided with a segmental rocker G,
which rests on the bottom of the receptacle E, and the edges of the two plates F, F,
of the stirrer are preferably united by a band or strip of metal G₁, serving to
strengthen the stirrer and also as a handle to remove same when required.
The stirrer is secured to the end of tube D. so that when tap or cock C is closed
one of the plates F, F, occupies an approximately horizontal position close to the
bottom of the receptacle E, and when tube D is turned a quarter turn to open the
tap or cock, such plate is moved to a vertical position, while the other plate then
occupies a horizontal position. The reverse movement of the plates F, F¹, of
course occurs when tube D is turned back to close the tap or cock. The segmental
rocker G bearing on the bottom of receptacle E supports the stirrer, which 'rocks
thereon as it turns with the tube D. It will be seen that the plates F, F, of the
stirrer will agitate the liquid contained in the receptacle E, every time the tap or
cock C is opened or closed by turning the tube D.
The stirrer is made sufficiently smaller than the space inside the receptacle E to
enable it to be drawn off the end of tube D, after first unfastening, same, so that the

page_text: stirrer can then be removed by the handle G¹ for cleaning or repairs, or for cleaning
the bottom of receptacle E.
It will be readily understood that the form of the stirrer might be modified
without departing from my invention.
I am aware that cocoa-urns have been formerly proposed in which means have
been provided for stirring up the contents, such means being arranged to be actuated
simultaneously with the turning of the drawing-off cock or tap. I therefore make
no claim to such arrangements generally.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
The improved means for drawing off and agitating the contents of urns or other
receptacles, consisting in a tap or cock secured to the outside of such receptacle,
and through which passes a tube acting as the plug, and to the outer end of which
the operating handle is attached, such tube passing to the interior of the receptacle
and having a stirrer fitted to its inner end, substantially as specified.
