Apparatus for Agitating or Mixing Liquids, Washing the Interiors
of Casks and the like, and for other analogous purposes.
We, JOHN BRADBURY, of Murray Street, Hoxton, and CEMER THOMAS
COLEBROOK, of Union Square, Islington, both in the County of London,
Engineers, do hereby declare the nature of the said invention to be as follows:
This invention relates to improved apparatus for agitating or mixing. liquids,
washing the interiors of casks and other vessels especially those. having only a
small opening to the inside such as the bung hole of a barrel, and for other
analogous purposes.
'
The invention consists in so combining a series of levers and connecting links, a
carrying bar and an actuating spindle, as to form an expanding framework, which,
when closed, may be readily passed through the bung-hole of a barrel..or the
opening to the interior of any other vessel, and then, upon the actuating spindle
being turned in one direction, will expand within the barrel or other vessel to any
desired extent within its limit, and upon the actuating spindle and carrying bar
being then together turned (either by hand or by suitable motive power) will
revolve therewith about the carrying bar as a centre, and will cause any liquid or
liquids within the vessel to be thoroughly agitated or mixed, and so as thoroughly
to wash the interior of the vessel if applied to such a nse. On reversing the
turning of the actuating spindle, the framework will be caused. to collapse, and
may then be readily withdrawn from the interior through the bung-hole-or-other
opening in the vessel.
According to one modification, such apparatus may be constructed with a
carrying bar (of suitable dimensions) formed with an internally screwed tubular
end slotted to receive a sliding boss fitted with a projecting pin or .pins for
actuating the expanding levers. Through the said tubular end is passed an
actuating spindle which screws into its interior and is connected to the said sliding
boss. On one or both sides of the carrying bar are arranged a suitable number of
lever arms connected at their free ends by links, and those adjacent to the said
sliding boss being slotted for engagement with the pin or pins projecting therefrom.
By such means, on turning the spindle in the one direction within the tubular end
of the carrying bar by a handle or other convenient means applied thereto (the
carrying bar being prevented from rotating) the boss, connected levers and links
will be so actuated as to cause the framework formed by the lever arms and links
to expand to the desired extent, and on the motion of the spindle being reversed
(while the carrying bar is still prevented from rotating) the connected links and
levers will be caused to contract and close together again, so as to admit of the
apparatus being readily withdrawn from inside the cask, barrel or other vessel
through the opening thereinto. The tubular end of the carrying bar is provided
with projections by which it may be prevented from turning with the spindle while
the framework is being expanded or contracted. It is or may also be provided
with a steadying guide, bush or cone, capable of being adjusted on the said tubular
end, to permit of the apparatus being used for vessels of different depths and of the
expanded apparatus being rotated within the barrel or container.
According to another modification, a suitably arranged spring or springs may be
used in lieu of the screw and internal spindle.

Apparatus for Agitating.or Mixing Liquids, Washing the Interiors
of Casks and the like, and for other analogous purposes.
We, JOHN BRADBURY, of Murray Street, 'Hoxton, and CEMER THOMAS
COLEBROOK, of Union Square, Islington, both in the County of London,
Engineers, do hereby declare the nature of the said 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 improved apparatus for agitating or mixing liquids,
washing the interiors of casks and other vessels especially those having only a
small opening to the inside such as the thung-hole of a barrel, and for other
analogous purposeš.
The invention consists in so combining a series of levers and connecting links, a
carrying bar and actuating spindle, as to form-an-expanding framework, which,
when closed, may be readily passed through the bung-hole of a barrel or the
opening to the interior of any other vessel, and then, upon the actuating spindle
'being turned in one direction, will expand within the barrel or other vessel to any
desired extent within its limits, and upon the actuating spindle and carrying bar
being then together turned (either by hand or by suitable motive power) will
revolve therewith about the carrying bar as a centre; and will cause any liquid.or
liquids within the vessel to be thoroughly agitated or mixed, and so as thoroughly
to wash the interior of the vessel if-applied-to such a use. On reversing the
turbing of the actuating spindle the framework will be caused to collapse, and
may then be readily withdrawn from the interior through the bung-hole or other
opening in the vessel.
On the accompanying drawings,
Figure 1 represents an elevation, partly in section of the device in condition for
insertion through the bung-hole of a barrel or the like.
Figure-2 represents a like view of the device in its'expanded condition.
3, represents the carrying-bar which is formed with an internally screwed
tubular part 4, and is slotted-at-5,-to-receive-a-sliding boss 16; fitted with a
projecting pin or pins 7, 'for actuating the expanding framework of linked
levers 8, 9.
Through the tubular part 4, is passed an actuating spindle 10, which-screws into
its interior and is connected to the sliding boss 6.
On one or both sides of the carrying bar are arranged a suitable number of
lever-arms'8, connected at their free ends by links 9, those adjacent to the sliding
boss' 6, being slotted as at 11, for engagement with the pin or pins 7, projecting
therefrom.
The tubular part 4, of the carrying-bar is provided with projections 12, by which
it may be prevented from turning with the spindle while the framework is being
'expanded 'or 'contracted. It is or may also be provided with a steadying guide,
bush or cone-13,-loose-or-capable of being adjusted on the said tubular part of the
carrying bar to permit of the device being used for vessels of different depths and
of the expanded apparatus being rotated within the barrel or container.
By such means on turning the spindle 10, in the one direction within the tubular
part 4, of the carrying bar 3, byfa handle 14, or other convenient means applied
thereto, the carrying bar being prevented from rotating by holding the pro-
jections 12, the boss, connected levers and links will be so actuated as to cause the
framework formed by the lever-arms and links to expand to the desired extent, and
on the motion of the spindle being reversed: (while the carrying bar is still pre-
vented from rotating) the connected links and levers will be caused to contract
and close together again, so as to admit of the apparatus being readily withdrawn
from inside the cask; barrel or other vessel through the opening thereinto.

page_text: According to another modification, a coiled spring or springs arranged within the
tubular part 4, may be used in lieu of the screwed spindle for distending the said
framework, which may be closed by hand for inserting the device into the barrel
or by withdrawing the device therefrom and kept closed when required by a
sliding ring.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
In-apparatus for agitating or mixing liquids, washing the interiors of casks and
the like and for other analogous uses, in combination, a series of levers and
connecting links, a carrying bar and actuating spindle arranged so as to co-operate
in the manner herein before described.
