A New or Improved Apparatus for Separating Bodies of Different
Specific Gravity when Immersed in a Liquid.
I CHARLES STEPHEN MEACHAM of Pettridge Bower Mount Road Maidstone
in the County of Kent, Brewer, do hereby declare the nature of this invention to
be as follows:-
The object of my invention is to enable an operator to readily & conveniently
obtain in a separate state for examination bodies which have a different specific
gravity or floating power in a liquid, as for instance a sample of malt thrown into
water in which case some float on the surface whilst others sink.
The apparatus consists of.
(A) An outside vessel constructed of any suitable material and shape; prefer
ably a cylindrical or beaker shaped vessel made of glass, which is partly filled with
water when in use.
(B) A perforated separator preferably of funnel shape, viz.; that of an inverted
cone, constructed of any metal or other suitable material with an orifice at the
bottom or apex to allow the sinking corns or other bodies to subside through.
This separator is provided with a stirring rod which by means of an enlargement
at one end forms a combined stirring rod & plug, for closing the opening in
bottom of separator as required.
(C) A receiving tray of metal or other suitable material, preferably constructed
of wire gauze: this tray is held in position underneath the orifice in separator by
a frame attached to separator.
The method of procedure is as follows, the separation of the sinking corns in
a sample of malt being taken as an example.
The vessel "A" is partly filled with water and the separator "B" with its
accompanying receiving tray is immersed therein.
A given number of grains of the malt to be examined is thrown into the water in
the separator & stirred with the plug-rod.
The sinking corns are allowed to subside through the orifice in bottom of
separator and are caught and retained by receiving tray. The plug is now inserted
and the whole-separator and receiving tray-lifted bodily out of the water.
The two lots of grain are thus obtained separated; those that have floated being
retained by the separator and those that have sunk being in the receiving tray
ready for examination.
The above apparatus is applicable to the separation of any bodies having a
different specific gravity or floating power either in water or any other liquid.

I CHARLES STEPHEN MEACHAM of Pettridge, Bower Mount Road Maidstone
in the County of Kent Brewer 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 enable an operator to readily & conveniently
obtain in a separate state for examination, bodies which have a different specific
gravity, or floating power in a liquid, as for instance a sample of malt thrown into
water, in which case some float on the surface whilst others sink.
The apparatus consists of.-
(A) An outside vessel constructed of any suitable material and shape, preferably
a cylindrical or beaker shaped vessel made of glass, which is partly filled with
water when in use.
(B) A perforated separator, preferably of funnel shape, viz.; that of an inverted
cone constructed of any metal or other suitable material with an orifice at the
bottom or apex to allow the sinking corns or other bodies to subside through.
This separator is provided with a stirring rod (D) which by means of an
enlargement at one end forms a combined stirring rod and plug for closing the
opening in bottom of separator as required.
(C) A receiving tray of metal or other suitable material, preferably constructed
of perforated metal, or of wire gauze. This tray is held in position underneath the
orifice in "separator" by a frame (E) attached to the feet of the "separator."
The method of procedure is as follows,-(the separation of the sinking corns in a
sample of malt being taken as an example).
The vessel (A) is partly filled with water, and the separator B, with its
accompanying receiving tray C, placed in position on the frame E, is immersed
therein.
A given number of grains of the malt to be examined is thrown into the water
in the separator and stirred with the plug-rod.
The sinking corns are allowed to subside through the orifice in bottom of
separator, and are caught and retained by the receiving tray. The plug is now
inserted and the whole-separator and receiving tray-lifted bodily out of the
water. The two lots of grain are thus obtained separated; those that have floated
being retained by the separator and those that have sunk being in the receiving
tray, ready for examination.
The above apparatus is applicable to the separation of any bodies having a
different specific gravity or floating power either in water or in any other liquid.
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.-
A rapid, convenient and effective method of separating (in such a manner as to
be readily accessible for separate examination) bodies of different specific gravity
as fully described above.
