Apparatus för Treating Latex for the Separation of India Rubber and
Allied Products therefrom.
I, THOMAS CHRISTY, 25, Lime Street, London, E.C., Merchant, do hereby declare
the nature of this invention to be as follows:
-
A machine made in compartments. Into the top chamber A, the latex is
placed and there agitated by a stirrer with the addition of a liquid, water or
alcohol and water by preference. The whole mass is then liberated and it passes
through a lower chamber B, which can be fastened to the chamber A, by hooks
or ordinary attachments. This chamber B, is fitted with a filter which catches
most of the impurities: when the mixture is liberated it falls into a lower
chamber C. This chamber C, is so arranged that water can be poured in at the
side entering low down in the vessel C, causing the rubber to rise: this opera-
tion can be done without necessarily moving the upper chambers A, & B.
separated rubber flows out of an aperture high in the lower chamber C. The
residue and matter other than pure rubber can be drawn off by a tap at the
lowest part of the chamber C.

I, THOMAS CHRISTY, 25, Lime Street, London, E.C., Merchant, 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 a new and useful machine for separating and cleaning
latex. The machine is made in compartments: the latex is placed in the upper
compartment and there agitated by a stirrer, with the addition of water, alcohol
and water, or other suitable liquid. The stirrer forces the latex through a
filter or strainer when the incorporation with water or other liquid has sufficiently
reduced the density of the latex. To facilitate this the arms of the stirrer can
be set so that the top overhangs the lower part in the direction in which the
arm revolves, thus exerting a downward pressure on the liquid when the stirrer

page_text: is in motion. The bottom arm is in contact with the filter or strainer, and it
presses the latex through the strainer as it revolves.
The lower compartment is so arranged that water can be poured in at the side
through a funnel or other suitable construction, the water entering low down in
the compartment,. thus. causing the rubber which has passed through the filter to
rise. The separated rubber flows out of an aperture high in the lower chamber.
The water and matter other than pure rubber can be drawn off by a tap at the
lower part of the compartment.
In the drawings G, represents the top compartment, the dotted lines the
stirrer, H, the filter or strainer which fits into the bottom of the compartment G,
where it is fixed by a metal ring or other suitable contrivance I. The whole
of this upper portion of the machine fits into the lower compartment J, and is
fastened by suitable clamps K. J, represents the lower compartment with
the funnel L, or other suitable arrangement by which water is conveyed to
the lower part of J. It is preferable that the water should enter low down at M...
or thereabouts, so that the rubber rises as the lower chamber is filled with
water, forming a layer on the top of the liquid. N, is an aperture in the com-
partment through which the rubber flows as soon as it has reached the level
of this aperture, which may be so constructed that the hand can be inserted and
any lumps readily removed. To assist the flow a lip O, is placed outside the
aperture N, which reaches from the bottom of the aperture to the top thereof.
The rubber may be collected as it flows over the lip. P, is a tap through which
the superfluous water, residue and waste matter can be drawn off.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner same is performed, I declare that what I claim is;-
1. A machine for separating and cleaning latex by means of a stirrer which
agitates the liquid and forces it through a filter or strainer, thus removing
most of the impurities, and by means of a separate compartment so arranged
that the rubber or gum obtained rises on the surface of the water in the com-
partment and flows out of an aperture substantially as described.
2. The combination of a stirring and filtering machine for cleaning and
separating latex substantially as herein described.
