Mechanician.
1, EDMUND EDWARDS, of the firm of Edwards and Co., Patent Agents and
Engineers, of 35, Southampton Buildings, Chancery Lane, in the County of
Middlesex, do hereby declare the nature of this invention to be as follows:-
The apparatus which forms the subject of the present invention is intended to
receive and treat ordinary paste, which has been boiled for about 10 to 15 minutes
either in the apparatus itself or in another suitable vessel, in order that it may be
cooled as slowly as possible, and rendered smooth and uniform in quality by
constant agitation, whilst it is also kept sufficiently fluid, and fermentation is
prevented, great economy in the fuel used being effected, and the paste being
smooth and more easily worked than has ordinarily heretofore been the case.
In a wooden tub or vessel is fitted a second vessel entirely or partly of metal,
which holds the paste. The space between the two vessels is filled with a material
such as cork a non-conductor of heat in order that the contents of the inner vessel
may cool as slowly as possible.
An agitator, consisting of a central vertical spindle having an adjustable radial
arm above and below between which a sufficient number of chains are stretched,
is carried by the bottom and the cover of the inner vessel. The spindle can be
made to revolve by any suitable power so as to keep the paste constantly agitated
when cooling.
The cover is provided with handles by which it can be removed and replaced, and
also with bearings for the spindle and for a horizontal skaft which drives the latter
by bevilled toothed wheels.
The two vessels are properly stayed together where necessary.
A discharge pipe from the bottom of the inner vessel allows the liquid paste to be
withdrawn as required.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Preparing Paste.
A communication to me from JOSEPH EISENRING, of Lommenschwil, Switzerland,
Mechanician.
1, EDMUND EDWARDS, of the firm of Edwards and Co., Patent Agents and
Engineers, of 35, Southampton Buildings, Chancery Lane, in the County of
Middlesex, 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 and accompanying drawing that is to say :--
The apparatus which forms the subject of the present invention is intended to
receive and treat ordinary paste, which has been boiled for about 10 to 15 minutes
cither in the apparatus itself or in another suitable vessel, in order that it may be
cooled as slowly as possible, and rendered smooth and uniform in quality by
constant agitation, whilst it is also kept sufficiently fluid, and fermentation is

page_text: prevented, great economy in the fuel used being effected, and the paste being
smooth and more easily worked than has heretofore ordinarily been the case.
In the accompanying drawing which is in illustration of the invention,
Figure 1 is an elevation of the apparatus, partly broken away to shew the interior
mechanism, and
Figure 2 is a plan.
In a wooden tub or vessel A. is fitted a second vessel C of metal or of wood lined
with copper, which holds the paste. The space B between the two vessels A
and C is filled with a material such as cork a bad conductor of heat in order that
the contents of the inner vessel.C may cool as slowly as possible.
An agitator, consisting of a central vertical spindle E having an adjustable
radial arm D, D, above and below, between which a sufficient number of chains
are stretched is carried by the bottom and the cover of the inner vessel C. The
spindle can be made to revolve by any suitable power so as to keep the paste
constantly agitated when cooling.
The cover C¹ of the vessel C is provided with handles by which it can be
removed and replaced to charge the latter vessel, the other parts A, B, and C,
being fixed together by screws, and the cover being also provided with bear-
ings F, F, for the spindle E and for a horizontal shaft E' which drives the latter
by bevilled toothed wheels, and pullies G.
A discharge pipe H from the bottom of the inner vessel allows the liquid paste
to be withdrawn as required.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed declare that what I
claim is
An apparatus for the preparation of paste, consisting of two vessels A and C,
arranged concentrically one inside the other, the space between them being filled
with a bad conductor of heat, the inner vessel C which contains the paste being
provided with an agitator D, the parts of which are connected together by
vertical chains, and which is made to revolve by means of the spindles E, E,
bevilled toothed wheels, and pullies G, substantially as described and shewn.
