Eccentric Revolving Fermentation-chamber for Cocoa Beans,
CHARLES RISK, Civil Engineer, Grenada, West Indies, do hereby declare the
nature of this invention to be as follows:-
An eccentric, revolving, fermentation-chamber, for the treatment of cocoa beans
in there raw state:-The chamber revolves, and is supported on columns, and
hung on pivots on revolving shafts, revolved by hand gear:-it is set at angles to
impart certain motions to the cocoa beans during the fermentation process.
The chamber is made of wood plank, and is made oblong having on each end,
a cast iron frame hung on centres placed diagonally, these centres work on iron
columns. At one end, and fixed on iron column is toothed gear which is to turn
the box; the box is revolved by manual labour.

I, CHARLES RISK, Civil Engineer, Grenada, West Indies, 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 an eccentric revolving fermentation-chamber for the
treatment of cocoa beans in their raw state. The chamber which is set at angles
to impart certain motions to the cocoa beans during the fermentation process,
revolves and is supported on columns to which it is, hung by pivots on revolving
shafts operated by hand gear.
But in order that my said invention may be readily understood and easily
carried into effect I will proceed to describe the same with reference to the
accompanying drawings in which
Fig. 1 is an elevation, partly in section, and
Fig. 2 an end view of the fermentation-chamber.
Referring to the said drawings, the chamber A is made of wood plank and
oblong in form having at each end a cast iron frame B formed with two brackets
or snugs C which are pivotally secured to a moving piece I by pinching screws d.
The said moving piece D is also pivotally secured by similar pinching screws
within a forked bracket E which is keyed upon the shaft F. The pivots are.
placed at diagonally opposite corners of the chamber and their universal joint
construction permits the chamber to be freely and eccentrically revolved through
the intervention of the spur wheel and pinion G, G¹, which latter is rotated by the
hand crank H.

page_text: The chamber A is provided with a lid J hinged at j and retained in its closed
position by two snibs or hasps j. The drawing only shows one hinge, the other
being removed for the purpose of shewing the interior of the chamber.
k
The inside of the chamber is provided with a central wooden bar K to which are
attached tapered pieces arranged at an angle therewith whereby the requisite
displacement is given to the beans during the revolving of the chamber.
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 eccentric revolving fermentation-chamber for the treatment of cocoa beans,
constructed, arranged and operating substantially in the manner as herein-
before described and shewn in the accompanying drawings.
