I, PETER JENSEN Fel. Inst. P.A. of 77 Chancery Lane in the County of
Middlesex do hereby declare the nature of this invention a communication to me
from abroad by M. C. P. Barbe, Managing Director of the Company "Naamlooze
Vennootschap Wester-Suikerraffinadery" Amsterdam, Holland, Sugar Refiners and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
This invention has reference to the construction of the partition wedges and
centrifugal drum or hydro extractor for production of refined sugar described in
the Specification of my Patent dated 27th August 1885 N° 10172. According to
this present invention these wedges are simplified in construction and so as to
serve also for lifting out of the centriful hydro extractor the formed cakes or slabs
of sugar.
Figure 1 of the accompanying drawings is a sectional elevation of part of the
centrifugal hydro extractor and Figure 2 a part plan partly in section. Figure 3
is a side view of a wedge, Figure 4 an end view and Figure 5 a plan.
For the purpose of this invention the partition wedges F are made with a lateral
bottom flange 8 the width of which is about equal to the thickness of the slab of
sugar to be produced in the hydro-extractor; each wedge F is provided with a
handle t at the top or equivalent means for raising it by; there is a projecting
nose u at the top of the wedge, and the rim of the drum is formed with corre-
sponding equidistant notches v.
: When these wedges F are put into the centrifugal hydro-extractor as shewn in
Figures 1 and 2 the noses u enter the notches in the rim of the drum. The
wedges F rest directly on the bottom of the drum, and are kept the right distance
apart partly by their lateral bottom flanges 8 and partly by their upper noses u
fitting in the notches v. In this manner rectangular parallel spaces W are formed
into which the filling mass (masse cuite) is put. When the cakes or slabs of sugar

page_text: have been produced in the manner described in the Specification of the aforesaid
Patent No 10172/"; all that is required for removing the slabs of sugar is to draw
up the wedges F taking hold of them by the handles t whereby the slabs which
rest on their bottom flanges u are simultaneously raised out of the drum.
The advantage of this arrangement is that fewer slabs of sugar are broken than
when the wedges are drawn out of the drum separately from the slabs, and the
whole operation of withdrawing the wedges and cakes is expedited.
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 as the invention communicated to me is :-
In centrifugal hydro-extractors for producing refined sugar in slabs the appli-
cation of partition wedges F which are provided with a lateral bottom flange 8,
with an upper handle t or equivalent means and with a nose u or guide at top
fitting in a corresponding notch in the drum for the purpose of withdrawing the
formed sugar slabs from the drum simultaneously with the wedges.
