LETTERS PATENT to Frank Wirth, of the Firm of Wirth and Company,
Patent Agency, of Frankfort-on-the-Maine, in the Empire of
Germany, for the Invention of "IMPROVEMENTS IN THE PROCESS OF
CLAYING OR REFINING LOAVES OF SUGAR AND IN THE APPARATUS OR
APPLIANCES EMPLOYED THEREIN."-A communication from Eugen
Langen, a person residing at Cologne, on the Rhine, in the Empire
of Germany.
COMPLETE SPECIFICATION filed by the said Frank Wirth at the Office
of the Commissioners of Patents, with his Petition-and Declaration,
on the 25th July 1874, pursuant to the 9th Section of the Patent
Law Amendment Act, 1852.
TO-ALL-TO WHOM THESE: PRESENTS: SHALL COME, I, FRÄNK

page_text: WHEREAS I am in possession of an Invention for "IMPROVEMENTS
IN THE PROCESS OF ⚫ CLAYING' OR REFINING LOAVES OF SUGAR AND IN THE
APPARATUS OR APPLIANCES EMPLOYED THEREIN," and have petitioned Her
Majesty to grant unto me, my exccutors, administrators, and assigns,
Her Royal Letters Patent for the same, and have made solemn Declara- 5
tion that it has been communicated to me by Eugen Langen, a person
residing at Cologne, on the Rhine, in the Empire of Germany.
NOW KNOW YE, that I, the said Frank Wirth, do hereby declare that
the following Complete Specification, under my hand and scal, fully
describes and ascertains the nature of the said Invention, and in what 1
manner the same is to be performed, in and by the following state-
ment:-
The object of this Invention is to perform the operation known as
"claying" loaves of sugar by forcing the "claying" or refining liquid
from below upwards through the sugar by means of hydrostatic or other 1
suitable and efficient pressure; also the arrangement of suitable
appliances or apparatus for speedily and efficiently performing such
operations.
In order that the said Invention may be more easily and more fully
understood and be more readily performed, I now proceed to explain the 2
same with the aid of the accompanying Drawing which forms part of
this Specification, reference being made thereto by the numerals and
letters marked thercon, and which reference applics to each Figure of
the said Drawing where the same index numerals and letters appear.
Figuro 1 is a horizontal plan of my improved apparatus shewing the 2
arrangement of the moulds and the pipes through which the claying
liquor passes; Figure 2 is a longitudinal section of the same on the line
A, B, Figure 1, showing the said moulds and the troughs or trays under
them; Figure 3 is a transverse section thereof on the line C, D, Figure 1,
and the lino E, F, Figure 2, showing the arrangement for fixing the 30
covers to the moulds and the moulds to tho tablo; also the arrangement
for holding the said covers on the moulds during the process of
claying.
The table A, B, C, D, is of cast iron, and is formed with the requisito
holes or onenings in the top thereof: at the rootononlar onanine

top and bottom; thoir upper ends when in use are covered with a metal
cover or cap c', under which cover is placed an elastic plate or sheet of
india-rubber c³, covering the whole top. In and through the cover c¹
O and the said clastic plate a hole h is cut or formed. The moulds c are
placed in pairs, one directly opposite the other, for the purpose of
pressing the said moulds against the table by the two-armed cross beam d
resting on a projection c³ formed on the cover c', which cross beam dis
operated by the screw d¹ and the lever d³, thus completely securing the
5 moulds c to the table and the covers c' on the said moulds. The several
troughs a in each line are connected or united by the pipes c, and the
pipes e of both lines are united at one end by the bent pipe e¹, the pipes e
being effectually closed at their opposite ends e. To the pipe c' is
attached the supply pipo f, by which the claying liquid is conveyed to
0 the apparatus. This supply is regulated by the cock f.

When the moulds containing sugar loaves aro thus. fixed by turning
the cock f¹ the claying liquid is forced by hydraulic or other pressure
through the pipes e¹ and e to the troughs a, and thenco into the sugar in
the moulds c from the bottom upwards.
In order to modify the inrush of the stream of claying liquid, and
thus prevent injury being done to the sugar thereby, I placo a perforated
plate or a grating in the troughs a immediately under the sugar loaf
'so as to diminish the shock of the suddenly entering liquid. The claying
liquid will rise more or less rapidly, according to the degree of pressuro
O applied thereto, and force away the "green syrup" and the air contained
in the sugar, which make their escape through the holes h. The covers o'
are formed with a rim or raised edge or margin m, and on one side of
the covers a spout or gutter n is fixed, by which the syrup forced out of
the sugar on to the covers c is conducted to the gutter i, by which it is
35 conveyed to a receiver or reservoir at the end of the table. The gutters k,
one on each side of the table, are provided to receive any claying liquid
which may escapo over the edges of the troughs a.

loaves simultaneously and speedily, substantially as and for the purposes
herein described and shewn in the Drawing.
In witness whereof, I, the said Frank Wirth, have hereunto set my
hand and seal, this Second day of July, in the year of our Lord
One thousand eight hundred and seventy-four.
