PROVISIONAL SPECIFICATION left by the said Melchior Nolden at the
Office of the Commissioners of Patents, with his Petition, on the
19th April 1870.
I, MELCHIOR NOLDEN, of Francfort-on-the-Main, in the Kingdom of
Prussia, do hereby declare the nature of the said Invention for "AN
APPARATUS FOR THE THREEFOLD PURPOSE OF CURING OR DRYING MEALY AND GRAINY.
STUFFS, HEATING, COOLING, AND MIXING FLUID SUBSTANCES, AND CONDENSING
GASEOUS ONES," to be as follows:-
I employ a square or oblong metal box, having at the bottom an
opening which can be covered by a plate, and at the top a semicircular
cover, and form at the ends of the box and cover bearings for carrying
a hollow shaft, to which is fixed a driving pulley outside the box and
two perforated discs with internal spiral ribs, and the peripheries of the
discs are fitted to circular rims in the cover and box. To the spiral ribs
are fixed strips of tinned or other metal plate so as to form a spiral

page_text: cylinder from the exterior to the hollow shaft, to which it is also fixed,
and in the box there are four compartments communicating with each
other by holes in the circular rims. At one end of the box there is an
open chamber divided into two compartments, in each of which there
are hollow scooping pipes fixed to that end of the hollow shaft and
leading into its interior, and the box and compartments are provided
with the necessary ingress and egress pipes, and the interior of the
hollow shaft is made parallel or conical as required. When grain, seeds,
malt, meal, or other analagous substances require to be dried or cured
they are passed into one of the open compartments, and revolving motion
is given to the hollow shaft, scooping pipes, and spiral cylinder, the
scooping pipes leading the substance into the interior of the hollow shaft
and from thence through passages to the innermost. surface of the spiral
cylinder, which, as it slowly revolves, leads the substance to the bottom
of the box; and during the operation superheated steam or heated air is
allowed. to stream through the perforations of one of the discs into the
spaces of the spiral cylinder and escape through the perforations of the
other disc to an escape pipe, and the substances when dried are removed
through the opening at the bottom of the box. When liquids have to
be heated or cooled they are supplied by a pipe to the before-mentioned
compartment, from whence they are scooped and led into the interior of
the hollow shaft and spiral cylinder to an escape pipe, and when they
are flowing steam or cold air is circulated through the machine. When
two liquids have to be mixed both compartments of the open chamber
are used, one liquid being supplied to the hollow shaft and spiral
cylinder by one set of scooping pipes and the other liquid by the other
set. When gases or vapours are required to be condensed they are led
into the spiral cylinder and cold water is introduced by means of the
scooping pipes, and, when required, there is an additional perforated disc
and a second spiral cylinder.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Melchior Nolden in the Great Seal Patent Office
on the 19th October 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MELCHOIR
NOLDEN, of Francfort-on-the-Main, in the Kingdom of Prussia, send
greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of April, in the year of
our Lord One thousand eight hundred and seventy, in the thirty-third
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Melchoir Nolden, Her special licence that I,
the said Melchoir Nolden, my executors, administrators, and assigns, or
such others as I, the said Melchoir Nolden, my executors, adminis-
trators, and assigns, should at any time agree with, and no others, from
time to time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for "AN APPARATUS FOR THE THREEFOLD
PURPOSE OF CURING OR DRYING MEALY AND GRAINY STUFFS, HEATING, COOLING,
AND MIXING FLUID SUBSTANCES, AND CONDENSING GASEOUS ONES," upon the
condition (amongst others) that I, the said Melchoir Nolden, my
executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same
was to be performed, and cause the same to be filed in the Great Seal
Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said Melchoir Nolden, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement thereof, reference being had to the Figures on the
accompanying two Sheets of Drawings, and to the letters of reference
marked thereon (that is to say) :-
:-
Fig. 1, Sheet 1, is a longitudinal section, and Fig. 2, a longitudinal
elevation of one arrangement of my improved machinery; Fig. 3, a
plan of the same with part removed.
Fig. 4, Sheet 2, an enlarged transverse section at the centre of the
machine, marked x, y.
Fig. 5, an elevation of one end of the machine, and Figs. 6, 7, and 8,
sections of parts detached.
The machinery consists of a square or oblong metal box B, having at
the bottom an opening which can be covered by a plate or cover t and
at the top a semicircular cover A, there being at the ends of the box
and cover bearings for carrying a hollow shaft b, to which is fixed a

page_text: driving pulley a outside the box, and two perforated dics c, c¹ with
internal spiral ribs y, formed like a helix, and to the spiral ribs are fixed
strips of tinned or other metal, so as to form a spiral or helical cylinder
from the exterior to the hollow shaft b. The peripheries of the discs are:
encircled by partition q, r, in the cover and box cut like a socket, which
united with the partition S, Figs. 4 & 8, divide. the interior of the
box into four compartments marked III., IV., V., and VI., communi-
cating with each other by three holes i, k, l, in the partitions q, r,
between which the cover t is placed. At one end of the box there is an
open chamber divided by a partition into two compartments, I. and II.,
and to that end of the hollow shaft b are fixed two bosses, one carrying
-three-scooping-pipes_d, which enter the compartment I., and the other
three scooping pipes e entering the compartment II., the interiors of
the pipes leading into the hollow part of the shaft b, and the short pipes
f, g, h, m, n, o, p, form the various ingress and exit pipes. With sub-
stances, which in consequence of their consistency are slow in their
passage, the. hollow part of the shaft b is conical, as shewn in Fig. 7,
but in other cases it is parallel, as in Fig. 1. When grain, seeds, malt,
meal, or other analogous substances are to be dried or cured they are
put in the compartment I. of the open chamber, and revolving motion
given to the hollow shaft, scooping pipes, and spiral or helical cylinder,
the scooping pipes d leading the grain or other substance into the hollow
in the shaft, from which it passes through slots or passages to the inner-.
most surface of the cylinder and onwards over the slowly revolving
spirals until it reaches the bottom of the box. During these operations.
superheated steam or heated air is allowed to stream through the pipeƒ
into the compartment IV., through the perforations in the first disc c to
the grain in the spiral spaces, and onwards through the perforations in the
second disc c¹ into the compartment VI., from whence it escapes through
the pipe g, and the substances when dried are removed through the
opening at the bottom of the box. When liquids have to be heated or
cooled they are supplied by the pipe m to the compartment I of the open
chamber, and are introduced by the scooping pipes d, d, d, into the interior
of the hollow shaft and spiral cylinder, and whilst the liquids are flowing
through the spiral passages steam or cold air is let in by the pipe ƒ to
heat or cool them as required. When the liquid has arrived at the
bottom of the apparatus it will flow out of the compartment III.
through the hole i; Fig. 5, into the compartment IV., then through
the hole into the compartment V., to pass through the hole into

page_text: the compartment VI., from which it is discharged through the pipe h
out of the apparatus. When two liquids have to be mixed both
compartments of the open chamber have to be used, one liquid
entering the compartment I. by the pipe m and the other liquid the
compartment II. by the pipe n, from whence they are carried on by the
scooping pipes d, d, d, and e, e, e, into the interior of the apparatus, and
then flow off in the mixed state, as before described for a single liquid.
When gases or vapours are required to be condensed they are led into
the apparatus by the pipe f, and the volume of cold water requisite for
condensing is introduced by means of the scooping pipes, the exit pipe q
being closed, and the whole of the interior used for condensing.
In the event of the condensation of gaseous substances becoming
difficult I employ an extended apparatus formed by an additional
perforated disc and a second spiral cylinder enveloped in suitable boxes.
or casing.
Having now described the nature of my said Invention, and the
manner in which the same is to be carried into effect, what I claim and
desire to be secured to me by Letters Patent is, the Invention for "An
Apparatus for the Threefold Purpose of Curing or Drying Mealy and
Grainy Stuffs, Heating, Cooling, and Mixing Fluid Substances, and
Condensing Gaseous Ones," substantially as herein described and as
shown on accompanying Drawings, or any mere modification thereof.
In witness whereof, I, the said Melchoir Nolden, have hereunto
set my hand and seal, this Sixteenth day of September, in the
year of our Lord One thousand eight hundred and seventy.
