Year: 1863

page_text: LETTERS PATENT to Jean Michel Vanderfeesten, of Brussels, in the
Kingdom of Belgium, Manufacturer, for the Invention of "IMPROVEMENTS
TV ADRADATING FOR HEATING BOILING EVABORATING AND DISTILLING"
Sealed the 21st June 1864, and dated the 29th December 1863.
PROVISIONAL SPECIFICATION left by the said Jean Michel Vanderfeesten
at the Office of the Commissioners of Patents, with his Petition, on
the 29th December 1863..
I, JEAN MICHEL VANDERFEESTEN, of Brussels, in the Kingdom of Belgium,
Manufacturer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN APPARATUS FOR HEATING, BOILING, EVAPORATING, AND DIS-
TILLING," to be as follows:-
My Invention relates to apparatus for heating, boiling, evaporating, and
distilling, whether performed in vacuo or otherwise, and whether for the
manufacture of sugar or for various other purposes.
My apparatus consists of a close or open vessel, in which I fit one or more
horizontal or inclined coils of steam pipes supported on rods or frames with
hollow rollers. The coils are inserted and withdrawn through manholes or
apertures. The ends of the coils are fastened and unfastened by exterior
hollow nuts which work on pipes forming the joints or junctions between the
coils and the steam inlets, and tighten the coils against the sides of the vessel
to the required extent. The coils can be removed from the vessel to be

page_text: cleaned, being for that purpose placed in a separate vessel containing acid
solutions or other material, so that while one coil is being cleaned another can
be placed in the boiling or operating vessel, and the boiling or other operation
need not be interrupted while a coil is undergoing cleansing. The steam joints
may be fitted with nuts.

SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Jean Michel Vanderfeesten in the Great Seal Patent Office
on the 29th June 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JEAN
MICHEL VANDERFEESTEN, of Brussels, in the Kingdom of Belgium, Manu-
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of December, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-seventh year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Jean Michel Vanderfeesten, Her special licence that I, the said Jean
Michel Vanderfeesten, my executors, administrators, and assigns, or such others
as I, the said Jean Michel Vanderfeesten, my executors, administrators, 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
"IMPROVEMENTS IN APPARATUS FOR HEATING, BOILING, EVAPORATING, AND DIS-
TILLING," upon the condition (amongst others) that I, the said Jean Michel
Vanderfeesten, 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 Jean Michel Vanderfeesten, do hereby
declare the nature of the 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 accompanying
Drawings, and to the letters and figures marked thereon, that is to say:-
My' Invention relates to apparatus for heating, boiling, evaporating, and

page_text: .
dusting, whether performed in vacuo or otherwise, and whether Ior the
manufacture of sugar, or for other purposes.
Figure 1 is a front view of an apparatus constructed according to my
Invention; Figure 2 is a back view thereof; Figure 8, vertical longitudinal
section; Figure 4, transverse vertical section on the line I, J, of Figure 8.
A' is a boiler or receiver in which are a number of coils B'; these coils,
instead of forming a single worm or coil rising in curved spirals as is usual,
consist of a number of separate straight coils, as shown, that is, each coil
consists of a certain number of straight or rectilineal horizontal pipes (of
circular or other transverse section) connected by curved junctions. The
coils are arranged side by side; they are not fixtures, but can be removed
from the receiver and replaced therein through openings in the front of the
receiver closed by doors or plates G', G', secured by bolts and nuts. D¹, E,
are horizontal pipes or passages cast on the outside of the receiver A', and
common to all the coils. The pipe D', which communicates with a steam
boiler, is for admitting steam to the coil, and the pipe E' is for drawing off
the waters of condensation therefrom. When the coils are placed in the
receiver their ends are caused to project through the back thereof into the
pipes D', E'; those ends are closed, but they communicate with the pipes
D', E, through lateral openings b. q, q, are flanges on the coils; P, p, are
solid shanks fixed to or formed on the ends of the coils B', and passing through
orifices in the passages D', E¹, and they are tapped on their outer ends to
receive nuts H, H³, by means of which and of the flanges q the coils are
tightened against the back end of the receiver. r, r, are washers; F¹ is the
outlet, and S inlet or feed pipe for the matters treated in the receiver; they
are furnished with stop-cocks f. m, m, shewn on a larger scale in longitu-
dinal section, Fig. 5, and transverse section, Fig. 6, are rods extending across
the receiver A' and resting on forked brackets n fixed to its sides; t, t, are
rollers or short hollow cylinders so fitted on the rods mas to turn freely
thereon. On these rollers and rods the coils B' rest, whereby their with-
drawal is facilitated, and as each coil rests on its own rollers, any one coil may
be readily withdrawn without disturbing the others. The coils being fitted as
described, have room or play for expansion, and hence liability to burst under
the pressure of the steam is diminished or obviated.
The only mode of cleansing the ordinary fixed spiral worm is by injecting
cleansing material into the boiler or receiver, whence certain disadvantages
result; whereas, according to my present improvements, when the coils have
to be cleansed, the nuts H' are unscrewed, the doors G³, G', opened, and the.
coils withdrawn from the receiver, and immersed in a separate vessel con-

page_text: taining acid solution or other cleasing material, so that while one coil or set
of coils is being cleansed, the boiling or other operation may still be proceeded
with in the receiver by means of another coil or coils.. A, B, indicates the
front end, and C, D, the back end of the receiver A¹; L is the pipe which
leads into the condenser.
Figure 7 is a modification in which the ends of the coils B', instead of
leading into horizontal passages D¹, E', communicate through junctions V with
vertical pipes K', and are fitted with nuts, the outer nuts and the inner hollow
nuts o, which work on the junctions V.
Having now described the nature of the said Invention, and in what manner
the same may be performed, I declare that I claim,-
First, the employment of coils arranged removable and capable of being
replaced, as described.
Second, the mode of securing and tightening the coils by nuts, as
described.
Third, the mode of supporting the coils on rods and rollers, as described.
Fourth, the general arrangement and combination of apparatus described.
In witness whereof, I, the said Jean Michel Vanderfeesten, have here-
unto set my hand and seal, this Sixteenth day of June, in the year
of our Lord One thousand eight. hundred and sixty-four.
Witness,
M. HENRY,
Patent Agent,
