AN IMPROVED PROCESS FOR THE MANUFACTURE OF LINSEED OIL AND APPARATUS THEREFOR
Year: 1884

page_text: I WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake, and Co. Patent Agents,
Southampton Buildings, in the County of Middlesex do hereby declare the nature
of said Invention for " AN IMPROVED PROCESS FOR THE MANUFACTURE OF
LINSEED OIL AND APPARATUS THEREFOR" and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
The object of this Invention is to provide the means for the manufacture of
linseed oil whereby more oil can be made from a given quantity of ground or other
seed and of a better quality than that made in the ordinary way, all of which will
be more clearly hereinafter shewn by reference to the accompanying Drawing in
which
Figure 1 is a front elevation of the apparatus I employ, a portion being in
section to show the interior of the same, and,
Figure 2 represents a side elevation through the line X X Figure 1.
a represents the usual hydraulic press by which the required pressure is given to
the ground flax seed, all of which is of well known construction for pressing out
linseed oil, and requires no further description here; b is a series of steam-pipes
constructed and connected in any well known way for giving the required heat.
c is a portion of the room floor in which the presses are located.
The steam-
heating apparatus, b, and the presses are surrounded by a casing d, having a
door, e, directly opposite each press. The casing is made of wood, sheet iron or
other suitable material and encloses the press, or a number of the presses so as to
separate or insulate them from the room in which they are placed. In the
manufacture of linseed oil I have found that more oil, and of a clearer and better
quality, can be got from a given pressure and quantity of seed or ground flax seed
by having the presses in which the oil is pressed kept at a temperature of from
110° to 140° Fabrenheit about 130° or 140° being preferable. If the room in
which the workmen are employed is kept at so bigh a temperature it would be
impossible for them to work to advantage, the peculiar odour of the heated oil
and the heat has a very depressing effect upon them and renders it impossible for
77

enclose the presses within a casing. d, entirely surrounding them so as to separate
the heated space around the presses from the rest of the room in which the
workmen are employed. In operating the presses it is only necessary to keep the
doors, e open for a short time while putting the ground seed into the press or
taking the oil-cake out. Under the high temperature above mentioned and the
usual pressure, the oil flows out more freely as it becomes more fluid under the
heat and carries out less of the impurities in the meal with it.
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
First. In an oil press for pressing out linseed oil, the combination therewith of a
casing, d, provided with a door e, and a suitable heating device or coils, b, arranged
within the casing, d outside of the press and provided with a stop-cock. for
regulating the amount of steam admitted so that the required temperature may be
maintained within said casing while the press is in operation, as described.
Second. The herein described process of manufacturing linseed oil, consisting in
pressing it out from the ground seed under a temperature of from 110° to 140°
Fahrenheit by means substantially as specified.
