Invention of "IMPROVEMENTS IN APPARATUS FOR BOILING STARCH-CONTAINING
MATTERS UNDER STEAM PRESSURE, AND EMPLOYED IN THE MANUFACTure of
ALCOHOL." A communication from abroad by Count Sixtin de Sparre, of
Paris, France.

PROVISIONAL SPECIFICATION left by the said Peter Jensen at the Office of
the Commissioners of Patents on the 4th November 1879.
PETER JENSEN, of 33, Chancery Lane, London. "IMPROVEMENTS IN APPARATUS
FOR BOILING STARCH-CONTAINING MATTERS UNDER STEAM PRESSURE, AND
EMPLOYED IN THE MANUFACTURE OF ALCOHOL." (A communication from abroad
by Count Sixtin de Sparre, of Paris, France.)
The main object of this Invention is to apply high pressure steam with certainty
and equality of action for the boiling of potatoes, maize, and other starch con-
taining matters for the production therefrom of alcohol, and thus to prevent the
burning of the matters under treatment, which sometimes happens in the use of
the closed steam pressure boiling apparatus known as "Ellenberger's," and described
in the Patent Specification, No, 3724, of 1876.
For this purpose the said boiling apparatus is according to this Invention
constructed or modified as follows:-It is provided with, say, two openings for
the steam inlets in the lower part as before, and is fitted with a mixing apparatus
consisting of a central vertical shaft peferably passing out through the top cover,
and resting in a step at the bottom; it is fitted with a series of screw twisted bars
or mixing arms arranged preferably in sets vertically, and in two sets, one opposite
the other, each set in the vertical height consisting of, say, three arms, one nearly
touching the side of the vessel, the next following arranged below it but much
shorter, and the third about the same length as the last named one, but on the
opposite side of the shaft; this latter is also fitted with arms in the lower or conical
part of the vessel.
The mixer may be worked by suitable wheel gearing, say, by bevil wheels.
By the action of this mixer the matters under treatment are constantly turned
over and mixed and exposed to the steam in such a manner that no part is burnt
or unduly acted upon by the steam.

the said Peter Jensen in the Great Seal Patent Office on the 4th May 1880.
PETER JENSEN, of 33, Chancery Lane, London. "IMPROVEMENTS IN APPARATUS
FOR BOILING STARCH CONTAINING MATTERS UNDER STEAM PRESSURE, AND
EMPLOYED IN THE MANUFACTURE OF ALCOHOL." (A communication from abroad
by Count Sixtin de Sparre, of Paris, France.)
The main object of this Invention is to apply high pressure steam with certainty
and equality of action for the boiling of potatoes, maize, and other starch con-
taining matters for the production therefrom of alcohol, and thus to prevent the
burning of the matters under treatment which sometimes happens in the use of the
closed steam pressure boiling apparatus, known as Ellenberger's, and described in
the Patent Specification, No. 3724, of 1876.
For this purpose the said boiling apparatus is according to this Invention con-
structed or modified as follows:-
It is provided with, say, two openings for the steam inlets in the lower part as
formerly, and is according to this present Invention fitted with a mixing apparatus
consisting of a central vertical shaft preferably passing out through the top cover
and resting in a step at the bottom; it is fitted with a series of screw twisted bars
or mixing arms arranged preferably in sets vertically, and in two sets one opposite
the other, each set in the vertical height consisting of, say, three arms, one nearly
touching the side of the vessel, the next following arranged below it but much
shorter, and the third about the same length as the last named one, but on the
opposite side of the shaft, this latter is also fitted with arms in the lower conical
part of the vessel.
The mixer may be worked by suitable wheel gearing, say, by bevil wheels.
By the action of this mixer the matters under treatment are constantly turned
over and mixed and exposed to the steam in such a manner that no part is burnt
or unduly acted upon by the steam.
And in order that this Invention may be more fully understood I will now
proceed to describe the same with reference to the accompanying Drawing, which
represents a vertical section of a boiling apparatus constructed according to this
Invention.
The vessel a is fitted with a central vertical shaft b which rests in a step bearing
c at the bottom and passes out through a stuffing box k in the cover d. At the top
on the shaft b are fixed a number or sets of mixed arms or bars j arranged as shewn,
the five upper sets of arms being in this case arranged in threes, two on one side,
and the third on the opposite side; there are also arms in the lower or conical part
of the vessel a.
The shaft b is driven by bevil gearing e, f, and strap pulley i on spindle g which
has its bearing in the bracket h. The arms jare screw twisted, and form together,
as it were, a screw thread. Although I have described a continuously revolving
mixer as a suitable way of carrying out this Invention, I do not confine myself to
such, as a mixer with an intermittent, or oscillating, or other movement may be
applied.
And having thus described and ascertained the nature of this Invention, com-
municated to me, I declare that I claim,-
Firstly. The application of a mixer to the boiling apparatus herein before referred
to, and
Secondly. The special construction of mixer, substantially as hereinbefore
described and shewn.
In witness whereof, J, the said Peter Jensen, have hereunto set my hand and
seal, this Fourth day of May, in the year of our Lord One thousand eight
hundred and eighty.
