IMPROVEMENTS IN MACHINERY BREWING
Year: 1859

page_text: LETTERS PATENT to Ph. Larochette, Ainé, of Paris, in the Empire of
France, for the Invention of "IMPROVEMENTS IN MACHINERY
BREWING."
Sealed the 15th September 1859, and dated the 17th March 1859. .
PROVISIONAL SPECIFICATION left by the said Ph. Larochette at the
Office of the Commissioners of Patents, with his Petition, on the 17th
March 1859. .
I, PH. LAROCHETTE, Ainé, of Paris, in the Empire of France, do hereby
declare the nature of the said Invention for "IMPROVEMENTS. IN MACHINERY
POR BREWING," to be as follows:-
The object of this Invention is to quicken the operation of mashing in the
brewing of beer, and to stir the malt in such a manner as to obtain from it
the greatest amount of produce.
A wheel is attached to a fluted shaft, on which it rises and falls without
turning round, giving motion to two cylinders or shafts in the mash tun
furnished with blades or fans on both sides. These fans or blades are caused
to rotate, and by a mechanical arrangement have an upward and downward
motion also, so that they thoroughly stir and agitate the malt.

by the said Ph. Larochette in the Great Seal Patent Office on the
17th September 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, P.
LAROCHETTE, Ainé, of Paris, in the Empire of France, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of March, in the year of our
Lord One thousand eight hundred and fifty-nine, in the twenty-second year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Ph. Larochette, Her special licence that I, the said Ph. Larochette,
my executors, administrators, and assigns, or such others as I, the said
Ph. Larochette, 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 MACHINERY FOR BREWING," upon the condition (amongst
others) that I, the said Ph. Larochette, my executors or administra-
tors, 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 Ph. Larochette, 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, reference being had to the accompanying Drawings (that is
to say)-
The essential point of this Invention consists in fixing a wheel which can
slide up and down its shaft and at the same time not turn with it, which is
accomplished in the following manner:-
The shaft B, upon which is fixed the pulley A, is the driving shaft, and
and b.
gives motion to the hollow shaft C by means of the bevel wheels
The bevel wheel 6 turns the hollow shaft by means of a key fixed upon it
working in a groove in the eye of the wheel, allowing the hollow shaft to rise
until the boss of the cross-piece H comes in contact with it, and the machine
is lifted out of the cistern. The shaft K is fixed to the cistern by the piece J.

page_text: A slot or groove L is cut in the shaft K, in which a key on the inside of the
eye of the wheel G fits, holding the wheel from turning round, and leaves the
hollow shaft free to rise or fall. There is also a slot in the top of the shaft
serving for same purpose to the piece O, in which work the two screws N, N.
When the vertical shaft C commences to turn, it gives movement to the
cylinders E, E, by means of the spur wheels, as shewn in the Drawing. The
two cylinders E, E, carry a number of wings or flyers, by means of which the
material in the cistern is stirred up, which is accomplished from top to bottom.
The wings may be horizontal or vertical, and may move in the same direction
or in contrary directions. The piece E serves to support the wheel G when
the machine is lifted. The bottom of the cistern may be either flat, concave,
or convex, the result being the same. The pulleys S, S, serve, by means of
the bevel wheels e, f, e, f, to move the two screws N, N, which raise the
piece O to draw the machine out of the cistern. One of these pullies turns to
the right, the other to the left, and are made to turn according to whether it
is required to raise or lower the machine.
The two cylinders E, E, can be disposed horizontally, at the same time
preserving the same advantages.
Having described the nature of my Invention, and the manner of carrying
the same into practical effect, I wish it to be understood that I do not confine
myself to the precise arrangements herein described and shewn, as the same
may be varied without departing from the Invention; but what I claim and
desire to secure under the herein-before in part recited Letters Patent is, the
several improvements in machinery for brewing, substantially as herein-before
described, and shewn by the accompanying Drawings, or any mere modification
thereof.
In witness whereof, I, the said Ph. Larochette, have hereunto set my
hand and seal, this Seventeenth day of September, in the year of our
Lord One thousand eight hundred and fifty-nine.
PH. LAROCHETTE. (L.S.)
