ARCHIMEDEAN SCREW TO THE PRODUCTION AND TRANSMISSION OF MOTIVE POWER,
AND IN THE APPARATUS CONNECTED THEREWITH." -A communication from

PROVISIONAL
SPECIFICATION left by the said Marc Antoine Francois
Mennons at the Office of the Commissioners of Patents, with his
Petition, on the 6th September 1861.
1, MARC ANTOINE FRANCOIS MENNONS, of the British and Foreign Patent
Offices, 39, Rue de l'Echiquier, Paris, in the Empire of France, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN THE APPLICA-
TION OF THE ARCHIMEDEAN SCREW TO THE PRODUCTION AND TRANSMISSION OF MOTIVE
POWER, AND IN THE APPARATUS CONNECTED THEREWITH," to be as follows:-
The Invention communicated to me consists in the substitution, as bereafter
described, of the archimedean screw for the hydraulic wheels and similar motors,
by means of which water power is commonly applied to the production of
mechanical action.

page_text: To this end one or several screws of ordinary construction are mounted
horizontally on an iron bridge or framing, the extremities of which are set on
closed metallic cylinders of suitable dimensions and strength. In the bed of
the river are formed two pile foundations spaced to correspond with the extre-
mities of the above arrangement, which is sunk into position with the axes of
the screws parallel to the current by filling with water the metallic cylinders.
These cylinders may be emptied by pumps when required to be brought to
the surface or otherwise moved. The power developed by the screw or screws
thus submerged is applied to the millwork or other machinery erected on the
bank of the watercourse by means of horizontal and vertical transmission gear
communicating with the different points at which the movement is required.
The same principle may be adopted in the construction of floating mills, the
submerged screws being in this case mounted in a framing set between coupled
pontoons, on which the machinery to be driven is erected.
The general details of construction and arrangement of the transmitting
mechanism vary according to the position of the motor and the nature of the
millwork to which it is applied.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Marc Antoine Francois Memmons in the Great Seal Patent
Office on the 5th March 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MARC
ANTOINE FRANCOIS MENNONS, of the British and Foreign Patent Offices,
38, Rue de l'Echiquier, Paris, in the Empire of France, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of September, in the year of our Lord
One thousand eight hundred and sixty-one. in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Marc Antoine Francois Mennons. Her special licence that 1, the
said Marc Antoine Francois Mennons, my executors, administrators, and
assigns, or such others as I, the said Marc Antoine Francois Mennons, 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 THE APPLICA
TION OF THE ARCHIMEDEAN SCREW TO THE PRODUCTION AND TRANSMISSION OF MOTIVE

page_text: POWER, AND IN THE APPARATUS CONNECTED THEREWITH," (a communication from
Julius Sturm (C.E.), a person resident at Mannheim, in the Grand Duchy
of Baden,) upon the condition (amongst others) that I, the said Marc Antoine
Francois Mennons, 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 1. the said Marc Antoine Francois Mennous, 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, reference being had to the figures of the accom-
panying Drawing, and to the letters marked thereon, that is to say:-
The Invention communicated to me consists in the substitution, as hereafter
described, of the archimedean screw to the hydraulic wheels and similar motors,
by means of which water power is commonly applied to the production of
mechanical action. To this end one or several screws of ordinary construction
are mounted horizontally on an iron bridge or framing, the extremities of which
are set on closed metallic cylinders of suitable dimensions and strength. In
the bed of the river are formed two pile foundations, spaced to correspond
with the extremities of the above arrangement, which is sunk into position
with the axes of the screws in parallel line with the current by filling with
water the metallic cylinders. These cylinders may be emptied by pumps
when required to be brought to the surface or otherwise moved.
The power
developed by the screw or screws thus submerged is applied to the millwork
or other machinery erected on the bank of the watercourse by means of hori
zontal and vertical transmission gear communicating with the different points
at which the movement is required. The same principle may be adopted in
the construction of floating mills. the submerged screw being in this case
mounted in a framing set between coupled pontoons, on which the machinery
to be driven is erected.
Figures 1, 2, 3, of the annexed Drawing represent, on a scale of 100, an
application of the Invention to floating mills. A. A. are the coupled pontoons;
B, archimedean screw; C. C', bevel wheels: D. vertical shaft: F. brake;
G, mill gate; H, lever of the same; I, stage of the motor with its beam.
Figures 4, 5, represent on the same scale a 100 H. P. motor applied to
millwork erected on the river bank. A, A'. A", screws, set on the cross beams
of the stage or framing B; C, C, iron cylinders, which are filled with water

page_text: when being sunk into position, and exhausted by pumping when required to
be brought to the surface or otherwise moved. D, D¹, pile foundations of the
cylinders C, C; E, E, moveable stage, communicating with the bank: F, F,
warps of the saine; G. C, G", cranks; II, connecting rods; 1, K, trans-
mission gear; L, centrifugal wheel.
From the preceding examples it will be seen that the Invention may be
applied to the production of power in all localities possessing a watercourse of
sufficient depth and speed, the transmission gear being in each case varied
according to the position and nature of the millwork or other machinery to
be acted upon.
Among the advantages resulting from such applications may be noted:
1stly, economy in space. in cost of construction, and in working expenses.
2ndly, non-liability to injury from driving ice and other obstructions.
3rdly, production at will of any required amount of power by multiplying
the number of screws in each watercourse.
Having now described the nature of the said improvements. and the manner
in which they may be carried into effect. I would have it understood that I do
not confine myself to the general details of construction and arrangement
above laid down. as these may be modified according to circumstances with-
out deviating from the principles or main features of the Invention; but what
I claim. and desire to protect by the herein-before in part recited Letters
Patent is, the application, substantially as herein set forth and represented in
the Drawing. of the submerged archimedean screw to the production of motive
power, and the translation thereof to floating or stationary millwork and other
machinery.
In witness whereof. 1. the said Marc Antoine Francois Mennons, have
bereto set my hand and seal, this First day of March, in the year of
our Lord One thousand cight hundred and sixty-two.
M. F. MENNONS. (..s.)
