page_text: LETTERS PATENT to Alphonse Couvreux, of 333, Rue Saint Martin,
Paris, in the Empire of France, and of 42, Bridge Street, Blackfriars,
London, Contractor, for the Invention of "AN IMPROVED CENTRIFUGAL
APPARATUS POR CASTING STONES AND OTHER MATERIALS, AND IN FORMING
EMBANKMENTS AND OTHER STRUCTURES."
Sealed the 18th January 1863, and dated the 15th July 1862.
PROVISIONAL SPECIFICATION left by the said Alphonse Couvreux at the
Office of the Commissioners of Patents, with his Petition, on the
15th July 1862.
J, ALPHONSE COUVREUX, of 933, Rue Saint Martin, Paris, in the Empire of
France, and of 42, Bridge Street, Blackfriars, London, Contractor, do hereby
declare the nature of the said Invention for "AN IMPROVED CENTRIFUGAL
APPARATUS FOR CASTING STONES AND OTHER MATERIALS, AND IN FORMING EMBANK-
MENTS, AND OTHER STRUCTURES," to be as follows:-
My Invention relates to an apparatus for throwing stones or any other
earthy matter required for the formation of embankments, dykes, and break-
waters. I have a large wheel which revolves at a very high speed, on, which
are placed a series of paddles or buckets, the stones are conveyed in the inside
of the frame by means of a shoot, and are taken up by these paddles or buckets
and thrown off at a tangent through another shoot which can be elevated or

mounted on a wooden frame; the wheel is driven by means of a pulley and
strap from an engine.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Alphonse Couvreux in the Great Seal Patent Office on the
15th January 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALPHONSE
COUVREUX, of 333, Rue Saint Martin, Paris, in the Empire of France, and
of 42, Bridge Street, Blackfriars, London, Contractor, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of July, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Alphonse Couvreux. Her special licence that I, the said Alphouse Couvreux,
iny.executors, administratörs, and assigns, or such others as I, the said Alphonse
Couvreux, 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, excrcise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "AN IMPROVED CENTRIFUGAL
APPARATUS FOR CASTING STONES AND OTHER MATERIALS, AND IN FORMING EMBANK
MENTS AND OTHER STRUCTURES," upon the condition (amongst others) that I,
the said Alphonse Couvreux, my executors or administrators, by an instru-
ment 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 perforined, and cause the same.to: be filed
in the Creat Scal Patent Office within six calendar months next and imme
diately after the date of the said Letters Patent....
NOW KNOW YE, that I, the said Alphonse Couvreux, 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 state-
ment:-
..
My Invention relates to an apparatus for throwing stones or any other
earthy matter required for the formation of embankments;dykes, and breaks.
waters, &c. I make use of 'a large wheel which revolves at a very high speed.
on which are placed a series of paddle or buckets the stories lare conveyed.
"

page_text: into the inside of the frame by means of a shoot, and are taken up by these
paddles.or buckets and thrown off at a tangent through another shoot which
can be elevated or lowered according to the distance they are required to be
thrown, the whole is mounted on a wooden frame, the, wheel is driven by
means of a pulley and strap from an engine, or any other convenient motive
power.
In order more clearly to illustrate my Invention and shew the best mode of
carrying the same into effect, I have to this Specification appended the accom-
panying Drawings, which taken in conjunction with the following description
will enable any one skilled in the art, to understand and practise it, but at
the same time I wish it well understood that I do not bind myself to the exact
details as berein shewn, as the same may be advantageously altered to suit
Figure 1 is a sectional elevation of my machine, through the line 1, 2,
shown in Figure 2; Figure 2 is a similar section through the line 3, 4,
(Figure 1).
It will be seen from these Drawings that the machine is composed of a large
wheel A formed with three discs of iron B, C, D, which are tied together and
strengthened by means of the angle pieces a, b, c, d, e, f, which also serve to
form the paddles or buckets before-mentioned. The discs B, C, D, aro
mounted on a spindle E, by means of the wrought-iron arms g, h, i, j, k, l,
firmly bolted to the centre disc C, which thus forms the balance of the two
others; by this means I form the wheel A, which rotates on and with the
spindle F, which is driven by means of a portable engine or otherwise as
most convenient, which gives to the wheel A a very swift movement. Tho
shaft or spindle F is mounted, and revolves in two plummer blocks or bearings
which rest on the planks ar beams H, L. On each side of the machine is a
sliding shoot M, N, which receive the stones, earth, gravel, and such like
matters and conduct them into, and between the discs B, D, where they fall
on to a sort of tray or receiver P, the wheel revolving with great speed the
paddles d, d, strike the stones, and such like, and throw them out to a very
great distance, the distance to which the stones, earth, and such like matters
are thrown, is regulated by means of the shoot R, which is fixed to the tray
or receiver P by means of a hinge and can be raised or lowered as wished.
By the use of my Invention, embankments for railways, for docks, or such
like works can be constructed very speedily, and at a less cost than at
present.

page_text: Having now described my Invention, and how the same is carried out, I
wish it understood that' what I claim and desire secured to me by the before
in part recited Letters Patent is, the use and general construction of a machine
for throwing stones, earth, gravel, and such like substances by means of
centrifugal force, substantially as herewithin described and set forth, and more
fully illustrated in the accompanying Drawings.
In witness whereof, I, the said Alphonse Couvreux, have hereunto set my
hand and seal, this Fifteenth day of January, One thousand eight
hundred and sixty-three.
A. COUVREUX. (L.B.)
