page_text: County of Middlesex, Patent Agent, for the Invention of "A NEW
SYSTEM OF WINDMILL-A communication from abroad by Bernard
Zacharie Lethiers, No. 10, Rue Mogador, Paris, in the Empire of
France...
Sealed the 13th December 1859; and dated the 18th June 1859.
PROVISIONAL SPECIFICATION left by the said Joze Luis at the Office
of the Commissioners of Patents, with his Petition, on the 18th June
1859.
-I, JOZE LUIS, of the British & Foreign Office for Patents, No. 1";
Welbeck Street, Cavendish, Square, London, in the County of Middlesex,
Patent Agent, do hereby declare the nature of the said Invention for "A
NEW SYSTEM OF WINDMILL," (& that it has been communicated to me from
abroad by Bernard. Zacharie Lethiers, No. 10, Rue Mogador, Paris, in, the
Empire of France, to be as follows:-
7
The sails are twelve in number, and are made of thin battens; each. of these
sails are composed of two parts, the principal & counter sail, and these two
parts are united by means of metal bands, and thus rendered perfectly solid.
The sails thus constructed are fixed by springs on 12 arms of wood; six of
them are fastened to a cast-iron bar keyed to the driving shaft; the six other
arms are simply bolted to the crown of the cast-iron bar. These twelve arms
[Price Sd.]

page_text: are bound together by an iron hoop. There are two springs or fastenings to
each sail, and they are placed in front of the metal bands.
The machinery for changing the position of the sails is moved by a small
set of sails placed in front on the same shaft, round which it freely turns; it is
held in place by a washer and screw bolt. This small mill regulates the
action of the wind on the driving sails; it is composed of six sails adjusted in
a nave or box of cast-iron; in this nave three grooves are cut to receive the
chains, which are fixed at one end to a knob or button, at the other end to an
iron square fixed on three of the wings passing on return pullies, in such a
manner that on the regulating sails turning faster than the driving sails, the
chains wind up on the nave, and cause the large sails to take the required
position. In order that this movement may not exceed a certain limit, each
sail is furnished with an iron sector moving in the iron hoop or band above
mentioned, which binds the sails together. The sector is furnished with two
stops to fix the limit of the variations in the slope of the wings.
'
The mechanism just described is only adapted to three of the large sails,
but as each sail is united to the other by jointed arms, all the sails act together
regulated by the six small regulating sails.
In order to stop the mill, the cast-iron cross bar (on which the sails are
fixed) carries a ring, on which an iron hoop acting as brake bears; it is moved
by a cord attached to the end of, a lever, the resting point of which is fixed by
means of a bolt on the moveable frame; the brake is worked by pulling the
cord by hand.
The driving shaft of the mill acted on by the sails can be adapted so as to
work a pump or millwork, or otherwise, as may be desired. The shaft is
supported in two bearings fixed on the framework forming the moveable cage
of the mill. A guide or rudder is fixed on the framework to guide the mill.
A collar of cast-iron is fixed to the framework, and the whole is supported on
a cage of wood covered with zinc; a ring of cast-iron binds the lower ends of
the uprights of the framework together, and serves to secure it on the wooden
cage or body.
By means of the present arrangement the sails are always presented to the
wind which acts equally on each, the sails offering a surface in accordance
with force of the wind. The number, size, shape, and material of which the
sails are constructed would, of course, vary according to circumstances.
This system of motive power is applicable to all usages in which wind can
be employed, such as pumps, mills, thrashing machines, &c.
.

by the said Joze Luis in the Great Seal Patent Office on the 15th
December 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, Joze
LUIS, of the British and Foreign Office for Patents, No. 1B, Welbeck Street,
Cavendish Square, London, in the County of Middlesex, Patent Agent, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by. Her Letters
Patent, bearing date the Eighteenth day of June, 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 Joze Luis, Her special licence that I, the said Joze Luis, my
executors, administrators, and assigns, or such others as I, the said Joze
Luis, 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 "A NEW SYSTEM OF WINDMILL,"
a communication from abroad by Bernard Zacherie Lethiers, No. 10, Rue
Mogador, Paris, in the Empire of France, upon the condition (amongst
others) that I, the said Joze Luis, 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 I, the said Jose Luis, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement and accompanying Drawings, that is to say:-
The sails of the mill are twelve in number, and are made of thin battens;
each of these sails is composed of two parts, the said B and. the counter sail C,
which are connected as shown, Fig. 4; the metal plates or bands V, Fig. 3,
render them perfectly solid. The sails thus constructed are fixed by the
springs (e), see Fig. 4, on twelve wooden arms C'; six of them are adjusted on
the cross bars D keyed on the driving shaft E; the six other arms are simply
bolted on the crown of the cross bars D see Fig. 1. The twelve arms are

page_text: bound together by an iron hoop K.
fronting the bands V, see Fig. 3.
There are two springs to cach sail placed
The mechanism which causes the position of the sails to vary is moved by a
little windmill placed in front on the same shaft, and around which it can turn
freely; it is held in its place by a washer and nut screw. This small windmill
I denominate regulator, as its effect is to regularize the action of the wind on
the driving sails; it is composed of six sails adjusted in a nave of cast iron,
in which three grooves are cut receiving the chains y, shown by the blue lines
on the Figs. 1, 2, 3. The chains are fixed at one end to the knob L, and at
the other to a square of iron o fixed on the sails B', (see Figs. 1, 4,) and
passing on the return pullies n, m, so that if the regulator turns quicker than
the mill sails, the chains wind upon the nave, and cause the sails to take the
position shown. Fig. 4; in order that the movement does not exceed a certain
limit, as shown in the Drawings, each sail is furnished with an iron sector G
adjusted to the hoop or band K. This sector is furnished with two stops
h, i, which determine the limit of the two variations of the slope of the
sails.
The mechanism just described is only adjusted to three

sails,.but each sail
sails act together,
The mill is stopped by means of a frame adapted to the cross bars D, on
which an iron hoop acting upon it as brake, and moved at will by means of a
cord fixed to the end of a lever q', which has its resting point on the movable
frame L, to which it is bolted.
The shaft at E has the form of a crank T, so as to move a pump rod. This
shaft is supported in two bearings H fixed on the framework L, which forms
the body of the mill.. This arrangement may of course be modified according
to the purpose for which the mill is intended, whether to work a pump or
otherwise.
R indicates a rudder which serves to guide the mill; O, a collar of cast
iron fixed to the frame L; P, a wooden framework covered with zinc sup-
porting the entire apparatus; q is a cast-iron ring binding the lower part
of the uprights of the frame L, and serving to maintain them on the body of
the mill. The sails always turn to the wind, which acts equally on them all;
one of them would be unable to move without the rest, except on the breakage
of some part, the repairing of which, however, can be promptly and easily
effected. The number and size of the sails vary according to circumstances,
and may be made either of sheet iron, wood; or otherwise.

page_text: The springs which maintain the sails permit them to yield according as
required by the power of the wind; they may vary in form and position, and
can be made of any elastic matter.
By means of the regulating sails a uniform velocity is obtained, and the
rapid changes caused by squalls and gusts of wind are avoided; in short, by
means of the regulating sails, the sails of the mill always present a surface in
accordance with the force of the wind.
This system of motive power can be applied to all the purposes where wind
can be employed, such as pumps, grinding mills, thrashing machines, and
others.
The accompanying Drawings represent the application of this system to a
pump for supplying a village.
Having thus described my Invention and the means by which the same is
carried into effect, I wish it to be distinctly understood that I do not confine.
myself to the precise details, as the same may be varied or modified without
departing from the principle; what I claim is, the system or arrangement as
above described and shown in the accompanying Drawings.
In witness whereof, I, the said Joze Luis, have hereunto set my hand
and scal, this 15th day of December, in the year of our Lord One
thousand eight hundred and fifty-nine.
