page_text: LETTERS PATENT to Juan Duran, of the Puerta del Sol, Madrid, in
the Kingdom of Spain, Gentleman, for the Invention of "OBTAIN-
ING AND APPLYING MOTIVE POWER."
Sealed the 17th June 1853, and dated the 21st April 1853.
COMPLETE SPECIFICATION filed by the said Juan Duran at the
Office of the Commissioners of Patents, with his Petition and
Declaration, on the 21st April 1853, pursuant to the 9th section of
the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I.
Juan Duran, of the Puerta del Sol, Madrid, in the Kingdom of
Spain, Gentleman, do hereby declare that the nature of the Inven-
tion for "OBTAINING AND APPLYING MOTIVE POWER," and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement thereof, reference being had to the
drawings hereunto annexed, and to the figures and letters marked
thereon, that is to say;

page_text: The object of my Invention is the obtention of perpetual motion,
and the application of such motion, when so acquired, to machinery or
apparatus of various descriptions.
I think it unnecessary to dilate on the utility of my Invention,
because as the means by which I obtain power are fully herein-after
described and illustrated by the drawing hereunto annexed, all com-
petent persons will at once be able to judge thereof.

DESCRIPTION OF THE FIGURES IN THE DRAWING.
Figure 1, of the annexed drawing is a wheel composed of an axle-
tree, eight arms, and three rings or circles, the principal of which is the
middle one placed over the eight arms fixed upon the wheel. The
said principal ring has sixteen posts invisible in the drawing, because of
their being hidden by the ring; there are eight posts on each side.
These posts are. fixed also to the two outer rings by the means of the
screws designed from 1, to 8, in the plan.
"
It is to be remarked (Figure 1) that there is all around the wheel a
mechanism by which the wheel is kept always excentric and out of its
equilibrium; the weight being heavier on one side, the motion is the
necessary result of such a contrivance.
Around the said wheel are twenty-four small wheels of equal size
(Figure 2)-with twenty-four axle-trees (Figure 3,) on which are fixed
the twenty-four small wheels; the twenty-four weights (Figure 4.)
placed by the means of screws set up at the extremity of each arm
(Figure 3).
Figure 5, shows a wheel with its axle-tree and weight. The external
ring is furnished with twenty-four levers (Figure 6,) fixed in the
internal part of the ring by the means of a screw and two supports.
The aforesaid levers have equally twenty-four detents let into a rest
secured in the superior part of the said levers.
Figure 8, shows the rest and the screw which serves to fix the
detent, and allows a small degree of motion thereof hereafter men-
tioned. Likewise each of the detents has a watch pin placed in the part

page_text: opposite to the place wherein the detents are set up; hereafter; their
use is explained.
Figure 9, shows a lever with its detent. Figure 10, shows also a
detent with its watch pin..
Figure 11, shows the support which maintains the propelling wheel
by its two spindles belonging to the centric axle-tree. Figure 12, is
the screw of the two sides of the support, serving to raise up the
cushions indicated by a line in the point A; where rest the two spindles
leading to the axle-tree of the propelling wheel. There is to be seen
the horizontal line directed towards the centre where the spindles; are
resting. This line shews the separation or the junction of the two
pieces by which are covered the spindles of the axle-tree, fixed by
means of a screw on both sides.
Figure 13, is a rack or ratchet wherein the catching of the wheels
on their passage is operated (No. 2). The said rack is maintained by a
support, which mounts to the plate fixed upon the basis of the support
by a screw, which is set up underneath. The plate is likewise fixed-by
four screws, two on each side, as in plan. There are two screws placed
under the said plate penetrating it. thoroughly; they serve, to raise up
the rack on one or both sides....
Figure 14, is also a rack, wherein the catching of the same wheels
is operated (Figure 2,) for the reproduction of the power.
EXPLANATION OF WORKING OF THE MECHANISM.
Figure 1, represents the machine in motion. There is to be seen
in this state ten weights constantly developed on, the right side,
and ten others closed up on the left side. It is essential to bear in
mind that incessantly also two weights tend to develope themselves
the superior part of the top in the same time as two other weights act
in the contrary sense at the bottom, shutting up or dissecting them-
selves towards the centre, whilst the top weights accomplish their
development (unfolding). Such is the perfection of this,mechanism
that the ten weights constantly developed on the right, beyond and
without the limits of the propelling wheel, though they are equal in

page_text: number to the ten weights rammed towards the centre, produce by their
eccentricity (by which the power of the weight is increased) the motion
of the said wheel. This wheel is under the pressure of a weight deter-
mining its progressive declension, and when the wheels (No. 2) reach
the point B, of the rack or ratchet (Figure 13), the greater gravity of
the wheel on its right obliges it to make nearly a half circle by means
of the catching which takes place in that part, and during the time
wherein the wheel is making its rotary revolution.
The angle C
which is in the wheel, forces by the means of the watch-pin with
which each detent is furnished to go up anew towards the zenith in
such a manner as, in the very moment when the catching reaches its
end, the detent, yielding to its watch-pin, goes back or folds itself
towards the centre into the place secured at the point D, and remains
confined there till it arrives at the point E, of the rack or ratchet
(Figure 14). This ratchet or rack by its specific gravity goes down,
and the wheel (No. 2) is enabled to make its revolution by means of
the reproducing power of the catch.
Through the means of the safety guard, figure 15, the machine can
never stop, because of the watch pin fixed on the detent protruding within
and without. Now, the inside part serves to fix the wheel, the catching
of the bottom is at end, and the outside part causing a slide towards the
point F, through the inclined plane of the said safety guard, would
determine the unfolding of the detent, even when it would not have
been produced beforehand by the ordinary provisions of the mecha-
nism.
The wheels (Figure 2) have each thirty notches, fourteen of the
teeth of which are long for the bottom catch, and sixteen short for the
top catch. It is right to observe that thirteen of the first-mentioned
notches cut in the part opposite the long ones, serve to raise up the
weights as far as they produce the motion of the propelling wheel.
As for the three others, two serve to propel the wheel and weight,
until one of the arms of the said wheel (Figure 2) be at rest on the
notch pin placed in the external circle for each wheel; the third notch
is without any effect. It is in this manner that the weights generate

page_text: centre by means of the bottom catching, they become inactive.
MODE OF INCREASING THE FORCE ACCORDING TO A DETERMINED
DIAMETER.
The wheel No. 1, has three rings. These rings form two compart-
ments, separated from each other, and supported by the sixteen posts
here above-mentioned. In each of these compartments may be placed
a mechanism similar to the one already described. When one single
mechanism produces one-horse power, two mechanism would of course
produce the double, and so on in such a manner; as, if it were necessary,
it would be easy to augment the mechanisms on the same axle-tree for
obtaining the required power; the solidity and length of the axle-tree
would also allow the addition of new mechanisms.
Two notched wheels have been placed to the extremities of the
axle-tree, and they serve to communicate the power to any machine,
whatever form or use it may have; one of these wheels only is to be
seen on the plan, as the plan shows but one of the lateral faces of the
machine. It is the same for the support, as one half part of its extent
may be perceived.
Having now described the nature of my Invention, and the means
by which I carry it into practical effect, I desire it to be understood
that although I have given the best description in my power, and that
I believe the different parts of the apparatus or mechanism used are
shewn in their best relative proportions, I do not confine myself to the
exactitude of such proportions, as it may be found necessary to varify
or modify the same in some instances, or under peculiar circumstances;
but such variations or modifications would be comparatively slight, as I
conceive both the principle and details of my mechanism are correctly
detailed and shewn. I do not claim the parts of my mechanism, taken
separately, many of such having been used for various purposes and in
various apparatus. But what I do claim is, the combination of parts

page_text: herein described and shewn, by the use of which I obtain perpetual
motion capable of being applied to machinery.
In witness whereof, I, the said Juan Duran, have hereunto set
my hand and seal, this Sixth day of April, in the year of our
Lord One thousand eight hundred and fifty-three.
