HUGUENIN, of Brook Street, in the Parish of Saint Andrew, Holborn, in the
County of Middlesex, Engineer, send greeting.
WHEREAS His present most Excellent Majesty King George the Third, in
and by His Letters Patent under His Great Seal of the United Kingdom of
Great Britain and Ireland, bearing date at Westminster; the Thirteenth day
of November, in the forty-third year of His reign, for Himself, His heirs and
successors, did give and grant unto me, the said Simon Huguenin, my execu-
tors, administrators, and assigns, His especial licence, full power, sole privilege
and authority, that I, the said Simon Huguenin, my executors, administrators,
and assigns, and every of them, by myself and themselves, or by my and their
deputy or deputies, servants or agents, or such others as I, tho said Simon
Huguenin, my executors, administrators, and assigns, should at any time agree,
and no others, from time and at all times thereafter during the term of
fourteen years therein expressed, should and lawfully might make, use, exercise,
and vend, within that part of His said Majesty's United Kingdom called
England, His Dominion of Wales, and the Town of Berwick-upon-Tweed,
and also in all His said Majesty's Colonies and Plantations abroad, "A MACHINE
CONSTRUCTED WITH ECCENTRIC WHEELS ON CYLINDERS, WITH OR WITHOUT TEETH,
WHICH BEING AFFIXED TO OR PLACED WITH A LEVER OR LEVERS, WITH OR WITHOUT A

page_text: CHAIN OR RAKES ON OTHER BODIES, WILL RENDER THEM SUPERIOR TO ALL OTHER
POWERS HITHERTO INVENTED FOR ACCELLERATING MOTION WITH LITTLE FRICTION, AND
ALSO CAPABLE OF RECEIVING MOTION BY THE APPLICATION OF A MECHANICAL POWER,
BY WHICH THEY WILL EFFECT THE RAISING OR DEPRESSING OF ANY WEIGHT, AND
APPLY FORCE WITH MUCH LESS LABOR AND MORE FACILITY THAN HAS HITHERTO BEEN
ACCOMPLISHED, AND WHICH MACHINE IS WELL INTITLED TO THE APPELLATION OF 'THE
UNIVERSAL LEVER;'" in which said Letters Patent is contained a proviso,
obliging me, the said Simon Huguenin, by an instrument in writing under my
hand and seal, particularly to describe and ascertain the nature of my said
Invention, and in what manner the same is to be performed, and to cause the
same to be inrolled in His Majesty's High Court of Chancery within one
calendar month next and immediately after the date of the said recited Letters
Patent, as in and by the same, relation being thereunto had, will more fully
and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Simon Huguenin, do hereby describe and ascertain the nature of my said
Invention, and the manner in which the same is to be performed, by the plan
or Drawing hereunto annexed or affixed, and as follows, that is to say:―
The principal advantage of this new method of eccentric wheels or rollers
acting with any lever from their pivots, is that, as they act or move several
together, they press or depress more than any other lever or crank, without
deviating so much from the center line, the point of pressure remains always
near the perpendicular, as is demonstrated Fig. D, No. 1, 2, 3, 4.
The Figure A represents the perspective view of a machine, constructed with
two levers, each of which are elevated upon two simple rollers or eccentric
wheels, which, once in motion by the axletree, press and depress the levers,
alternately moving upon the center line, without diverging more than three
inches from it. No. 1, Figure A, represents the crank fixed upon the axis,
and the connecting rod of a steam engine, to produce the action, which may
be replaced by any other power or purchase. No. 2, Figure A, represents
the axletree. No. 3, Figure A, represents the fly at the other end of the axle-
tree. No. 4, Figure A, represents the two eccentric wheels fixed upon the axis,
which acts with the two following. No. 5, Figure A, represents the other two
wheels fixed in their levers: see Fig. C. No. 3, Figure A, represents the two
larger levers. No. 7, Figure A, represents the two double levers or counter
bearings, at the end of which may be worked a pump, or any other machinery
may be put in motion. No. 8, Figure A, represents two small rollers fixed at
the opposite end of the double levers, which acts as counter bearings against
the eccentric rollers fixed upon the axis, which, by assisting the motion, rises

page_text: and falls considerably more on the other end without changing the first
power. Figure B is the same machine, shewing the front view.
Figure C represents the two large levers, with part of the double levers seen
in ground plan. No. 1, Figure C, represents the extremities of the double
levers, which are fixed to the end of the large lever by a pin, which goes through
it, as is demonstrated No. 7, Figure A. No. 2, Figure C, represents the
excentric wheel fixed by a pin in the great levers: see No. 5, Figure A.
No. 3, Figure C, represents the extremity of the great levers, fixed upon the
frame by two points or pivots.
Figure D rrepresents two eccentric wheels as acting together in four different
positions in their circumference, as seen No. 1, 2, 3, 4. No. 1, Figure D,
represents the point of pressure and the position of the two wheels when the
lever is come to the lowest part of its action; in this position the smallest
purchase on the crank set them in motion. No. 2, Figure D, represents the
above-mentioned wheels upon the point of pressuro; when it is the farthest from
the centre this position requires more purchases, but it is likewise the position
in which the crank has most power with the connecting rod, being ninety
degrees upon the perpendicular of the circle. No. 3, Figuro D, represents the
position of the above wheels when the lever is at its greatest elevation, and then
the pressure is returned on the perpendicular of the axis. No. 4, Figure D,
represents these eccentric wheels when the lever is half down; then the point
of pressure is the same distance from the center as No. 2; in this point the
pressure it receives by the lever assists the other levers, which is then rising.
Figure E represents the same eccentric wheels as represented by Figure D,
but in a perspective view; four of them are fixed on an axis in four different
positions fit to put in motion four levers alternately; the four other wheels are
to be fixed to the levers.
Figure F represents the front of a machine constructed as that one marked
Fig. A, with the difference that in this one the wheels or rollers fixed on its
axis form in their circunference two curves, which deviate from the centre,
consequently each revolution of the crank occasions two motions to each
lover.
Figure G represents the front form and position of the two wheels or rollers
fixed upon the axis of the machine, Fig. F, with two smaller eccentric wheels
which act with them, and which should be fixed to the levers as follows:
No. 1. Figure G, represents the crank and the end of the axis; No. 2,
Figure G, represents the wheels fixed upon the axis in the position where the
lever is come to the lowest part of its action; No. 3, Figure G, represents the
wheel or roller which should be fixed in the great lever; No. 4, Figure G,

page_text: represents the other wheel or roller to be fixed to the double lever; No. 5,
Figure G. represents the wheel or roller fixed on the axis when the lever is at
its greatest elevation; No. 6, Figure G, represents the eccentric wheel to bo
fixed to the lever; No. 7, Figure G, represents the other eccentric wheel to
be fixed to the other lever. The construction of this machinc, Figure F, has an
advantage upon that of Figure A in case of slow motion, as, for instance, a
steam engine that would require a crank of three feet from the axis could
hardly produce more than twelve revolutions in a minute; but by the con-
struction of this machine, Fig. F, cach lever having two motions for one
revolution, consequently it will produce twenty-four strokes in a minute, i. e.,
the two will produce forty-eight strokes. This construction has likewise the
advantage that the point of pressure remains always in the centre; but this
method requires a longer crank, because the wheels or rollers fixed on the axis
are larger. I have likewise made several wheels fixed upon the axis, which
presented three or four curves deviating from the center, but they do not
answer the purpose so well as this with two curves.
Figure H represents two half wheels or rollers, which act together upon the
half of the circumference. The principal is the same as the whole rollers; the
difference is that to these the power or purchase must be retrogrative, and
they will not admit of a fly. No. 1, Figure H, represents the half roller which
should be fixed to the axis. No. 2, Figure H, represents the other, to be
fixed to the lever; they will likewise admit a double lever as the others. This
method is very good for fire engines, or any other small single pump, in which
the power or purchase should be retroactive.
In witness whereof, I, the said Simon Huguenin, have hereunto set my
hand and seal, the Eleventh day of December, in the forty-third year
of the reign of our Sovereign Lord George the the Third, by the Grace
of God, of the United Kingdom of Great Britain and Ireland, King,
Defender of the Faith, and in the year of our Lord One thousand
eight hundred and two.

page_text: AND BE IT REMEMBERED, that on the same Eleventh day of December,
in the year above mentioned, the aforesaid Simon Huguenin came before our
Lord the King in His Chancery, and acknowledged the Specification afore-
said, and all and every thing therein contained, in form above written. And
also the Specification aforesaid was stamped according to the tenor of the
Statute in that case made and provided.
