TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PETER
BURT, of Waterloo Place, in, the Parish of Saint Ann, Limehouse, in the
County of Middlesex, Mathematical Instrument Maker; send greeting..
WHEREAS His present most Excellent Majesty King George the Fourth
did, by His Letters Patent under the Great Seal of Great Britain, bearing date
at Westminster, the Fourth day of August, One thousand eight hundred and
twenty-seven, in the eighth year of His reign give and grant unto me, the
said Peter Burt, His especial licence that I, the said Peter Burt, my executors,
administrators, and assigns, or such others as I, the said Peter Burt, my
executors, administrators, or assigns, should at any time agree with, and no
others, from time to time and at all times during the term of years therein
expressed, should and lawfully might make, use, exercise, and vend, within
England, Wales, and the Town of Berwick-upon-Tweed, the Invention of
"AN IMPROVEMENT ON STEAM ENGINES," communicated to me by a Foreigner
residing abroad; in which said Letters Patent there is contained a proviso
obliging me, the said Peter Burt, by, an instrument in writing under my
hand and seal, particularly to describe the nature of the said Invention, and
in what manner the same is to be performed, and to cause the same to be
enrolled in His said Majesty's High Court of Chancery within six calendar
months next and immediately after the date of the said in part recited
Letters Patent, reference being thereunto had, will more fully and at large
appear.

Peter Burt, do hereby describe the nature of the said Invention, reference
being had to the Drawings annexed.
This Improvement consists in inverting the cylinder in such a manner
as to have the piston rod work downwards to the crank pin, or to the end
of a lever beam to which it is attached, without any intermediate connecting
rod, pitman, or shachle bar. The-cylinder in this inverted position is sus-
pended to the frame at or near the upper end by gudgeons, pintals, journals,
or shafts lying in pedestals or boxes, so that the cylinder may be vibrated,
and the rod thereby kept in a right line with the crank pin as it revolves,
or with the end of the lever beam as it oscillates. The steam may be ad-
mitted into the cylinder through the journals or otherwise. The object of
this improvement is to apply the power more directly to produce a rotatory
or other motion than is done in common engines. The Inventor does not
claim any part of the steam engine as his Invention, but merely suspending
the cylinder in an inverted position on moveable pivots at or near the upper
end, so as to allow the cylinder to vibrate in the manner of a pendulum.
In witness whereof, I, the said Peter Burt, have hereunto set my hand
and seal, this Twenty-fifth day of January, One thousand eight hundred
and twenty-eight

and on which it vibrates. 5&6 are steam passages, of which 5 leads direct in to give the down stroke
and 6 to the side pipe leading down, the Cylinder to the lower end to give the up stroke of the Piston. 7 is
the Steam Chest in which the Valve operates to admit the Steam to pass in and out of the apertures
8&9.10 is the Eduction aperture. II. 11 are two binding screw's passing through a Strap or Cap secured
to the Journal flanch. These Screws are for tightening the pipes 12 12 by forcing the conic points to their
seats. 12,12 are best of Composition Metal. 13,13 are the pipes leading from the Steam Chest to the
conic mines and are best made of Conner
