AN IMPROVED METALLIC ENGINE TO WORK EITHER BY STEAM OR WATER, WHICH I DENOMINATE 'BODLEY'S IMPROVED METALLINE ENGINE
Year: 1816

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
BODLEY, of the County of the City of Exeter, Iron Founder, send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Twenty-seventh day of
April, in the fifty-sixth year of His reign, give and grant unto me, the said
George Bodley, my exors, adññors, and assigns, His especial licence, full
power, sole privilege and authority, that I, the said George Bodley, my exors,
adiñiors, and assigns, should and lawfully might, during the term of years
therein mentioned, make, use, exercise, and vend, within England, Wales,
and the Town of Berwick, my Invention of "AN IMPROVED METALLIC
ENGINE TO WORK EITHER BY STEAM OR WATER, WHICH I DENOMINATE 'BODLEY'S
IMPROVED METALLINE ENGINE;"" in which said Letters Patent there is contained
a proviso that if I, the said George Bodley, shall not particularly describe and
ascertain the nature of my said Invention, and in what manner the same is to
be performed, by an instrument in writing under my hand and seal, and causo
the same to be inrolled in His Majesty's High Court of Chancery within
six calendar months next and immediately after the date of the said Letters
Patent, that then the said Letters Patent, and all liberties and advantages
whatsoever thereby granted, shall utterly cease, determine, and become void,
as in and by the same (relation being thereunto had) may more fully and at
large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
George Bodley, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, are particularly described
and ascertained in the plans hereunto annexed, and in the following explanation
thereof, that is to say:-
I fix a wheel or wheels of different descriptions, as will be shewn in the
Drawings, made of iron or wood or any other materials, in a simicircle or
any part of a circle as may be required, which said weel or wheels, simi-
circle or any part of a circle, I fix in an iron vessel or boiler (filled with
water and heated by the fire after it has passed the steam boiler); into the
said simicircle or any part of a circle, having ends fixed to it, I put a quantity
of quicksilver or any other metal or metals fusible in boiling water, and by
means of pipes, to which is fixed a cock or cocks, I introduce either steam
or water through the quicksilver-or any other metal or metals fusible in
boiling water, into the buckets of the said wheel or wheels, near the bottom
of the simicircle or part of a circle; the steam or water immediately displaces
part of the quicksilver or any other metal or metals fusible in boiling water,
and the machine is set in motion. But to prevent the wheel or wheels from
floating, I fix two flys on an arbor at the top edge of the wheel or wheels,
which said flys receive their motion by friction rollers fixed on the same arbor
and running on the rims of the said wheel, or by an addition of a wheel and
pinion, as may be found most eligible. If the machine or engine is driven
by steam, it may be proper to fix centrifugal balls, as is usually fixed to the
common steam engine, to regulate its velocity, but if driven by water it is
not required, but should the fall of water be more than thirty feet, I introduce
shifting buckets or floats in the simicircle or any part of a circle, as will be
shewn in the Drawings.

metal or metals fusible in boiling water.

rollers; D, D, the flys; E, the pinion; F, the wheel that drives the pinion.
Fig. 4 is the section of a wheel entirely covered with quicksilver or any
other metal or metals fusible in boiling water. A, the wheel; B, the part of
a circle; C, C, the friction rollers; D, the level of the quicksilver or other
metals fusible in boiling; E, the pipe.
