Year: 1809

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
LANE, of Shelton, in the Parish of Stoke-upon-Trent, in the County of
Stafford, Schoolmaster, send greeting.
WHEREAS His present Majesty King George the Third, in and by His
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Ninth day of August last, for Himself, His heirs and successors,
did give and grant unto me, the said Edward Lane, His especial licence, full
power, sole privilege and authority, that I, the said Edward Lane, my exors,
adñiors, 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, the said
Edward Lane, my exors, admors, or assigns, should at any time agree with,
and no others, from time to time and at all times thereafter 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, my
Invention of "AN IMPROVED ROTATIVE ENGINE OR MACHINE TO BE WORKED BY
THE POWER OF STEAM, FOR RAISING WATER, GRINDING CORN, AND VARIOUS OTHER
USEFUL PURPOSES;" in which said Letters Patent there is contained a proviso
obliging me, the said Edward Lane, by an instrument in writing under my
my said
hand and seal, particularly to describe and ascertain the nature of
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 two
calendar months next and immediately after the date of the said recited
Letters Patent, as in and by the same, reference being thereto had, will more
fully appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Edward Lane, do hereby describe and ascertain the nature of my said Inven-
tion, and in what manner the same is to be performed and operate by the
Plans or Drawings hereto annexed, and in the following description thereof,
(that is to say): :-
My Invention-consists,-as- represented by the Drawings here annexed, of
giving rotation to a wheel by conveying steam into its axle or shaft, and by
passages from thence to the circumference of the wheel, by the opening of
gates or valves which are hung at the extreme of the wheel, and with certain
other machinery to be hereafter described, and which are operated upon by
the expansive force of the steam. A wheel so impelled to rotation may be
placed vertically, horizontally, or obliquely, whichever is found most conve-
nient, and may be employed as a moving power to any machine with little
expence and considerable effects
Figure 1 represents the steam wheel A, placed with its axle horizontally,
and moving in its bearing B conventrically to the arch C, C, or segment of
a cylinder, one end of which is stopped close to the wheel A, by the bridge
or cover D, and the other end of the arch C is left open for, the escape of
the steam, as at E, into the atmosphere.. In each of the arnis of the wheel
A, there is a passage F, F, F, for the steam to extend to the periphery of the
wheel by the lifting of the gates G, which are shown in Figure 2 and 5,
which move correctly in the arch CC, one of which gates must always be
extended by the expansive force of the steam contained between the stop of
the arch D and the face of the gate G; by a constant supply of steam it will
be clearly seen that the alternate operation of the gates G-will ensue, and
the-steam wheel be thereby kept in constant rotation with a force proportioned
to the area of the gate, the diameter of the steam wheel, and the expansive
force of the steam acting on the gate. The steam may be conveyed into the
shaft of the steam wheel A from the boiler wherein it is generated by any of
the common means used for the conducting of steam; and the respective
parts of my rotatory steam engine which required to be made steam-tight
may be done by any of the usual modes employed for that purpose by all
skilful engineers.
Figure 6 is a view of the steam wheel A, standing with its shaft or axle
in a verticle direction, and révolving concentrically in the cylinder B, B,
instead of the arch C, C, as in Figure 1; and instead of the steam entering
in at the shaft as in Figure 1, I here, introduce it upon the extreme of the
wheel A, through the perforation or pipe C upon the gate G, and the steam
so introduced is confined betweeen the bridge D and the face of the gate G,

page_text: which forces round the wheel A till the gate G comes opposite to the exit
pipe E; by this time the opposite or other gate G has passed the bridge D,
and the expansive force of the steam is acting upon it, as on the former gate,
and thus the rotation is constantly kept up. The gates G, G, are made to
shut the instant they approach the bridge D, and again are thrown open
directly they pass the bridge by any suitable machinery for that purpose.
per-
Figure 7 is a section of an engine, as shewn in Figure 6, with its shaft
placed perpendicularly, and the stuffing boxes and flanches necessary to the
fect performance of this engine. It is obvious that this engine may be worked
not only as a high-pressure engine, but it is also capable of being used as a
condensing engine, by the application of the air and condensing pumps, and it
is in every respect capable of all the variety of object to which steam engines
are generally employed.
In witness whereof, I have hereunto set my hand and seal, this Ninth

AND BE IT REMEMBERED, that on the Ninth day of October, in the
year of our Lord 1809, the aforesaid Edward Lane came before our said
Lord the King in His Chancery, and acknowledged the Specification aforesaid,
and all and every thing therein contained and specified, in form above written.
And also the Specification aforesaid was stampt according to the tenor of the
Statute made for that purpose.
