IMPROVEMENTS IN MACHINERY FOR OBTAINING MOTIVE POWER BY MEANS OF STEAM
Year: 1863

page_text: LETTERS PATENT to William Verran, of Penryn, Cornwall, Mechanical
Engineer, for the Invention of "IMPROVEMENTS IN MACHINERY FOR
OBTAINING MOTIVE POWER BY MEANS OF STEAM."
Sealed the 19th April 1864, and dated the 30th October 1863.
PROVISIONAL SPECIFICATION left by the said William Verran at the
Office of the Commissioners of Patents, with his Petition, on the 30th
October 1863.
I, WILLIAM VERRAN, of Penryn, Cornwall, Mechanical Engineer, do
hereby declare the nature of the Invention for "IMPROVEMENTS IN MACHINERY
FOR OBTAINING MOTIVE POWER BY MEANS OF STEAM," to be as follows:-
This Invention has for its object improvements in machinery for obtaining
motive power by means of steam. For this purpose I introduce steam from
a boiler into a pipe or pipes forming either the outer rim of a fixed cylinder
or fixed immediately within the outer rim of a cylinder. From this pipe or
these pipes I cause the steam to issue through jets or apertures on the inside
of the cylinder, and the jets or apertures are inclined at an angle to the radius
of the cylinder. Within the cylinder I cause a wheel to work having blades
or paddles or chambers upon its circumference; upon these blades or paddles
or into the chambers the steam is thrown immediately upon issuing from the
jets or apertures, above described, and the wheel is thus caused to revolve.
The axle of the wheel is attached to it, and passes through the sides of the fixed
cylinder; it is fitted with gear outside the cylinder for driving machinery.
According to another arrangement I introduce steam through a hollow
shaft or axle into a revolving cylinder working within a fixed cylinder and
concentric with it. Upon the outer rim of the revolving cylinder I place jets
or apertures through which the steam issues at an angle; I also place blades

page_text: or chambers of resistance upon the inside of the rim of the outer cylinder,
against which the steam is thrown from the jets or apertures in the wheel or
cylinder, thus causing the wheel to revolve. The axle of the revolving wheel
is fitted, as before, with gear outside the cylinder for the purpose of driving
machinery.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Verran in the Great Seal Patent Office on the
28th April 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
VERRAN, of Penryn, Cornwall, Mechanical Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of October, in the year of our
Lord One thousand eight hundred and sixty-three, in the twenty-seventh
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said William Verran, Her special licence that I, the
said William Verran, my executors, administrators, and assigns, or such
others as I, the said William Verran, my executors, administrators, and
assigns, should at any time agree with, and no others, from time to time
and at all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United Kingdom of
Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "IMPROVEMENTS IN MACHINERY FOR OBTAINING MOTIVE POWER
BY MEANS OF STEAM," upon the condition (amongst others) that I, the
said William Verran, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should par-
ticularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Verran, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say :-
This Invention has for its object improvements in machinery for obtaining
motive power by means of steam. For this purpose I introduce steam from
a boiler into a pipe or pipes forming either the outer rim of a fixed cylinder
or fixed immediately within the outer rim of a cylinder. From this pipe or

page_text: these pipes I cause the steam to issue through jets or apertures on the inside
of the cylinder, and the jets or apertures are inclined at an angle to the radius
of the cylinder. Within the cylinder I cause a wheel to work having blades
or paddles or chambers upon its circumference; upon these blades or paddles
or into the chambers the steam is thrown immediately upon issuing from the
jets or apertures above described, and the wheel is thus caused to revolve.
The axle of the wheel is attached to it, and passes through the sides of the
fixed cylinder; it is fitted with gear outside the cylinder for driving
machinery.
According to another arrangement I introduce steam through a hollow
shaft or axle into a revolving cylinder working within a fixed cylinder and
concentric with it. Upon the outer rim of the revolving cylinder I place jets
or apertures through which the steam issues at an angle; I also place blades
or chambers of resistance upon the inside of the rim of the outer cylinder
against which the steam is thrown from the jets or apertures in the wheel or
cylinder, thus causing the wheel to revolve. The axle of the revolving wheel
is fitted as before with gear outside the cylinder for the purpose of driving
machinery.

One thousand eight hundred and sixty-four.
