the Office of the Commissioners of Patents, with his Petition, on the

1, JOHN LEGGETT BUDDEN, of 48, Fenchurch Street, in the City of London,
Merchant,. do hereby declare the nature of the Invention for "IMPROVEMENTS
IN THE APPLICATION OF STEAM OR HIGHLY RAREFIED GAS OR OTHER AERIFORM FLUID
TO OBTAIN MOTIVE POWER FOR PROPELLING AND OTHER PURPOSES," to be as
follows:-
This Invention has for its object the application of steam, highly rarefied
gas, or other aeriform fluid to the turbine wheel, of small or large size, for
giving rotatory motion to machinery generally, but chiefly for the application of
the principle of the turbine to the construction of screw propellers, as a means
of obtaining power for the purpose of propelling ships or other vessels in water

page_text: by the agency of steam or other aeriform fluid. For this purpose screw
propellers constructed according to this Invention are made with a hollow
"boss" and pipe for the reception of steam, highly rarefied gas, or other
aeriform fluid having "helical" emitting tubes passing or traversing the line
of pitch or thread of the screw both forward and backward, those emitting
backwards to produce forward motion, and vice versa.
For the purpose of producing alternation of action by screw propellers of
this construction, the hollow boss before mentioned is furnished with a con-
centric slide valve, having orifices cut out of it corresponding with the vent
holes or mouths of the "helical" tubes, but by being inferior in length to the
boss itself is capable, by means of rods attached, of opening the vents in either
direction, or of closing them altogether against the emission of steam, the
forward tubes having their mouths at the top and bottom, and the retrograde
at the two sides, or vice versa.
In order to obtain this result and at the same time not to interfere with
the rotatory motion of the propeller, the rods for sliding the valve are attached
to a ring or flange moving or sliding on the screw pipe or shaft, on which at
both sides of the shaft a spanner or square-mouthed claw is placed, in which
the ring or flange revolves without touching it until required to do so for
changing the direction of motion or closing the boss against the further
emission of steam. The motion is changed inside the vessel (after the steam
is cut off by the "stop valve") by means of a rack and pinion adjustment, or
other suitable apparatus.
This turbine screw propeller" revolves in "gudgeons," independently of
any machinery inside; forward in a "gudgeon" in which the steam pipe is
fixed and after in another attached to the iron frame in which the "screw
propeller" revolves, the shaft or axis is fitted with hardened flanges of
sufficient strength to sustain the back and forward pressure of the screw.
The form of screw preferred for the purposes herein set forth is, in the
opinion of the Inventor, the double-threaded screw of the "archimedes" steam
vessel (improved near the boss), as described and recommended by Tredgold,
although other forms may be employed.
Finally, this Invention is not confined to the precise arrangements described,
but is intended to combine the principle of uniting the action of a "turbine"
with a screw propeller for obtaining propulsion by steam or other jets through
the revolution of the screw thus produced. Also for the application of the
principle of the turbine generally to give rotatory motion to machinery by
means of an endless screw attached to the solid part of the shaft prolonged, or
by constructing fly wheels on the turbine principle, through which all waste

page_text: steam may be carried from high-pressure engines of whatever construction;
the force employed being steam or highly rarified gas, or other aeriform
fluid.

of the Cape of Good Hope, upon the condition (amongst others), that I, the said
John Leggett Búdden, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should particularly
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 immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said John Leggett Budden, 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 Juvention has for its object the application of steam, highly rarified gas,
or other aeriform fluid to the turbine wheel, of small or large size, for giving

propellers constructed according to this Invention are made with a hollow

(aeriform fluid, having "helical" emitting tubes passing or traversing the line
of pitch or thread of the screw both forward and backward those emitting

In order to obtain this result, and at the same time not to interfere with the

This turbine screw propeller," revolves in "gudgeons," independently of
any machinery inside formed in a "gudgeon," in which the steam pipe is fixed,
and after in another attached to the iron frame in which the "screw,"
peller revolves; the shaft or axis is fitted with hardened flanges of sufficient
strength to sustain the back and forward pressure of the screw. The form
of screw preferred for the purposes herein set forth is in the opinion of the
Inventor the double threaded screw of the "archimedes," steam vessel (im-
proved near the boss,) as described and recommended by Tredgold, although
other forms may be employed.
Finally, this Invention is not confined to the precise arrangements described,
but is intended to combine the principle of uniting the action of a "turbine,"
with a screw propeller for obtaining propulsion by steam or other jets through
the revolution of the screw thus produced; also, for the application of the

page_text: principle of the turbine generally to give rotatory motion to machinery by
means of an endless screw attached to the solid part of the shaft prolonged,
or by constructing fly wheels on the turbine principle through which all
waste steam may be carried from high-pressure engines of whatever con-
struction, the force employed being steam or highly rarified gas or other
aeriform fluid.
And in order that the Invention may be most fully understood and readily
practised, I will proceed to describe the Drawing hereunto annexed.
DESCRIPTION OF THE DRAWING.
The Drawing shows the application of the Invention to the stern of a vessel'
similar to that of the "archimedes," partly in section and partly in elevation,
with the screw apparatus also partly in elevation and partly in section. A,
shows the hollow "boss," upon which the screw is mounted; B is the slide
valve; C, C, are the steam emitting orifices to propel the vessel forward; and
C1, C1, the orifices for propelling the vessel "astern"; D is the claw spanner
(near side); E, the flange ring for moving the slide valve; F, F, gudgeons for
screw shaft; G, steam pipe from boiler; H, stop valve; I, safety valve; and
K, high-pressure boiler. From the previous description it will be evident to a
competent mechanic that the Invention may be readily applied for the purpose
of obtaining motive power by giving rotatory motion to suitably constructed
wheels or turbines by means of jets of steam or other highly rarified gas or
other aeriform fluid as herein described.
In witness whereof, I, the said John Leggett Budden, have hereunto
set my hand and seal this Twenty-first day of March, in the year of our
Lord One thousand eight hundred and sixty-one.
