Year: 1857

page_text: LETTERS PATENT to Richard Archibald Brooman, of 166, Fleet Street, in
the City of London, E. C., Editor of the Mechanics' Magazine and
Patent Agent, for the Invention of "IMPROVEMENTS IN MOTIVE POWER
ENGINES." A communication from P. and L. Larochette, of Paris.
PROVISIONAL SPECIFICATION left by the said Richard Archibald Brooman
at the Office of the Commissioners of Patents, with his Petition, on the
27th July 1857.
I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, E. C., Editor of the Mechanics' Magazine and Patent Agent, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN MOTIVE
POWER ENGINES," (communicated to me by P. & L. Larochette, of Paris,
foreigners residing abroad,) to be as follows:-
The Invention consists in constructing motive-power engines in the following
manner-In each of several tubes or cylinders is placed a vane or a set of
vanes, or other contrivance for receiving notion from a fluid in motion, and
for communicating the said motion to a central shaft, and these several tubes
or cylinders are so combined that water, steam, air, or any other suitable fluid
may pass successively through the whole of them, impressing a rotary motion
upon each of their central shafts, or upon one common shaft, from which
shafts or shaft the motion is transferred if necessary by any suitable arrange-

page_text: ment of gearing or otherwise to a driving shaft, by which any description of
machinery or apparatus which requires the application of motive power may
be driven.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Archibald Brooman, in the Great Seal Patent Office
on the 27th January 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, 1, RICHARD
ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of London, E.C.,
Editor of the Mechanics' Magazine and Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by ler Letters
Patent, bearing date the Twenty-seventh day of July, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Richard Archibald Broonian, Her special licence that I, the said Richard
Archibald Brooman, my executors, administrators, and assigns, or such
others as I, the said Richard Archibald Brooman, my executors, adminis-
trators, 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 MOTIVE POWER ENGINES," (communicated to
me by P. and L. Larochette, of Paris,) upon the condition (amongst others)
that I, the said Richard Archibald Brooman, my executors or administra-
tors, 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 Richard Archibald Brooman, do hereby
declare the nature of the said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement thereof, reference being had to the Drawings hereunto
annexed, that is to say :-
The Invention consists in constructing motive-power engines in the following
manner: In each of several tubes or cylinders is placed a vane or a set of
vanes, or other contrivance for receiving motion from a fluid in motion, and

page_text: for communicating the said motion to a central shaft; and these several tubes
or cylinders are so combined that water, steam, air, or any other suitable fluid
may pass successively through the whole of them, impressing a rotary motion
upon cach of their central shafts, or upon one common shaft, from which
shafts or shaft the motion is transferred if necessary by any suitable arrange-
ment of gearing or otherwise to a driving shaft, by which any description of
machinery or apparatus which requires the application of motive power may
be driven.
•
In the Sheet of Drawings hereunto annexed are represented two arrange-
ments of apparatus by means of which the inventors propose to carry their
Invention into effect. Figures 1 and 2 are respectively a sectional elevation
and a plan of an apparatus intended to be worked by an artificial fall of water.
It is composed mainly of a series of cylinders arranged in a circle with their
axes vertical. These cylinders have fitted within them wheels or turbines, the
rotary motion of which is transmitted through an upright shaft and a pinion
at its upper extremity to a common wheel, the shaft of which is thereby put in
motion, and from this shaft power may be led away as required. If water be
forced by the piston a of the pump 6, up through the pipe c into the cylinder
d, it will fall upon the upper plate or crown e of the wheel or turbine e¹, and
accumulating above it will soon commence to pass through it, imparting to it
a rotary motion. This wheel or turbine being fixed to the shaft f will con-
sequently impart to it a rotary motion, and through it convey a similar motion
to the pinion 9 and to the wheel h, which is in gear with it. To increase the
effect the water which has actuated the first wheel or turbine is forced by the
piston a to pass through the pipe into a second cylinder d', in which is a
second wheel or turbine where it acts as in the first, and so on throughout the
whole series of cylinders. The power of the whole of the wheels or turbines
is collected in the common wheel h, which transmits it to the central shaft i,
from which it is taken as required.
Figure 3 is a sectional elevation of an apparatus intended to be worked by
a natural fall of water. In this apparatus the wheels or turbines are disposed
vertically above each other, and communicate their motion immediately to a
common shaft. The feed water is supplied by the channel m, and after
passing through the sluice n enters the reservoir o, whence it flows into the
first wheel or turbine, which, as in the former apparatus, is composed of a
fixed part e, and a moveable part el. After exerting a rotary action upon this
first wheel or turbine it descends successively and with like effect through a
second, third, and other remaining and similar wheels or turbines, and finally
passes away by a channel o'. The power of the whole of the several wheels

page_text: or turbines is concentrated upon the central shaft i, from which it may be led
away in any suitable manner and for any required purpose.
The apparatuses above described may be modified in many ways without
departing from the principle of the Invention.
And having now described the nature of the said Invention, and in what
manner the same is to be performed, I declare that I claim the construction
of motive-power engines, as herein-before described.
In witness whereof, I, the said Richard Archibald Brooman, have here-
unto set my hand and seal, this Twenty-seventh day of January, One
thousand eight hundred and fifty-eight.
