Ulverstone, in the County of Lancaster, Engineer, for the In-
vention of "IMPROVEMENTS IN LOCOMOTIVE ENGINES FOR NARROW GUAGE
RAILWAYS."
Sealed the 20th June 1871, and dated the 2nd January 1871.
PROVISIONAL SPECIFICATION left by the said John Barraclough Fell
at the Office of the Commissioners of Patents, with his Petition, on
the 2nd January 1871.
I, JOHN BARRACLOUGH FELL, of Spark Bridge, near Ulverstone, in
the County of Lancaster, Engineer, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN LOCOMOTIVE ENGINES FOR NARROW
GUAGE RAILWAYS," to be as follows:-
.
The accompanying Drawing illustrates the nature of my Invention,
Fig. 1 being a side elevation.
My Invention relates to an improved form of locomotive engine for
working on narrow guage railways, being improvements upon those

page_text: described in the Specification of my Patent, No. 766, in the year of our
Lord One thousand eight hundred and sixty-eight.
Instead of using two boilers as described in the Specification of my
said Patent, my Invention consists in using only one boiler (a, b,) placed
above the rails, but brought down nearly to their level by the leading
wheels being placed in front of. the smoke box, the trailing wheels behind
the fire-box (6), and a third pair of wheels when used being placed under
the barrel of the boiler. The side frames (9) are of the usual form, but
inverted, the horn plates projecting upwards, the principal part of the
weight of the frames being near or below the level of the rails (as shown)
and the water tanks (j) (one on each side of the engine) are attached
to the side frames. Horizontal guide wheels (h) are used to act upon
the guide rails (¹) as an additional protection against getting off the
rails.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
4
filed by the said John Barraclough Fell in the Great Seal Patent
Office on the 21st June 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
BARRACLOUGH FELL, of Sparke Bridge, near Ulverstone, in the County
of Lancaster, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Second day of January, in the year of our
Lord One thousand. eight hundred and seventy-one, in the thirty-fourth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said John Barraclough Fell, Her special license
that I, the said John Barraclough Fell, my executors, administrators,
and assigns, or such others as I, the said John Barraclough. Fell, 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 LOCOMOTIVE ENGINES FOR NARROW GAUGE RAILWAYS," upon the condition
(amongst others) that I, the said John Barraclough Fell, by. an
Instrument in writing under my hand and seal, should particularly

page_text: 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 Barraclough Fell, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained, in
and by the following statement (and accompanying Drawings), that is
to say :-
My Invention relates to an improved form of locomotive engine for
working on narrow gauge railways, being improvements upon those.
described in the. Specification of my Patent, No. 766, "A.D. 1868."
The object of my Invention being to use only one boiler; and yet bring
down the centre of gravity of the engine lower than in those of ordinary
construction, whereby greater, steadiness and stability is obtained when
running.
Instead of using two boilers as described in the Specification of my said
Patent my Invention consists in using only one boiler placed above the
carrying rails, but brought down nearly to their level by the leading wheels
being placed in front of the smoke box, the trailing wheels behind the
fire-box, and a third or more pairs of wheels when desired being placed
under the barrel of the boiler. The side frames are of the usual form,
but inverted, the horn plates projecting upwards, the principal part
of the weight of the frames being near or below the level of the carrying
rails. The water tanks (one on each side of the engine) are attached to.
the side frames; guide wheels on vertical axles are used to act upon the
guide rails as an additional protection against getting off the rails, and
also (being equivalent to an extension of the gauge), to give increased
steadiness and stability to the engine.
My improvements are illustrated by Fig. 1 a side elevation; Fig. 2 a
view of the smoke box end; Fig. 3 a view of the fire-box end; and
Fig. 4 a plan section.
a, the barrel of the boiler; a¹, smoke box; a³, fire-box; b, leading
wheels in front of the smoke box; 61, trailing wheels behind the fire-
box; 6, the middle wheels when used. The side frames (c) of the
engine are inverted with the horn plates upwards, as shown; d, are
the tanks on each side of the engine formed on the side frames as shown;
e are the carrying rails; f, the guide rails, and g are guide wheels on

page_text: vertical axles working in bearings secured to the side frames. In the
engine illustrated inside cylinders are shown (see Figs. 1 and 4), but
outside cylinders may be used placed above or partly or altogether below
the level of the carrying rails, and the engine may be used either with
the tanks shewn or with a tender.
I have now particularly described the nature of my Invention, and
the mode of carrying it into effect, and claim as my Invention,―
Firstly. The combination and arrangement of the parts of a locomotive
to run on a pair of rails with the carrying wheels placed in front of
the smoke box, and behind the fire-box (a third or more pairs of wheels
when desired being placed under the barrel of the boiler), and having
inverted side frames, substantially as herein-before described and illus-
trated by the Drawings.
Also the said combination and arrangement of parts, when combined
with guide wheels (g), or with tanks (d) on the side frames, substantially
as herein-before described and illustrated by the Drawings.
In witness whereof, I, the said John Barraclough Fell, have here-
unto set my hand and seal, this Twentieth day of June, in the
year of our Lord One thousand eight hundred and seventy-one.
