Year: 1861

page_text: LETTERS PATENT to Alfred Fernandez Yarrow, Engineer, of Arundel
Square, Barnsbury, and James Bracebridge Hilditch, Gentleman, of
Barnsbury Villas, both in the County of Middlesex, for the Invention of
"IMPROVEMENTS IN LOCOMOTIVE STEAM CARRIAGES FOR COMMON ROADS."
Sealed the 13th May 1862, and dated the 22nd November 1861.
PROVISIONAL SPECIFICATION left by the said Alfred Fernandez Yarrow
and James Bracebridge Hilditch at the Office of the Commissioners of
Patents, with their. Petition, on the 22nd November 1861.
We, ALFRED FERNANDEZ YARROW, Engineer, of Arundel Square,. Barnsbury,
and JAMES BRACEBRIDGE HILDITCH, Gentleman, of Barnsbury Villas, both in
the County of Middlesex, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN LOCOMOTIVE STEAM CARRIAGES FOR COMMON ROADS,"
to be as follows:-
This Invention has for its object improvements in locomotive steam.carriages
for common roads, and consists of an arrangement of outside cylinders, the
connecting rod being coupled on to the crank of the driving, axle. The cylinders
are bolted to the framing,. which runs the whole length of the carriage. The
bearings of the axle are supported by springs. On the inside of the bearings
are the driving wheels, and on the outside is fixed a crank to which the con-
necting rod is coupled, or the driving wheels and crank may be both placed
outside the bearings. To each bearing is attached one or more links, the other
extremities of which are connected to the main framing of the carriage, or to
the steam cylinder itself, by which means the proper distance between the
driving axle and cylinder is maintained, and also play allowed to the springs.
The second part of our Invention consists in. the general arrangement of the

page_text: said steam carriage. We employ a vertical tubular boiler, which is placed at
the back of the main driving axle, and between the driving wheels. The
seats for passengers and luggage are arranged upon the framing between the
boiler and the fore part of the carriage, where suitable steering gear is also
provided. At the back part of the carriage behind the boiler, room for the
stoker is provided, as also coal bunkers and water tanks, &c. The eccentrics
are keyed on the driving axle between the boiler and the framing of the
carriage. Rods may be continued from the reversing gear and steam cock to
the front part of the carriage, so as to place the carriage under the control of
the steerer. If a horizontal boiler is used, it is placed as nearly over the
driving axle as convenient.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Alfred Fernandez Yarrow and James Bracebridge Hilditch
in the Great Seal Patent Office on the 22nd May 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ALFRED
FERNANDEZ YARROW, Engineer, of Arundel Square, Barnsbury, and JAMES
BRACEBRIDGE HILDITCH, Gentleman, of Barnsbury Villas, Barnsbury, London,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of November, in the year of our
Lord One thousand eight hundred and sixty-one, in the twenty-fifth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said Alfred Fernandez Yarrow and James Bracebridge Hilditch, Her
special licence that we, the said Alfred Fernandez Yarrow and James
Bracebridge Hilditch, our executors, administrators, and assigns, or .such
others as we, the said Alfred Fernandez Yarrow-and-James-Bracebridgo-
Hilditch, our 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 STEAM CARRIAGES FOR COMMON ROADS," upon the condition (amongst
others) that we, the said Alfred Fernandez.Yarrow and James Bracebridge
Hilditch, our executors or administrators, by an instrument in writing under
our, or their, or one of their hands and scals, should particularly describe
and ascertain the nature of the said Invention, and in what manner the

page_text: 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 we, the said Alfred Fernandez Yarrow and James.
Bracebridge Hilditch, do hereby declare the nature of our said Invention,
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement, reference being had to the
Drawings hereunto annexed, and to the letters and figures marked thereon
(that is to say):
'Our Invention has for its object improvements in locomotive steam carriages
for common roads, and consists of an arrangement of outside cylinders
(cylinders arranged to work outside cranks, being generally known as outside
cylinders), the connecting rod being coupled on to the crank of the driving
axle. The cylinders are bolted to the framing, which runs the whole length.
of the carriage. The bearings of the axle are supported by springs. On the
inside of the bearings are the driving wheels, and on the outside is fixed a
crank, to which the connecting rod is coupled; or the driving wheels and
crank may be both placed outside the bearings. To each bearing is attached
one or more links, the other extremities of which are connected to the main
framing of the carriage, or to the steam cylinder itself, by which means the
proper distance between the driving axle and cylinder is maintained, and also
play allowed to the springs.
The second part of our Invention consists in the general arrangement of the
said steam carriage. We employ a vertical tubular boiler, which is placed at
the back of the main driving axle, and between the driving wheels. . The
seats for passengers and luggage are arranged upon the framing, between the
boiler and the fore part of the carriage, where suitable steering gear is also
provided. At the back part of the carriage behind the boiler, room for the
stoker is provided, as also coal bunkers and water tanks, etc. The eccentrics
are keyed on the driving axle between the boiler and the framing of the
carriage. Rods may be continued from the reversing gear and steam cock to
the front part of the carriage, so as to place the carriage under the control of
the steerer. If a horizontal boiler is used, it is placed as nearly over the
driving axle as convenient.
And in order that our said Invention may be fully understood, we will now
proceed more particularly to describe the same, and for that purpose we shall
refer to the Drawings hereunto annexed.
Fig. 1 represents an elevation, and Fig: 2 a plan;
reference indicating corresponding-parts-in-both.
same letters of

page_text: a and a' are the two main beams of the carriage; to these beams are bolted
the foundation plates c and c', to which the steam cylinders 6 and 6' are firmly
attached. Upon c and c¹ are the standards m and m', to which one end of
the links and f are connected. To the other ends of ƒ and' fare attached
the bearings, in which the driving axle revolves at 9 and g¹. These bearings
support the springs, which themselves carry the main frames a and a¹. On
the outside of g and g', and fixed to the driving axle, are the cranks e and e',
to which the connecting rods are coupled. On the inside of G and G are the
driving wheels d and d', both of which may be keyed on the axle. k is the
boiler, at the back of it is the tender 7; h and h¹ are the front wheels, they
are outside a and a', and are wider gauge than the driving wheels, in order to
give the required stability. The position of the seats is distinctly shown in
Fig. 1, and is represented by the dotted lines in Fig. 2. The engines may be
placed on the reverse side of the driving axle to that shown in the Drawings.
The valve gear and other parts of the engines are arranged according to some
well-known method. A tank is placed under the front seats.
Having thus described the nature of our Invention, and the manner of
performing the same, we would have it understood that we do not claim any
of the mechanical parts separately, nor do we confine ourselves to the details;
but what we claim is,―
Firstly, the combination and arrangement of outside cylinders, framing,
driving wheels, and links for maintaining the proper position of the axle, as
herein-before described.
And, secondly, the arrangement of the framing of the carriage with the
seats, wheels, and boiler, as herein-before described.
In witness whereof, we, the said Alfred Fernandez Yarrow and James
Bracebridge Hilditch, have hereunto set our hands and seals, this
Twenty-second day of May, in the year of our Lord One thousand
eight-hundred-and-sixty-two-
