In- PROVEMENTS IN LOCOMOTIVE ENGINES AND CARRIAGES FOR RAILWAYS
Year: 1869

page_text: LETTERS PATENT to Francis William Fox, of Atlas Iron Works, near
Bristol, in the County of Gloucester, for the Invention of "In-
PROVEMENTS IN LOCOMOTIVE ENGINES AND CARRIAGES FOR RAILWAYS."
Scaled the 14th September 1869, and dated the 19th March 1869.
PROVISIONAL SPECIFICATION left by the said Francis William Fox
at the Office of the Commissioners of Patents, with his Petition, on
the 19th March 1869.
I, FRANCIS WILLIAM Fox, of Atlas Iron Works, near Bristol, in the
County of Gloucester, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN LOCOMOTIVE ENGINES AND CARRIAGES FOR RAILWAYS,"
to be as follows:-
My Invention has for its object to dispense with the bogic trucks for
railway engines and carriages, and is especially applicable to combined
locomotives and carriages, or to coupled locomotives. For this purpose
I connect the contiguous ends of the framework of the engines or
carriages, or engine and carriages combined, by means of springs or
clastic rings inserted in both or one of the outer frames, at each side

page_text: thereof, and in the centre line of the engine and carriages, midway
between the side connections I pass a bolt or bolts through the two
frames in such a manner that they can freely turn laterally upon such
bolt or bolts while the two frames by the above described lateral con-
nection form practically one, admitting of no other relative motion
beyond such lateral motion round the connecting bolt. The clastic
rings may for this purpose be made cither flat or dished out with a
cup-shaped recess in the centre. The frame of the one carriage or
engine being thus supported by that of the other engine or carriage to
which it is connected, the ordinary pair of wheels under the end of the
one carriage or engine so connected are dispensed with, and in place
thereof I provide a support or wheel or wheels capable of being raised
from and lowered upon the rails by any suitable known mechanical
contrivance so as to serve as a support for that end of the carriage or
engine when disconnected from the other carriage..
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Francis William Fox in the Great Seal Patent
Office on the 17th September 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FRANCIS
WILLIAM Fox, of Atlas Iron Works, near Bristol, in the County of
Gloucester, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of March, in the year
of our Lord One thousand eight hundred and sixty-nine, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Francis William Fox, Her special
Licence that I, the said Francis William Fox, my executors, admi-
nistrators, and assigns, or such others as I, the said Francis William
Fox, 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 AND CARRIAGES FOR
RAILWAYS,' upon the condition (amongst others) that I, the said

page_text: Francis William Fox, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said In-
vention, 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 Francis William Fox, 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
accompanying Sheet of Drawings, and to the figures and letters marked
thereon, that is to say :-
My Invention has for its object to dispense with the bogie trucks for
railway engines and carriages, and is especially applicable to combined
locomotives and carriages, or to coupled locomotives. For this purpose
I connect the contiguous ends of the framework of the engines or
carriages, or engine and carriages combined, by means of springs or
elastic rings inserted in both or one of the outer frames, at each side
thereof, and in the centre line of the engine and carriages, midway
between the side connections, I pass a bolt or bolts through the two
frames in such a manner that they can freely turn laterally upon such
bolt or bolts, while the two frames by the above described lateral con-
nection form practically one, admitting of no other relative motion
beyond such lateral motion round the connecting bolt. The elastic
rings may for this purpose be made either flat or dished out with a
cup-shaped recess in the centre. The frame of the one carriage or
engine being thus supported by that of the other engine or carriage
to which it is connected the ordinary pair of wheels under the end of
the one carriage or engine so connected are dispensed with, and in place
thereof I provide a support or wheel or wheels capable of being raised
from and lowered upon the rails by any suitable known mechanical
contrivance so as to serve as a support for that end of the carriage or
engine when disconnected from the other carriage.
Having thus set forth the nature of my Invention, I will now proceed
more particularly to describe the manner of performing the same, for
which purpose I shall refer to the accompanying Sheet of Drawings.
Figure 1 shews a part plan and part sectional plan, and Figure 2

page_text: shews a side clevation of my improved combined engine and carriage,
and Figures 3 and 4 shew enlarged details thereof. Similar letters of
reference indicate similar parts in each of the Figures.
The frame of the locomotive engine A is formed with a box-shaped
extension B at the end nearest the carriage C, such extension being
constructed as shewn more clearly in the enlarged cross section thereof
at Figure 4. Inside this box framing B are fixed on either side
sockets D containing india-rubber or metal springs E; upon these
springs rest projecting parts F of the under framing of the carriage C,
which carriage is provided with wheels G only at the farther end and
is consequently supported at this end entirely by the engine A through
the mediation of the said springs E. A loop H fixed centrally to the
carriage frame also projects into the box framing B, to which it is
secured by means of a linch pin I passing right through. By this
arrangement it will be seen that the carriage and engine are capable
of turning freely on such central pin, while at the same time they
form practically one combined engine and carriage. In order to support
the carriage at this connected end when disconnected from the engine
it is provided with two small wheels K carried on the ends of levers L
fixed on a shaft M capable of being turned by means of a lever N and
screw spindle O actuated by hand wheel P, so as to keep the wheels
raised from the rails under ordinary circumstances, but to lower them
on to the rails when the carriage C is disconnected from the engine. Or,
the wheels may be carried separately by bell-crank levers Q, as at
Figure 3, turning on a fulcrum in the bracket R and actuated by the
screw S suspended from a pin T on the under framing of the carriage.
It will be evident that my Invention is equally applicable for con-
necting two carriages so as to form one jointed carriage thereof, as also
to coupled locomotives.
Having thus described the nature of my Invention, and in what
manner the same is to be performed, I wish it to be understood that I
do not limit myself to the precise details of the arrangement thereof as
shewn on the accompanying Drawing, as these may be variously modified
without departing from the nature of my Invention; but what I claim
under the herein-before in part recited Letters Patent is,-
First. Supporting the one end of a carriage or locomotive engine by the
contiguous end of another carriage or locomotive engine, substantially
as and for the purposes hercin-before described.

page_text: Second. Providing the supported end of such carriage or locomotive
engine with one or more wheels capable of being raised from and lowered
to the ground, substantially as described.
In witness whereof, I, the said Francis William Fox, have here-
unto set my hand and seal, this Fifteenth day of September,
in the year of our Lord One thousand eight hundred and sixty-
nine.
Witness to the signature of
Fra. W. Fox, 15th Sep'.
