page_text: LETTERS PATENT to James Broadley, of Bradford, in the County of
York, Mechanic, Copartner with Jonathan Thornton, Richinson
Newell, and John Vanston, under the Style or Firm of James
Broadley and Company, Mechanical Engineers, for the Invention
of "IMPROVED MECHANICAL ARRANGEMENTS FOR COUPLING AND UNCOUPLING
PROVISIONAL SPECIFICATION left by the said James Broadley at the
Office of the Commissioners of Patents, with his Petition, on the
8th November 1870.
I, JAMES BROADLEY, of Bradford, in the County of York, Mechanic,
Copartner with Jonathan Thornton, Richinson Newell, and John
Vanston, under the Style or Firm of James Broadley and Company,
Mechanical Engineers, do hereby declare the nature of the said
Invention for "IMPROVED MECHANICAL ARRANGEMENTS FOR COUPLING AND
UNCOUPLING RAILWAY LOCOMOTIVES, CARRIAGES, TRUCKS, AND VEHICLES," to be
as follows:
These arrangements consist of a sliding shaft or bar working in
suitable bearings secured to the ends of the carriage or vehicle at nearly

page_text: the same position as the usual coupling chain arrangements, which
can be left attached to the carriage or vehicle, & may be made use of
when two carriages are to be coupled, one of which is not provided
with my coupling arrangements. This sliding shaft or bar has a bolt
connected thereto, which bolt is made to work in an orifice provided
for it in the side of a socket or guide secured to the carriage or vehicle,
a slotted coupling lever is also secured to the carriage or vehicle to
which it is attached by a joint, so that it may be lifted up out of the
way and secured by a catch in the sliding shaft when the carriage or
vehicle unprovided with my arrangements is to be coupled. This
coupling slotted lever is when two carriages or vehicles are brought
together for coupling down in its ordinary position, & thereby
inserted in the socket or guides above mentioned by simply bringing
the two carriages or vehicles together and then the sliding shaft can be
actuated by handling its end from the side of the carriage without
going between the carriages, and the uncoupling is effected by a similar
though reverse action.
Lever arrangements might be adopted to enable the guard or
SPECIFICATION in pursuance of the conditions of the Letter's. Patent,
filed by the said James Broadley in the Great Seal Patent Office on
the 8th May 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
BROADLEY, of Bradford, in the County of York, Mechanic, at the time
of applying for the Letters Patent herein referred to Copartner with
Jonathan Thornton, Richinson Newell, and John Vanston, and owing to
the withdrawal of the said John Vanston, now Copartner with Jonathan
Thornton and Richinson Newell, under the Style or Firm of James
Broadley and Company, Mechanical Engineers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighth day of November, in the year
of our Lord One thousand eight hundred and seventy, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said James Broadley, Her special licence
that I, the said James Broadley, my executors, administrators, and

page_text: assigns, or such others as I, the said James Broadley, 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 "IMPROVED MECHANICAL
ARRANGEMENTS FOR COUPLING AND UNCOUPLING RAILWAY LOCOMOTIVES, CARRIAGES,.
TRUCKS, AND VEHICLES," upon the condition (amongst others) that I, the
said James Broadley, 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 James Broadley, 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 :-
•
These mechanical arrangements consist of a sliding shaft or bar
working in suitable bearings secured to the ends of the carriage or
vehicle at a position somewhat above the usual coupling chain arrange-
ment (which can be left attached to the carriage or vehicle,
and may
be
made use of when two carriages are to be coupled, one of which is not
provided with my coupling arrangements). This sliding shaft or bar
has a bolt connected thereto, which bolt is made to work in an orifice
provided for it in the sides of a socket or guides secured to the carriage
or vehicle. A slotted coupling lever is also secured to the carriage or
vebicle, to which it is attached by a joint, so that it may be lifted up
out of the way and secured by a catch on the sliding shaft when a
carriage or vehicle unprovided with my arrangements is to be coupled
in the ordinary way. This coupling slotted lever is, when two carriages
or vehicles are brought together for coupling down in its ordinary
position, and is inserted in the socket or guides above mentioned by
simply bringing the two carriages or vehicles together, and then the
sliding shaft can be actuated so as to couple the carriages by handling
its end from the side of the carriage without going between the carriages
and the uncoupling can be effected by a similar though reverse action.

parts of two railway trucks or carriages with my Invention applied
thereto.
Fig. 4, plan view showing a modification of the arrangements exhibited
in Figs. 1, 2, 3; Fig. 5, sectional view of parts of two trucks or
carriages.
A denotes the sliding shaft or bar herein-before referred to, which is
secured (free to move) to the end of the railway truck or carriage by
the straps B and bracket B', the straps having an orifice and the bracket
a bearing socket, through which the sliding shaft works. C is the bolt
depending from the said sliding shaft, which works through an orifice
provided for that purpose in the side of the socket or guides D, D, (for
the reception of coupling lever G herein-after referred to,) one of which
is shown in the Drawing with the usual coupling hook E secured thereto.
One of the parts marked D of the guide block D, D, forms one bracket,
and F forms another for the bearings of a pin, whereby the coupling
lever G is secured to the truck or carriage, free to be lifted up, and
secured by sliding the bar A, so that the catch H, fixed in the sliding
shaft, as shown, is brought before it, whereby the coupling lever can be
kept out of the way when the truck or carriage is brought opposite
another truck or carriage not provided with my coupling arrangements,
or it may be convenient to adopt this position when a truck or carriage
is detached to avoid breakages. G³, guard bar projecting from sliding
shaft to prevent same and bolt C getting out of place when coupled or
uncoupled, so that G³ may be brought down by the side of B¹ when

page_text: coupled, and so remain till the attendant makes a reverse motion,
whereby he can prove, even in the dark, if the coupling or uncoupling
is effected.
Figs. 4 and 5 show the modified form in which my Invention may be
applied to carriages or trucks where the ordinary hook is dispensed with
altogether (as when the same is removed from an old carriage or truck).
In these Figures it will be seen that the guide blocks D, D, and F, are
not used in the same form of arrangement as, in Figs. 1, 2, 3, the
coupling lever G being secured by having a rod to the spring of the
ordinary coupling hook in the place of the rod of the hook. The other
parts will remain similar to those in the other Figures. It is to be
noted that the socket or guides D, D, are to be continued by an opening
to be made in the end of the framing, or of the truck or carriage, to
allow the coupling lever to go through without damage when the buffer
springs are pressed up. Likewise that there should be a plate behind
the cross beam of carriage end and bolted right through the block D', D,
and caps in front to make all firm and solid.
Having now described the nature of the said Invention, and in what
manner the same is to be performed or put in practice, I hereby declare
that I claim this Invention, as the nature and character thercof is
described in the first part of this Specification by the words preceding
the Description of the Drawings, it being understood that I do not
limit myself to the use of the precise details and arrangements shown
by the accompanying Drawings and herein referred to, nor do I claim
such details except as constituent parts of my said Invention.
In witness whereof, I, the said James Broadley, have hereunto set
my hand and seal, this Fourth day of May, in the year of our
Lord One thousand cight hundred and seventy-one.
