page_text: LETTERS PATENT to George Wilson and William Kitching Hydes, both
..of Sheffield, in the County. of York, for the Invention of "AN IM.

CARRIAGES,"
"
PROVISIONAL SPECIFICATION left by the said George Wilson and
William Kitching Hydes at the Office of the Commissioners of Patents,
with their l'etition, on the 3rd November 1865.
We, GEORGE WILSON and WILLIAM KITCHING HYDES, both of Sheffield, in
the County of York, do hereby declare the nature of the said Invention for
"AN IMPROVED ARRANGEMENT OF BUFFING AND DRAWING APPARATUS FOR RAILWAY
CARRIAGES," to be as follows:-
This Invention of an improved arrangement of buffing and drawing
apparatus for railway carriages relates to a combined buffing and drawing.
action or apparatus applicable to railway carriages. The apparatus consists
mainly of one central bar, the ends of which project out at one or both ends
of a railway vehicle. This central bar is provided with wrought-iron or steel-

page_text: washers, which are fixed to the draw bar, and between which two or more
springs (as may be desired) are placed, and act both as buffer and draw
springs, which may be steel conical or volute springs, or india-rubber springs,
or they may be made of any other suitable elastic material. Wrought-iron
ferrules or nuts are screwed or pinned on to the draw bar between the
washers, and the whole arrangement is enclosed within a cast-iron case,
which may be made in two halves and beld in place by the tie rods between
the frames, or otherwise bolted or fastened, as may be convenient. These tie
rods may be made to pass entirely through the frame of the waggon or
carriage, so as to brace all the parts well together. The buffer heads are
secured to the projecting ends of the central draw and buffer rod, and links
and pins for coupling the carriages together are also adapted to the end of the
central bar, which works in a cast-iron socket that acts as the draw bar
guide. It will now be understood that when the central bar is used as a buffer,
and is thrust in upon the carriage or waggon frame, that the collar on the bar
will act, in the first place, upon the first washer, and force down the spring
upon the second washer abutting upon the cast-iron collar which is cast inside
the buffer case; in the second place, the central bar acts upon the next
washer by means of the nut, by pressing down the second spring upon the
washer behind, which abuts upon the next collar, which is cast inside the
buffer case. When on the contrary the central bar is used as a draw bar,
exactly the reverse action to that above described will take place, that is to
say, the last washer will compress the last spring, and the action will be
transferred from back to front, instead of from front to back, as when the
front buffer is acting.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Wilson and William Kitching Hydes in the Great
Seal Patent Office on the 3rd May 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GEORGE
WILSON and WILLIAM KITCHING HYDES, both of Sheffield, in the County of
York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of November, in the year of our
Lord One thousand eight hundred and sixty-five, in the twenty-ninth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said George Wilson and William Kitching Hydes, Her special

page_text: licence that we, the said George Wilson and William Kitching Hydes, our
executors, administrators, and assigns, or such others as we, the said George
Wilson and William Kitching Hydes, 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 "AN IMPROVED ARRANGEMENT OF BUFFING AND DRAWING APPARATUS
FOR RAILWAY CARRIAGES," upon the condition (amongst others) that we, the
said George Wilson and William Kitching Hydes, our executors or admi-
nistrators, by an instrument in writing under our, 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 we, the said George Wilson and William Kitching
Hydes, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement, reference being had to the Drawing
hereunto annexed, and to the letters and figures marked thereon (that is to
say):-
This Invention of "An Improved Arrangement of Buffing and Drawing
Apparatus for Railway Carriages" relates to a combined buffing and drawing
action or apparatus applicable to railway carriages.
In the accompanying Drawing Fig. 1 is a side elevation of the apparatus ;
Fig. 2 is a longitudinal vertical section of the same. The apparatus consists
mainly of one central bar, the ends of which project out at oue or both ends
of a railway vehicle. This central bar is provided with wrought-iron or steel
washers B, B1, B2, B3, which are fixed to the draw bar A, and between which
two or more springs, C, C¹, (as may be desired) are placed, and act both as
buffer and draw springs; these springs may be made in the form of conical
or volute springs, or they may be made of any other suitable elastic material,
such as india-rubber. Wrought-iron ferules or nuts D are screwed or pinned
on to the draw bar A, between the washers B' and B2, and the whole arrange-
ment is enclosed within a cast-iron case F, which may be made in two halves
and held in place by the tie rods G between the frames, or otherwise bolted
or fastened, as may be required. These tie rods G may be made to pass
entirely through the frame of the waggon or carriage, so as to brace all the

page_text: parts well together, as shewn in Fig. 2. The buffer heads K are secured to
the projecting ends of the central draw and buffer rod A, and links and pins
for coupling the carriages together are also adapted to the end of the central
bar A, which works in a cast-iron socket L that acts as the draw bar guide.
It will now be understood that when the central bar A is used as a buffer, and
is thrust in upon the carriage or waggon frame, that the collar A' on the bar
will act in the first place upon the first washer B, and will force down the
spring Cupon the second washer B' abutting upon the cast iron collar F¹, which
is cast inside the buffer case F. In the second place the central bar A acts
upon the next washer B2 by means of the nut D, by pressing down the
second spring C¹ upon the washer B' behind, which abuts upon the next
collar F2, which is cast inside the buffer case. When on the contrary the
central bar A is used as a draw bar, exactly the reverse action to that above
described will take place (that is to say) the last washer B³ will be drawn
forward by the nut E and compress the spring, and the action will be trans-
ferred from back to front, instead of from front to back, as when the front
buffer is acting.
Having now described our Invention of "An Improved Arrangement of
Buffing and Drawing' Apparatus for Railway Carriages, "and having explained
the manner of carrying the same into effect, we claim as the Invention
by Letters Patent as aforesaid, the arrangement and construc-
tion of parts herein set forth for producing a combined buffing and drawing
apparatus for railway carriages.
In witness whereof, we, the said George Wilson and William Kitching
Hydes, have hereunto set their hands and seals, the Second day
of May, in the year of our Lord One thousand eight hundred and
sixty-six.
GEORGE WILSON.
