page_text: LETTERS PATENT to John Farmerley Dickson, of No. 6, Russel Street,

PROVISIONAL SPECIFICATION left by the said John Farmerley Dickson at
the Office of the Commissioners of Patents, with his Petition, on the
9th November 1858.
I, JOHN FARMERLEY DICKSON, of No. 6, Russel Street, Litchurch, near
Derby, in the County of Derby, Engineer, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN THE CONSTRUCTION OF RAILWAY CHAIRS
AND OTHER DETAILS CONNECTED WITH THE PERMANENT WAY OF RAILWAYS," to be
as follows:-
This Invention consists, firstly, of an improved modification of the chair at
present in general use, by the extension of that part of the chair upon which
the rail rests, and also in constructing such chairs so as to give, if prefered,
a bearing of wood, or other elastic substance, to the bottom of the rail.
Secondly, of an improved adaptation of wrought instead of cast iron in the
formation of railway chairs, whether such chairs form part of wrought-iron
sleepers, or are used as ordinary chairs upon wood or other bearers.
Thirdly, an improvement in "fish joints," wherein the bottom of the rail..

page_text: bears upon one of the wrought-iron "fishes" resting upon the chair on either
side of the joint.
Fourthly, an improvement, by which I propose to support the rail between
blocks of wood or metal, the lower surface of such rail not resting upon the
chair or sleeper.
Fifthly, an improvement in railway keys or wedges, such being formed of
metal, so as to receive a block or packing of wood, or other elastic material,
and I also propose, in some cases, so to construct the chairs as to allow a
packing of wood or other material to be inserted, in which case keys wholly
of metal may be applied.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Farmerley Dickson in the Great Seal Patent Office,
on the 7th May 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JoпN
FARMERLEY DICKSON, of No. 6, Russel Street, Litchurch, near Derby, in the
County of Derby, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent bearing date the Ninth day of November, in the year of our Lord,
Oue thousand eight hundred and fifty-eight, in the twenty-second year of
Her reign, did, for. Herself, Her heirs and successors, give and grant unto
me, the said John Farmerley Dickson, Ier special licence that I, the said
John Farmerley Dickson, my executors, administrators, and assigns, or such
others as I, thc said John Farmérley Dickson, 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 THE CONSTRUCTION OF RAILWAY CHAIRS AND
OTHER DETAILS CONNECTED WITH THE PERMANENT WAY OF RAILWAYS," upon the
condition (amongst others) that I, the said John Farmerley Dickson, by an
instrument in writing under my hand and seal, 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
Offico within six calendar month next, and immediately after the date of the
said Letters Patent.

page_text: NOW KNOW YE, that I, the said John Farmerley Dickson, 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 (that is to say) :-
.
Firstly, this Invention consists of an improved modification of the chair at
present in general use, by the extension of that part of the chair upon which
the rail rests, and also in constructing such chairs, so as to give, if preferred,
a bearing of wood, or other elastic substance, to the bottom of the rail.
Secondly, of an improved adaptation of wrought instead of cast iron in the
formation of railway chairs, whether such chairs form part of wrought-iron
sleepers, or are used as ordinary chairs upon wood or other bearers.
Thirdly, an improvement in "fish joints," wherein the bottom of the rail
bears upon one of the wrought-iron "fishes" resting upon the chair on either
side of the joint.
Fourthly, an improvement by which I propose to support the rail between
blocks of wood or metal, the lower surface of such rail not resting upon the
chair or sleeper.
.Fifthly, an improvement in railway keys or wedges, such being formed of
metal so as to receive a block or packing of wood or other elastic material.
And I also propose in some cases so to construct the chairs as to allow a
packing of wood or other material to be inserted, in which case keys wholly of
metal may be applied.
Which improvements will be clearly understood by referring to the accom-
panying Sheet of Drawings with the letters of reference thereon.
Fig. 1 is an elevation, and Fig. 2 a plan of an improved modification of the
railway chair at present in general use, the part a upon which the rail rests
being extended so as to give greater bearing surface, which may, when
preferred, be furnished with a block of wood a', or other clastic substance.
Fig. 3 is an elevation of an improved wrought-iron chair attached to a
sule plate and sleeper, the chair is of simple and convenient form, and the
keys b may be either of wood or metal.
Fig. 4 represents an improved "fish joint," the bottom of the rail bearing
upon one of the "fishes," the chairs being constructed so as to allow the
"fish" to rest upon the chair at each side of the joint.
Fig. 5 represents an improvement by which the rail c is supported between
blocks d of wood or metal, so that the lower surface of the rail will not rest
upon the chair or sleeper.
Figs. 6 and 7 are transverse views of my improved railway keys or wedges

page_text: which are formed of metal, in connection with a block or packing of wood or
other elastic material; c represents a key wholly of metal, the chair being
constructed as at f, to allow a packing of wood. At g the key is formed of
metal, so as to receive a block or packing of wood, drawn enlarged at Fig. 7.
Having thus fully described the nature of my said Invention, and the manner
in which the same is to be performed, I desire it to be distinctly understood
that I do not confine myself to the precise details herein set forth, as such
may be varied or modified without departing from the principle thereof; but
I claim as my Invention, and which to the best of my knowledge and belief
has not been hitherto used within the realm,
Firstly, an improved railway chair by an extension of that part of the chair
upon which the rail rests, and constructed so as to give a bearing of wood or
other clastic substance to the bottom of the rail.
Secondly, an improved wrought-iron chair attached to the sole plate and
sleeper.
Thirdly, an improved fish joint in which the bottom of the rail bears upon
one of the wrought-iron fishes resting upon the chair on either side of
the joint.
Fourthly, an improved method of supporting the rail between the blocks of
wood or metal, the lower surface of the rail not resting upon the chair or
sleeper.
And, fifthly, an improvement in railway keys or wedges formed so as to
receive a block or packing of wood or other elastic material, as all such
improvements are herein described and illustrated in the accompanying Sheet
of Drawings.
In witness whereof, I, the said John Farmerley Dickson, have hereunto
set my hand and seal, this Sixth day of May, in the year of our Lord
One thousand eight hundred and fifty-nine.
JOHN FARMERLEY DICKSON. (L.S.)
Signed, sealed, and delivered by the within-
named John Farmerley Dickson, in the
presence of
JOHN COOPER.
