IMPROVEMENTS IN THE PERMANENT WAY OF RAILWAYS
Year: 1857

page_text: LETTERS PATENT to Henry Whatley Tyler, of 12, Norfolk Crescent,
Hyde Park, in the County of Middlesex, Captain, Royal Engineers, for
the Invention of "IMPROVEMENTS IN THE PERMANENT WAY OF RAILWAYS."
PROVISIONAL SPECIFICATION left by the said Henry Whatley Tyler
at the Office of the Commissioners of Patents, with his Petition, on the
28th February 1857.
I, HENRY WHATLEY TYLER, of 12, Norfolk Crescent, Hyde Park, in the
County of Middlesex, Captain, Royal Engineers, do hereby declare the nature
of the Invention for "IMPROVEMENTS IN THE PERMANENT WAY OF RAILWAYS," to
be as follows:-
This Invention has for its object a method of securing bolts and nuts by
which the ends of railway rails are bolted to fishing plates when fishing plates
are employed, and also bolts and nuts which are employed for fixing railway
rails to their chairs or supports, so as to prevent such bolts and nuts from
turning and so becoming loose. For this purpose, for connecting the ends of.
railway rails to fishing plates when fishing plates are used, I employ bolts and
nuts in which the heads of the bolts or the nuts are made smaller on the
insides or parts which come against the fishing plates than on the outsides, and
in conjunction with bolts and nuts so made I employ a plate having notches:
cut in it to fit the smaller parts of the heads of the bolts or of the nuts,. and,

page_text: when the bolts and nuts are screwed up I drive this plate down over such
smaller parts of the heads of 'the bolts or of the nuts, and the bolts and nuts
are thus secured from turning until the plate is removed. Or, when using
bolts and nuts of the ordinary description, I secure them from turning by
means of a plate having holes in it to correspond with the heads of the bolts
and the nuts, and whon the bolts are screwed up I drive this plato over the
heads of the bolts or over the nuts, and there secure it by chisel cutting such
heads or such nuts, or otherwise. Sometime I secure in this manner both
the heads of the bolts and the nuts, and sometime only one of these, according
to circumstances. When bolts and nuts are used to fix railway rails to their
chairs or supports, I secure the heads of such bolts and such nuts by methods
similar to those already described.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry Whatley Tyler in the Great Seal Patent Office on
the 28th August 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
WHATLEY TYLER, of 12, Norfolk Crescent, Hyde Park, in the County of
Middlesex, Captain, Royal Engineers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of February, in the year of our
Lord One thousand eight hundred and fifty-seven, in the twentieth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Henry Whatley Tyler, Her special licence that I, tho said Henry
Whatley Tyler, my executors, administrators, and assigns, or such others as
I, the said Henry Whatley Tyler, 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 PERMANENT WAY OF RAILWAYS," upon the condition
(amongst others) that I, tho said Henry Whatley Tyler, 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.

page_text: NOW KNOW YE, that I, the said Henry Whatley Tyler, 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, that is to say:―
This Invention has for its object a method of securing bolts and nuts by
which the ends of railway rails aro bolted to fishing plates when fishing plates
are employed, and also bolts and nuts which are employed for fixing railway
rails to their chairs or supports, so as to prevent such bolts and nuts from
turning and so becoming loose. For this purpose, for connecting the ends of
railway rails to fishing plates when fishing plates are used, I employ bolts and
nuts in which the heads of the bolts or the nuts are made smaller on the
insides or parts which come against the fishing plates than on the outsides,
and in conjunction with bolts and nuts so made I employ a plate having
notches cut in it to fit the smaller parts of the heads of the bolts or of the
nuts, and wlien the bolts and nuts aro screwed up I drive this plate down
over such smaller parts of the heads of the bolts or of the nuts, and the bolts
and nuts are thus secured from turning until the plate is removed. Or, when
using bolts and nuts of the ordinary description, I secure them from turning
by means of a plate having holes in it to correspond with the heads of the
bolts and the nuts, and when the bolts are screwed up I drive this plate over
the heads of the bolts or over the nuts, and there secure it by chisel cutting
such heads or such nuts, or otherwise. Sometimes I secure in this manner
both the heads of the bolts and the nuts, and sometimes only one of thesc,
according to circumstances. When bolts and nuts are used to fix railway
rails to their chairs or supports, I secure the heads of such bolts and such nuts
by methods similar to those already described.
And in order that my said Invention may bo most fully understood and
readily carried into effect, I will proceed to describe the Drawings hereunto
annexed.
Figure 1 is a transverse section, and Figure 2 is a side view, of an ordinary
fished joint with my system of locking the nuts of the screw bolts applied to
it. a is the end of one of the rails, and b, c, are the two fishing plates; d, d,
are bolts passing through the rail and the fishing plates. The heads of these
bolts rest in a groove rolled in the fishing plate 6, and are so prevented from
turning; e, e, are nuts, which screw on to the other ends of the bolts d, d.
A perspective view of one of the nuts e is shewn at Figure 3; it will be seen
that it is made square for one half of its thickness, and octagonal for the other
half. is the locking plate, which is pushed down between the fishing plate
and the square part of the nut. A separate view of this plate is shown at

page_text: way
Figure 4, and another form of it is shown at Figure 5. In this it will
be seen that the nuts may be securely locked in any one of eight positions.
Figure 6 is a transverse section of a fished joint, in which the system is
applied to lock both the head of the bolt and the nut.
Figure 7 is a transverse section of a fished joint, where the system is
applied only to lock the head of the bolt, the other end of which screws into
a hole tapped in one of the fishing plates.
Figure 8 is a transverse section of a fished joint, in which the screw nuts
are locked by means of a plate with holes forced over the nuts, and secured
by. afterwards chisel cutting the sides of the nuts. a is the end of one of the
rails; and b and c are the two fishing plates, as before; d are the bolts; and
6, the nuts of the ordinary description, either square, hexagonal, or other
form; ff, is the locking plate, two different forms of which are shewn at
Figures 9 and 10.
Figure 11 is a side view, and Figure 12 a section, of a one-jaw railway
chair to which the rail is secured by a bolt, which is locked at one end by its
head falling into a small indentation stamped in the side of the rail, and at
the other end by a locking plate forced down between the larger part of the
nut and chair.
In witness whereof, I, the said Henry Whatley Tyler, have hereunto
set my hand and seal, this Sixth day of August, in the year of our
Lord One thousand eight hundred and fifty-seven.
HENRY WHATLEY TYLER. (L.S.)
