PROVISIONAL SPECIFICATION.
Improvements in the Method of and Means for Securing Railway
Rails in their Chairs.
I, JAMES HENRY LYNDE, of Buckland, Ashton on Mersey, in the County of
Chester, Civil Engineer, do hereby declare the nature of this invention, which has
been communicated to me from abroad by Francis Gascoigne Lynile, of Ahmedabad,
India, Civil Engineer, to be as follows:
This invention relates to improvements in the method of and means for securing
railway rails in their chairs.
The improved meaus consists of a key formed of a specially bent strip or plate
of steel of suitable thickness and preferably somewhat wider than the chair. The
upper corners of the plate are preferably turned outwards and the lower corners of
the plate are notched by removing two small pieces. The plate is then bent into
such a shape that it can be placed in the space between the chair and the rail with
the upper bent corners resting against the jaw of the chair under the upper curved
or horn" portion and when in this position the prongs of a hooked or bent claw
bar are placed under the corner notches in the lower edge of the key with the
booked portion of the bar extending back over the top of the rail; a crow bar is
then passed through the loop of the hooked bar and by pressing the point of the
crow bar say against the chair for a fulcrum and pulling it back the hooked bar is
also drawn back and thereby forces the lower edge of the key over the bottom
head of the rail and the spring in the key causes it to press firmly on the upper
and lower parts of the web of the rail as well as under the horned portion of the
jaw of the chair thus securing the rail firmly into the chair, the bent upper corners
preventing the key from moving end wise out of its true position.
The key may be of such a shape that lugs or ears may be required on its sides
in the place of the turned over corners of the upper edge.

COMPLETE SPECIFICATION.
Improvements in the Method of and Means for Securing Railway
Rails in their Chairs.
I, JAMES HENRY LYNDE, of Buckland, Ashton on Mersey, in the County of
Chester, Civil Engineer, do hereby declare the nature of this invention which has
been communicated to me from abroad by Francis Gascoigne Lynde, of Ahmedabad,
India, Civil Engineer, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention relates to improvements in the method of and means for securing
railway rails in their chairs.
The improved means consists of a key formed of a specially bent strip or plate of
steel of suitable thickness and somewhat wider than the chair with its upper corners
turned outwards.

page_text: And in order that this invention may be fully understood and readily carried
into effect I will describe the accompanying sheet of drawings reference being had
to the figures and letters marked thereon.
Fig. 1 is an end view, Fig. 2 a plan of Fig. 1, and Fig. 3 a side view of a
railway rail fitted into a chair and secured by the improved key. Fig. 4 is a
detached view of the key shown in Figs. 1, 2 and 3 and Figs. 5 and 6 are end views
of modified forms of keys.
In the drawings, a represents part of a railway rail, a railway chair of ordinary
form into which the rail a is secured by one of the improved keys c which is shown
clearly in Fig. 4. The key c is formed say of a rectangular plate of steel, some-
what wider than the horn of the chair, bent to a suitable shape so that it can be
placed in the space between the horn of the chair and the rail as shown clearly in
dotted lines, Fig. 1, the upper corners of the key being bent outward.
To raise the key and secure the rail in the chair any suitable lever or bar inay
be employed such as a bar with two right angled projections one at the end to fit
in the loop of the key and the other near this end so that when in position with the
end projection placed in the loop and the other projection laid upon the horn of
the chair as a fulcrum by applying pressure to the other end of the lever the key
will be forced into the position shown in full lines Fig. 1, with its lower edge upon
the bottom head of the rail; the spring in the metal and the particular shape of
the key cause it to press firmly against the upper part of the web of the rail and
also against the upper part of the horn while the lower edge of the key bears upon
and is supported by the bottom head of the rail thus firmly securing the rail while
the bent upper corners c¹ of the key prevent it from moving end wise out of its true
position.
Having now particularly described and ascertained the nature of this said
invention and in what manner the same is to be performed I declare that what
I claim is
1. The combination with a rail, of a key formed of a plate of steel bent into
such shape that it can be placed between the jaw of the chair and the rail and
then be forced vertically and locked in position to secure the rail in the chair
substantially as and for the purposes described and as illustrated in the
accompanying drawing.
2. The several constructions of keys substantially as and for the purposes
described and as illustrated in the accompanying drawing.
