PROVISIONAL SPECIFICATION.
Improvements in or relating to Railway Chairs.
We, GEORGE EDWIN HITCHENOR and CHARLES WILLIAM ST. LAWRENCE
both of Manchester Road, Wilmslow, Clerks do hereby declare the nature of our
said invention to be as follows:-
These improvements relate to railway chairs and have for their object to more
effectually support and join the ends of the rails of railways than heretofore,
dispense with the fish plates and reduce the unpleasant jolting which is experienced
in passing over such joint to a minimum.
The ends of the rails to be connected together meet in the centre of our improved
chair and recessed into the chair underneath the ends of the rails is a cushion of
india rubber or other soft clastic material. The opening or channel in the chair
for the key or wedge instead of being open throughout is tapered off to a dead end
and after the key or wedge has been driven into position a peg or stud is placed
behind the thicker end of the key thus serving to effectually prevent its coming out
of position.
An effective joint is thus obtained without the use of fish plates or bolts and nuts
and further by reason of the elastic cushion the jumping of the train over the joint
is avoided.
This form of connection is specially adapted to spliced rails or rails tapered off
with their edges facing each other.
Dated this 30th day of June 1892.

COMPLETE SPECIFICATION.
Improvements in or relating to Railway Chairs.
We, GEORGE EDWIN HITCHEXOR, and CHARLES WILLIAM ST. LAWRENCE,
both of Manchester Road, Wilmslow, Clerks, do hereby declare the nature of our
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 improvements relate to railway chairs and have for their object to more
effectually support and join the ends of the rails of railways than heretofore,
dispense with the fish plates and reduce the unpleasant jolting which is experienced
in passing over such joint to a minimum.
As illustrated on the accompanying drawing
Fig. 1 represents an elevation of our improved railway chair showing the rail in
section, Fig. 2 a plan view and Fig. 3 a perspective view of the same..
In carrying out our invention the ends A. A. of the rails to be connected
together meet in the centre of our improved chair 13, and recessed into the chair
underneath the ends A. A. of the rails is a cushion C of india-rubber or other soft
elastic material (as shewn more clearly in transverse section Fig. 4).
The opening or channel in the chair B for the key or wedge E instead of being
open throughout is tapered off to a "dead-end" (seen more clearly in Fig. 4)
and after the key or wedge E has been driven into position a peg or stud G is
placed behind the thicker end of the key thus serving to effectually prevent its
coming out of position.
As a train passes over the chair it tends to drive the wedge towards the dead-
end, hence as the wedge becomes worn away it is prevented coming out of the
chair by said end whilst it is effectually stopped from working out of the chair in

page_text: the opposite direction by the stud G. Moreover an effective joint is obtained and
without the use of fish plates or bolts and nuts and by reason of the elastic cushion,
the jumping of the train over the joint is reduced to a minimum as aforesaid.
This form of connection is specially adapted to spliced rails, or rails tapered off
with their edges facing each other (as shewn in perspective view Fig. 3).
Having thus particularly described and ascertained' the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1st. A railway chair provided with an elastic pad or cushion on which the ends
of the two adjoining rails may meet and rest substantially as and for the purposes
herein before described and illustrated on the accompanying drawing.
2nd. A railway chair constructed with a "dead end"F and provided with a
locking peg, stud or bolt G substantially as and for the purposes hereinbefore
described and illustrated on the accompanying drawing.
Dated this 25th day of February 1893.
