PROVISIONAL SPECIFICATION.
An Improved Reversible Rail, Fish Plate, and Chair for use on
Railways.
JOHN EDWARDS, Carpenter & Joiner, 30, Coolinge Road, Folkestone, Kent, do
hereby declare the nature of this invention to be as follows:-
Is to provide & make a rail in such a way, so as to allow of its being used in
conjunction with rails in use at present by a slight alteration in the fish plate the
said rail to be reversible & to be supported without resting on its bottom edge.
1st. I make half the projection of the lange beyond the web to form a square
shoulder the other part is made to form a suitable shape with the edge of rail.
2nd. 1, also make the top edge of the inside or fixed jaw of chair to fit under
the top shoulder the other part of jaw is made to fit close up to the web and
is cut away to clear the bottom shoulder, so that the rail is supported on the top
edge of the said fixed or inside jaw of chair.
3rd. I also make an outside loose or lever jaw the top edge being in the form
of a rabbit, one part of the said rabbit fitting under the top shoulder of the out-
side of rail the other part fitting close against the edge of rail, the outside bottom
edge abbutting on the base of the key jaw in other respects it is the same as the
fixed or inside jaw of chair, it also as a wedge shaped slot in the centre of the
width on the bottom side which fits on a similar shaped wedge piece or stop
abbutting on the key jaw and fixed on the bottom of chair the object being to
prevent the said loose jaw from moving sideways while the wood key is being
driven in.
4th. 1, also make them without the key or key jaw, by leaving part of the base of
the said key jaw to form an abutment for the loose or lever jaw, in some cases the
jaws of the chair could be cast solid to fit the section of rail.
5th. 1, also bevel off the bottom of chair from the centre outwards either way
under the rail to prevent any ballast resting there and so injuring the said bottom
edge of rail.
6th. 1, also make a fish plate, one half the length is made to fit the section of
rails in use at present, the other half is made to fit the improved section of rail, thus
allowing them to be used in conjunction.
7th. I also make an improved fish plate to fit the improved section of rail the
whole of its length the said fish plate only requiring one bolt on either side of joint
in rail in place of two as at present.
8th. The object of the loose jaw is that ou pressure being brought to bear on
the top edge rail the said loose jaw acting as a lever to grip the web tight between
the jaws, thus relieving the shoulders of part of the strain at the same time, taking
the pressure off the wood key, thus preventing it from working loose.
9th. By my invention the rail is supported on the top edges of jaws of
chair under the top shoulder not by resting on the bottom edge as at present, thus
preventing the said bottom edge from being cut by the friction on the chair.
Dated this Second day of August 1890.

An Improved Reversible Rail, Fish Plate, and Chair for use on
Railways.
JOHN EDWARDS, Carpenter & Joiner, 30, Coolinge Road, Folkestone, Kent,
do hereby declare the nature of this invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement :-
Is to provide and make a rail in such a way so as to allow of its being used
in conjunction with rails in use at present, by a slight alteration of the fish
plate; the said rail to be reversible, and to be supported without resting on its
bottom edge.
1. I make half the projection of the flange beyond the web to form a square
shoulder the other part is made to form a suitable shape with the edge of rail
shown on drawing at B. Fig. 1.
2. I also make the top edge of the inside or fixed jaw of chair, to fit under the top
shoulder, the other part is made to fit close up to the web and is cut away to clear
the bottom shoulder so that the rail is supported on the top edge of the said fixed or
inside jaw of chair as at B. Fig. 1.
3. I also make an outside loose or lever jaw the top edge being in the form of a
rabbit as shown at C. Fig. 1. one part of the said rabbit fitting under the top
shoulder, the other part fitting close to the edge of rail; the outside bottom edge
abutting on the base of the key jaw.
It also has a wedge shaped slot, which fits on a similar shaped wedge piece or
stop, fixed on the bottom of chair and shown at D. Fig. 1.
4. I also make them without the key or key jaw by leaving part of base
of the said key jaw to form an abutment for the loose or lever jaw as at E.
Fig. 1.
5. I also bevel off the bottom of chair from the centre outwards either ways under
the rail as at F. Fig. 1.
6. I also make an improved fishplate, one half the length is made to fit the
section of rails in use at present and shown at G. Fig. 2. the other half to fit
the improved section of rail as at H. Fig. 2.
7. I also make another improved fish plate to fit the improved section of rail the
whole of its length as at H. Fig. 2.
8. By my invention, the rail is supported on the top edges of jaws of chair, and
not on the bottom edge as at present, thus preventing the said bottom edge from
being cut by the friction on the chair.
The object of the loose jaw is that on pressure being brought to bear on the
top edge of rail, the said loose jaw acting as a lever, to grip the web tight
between the jaws, thus relieving the shoulders of part of the strain, at the
same time preventing any pressure on the wood key, to prevent its working
loose.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare what 'I claim,
is as follows:-
1. The use of reversible rail A. Fig. 1.
2. Loose jaw 1." Fig. 1 also slot and stop shown at D. Fig. 1. with abutment,
as shown at E. Fig. 1. and the beveling off as shown at F. Fig. 1.
