PROVISIONAL SPECIFICATION.
Improvements in and relating to the Permanent Way of Railways.
I, JAMES SEDDON CHEESMAN of May Bank Villa, Gittens Street Oswestry in the
county of Salop, Engineer do hereby declare the nature of this invention to be as
follows:-
My invention relates to the joints of the rails of permanent ways, and has for its
object the increased rigidity of the joint, and its maintenance in a rigid condition
after it is once made.
I carry out my invention as follows:-I use the ordinary double-headed section of
rail and the usual fish plates. At each joint I use a chair constructed with one jaw,
and the rails are bolted to this jaw by four bolts, which pass through the jaw of the
chair and then through the rail and the fish plates. The two end bolts are locked by
nuts direct on to the outer fish plate in the ordinary manner. A locking plate
consisting of a flat plate with a dovetailed or other convenient shaped recess formed
in one side, is then passed over the inner pair of bolts, and is locked by nuts screwed
on the ends of the bolts. This locking plate is sufficiently long to fit between the
sides of the heads of the nuts on the outer bolts, and so prevents their turning or
becoming loose. In the dovetailed recess in the locking plate is placed another
locking piece, which fits between the sides of the heads of the nuts of the inner pair
of bolts, and also prevents their turning and becoming loose. When bolts are used
with square heads and without square shanks I form suitable projections on the chair
to engage with one, or more, sides of the heads of the bolt and so prevent their
turning.

Improvements in and relating to the Permanent Way of Railways.
I JAMES SEDDON CHEESMAN of May Bank Villa, Gittens Street, Oswestry in the
County of Salop, Engineer, 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 :-
My invention relates to the joints of the rails of permanent ways, and has for its
object the increased rigidity of the joint and its maintenance in a rigid condition
after it is once constructed.
I carry out my invention as illustrated in the accompanying drawings in which
Figs. 1 and 2. Sheet No. 1. are side elevations of my improved joint. Fig. 3.
Sheet No. 2. is a plan thereof, and Fig. 4. Sheet No. 2. is a transverse section on the
line a, y. of Fig. 3.
Throughout the several views similar parts are marked with like letters of
reference.
A
I use the rail A. of the ordinary double headed section, and also the ordinary fish
plates B. B. as at present used. At each joint I use a chair C. constructed with but
one jaw. The rails A. A. are bolted to this jaw by bolts c. c. which pass through the
jaw of the chair and through the rail and fish plates. The fish plates B. B. are also
bolted to the rails A. A. by bolts b. b. and nuts in the ordinary manner.
locking plate D. consisting of a flat plate with a dovetailed, or other convenient
shaped recess, d. formed in one face of it, is passed over the bolts c. c. and is locked
by nuts ec¹ screwed on the ends of the bolts c. c. The locking plate D. is sufficiently
long to fit between the sides of the nuts &¹¹ on the bolts . b., and so prevents their
turning or becoming loose. In the dovetailed recess d. in the locking plate D. is
fitted another locking plate E. which fits between the sides of the nuts c¹ c¹ of the
bolts c. c. and also prevents their turning or becoming loose. When bolts with square
heads are used without square. shanks, I form suitable projections on the chair to
engage with one
or more sides of the heads of the bolts c. c. to prevent their
turning.
The advantages I claim for my invention are:-
1. The joints of the rails which are the weakest parts of a permanent way, are so
strengthened by putting the chair on a sleeper exactly under the joints, and leaving
the usual fish plates on, that all springing will be entirely prevented as each of the
rails has an equal bearing on the chair.
2. All the fish bolts and nuts are locked without injuring the threads, therefore
when once screwed up they cannot possibly become slack. The chair locking the
square headed bolts, and the locking pieces securing the nuts.
3. The locking pieces can easily be removed when required to unfish the joint, and
the bolts, nuts, and fish plates-can-be taken off, without disturbing the chair from the
sleeper.

page_text: 4. Owing to the sleeper and chair being exactly under the joint, the intermediate
sleepers can be put equal distance apart, which will allow ample room for the joint
sleepers to be properly and evenly packed, which with the present system is difficult
to do, as the sleepers are to near to one another at the joint."
5. The chair can be made to suit any section, of flat bottom double, or bull head,
rail or fish joint, whether the bolts have square heads with round necks, or square
necks with round heads.
6. The chair can be made to suit ordinary chairs, whether keyed inside the rail, or
outside, and the rail may be turned out without taking the chair from the sleeper, and
having only one jaw will be about the weight of an ordinary chair and
7. The sleepers can be removed without having to take the chair from the rail.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed I declare that what I claim is :-
1. The improved joint for the permanent way of railways, constructed, and
arranged substantially as herein before set forth.
2. The combination with the rails A. A. of the single jaw chair C, the fish
plates B. B, the locking plate D, the locking plate E., the bolts bb and c c, and the
nuts ¹¹ and c¹ c¹, all arranged, and operating, as and for the purpose hereinbefore.
set forth.
3. In a fish plate joint for the permanent way of railways, the double locking
plates D, and E, constructed, arranged, and operating, as and for the purpose herein-
before set forth.
