of the other part do hereby declare the nature of our invention for SECURING
RAILWAY RAILS TO CHAIRS AND CONNECTING RAILWAY RAILS WITH PIN PLATE
FOR FISHING RAILS, to be as follows:-
The box for connecting rails is divided into two parts as shown by figures 1
and 3 of Drawing No 2. The inner part has a wrought iron or steel plate with
two wrought iron or steel pins welded into it, as shown by F. G. H. I. K. fig 1 and
holes S, S, fig 2 one on either side to take the bolts marked Q Fig 1 and QQ fig 2
which fasten the plate to the rails. The outer part B. C. D E is a cast iron box,
and this plan may be adopted for securing rails to chairs. The pins of the plate
marked K in fig 1 and K K in fig 2 fit into the holes in the web of rails and chair
each hole being equidistant from the joint and the plate is secured to the rails by
the bolts marked QQ placed on the outer sides, The holes in the rails are made
from 1 to 3% of an inch greater in diameter than the pins and bolts to allow play
for contraction and expansion. The cast iron chair L. M. N. O used for the con-
nection is from 7 to 7'/, inches wide, After the box is placed in position and the
wrought iron split wedged Key (The split end slightly opened) marked A in
figures 1. 3 & 4 is driven 'home' the bolts with nuts complete are fixed to rails
and plate as shown by QQ Fig 2 making the whole perfectly secure without any
possible chance of a sliding motion (beyond that allowed for contraction and
expansion) as is the case with the fish plate connection now in use.

England Gentleman of the one part and FREDERICK WILLIAM STEVENS Associate.
Member of the Institution of Civil Engineers late Executive Engineer of the Public
Works Department Bombay India, on special duty Great Indian Peninsular Railway
of the other part do hereby declare the nature of our invention for IMPROVEMENTS
IN JOINT CHAIRS AND APPLIANCES FOR FISHING RAILS, and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement (reference being made to the drawing accompanying our
Provisional Specification):-
The box for connecting rails is divided into two parts as shown by Figures 1
and 3 of Drawing No 2 The inner part has a wrought iron or steel plate with
two wrought iron or steel pins welded into it as shown by F. G. H. I. K. Fig 1 and
holes S. S. Fig 2, one on either side to take the bolts marked Q Fig 1 and QQ
Fig 2 which fasten the plate to the rails, The outer part B C D E is a cast iron
box and a wrought iron split wedged Key, this plan may be adopted for securing
rails to chairs, The pins of the plate marked K in Fig 1 and K K in Fig 2 fit into
the holes in the web of rails and chair each hole being equidistant from the joint
and the plate is secured to the rails by the bolts marked Q Q placed on the outer
sides The holes in rails are made from 1 to 3 of an inch greater in diameter
than the pins and bolts to allow for contraction & expansion, The cast iron chair L.
M. N. O. used for the connection is from 7 to 71/2 inches wide. After the box is
placed in position and the wrought iron split wedged Key (the split end slightly
open) marked A in figures 1. 3, & 4 is driven 'home' the bolts with nuts complete
are fixed to rails and plate as shown by Q Q Fig 2 making the whole perfectly
secure without any possible chance of a sliding motion (beyond that allowed for
contraction & expansion) as is the case with the fish plate connection now in use.
The advantages of the invention are perfect safety, simplicity strength com-
bined with elasticity, durability, cheapness both with regard to first outlay and
maintenance, and its adaptability to the chairs & rails now in use on broad or
narrow gauge railways.
Having now particularly described and ascertained the nature of my said
invention & in what manner the same is to be performed I declare that what
I claim is
The method of securing rail points substantialley as here before described.
