Improvements in the Methods of Fishing and Supporting the Joints
of Tramway and other Rails.
ALFRED DICKINSON of Tramway Depot Darlaston in the County of Stafford
Tramway Manager and 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 :-
The Invention has for its object the improvement in the method of fishing and
supporting the joints of tramway and other rails and of preventing the springing and
other defects that exist with the previous methods of jointing.
In order that my invention may be properly understood and carried into practical
effect without difficulty I have appended hereunto one sheet of drawings upon which
five figures of various parts of the chair upon a rail are given.
Figure 1 is a plan shewing the casting with the rails fixed in position and secured
to the sole of the casting D by means of the bolts E which may be fixed after the
chair is in position by being passed through the holes F and held in position by the
fillet plate G which also forms an even bearing with the flange of the rail for
the washers H which together with the nuts J hold the flange of the rail in position
the top portion of the casting has a chequered surface forming the paving block K.
Figure 2 is a section through the casting and rail on the line C. C. Figure 1
shewing the web of the rail secured to the back of the casting L which is provided
with fillet M by means of the bolts N and the ordinary fish plate O.
Figure 3 is an end elevation of the casting and section through the rail shewing
an end view of the stiffening wings P and the chequered surface or paving block K.
Figure 4 is an elevation on the line A. A Figure 1 giving a view of the
back L the stiffening wings P the chequered surface or paving block K and also
the heads of the bolts E & N.
Figure 5 is an elevation on the line B. B Figure 1 shewing the ordinary
fish plate O. the fillet plate G the bolts E and N the holes F and the washers H.
The combination of the figures tending to shew the method in its completed form
the rails being secured and held in position as hereinbefore described.
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 that what I
claim is
--
1st. The improvements in the method of fishing and jointing tramway and other
rails by which means an even bearing is obtained for the flange and head of the rails
and greater steadiness is obtained substantially as and for the purpose set forth and
shewn upon the accompanying drawing.
2nd. A casting of iron steel or other approved metal forming a combined fish chair
and sole plate in conjunction with the ordinary fish plate and bolts substantially as
herein set forth and shewn upon the drawing.
3rd. The method of inserting the bolts after the casting is in position by means of
the holes F and securing the same in position by means of the fillet plate G
substantially as herein set forth and shewn upon the drawing.
Dated this Twenty-third day of April 1890.
