Abstract
There is no Consid.erable modif’ication ,to the trad
i’tional fishplate joint, which consists of two fishplates,
short or long, strengthened to varying degrees by lower or
upper ribs, and held in place by bolts through ’the web of
’the rail.
Di:ffer~nt shapes of fishplates to constiarrt joints are
(29,.31)
as follow: (see fig. 1,.1)
I. Fl~t Fishplates.
2. Curved fishplates.
3~ Angle fishplates.
4. Deep- tngle fishplates~
In desiging fishplate sections, care musf be ’taken to
see that when’the rail head becomesworn ,to the perBisble
maximumextent, a worn wheel flange section will not fall
on the b.al).d of the inside fishplates.
A pair of ,the fishplates plates should have as nearJy as possible the same strrengbh and s’tiffness as ’the rails,
’they join, in order ’that ’the f:’_shplates :c.ny pr ov+d=+-hp;,...
:full share of continuity and uniformi’ty of the rail supp-
ort, bub this ideeJ. is very far from realisation in pr acb-
,-
ice, because the height of ’the fishplate section is
, ,
fixed by the height of ’the rail - web, and therefore ’the
only way tio increase ”he momentof inertia and sectrt.on
mod.ulusof ’the fishpl l:;esplates is ,to increase their width
