I JULES CHARLES CAILLÉ of 4 Rue Guy la Brosse, Paris, France, Civil Engineer,
do hereby declare the nature of this invention to be as follows:-
My invention relates to an improvement in the permanent way of railways, and it
has for its object to prevent the jolting caused by the passage of the wheels over the
joints of the rails.
The invention consists of a fish plate of extra length extended upwards alongside
the head of the rail and slightly convexed or hogbacked so as to project up to or above
the level of the rails in the region of the joint sufficiently to form an additional bearing
for the wheels to run on, thus bridging over the joint.
In order that the invention may be readily understood, I will proceed to describe it
with reference to the accompanying drawings, wherein figure 1 represents an elevation
and figure 2 a plan of the improved rail joint. Figures 3 and 4 are cross sections
showing the invention as applied to different forms of rail.
The portion of the wheel tyre which overhangs the outside of the rail runs upon an
additional bearing fixed at the outside of the rail at the joints, this bearing b consisting
of a fish plate which is bolted to the rails a like an ordinary fish plate and projects up
alongside the head of the rail so that the wheel c will momentarily bear thereon in
passing a joint as shown in figure 4. As the wheel tyres would wear more slowly by
contact with this fish plate than by contact with the rails, this inequality of wear
would sooner or later lead to shocks were the plate to be at the same level as the
rails for its entire length, and to obviate this I make the upper surface of the fish
plate slightly hogbacked or sloping from the middle towards each end as shown in
figure 1. The fish plate is for this purpose made of considerable length and is
symmetrically disposed with regard to the joint, its summit being rather above than
below the level of the rails, whilst the ends of the plate should be as much lower than
the middle as will about equal or rather exceed the maximum amount of wear of the
tyres before being returned.

page_text: The fish plate at the inside of the joint is of the ordinary description.
In applying this fish plate to double headed rails additional space must be provided
in the adjacent chairs for its reception.
The invention may be adapted to all forms of rails whether laid on wood or metal
cross or longitudinal sleepers and applies to any kind of fish plate or counter rail
utilizing this overhanging portion of the wheel tyre to prevent shocks by the wheels
passing over the rail joints.

page_text: I, JULES CHARLES CAILLÉ of 4, Rue Guy la Brosse, Paris, France, Civil 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 an improvement in the permanent way of railways; and
it has for its object to prevent the jolting caused by the passage of the wheels over the
joints of the rails.
The Invention consists of a fish-plate of extra length and width and slightly convexed
or hog-backed so as to project upwards alongside the head of the rail to or above the
level of the rails in the region of the joint, so as to form an additional support for the
wheels to run on, thus bridging over the joint.
In order that the invention may be readily understood, I will proceed to describe it
with reference to the drawings left with my provisional specification, wherein figure 1
represents a longitudinal elevation and figure 2 a plan of the improved rail joint.
Figures 3 and 4 are cross-sections, shewing the invention as applied to different forms
of rails, drawn to a larger scale. Figure 5, accompanying this complete specification,
represents a modification.
The portion of the wheel tyre which overhangs the rail, runs upon an additional
supporting or bridge piece fixed on the outside of the rail at the joint, this support b
consisting of a fish plate which is bolted to the rails a in the ordinary manner and
which projects up alongside the head of the rail so that the wheel c will momentarily
bear thereon in passing over a joint, as shewn in figure 4.
b
As the wheel tyres would wear more slowly by contact with this fish plate b than
by contact with the rails, this inequality of wear would sooner or later lead to shocks,
were the plate 6 to be at the same level as the rails for its entire length, and to obviate
this, I make the upper surface of the fish plate 6 slightly hog-backed or sloping down-
wards from the middle towards each end, as shewn in figure 1. The fish plate is for
this purpose made of considerable length and is symmetrically disposed with regard to
the joint, its summit being rather above than below the level of the rails and its ends
as much lower than the mid-portion as will about equal or rather exceed the maximum
amount of wear of the wheel tyres before they are re-turned.
In the example shewn, the improved fish plate b is employed in combination with a
fish plate 6 of the ordinary description, at the inside of the joint, the ends of the
combined fish plate and joint bridging piece 6 being fastened by four additional
bolts.
In applying this fish-plate to double-headed rails additional space must be provided
in the adjacent chairs for its reception.
The improvement may be adapted to all forms of rails whether laid on wood or
metal cross or longitudinal sleepers, and may be applied to any kind of fish plate or

page_text: counter rail for utilizing the overhanging portion of the wheel-tyre in order to prevent
shocks when the wheels pass over the rail joints.
a
The fish plate may be made of the same length as the sections of the rail, in which
case it would be a continuous support for the wheels, the two forming together,
compound rail, as represented in cross-section in figure 5. In this case, the joints of
the rails would be opposite the middle of the fish-plate as before, but the fish plate
being continuous would not be curved or hog-backed as before described.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is ;-
The herein described means for preventing jolting at the joints of railway rails 3
which consists of a fish plate rising alongside the outside of the rail head to or above
the level thereof and presenting a solid support for the wheel opposite the rail joint,
the said fish plate either being slightly convex or forming a continuous bearing
for the overhanging portion of the tyre to travel on, as specified.
