PROVISIONAL SPECIFICATION.
An Improved Device for Preventing the Displacement of Railway
Sleepers.
I, LOUIS GEORGES BAUCHAL, of 34 Rue du Champ des Oiseaux, Rouen, in the
Republic of France, Engineer, do hereby declare the nature of this invention to
be as follows:-
My invention relates to a device for preventing the displacement of railway
sleepers.
In order that railway sleepers may not shift under the action of the rolling
stock a point of support is taken upon the stratum of ballast situated below the
sleepers, which stratum is loaded by the upper stratum of the ballast, by the fixed
material of the way, and by the rolling stock.
For obtaining a support I fix to the extremity of the whole or part of cross
sleepers a rectangular spade or pallet which has nearly the height of the lower
stratum of ballast and juts out laterally from the said sleepers.
The fixing of the spade upon wooden cross sleepers may be effected either
directly or by squares of iron placed on the side or below, or by pieces
of wood.
With longitudinal sleepers and metallic cross sleepers the mode of fixing the
spade necessarily varies with the kind of sleeper employed.
The spade may be made of wood or of metal, either solid or pierced with holes
for the passage of water, or open-worked in any suitable manner. For augmenting
the strength it may rise above the lower level of the ballast.
In curves the spades may be all or nearly all attached on the side of the small
radius. In straight parts of the railway they may be placed alternately on one
and the other side in the case of a single line, and in greater number on the outer
side in the case of a double line.
The spades may be fixed to the middle of the cross sleepers instead of the
extremity; 1 may if necessary place several spades upon a single cross sleeper.

An Improved Device for Preventing the Displacement of Railway
Sleepers.
I, LOUIS GEORGES BAUCHAL, of 34 Rue du Champ des Oiseaux, Rouen, in the
Republic of France, 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 a device for preventing the displacement of railway
sleepers, and is illustrated in the accompanying sheet of drawings in which
Figure 1 shews the device attached to a transverse sleeper.

page_text: Figures 2 and 3 are respectively a front elevation and side view to an enlarged
scale of the said device.
Figure 3 represents in plan the square or bracket employed when using hard
wood, and
Figure 4 in plan the said bracket or square employed for soft wood.
In order that railway sleepers may not shift under the action of the rolling
stock a support is taken upon the stratum of ballast situated below the sleepers,
which stratum is loaded by the upper stratum of the ballast, by the fixed material
of the way, and by the rolling stock.
For obtaining a support I fix to the extremity of the whole or part of cross
sleepers a a rectangular spade or pallet b which has nearly the height of the lower
stratum of ballast and juts out laterally from the said sleepers.
The fixing of the spade upon wooden cross sleepers may be effected either
directly or by squares c of iron placed on the side or below, or by pieces
of wood.
With longitudinal sleepers and metallic cross sleepers the mode of fixing the
space necessarily varies with the kind of sleeper employed.
The spade may be made of wood or of metal, either solid or pierced with holes
for the passage of water, or open-worked in any suitable manner. For augmenting
the strength it may rise above the lower level of the ballast.
On curves the spades may be all or nearly all attached on the side of the smallest
radius. In straight parts of the railway they may be placed alternately on one
and the other side in the case of a single line, and in greater number on the outer
side in the case of a double line.
The spades may be fixed to the middle of the cross sleepers instead of the
extremity ; I may if necessary place several spades upon a single cross sleeper.
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 :-
The employment of the hereinbefore mentioned spade for preventing the
displacement of railway sleepers, substantially as above described.
