I, LINCOLN GORDON, District Traffic Superintendent, Oudh and Rohilkhand
Railway, Lucknow, at present residing at Lucknow, in the Province of Oudh, in
British India, do hereby declare the nature of the said invention for securing railway
wagons in lie-by or other sidings to be as follows:--
This invention relates to a railway appliance termed a scotch block worked by
means of a "points" lever in connection with a trap rail and applied to rails for
the purpose of securing vehicles in lie-by and other sidings without the aid of safety
chains or other contrivances in use at present and this block being connected by rod
with the lever that works the points, it is off the rail when the trap is closed and the
points are set to permit wagons entering or leaving the siding, and when the points
are against the siding it is on the rail and the trap open.
In the drawings annexed hereto and which are to be read as part of
this specification the same letters or numerals indicate the same parts in each
figure
Figs. 1 and 3 show the block "off" the rail with the points set to release or admit
vehicles.
"
Figs. 2 and 4 show the block " on the rail with the points closed and the trap
open to admit of derailment when necessary.

Referring to the drawings-This scotch block as will be seen, consists of three
parts A the upper part of the block proper which rests on the rail B, A¹ the lower
part which is bolted to rail web by bolts a, b, c, and a hinge A which connects the
top and bottom parts. From the top part h of hinge A³ projects a leg C the toe of
which is connected to the end of points lever rod D which is actuated by points
lever E and moves block A off or on to the rail, and simultaneously moves points F
to or from trap rail G and opens or closes the forward points H by means of rod J.
The top part h of hinge is attached to block A by bolts m and the lower part f to
lower part A¹ of block, by bolts a, b, c, passing through web of rail. This scotch
block may be made of any suitable material.
The scotch block is attached to the rail at a point opposite to or in front of the
trap rail, so that vehicles set in motion by a high wind would come in contact with
and if moving at a moderate speed be stopped by the block without derailing them
but should the vehicles be moving at such a high speed as to demolish the block
on coming in contact with it then they would be thrown off the line at the trap.

rail by the tension of lever rod D a reversal of the motion throwing the block on to
the rail.
Improvements in and connected with Railway Scotch Blocks.
I, LINCOLN GORDON, District Traffic Superintendent, Oudh and Rohilkhand Rail-
way, Lucknow, at present residing at Lucknow, in the Province of Oudh, in British
India, do hereby declare the nature of my invention for improvements in and
connected with railway scotch blocks and in what manner the same is to be
performed, to be particularly described in and by the following statement :-
This invention relates to a railway appliance termed a scotch block worked by
means of a "points" lever in connection with a trap rail and applied to rails for the
purpose of securing vehicles in lie-by and other sidings without the aid of safety
chains or other contrivances in use at present, and the blocks being connected by rod
with the lever that works the points it is off the rail when the trap is closed and the
points are set to permit wagons entering or leaving the siding and when the points
are against the siding it is on the rail and the trap open.
In the drawings left with Provisional Specification and which are to be read as part
of this specification the same letters or numerals indicate the same parts in each
figure.
Figs. 1 and 3 show the block "off" the rail with the points set to release or admit
vehicles.
Figs. 2 and 4 show the block " on "the rail with the points closed and the trap
open to admit of derailment when necessary.
Fig. 5 is a plan of the block on the rail.
Fig. 6 is a back elevation of same.
Fig. 7 is a vertical cross section of same on line Q X.
Fig. 8 is a perspective view of back and end of block on rail.
Referring to the drawings this scotch block as will be seen consists of three parts,
A the upper part of the block proper which rests on the rail B, A¹, the lower part
which is bolted to rail web by bolts a, b, c and a hinge A' which connects the top and
bottom parts. From the top part h of hinge A² projects a leg C the toe of which is
connected to the end of points lever rod D which is actuated by points lever E and
moves block A off or on to the rail and simultaneously moves points F to or from trap
rail G and opens or closes the forward points H by means of rod J. The top part h of
hinge is attached to block A by bolts m and the lower part f to the lower part A¹ of
block, by bolts a, b, c passing through web of rail. This scotch block may be made of
any suitable material.
The scotch block is attached to the rail at a point opposite to or in front of the trap
rail, so that vehicles set in motion by a high wind would come in contact with and if
moving at moderate speed be stopped by the block without derailing them: but
should the vehicles be moving at such a high speed as to demolish the block on
coming in contact with it then they would be thrown off the line at the trap.
In Fig. 7 the dotted lines show the position of the block when thrown back off the
rail by the tension of lever rod D a reversal of the motion throwing the block on to the
rail.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and the mode or manner in which it is to be performed I do declare that what
I claim is
1. The combination of a scotch block, a trap rail and a pair of points, all worked by
one lever substantially as described and illustrated.
Dated this Twentieth day of April 1898.
