PROVISIONAL SPECIFICATION.
Improvements in and relating to Railway Switches.
I GEORGE WILLIAM HORNE 146 Sinclair Road Kensington W. Mining
Engineer do hereby declare the nature of this invention to be as follows :-
1 propose to use on the one side of the switch, the usual tongue or split switch
point, and on the other side a full rail with square end, as used in America, and
called a stub switch.
These are fastened in the usual way with fish-plates to the standing rails, at one
end, the other or moving ends are connected with each other by means of a lever
and rods, outside or inside the rails,-preferably by a lever pivoted between the
rails, the ends of which are joined or linked to the moving ends of the rails, and
thus the movement of one rail is communicated to the other in a reverse manner,
with the result that they work in unison, opening and closing the points, so that
when the split rail lies against the standing rail on its side, the stub rail buts against
and coincides with the outer standing rail on its side, thus opening the siding, and
when the split rail, or point is opened, the stub rail simultaneously moves inwards
and buts against and coincides with the inner or main-line rail, thus closing the
siding, and opening the main line, at the same time giving a safe, unbroken line.
I propose to work the combination by a rod attached to the stub-rail, and
connecting rods, cranks &c. in the usual way.
I also provide a locking aparatus in the shape of a bolt or wedge, which I fit to
slide between the standing rails against which the stub rail buts, in such a manner
that the bolt or wedge interlocks with the moving end of the stub-rail in either
position of the points.
In conjunction with the lock-bolt, I also have wedges or keys which simultaneously
shoot into the spaces between the stub-rail and its chairs or chocks, when in main-
line position, thus avoiding any risks of the rail spreading or moving when in use.
The locking-bolt and chair wedges are worked together by the oue movement,
this being done by the use of rods and cranks in the usual way.

COMPLETE SPECIFICATION.
Improvements in and relating to Railway Switches.
I, GEORGE WILLIAM HORNE 146 Sinclair Road Kensington W. Mining
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:-
I propose to use on the one side of the switch, the usual tongue or split switch
point and on the other side a full rail with square end as used in America and
called a stub switch. These are fastened in the usual way with fish plates to the
standing rails at one end, the other or moving ends are connected with each other
by means of a lever and rods outside or inside the rails preferably by a lever
pivoted outside the rails the ends of which are joined or linked to, the moving ends
of the rails and thus the movement of one rail is communicated to the other in a
reverse manner, with the result that they work in unison, opening and closing the
points, so that when the split rail lies against the standing rail on its side, the stub

page_text: rail buts against, the outer standing rail, on its side, thus opening the siding and
when the split rail or point is opened the stub rail simultaneously moves inwards
and buts against & coincides with the inner or main line rail, thus closing the
siding and opening the main line, at the same time giving a safe unbroken line. I
propose to work the combination by a rod attached to the stub rail and connecting
rods, cranks etc. in the usual way. I also provide a locking apparatus in the shape
of a bolt which I fit to slide between the standing rails against which the stub rail
buts, in such a manner that the bolt interlocks with the moving end of stub rail in
both positions of the points. In conjunction with the lock bolt, I also have wedges
or keys which simultaneously shoot into the spaces between the stub rail and its
chairs or chocks, when in main line position, thus avoiding any risks of the rail
spreading" or moving when in use.

The locking bolt and wedges are worked together by the one movement, this
being done by the use of rods and cranks in the usual way.
Referring to the annexed drawing Figure 1 is a plan view of my arrangement.
a & a¹ are the main line rails b is the moveable stub rail connected by the rod c
to the lever d which is pivoted at e. A 1od connects the split rail g to the lever d.
h is a handle or crank connected by the rod i to the lever dat j. k is a lever
pivoted at and carrying the wedge m which slides between the main line rail a¹ &
the shunt line n. A rod o is attached to this lever k, which passes through a

the lever by the rod s. The action is as follows. By operating the handle r the
wedges m & 9 are withdrawn to the position shown by the dotted lines 1. By now
operating the handle the stub rail b may be caused to butt on the shunt line n,
the split rail g bearing on the main line rail a. The handle is again operated and
the wedge m locks the stub rail b in the shunting position; the wedges having

been brought to the position marked 2 by the movement of the rod c, & so on.
this arrangement it will be seen that the rail is locked in the main line position by
the wedges entering between the rail b & the chairs or chocks u which are
enlarged for this purpose and in the shunt position the stub rail is supported

plate joints or connections.
Having now particularly described and ascertained the nature of my said
invention & in what manner the same is to be performed I declare that what 1
claim is.
1. In switches or points for vehicle rails, the combined construction and arrange-
ment of the various parts substancially as described and illustrated herein.
2. In switches or points for vehicle rails, the combination of a split rail and a
butt jointed movable rail known as a "stub rail" said split rail being connected to
one end of a pivoted lever, to the other end of which the stub rail is connected
said lever being operated as desired so that when the split rail is in the shunting
position the stub rail is opposite the shunt rail substantially as described.
3. In switches or points for vehicle rails, a pivoted lever carrying a tapered
wedge which slides between the main line and shunt line, a rod pivoted to said
lever and passing through a bearing upon a rod which connects the stub rail to
the lever operating same said rod passing through the bearing having tapered wedges
which enter between the stub rail and the sides of the chairs when the stubb
rail is in its locked main line position, levers operating said rails and locking
wedges, substantially as described and illustrated.
