Improvements in Apparatus for Controlling the Points of Railway
Lines.
I, PAUL SIEFELDT, of Odessa, Russia, Manufacturer, 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:-
The object of the present invention is an apparatus which renders it unnecessary
to employ a number of special men for working railway points and enables this
operation to be effected by the engine driver himself letting down a roller con-
nected to the apparatus to left or right as required by aid of a lever, according
to whether the train is to be turned to the left or the right.
In the accompanying drawings:-
Figure 1 is a perspective view of the apparatus with a car, which directs the
locomotive.
Figure 2 is a plan view and
Figure 3 a detail.
The apparatus comprises the following:
The locomotive, or if this is placed at the rear of the train, the front car
of the train, is provided with two rollers c c placed at each end of a curved
axle bone at each side of the track and situated in front of or between the
wheels. These rollers are arranged in such a manner that if one of them, for
instance, c, is raised by the engine driver, the second e falls and vice versa.
Not far from the switch d, outside the two rails e e¹ and resting independently
on the plates g, g, are two switch points f. f which are so connected at one end
to a bar passed through the rails ce, that when one of the points, for
instance f, is pressed against a rail, the other f¹ is moved away from its rail e¹.
In this manner the roller c when it presses between the point f and the corre-
sponding rail e whilst the train is moving shifts one of the points f from its
rail e and consequently presses the other f against its rail e¹.
The moving of the points fi f¹ to and from the rails is transmitted to the
switch d by means of a lever i one end of which is connected to the bar h and
the other to a T-piece which oscillates round a pin o right or left according to
the movement of the points f fl.
The link kis connected to a similar T-piece by means of two pairs of
rods with couplings, preferably screw-couplings m; the piece k¹ likewise
oscillates right and left on its axis o¹ and by means of this is again connected
with a lever i which is in connection with the middle connecting bar h¹ on the
end of the switch.
In this manner the movement of the point f, f¹ is effected by one of the
rollers c c being forced in between them and the rails e e¹ and is transmitted to
the switch by means of the device described. The switch is thus caused to
move to the left or to the right, so that the train can be driven either to the
left or right.
In the apparatus just described the curved axle 6 with the rollers c c² and also
the device for lowering a roller by means of the lever a¹ can be modified, and

page_text: the distance between the points f f and the switch can be greater or less
according to requirements without departing from the principle of the invention.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:―
1. Apparatus for enabling the engine driver to adjust the points from the
train, characterized by the engine or the front car a of the train having in front
of or between the wheels, two rollers situated one on each side of the track on
the ends of a curved axle & preferably pivoted, which rollers are so arranged that
when the engine driver raises one of them (for instance c) by means of a lever a',
the second roller is lowered and vice versa.
2. In an apparatus as characterized in Claim 1 two points f f located outside
the two rails e e¹ and coupled by means of a bar h together with a lever & which
is connected to a T-shaped piece K oscillating to right and left, said piece being
again connected to a similar piece which moves the point either to the right or
to the left by means of a lever i and a bar ¹, substantially as described.
