I, ILLIUS AUGUSTUS TIMMIS, of 2, Great George Street, Westminster, S.W.,
Civil Engineer, do hereby declare the nature of this invention to be as follows:-
The objects of my invention are to provide an efficient and economical means
of working railway points by means of electro-motors.
With these objects in view I fit an electro motor at or near the points to be
operated, connected thereto by means of gearing of any suitable kind which is
capable of converting a comparatively quick movement into a comparatively
slow one, such as worm gearing. The first movement of the motor draws out the
bolt locking the points, the points are then moved over and, on completion of
their travel, the bolt locks them again automatically. I may draw the bolt out
first by means of an electro magnet or having drawn out the bolt, hold it there
by means of an electro magnet. I repeat and detect all these movements in the
signal cabin or place where the points are controlled from so that no signal which
controls the movement of traffic over these points can show line clear until the
points are in the proper position and properly locked. This I may effect, in
addition to or instead of, the usual method (by means of detectors) by causing the
circuit passing to the signals to pass through contacts completed by the points
in the proper position, or, and, by the bolt when home. The locking bolt may be
so arranged that when the points are moved over the bolt is released and shoots in.
I fit suitable levers or switches properly interlocked in the cabin for controlling
the electric current passing to the points to operate them so that all signals in
conjunction with these points must be at " danger" before the lever controlling
the points can be operated. This interlocking may either be done mechanically
or electrically or by a suitable combination of both. The electro motor is
operated in one direction by the current passing in one direction and in the
opposite direction by the current passing in the opposite direction.
I may arrange the apparatus working the points so that when the points have
been operated and locked, i.e., the bolt is home, the current is reversed ready to
operate the points in the opposite direction. The circuit is completed when the
lever is operated in the signal cabin.
I may arrange the contacts in the cabin so that it is necessary to move the lever
over in one direction for one movement or the other for the opposite movement
of the points as the case may be.
I may arrange for the lever to he moved by hand or automatically from the
operating position to a neutral.
It is evident that the electric current (i.e., current) may be made or broken at
the points and, or, by the levers in the cabin. And the interlocking done by
electric and also by mechanical means as herein before described.

page_text: I, ILLIUS AUGUSTUS TIMMIS, of 2, Great George Street, Westminster, S.W.,
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:-
The objects of my invention are to provide an efficient and economical means
of working railway points by means of electro-motors.
With these objects in view I fit an electro-motor at or near the points to be

I may arrange the apparatus working the points so that when the points have
been operated and locked, i.e., the bolt is home, the current is reversed ready to
operate the points in the opposite direction. The circuit is completed when the
lever is operated in the signal cabin.
may arrange the contacts in the cabin so that it is necessary to move the lever
over in one direction for one movement or the other for the opposite movement
of the points as the case may be.
may arrange for the lever to be moved by hand or automatically from the
operating position to a neutral.
It is evident that the electric current (i.e., current) may be made or broken at
the points and, or, by the levers in the cabin. And the interlocking done by
electric and also by mechanical means as herein before described.
My invention will be the better understood by reference to the accompanying
drawings.
Fig. 1 represents an electro-motor A. of a suitable (preferably slow-moving) type,
a screw B is attached to or forms part of the shaft of the armature (or moving
portion) and operates a sleeve C in the usual way. C is prevented from turning
round by means of a wing D, shown in elevation in Fig. 2, sliding between two
guides E, E. Two studs or projections F, F, on the upper side of sleeve C engage
with one arm G, of crank, the other arm H, operates the points by means of
rod J. The movement of J, may be increased or decreased by means of the
moveable sleeve K, which is secured by lock nuts.

page_text: Arm G is normally locked by weighted lever L (see also Fig. 2) turning round
pin M.
A double inclined plane N projects from the under side of sleeve C.
The first movement of the sleeve causes N, to engage with roller O, and push it
outwards., Roller O, being mounted on a stud attached to lever L, causes lever L,
to rise and the projection or lock P, to drop down out of the way of arm G, thus
freeing it. The projection F, of sleeve C, then comes in contact with arm G,
operating the points by means of the gearing hereinbefore described. On the com-
pletion of the movement lock P again rises and secures arm G thus locking the
points.
Detectors (see Fig. 1) Q and R (see Fig. 2) prevent the levers operating
signals which control trains passing over the points from being moved until the
points are properly home and locked, that is to say no signal can be operated until
the points which it protects are in their proper position.
Fig. 3, represents diagrammatically the 4 positions of the lever operating the
points. The normal forward position is S (and corresponds to the position of
points as shown), the operating forward position is T, operating back position U,
normal back position V. The lever controls the electric current passing to the
electro-motor so that it is caused to move forwards or backwards and so operate
the points in one direction or the other as required.
Fig. 4 shows an arrangement whereby I operate the points by an electro
motor A as herein-before described, but lock them separately. I operate this
lock W by means of an electro magnet X (or I may use another electro-motor).
As shown the magnet is connected to a locking bar Y (of the usual type) which
is in its turn connected to the locking bolt W. Thus, if a vehicle be on the bar,
the bolt cannot be withdrawn until the vehicle has passed clear of the points.
The bolt W may or may not be operated by the same lever that operates the
points. A slot Z is provided so that in case bolt W should stick, it may be pulled
out by successive jerks of the electro magnet X by working the lever to and fro.
A light spring A normally keeps the armature of electro magnet X at its full
distance.
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. The use of electro-motors for operating and locking railway points, substan-
tially as described and for the purposes set forth.
2. The use of electro-motors for operating railway points substantially as
described and for the purposes set forth.
3. The combination of electro-motors for operating and locking railway points
with all or part of the apparatus hereinbefore described, substantially as described
and for the purposes set forth.
4. The combination of electro-motors for operating railway points with all or part
of the apparatus herein before described, substantially as described and for the
purposes set forth.
