Improvements in or relating to Station Indicators or Combined
Station Indicators and Signalling Mechanism.
I, THOMAS ELLIOTT, of 21 Pelham Street, in the Borough of Nottingham, Furrier
and Mantle Merchant, do hereby declare the nature of this invention to be as
follows:--
This invention relates to improved apparatus for indicating in each compart-
ment of a train the several stations, junctions, or the like on the line as the train
approaches each in turn. The apparatus may be also used in conjunction with
apparatus for signalling to the driver or guard or both.
In carrying out my invention each carriage is provided with an approximately
vertical slide, a lever, or other convenient mechanism, the lower end of which is
carried below the carriage and engages with and is raised, by raised platforms or
striking parts placed at the required points on the line.
At a convenient part of the carriage is a transverse shaft mounted in suitable
bearings, this shaft is provided with a ratchet wheel which is operated by a pawl
connected to the slide or lever before-mentioned, and the said shaft is thus inter-
mittently advanced or rotated the required distance by each raised platform
or striking part of the line.
The transverse shaft is connected by an intermediate shaft and bevel toothed
wheels, to a longitudinal shaft carried preferably over the top of the carriage.
In a convenient position in each compartment, is a rotating cylinder, on the
periphery of which are printed the names of the stations in their proper order.
The axis of each cylinder is connected preferably by a short shaft and bevel
toothed wheels, to the longitudinal shaft, so that the whole are rotated through the
required space simultaneously.
The axis of the cylinders are connected to their operating mechanism by suit-
ably formed clutches, in order that they may be readily removed and interchanged
as required, for cylinders on which the names of the station correspond with the
particular route or line the carriage may be for the time being running on.
The cylinders may be also enclosed in a suitable box or casing provided with an
opening of sufficient size to expose the name of one or more stations at once as
desired.
In order that the same cylinder may be used for a carriage travelling in either
direction between two points, the transverse shaft is provided with two bevel
wheels, either of which may be moved into engagement with the wheel on the end
of the intermediate shaft, and the direction in which the cylinders rotate is thus
reversed.
The arrangement described may be fitted to the engine and guards van, in

page_text: addition it may be in either or both cases connected in foggy or other unfavour-
able weather to the brake mechanism so as to automatically apply the brake, or be
connected to other suitable indicator mechanism adapted to attract the attention
of the driver or guard or both.
The above described mechanism is preferably arranged so that it may be thrown
out or into action by either the driver or guard or by both as required.

Improvements in or relating to Station Indicators or Combined
Station Indicators and Signalling Mechanism.
I THOMAS ELLIOTT, of 21, Pelham Street, in the City of Nottingham, Furrier,
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:—
This invention relates to improved apparatus for indicating in each compart
ment of a train, the several stations, junctions, or the like, as the train approaches"
each in turn. The apparatus may also be used in conjunction with apparatus for
signalling to the driver or guard.
The invention will be best understood by reference to the accompanying
drawings in which
Fig. 1. is an end elevation, and
Fig. 2. a side elevation (partly in section) of a railway carriage showing my
invention applied thereto.
Fig. 3. is a front elevation, and
Fig. 4. a vertical cross section of the indicator mechanism.
Fig. 5. is a vertical front elevation, and
:
Fig. 6. an end elevation of the indicator operating racket wheel and pawl, and
the reversing arrangement.
Like letters indicate like parts throughout the drawings.
In carrying out this invention each carriage A (see Figs. 1. and 2.) is provided
with a bracket B which may be secured to the underframing of the carriage, and
on the lower end of the said bracket is pivotted a curved shoe or lever C. This
shoe or lever C engages with and is raised by inclined planes or striking parts I)
placed at the required parts on the permanent way, when the carriage travels past
the said points, whether the carriage is moving in the direction indicated or in
the reverse direction.
The shoe or lever C is connected by a link E to one end of an intermediate
lever F which is pivotted on the bracket B as shown. The other end of the lever F
is connected by a link G to a bell-crank lever H (see Figs. 1. 2. 5. and 6.) which
is mounted loosely on a shaft I carried in bearings formed on a plate J secured to
the back of the carriage.
The shaft I is provided with a rachet wheel K which is advanced by a pawl L
on the bell-crank lever H, and two level toothed wheels M M which slide longi-
tudinally on the shaft I but are connected thereto by a feather-key in the one
engaging with a corresponding keyway in the other.
.
Either of the wheels. M M may be moved into engagement (by means herein-
after described) with a bevel toothed wheel N secured on the lower end of a

page_text: •
vertical shaft N¹ carried in bearings №2 N2 secured to the plate J and carriage. A
respectively.
This shaft N¹ is connected by bevel toothed wheels O, O, (see Figs. 1. and 2.)
to a longitudinal shaft P carried along the top of the carriage, the said shaft being
carried in bearings P¹ secured to the roof of the carriage.
In each compartment of the carriage is a casing Q (see Figs.
2. 3. and 4.) pro-
vided with a glass front or opening Q and above the casing Q is a removable cas-
ing R. Mounted in bearings secured to the latter are two rollers S S₁ on which
is a flexible band S2 on which the names of the stations are printed, this flexible
band is wound off one roller on to the other and in its passage passes over an idle
roller S3 placed opposite to the glass front or opening Q¹ of the casing Q, where
the names of the stations are each in turn exhibited.
17
The two rollers S S₁ are connected to each other by toothed wheels TT and the
former to a toothed wheel T2 secured on a' transverse shaft U, the latter is con-
nected by a clutch U¹ to a shaft U2 which is connected by a bevel tooth' wheel U³
to the longitudinal shaft .P.
}
The shaft U is carried in bearings secured to the casing R, and the shaft U³
to bearings secured to the top of the carriage.
The casing R together with the mechanism therein may thus be removed bodily
and be replaced by a casing and mechanism on the band of which is a different list
of stations.
The flexible band S2 may be made to travel in either direction as required by
moving either of the wheels M and M into engagement with the wheel N, this
may be effected by means of a lever W (see Figs. 1. and 2.) pivotted on the end of
the carriage, the upper end of which lever is provided with a fork which engages
with an annular recess in the boss of the two wheels M M¹.
The lower end of the lever W is connected to a sliding bar X by means of which
it may be operated from either side of the carriage.
As the carriage passes over each point where an incline D is fixed, the shoe or
lever C is raised and the pawl L moved through an angular space carrying the
wheel K with it which will advance the mechanism sufficiently to bring the next
station on the band S2 into view.
The extent of the movement of the shoe or lever is limited by stops Y Y acting
on the lever F in order to prevent it from overrunning when the carriage is
travelling at a great speed.
The rachet wheel and pawl, and the reversing mechanism may be enclosed in
a casing Z as shown.
The arrangement described may be fitted to the engine and guards van, and
in addition it may be connected in foggy weather, to the brake mechanism so
as to automatically apply the brake, or be connected to audible indicator
mechanism adapted to attract the attention of the driver and guard.
The above described audible indicator mechanism is preferably arranged so that
it may be thrown out or into action by either the driver or guard or both as
required.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that I am
aware that it has been previously proposed to place upon railway carriages station
indicators actuated by inclines fixed upon the permanent way and that I make
no general claim thereto but what I claim is
(1.) In station indicator mechanism the combination with an inclined plane such
as D on the permanent way of a curved lever or shoe such as C pivotted on a
carriage or a bracket secured thereto substantially as described.
(2.) In station indicator mechanism the combination with an inclined plane
such as D on the permanent way of a curved lever or shoe such as C pivotted on
a carriage or a bracket secured thereto a rachet wheel K paw L and reversing

page_text: gear such as that provided by the toothed wheels M M¹ and N substantially as
described.
(3.) In station indicator mechanism the combination with a flexible band S2
on which the names of the stations are printed of rollers S and S¹ for carrying the
said band one or both being connected to the operating mechanism and an inter-
mediate roller S₁ placed opposite an opening in the casing and over which the said
band is carried as it passes from one roller S to the other S or vice versa sub-
stantially as described.
(4.) In station indicator mechanism the combination with a fixed casing Q
placed in the interior of the carriage and provided with an opening Q¹ of a detach-
able exterior casing R to which the bearings of the rollers S $1 and $3 and shaft U
are attached and a detachable clutch U for connecting the shaft U to the oper-
ating mechanism in order that said casing R and indicator mechanism may be
removed and interchanged substantially as described.
(5.) The combination and arrangement of parts constituting the complete
station indicator mechanism substantially as described and illustrated in the
accompanying drawings.
nated this 8th day of October 1897.
