I GEORGE ROOKE Norman Road Englefield Green, near Staines Carpenter, 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 indicator is composed of two (2) pointers moved simultaneously by a system
of cogs and chain as shewn on accompanying drawing. These pointers work over
two dials marked with a series of directions most likely to be required by the
occupant of the cab or carriage so that when the pointer inside the cab is placed by
the occupant on a certain direction the pointer on the face of the dial, in front of
the driver & on the roof of the cab or carriage shews the same direction.
The electric bell, to call driver's attention to the dial is placed immediately
behind the dial box on roof & the button is just below the dial inside the vehicle.
The inside dial & pointer is placed in the right band recess in the front of the cab
or carriage leaving ample room for the casements to work properly.
The casings are of oak (or other hard wood) well polished and completely water-
proof, screwed up with brass cup screws.
The dials are enamelled iron, the outside one being protected by a glazed door.
The connecting chain is of brass wire.

The two (2) cogs marked "B" on accompanying drawing are cast in gun metal
and the 4 rollers marked " are of box wood, running on steel axes.
These guide
the chain and being wood, prevent any unnecessary clanking or other noise.
The pointers are of brass, the one inside the vehicle having a neatly turned ivory
knob working on a pivot.
The driver by leaning over the top of the cab or other vehicle as the case may
be can easily replace the pointers by a small brass thumb screw, thus leaving them
both in an upright position for the use of the next passenger.
The side pieces marked "C" on drawing are merely wooden ledges, to fix block
above, containing the runners; & the slip marked "d" is an upright backing which
takes the pin for the lower cog to revolve upon.

page_text: The cogs have brass plates screwed to backing to allow them to run freely.
Immediately over the dial inside vehicle is an enamelled iron direction plate
bearing the following direction :—
"NOTICE.
Press button, and place pointer on direction wished to be transmitted to the
driver.
The Figures 1, 2 & 3 indicate the 1st, 2nd or 3rd turnings to the right or left
respectively."
The word "push" is plainly marked on button: this simplifying the direction.
The battery for electric bell will be the "A B W dry cells " & placed in a small
casing on floor of cab, out of the way of the occupante.
The electric wires will follow the direction of the chain.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:-
1. That the invention affords a communication between driver & occupant of cab
or carriage, in a manner & by use of an apparatus which to the extent of my
knowledge is not in use at present.
Dated this 19th day of December 1894.
