EDWARD MARTIN 57 Lambs Conduit Street W.C. London Mechanic 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 traffic indicator is made to fix on the back of an omnibus car or other vehicle
it is intended as a preventative against accidents in giving warning to traffic following
that the vehicle is about to slacken speed or stop it is connected with the foot brake
and worked automatically with the foot brake by the driver or if fixed to any motive
power such as gas or electricity by the man under whose control the vehicle may be
if drawn by horses it gives the driver full use of both his hands to control his horses
which is very requisite in case of congestion of traffic instead of giving the signal
with his whip or putting up his hand. The working of the indicator is as follows
directly the driver applies his foot to the brake A in Fig. 4 it acis on the indicator
opening the doors as in Fig. 2. Doors open showing the word stop in large letters
which are filled in with block tin or silver plated spangles which vibrate with the
motion of the vehicle directly the driver releases the brake A Fig. 4 the doors close as
in Fig. 1 also will be a fine medium for advertisements both novel & attractive.
The indicator is constructed in the following manner a piece of wood 16 in. x 16 bylin.
thick forms the foundation of the indicator on the front of this is fixed a pair of
doors 13 with rising hinges on (front of) each door is fixed an arm or elbow C that

manner the same is to be performed I declare that what I claim is

2nd. Connexion with foot hand or any other kind of brake and under the control of
