I CHARLES CHALLENGER 13 Sommerville Road Bishopston Bristol Tramways!
Manager, do hereby declare the nature of this invention to be as follows:-
My invention has for its object the providing (for the greater convenience and
safety of persons using the outside or roof seats of tramway cars and other vehicles)
of ready means of communication with, the conductor or driver of said cars and:
other vehicles.
This I effect by means of apparatus arranged as follows:-On a tramway car

or other material I connect by means of levers, and rods, and cranks, and iron
piping, to a brass or iron combined socket and plate which latter is fitted with a
bell-push and spring, and this combined socket and plate is fixed on the roof of the
car. within easy reach of the passengers, preferably at each end, near, the top of
the steps or stairs. Any one of the passengers on the outside or roof desiring the
conductor or driver to stop the car strikes the bell-push, when the bell or gong
or other material affixed below sounds, and this signal is understood by the driver
and conductor and the car is stopped to enable the person or persons to descend
from the roof of the car or other vehicle..

Manager 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 :-
My invention has for its object the providing (for the greater convenience and

of ready means of communication with conductor or driver of said cars and other
vehicles.
This effect by means of apparatus arranged as follows. On a tramway car for
instance I affix to the facial board or other part of the car an ordinary tramway
car signal-bell, or one larger or smaller than ordinary to give a different tone, or a
gong, or any material capable of giving a sound when struck. This bell, or gong;
or other material I connect by means of levers, and rods and cranks and metal
piping to a brass or iron combined socket and plate which latter is fitted with a
bell-push and spring, and this combined socket and plate is fixed on the roof of the
car within easy reach of the passengers, preferably at each end of the car, near
the top of the steps or stairs. Any one of the passengers on the outside or roo

In order that my invention may be clearly understood and carried into practice
I have appended hereunto one sheet of drawings upon which I have fully
illustrated the application of my said improvements in signal-bell apparatus to an
ordinary tramway car and from which the application of same to other vehicles
wiH be readily understood.
Figure 1 shews the end elevation of an ordinary tramway car with signal-bell
apparatus fixed in position with the vertical rod Facting direct upon the bell
lever K..
Figure 2 shews the vertical rod F made to act upon the bell lever K by means
of a second lever H connected with the vertical rod F as is necessary in some cases
where through the varied construction of the car it is not convenient to fix the
vertical rod F. to act direct upon the bell lever K as shewn in Figure 1.
Figure 3 shews the face of the combined socket and plate A with the bell-push E
in the centre, with instructions on same.
Figure 4 shews the elevation of the combined socket and plate A with the
bell-push E in position for striking.
In carrying my invention into practice I fix the combined socket and plate A
which is provided on the inside at the lower end with a screw thread, to metal
piping or tube B which is also provided on the outside at its upper end with a
corresponding screw thread. The metal piping or tube B is secured in position at
its upper end by means of a clip C attached by means of rivets or screws to the
guard rail, and where it passes through the floor of the roof at the lower end it
is secured by means of a metal plate D screwed on to the metal piping or tube
and this metal plate D is secured to the floor of the roof by means of ordinary
screws.
The bell-push E is made to fit easily in the aperture of the combined socket
and plate. The bell-push E is attached by means of a screw thread to the upper
end of vertical rod F and the vertical rod F passes down through the inside of the
metal piping or tube B and the lower end of vertical rod I is provided with a
female joint by which it is connected to one end of the lever H, and the lever H is
connected at the other end to the signal-bell lever K, as in Figure 1.
Lever H, Figure 2, is made to work on a combined female joint and plate L,
the plate being secured by means of screws to the canopy of the car.
The bell-push E, which is about one and half inches in length or depth protrudes,
when in its normal position, about three parts of an inch above the level of the
face of the combined socket and plate A. On being pushed down by a passenger
for the purpose of ringing the bell N the bell-push E is made to return to its
normal position by means of a spiral spring which is shewn by dotted lines M,
Figure 4, which spring is placed inside the socket A, Figure 4.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what 1
claim is
1. The arrangement and combination of parts whereby signal-bell apparatus for
tramway cars and other vehicles is made to operate substantially as hereinbefore
described and as shewn upon the annexed drawings.
2. In signal-bell apparatus for tramway cars and other vehicles the combined
socket and plate with bell-push. and spiral spring substantially as described by
reference to Figures 3 and 4, letters A, E, M.
