PROVISIONAL SPECIFICATION.
Improved Appliance for Locking the Doors of Railway and other
Carriages.
CHARLES JOHN MOLLOY, Sawyer, Beakstown Saw Mill, Thurles, Co. Tipperary,
Ireland, do hereby declare the nature of this invention to be as follows:-
In each van working with a train, or carriage, conveying passengers on railways,
or tramways; I have a motor which is applied by the guard, or guards; individually
or collectively, this motor may be a lever or a wheel, connected to a shaft, at the
end of this shaft, I have a bevel wheel, which actuates another bevel wheel, which
is attached to a shaft running lengthways with the carriages; a shaft is fitted
to each carriage and is connected together by interchangeable clasps which
are fitted with universal joints and keys or lock pins, the shafts run in bearings
which allow for extension and contraction of length, caused by the pull or draw
on the carriages in starting, stopping, or going round curves on these shafts 1
have drums; to which chains are attached, which actuate the locks; locking the
doors, these locks are fitted into the wall of the carriage, and work independent
of existing carriage door locks; to the locks I attach another chain to which is
fitted a pull piece, or knob; so that a guard, or man in charge may be able to
unlock one door only if necessary; these appliances are fitted to each side of the
carriages or train so that one side may be kept locked when the train is stopped at
a platform.

Improved Appliance for Locking the Doors of Railway and other
Carriages.
CHARLES JOHN MOLLOY, Sawyer, Beakstown Mill, Thurles, Co. Tipperary,
Ireland, 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 :-
In each van working with a train or carriage conveying passengers on railways,
or tramways, I have a motor which is applied by the guard, or guards, or engine-
driver, or fireman, individually or collectively. This motor may be a lever or a
wheel connected to a shaft; at the end of this shaft I have a bevel wheel, which
actuates another bevel wheel, which is attached to a shaft running lengthways with
the carriages or vehicles. A shaft is fitted to each carriage or vehicle, and is con-
nected together by interchangeable clasps which are fitted with universal joints
and keys or lock-pins. The shafts run in bearings which allow for extension and
contraction of length, caused by the pull or draw on the carriages or vehicles in
starting, stopping, or going round curves. On these shafts I have drums to which
chains are attached, which actuate the locks locking the doors; these locks are
fitted into the wall of the carriages or vehicles, and work independent of existing
carriage door locks. To the locks I attach another chain to which is fitted a pull
piece or knob, so that aguard or man in charge may be able to unlock one door
only if necessary. These appliances are fitted to each side of the carriages or vehicles,
so that one side may be kept locked when the train is stopped at the platform.
On the engine or tender propelling the train, I may have a cylinder on each side,

page_text: the pistons of which are connected to shafts or bevel wheels, same as those in vans;
the cylinders are connected to the boiler by pipes, and pipes for the exhaust are
inserted into the cylinders; the feed pipe and exhaust pipe are connected by two-
way cocks which are actuated by a lever working a cam motion, so that when the
steam is being admitted to the cylinders the cock on exhaust pipe is closed, and
vice versa.

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 :-
The method or system herein described of securing the doors of carriages or
vehicles and simultaneously releasing them from the engine, van or vans, and the
method of securing the shafts working the locks.
