COMPLETE SPECIFICATION.
A Safety Apparatus for Preventing Accidents in the Slamming of
Carriage Doors.
I, FÉLICIEN CORNIL of Gilly, in the Kingdom of Belgium, Manufacturer, do hereby
leclare 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 an apparatus adapted to prevent accidents in the slamming
of the doors of railway and other carriages, and its object is to prevent the door closing
on the hand of a passenger.
In the accompanying drawing which illustrates this invention;
Figure 1 is an interior view of a carriage door, provided with my apparatus.
Figure 2 is a front view of the lever.
Figure 3 a top view of the same.
Figure 4 a top view of the door, showing the action of the apparatus.
Figure 5 a front view of the ratchet wheel and catch, and
Figure 6 a plan view of the same.
Throughout the views similar parts are marked with like letters of reference.
A narrow door C made of sheet iron, is secured inside the carriage on the upright,

edges is formed as a hinge-socket g, through which passes a cable H, formed of
twisted steel wires, constituting the spring of the narrow door above mentioned.
This cable is attached at one end to the ratchet-wheel A, secured inside the seat
and at the other end to the lever B, pivoting in the piece D and to which is fixed
the narrow door C. This lever is furnished, at its free end, with a roller R, running
on a piece F (the surface of which is concave) applied to the top of the carriage
door. The roller may be made of hardened india-rubber to prevent the noise
produced by door slamming, or it may be made of metal surrounded by an
india-rubber ring.
The twisting device A is composed of a

In the action of closing the door, the lever B is repelled, drawing with it the
narrow door C, so that if a person's hand is in the doorway it is promptly pushed
out of the way of the door before the latter can reach it. To prevent the narrow
door C from striking the leg of a passenger sitting near it, the said narrow door is
cut away at its lower part as shown at k in Figure 1.
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 :-
A safety apparatus adapted to prevent passenger's hands from being crushed in
the doorway of Railway and other carriages, consisting essentially of a narrow door (

the accompanying drawing.
