PROVISIONAL SPECIFICATION.
Improvements in Carriage Doors.
I, THOMAS LEES, of the King's Arms Hotel, Girvan, in the County of Ayr,
North Britain, Hotel Keeper, do hereby declare the nature of this invention to be.
as follows, that is to say :-
My said invention has for its object the prevention of accidents and personal
injury by the closing of carriage doors, and especially doors of railway carriages,
as com nonly constructed. Ordinarily a carriage door is constructed and attached
to its coor frame in a manner, when the door is opened, to present an angular gap
between the inner edge of the door and the door frame, a gap in which a passenger
may inadvertently place a hand or one or more fingers, and have it or them
severely crushed on the door being closed. Railway-carriage doors having to be
closed rapidly are generally closed with great and probably in many cases
unnecessarily excessive force, and the injury caused by them is proportionately
great.
In carrying out my invention the door is made with a rounded edge at the side
at which the door is hinged to the door frame, and the door frame is made with a
rounded cavity in which the rounded edge of the door fits and can turn; and with
this construction no dangerous gap of the kind hereinbefore referred to is formed
when opening the door. The improved door is attached to the door frame by
suitable metal hinges at the top and bottom, and also at one or more intermediate
points if considered desirable.
If it is desired to provide for the door opening to a greater extent than a quarter
of a turn, the part hereinbefore described as hinged to the door frame is not a
rigidly fixed part of the door, but is itself hinged to the door in the same manner
as it is hinged to the door frame. This modification will allow of the door when
opened being turned completely over against the side of the carriage or to any less
extent.
Instead of having the convex rounded part on the door and the concave part on
the door frame, the convex part may be on the door frame and the concave part on
the door.

COMPLETE SPECIFICATION.
Improvements in Carriage Doors.
I, THOMAS LEES, of the King's Arms Hotel, Girvan, in the County of Ayr,
North Britain, Hotel Keeper, 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, that is to say :-
My said invention has for its object the prevention of accidents and personal
injury by the closing of carriage doors, and especially doors of railway carriages,
as commonly constructed. Ordinarily a carriage door is constructed and attached
to its door frame in a manner, when the door is opened, to present an angular gap
between the inner edge of the door and the door frame, a gap in which a passenger
may inadvertently place a hand or one or more fingers, and have it or them severely
crushed on the door being closed. Railway-carriage doors having to be closed

excessive force, and the injury caused by them is proportionately great.
In carrying out my invention the door is made with a rounded edge at the side
at which the door is hinged to the door frame, and the door frame is made with a
rounded cavity in which the rounded edge of the door fits and can turn.
If it is desired to provide for the door opening to a greater extent than a quarter
of a turn, the part hereinbefore described as hinged to the door frame is not a
rigidly fixed part of the door, but is itself hinged to the door in the same manner
as it is hinged to the door frame.
. Instead of having the convex rounded part on the door and the concave part on
the door frame, the convex part may be on the door frame and the concave part on
the door.
And in order that my said invention and the manner of performing the same may
be properly understood I hereunto append a sheet of explanatory drawings to be
hereinafter referred to and showing in horizontal section three simple and convenient
modifications of my improved carriage door.
As represented in Figure, 1, on the drawings the door, D, which is shown
closed, is made with a rounded edge, E, at the side at which the door, D, is hinged
to the door frame, F, and the door frame, F, is made with a rounded cavity, C, in
which the rounded edge, E, of the door, D, fits and can turn; and with this con-
struction no dangerous gap of the kind hereinbefore referred to is formed when
opening the door, D. The improved door is attached to the door frame, F, by
suitable metal hinges, H, at the top and bottom, and also at one or more intermediate
poiuts if considered desirable.
As represented in Figure, 2, an additional piece, P, is provided which is not a
fixed part of the door, D, but is itself hinged to the door, D, in the same manner
as it is hinged to the door frame, F. This piece, P, is made with a rounded
edge, R, which fits and turns in the cavity, C, of the door frame, F, and it is also
formed with a wing, W, which has formed in it an additional cavity, A, in which
the rounded edge, E, of the door, D, fits and turns. This modification will allow
of the door, D, when opened as shown in Figure, 2, being turned completely over
against the side of the carriage or to any less extent.
As represented in Figure, 3, the parts are reversed as compared with Figure, 1,
that is the rounded edge, E, is formed on the door frame, F, instead of on the door, D,
and the cavity, C, is formed in the door, D, instead of in the door frame, F. In
this figure, the door is shown a little open.
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. Making the hinge edge of a carriage door convexly or concavely rounded to
fit a concavely or convexly rounded part of the door frame, substantially as and for
the purposes hereinbefore described.
2. Making a carriage door with a part hinged to it and to the door frame, the
hinge parts being rounded substantially in the manner and for the purposes herein-
before described.
