Improvements in Railway Carriage and other Doors.
I, FRANCIS BARTON, Jor., of Stocks Cottage, Chatburn, in the County of
Lancaster, Miller, do hereby declare the nature of this invention to be as
follows:-
Its objects are to obviate or minimise the possibility of persons having their
fingers, habiliments, umbrellas, and other articles caught, crushed or trapped,
when railway carriage and other vehicle doors are being shut, and to reduce the
noise of slamming.
In order to effectually accomplish these objects, I provide or construct the door-
jam or upright of the frame, and the edge or side of the door (either the hinged or
unhinged side, or both), with a receding piece or pieces, mounted or fixed in such a
manner on or to a spring or springs, (either coil, blade, or rubber,) or the like, as
to give way in the event of the door being closed, and a person's fingers, dress,
umbrella, &c., caught between it and the jam or frame.
The receding piece or pieces may consist of wood, flexible, or other suitable
material, and may be hinged on one side and have a spring or its equivalent between
them and the frame, in order that they may be pressed out, and held against the
corresponding part of the frame or door, as the case may be.
These receding pieces may be in sections, and extend the whole length or height
of the frame or door, or only part of it, in the latter case, rigid or solid stop pieces
are provided at the top and bottom or at intervals between.
The face or outer-side of the receding pieces may be covered, either partially or
completely, with flexible tubing,--of rubber or canvas, having high resiliency, flat
end, or bermetically sealed and containing air and other elastic fluid.

COMPLETE SPECIFICATION.
Improvements in Railway Carriage and other Doors.
I, FRANCIS BARTON, Jnr. of Stock's Cottage, Chatburn, in the County of
Lancaster, Miller, 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 the accompanying drawings:-
Fig. 1. is an elevation of the side of a railway carriage door (from the inside of
the carriage), the hinged edge of the latter being shown when open.
Fig. 2. is a side view of same.
Fig. 3. is a vertical sectional elevation of Fig. 1. on the dotted line, A-B,
looking in the direction of the arrow C, Figs. 2 and 4.

page_text: '
Fig. 4 is a sectional view on the dotted line D-E looking in the direction of the
arrow F, Figs. 1 & 2, with the carriage door shut, and the "receding-piece,"
hereinafter mentioned,-in its normal position; this view also shows the action of
the receding-piece (in dotted lines) when a finger or anything else is entrapped
between the door and door-jamb, all constructed and arranged in accordance with
my invention, the objects of which are, to obviate or minimise the possibility of
persons having their fingers, habiliments, umbrellas, or other articles caught,
crushed, or trapped when railway carriage and other vehicle doors are being shut,
and to reduce the noise of slamming.
In order to effectually accomplish these objects, I provide or construct the door-
jamb, or upright of the frame (1) and the edge or side of the door (2), (either the
hinged or unhinged side, or both) with a receding piece (3) mounted or fixed in the
following manner, so as to give way in the event of the door being closed, and a
persons fingers, dress, or umbrella, caught between it, and the jamb or frame.
"
The receding piece or pieces (3) may consist of wood, flexible, or other suitable
material, and may be hinged on one side as shown at (4) Figs. 2 and 4 and have a
spring (5) between them and the frame (1) so as to be pressed out and held against
the corresponding part of the door.
It will be obvious that the receding pieces may be attached to the door, as well
as to the frame.
These receding pieces may be in sections, and extend the whole length or height
of the frame or door, or only part of it; in the latter case, rigid or solid
stop-pieces (6) are provided at the top and bottom or at intervals between, if
necessary.
Instead of employing blade-springs in the manner illustrated at (5) Figs. 1, 2 & 3
the arrangement indicated by (7) Figs. 1, 2, & 3 may be used; (1) being the door-
frame or jamb; (7) the flexible spring, the ends of which work loosely in, and are
supported by the plates (8) the receding-piece (3) being held in position by a plate
at (9) (shown in dotted lines Figs. 1, 2, & 3) through which the blade-spring (7)
passes, or it may be securely attached to the spring by pins or screws, (9).
It will be seen that the receding pieces can be arranged to form the whole width
of the frame or edge of the door, or only part thereof.
'
The receding pieces are allowed to project (when the door is open) slightly
beyond the position they assume when the door is closed, so that they will press
against the edge of the latter (or the frame) when shut, and prevent or minimise
draught.
'
Coil springs (10) Figs. 1, 2, 3, & 4 may be substituted for the blade-springs (5)
shown in Figs. 1, 2, & 3.
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 :-
1st. The construction of railway carriage, and other doors substantially as, and
for the purpose herein before specified and illustrated by the accompanying
drawings...
2nd. In railway carriage and other doors, the method of construction substantially
as and for the purpose herein before specified and described, & illustrated, in the
drawings attached hereto by Figs. 1, 2 & 3.
3rd. In railway carriage and other doors, the method of construction, substantially
as, and for the purpose herein before specified and described, aud illustrated in the
.Dated this 5th day of April 1897.
