I, ALFRED GARDNER, of Perseverance Street, Sale, in the County of Chester,
Plasterer, 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 and accompanying drawings : -
" +11
My said invention relates to railway and other carriage doors and has for its

page_text: object to provide means whereby the trapping of fingers on the sudden closing of
the door is prevented.
To effect this I provide the door with a hinge so constructed and arranged as
that on the closing of the carriage door, a gap is left between the door and the
frame.
And in order that my invention may be fully understood I have attached hereto
a sheet of illustrative drawings to which. I will now refer
Fig. 1 of the drawings indicates an elevation of a railway carriage door from
the interior of the carriage with my improvements applied.
Fig. 2 shows my improved hinge applied to a carriage door, the door being
closed:
Fig. 3 is a sectional plan view of Fig. 2 on the line A B.
Fig. 4 is a view at right angles to Figs! 2 and 3 taken in the direction of the
arrow and shows the carriage door half open.
Fig. 5 is a sectional plan of Fig. 4 on the line C D.-
Fig. 6 shows the door fully open.
Fig 7 is a sectional plan on the line E F.
• i.

Fig. 8 is a sectional plan view of the handle side of the door provided with 'a
safety gap..
In carrying my invention into effect I dispense with the usual hinges and pro-
vide the carriage door with one long hinge of any convenient length as shown
in the drawings.
The hinge consists of two metallic plates A, A¹, one of which is secured to the
door B and the other to the frame B' of the carriage by means of screws or in any
other convenient fashion. The plate A is provided with an inner projecting edge
or bead a extending along the length of the plate, the projecting edge and metallic
plate A also carrying top and bottom short cylinders b b.
The plate A is provided with a long cylinder c occupying the gap
between the two short cylinders bb. The cylinders b, b, c are bored
out and a rodd provided with a cap occupying the holes in the
cylinders, forms the axis upon which the hinge turns. The pivot of the hinge is
disposed outside the carriage door as shown more particularly in Fig. 3. The
plates A, A are provided top and bottom with flanges e which abut against each
other when the door is closed as more clearly shown in the sectional plan view
Fig. 3. The frame of the carriage is cut away so as to form a longitudinal gap
when the door is closed as shown in Figs. 1, 2 and 3.,
This gap f
p forms a safety device and prevents the accidental crushing of passengers
fingers on the closing of the door.
It will be noted more particularly from an inspection of. Figs. 3 and 5 that it is
impossible for the fingers to be trapped by the hinge as the projecting edge a on
the door plate A rolls closely in contact around the cylinder e formed, on the
plate A The improved hinge also effectually closes the gap on the, outside of
the carriage door and serves to exclude draughts.
I may also form a gap on the opposite or handle side of the door, in the thick-
and
ness of the meeting edges of the door. frame, as shown in Fig. 1. The abutting
ог
outer edges of the door and frame would serve as a draught excluder as shown in
Fig. 8, or the door might be provided with a suitable moulding or weather strip to
abut against the frame of the carriage and so close the outside of the gap.
Although I have described my invention as-being, particularly applicable to
railway carriage doors yet it will be obvious that it may be applied to the doors
of other vehicles, such as broughams,, cabs and the like. *) ** (

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:

page_text: 1) The improved means for preventing the trapping of fingers in the doors of
railway and other carriages substantially as described and shown.
2) The improved hinge for railway and other carriage doors constructed and
applied so as to allow of the provision of a safety gap to obviate the trapping of
5 fingers substantially as described and illustrated!
