Improvements in Appliances connected with the Doors of Railway
Carriages and other Vehicles.
I CHARLES THOMPSON of 2 St. James Place, Otley Road, Baildon, in the
County of York, Mill, Furnisher do hereby declare the nature of this invention
to be as follows:-'
This invention-relates to improvements in appliances to be applied to the doors
of railway carriages, cabs and other vehicles, the object being to prevent the
fingers, clothing, or other articles being trapped between the door and the door
jamb when the door is-closed.
According to this invention I hinge to the inside of each of the door jambs or
checks a strip or fath of wood. To the upper end of each lath is fixed a cranked
finger, and these fingers are connected together by means of a spiral spring which
tends to draw them towards one another. Fast to one of the cranked fingers is a
leather or steel band which passing over a small pulley is connected to the cranked
finger on the other lath and thence passing. over a guide pulley is fixed to the
outside of the door.
-
-.
When the door is opened and turned back the leather or steel band is slackened
and the spiral spring pulling the two cranked fingers towards one another the laths
are turned on their hinges and so fold close to the face of the door jamb or check.
"When the door is closed the leather or steel band pulls on the cranked fingers,
extends the spring, and the laths are turned inwards and the fingers, or any article
which may be against or near the face of the door jamb is or are pushed away by
the laths which when the door is properly closed lie close against the inside of the
door, and over and completely cover the space or opening between the door and
door jamb.

COMPLETE SPECIFICATION.
Improvements in Appliances connected with the Doors of Railway
Carriages and other Vehicles.
I, CHARLES. THOMPSON, of 2 St. James Place, Otley Road, Baildon, in the
County of York, Mill Furnisher, 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 :-
This invention relates to improvements in appliances to be applied to the doors
of railway carriages, cabs, and other vehicles, and doors generally, the object being
to prevent the fingers,, elothing, or other articles being trapped between the door
and the door jamb when the door is closed, and the invention consists of laths or
strips of wood-hinged to the inside of each cheek or jamb of the door, and extending

page_text: from top to bottom of the door. At the top of each strip or lath is a cranked
finger, and these fingers are connected by a spiral spring, which when the door is
open, turns the strips or laths on their hinges, and moves them close to the inside
of the door jamb or cheek. When the door is closed, a chain, strap, or band, fast
to the door and to the cranked fingers, pulls. the latter, and extends the spiral
spring, and the laths are turned inwards, and the fingers or any article against or
near the door jamb or cheek, is or are thereby pushed away before the door is
properly closed.
"
Such being the nature and object of my said invention, the following is a
complete description of same, reference being had to the accompanying, drawings,
Which
10°
Fig. 1 is a front elevation of the inside of a railway carriage door (closed) having
my improved appliances applied thereto.
. 1
Fig. 2 is a similar view to Fig. 1, but the door is shewn open.
Fig. 3 is a plan view of Figs. 1 and 2, the door being shewn partly open.
Fig. 4 is a sectional plan view, on line A. B. of Fig. 2.
Fig. 5 is a sectional plan view, on line A. B. of Fig. 1.
According to this invention, I hinge at 1. 1. to the inside of each of the door
jambs or cheeks 2. 2, a strip or lath of wood 3. To the upper end of each lath 3
is fixed a cranked metal finger 4, and these fingers 4. 4 are connected together by
means of a spiral spring 5, which tends to draw them towards one another.
Fast to one of the cranked fingers 4, is a leather or steel band 6, which, after
passing over a small pulley 7, is connected to the cranked finger 4 on the lath 3 at
the opposite side of the door, and thence passing over a guide pulley 8, is fixed to
the outside of the door 9.
Instead of the strap or band 6 passing over the pulley 8, and to the outside of
the door 9, I prefer that the end of the band or strap 6-should: terminate in, or be
attached to a chain 10 (as being more durable) one end of which chain 10 is fixed
to the outside of the door 9 (see Fig. 3).
When the door 9 is opened and turned back (see Figs. 2, 3, and 4), the leather
or steel band 6 is slackened, and the spiral spring 5 pulling the two cranked
fingers 4. 4 towards one another, the laths 3 are turned on their hinges 1. 1, and so
fold close to the inner face 2 (see Fig. 4) of the door jamb or cheek 2. When the
door 9 is closed (see Figs. 1 and 5) the leather or steel band 6 pulls the cranked
fingers 4. 4 in opposite directions, and extends the spring 5, and the laths 3. 3 are
turned inwards, and the fingers or any article which may be against or near the
face of the door jamb, i.e. in the angle or space between the door 9 and the door
iamb or cheek 2, is, or are pushed away by the laths 3. 3, which, when the door 9
is properly closed, lie close against the inside of the door, and over and completely
cover the space or opening between the door 9 and door jamb 2 (see Figs. 1
and 5).
The pulleys 7:8, spiral spring 5, and part of the cranked fingers 4. 4 are enclosed
in a box or casing 12 fixed above the door 9; the lower parts of the fingers 4. 4
passing through slots 13. 13 in the bottom of the box 12, to the top of the door 9,
to which they are fixed by screws.
The laths or strips 3 being over the space between the edges of the door 9, and
the door jamb or cheek 2 (when the door is closed) draughts of air or dust are
'prevented passing through such space.
Having now particularly described and ascertained the nature and object of the
said invention, and in what manner the same is to be performed, I declare that
what I claim is :-
1. The laths or strips of wood 3. 3, cranked fingers 4. 4, spiral spring 5, leather
or steel band or strap 6, connected to the door 9, as and for the purpose herein
described, and substantially as illustrated by Figs. 1, 2 and 3 of the accompanying
drawings.

page_text: 2. The laths or strips of wood 3. 3, cranked fingers 4. 4, operated by the door 9
for the purpose herein fully described and substantially as illustrated by Figs. 1, 2
and 3 of the annexed drawings.
