PROVISIONAL SPECIFICATION.
An Improved Fastening for Railway Carriage Doors.
I, CHARLES CLARKE, Hat Manufacturer, of 22 Tylor Street, Luton, in
the County of Bedfordshire, do hereby declare the nature of this invention to be as
follows:-
My invention relates to an improved fastening for railway carriage doors, which
consists of mechanism worked by levers and bolts, to lock the whole of the doors
in a railway carriage at once, operated on by any of the servants usually employed
by railway companies.
The object of my invention is to prevent the doors of any railway carriage being
opened by any of the passengers when the carriages are in motion.
This invention is constructed with a horizontal bar working in a slot inside the
framework of the carriage, on each side of the said carriage, and to each of the
aforesaid bars I place vertical rods pivoted or otherwise adjoining each fastening of
each of the doors. At the top of the vertical rods 1 pivot a small bar or bolt
(with a spiral spring attached), for the purpose of fixing the catch of the ordinary
fastening; or the bolt may be independently and shoot from the jamb into the door
frame when the door is closed, by the pull of each horizontal bar; these aforesaid
bars may be coupled together and kept at tension when the doors are bolted,
but when released the springs force the bolts from the door frame of each door.
It will be understood that the foregoing is given by way of illustration only and
that the shapes, materials, and proportions of the various parts may be varied in
many ways within the scope of my invention.

COMPLETE SPECIFICATION.
An Improved Fastening for Railway Carriage Doors.
1, CHARLES CLARKE, of 22 Tylor Street, Luton, in the County of Bedford-
shire, Hat Manufacturer, 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:-
My invention relates to an improved fastening for railway carriage doors, which
consists of mechanism worked by levers and bolts, to lock the whole of the doors in
a railway carriage at once, operated on by any of the servants usually employed by
railway companies.
The object of my invention is to prevent the doors of any railway carriage being
opened by any of the passengers when the carriages are in motion.
This invention is constructed with a horizontal bar working in slots outside the
framework or bed of the carriage, on each side of the said carriage, and to
each of the aforesaid bars I place vertical rods pivoted or otherwise adjoining
each fastening of each of the doors. At the top of the vertical rods I pivot
a small bar or bolt (with a spring attached) for the purpose of the bolt shooting
from the jamb into the door frame when the door is closed, by the pull of each
horizontal bar; these aforesaid bars may be coupled together and kept at tension
when the doors are bolted, but when released the springs force the bolts from the
door frame of each door.

page_text: And in order that my invention may be thoroughly understood, I now proceed
to describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon.
The illustration is a front view of one of the bolts fixed in the door jamb and
connected by a vertical rod to the horizontal bar and the lever for shooting or
releasing the bolts. This figure is broken off for want of space. The dotted lines
indicate the movements when released and describes the action by the power of the
spring in each bolt box.
"
In a box e with a division I place a bolt a through slots, and in the box e 1 fix a
spring done end of the said spring fitting into a notch c in the bolt a. The box e
is screwed into a recess in the door jamb b. To each door 1 provide the
aforesaid bolt and box in the door jamb as before described. To each bolt I attach
a vertical rod or bar a pivoted in the box and the bolt a down to the horizontal
sliding bar. Each pivot pin or head is marked throughout the illustration.
The vertical roly may be curved, cranked or of any other suitable shape. On the
side of the carriage bed place a horizontal sliding bar i working in slots 11, this
said bar is provided with the usual screw couplings at each end of each carriage so
as to be connected with the lever mechanism in the brake van. In the brake van
j
I fix a cranked lover with a handle &, this said lever having a slot at the base
and is pivoted at to the sliding bar. The lever is pivoted to a raised block q
with a pallo which falls in a notch p, the said pall being released from the notch
by the bar and handle ».

It will be understood that the foregoing is given by way of illustration only and
that the shapes, materials and proportions of the various parts may be varied in
many ways within the scope of my invention.
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 :-
:-
and
1. The combination of the bolt a spring d box e and division h with bar
pivots and sliding bar and slot plates for locking doors in a railway carriage,
substantially as herein described and according to the accompanying drawings.
2. The combination of the lever slot r pallo bar a handles and m with
pivots, and block with notch P for the purpose of operating the bolts in a
carriage or in a number of carriages, substantially as herein described and according
to the accompanying drawing.
3. The combination of the various parts to be constructed of any shape or of any
materials substantially for the purpose specified.
