PROVISIONAL SPECIFICATION.
Improvements in the method of and means for Locking and Unlocking
the Doors of Railway and other Carriages.
We, HENRY COTTON HARDING, of 22, Lindley Street, Holgate, York, Fitter,
THOMAS EMERSON PICKERING, of Garforth, near Leeds, Farmer, and FRED
BUCKLEY, of 57, Northgate, Halifax, Wine and Spirit Merchant, all in the
County of York, do hereby declare the nature of this invention to be as
follows:-
The object of our invention is to lock and unlock railway and other carriage
doors, and so prevent accidents.
When the carriages are in motion the doors are locked, and as soon as they
come to a standstill and the brake is applied they are automatically unlocked,
or if required they can be locked or unlocked from the outside by guard or
porter.
In connection with the ordinary brake upon the end of the thrust rod, we
connect a link to an arm on the underside of a cross shaft at the front, rear,
or other part of the carriage. At each end or side connected to the cross shaft
is an arm or lever connected to a long horizontal rod running the length of the
carriage. From this rod near each door is connected a vertical rod, and a spring
rod or bolt, the end of the spring rod or bolt having an incline on one side,
so that on a door being shut it automatically locks.
The spring rod is slotted at its connection with the vertical rod, to allow
of an independent movement when shutting any one door. Any suitable form
of spring may be used in connection with the spring rod.
On the brake being applied the long rod is drawn back, so operating the

handle may be fixed by which the doors of each carriage can

addition to the ordinary carriage handles.
If one side only of the doors are required to be operated, the arm connecting
the long lever with the shaft is disconnected therefrom by means of a pin or
cotter, then one side only operates.

manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:―

DESCRIPTION OF DRAWINGS.
Fig. 1 is a side elevation in section of a railway carriage with our improve-
ments applied.
Fig. 2 is a sectional plan through the line A, B of Fig. 1.
In connection with the ordinary brake upon the end of the thrust rod C, we
connect a link or lever 1 pivotted upon a stud E supported by a bracket F,
this lever D has preferably arms G, these arms G being connected to the
brake H upon each side of the wheels J by connecting rods K, so that upon
the thrust rod C being moved into the position shown in dotted lines, the
brake H is immediately applied to both sides of the wheels.
Also connected to this link or lever D is another connecting rod L, whose
other end is pivotted or hinged to another arm M upon a cross shaft N, at front,
rear or other part of the carriage; at each end of this cross shaft N, are mounted
suitable arms or links P, connected to a long horizontal rod or bar R upon each
side of the carriage, and running the length of same.
From this rod R near each door is connected a vertical rod S, and a spring
rod or bolt T, the end of the spring rod or bolt T having an incline, or is
rounded upon one side to push back the bolt T, so that on a door being shut
it automatically locks or secures the same.
The spring rod T is slotted at its connection with the vertical rod S, to allow
of an independent movement when shutting any one door. Any suitable form
of spring may be used in connection with the spring rod.
On the brake being applied the thrust rod C is moved into the position shown
in dotted lines, operating the connecting rod D, arm or rod L upon the cross
rod N, arms or links P, drawing back the long horizontal sliding rod R, this
rod R in turn acting on the levers S withdraws the bolts T and unlocks the
doors.
Immediately the brake H is taken off (usually when about to start the train),
the thrust rod C on returning to its normal position, simultaneously returns
the rod R and its operating mechanism to their original positions.
When desiring to lock or unlock the doors of each or any one carriage, we
provide a handle V upon the cross rod or rocking shaft N, so that the porter
or guard may operate the rod R from outside when desired.
This locking arrangement is in addition to the ordinary carriage handles.
If one side only of the doors are required to be operated, the arm P con-

page_text: necting the long lever or rod R with the cross shaft N is disconnected therefrom
by means of a pin or cotter W, then one side only operates.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
what we claim is:-
1. In locking and unlocking apparatus for railway carriages, the combination
of lever D, connecting rod L, arms M and P upon rocking or cross shaft N,
longitudinal rod R, and lever S for actuating the spring bolt T, all operated
each time the brake is put on or taken off, in the manner and for the purposes
set forth.
2. In locking and unlocking apparatus for railway carriages, the combination
of lever D, connecting rod L, arms M and P upon cross shaft N, longitudinal
rod R, lever S, and handle V with or without pin W, operated and operating
in the manner and for the purposes set forth.
