Improvements in and relating to Apparatus for Securing and
Releasing Carriage Doors, Specially Applicable to Railways.
I, FREDERICK REEVES of 282 Clapham Road London S.W. Gentleman, do hereby
declare the nature of this invention to be as follows:-
My invention has for its object the prevention of accidents caused by passengers
having control over the handles of railway carriage doors. For this purpose I affix
one or more rods preferably of metal on the roofs of the carriages forming the train
and running longitudinally from end to end of the train and working on standards of
any required height, by means of grooves or other device. Projecting from the rod
or rods preferably at right angles is an arm or lever which when set in motion by the
guard as hereunder described presses against each door and effectually prevents it
being opened, and by the reverse action released.
In any required position in the guards van I affix a metal rod of suitable strength
and size (outside of the guards door opens outwards, inside if the contrary). By
means of a lever or levers connecting this rod with that on the roof, the latter is made
to revolve by the action of opening the door of the guards van, thus simultaneously
releasing all the doors in the train.
The rod or rods in the roof may be made in sections with suitable connexions to
couple and uncouple as required. By the use of my invention a present source of
danger would be avoided as the guard could not leave his van until the train was at
rest without detection.

COMPLETE SPECIFICATION.
Improvements in and relating to Apparatus for Securing and
Releasing Carriage Doors, Specially Applicable to Railways.
I, FREDERICK REEVES of 282 Clapham Road, S.W., Gentleman 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 has for its object to prevent accidents caused by passengers having
control over the handles of railway carriage doors, as also for the prevention of
accidents which so frequently occur from the doors being insecurely fastened.
In order that my invention may be better understood and carried into effect I have
appended the accompanying two sheets of drawings in which Figure 1 represents a
railway carriage to which the improved device is adapted, and Figure 2 is an end
view of same having a portion of the carriage removed to allow of the mechanism
within the guards' compartment being exposed to view. Figure 3 is a detailed view
of the actuating mechanism; Figure 4 is a type of arm employed for securing the
doors; and Figure 5 illustrates one method of coupling the rods.
The device according to my invention comprises a horizontal shaft or rod A loosely
supported upon stanchions or equivalent standards B secured to the roofs of the
carriages (. Upon said shaft A are keyed, or otherwise secured a number of pendent
arms D corresponding with the number of doors of compartments with which the
carriage is provided. To that end of the shaft A, which is within the guards' com-
partment is secured a pendent rod E loosely connected to one end of a short horizontal
arm F, the other end of which latter is pivoted to a second horizontal arı G, secured
to a vertical shaft or rod H capable of moving freely in suitable bearings I attached to
Price Bd1

page_text: the wall of the carriage. To the lower end of this vertical shaft H is adapted a short
rod K moving freely in a cleat L, adapted to the carriage door.
Now, when the door of the guards' compartment is closed, the short rod K. is held
firmly by the cleat L, and, by means of the arms F and G and pendent rod E, the
arms D, (one type of which is shown more particularly in Figure 4), are pressed
firmly against the upper parts of the doors, thus effectually preventing the accidental
or forcible opening thereof until said arms D are raised by the opening of the guards'
door. It may however happen that it is desirable to have the guards' compartment
secured against intruders during the time the train is in a station to take up
passengers, to effect which, I prefer to make the cleat L in the form of a spring catch
or equivalent, to be actuated by a key or other suitable means, so that the short rod K
may be disconnected from the guards' door during the desired interval.
In making up a train, the rods or shafts A may be coupled up in any suitable
manner, one method of such coupling being illustrated at Figure 5.
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: :-
-
First The automatic securing and releasing of the doors of railway carriages by
the opening and closing of the guards' door substantially as described and illustrated
in the accompanying drawings.
Second-In the automatic securing and releasing of the doors of railway carriages
the employment of pendent arms secured to a horizontal shaft or rod in com-
bination with the mechanism described in the guards' compartment substantially as
set forth.
