PROVISIONAL SPECIFICATION left by the said Herbert John Haddan at

HERBERT JOHN HADDAN, of the Firm of Herbert and Company, Solicitors of
Patents, of 67, Strand, in the City of Westminster, Civil Engineer. "IMPROVE
MENTS IN LOCKING DEVICES." A communication from abroad by Joseph Thomer,
of Vienna, and Franz Köházy, of Kaschau, both in the Austro-Hungarian Empire.
This Invention relates to "seal" locks, and the primary object is to replace the
usual sealing with lead of railway-carriages, bullion vans, transport boxes, jewel
chests, mail hoxes, &c., by a more effective and reliable fastening device in com-
bination with a controlling mechanism; but the improvements may be used for
other purposes.
The new locking devices render it possible to shut the carriage
or other doors in a perfectly safe manner during an interrupted unloading or
loading without sealing said doors with lead, which at present is impossible. The
improvements consist of a lock, provided equally on each carriage or other door,
and of a key, to be kept by an authorized officer only. This key serves at the
same time to mark the leads; to each key is attached a set of types with the name
of the station or destination of the carriage or box and the cyphers of the months
and days. The said lock is fixed on the carriage or other door, and is provided.
with a hinged hook. For shutting the door the hook is lifted from its horizontal.
position, the door is closed, and the hook pressed down with the hand, so that a
projection of the hook falls into an eye provided on the side of the carriage or box.
The lock consists of a double case, a hinged snapplate, a tumbler acted on by spiral
springs, a punching device, a stop pin, an arrangement for holding and securing
the lead. The key is made to serve as a lever, and also a controlling mechanism;
the various parts are made of metal.

HERBERT JOHN HADDAN, of the Firm of Herbert and Company, Solicitors of
Patents, of 67, Strand, in the City of Westminster, Civil Engineer. "IMPROVE-
-MENTS IN LOCKING. DEVICES." A communication from abroad by Joseph Thomer,
of Vienna, and Franz Köházy, of Kaschau, both in the Austro-Hungarian Empire.
The object of this Invention is to replace the usual sealing with lead of railway
carriages by a more effective and more reliable shutting device in combination with
a controlling mechanism.
This shutting device consists of a lock screwed on the carriage door and of a key
kept at every railway station. With the lock is further combined a control-mark
or indicator for recording whether and where the waggon has been shut, and
whether, when, and where the waggon has been opened.
In describing the Invention reference will be had to the accompanying Drawings,
in which Fig. 1 is a front view of the lock; Figs. 2a and 2b internal views; Fig. 3,
a side view; Fig. 4, a longitudinal section through the line A, A¹, in Fig. 3; Fig. 5
is a longitudinal section through the line B, B', in Fig. 1; Fig. 6 represents the
key with its punching device; Fig. 7 represents a double mark as used for this
lock; Fig. 8 is a transverse section through the line C, C', in Fig. 1. In all
figures similar parts are marked by the same letters of reference.
The lock consists of a case of cast iron or other suitable material; its front part
is accessible from without, and serves for the reception of the control-mark; its rear
part is somewhat larger and contains two different locking appliances, one of which
serves for closing the waggon, whilst by the other the mark-case is shut. The
latter consists of a sliding catch controlled by a spiral springs of a hinged
movable plate c with its crook f, which enters the sliding catch r when the plate c
is pressed against the lock. The carriage lock consists, 1, of a closing hook a, by
the movements of which two different functions are performed; on the one hand
by simply depressing the hook the waggon is shut, on the other hand on raising
the said hook the hinged plate c is freed by the disengagement of the crook f from
the catch, whereby the mark case is opened; 2, of a tumbler n-p acted upon by'
four strong spiral springs t; 3, of a pin o serving as a guide for the tumbler and as
a punch for the control-mark; 4, of a stopping device v, by which the shutting
device can be temporarily put out of action.
The key, Fig. 6, is constructed to act as a lever, so as to overcome the resistance
of the spiral springs t when opening the lock.; it marks or punches at the same time
the enclosed controlmark. The lever arrangement of the key consists, 1, of a hook
hh-which-engages-into the shoulders i, il, m, m2, of the lock; 2, of a lever k, by
which the necessary pressure may be excerted; 3, of a punch 7, guided by two cheeks
and receiving the types of the station and of the dates for marking the control
mark.
To shut the waggon the hook a of the lock fixed on the waggon door is turned
down by hand into a horizontal position, so that one of its toes b or b¹ engages
into the ring provided on the side of the waggon; thereby the waggon is shut,
because that part of the hook a which lies within the lock is held fast by the
tumbler n, p..
The control is established by placing upon the recesses provided at the inside of
the hinged plate ca mark d, made of paste board or other suitable material, so as
to cover the openings e and e'; and then the hinged plate is turned upwards and
pressed against the lock until the crook f of the said hinged plate catches into the
sliding catch r, whereby the marking case is closed.
Now the hook a and the hinged plate c cannot be thrown up without using the
said key, Fig. 6. By placing the hook h, h², of the key upon the upper shoulders

page_text: i and of the lock, and then pressing down the lever k, the punch / marks the
upper half of the control mark with the name of the station and date, whereby it
is made visible when and where the waggon has been shut.
To open the carriage the key is placed upon the lower shoulders m, m³, of the
lock and the lever is pressed down, thereby the punch is pressed against the
lower half of the control-mark and impresses on it the types of the station and date,
whilst the pin o perforates the same. At the same time and by the same movement
of the lever k the movable cylinder n, which is pressed forward by the spiral
springs t, is now pressed backward, whereby the tumbler p is removed from the
hook a, so that the latter may be raised and the waggon opened.
By raising the hook a the catch is also raised, so as to disengage the hinged
plate. When the latter is turned downwards the pasteboard marked with the
names of the shutting and opening-station and with the respective dates can be
taken out and replaced by a new one.
In this manner is recorded where and when the waggon has been shut, and also
where and when the same has been opened.
To allow of this lock being used like an ordinary lock provision is made to set
the described locking device out of action by simply inserting the arresting or
stop pin v, as shown in Fig. 1, after which the hook a is free to be raised or let
down and hooked into the ring as in any other waggon not furnished with this
lock.
It is impossible to remove the stan nin without using the box
CLAIMS.
1. The general arrangement and construction of the shutting device for railway
carriages consisting of the hook a, the lock, and the key.

on by spiral springs t with the case containing the control mark and, the sliding
catch r engaging into the crook f of the hinged plate c.
3. The stop pin v for putting the shutting device out of action.
4. The key in combination with the lever arrangement h, h¹, and k and a

The whole substantially as shown and described and to the purpose specified.
In witness whereof, I, the said Herbert John Haddan, have hereunto set
