COMPLETE SPECIFICATION.
Improvements relating to the Attachment of Locks.
I, ETIENNE HAGYI-RISTIC, of Singerstrasse 13, Vienna, Austria, Doctor of Law,
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 fol-
lowing statement:―
All existing locks have the disadvantage, that they can be opened unlawfully
by means of a false key and in offices and banks during the absence of the author-
ized official.
·
This invention relates to locks which are applicable to doors, safes, chests of
drawers or the like and which prevent any unauthorized opening of the same by
means of the arrangement, that the locks themselves are easily detachable and
in the case of a change of residence or when,changing the officials of a bank or
the like the locks can be removed and taken by the owner or retiring official and
a fresh lock inserted by the successor, for which purpose in that part of the door
or the like where locks are usually fixed there are arranged suitable housings
provided with metal or the like plates or casings into which housings the locks
are arranged to fit in an easily detachable manner, but can only be inserted or
removed when the door or the like is open.
The annexed drawing shows two forms of construction of this invention.
Figs. 1 and 4 are respective longitudinal sections. Figs. 2 and 5 are elevations.
Figs. 3 and 6 are horizontal sections.
b
As can be seen from the drawing the doors or the like are provided with
housings a cut in the material thereof and formed according to the size and shape
of the lock to be inserted; these housings are provided either with a fixed metal
plate 6 Figs. 1-3 on which the lock has to lie or with a fixed casing cc (Figs. 4-6).
The plate 6 (Figs. 1-3) or the back plate of the casing c (Figs. 4-6) are pro-
vided at one, two or more places and at any suitable position with pins or bolts d d,
on which the lock with corresponding holes or perforations f f can be slid or
placed and secured thereon by any convenient device.
In the forms of construction represented in the drawings there are shown nuts
or the like g g for fixing the lock but any convenient method of fixing the lock
can be utilized.
The construction of the different locks can be very varied so that an unlimited
number of types can be produced, each of which can only be operated by its
proper key, it is only necessary, that the locks belonging to a certain category
(for instance those for doors, those for safes or for boxes) are constructed always
of similar form and size, in order that the lock can be inserted into the housinga
which are also of similar size and form.
The advantage of such safety locks is apparent in offices, banks, or the like
that where several officials have to successively or alternately undertake the same
work as an official after having given over the cash or the like to another official
takes his lock with him, whilst the other official inserts his lock and closes it,
whereby the lock cannot be opened by others and not even by the the first official
during the absence of the one having the proper key.
:

page_text: The lock is preferably made with two key holes standing at right angles to one
another (the one being vertical, the other being horizontal) and the locks are
provided with running numbers, so that in case the key is lost the lock can be
removed and exchanged for anothers whilst a new key can be made according to
the number of the lock and the lock can again be used or sold.
The forms of the locks and the necessary housings can be similar in all countries
so that the locks can be used anywhere.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1 '1..
い
An improved method of attaching locks to doors or the like in which the
housings a for the same are provided with metal plates 6 or casings c with pins
or bolts d d fixed and arranged thereon in any suitable manner the locks being
adaptable thereto by means of holes or perforations f and secured by nuts or the
like g substantially as and for the purpose set forth.
Dôted this 15th day of March 1898.
