Complete Specification Left, 30th June, 1898-Accepted, 30th July, 1898
I, JONAS SOLOMON, of 24, Whitechapel, Liverpool, in the County of Lancaster,
Safe Dealer, do hereby declare the nature of this invention to be as follows:-
This invention relates to locks more particularly for safes and strong rooms
but is applicable for any lock required to be secure against burglary.
The invention consists essentially in combining together, two or more inde-
pendent locks of any suitable known construction to form a multiple lock having
a single keyhole, the locks being placed and secured one over the other so that
their keyholes register.
A multiple lock is thus produced requiring each component lock to be inde-
pendently manipulated through one keyhole common to all, so that if one lock
be forcibly damaged the remaining component lock or locks still remain intact
to offer further obstruction to the burglar.
In carrying the invention into effect I take two or more locks preferably having
each a different arrangement of wards or tumblers so as to require each a different
key, and I place them one over the other with their keyholes registering as before
stated. Between each lock I place a steel plate, or any known arrangement of
combined plates such as of steel and softer metal to form guard-plates adapted to
turn a drill, and I secure the whole together by screws or in other suitable
manner.
In order to open or lock such a combined or multiple lock, it is necessary to
actuate each component lock separately by means of its respective key. For the
purpose of convenience however, and in order to avoid any possibility of the com-
ponent locks not being all opened or all locked, I prefer to combine the different
webs or bits of the several keys on to a single stem so as to form a single key
with multiple bits whereby the multiple lock may be actuated by a
single insertion of the key, the bits being placed at suitable intervals along the
stem so that each bit will engage its respective component lock when the key
is inserted in the key-hole.

I, JONAS SOLOMON, of 24, Whitechapel, Liverpool, in the County of Lancaster,
Safe Dealer, 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:-
This invention relates to locks more particularly for safes and strong rooms
but is applicable for any lock required to be secure against burglary.

pendent locks of any suitable known construction to form a multiple lock having

A multiple lock is thus produced requiring each component lock to be inde-
pendently manipulated through one keyhole common to all, so that if one lock
be forcibly damaged the remaining component lock or locks still remain intact
to offer further obstruction to the burglar.
In carrying the invention into effect, I take two or more locks preferably having
each a different arrangement of wards or tumblers so as to require each a different
key, and I place them one over the other with their keyholes registering as before
stated. Between each lock and the next I place a steel plate, or any known arrange-
ment of combined plates such as of steel and softer.metal to form guard-plates
adapted to turn a drill, and I secure the whole together by screws or in other suit-
able manner. The guard plates may of course be omitted in some cases, as
desired.
'
In the accompanying drawings a multiple lock consisting of two component
locks for example is shown in Figure 1 in isometrical projection.
A and B are the two component locks secured together with their key-holes
registering to form a single keyhole C. D is a guard plate between the two locks
for greater security, and which is provided with a keyhole registering with those
of the locks so as to allow of a key inserted in C being pushed through into the
lock A.
In order to open or lock such a combined or multiple lock, it is necessary to
actuate each component lock separately by means of its respective key, the keys
being inserted successively in the keyhole C. For the purpose of convenience
however, and in order to avoid any possibility of the component locks not being all
opened or all locked, I prefer to combine the different webs or bits of the several
keys on to a single stem so as to form a single key with multiple bits as shown in
Figure 2, whereby the multiple lock may be actuated by a single insertion of the
key, the bits being placed at suitable intervals along the stem so that each bit will
engage its respective component lock when the key is inserted in the keyhole C.
In the example shown in the drawings, the bit a will engage the component
lock A and the bit b the component lock B.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. A lock consisting of two or more independent locks placed and secured one
over the other with their keyholes registering so as to form a multiple lock baving
a single keyhole common to all the component locks, substantially as and for the
purpose hereinbefore set forth.
2. In a multiple lock such as described, the combination with two or more com-
ponent locks placed and secured together with their keyholes registering, of a
guard plate secured between each lock and the next and provided with a keyhole
to register with those of the component locks, substantially as hereinbefore
described.
3. A key having two or more bits or webs formed on a single stem adapted to
actuate simultaneously a number of independent locks combined together to form
a multiple lock with a single keyhole, substantially as herein before described.
