DAVID DYE, Engineer, No. One Hundred and Eight, Divison Road, Hessle
Road, City of Hull, do hereby declare the nature of this invention to be as follows:-
It consists of a number of slides slots or catches and springs inside and on the
outside knobs or handles which when moved and manipulated (not turned)
releases three bolts so that the lock is open. There are nine knobs or handles on
the outside which can be moved (not turned) consecutively. There are also
a key hole and key. These slides slots or catches springs and devices
can be augmented to any number. Thus assuming that three locking bolts
or handles
are controlled by eight devices and a key and the nine knobs
which is supposed to be A, B, C, D, E, F, G, H, I, then for unlocking the
bolts B, H, F, has to be moved (not turned) to release E, when E is moved (not
turned) the keyhole is then disclosed for to insert the key and when turned
releases the centre bolt. B, C, and A, being moved (not turned) releases the
second bolt, by moving (not turning) H, I, G, releases the third bolt. From this
it will be seen that the safety of the lock against unauthorised persons opening it
the number of
will depend on the number of permutations possible with
controlling devices of which the lock is composed so that the chances against
unauthorised opening are very great.
DAVID DYE, Engineer, No. One Hundred and Eight, Division Road, Hessle
Road, City of Hull, 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 :-
It consists of a number of slides slots or catches and springs inside and on the
outside knobs or handles which when moved and manipulated (not turned)
releases three bolts so that the lock is open. There are nine knobs or handles on
the outside which can be moved (not turned) consecutively there are also a
keyhole and key. These slides slots or catches springs and devices can be
augmented to any number. Thus assuming that three locking bolts are controlled
by eight devices and a key, and the nine knobs or handles which is supposed to
be a, b, c, d, e, f, g, h, i. Then for unlocking the bolts b, h, f, and e, has to
be moved (not turned) the keyhole is then disclosed for to insert the key and

page_text: when turned releases the centre bolt. b, c, and a being moved (not turned)
releases the second bolt by moving (not turning) h, i, g, releases the third bolt;
from this it will be seen that the safety of the lock against unauthorized persons
opening it will depend on the number of permutations possible with the number
of controlling devices, of which the lock is composed so that the chances against
unauthorized opening are very great. To close the lock the centre bolt is self
closing; the second and third bolts are also self closing, but may be assisted in
doing so, by moving and 9. By moving band h, the keyhole is closed and
now by moving i and c, to notch into the second and third bolts the lock is
completely closed.
DRAWINGS.
Fig. 1 represents the outside of the front part of the lock shewing the knobs or
handles and lettered a, b, c, d, e, f, g, h, i.
Fig. 2 shews a front section or part of the lock with part of the bars where
studs are affixed.
Fig. 3 represents the bar or outside of the lock where the three studs are
attached, which studs enter the lock to be fastened with the three bolts.
Fig. 4 represents one of the studs attached to Fig. 3.
Fig. 5 represents the interior of the lock showing the slides slots or catches
and springs. Being marked, with the letters a, b, c, e, f, g, h, i, now the slots
or catches b, h, and f fastens e, then by sliding b to the left, h to the right,
and to the left, then e, can be slid downwards which discloses the keyhole b,
and h, then goes into their first position 6, being slid to the left takes the catch
or slot out of c, then c being slid downwards takes the slot or catch, out of a.
a being released has to be slid to the left, and then the bolt is out of the stud,
8 being slid to the right takes the catch or slot, out of i then i being slid
downwards takes the catch or slot out of g. It being released, has to be slid
to the right and then the bolt is out of the stud and by turning the key
takes the centre bolt out of the stud when the lock is entirely open.
When I work the two outside bolts by the sliding kuobs, I keep them
retracted by band, whilst the mid bolt is kept retracted by the angle of the
key.
I may also use more than three bolts.
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. The combination of sliding bars either notching into one another or pressing
against one another and preventing the unlocking of the three bolts as shown
and described.
2. The combination of sliding bars either notching into one another or pressing
against one another and preventing the opening of key hole or holes as shewn and
described.
3. The combination of sliding bars moved either by the outside knobs or by two
or more handles or keys, which release the sliding bars from their several notches,
opening the one or more keyholes and allowing the three bolts to be unlocked.
