Improvements in Safe Locks.
I, ROBERT TAYLOR, of 123 Arlington Street, New North Road, Islington, in
the County of Middlesex, Locksmith, do hereby declare the nature of this
invention to be as follows:-
The object of the invention is to facilitate the closing and locking of the doors
of iron safes by the use of a spring or self-acting lock and without the necessity
for using the key. The levers and bolt of the self-acting lock are actuated by the
key for opening or unlocking the said self-acting lock, the bolt, when such action is
completed, being held back by a self-acting dog; the key is then, if desired,
withdrawn from the lock. Then the large bolts and their strap which lock or
secure the door to the safe are thrown back by the handle on the outside of
the door, when a shoulder or projection on the said bolt strap or a suitable moving
part of the mechanism, will strike the self-acting dog in the lock and release the
lock bolt, but only to a small extent as it is stopped by the strap of the large bolt
or by other suitable means until the strap and large bolts are again thrown by the
handle for locking the door, when the self acting lock bolt will shoot fully home
and its levers will fall into position thereby locking or securing the door in its shut
position.

COMPLETE SPECIFICATION.
Improvements in Safe Locks.
I, ROBERT TAYLOR, of 123 Arlington Street, New North Road, Islington, in
the County of Middlesex, Locksmith, 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 :-
The object of the invention is to facilitate the closing and locking of the doors
of iron safes by the use of a spring or self-acting lock and without the necessity
for using the key.
The levers and belt of the self-acting lock are actuated by the key for opening
or unlocking the said self-acting lock, the bolt, when such action is completed,
being held back by a self-acting dog; the key is then, if desired, withdrawn from
the lock. Then the large bolts and their strap or straps which lock or secure the
door to the safe, are thrown back by the handle on the outside of the door, when a
shoulder or projection on the said bolt strap, or a suitable moving part of the
mechanism, will strike the self-acting dog in the lock and release the lock bolt, but
only to a small extent as it is stopped by the strap of the large bolts or by other
suitable means until the strap and large bolts are again thrown by the handle for
locking the door, when the self-acting lock bolt will shoot fully home and its
levers will fall into position, thereby locking or securing the door in its shut
Dosition."

page_text: My invention is illustrated in the accompanying drawings, in which :-
Fig. 1 is a view of the inside of a safe door provided with locking arrangements
constructed according to my invention, the inner covering plate thereof having
been removed to enable the parts to be seen, and showing the main bolts in their
locked position.
Fig. 2 is a similar view of parts shown in Fig. 1 but showing the main bolts in
their unlocked position, and
Fig. 3 is a front view of the self-acting lock with its parts in their locking
position and with the front plate removed.
A is the self-acting lock; the bolt a, levers b and other operative and security
parts thereof are constructed as shown or in any other approved method.
The levers band bolt a are actuated by the key c for opening or unlocking the
lock A, the bolt a, when such action is completed, being held back by a self-acting
dog or catch d, which is acted upon by a spring d to cause its outer end to be
pressed constantly towards the bolt a in readiness to hold the same back when
unlocked or drawn back by the key c. I also, for extra security, employ a number
of spring levers e mounted on the stud e¹ and bearing by their ends against the
follower f, so that in the event of one of the springs e² breaking, there will be
sufficient power still left in the other spring levers whose springs are still intact to
secure the correct action of the bolt a.
When the lock A is unlocked, the key c can, if desired, be withdrawn from
the lock.
The large or main bolts g, as shown in the drawings, are mounted on axial
studs and are all simultaneously operated by studs on the straps h working
within slotted openings 2 in the bolts g. The straps h are guided in their motion
by fixed studs i passing through slots in the straps; one strap is formed with
teeth which are taken into by a toothed segment operated by a handle fixed
on the axis thereof. The two straps are connected together by levers k mounted
on axes of motion so that they move in unison on the handle being turned. The
toothed segment j has a tail piece j³ which is acted upon by a spring lever I to assist
the locking action.
When the lock A is unlocked and the large or main bolts g and their straps are
thrown back by the handle on the outside of the door, a shoulder *, or it might be
a projection, on one of the said straps, or other suitable moving part of the
mechanism, will strike the self-acting dog or catch d in the small lock A and
thereby release the bolt a, but the latter will move forward to only a small extent
as it is stopped by coming against the edge of one of the straps h, which, as shown,
is slightly cut away to receive it; the bolt a remains in this position until the
straps and large or main bolts 9 are again thrown by the handle for locking the
door, when the self-acting lock bolt a will shoot fully home and its levers b will fall
into position to secure the bolt a, thereby locking or securing the door in its shut
position.
It will be evident that various modifications may be made in the construction
and arrangement of the parts without departing from the peculiar character of my
invention.
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:-
1. In safe locks, the peculiar combination and arrangement of parts, substan-
tially as herein shown and described and for the purpose stated.
2. In safe locks, the combination with the main bolt and parts actuating the
same, of a self-acting lock to secure the main bolts in their locked position, a self-
acting dog or catch in connection with such self-acting lock to retain the security
bolt in its unlocked position until the main bolts are unlocked, and a moving part
connected with the main bolts to act upon the self-acting dog or catch to release
the security bolt therefrom, the said security bolt being prevented from shooting

page_text: fully home by coming against a strap or other moving part connected with the
main bolts until the latter are moved to their locked position, when the security
bolt shoots fully home and secures the main bolts in their locked position,
substantially as herein shown and described.
