IMPROVEMENTS IN LEVER PAD LOCKS, AND APPLICABLE ALSO TO TUMBLER PAD LOCKS
Year: 1885

page_text: I, WILLIAM HENRY SAINT AUBIN, of Bloxwich in the County of Stafford,
Mechanician and Patent Agent, do hereby declare the nature of my said invention
for "IMPROVEMENTS IN LEVER PAD LOCKS, AND APPLICABLE ALSO TO TUMBLER
PAD LOCKS" to be as follows:-
My invention consists mainly in the simplification of locks of the above
description, and this I primarily accomplish by dispensing with the bolt which
ordinarily used for securing the shackle in a locked position.
In constructing a lock according to my improvements, I form the shackle and
bolt in one and the same piece of metal, which turns and works upon a solid stud
or pin cast in the back-plate of the lock.
This bolt and shackle combined carries a lever swinging upon a stud or pin cast
thereon, and is gated in the usual way from a pin upon which the key revolves in
the centre of the lock, so that when motion is given to the bolt and shackle com-
bined, by the action of the key the lever moves with it and receives a rocking
motion. This lever has also one semi-circular rack moving upon a stud also cast
on the plate or otherwise-From this rack there is another one at right-angles
which passes over the stud on the plate in the motion of locking and unlocking,
and if the key be taken out of the lock when unlocked, or the shackle open, the
shackle will remain in that position, but when the lock is applied to a staple, by
simply pressing the shackle to with the thumb and finger, the lock is securely
locked without the aid of the key, thus it is an automatic lock. I do not however
strictly confine myself to the precise details herein described, as the same may be
open to some slight modification.

Tumbler Pad Locks.
I, WILLIAM HENRY SAINT AUBIN of Bloxwich in the County of Stafford,
Mechanician and Patent Agent do hereby declare the nature of my invention for
"IMPROVEMENTS IN LEVER PAD LOCKS AND APPLICABLE ALSO TO TUMBLER PAD
Locks" and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
.
My invention consists mainly in the simplification of locks of the above
description, and this I primarily accomplish by dispensing with the bolt which
is ordinarily used for securing the shackle in a locked position..
In constructing a lock according to my improvement, I form the shackle and
bolt-Fig. 3-in one and the same piece of metal, which turns and works upon a
solid stud or pin-c Fig. 1-cast in the back plate of the lock.
This bolt and shackle combined carries a lever--Fig. 4-swinging upon a stud or
pin-b Fig. 1 cast thereon, and gated in the usual way from a pin-a Fig. 1-
upon which the key revolves in the centre of the lock, so that when motion is
given to the bolt and shackle combined, by the action of the key, the lever moves
with it-see dotted lines Fig. 1-and receives a rocking motion-This lever-
Fig. 4 has only one semicircular rack-g Fig. 1-moving upon a stud―d Fig. 1-
also cast in the plate or otherwise-From this rack there is another one at right-
angles-h Fig. 1-which passes over the stud-d-in the plate in the motion of
locking and unlocking, and if the key be taken out of the lock when unlocked, or
the shackle open, the shackle will remain in that position, but when the lock is
applied to a staple, by simply pressing the shackle to with the thumb and finger,
the lock is securely locked without the aid of the key, thus it is an automatic lock.
When thus locked the end of the shackle abuts against a solid block cast upon
the inner side of the cap or cover of the lock, thus making it secure against the use
of the burglars bar or jemmy.
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 improved construction of Pad Locks with automatic locking action
substantially as herein before described and illustrated by Fig. 1-of the drawings.
2-The forming of the bolt and shackle in one and the same piece substantially
as hereinbefore described and illustrated by Fig. 3-of the drawings.
