PROVISIONAL SPECIFICATION.
Improvements in Pad Locks.
I, AMOS VAUGHAN of Union Street Willenhall in the County of Stafford Pad
Lock Manufacturer do hereby declare the nature of this invention to be as
follows:-
My improvements in Pad Locks consists. Firstly in dispensing with the ordinary
shackle, in lieu of which I employ a loose staple which I insert in a slot in the
upper part or rim of the lock case, the interior of which contains a bolt swinging
upon a stump in the lower part of the lock and crossing the slot in the upper part;
which bolt enters the loose staple and thereby secures the lock to the said loose staple.
Secondly, I employ a tumbler swinging upon a stump on the surface of the bolt which
is gated to the key in a space about the centre of the same, the said tumbler falling
against a stump in the back plate of the lock as the bolt is shot to the right or
left, and is actuated by a spring fitting upon the same stump upon which the bolt
swings.
Inasmuch as the invention may be open to some minor modifications without
departing from the main principle, I desire it to be understood that I do not strictly
confine myself to the precise details herein specified.

COMPLETE SPECIFICATION.
Improvements in Pad Locks.
I, AMOS VAUGHAN of Union Street Willenhall in the County of Stafford, Pad
Lock Manufacturer, 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:→
My improvements in Pad Locks consists firstly in dispensing with the ordinary
shackle, in lieu of which I employ a loose staple-A-Fig. 1-which I insert in a
slot-B-in the upper part or rim of the lock case-C-the interior of which
contains a bolt-D-swinging upon a stump-E-in the lower part of the lock, and
crossing the slot-B-in the upper part, which bolt enters the loose staple and
thereby secures the lock to the said loose staple.
Secondly, I employ a tumbler-F-swinging upon a stamp-G-on the surface of
the bolt which is gated to the key in a space-H-about the centre of the same, the
said tumbler falling against a stump-I-in the back plate of the lock as the bolt is
shot to the right or left and is actuated by a spring-J-fitting upon the same
stump-G-upon which the bolt swings.
As a simple modification I also construct a lock-Fig. 2-with a shackle moving
out of the case vertically, but this is old, the only originality being that of the
employment of a bolt-K-turning upon a stump-L-in the lock case, and being
actuated by a double-veined spring-M-one vein pressing against a stump-N-
upon the surface of the bolt, and the other against the end of the shackle wherein
the bolt enters and thereby retains it in a locked position. The bolt is actuated by a
key turning upon a stump O and pressing against the part of bolt marked P either
to the Right or Left.
I also claim the raising of the bodies or cases Q and the caps or covers R of these
locks each out of one and the same piece of all kinds of sheet metal as shewn in
Bention Fia 2

page_text: 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 construction of pad locks with loose staple in lieu of the ordinary shackle
substantially as herein described and illustrated by the accompanying drawing
Fig. 1.
2-The construction of pad locks with simple locking device substantially as
herein described and illustrated by the accompanying drawing Fig. 2.
3 The raising of the bodies or cases and the caps or covers of these locks sub-
