page_text: We SAMUEL MILLS Junior and ARTHUR MILLS trading as Mills Brothers of
Upper Hall Lane Walsall in the County of Stafford, Pad Lock Manufacturers
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 consists in an improved method of throwing out the shackles of Pad
Locks by turning the key to the right hand in the action of unlocking.
Inasmuch as there are several modifications of our improvements we will distinguish
them by figures 1, 2, 3 and 4 and at the same time referring to the accompanying
drawings.
In Fig. 1 we fix or cast a pin-A-in the centre of the lock plate, upon which
we employ a segment-B-having two stumps or pins thereon, nearest the outer
edge of the lock plate--one on the right hand side-C-and the other-D-on the
left, the latter fitting and working in a longitudinal slot-E-in and underlying an
extended part-F-of the shackle, whilst the former-C-fits and works in a similar
slot G in the upper end of an overlying plate or bolt-H-which is gated to the
key in or about the middle of the same, and swings upon a pin-I-in the bottom of
the lock plate immediately below the key-pin--and secured in a locked position
by an ordinary tumbler or lever-K-thus as the plate or bolt-H-is thrown to the
right hand by the action of the key the longitudinal slot-G-in the upper end thereof
moves the segment-B-and this also having the left hand stump or pin in the
longitudinal slot in-the-extended part of the shackle-D-the latter is simultaneously
thrown out of the lock, the reverse action-namely that of locking obviously pro-
ducing the reverse action of the shackle.
Fig. 2, differs only from Fig. 1 by the employment of a plate or arm-
-L-in lieu

page_text: of the segment for actuating the shackle-In this we also employ a swinging
bolt-M-upon a stump or pin-N-in the bottom of the lock case and having a
pin-0-on the upper end thereof-We also fix a pin-P-upon the extended part of
the shackle-Q-and upon each of these pins across the plate or bolt we place the
abovementioned plate or arm-L-so that in giving motion to the bolt by turning the
key in the action of unlocking, precisely the same action is given to the shackle as
that before described.
It will however be seen by the dotted lines that as the bolt is moved to the right
hand in giving the above action, that the plate or arm-L-is drawn down towards
the key pin-R which is an entirely novel feature, inasmuch as it affords consider-
able additional security to the lock by acting as-what is commonly known to the
lock trade as a nose-ward-and thereby necessitating a slot in the bit of the key for
it to move-into-This may be secured by either an ordinary tumbler-S-or levers
and is intended as a chain lock, that is a chain is secured to the lower part-pro-
jecting off the lock case, which, in length may be made to suit any thing it is required
to encircle, by placing any of the links in the space between the ears and locking the
shackle through the same.
In Fig. 3 we also employ a plate or bolt-T-swinging upon a stump-U-on
the left hand side of the bottom of the lock plate immediately below and in a line with
the spoon of the shackle-V-on the upper end of this plate or bolt is a hook or
catch W which enters the spoon of the shackle and thereby secures it in a locked
position, and to the right hand of the stump or pin U-upon which it swings we form
a small semicircular slot-X-within which slot the key pin-Y-stands in the lock
plate, and on the right of the pin and a little distance from the same we employ a
short projecting stud-Z-upon the plate or bolt corresponding-with-a-slot in the
underside of the key bit and against which the side of the bit abuts, but when the
key is turned sufficiently far to release the hook or catch from the spoon of
the shackle, the slot in the same passes over the projecting stud and the key may be
taken-out of the lock..
Upon a pin-7-in the upper right hand side of the plate we employ a double-
reined spring-2-one side of which is bent to a suitable angle and presses against a
corresponding angular stud upon the plate or bolt whilst the other side presses against
the spoon of the shackle, so that when the hook or catch is released therefrom the force
of spring throws out the shackle from the lock and at the same instant throws the plate
or bolt into its former position by virtue of the two inclines on the spring and stud.
The internal construction of Fig. 4-is precisely the same as-Fig. 3-only that
we apply it to a lock having a shackle moving out of the lock case in a vertical
direction and each of them—namely-Figs. 1, 2, 3 and 4, may be automatically
locked without the use of the key by simply pressing or forcing the shackles into the
lock.
We desire it to be understood that there is nothing new in the swinging bolt
beyond its application to the various devices herein described.
Fig. 5 Q is the shackle of Fig. 2.

PRAW
The other figures 2, 3 and 4 will be sufficiently understood without further
description.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim as improvements in pad locks is-
1-The employment of an arm or plate connected with the plate or bolt and shackle

page_text: for giving motion to the latter, substantially as herein described and illustrated by―
Fig. 2 of the drawings.
2-The employment of a segment connected with the plate or bolt and shackle for
giving motion to the latter, substantially as heroin described and illustrated by-
Fig. 1 of the drawings.
3&4. The employment of a swinging hook or catch and spring for actuating the
latter and throwing out the shackles and the unlocking device-substantially as herein
described and illustrated by drawings.
