TRUVIDIONAL DIMITIVATION.
Certain Improvements in Pad Locks.
I, GEORGE DYER WOOD of 28 Wednesfield Road Willenhall in the County of
Stafford, Lock Manufacturer do hereby declare the nature of this invention to be
as follows:-
-:
This invention consists of the herein described improvements adaptable to all
kinds of pad locks.
The inner roundabout that forms the top of a pad lock, when it is hanging, is
made to form a circle, with a piece cut or left out of the top, sufficiently large to
allow a staple or other article to be loosed into the middle. The shackle and bolt
are made in one piece, (and are afterwards referred to as the shackle-bolt) and
when the lock is open the extreme end only of it can be seen as it has been drawn
into the lock by the key. The shackle-bolt is made to fit the roundabout, and
move round it when propelled by the key, or slots may be made in it for it to slide
along pegs, and pieces will be left out of the shackle-bolt to correspond with the
part that is open of the roundabout. The lower or inner part of the shackle-bolt
will be broader and flatter than at the ends (which will be either round or square)
and in this flat part notches will be made in such positions that when the key is
turned it will fit in these notches and pull the shackle-bolt round and close up the
opening at the top of the roundabout, which then with the shackle-bolt will form a
complete circle. To hold the shackle-bolt in position, whether locked in or out,
levers are put in the lock, which will work on the flat part of the shackle-bolt and
as the key moves the shackle-bolt round it will also lift up the levers and leave
room for a peg (that stands of the face of the shackle-bolt) to move with the
shackle-bolt, and the levers when freed from the key, will be pressed into position
again by a spring, and a slit or notch will be made in the levers to receive the peg,
which will hold the shackle-bolt in position.
This improved lock can be worked with a key that has either a single or double
bit, or be made to lock once, twice or thrice and with as many levers as may be
required to give it great security.

Certain Improvements in Pad Locks.
1, GEORGE DYER WOOD of 28 Wednesfield Road Willenhall in the County of
Stafford, 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 :-
This invention has for its object the forming and arranging of the various parts
of the mechanism of all kinds of pad locks so that there shall be, the least possible
chance of any of the working parts getting out of order. The inner roundabout
that forms the top of a pad lock, when it is hanging by the shackle, is made to
form a circle with a piece cut or left out of the top sufficiently large to allow a
staple or other article to be loosed into the middle. The shackle and bolt are
made in one piece and are afterwards refered to as the "shackle-bolt" and when
the lock is open the extreme ends of it only can be seen as it has been drawn into
LD OUT

page_text: the lock by the key. The shackle-bolt is made to fit the roundabout and move
round it when propelled by the key, or if the inner roundabout is required to be of
any other form than round slots may be made in the shackle-bolt for it to slide
along pegs and pieces will be left out of the shackle-bolt to correspond with the
part that is open of the roundabout. The lower or inner part of the shackle-bolt
is broader & flatter than at the ends, (which may be either round or square) and in
this flat part notches are made in such positions that when the key is turned it will
fit in these notches and pull the shackle-bolt round & close up the opening at the
top of the roundabout, which then with the shackle-bolt will form a complete
circle. To hold the shackle-bolt in position whether locked in or out levers are
put in the lock which will work on the flat part of the shackle bolt and as the key
moves the shackle bolt round it will also lift up the levers and leave room for a
peg (that stands off the face of the shackle-bolt) to move with the shackle-bolt and
the levers when freed from the key will be pressed into position again by a spring
and a slit or notch will be made in the levers to receive the peg which will hold the
shackle-bolt in position.
In order that this invention may be more clearly understood I will proceed to
describe a practical illustration of the same and I will refer to the accompanying
sheet of drawings on which the same letters of reference indicate the same or
corresponding parts in all the figures of the drawings.
Fig. 1 is a plan view of a pad lock case with the front plate removed showing
how the case is made. A is the outer roundabout, B the inner roundabout is of
circular form with a portion of the circle cut away to allow of a staple or other
article being loosed into the middle of the same, C is a stop of the same height.as
the roundabouts, that blocks up the space between the roundabouts to prevent
anything being pushed into the lock when it is open. The peg D is rivited on the
back plate E and forms the centre on which the shackle-bolt works. F is the key
drill pin, G is the peg on which the levers work and H. H. H. are the rivets by
which the case is secured together on completion.. On Fig. 2 is shown the shackle-
bolt as it appears when it is drawn into the lock by the key, the part of the
shackle-bolt marked a is flat in section only being sufficiently thick to bear the
strain upon it. The part a¹ is square in section for strength and to fill up.
the opening between the back and front plates of the lock. As will be seen on
refering to the drawings the shackle-bolt is made to fit on the peg D a hole being
made through it for that purpose or the peg D may be secured to the shackle-
bolt and the back plate E countersunk to receive it, and when the key is turned
on the drill pin F towards the right the bit of the key will fit in a notch c, and by
turning the key still further it will lift up the lever d shown by dotted lines and
free the peg e that stands off the face of the shackle-bolt a, and as the said shackle-
bolt moves around the inner roundabout it passes out of the opening at the top of
the lock and fits itself into the opposite side as shown on Fig. 3. thus effectually
securing itself to anything that may have been placed in the hole formed by the
inner roundabout B. Immediately the shackle-bolt a & a' has reached the position
shown on Fig. 3 by means of the key, the lever d is also released by the key which
with the assistance of the feather spring g is pressed back again and secures the
peg.e as shown on Fig. 3. To open the lock again it is only necessary to turn the
key round to the left and the lock is then opened without further trouble as
the shackle-bolt a' is drawn by the key into the lock again.
a,
When it is desirable that the hole formed by the inner roundabout should be
extra large it will be necessary slightly to alter the shape of the shackle-bolt
although it is still kept in one solid piece. Fig. 4 shows how this arrangement is
carried out.
The shackle-bolt is made to fit the inner roundabout B which forms the guide to
hold the shackle-bolt in position. So that this lock may be opened by turning the
key once round in the lock, a key may be used that has a double bit and which
would be placed in the lock through the front plate as shown by Fig. 7. or an
ordinary key may be used in the usual way and then it would require that the key,

page_text: be turned round twice to throw the shackle-bolt into the position shown on Fig. 5.
The end of the shackle-bolt a Figs. 4 & 5 is made square in section so that it will
fill up the opening between the front & back plates when the shackle-bolt is drawn
into the lock as shown on Fig. 4. To hold the shackle-bolt a Figs. 4 & 5 from
moving backwards or forwards without a key, the lever J shown by the dotted
lines Fig. 4 is used, which will be lifted by the key to allow the peg e to pass round
until it reaches the position shown by Fig. 5.
Should it be necessary to make the inner roundabout B any other shape than
circular as for example the shape shown on Fig. 6 it is arranged that the shackle-
bolt a have slits made in it as N Fig. 6, and peg N 1 standing off the face of the
back plate E, which will have the effect of giving it the same circular movement
as in Figs. 4 & 5.
When required the locks can also be made to lock three times by altering the
notches c in the shackle-bolt a and levers J so as only to throw out the said
shackle-bolt the required distance. Although the whole of the illustrations on the
drawings show the shape of the lock to be oval it can be made in any desired shape
so that there is left sufficient room inside the lock for the working of the several
parts, and can be made either in cast or wrought metal. The drawings illustrate
a lock made with a shackle-bolt that moves from left to right, and by simply
reversing the several parts it will be made to move from right to left.
Having now particularly described & 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
1st. The herein before described method of constructing and arranging the shackle
and bolt in one solid piece of metal in connection with all kinds of pad locks, sub-
stantially the same as shown & described in this Specification and the drawings
accompanying the same.
2nd. The hereinbefore described method of arranging the shackle-bolt in
connection with all kinds of pad locks so that it is propelled in and out of the
case of the lock substantially the same as described in this Specification and
drawings.
3rd. An improved pad lock constructed as herein before shown.
