I, ANDREW CASHIN, of Shakespeare Works, 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 hereindescribed new or improved pad-lock which
is constructed and arranged as follows:-
The bolt is, as in some other pad-locks, formed in a piece with or is jointed to
the shackle and is arranged to project through the top of the lock case so that in
order to unlock the pad-lock the bolt and shackle have to be moved upwardly to
project farther from the case and in order to lock the pad-lock the bolt and shackle
have to be shot back farther within the case.
I so arrange the said pad-lock and its key that the bolt and shackle are projected
forward into their unlocked position by inserting the key in the key hole and
moving the key upwardly along a vertical slot forming a part of the key hole so
that the key acts directly upon the bolt and moves the bolt and shackle
upwardly into their unlocked position. In order to secure the bolt and shackle in
their locked position I provide within the lock case one two or more levers which
engage with a corresponding projection or projections on the bolt and is or are so
arranged that when the key (which is or may be made flat) commences to be
moved along the slot as aforesaid, the key, before moving the bolt, comes in
contact with the lever or levers and moves them into such a position or positions
that they will be free of the projection or projections on the bolt which will then
be moved upwardly by the continued action of the key as aforesaid.
The said levers are by preference arranged in pairs at each side of the key hole
and vertical slot so as to bear upon the key equally. When the bolt or shackle
have been moved upwardly as aforesaid they will remain in this position by the
lever or levers pressing against the projection or projections on the bolt; and the
key can be moved back down the slot and removed from the pad-lock.
In order to lock the pad-lock it is only necessary to press the shackle and bolt
back into the case where they will be maintained by the lever or levers engaging
with the bolt as stated above.
In order to guide the key and assist in guiding the bolt there is or may be a
vertical guide bar fixed to the back of the lock case and corresponding with the
vertical slot of the key hole. The bolt is made with a vertical slot corresponding
with this guide bar so as to be guided thereby and the key also has a central
longitudinal slot to correspond with and move along the guide bar. The guide
bar may have one or more lateral projections forming wards and corresponding
with notches in the key.
Suitable stops prevent the bolt from being moved too far either in or out of the
case.
The front plate of the pad-lock has inwardly projecting bars or stops formed at
one or both sides of the vertical slot part of the key hole, these bars or stops
forming wards and corresponding with notches in the sides of the key.

page_text: A New or Improved Padlock.
I, ANDREW CASHIN, of Shakespeare Works, 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 consists of the hereindescribed new or improved padlock which is
constructed and arranged as follows:-
The bolt is, as in some other pad-locks, formed in a piece with or is jointed
to the shackle and is arranged to project through the top of the lock case so that
in order to unlock the pad-lock the bolt and shackle have to be moved upwardly to
project farther from the case and in order to lock the pad-lock the bolt and shackle
have to be shot back farther within. the case.
I so arrange the said padlock and its key that the bolt and shackle are projected
forward into their unlocked position by inserting the key in the key hole and
moving the key upwardly along a vertical slot forming a part of the key hole so
that the key acts directly upon the bolt and moves the bolt and shackle upwardly
into their unlocked position. In order to secure the bolt and shackle in their
locked position I provide within the lock case one two or more levers which
engage with a corresponding projection or projections on the bolt and is or are so
arranged that when the key (which is or may be made flat) commences to be moved
along the slot as aforesaid, the key before moving the bolt; comes in contact with
the lever or levers and moves them into such a position or positions that they will
be free of the projection or projections on the bolt which will then be moved
upwardly by the continued action of the key as aforesaid.
When the bolt and shackle have been moved upwardly as aforesaid they will
remain in this position by the lever or levers pressing against the projection or
projections on the bolt ; and the key can be moved back down the slot and removed
from the padlock.
In order to lock the padlock it is only necessary to press the shackle and bolt
back into the case where they will be maintained by the lever or levers engaging
with the bolt as stated above.
In order to guide the key and assist in guiding the bolt there is or may be a
vertical guide bar fixed to the back of the lock case and corresponding with the
vertical slot of the key hole. The bolt is made with a vertical slot corresponding
with this guide bar and the key also has a central longitudinal slot to correspond
with and move along the guide bar which latter has or may have one or more
lateral projections forming wards and corresponding with notches in the key.
Suitable stops prevent the bolt from being moved too far either in or out of the
case.
The front plate of the padlock has inwardly projecting bars or stops formed at
one or both sides of the vertical slot part of the key hole, these bars or stops
forming wards and corresponding with notches in the sides of the key.
My invention is illustrated by the accompanying drawings on which
Fig. 1 is a general front view of a padlock constructed according to this
invention; Fig. 2 shews the key for unlocking the same;

The same letters of reference indicate the same or corresponding parts in all the
figures.
I will first describe the arrangement of my invention shewn by Figs. 1 to 9 both
inclusive in which the locking of the combined bolt and shackle is effected by one
lever. A is the lock case and B is the front plate of the same together forming
an opening a at the top in which the combined sliding bolt and shackle C fits and
can slide up and down, the said combined lever and shackle C being guided by the
case and by the stop a formed within the same. D is the key for unlocking the
padlock made of flat section metal and with wards as hereinafter described. E is
the vertical slot in the front plate B of the padlock along which the key D moves
to push the combined bolt and shackle upwardly this slot E terminating at its lower
end in a cross slot el which is in fact the key hole into which the key has to be
inserted to unlock the lock. F is the vertical guide bar fixed to the back of the
lock case and corresponding with the vertical slot el and along which the key moves
when unlocking the lock. This guide bar F may be made of various forms in cross
section with which the central slot in the key D will have to be made to correspond.
In the particular example of my invention which I am now describing the vertical
guide bar F is made of a cross shape in cross section that is to say, it has two
vertical parallel projecting side ribs corresponding with the wards d' d in the
key D and it has another projecting central rib³ corresponding with the ward d³.
G is the lever or tumbler which secures the combined bolt and shackle C in its
locked position. This lever or tumbler turns on a fulcrum pin g' fixed in the lock
case and the lever has a projection g at its upper end which, when the combined
bolt and shackle are pressed into their locked position in the lock case as shewn in
Figs. 1, 2, 3 and 3*, engages with a notch or projection c¹ formed on the combined
bolt and shackle C thus maintaining the latter in its locked position. When the
lever or tumbler G is in this position its edge g³ comes in contact or almost in
contact with the guide bar F so that the lever G will be pushed away sideways by
moving the key D when the latter is moved along the guide bar F. The spring h
tends to maintain the tumbler or lever G in its locked position shewn by Figs. 3
and 3*.
To unlock the said padlock the key D has to be inserted in the cross slot e¹ and
then moved upwardly along the slot E when the key will first come into contact
with the lever G and turn the same sideways so that its end g³ will be free of the
projection e¹ of the combined sliding bolt and shackle C. The key D will now
come in contact with the lower end c² of the combined bolt and shackle C and
raise the same upwardly to its highest position as shewn in Fig. 4 so that the
padlock will now be unlocked and the combined bolt and shackle C will be
maintained in this position by the spring lever or tumbler G pressing against the
side of the bolt C. The key can now be moved down the slot E and removed
from the padlock. In order to lock the padlock the combined bolt and shackle C
have to be pressed back into the lock case where it will be maintained by the
outer end of the lever G engaging on the shoulder or projection c³.

page_text: In order to add to the security of the lock the bridge plate I shewn separately
by Fig. 7 may be fixed in the padlock to cover the main portion of the lever G
and the lower part of the combined sliding bolt and shackle C this bridge plate
embracing the guide bar F and being parallel therewith and almost touching the
same so that wards d' d have to be made in the key D to suit the bridge I. In
the key D there are also wards de d to match the sides e2e of the slot E. The
ribs & formed on the back of the plate B project inwardly as far as the bridge
plate I and effectually prevent a pick being applied to force back the lever G and
raise the combined bolt and shackle.
In the arrangement of my invention shewn by Figs. 10, 11, 12, 13, 14, 15 and 16
the combined sliding bolt and shackle C is maintained locked by several levers in
this case four in number and marked respectively G¹ G G³ G. The edges of
these levers are made of various shapes so that the wards de d d d in the key B
(Fig. 16) will all have to be made to correspond therewith and be of such a
depth that when the key D is inserted and moved upwardly along the slot E to
unlock the lock the wards d d do d" will bring the levers G G G G exactly
to such a position that they will release the combined bolt and shackle C. These
levers may be made to engage directly with the sliding bolt and shackle C as in
the arrangement shewn by Figs. 1, 2, 3 and 4, or, as shewn by Figs. 10 and 11, I
may employ an intermediate two armed lever marked J J2 which turns upon a
fulerum. One arm J' of this lever is made hooked at its upper end so as to engage
with the notches g of the levers G G G G when the latter are in their unlocked
position shewn by Fig. 11. The other arm J of the said additional lever is made
so as to engage on the projection c¹ of the bolt C and unlock the same when the
latter is in its unlocked position shewn by Fig. 10. It will be seen that when the
lock is thus locked the end of the arm J' catches on to the upper edges g³ of
the levers G G G G and thus the arm J¹ cannot be moved aside by the
projection e' of the bolt and thus the latter is locked, but when the key is inserted
and has moved the levers G G G G sideways to their proper positions the end
of the arm J will drop into the notches y' of the said levers and then the arm Ja
will be free of the projection el and the bolt can be shot up unlocked. A spiral
spring such as K (Figs. 10 and 11) may be employed in the lock case to cause the
combined bolt and shackle C to shoot upwardly to its unlocked position when the
key has been inserted and has pushed back the lever or levers to release the combined
bolt and shackle C as stated above. As before stated the shackle part of either be
made solid with the bolt part as in Figs. 1, 3 3 and 4 or as shewn in Figs. 10
and 11 the shackle et may be hinged as at to the sliding part so as to throw
open when the padlock is unlocked.
It will be evident that without departing from the nature of my invention any
number of levers may be used to engage with the combined sliding bolt and
shackle C and retain the same in its locked position, and that instead of the lever
or levers being arranged on only one side of the key hole similar levers or tumblers
may be arranged at both sides of the same.
The side projection c on the lower end of the combined bolt and shackle C comes
into contact with the stop a when the lock is unlocked and thus prevents the bolt
and shackle from being shot forward too far.
Having now particularly described and ascertained the nature of my said inven
tion and in what manner the same is to be performed, 1 declare that what I
claim is
1. In a padlock and in combination with the case, the combined bolt and shackle
projecting from the top of the case and adapted to slide to and fro therein, one or
nure spring levers within the case adapted to engage with the said sliding bolt
when the latter is pushed back into its locked position within the case, a combined
cross and vertical slot or key hole in the padlock front for the insertion and
movement of the key, a guide bar for the key fixed to the back of the case parallel
with said slot, these parts being so arranged that when the key is inserted in the

page_text: cross slot and moved along the vertical slot and guide bar the key forces back the
lever or levers and carries up the combined bolt and shackle, and when the latter
are pushed back into the locked position the lever or levers engage therewith, all
substantially as hereinbefore set forth.
2. In a padlock of the kind denoted under Claim 1 making the guide bar F with
a parallel side or other rib or with parallel side or other ribs and making the key
with a ward or wards to correspond therewith, substantially as described.
3. In a padlock and in combination with the case, the combined bolt and
shackle C the spring lever G, adapted to engage with the sliding bolt when
the latter is pushed back into its locked position within the case, the combined
cross and vertical slot E el in the padlock front for the insertion and movement
of the key, the guide bar F for the key fixed to the back of the case parallel
with the said slot these parts being constructed and arranged and the combined
bolt and shackle and spring lever operated by inserting the key in the cross slot e
and moving the same along the vertical slot E, all substantially as hereinbefore
described and illustrated by Figs. 1 to 9 of the accompanying drawings, the
said padlock being either made with or without the bridge plate I for the purpose
set forth.
4. A padlock constructed arranged and operated substantially as herein before
described and illustrated by Figs. 1 to 9 of the accompanying drawings.
5. A padlock constructed arranged and operated substantially as hereinbefore
described and illustrated by Figs. 10 to 16 of the accompanying drawings,
whether the upper part e, of the combined bolt and shackle is made hinged as
in these figures or made solid with the slide as in Figs. 1, 3, 3 and 4 of the
accompanying drawings.
