of these stumps, which we will call the side stump, is at some little distance from one
side of the key hole and the other stump, which we will call the upper stump, is
arranged above the same. Upon the side stump we provide a spring which consists of
a metal strip bent so as to forin an eye to fit on to the side stump and two arms one of
which takes against the upper stump and the other and longer arm extends across to
the other side of the key hole and rests upon a projection formed on the bolt. The
said longer arm is indented or otherwise formed with a projection on its lower side and
near its outer end so as to take against the said projection on the bolt.
When the key is inserted in the lock and turned the key lifts the longer arm of the
spring and also moves the bolt forward and then the spring moves down and rests
upon and engages with the said projection of the bolt and maintains the bolt in its
shot forward position. Similarly when the key is turned in the opposite direction to
unlock the lock, the key first lifts the longer arm of the spring high enough for the
projection on the bolt to pass under it and then draws back the bolt so that the longer
arm of the spring when it resumes its normal position will engage with the projection
on the bolt and retain the bolt unlocked. The shackle is by preference one of that
kind which is made with a cross slot for the end of the bolt to engage with and the
bolt has a lump formed on it for this purpose which lump is of the full width of the
shackle; and in the lock case there is fixed a stump which forms a stop for the end of
the shackle so as to bring the cross slot of the shackle into its exact position for
the end of the bolt to shoot into it.
Our invention is similarly applicable to those padlocks in which the end of the
shackle is pierced with a hole for the bolt to shoot through, but in this case the lock
will not be so strong as that above described as the width of the fore end of the bolt
has to be reduced so as to enter the hole in the shackle.

We, DAVID WAINE and ISAAC WAINE, trading together as John Waine & Sons, of
Britannia Works, Willenhall, in the County of Stafford, Lock Manufacturers, and
THOMAS CARPENTER DOWD, of Wednesfield, in the County of Stafford, aforesaid, 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
1-
This invention has reference to padlocks and consists of the herein described
improved construction and arrangement of the bolt and a spring whereby the strength
of the lock is increased and the cost of manufacture diminished.
We will describe this invention by referring to the accompanying drawing on which
Fig. 1 shews a padlock constructed according to this invention one of the cheeks of
the padlock being removed so as to show the interior of the lock; Fig. 2 shews the
same padlock locked; Fig. 3 is a separate view of the bolt of the said padlock; Fig. 4
is a separate view of the spring which, as hereinafter described, maintains the bolt
in its locked or unlocked positions; and Fig. 5 shews the padlock case separately,
one of the cheeks having been removed.
The same letters of reference indicate the same or corresponding parts in all the
figures of the drawing.
In carrying out this invention the cheeks which guide the bolt in its backward and
forward movements are entirely dispensed with and instead thereof the bolt (marked A)
is guided by having two longitudinal slots a¹ a² formed in it which work on the
stumps 616 fixed to the lock case C. One of these stumps, namely 62, which we will
call the side stump, is at some little distance from the side of the key hole and the
other stump 61, which we will call the upper stump, is arranged above the key hole.
The key hole is not shewn on the drawing as it is formed in the cheek which is
removed, but the key hole is in the usual position indicated by dotted lines D the key
turning on the usual pin d'. Upon the said stump 6 we provide a spring E, shewn
separately by Fig. 4, which consists of a metal strip bent so as to form an eye e¹ to fit
on the said stump 62 and two arms e²e one of which namely e³ takes against the upper
stump and the other and longer arm e³ extends across the other side of the key
hole D and rests upon a projection a³ formed on the bolt A. The longer arm e³ is
formed with a projection et at its lower side and near its outer end so as to take
against the projection a³ on the bolt A. The shackle F by preference one of that
kind which is made with a cross slot f¹ for the end at of the bolt A to engage with,
and the bolt has a lump a' formed on it for this purpose which lump is of the full
'width of the shackle. In the lock case there is fixed a stump g which forms a stop
for the end of the shackle to come in contact with so as to bring the slot f' of the
shackle into its exact position for the end a* of the bolt A to shoot into.
The lock above described acts as follows: Assuming the parts to be in the positions
shewn by Fig. 1 and it is desired to lock the bolt, the shackle F is pressed down in
the usual way until its outer end comes in contact with the stop g; the key is then
inserted in the lock and turned and the key lifts the longer arme of the spring E
and also moves the bolt A forward, and the spring arm e³ moves down and rests upon
and engages with the projection a³ of the bolt A as shewn in Fig. 2 and thus
maintains the bolt A in its shot forward position. Similarly when the key is turned
in the opposite direction to unlock the lock, the key first lifts the longer arm e³ of the
spring high enough for the projection as of the bolt to pass under it and then draws
back the bolt so that the longer arm of the spring, when it resumes its normal
position, will engage with the projection as of the bolt A as shewn in Fig. 1 and thus
retain the bolt A unlocked.

page_text: Our invention is similarly applicable to those padlocks in which the outer end of
the shackle F is pierced with a hole for the bolt to shoot through but in this case the
lock will not be so strong as that above described as the width of the fore end a* of the
bolt A has to be reduced so as to enter the hole in the end of the shackle.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that
what we claim is :-
In a padlock the combination with the shackle F of the bolt A and spring E
constructed and arranged for joint operation in the manner substantially as herein-
before described and illustrated by the accompanying drawing.
