hereby declare the-nature of this invention to be as follows:-
My invention relates to improvements in padlocks, and consists in constructing the
said locks so that the usual bow is dispensed with, the staple to which the lock is
secured entering the body of the lock and the bolt of the said lock passing through
the said staple.
In the back-plate of the padlock I form a slot or aperture adapted to receive
the staple to which the lock is to be secured. When the said lock is fitted upon
the said staple the latter enters the body of the lock and the bolt of the lock is
so formed and arranged as to enter the said staple when the padlock is locked,
thus securely retaining the lock upon the staple.
My improved padlock may be secured to one end of a short strong chain, the
other end of which is attached to the object to be secured. The said chain takes
the place and serves the purpose of the ordinary hasp and also forms a means of
attachment for the padlock, so that when unlocked and removed from the staple
it can hang by the said chain from the door, gate or other object. Or my improved
padlock may be used with the ordinary hasp fitting over the staple.
The advantages of my improved padlock are that it fits close to the object to which
it is secured, and is thus less exposed to the weather, and it is more readily secured or
unlocked than ordinary padlocks. It can be made of any suitable size or shape.

page_text: I ALLAN HUGH BREMNER of Thurso, in the county of Caithness, Ironmonger 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, reference being had to the accompanying drawing forming a part of this
specification
My invention relates to improvements in padlocks, and consists in constructing the
said locks so that the usual bow is dispensed with, the staple to which the lock is
secured entering the body of the lock and the bolt of the said lock passing through the
said staple.
In the back-plate of the padlock I form a slot or aperture adapted to receive the bow
of the staple to which the lock is to be secured. When the said lock is fitted upon
the said staple, the bow of the latter enters the body of the lock and the bolt of the
lock is so formed and arranged as to enter the bow of the said staple when the padlock
is locked, thus securely retaining the lock upon the staple.
My improved padlock may be secured to one end of a short strong chain, the other
end of which is attached to the object to be secured. The said chain takes the place
and serves the purpose of the ordinary hasp and also forms a means of attachment for the
padlock, so that when unlocked and removed from the staple it can hang by the said
chain from the door, gate or other object. Or my improved padlock may be used
with the ordinary hasp fitting over the staple.
Figure 1 is a perspective front view of my improved padlock.
Figure 2 is a perspective back view of the same, provided with a chain.
Figure 3 is a view of the inner side of the back plate, with the bolt, tumbler and
spring.
Like letters indicate like parts in all the figures.
A is the front plate of my improved padlock and B is the back plate thereof. The
usual bow by which a padlock is secured on the staple is dispensed with and the rim
or edge C of the padlock is closed all round. In the back plate B of the lock, in any
suitable and convenient position, I form a slot D of sufficient size to admit the bow E
of the staple on which the lock is to be secured, as shown in figure 3.
Around the
edge of the said slot on the inner side of the back plate B is a rim or flange D'
extending to the front plate A, the said rim or flange having a slot in its side for the
passage of the bolt. The bolt F is so formed and arranged that, when shot, it passes
through the before-mentioned slot in the flange D' and extends transversely across the
slot Dat about the centre of the said slot.
The lock is secured upon the staple by placing it thereon so that the bow E of the
said staple enters through the slot D into the body of the lock, the bolt F is then shot

page_text: and passing through the slot in the flange D¹ enters the bow E of the staple as shown
in figure 3 thus securing the said lock upon the said staple.
My improved padlock may be used with the ordinary basp fitting over the staple, or
it may be secured to one end of a short chain G (a portion of which is shown in
figure 2) the other end of the said chain being attached to the object to be secured.
The said chain serves the purpose of a hasp and also forms a means whereby the
padlock may be suspended from the door, gate or other object when not in use.
The advantages of my improved padlock are, that it fits close to the object to which
it is secured and is thus less exposed to the weather, and the rim or edge being
entirely closed also prevents the entrance of rain or dirt. It is also more readily
secured upon or removed from the staple than ordinary padlocks. It can be made of
any suitable size or shape.
I do not limit myself to the precise details and arrangement herein described and
shown, but
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 :-
A padlock having a slot D in its back-plate to admit the bow of the staple into
the interior of the lock and having a bolt which enters the bow of the said staple when
the padlock is placed thereon and locked, substantially as herein set forth and illus-
trated in the accompanying drawing.
ALLAN HUGH BREMNER.
