Complete Specification Left, 16th June, 1890-Accepted, 2nd Aug, 1890
PROVISIONAL SPECIFICATION.
Improvements in Locks for Doors and other Articles.
We, JOHN MILLS, and LAWRENCE EDMUND GREEN, trading together as Mills and
Green, of Saint Anns Road, Willenhall, Staffordshire, Lock and Key Manufacturers,
do hereby declare the nature of this invention to be as follows:
The object of this invention is to so construct a lock that it will answer the double
purpose of a padlock and a hasp thus forming what we call a Hasp-Padlock" and
dispensing with the necessity of a separate hasp as is required with padlocks constructed
in the ordinary way.
In carrying out this invention the lock casing may be of any convenient form but
preferably of somewhat of a flat elongated shape having an eye at one end for securing
it to a staple or screw eye in the same way that a hasp would be secured; or this end
of the lock casing may be provided with a hinged plate or be otherwise formed similarly
to the end of an ordinary hasp. The other or free end of the hasp-padlock is formed
so as to engage with a staple which may be done by providing a slot or hole in the
hasp-padlock with which the staple will engage.
A bolt and suitable mechanism for
operating the bolt and for retaining it in its locked or unlocked positions are provided
inside the basp-padlock to be actuated by a key so that the bolt can be projected across
the said slot or opening so as to pass through the staple and lock the hasp-padlock or
be withdrawn therefrom to unlock the same when required. The front end of the said
bolt may be inclined so that the bolt will be pressed back in pushing the hasp-padlock
on to the staple and then shoot forward again to engage with the staple thus making
the hasp-padlock self locking.
Dated this 2nd day of October 1880.

COMPLETE SPECIFICATION.
Improvements in Locks for Doors and other Articles.
We, JOHN MILLS and LAWRENCE EDMUND GREEN, trading together as Mills & Green,
of Saint Ann's Road, Willenhall, Staffordshire, Lock & Key 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:-
The object of this invention is to so construct a lock that it will answer the double
purpose of a padlock and a hasp thus forming what we call a Hasp-Padlock" and
dispensing with the necessity of a separate hasp as is required with padlocks constructed
in the ordinary way.

On the accompanying drawings Figs. 1 and 2 are general views of a "hasp-padlock
constructed according to this invention as applied to securing a door, the lock being
shewn unlocked in Fig. 1 and locked in Fig. 2; Figs. 3 and 4 are views of the said
lock with the front plate removed so as to shew the internal mechanism, the parts
being represented in their unlocked positions by Fig. 3 and in their locked positions
in Fig. 4; Fig. 5 is a sectional plan of the said lock; Figs. 6 and 7 shew a modifieri
form of the said lock for fixing and securing a door window or shutter which is in. a
line with the door post or window frame; and Fig. 8 is a further modification of
he same.
The same letters of reference indicate the same or corresponding parts in all the
Figures of the drawings.
In carrying out this invention the lock casing a may be of any convenient form

but preferably of somewhat of a flat elongated shape as shewn having either an eye
at one end (see Fig. 8) for securing it to a staple or screw eye c in the same way that
a hasp would be secured; or this end of the lock may be provided with binged
plate d (Figs. 1, 2, 5, 6 and 7) having holes for fixing screws or be otherwise formed.
similarly to the end of an ordinary hasp. The other or free end of the basp-padlock is
formed so as to engage with a staple e which is done by providing a slot or hole fin
the hasp-padlock with which the staple e will engage. A bolt g and suitable mechanism
for operating the bolt and for retaining it in its locked or unlocked positions are
provided inside the hasp-padlock casing a to be actuated by a key so that the bolt g
can be projected across the said slot or opening f so as to pass through the staple e
and lock the hasp-padlock when required or be withdrawn therefrom to unlock the
same.

In the examples illustrated the bolt g, which is free to slide to and fro in the
casing a is continuously pressed forward by the spring placed on a pin in a
recess ' in the bolt and operating between the projecting stop al on the casing a and
the part g2 of the bolt. A riba is provided at one side of the slot so as to enclose
the mechanism and through this rib the bolt g projects to engage with the staple. The
bolt is operated by an ordinary key acting upon the three armed lever i which turns
upon a fulcrum on the casing a and is situated in an open ended recess at the back
end of the bolt 9 beyond which one of its arms projects towards the keybole k.
The cross arms of the lever i act upon inwardly projecting parts g* of the bolt g.
When the key is inserted in the key hole and turned in either direction it will come
into contact with the arm see Fig. 3 and move it sideways causing one of the
arms to act upon one of the projecting parts and to withdraw the bolt, and unlock
the lock. When the key is removed the spring shoots the bolt g forward again to
its locked position. The front end of the bolt g² in this example is inclined so that
the bolt will be pressed back in pushing the hasp-padlock on to the staple and then
shoot forward again and engage with the staple thus making the hasp-padlock self-
locking or the end of the bolt may be left square as in dead locks.
It will be evident that the mechanism for operating the bolt may be modified and
arranged in various ways as in other locks without departing from the nature of our
invention and that if desired the bolt can be made with wards and secured by a tumbler
or with levers.
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 is :-
1. Constructing locks so as to serve the double purpose of a lock and a hasp sub-
stantially as herein before described and illustrated by the accompanying drawings,
that is to say, making the lock casing in the form of a hasp hinged or jointed at one
end to a fixing plate or eye and having a side opening near the outer end adapted to
engage with a staple in combination with a sliding bolt and suitable operating means
contained within the casing for the purpose and substantially as hereinbefore
described.
2. A hasp-padlock constructed in either of the several ways hereinbefore described
and illustrated by the accompanying drawings.
