I, GEORGE LOCKLEY, of No. 7, King Street, Willenhall, in the County of Stafford,
Lock Manufacturer, do hereby declare the nature of this invention to be as
follows:-
By the arrangement of a slide working on the outside of the back of the lock
case connected with pins & spring to the bolt that is inside the lock, the said
bolt is prevented from being drawn from the shackle unless the said slide is first
moved out of the position in which it is held by the spring.
To receive the pin end of the key when it is inserted into the lock, a centre bit
is cast or otherwise in one piece with the lock case thus forming a centre for the
key to work on and round the said centre bit to help to keep the key from moving
a wheel is cast or otherwise thus adding greater security to the lock when com-
pleted.

I, GEORGE LOCKLEY, of No. 7, King Street, 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:-
By the arrangement of a slide working from the outside of the back plate of a
pad lock and connected with pin and spring to the lock bolt that works inside the
lock case by means of an oblong hole in the said back plate, the said lock bolt
is prevented from being moved to free the shackle, unless the said pin that is
attached to the slide is moved into a desired position from the position in which it
is held by suitable spring.
To receive the pin end of the key when it is inserted into the lock, a centre bit
is cast or otherwise formed in one piece with the back plate in the shape of a cone
thus forming a centre for the key (which is drilled to fit the said centre bit) to
work on and as a further security to keep the key in position a wheel is cast or
otherwise fixed on the said back plate round the said centre bit thus also forming
greater security to the lock when completed for use.
I will now proceed to describe this my invention in conjunction with the accom-
panying sheet of drawings. The same letters of reference occuring on different
figures indicating corresponding parts,

page_text: To keep the illustrations as clear as possible as far as these my inventions are
concerned I have omitted all tumblers, levers, curtains, springs and such like
working parts from the drawings that are not included in or effected by the inven-
tions although such omitted working parts will be required in the construction of
the lock.
Fig. 1, is the outside view of an ordinary pad lock back plate showing the
oblong hole A which is dovetailed as shown on Fig. 4, so that the pin B Fig. 2
may not be pulled through the hole A when moved in position by the slide C Fig. 3,
to which it is attached as shown by Fig. 8 which is a vertical section through
the centre of the back plate Fig. 1, having the arrangement shown thereon of the
position that the pin B is kept in by means of the spiral spring D.
Fig. 5, is the inside view of the lock showing the position of the lock bolt E,
spring bolt F, shackle G, and pin B, when the shackle G, is secured and locked
by means of the spring bolt F.
To release the shackle G, and so open the lock the key H, Fig. 9, would be
inserted into the lock to fit on the centre bit J, turning the key to the right and
throwing the lock bolt E, to position shown in Fig. 6. It will be noticed on
Fig. 6, that the pin B, is now in a position in the lock bolt hole K, that will
prevent the lock bolt F, from being moved again by the key unless it is raised
up by means of the slide C, to a position immediately opposite the left hand part
of the lock bolt hole K. When the pin 13, is so raised and the key, again turned
to the right the lock bolt E, which is now touching the spring bolt F, will draw
the spring bolt F out of the shackle G, into the position shown on Fig. 7, where
it will be observed that the pin B, is now on the extreme left of the lock bolt
hole K.
The spring bolt F, may if desired have a spring attached to the back to force
it back again into the position shown on Fig. 6, in which case the shackle G,
would have to be slightly pushed to secure it again as on Fig. 6, when by turning
the key H, once to the left it would throw all the working parts into the position
shown on Fig. 5.
To further secure the key H, in position when inserted into the lock on the
centre bit J, a wheel L, is formed round the said centre bit J, standing off the
inside face of the back plate as shown on section Fig. 8, and to fit on this a slit M,
Fig. 9, must be made in the key to fit same.
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:
-
.
1st. A pad lock having a slide on the outside of the back plate connected to
the bolt inside the lock by means of a pin that is secured to the slide, which said
slide and pin prevent the key moving the bolt except when put in required
positions substantially the same as shown in this specification and the accom-
panying sheet of drawings.
2nd. A pad lock having a centre bit in the shape of a cone and a wheel round
it, with a key made to fit and work thereon substantially the same as shown and
described in this specification and the accompanying sheet of drawings.
