Improvements in Pad and other Locks.
WILLIAM HADLEY, 16, The Firs, Fallows Road, Small Heath, Birmingham,
Locksmith, 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 combination of parts to form greater security
and easy access to the internal mechanism of pad and other locks, the body or box
of the lock is made in one piece in any suitable shape or size in brass or other
metals and as three or more internal projections from its sides or rim, the lower
portion of these projections are cut or turned away to receive three or more
L shaped legs on the detachable cap or cover the rim is also recessed to allow the
cap to fit flush with it and the cap is fixed by being dropped into the recess and
nushed till the L shaped legs fit underneath the projections on the rim then
locked automatically by the action of the locking bolt or the shackle. Thus I
have a lock with a detachable cap or cover firmly secured without any visible
groove's, screw's, peg's, or rivet's.
The shackle of the padlock is jointed to the locking bolt in such a manner that
the joint is entirely hid when locked. and the internal mechanism is so arranged
that the flat or ordinary key's could be used in the manufacture.
To make my invention more clearly understood I append herewith a set of
drawings for future reference.
Fig. 1. gives a front view of a padlock in a round shape A is the detachable
cap, (which is now firmly fixed) B the shackle and C the rim of the box or body, the
dotted lines show position of keyhole if ordinary key's are used.
Fig. 2, gives an unlocked view, which is done by inserting the flat key (Fig. 7)
into the slot shown in Fig. 6 and pushing (or if the ordinary key is used turning)
it as far as it will go, this action raises one or more lever's to a position that allows
the shackle B and lock bolt G to be drawn outward's, the shackle B is thrown back-
ward's at the same time, and this action enable's the cap A to be moved to the
position shown, and it can now be taken off.
Fig. 3, gives a view of the internal mechanism the cap A having been removed.
D, D, D. are the projection's with their lower portion cut away E is a small block
of metal belonging to the box and help's to guide the bolt G and lock the
shackle B.
Fig. 4, show's the position of mechanism when locked, which is done by simply
pressing the shackle B inward's, the lever or lever's F secure's the bolt G, the
block E secure's the end of the shackle B, which in turn secure's the cap A
by being wedged between the block E and one of the shaped leg's on the cap A
(Fig. 5) H mark's the space occupied by the said shape leg.
Fig. 6 is a side view of lock showing slot for flat key (Fig. 7.)
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:
1. A detachable can or cover for pad and other lock's fastened internally in the

page_text: manner illustrated and described without any visible groove's, screw's, peg's,
or rivet's, and locked up by the locking action of the key or the automatic move-
ment of the shackle.
2. The method of jointing the shackle to the locking bolt, as described and
illustrated.
3. The combination of the internal mechanism with the flat or ordinary key's,
as described.
