1 SAMUEL PROCTOR of 12 Royal Avenue Chelsea in the County of Middlesex,
Butler, do hereby declare the nature of my said invention to be as follows:-
The object of my invention is to manufacture locks in such a manner as to render
them more secure than hitherto, and also to prevent persons looking through the
key-hole for prying purposes.
In carrying out my invention, I fit an improved form of escutcheon to the key-
hole. This escutcheon has a slot, or opening cut therein in such a manner that it hangs
vertically when the key is in the lock and covers the key-hole entirely, excepting that
part which is occupied by the key itself.
The escutcheon has a small hole formed in the lower end; a corresponding hole
being formed in the lock or the door, in such a position that when the escutcheon
hangs vertically, a pin or screw inserted therein, fixes the escutcheon in a vertical
position from which position it cannot be removed without the removal of the pin or
screw. This arrangement not only prevents persons looking through the key-hole from
the outside, but also prevents the key being pushed out of the lock for the purpose of
picking the lock.
My invention is applicable to box, mortise, and other locks.

page_text: I, SAMUEL PROCTOR, late of 12 Royal Avenue, Chelsea, but now of 65 Chester
Square, Pimlico, both in the County of Middlesex, Butler, do hereby declare the nature
of my said 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 my invention is to manufacture locks, in such a manner as to render
them more secure than hitherto, and also to prevent persons looking through the
key-hole, for prying purposes.
In carrying out my invention, I fit an improved form of escutcheon and cover to
the key-hole. The cover, forming part of the escutcheon, has a slot or opening cut
therein in such a manner that it hangs vertically when the key is in the lock, and
covers the key-hole entirely, excepting that part which is occupied by the key itself.
The cover part of the escutcheon has a small hole formed in the lower end; a corres-
ponding hole being formed in the lock or the door, in such a position that, when the
escutcheon hangs vertically, a pin or screw may be inserted therein, which fixes the
escutcheon cover in a vertical position, from which position it cannot be removed
without the removal of the pin or screw. This arrangement not only prevents persons
looking through the key-hole from the outside, but also prevents the key being pushed
out of the lock for the purpose of picking the lock.
My invention is applicable to box, mortise, and other locks.
And in order that my said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.
Fig. 1 is a view of the escutcheon and cover, with the key in the lock.
Fig. 2 is a similar view with the key removed.
Fig. 3 is a back view of the cover.
a is the escutcheon cover. b is a slot formed in the cover, whereby it is capable of
falling over the key-hole, and entirely covering that part of the opening which is not
occupied by the key; the key being shewn in section at k. When the key is removed
the second cover c falls over the slot and covers the key-hole, as shewn in Fig. 2. The
second cover c is pivotted upon a pin d rivetted to the cover. e is a hole provided to
receive a pin or screw, the insertion of which prevents the possibility of the escutcheon
cover being tampered with from the outside, and also prevents the key being pushed
out of the lock.
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. The manufacture and use of covers to lock-escutcheons, having a slot b, to

page_text: allow the cover to fall vertically over the key-hole, while the key is in the lock,
substantially as herein before described and shewn on the drawings.
2. The manufacture and use of covers to lock escutcheons, having a slot 6 and
additional cover c, substantially as and for the purposes herein before described and
shewn on the drawings.
3. The manufacture and use of lock-escutcheons having a hole e for receiving a
movable pin or screw to fix the same, substantially as herein before described and
shewn on the drawings.
4. The general construction, arrangements, and combinations of the several and
respective parts, together forming my improvements in key-hole escutcheons, substan-
tially as hereinbefore described and shewn on the drawings.
