PROVISIONAL SPECIFICATION.
Improvements in or applicable to Locks.
I CHARLES TAYLOR of 16 Regent Street Eccles in the County of Lancaster,
Plumber and Gasfitter, do hereby declare the nature of this invention to be as
follows:-
This invention is designed to enable a key to be inserted into a lock without
any difficulty from the outside of the door, or other place where it may be fixe:
so that however worn the aperture through the wood of the door drawer or other
article may have become or however large it may have been originally made, the
key can without trouble be at once inserted into the hole in the lock rase.
For this purpose on the outside of the keyhole in the inuer side of the lock,
that is, the side let in or otherwise applied to the door, I fix or form a
projecting socket fitting around the eye and part of the slot of the said key
hole and slightly larger in size and on the inside of the scutcheon I fix or
form a similar socket corresponding in size and shape with the eye and part
of the slot of the keyhole so that it will fit into the said socket on the
lock case.
Thus when the key is inserted through the scutcheon it finds its way immediately
into the lock being guided by the socket which forms a channel or slide direct to
the said lock.
It will be evident that by making a socket of sufficient length on the lock case
the socket on the scutcheon can slide telescopically therein and the key guide can
thus be adjusted to suit different thicknesses of doors or other articles for which
the lock may be required.
The socket or channel may if preferred be made separate from the scutcheon so
that it can be applied to existing locks, by simply fixing a socket as first above
described on the inner side of the lock case.

COMPLETE SPECIFICATION.
Improvements in or applicable to Locks.
I CHARLES TAYLOR of 16 Regent Street Eccles in the County of Lancaster,
Plumber and Gasfitter, 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 is applicable to that class of door locks known as "rim-locks'
and the invention is designed to enable the key to be inserted into a lock without
any difficulty from the outside of the door or other place where it may be fitted,
50 that however worn the aperture through the wood of the door, drawer,
box, or other article may have become, or however large it may have been
originally made, the key can without trouble be at once inserted into the hole in
the lock case.
The invention also makes provision for the accurate adaptation of the lock to
different thicknesses of timber.
Figure 1 on the drawings annexed hereunto is an elevation of a rim-lock with
my invention (drawn in section) shown as applied thereto and Fig. 14 is a face view
of the escutcheon.

page_text: Fig. 2 is a similar view of a rim-lock with my invention applied thereto as
adapted for thicker doors than that shown at Fig. 1.
Fig. 2 is a face view of the escutcheon and Fig. 2B is a plan view of my
improvement.
In these views the thickness of the door is represented by the dotted lines,
a is the casing of the lock, is the handle and c is the escutcheon plate.
On the outside of the ordinary casing a of the lock that is, upon the side that is
let in or otherwise applied to the timber I fix or form a projecting socket d
embracing the keyhole of the lock but slightly larger in size.
By the terin embracing I mean either fitting entirely around the keyhole or
fitting around the eye and part of the slot of the keyhole. On the inside of the
escutcheon plate c I fix (or cast with it) a similar socket piece or guide e similar in
size and shape inside to the eye or keyhole in the lock case a and fitted to slide
telescopically inside the fixed socket of as shown at Fig. 1. Thus when, the key is
inserted through the escutcheon e it passes directly into the key of the lock being
guided by the socket piece or channel e. This guide or channel is made in two
pieces one sliding telescopically within the other in order that it may be fitted to
timber of varying thicknesses within a certain range.
When the invention is intended to be applied to thicker doors I use an inter-
mediate slide or channel ex as shown at Figs. 2, 24, and 2B, in which case I prefer
to make the fixed socket d with a slot. dx and to provide the intermediate slide ex
with a pin e' sliding therein (see Fig. 2B) so that the latter remain attached to the
socket d.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The combination with a rim lock of a fixed socket or guide embracing the
keyhole with a telescopic guide or guides sliding therein and attached to the
escutcheon plate substantially in the manner and for the purpose herembefore set
forth.
