Improvements in Looks and Latches.
1, GEORGE WAKEMAN of Primrose Villa Hay Mills in the Parish of Yardley
Worcestershire Hardware Traveller do hereby declare the nature of this invention
to be as follows:-
A new and improved latch of the kind known by the appellation thumb latch and
of any and all forms and patterns of the same by which a latch may be lifted by
pressing a jointed or hinged lever over the handle of the same.
For the purposes of this invention I fix a lock on or in the handle-plate above
the hinged lever or "thumb-bit" and so arranged that on the application of the key
the lock-bolt slides across the said hinged lever or thumb-bit thus locking it and so
prevents the lifting of the latch in the usual way.
Dated 11th day of April 1894.
I GEORGE WAKEMAN of Primrose Villa, Coventry Road, Hay Mills in the
Parish of Yardley in the County of Worcester Commercial Traveller and
Hardware Agent 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 a new and improved method and arrangement for
locking and bolting or otherwise securing doors by the use of a latch known as a
thunib latch or of any other lift-up latches. I prefer to take for my example and
to illustrate my invention the style of latch known in trade as Suffolk or Norfolk.
To effect my purpose I fix a specially prepared lock on to the face or handle-plate
of the latch (Fig. 1), or in the absence of such plate insert a similarly constructed
lock into the door or gate to which a lift-up fatch is affixed, in such a position
that by locking the same the thumb-bit or. lifter (a) or the spindle as may be
becomes fixed and will not operate to lift the latch.
In order to accomplish this I so arrange my lock (Fig. 2) and give such shape
to the bolt (6) in the same that when locked the said bolt passes directly across
and bears upon the thumb-bit lifter or spindle (a) and holds the same so that it
will not operate on the latch to lift it.
In order to secure the latch on the inside of the door I adopt the method as
illustrated in Fig. 3 which shows the thumb-bit or lifter (a) in position and placed
through a hole vertically formed in the latch so that when the said thumb-bit or
lifter is secured by locking on the other side of the door the latch cannot be
lifted from the inside nor from outside until released by the operation of the key.
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. The peculiar arrangement and application of the lock as described and

page_text: illustrated in Figs. 1 and 2 which secures the thumb-bit lifter or spindle from
being operated upon when locked so that the latch inside cannot be raised or lifted
in the ordinary way, also-
2. The arrangement shown in the latch (Fig. 3) and the vertical or other shaped
hole therein for the purpose of passing the hooked end of the thumb-bit or lifter
or spindle (a) through, and which secures the latch inside from being lifted when
the same is locked as described on the other side.
Dated this 10th day of January 1895.
GEORGE WAKEMAN.
