PROVISIONAL SPECIFICATION.
Improvements connected with Locks and Latches, also Keys and
Handles for the same.
I, ERNEST WILLIAM BEECH, of 11 The Pavement, Wanstead, Essex, Builder,
do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements connected with locks and latches, also
keys and handles for the same.
For the purpose of my invention, I indent or form the outer shell of a door
handle hollow or sunken to such a depth for the bow of a key to lodge in and be
readily turned. The handle stem or shank is hollow for the key to be passed into
it, to the lock or the latch mechanism for locking and unlocking purposes. The
lock or the latch may be of any known kind for which by slight alterations or
additions, the mechanism can be acted upon by a key from within the latch handle.
This may be easily accomplished by a lever, or levers, tumbler, or tumblers to be
lifted, pushed sideways, or downwards by the key when inserted, and left there
when the lock has to act as a latch only, the removal of the key converting the
latch into a lock until the key be again inserted.
The key is preferably of the tubular kind with ward jaws at the end to act upon
a spring or springs to push them or projections therefrom clear of the latch bolt,
other or half-wards on the stem of the key being utilized for acting on the bolt by
a turning motion.
The usual or any sliding plate can be fitted to the lock to fix the bolt as a night
catch if desired

Improvements connected with Locks and Latches, also Keys and
Handles for the same.
I, ERNEST WILLIAM BEECH, of 11 The Pavement, Wanstead, Essex, Builder,
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 relates to improvements connected with locks and latches, also
keys and handles for the same.
For the purpose of my invention, I indent or form the outer shell of a door
handle hollow or sunken to such a depth for the bow of a key to lodge in, and the
handle be readily turned.
The handle stem or shank is hollow for the key to be passed into it to the lock
or the latch mechanism for locking and unlocking purposes. The lock or the latch
may be of any known kind for which by slight alterations or additions, the
mechanism can be acted upon by a key from within the latch handle. This may
be easily accomplished by a lever or levers, tumbler or tumblers to be lifted,
pushed sideways, or downwards by the key when inserted, and left there when the
lock has to act as a latch only, the removal of the key converting the latch into a
lock and the handles fixed until the key be again inserted.
The key is preferably of the tubular kind with ward jaws at the end to act upon
Prine 8d1

page_text: a spring or springs to push them, or projections therefrom clear of the latch
bolt, other or half wards on the stem of the key being utilised for acting on
the bolt.
The usual, or any sliding plate can be fitted to the lock to fix the bolt as a night
catch if desired.
My invention will be clearly understood by reference to the annexed drawings.
Figure 1 is an internal elevation of the casing with the latch bolt in a shot
position.
:
Figure 2 a similar view with the bolt removed.
Figures 3, 4, and 5 are elevations of the fixed and the removable plate which
secures the lock to a door.
Figure 6 a sectional elevation of a complete catch lock, the key in one handle.
Figure 7 is a similar section of the lock when the catch is used as a bolt, the
key in this instance being partially withdrawn, or in the position it is usually shot
to by the internal springs when the handle lip has been depressed prior to the key
being removed.
Figure 8 shows the spring plate by which the key is held firmly in the lock when
the article has to be used as a catch lock.
Figure 9 is a detached view of the handle stem on line 1-2 of Figure 7 with
slots for wings on the key to pass into and act as guides for the wings to press
against internal pins.
Figure 10 is a part view of a handle with the lip of the spring plate exposed.
Figure 11 represents a plan view of the lock, the nose of which can be turned in
the saddle for either right or left hand side closing doors.
Figure 12 indicates my right or left hand bolt nose as for use with a barrel lock,
a quadrant being shown instead of the pin method, as at Figure 1.
It may here be mentioned that both handles of my lock are constructed for the
reception of the same key, the insertion of which into either handle converts the
bolt lock into a catch lock, the removal of the key converting the catch lock into
a bolt lock. When the lock is a catch, the key is in one of the handles, and these
can be turned for opening, but when as a bolt lock, the withdrawal of the key
prevents the handles being turned the same bolt being used as a catch, or as a
locking bolt.
A, mortice lock case or box with circular hole B in front for the nose C of
bolt D to be turned in for right or left hand motion.
The neck of the nose C is either fitted to be revolved in the saddle E, as at
Figure 1, or in a slot of the bolt head, as at Figure 12, the nose in either case
being held for travel by the outer plate F. The saddle E which constitutes the
bolt has a pair of legs each with a crutch G, G, for the studs H, H, projecting
from the edge of a plate I to act against to draw it back when either handle J is
turned, the bolt acting at this time as a catch.
Each handle has a recess with a key hole in it centrally, and at the back of the
handles internally is a spring plate K to partially close the key hole, and to yield
as the key L is being inserted and then to spring up in front of a ward M of
the key, and fix it in place, the bow of the key being in the hollow of the handle,
as shown.
The key has a number of plain yet radial projections N on it and these as the
key enters the radial slots P, Figure 9, press against projections Q on a corre-
sponding number of pins R, each of which bear against duplicate pins, and are
pressed in contact by springs S. These pins have different lengths of recesses for
engaging or missing the edges of grooved plates T, T see Figures 2, 6, and 7, these
being fixed to the lock casing A.
When the key is inserted in either handle, the pins R are pushed in to bring
their recesses to coincide with the fixed plate T to allow either of the handles
being turned in either direction to open the door to which the lock is fitted, and
when the key L is to be withdrawn, the lip U of the plate K is pressed inwards, as
at Figure 7, to free the key from the plate K, this being effected by the rebound of

page_text: the springs S which resume their normal positions and force the projections of the
pins R into the grooves of the fixed plate T, so as to lock the bolt by preventing
the handles being operated. A fresh insertion of the key in either handle shifts
the position of the pins R, and permits of the handles turning when rotated, the lock
being then as a catch only.
At Figure 1, I show a stop stud V which when the key is removed and the
handles fixed, the bolt cannot be forcibly pushed back.
In place of the stud pins H I may provide the internal socket W with a
quadrant X to draw back the bolt, said socket being in substitution for the
plate I.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In a combined catch and bolt lock, the arrangement of the several parts, as
shown, and their method of operation, as before described.
2. In a combined catch and bolt lock, duplicating the pins R, R, plates T, T,
springs S, S, handles J, J, for the bolt to act as a catch when the key is inserted in
either handle, and as a bolt when the key is withdrawn, the internal parts for
locking purposes, then acting to fix the handles, as set forth.
3. In a positive lock, or in a catch lock, the arrangement of appliances in the
handles, in combination with the fixed plate or plates to lock or release the bandle
or handles by the means and for the purposes described.
