PROVISIONAL SPECIFICATION.
Improvement in Locks and Latches.
We LOFTUS BALFOUR MORETON trading as John Moreton & Company
Horseley Fields Wolverhampton in the County of Stafford Merchant and
JOHN STOKES of 174 Lord Street Wolverhampton aforesaid Merchants Clerk
do hereby declare the nature of this invention to be as follows:-
This invention relates to lock & latches for the purpose of adapting them so
that they may be fixed alternatively in different positions as required such as either
right or left hand.
The invention consists in having 2 keyholes in lock plates in such positions as
will suit the alternative positions for which it may be desired to fix lock.
The lock mechanism is of a kind which permits key to be inserted in either
keyhole & still lock out bolt & unlock it in direction of correct hand of lock or
edge of door. This is effected by means of two tumblers or levers which act on
each other. They also prevent throwing bolt of lock back by force as bolt is held
fast on both sides in place of one side in usual locks.

COMPLETE SPECIFICATION.
Improvement in Locks and Latches.
We LOFTUS BALFOUR MORETON trading as John Moreton & Company of
Horseley Fields Wolverhampton in the County of Stafford Merchant and
JOHN STOKES of 174 Lord Street Wolverhampton aforesaid Merchants Clerk
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 more especially to door locks, rim, mortise, dead, and
drawback, also latches for doors, enabling them to be fixed alternately, in different
positions, as required, such as either left, or right hand.
The invention consists of a mode of construction and arrangement of the internal
mechanism, whereby the key can be inserted in the usual way, right side up, and
the bolts of the lock operated, whether the lock is facing to the right or left hand
of the door on which it is fixed.
This is effected by means of a double keyhole and an interlocking cranked lever
and tumbler, connected by a pivot joint, or tongue and groove action, and other
minor arrangements hereinafter described.
I will now describe the invention with reference to the accompanying drawings
in which,
Fig. 1 shows one form of my improved lock in which a double keyhole or a
keyhole with a double pin-hole is employed, and the key operates on the inside of
the locking bolt.
Fig. 2 shows another form of same, with two separate keyholes, the key operating
on the outside of the locking bolt.
a, a, are the interlocking lever and tumbler.
b, is the tongue and groove joint. Instead of this a pivot joint can be used
if preferred..

page_text: JJ, are the two separate keyholes.
9, 9, are the notches in the bolt where the key operates.
h, is the double keyhole.
i, i, are the two projecting studs or stumps, on the bolt
the tumblers a, a.
e,
which engage with
j, is the bridge-ward of the lock. This can be omitted and a step or collar ward
used if preferred.
k, k, are two slots formed in the tail of the bolt.
The mode of action is as follows.
When the key is inserted in the lock shewn in Fig. 1, and turned round, it
first strikes against and lifts one of the tumblers a, and thereby disengages it
from the stump i. At-the same noment by means of the joint b, the opposite
tumbler a,
is also disengaged from its corresponding stump and the bolt e, is
thereby made free to be thrust forward or backward by the key.
In the lock shewn in Fig. 2 the action is precisely similar except that the key
operates on the outside of the tumbler and on notches cut on the outside of the
bolt, instead of the inside.
A latch bolt of the ordinary reversable pattern with the usual handles or knobs
can be added, or one of the patent bull nose latch bolts which requires no spindle
or handles to operate it, as described in the Specification of Loftus B. Moreton's
and John Stokes No. 22165 of 1892.
Springs such as c, and d, are employed to keep the tumblers a, in position
and cause them to engage with the stumps i.
It will be seen that the bolt e is provided with a double slotted tail k instead
of a single slot as is usual. The bolt e, is also furnished with two engaging
studs i, i, instead of one as is customary. This duplication of working parts
lessens the liability to get out of order and ensures great steadiness of action.
Instead of the stumps as shewn on the bolt, stumps may be fixed on the tumblers
if preferred and recesses be formed in the bolt to receive them.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. In a double handed lock or latch the interlocking tumblers or lever and
tumbler action b, b, or its equivalent, as herein described and set forth.
2. In a double handed lock or latch the use of double guide slots and pins
on the locking bolt, also of double stumps engaging with double followers, or
their equivalents as herein described and set forth.
3. In a double-handed lock or latch the two separate keyholes shewn in Fig. 2
allowing the key to act on the outside of the interlocking tumblers and locking
bolt, and with or without the said interlocking tumblers a, and horse shoe spring c,
as herein described and set forth.
4. In a double handed lock or latch the combination of the locking arrangements
stated in Claims 1, 2 and 3, together with a latch-bolt of the ordinary kind or
with the special bull-nose latch-bolt and staple previously patented by Loftus B.
Moreton and John Stokes the Specification of which is No. 22165 of 1892, as
herein described and set forth.
