Double and Single Doors and Flaps for Furniture, Carriages,
and other Objects.
We JOHN MARTIN of 47 Gerrard Street, Inventor, and JoHN COX MINEARD of
24 Barnsbury Grove, Bedroom Furniture Maker, both of Islington in the County
of Middlesex do hereby declare the nature of said invention for "A. KEYLESS LOCK
APPLICABLE TO DOUBLE WARDROBE DOORS AND OTHER DOUBLE AND SINGLE DOORS
AND FLAPS FOR FURNITURE, CARRIAGES AND OTHER OBJECTS to be as follows:-
33
The main object of our invention is to construct a keyless lock which when
applied to the "fixing door" of a double door wardrobe, shall securely lock the
tixing door" independently of the other or folding door. A collateral advantage
is that we do away with the ordinary top and bottom bolts, but we are aware that
that advantage has also been obtained by fasteners heretofore made, only that
such fasteners were dependent upon the closing of the folding door for their action.
We will describe this keyless lock with reference to an ordinary double door
wardrobe or cabinet. The "folding door" is provided with a usual lock and key,
while our keyless lock is applied in connection with the other or "fixing" door,
being fitted on the horizontal cross bar or shelf of the wardrobe. This lock is
provided with a latch or bolt of approximately S shape or double ended lever
shape mounted to turn on a pin or pivot. The end which when protruded enters
a housing on the striking plate fixed on the fixing door is made wedge shaped
tapering towards the outside and swings into the correspondingly shaped housing
on the striking plate somewhat from one side so that the door is then held closed.
This end of the bolt is swung out against a strong stop in the manner described
when the fixing door is closed against the wardrobe whereby the said door presses
against the other end of the bolt which end when the door is open normally
projects a short distance beyond its casing and is held in the normally slightly
protruded position by a spring. The aforesaid stop takes all the strain that may
come on the lock when the door is pulled by its handle. In order to secure
the bolt end in the housing the bolt is formed with a notch into which drops a
tumbler impelled by a spring in the moment that the wedge end enters the housing
Pin G21

page_text: A pusher, knob or other appliance on the front part of the lock box or casing
serves to push back the other end of the tumbler for the purpose of releasing it,
when it is desired to open the lock, whereupon the spring acting on the opposite
end of the S bolt causes the bolt to be withdrawn from its housing on the
striking plate. The folding door has a slight recess to receive the projecting
part of the pusher so that the folding door is independent of the fixing door and
vice versa.
As applied to a carriage door we prefer to fit the carriage door with a bow
handle or flush handle or ring just above the pusher thus preventing accidental
contact with the projecting part of the pusher and rendering it convenient to apply
the thumb to the pusher while taking hold of the bow.

We JOHN MARTIN of 47 Gerrard Street, Inventor, and JOHN COX MINEARD of

AND FLAPS FOR FURNITURE, CARRIAGES AND OTHER OBJECTS and in what manner
the same is to be performed to be particularly described and ascertained in and by
the following statement:-
21
The main object of our invention is to construct a keyless lock which when
applied to the "fixing door" of a double door wardrobe shall securely lock the
'fixing door" independently of the other or folding door. A collateral advantage
is that we do away with the ordinary top and bottom bolts, but we are aware that,
that advantage has also been obtained by fasteners heretofore made only that such
fasteners were dependent upon the closing of the folding door for their action.
We will describe this keyless lock as applied to an ordinary double door
wardrobe or cabinet with reference to the accompanying drawings of which
Figure 1 is a perspective view showing the lock fixed to the top of the horizontal
bar or stretcher rail A, the upper half of the fixing door B with part of the striking
plate being cut away so as not to hide the lock. Figure 2 is a plan of the lock
with the top plate removed showing the latch unlocked and with the fixing door
in horizontal section in the act of being closed, as indicated by the arrow.
Figure 3 is a plan with the top plate removed as before but showing the latch
locked into the fixing door which latter is shown in horizontal section.
The folding door is provided with a lock and key as usual, while our keyless
lock is applied in connection with the other or fixing door B, being fitted on the
horizontal cross bar or shelf A of the wardrobe. This lock is provided with a
latch or bolt D of approximately S shape or double ended lever shape mounted to
turn on a pin or pivot E. The end d which when protruded enters a housing e on
the striking plate f fixed on the fixing door is made wedge shaped tapering towards
the outside and swings into the correspondingly shaped housing c on the striking
plate somewhat from one side so that the door is then held closed. This end d
of the bolt D is swung out against a strong stop L on the casing in the manner
described when the fixing door B is closed against the wardrobe whereby the said
door presses the other end g of the bolt as shown in Figure 3. The projecting
end of the bolt normally projects a short distance beyond the casing h when the
door is open and is held in the normally slightly protruded position by a spring k
The aforesaid stop L takes practically all the strain that may come on the lock
when the door is pulled by its handle. In order to secure the bolt end d in the
housing e the bolt is formed with a notch at m into which drops a tumbler n
impelled by a spring o in the moment that the wedge end enters the housing e.
A pusher, knob or other appliance p on the front part of the lock box or casing h

page_text: た
is jointed to and serves to push back the other end of the tumbler n for the
purpose of releasing the bolt D when it is desired to open the lock whereupon the
spring acting on the opposite end g of the bolt causes the end d to be withdrawn
from its housing e on the striking plate f. The folding door may have a slight
recess to receive the projecting part or knob of the pusher p so that the folding
door is independent of the fixing door B or the casing may be formed as here
shown so that the pusher p does not project beyond the stretcher rail A.
As applied to a carriage door we prefer to fit the carriage door with a bow
handle or flush handle or ring just above the pusher thus preventing accidental
contact with the projecting part of the pusher and rendering it convenient to apply
the thumb to the pusher while taking hold of the bow. The lock is fixed to the
framing of the carriage and the striking plate with housing is fixed on the door,
or vice versa.
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
First. A keyless lock applied in connection with a door which lock is locked by
said door on closing coming against a bolt in the lock which bolt is moved a certain
distance and which takes into a housing on the door and is there held by a
tumbler and which lock may be unlocked by means of a suitable releasing
appliance substantially as set forth.
Second. In a keyless lock applied for securing the fixing door of a wardrobe and
independently of the closing of the folding door, the combination of an S shaped
lever D, a spring k, a tumbler n, a spring o and pusher 2 substantially as described
and shown.
