IMPROVEMENTS IN OR CONNECTED WITH DOORS AND DOOR FASTENINGS
Year: 1885

page_text: I GEORGE BEADON of Creechbarrow near Taunton in the County of Somerset,
Captain in the Royal Navy do hereby declare the nature of the said invention for
IMPROVEMENTS IN OR CONNECTED WITH DOORS AND DOOR FASTENINGS to be as
follows:-
The invention has for its object improvements in or connected with doors and
door fastenings, and consists in connecting the moveable batten which is sometimes
placed below the bottom rail of a door with the lock gear so that by turning the
door handle the fastening bolt is withdrawn from the striking plate and the
moveable batten simultaneously raised from the floor, before the door is moved on
its hinges and when the door is open the moveable batten is kept elevated from
the floor and the bolt kept withdrawn within the lock frame until the door is
closed, when the fastening bolt is again moved into its socket in the striking plate
and the moveable batten closed on the floor by gravity thereby obviating the use
of springs or rising binges.
I would observe that the idea of a tongued batten working in suitable guides
and grooves in the bottom rail of a door is not new, a working model having been
placed by me in the great exhibition of the year 1851 but it had springs which
I now find are not required.
In carrying my invention into effect various constructions of parts may be
employed as it is equally applicable to mortise locks, rim locks and latches.
The spindle of the lock may be caused to operate the fastening bolt by means
of a toothed wheel or segment on the spindle working in a toothed rack formed on
the bolt, or a slotted or forked lever on the spindle may act on a pin fixed in the
bolt, or the spindle may have an eccentric fixed thereon which works in a strap
fixed to the bolt or other suitable operating means may be employed.
The moveable batten may be connected by a cord, chain or wire passing over
a suitable guide pulley to an arın or lever or pulley fixed on the lock spindle or to
a sliding bar or rack operated by a toothed wheel fixed on the spindle or other
suitable means of connection may be employed, such for example as a lever
mounted on a centre of motion carried by the door, one end being acted upon
by an eccentric on the lock spindle and the other end being connected to the
suspending gear of the moveable batten.

page_text: A stop bolt when the door is open acts to lock back the fastening bolt and keep
it withdrawn within the lock case but when the door is closed such stop bolt is
acted upon by the door frame or by an incline or other suitable device fixed thereto
so as to withdraw such stop bolt from the fastening bolt when the moveable batten
will fall by gravity and by means of its connections with the lock spindle will
partially rotate the same and thereby shoot the fastening bolt. Or an eccentric
upon the lock spindle when the door handle is turned in one direction may be
caused to operate the stop bolt or to act directly upon the fastening bolt or some
part carried thereby in order to retain the fastening bolt in its withdrawn position
in which case it will be necessary to rotate the door handle in the reverse direction
in order to release it,

I GEORGE BEADON of Creechbarrow, near Taunton, in the County of Somerset,
Captain in the Royal Navy 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:—
-
The invention has for its object improvements in or connected with doors and
door fastenings and consists in connecting the moveable batten which is sometimes.
placed below the bottom rail of a door, with the lock gear so that by turning the
door handle the fastening bolt is withdrawn from the striking plate, and the
moveable batten simultaneously raised from the floor, before the door is moved on
its hinges, and when the door is open, the moveable batten is kept elevated from
the floor, and the bolt kept withdrawn within the lock frame until the door is
closed, when the fastening bolt is again moved into its socket in the striking plate
and the moveable batten closed on the floor by gravity thereby obviating the use
of springs or rising hinges.
I would observe that the idea of a tongued batten working in suitable guides
and grooves in the bottom rail of a door is not new, a working model having been
placed by me in the Great Exhibition of the year 1851 but it had springs which
I now find are not required.
In carrying my invention into effect various constructions of parts may be
employed as it is equally applicable to mortise locks rim locks and latches.
The spindle of the lock may be caused to operate the fastening bolt by means
of a toothed wheel or segment on the spindle working in a toothed rack formed on
the bolt, or a slotted or forked lever on the spindle may act on a pin fixed in the
bolt, or the spindle may have an eccentric fixed thereon which works in a strap
fixed to the bolt or other suitable operating means may be employed.
The moveable batten may be connected by a cord, chain or wire passing over
a suitable guide pulley to an arm or lever or pulley fixed on the lock spindle or to
a sliding bar or rack operated by a toothed wheel fixed on the spindle or other
suitable means of connection may be employed such for example as a lever
mounted on a centre of motion carried by the door, one end being acted upon by
an eccentric on the lock spindle and the other end being connected to the
suspending gear of the moveable batten.
A stop bolt, when the door is open acts to lock back the fastening bolt and keep
it withdrawn within the lock case, but when the door is closed such stop bolt is
acted upon by the door frame or by an incline or other suitable device fixed thereto
so as to withdraw such stop bolt from the fastening bolt when the moveable batten
will fall by gravity and by means of its connections with the lock spindle will
partially rotate the same and thereby shoot the fastening bolt. Or an eccentric
upon the lock spindle when the door handle is turned in one direction may be
caused to operate the stop bolt or to act directly upon the fastening bolt or some
part carried thereby in order to retain the fastening bolt in its withdrawn position,
in which case it will be necessary to rotate the door handle in the reverse direction.
in order to release it,

page_text: In the accompanying drawings I have illustrated one method in which I carry
my invention into effect: Figure 1 represents a side elevation of a door fitted with
my improvements: Figure 2 is an edge view of the lower part thereof and
Figures 3 and 4 are views drawn to a larger scale than Figures 1 and 2,
representing the interior of the lock and the connection of the same with the
moveable batten: Figure 3 shows the parts of the lock in the position they would
assume when the moveable batten is in its raised position and Figure 4 shows the
position of the parts when the batten is lowered.
a represents the door and b the moveable batten which is fitted within a recess
formed in the bottom of the door or is mounted on suitable guides thereon. c is the
lock which in the arrangement shown in the drawings is provided with the following
details and means of connection with the moveable batten b. On the spindle c¹ of
the lock is fixed a lever d in the ends of which are formed slots d¹, d, the former d¹
of which receives a stud e¹ fixed to the bolte whilst the other d³ receives a stud f¹
fixed to the sliding bar f which latter by a chain g passing over a guide roller h
is connected to a rod i fixed to the moveable batten b. j is a catch which as
shown at Figure 3 acts to keep the bolt e in its retracted position when the door
is open and consequently to retain the moveable batten 6 in its raised position
until the door is fully closed when by the nose or projection of the catch j coming
against the striking plate k the said catch j will be pushed in and it will thereby
release the bolt e when by the weight of the moveable batten 6 the latter will fall
and close the space between the bottom of the door and the floor and it will at
the same time cause the shooting of the bolt e. I would here remark that my
invention is equally applicable to all kinds of internal and external doors and
gates and I would further remark that various arrangements of locks or other
fasteners and of means for connecting the same with the moveable batten and of
retaining the latter in its raised position whilst the door or gate continues open,
may be employed without departing from the nature of my invention so long as
the moveable batten or closing means is connected with the bolt of the lock and
acts by gravity in the manner described.
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 :-
Connecting the moveable batten or closing means with the lock or fastening gear
so that on releasing the fastening bolt or catch from the striking plate the moveable
batten or closing means is simultaneously raised from the floor or ground before
the door or gate is moved on its hinges and when the door or gate is open the
moveable batten or closing means is kept in its raised position and the bolt or
catch retained in its unlocking position until the door or gate is closed when the
bolt or catch again locks the door or gate and the moveable batten or closing
means is closed on the floor or ground by gravity substantially as herein shown
and described.
