Year: 1878

page_text: LETTERS PATENT to Charles Henry Parkin, of New North Road, Hoxton, in
the County of Middlesex, for the Invention of "IMPROVED ARRANGEMENTS
FOR FASTENING AND SECURING DOORS OK SHUTTERS."
Sealed the 5th November 1878, and dated the 9th August 1878.
PROVISIONAL SPECIFICATION left by the said Charles Henry Parkin at
the Office of the Commissioners of Patents on the 9th August 1878.
CHARLES HENRY PARKIN, of New North Road, Hoxton, in the County of
Middlesex. "IMPROVED ARRANGEMENTS FOR FASTENING AND SECURING DOORS OR
SHUTTERS."
My Invention consists of improvements in locking or securing and unlocking
doors, shutters, and such like, whether inside or outside, where a bar is used.
In the ordinary way doors are secured by a bar, which in the case of folding
doors is fastened to one of the doors, and when the doors are brought together
such bar, which is provided with an opening, takes into a ring fixed to the other
door, through which a padlock or lock is passed, and same is secured by locking
in the ordinary way. It is evident that by these means the lock can be wrenched
off, and thus the bar is released, and entrance obtained into the premises.
Now to obviate these defects I adopt improvements mainly as follows:-The bar
I place on the inside of the door, and secure same free to revolve on a pin or pivot.
The bar is so formed that it projects on each side of the pin, or it may terminate
with the pin. To the other door is secured a handle or knob, which terminates
inside the door with a socket to receive one end of the bar. Locks are provided on
one door or on both the doors.
In carrying out my Invention I proceed thus:-The doors being closed, to lock
the same the knob or handle is turned, and with it the slotted piece or socket, in
such a position that on the bar falling one end drops into the slot. The slotted
piece drops down and the bar assumes a horizontal position. The lock on the door

page_text: is then turned, and the bolt is shot into such slot above or below the bar, and thus
same is securely held.
Sometimes a lock is also provided on the other door, and in this case the bar is
recessed, so that when the bolt is shot it enters the recess, and thus the bar is bolted
at each end.
To unlock the doors the locks are first turned and the bolts released, and then the
handle is turned, and with it the slotted piece, and the bar by its own weight falls,
thus releasing the doors.
It may be observed that in locking the bar is sometimes provided with a cord,
chain, or other means, the end of which passes through the door, by which means
the bar is raised into such a position as that when the slotted piece is turned into
proper position same is released, and the bar engages in the slot, and same is locked.
as before described.

CHARLES HENRY PARKIN, of New North Road, Hoxton, in the County of
Middlesex. IMPROVED ARRANGEMENTS FOR FASTENING AND SECURING DOORS
"
OR SHUTTERS."
My Invention consists of improvements in locking or securing and unlocking
doors, shutters, and such like, whether inside or outside, where a bar is used.
In the ordinary way doors are secured by a bar, which in the case of folding
doors is fastened to one of the doors, and when the doors are brought together such
bar, which is provided with an opening, takes into a ring fixed to the other door,
through which a padlock or lock is passed, and same is secured by locking in the
ordinary way. It is evident that by these means the lock can be wrenched off, and
thus the bar is released, and entrance obtained into the premises.
Now to obviate these defects I adopt improvements consisting as follows:-The
bar I place on the inside of the door, and secure same free to revolve on a pin or
pivot. The bar is so formed that it projects on each side of the pin, or it may
terminate with the pin. To the other door is secured a handle or knob, which
terminates inside the door with a socket to receive one end of the bar. Locks are
provided on one door or on both the doors.
In carrying out my Invention I proceed thus:-The doors being closed, to lock
the same the knob or handle is turned, and with it the slotted piece or socket, in
such a position that on the bar falling one end drops into the slot. The slotted
piece drops down, and the bar assumes a horizontal position. The lock on the door
is then turned, and the bolt is shot into such slot above or below the bar, and thus
same is securely held.
Sometimes a lock is also provided on the other door, and in this case the bar is
recessed, so that when the bolt is shot it enters the recess, and thus the bar is
bolted at each end.
To unlock the doors the locks are first turned and the bolts released, and then
the handle is turned, and with it the slotted piece, and the bar by its own weight
falls, thus releasing the doors.
It may be observed that in locking the bar is provided with a cord, chain; or
other means, the end of which passes through the door, by which means the bar is
raised into such a position as that when the slotted piece is turned into proper
position same is released, and the bar engages in the slot, and same is locked, as
before described.
Having thus far described the nature of the said Invention, and incidentally
intimated in what manner the same is to be performed or carried out in practice, I
will now proceed (aided by the accompanying Drawings) to further and particularly
describe and ascertain in what manner the same is to be performed or carried out
in practice, that is to say :-

page_text: through an opening in the door A when the bar is raised. This cord is for the
purpose of holding the bar, and when the doors are closed the cord is released, and
the bar falls into the socket F, and then is secured from the outside. This bar,
when in the position shown in Fig. 2, permits of the doors being freely opened and
closed. The doors A. being closed, the handle E is turned, and with it the socket F.
The bar C is then released, and falls, striking the socket F, which is then turned
into a perpendicular position, retaining the bar C horizontally, and the locks being
turned, pass into the slots c, c, and the doors A are secured.
To open the doors all that is required is to unlock the doors and then turn the
handle E in the reverse direction to that before described, and the bar C falls down
into the position shown by the dotted lines (see Fig. 1).
It is evident that single doors or shutters can be secured by my arrangements, the
bar C in this case being pivotted to the door post or other place, and the locking
being similar to that before described.
Having now particularly described and ascertained the nature and object of the
said Invention, and in what manner the same is to be performed or carried out in
practice, I hereby declare that I claim the Invention of "Improved Arrangements
for Fastening and Securing Doors or Shutters," substantially as herein-before set
forth and described and illustrated by the accompanying Drawings, wherein the
particular points are the arrangements of bar C and socket F as used in combination,
substantially as herein-before set forth and described.
In witness whereof, I, the said Charles Henry Parkin, have hereunto set my
hand and seal, this Fifth day of February, in the year of our Lord One
thousand eight hundred and seventy-nine.
Witness,
ERNEST HEMBER,
