Improvements in and relating to Fastenings for Doors.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, do hereby
declare the nature of this invention to be as follows:-
This invention relates to fastenings for doors.
By the improved device constructed according to the said invention street
doors, cupboard doors, and the like, and especially folding or double doors, may
be securely fastened so as to defy any attempt at breaking them open when the
inhabitants are absent from the house and where a padlock would only serve to
indicate such absence to burglars.
To one of the door posts an iron bar is fixed at one of the ends by means
of an iron ring in such a manner that it can be freely moved in all directions.
This iron bar rests with its other end, when the door is closed, in a hook or
staple arranged upon the second door post, whilst an iron band, fixed by the side
of or below the lock by means of a hinge and a hook or the like, serves as a
guide for the said iron bar. By the side of the guide the iron bar is provided
with a hole or eye with which engages a chain, a metallic or other cable. The
chain or metallic cable, by a lever fixed above the lock of the door or by a
pulley, is connected with a short piece of wire or metallic rod provided in an
aperture which is pierced in the door. This metallic rod has at its end an eye
or a screw-thread, which must also be in the interior of the wood.
For raising the iron bar in order to open the door a piece in the form of a
key provided with small hooks or with corresponding screw threads is introduced
into the aforesaid aperture; when this key has been passed into the eye or when it
has been screwed upon the rod, a traction is exerted upon the said rod in order to
remove the iron bar from the hook or staple, thus facilitating the opening of the door.
In lieu of the aforesaid lever use may also be made of a spindle, the
arrangement being such that the iron bar will be raised, not by pulling the
aforesaid rod, but simply by turning the screw or the key, thereby winding
the chain or cable a little upon a pulley and unwinding it again by the weight of
the iron bar when the key or the screw is pulled out. By employing different
screw threads and varying the keys as in the case of keys for locks, any number
of variations may be obtained.
To the bar may also be applied any suitable device which on the bar being
raised actuates an electric bell which rings as long as the iron bar is kept raised.
In case the fastening is not used during the day the iron bar may be suspended
or put aside.

Improvements in and relating to Fastenings for Doors.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 fastenings for doors.
By the improved device constructed according to the said invention street doors,
cupboard doors, and the like, and especially folding or double doors, may be
securely fastened so as to defy any attempt at breaking them open when the
inhabitants are absent from the house and where a padlock would only serve to
indicate such absence to burglars.
In the accompanying drawing
Figure 1 represents the apparatus so arranged on the interior side of the door,
while
Figure 2 shows a detail view of said device.
In carrying the said invention into practice I secure an iron bar a at one of its
ends to one of the posts of the door by means of an iron ring b in such a manner
that it can be freely moved in all directions. This iron bar rests with its other end,
when the door is closed, in a hook or staple e arranged upon the second door post,
whilst an iron band d fixed by the side of or below the lock by means of a hinge
and book or the like, serves as a guide for the said iron bar. By the side of the
guide the iron bar is provided with a hole or eye e through which passes a chain,
a metallic or other cable. The chain or metallic cable f, by a lever g fixed above
the lock of the door (Figure 2) is connected with a short piece of wire or metallic
rod provided in an aperture K which is pierced in the door. This metallic rod
has at its end an eye or a screw thread, which must also lie within the thickness
of the wood.
For raising the iron bar in order to open the door I introduce into the opening K
a piece in the form of a key to engage with the eyes or screw threads; when this
key enters into the eye or when it has been screwed upon the rod, by a traction or
a. pull upon the said rod, it removes the iron bar from the hook or staple c into the
position shown in dotted lines in Figure 1, thus facilitating the opening of
the door.
To the iron bar may also be applied any suitable device which on the bar being
raised actuates an electric bell which rings as long as the iron bar is kept raised.
In case the fastening is not used during the day the iron bar may be suspended
or put aside.
...Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is :-
A fastening device for doors arranged on the interior thereof and adapted to
be operated from the exterior, pivoted on one side so as to turn upon a door post
and on the other side engaging with a staple c; the bar being raised out of
engagement with the staple c by a chain, wire or metallic cable, crank, lever by
means of a traction or pull exerted by the aid of a suitable key introduced into
a hole pierced in the door, which key engages with a screw, an eye or the like
terminating the rod for permitting the opening of the door.
