Improvements in or relating to Devices for Operating and Locking
Shutters, Jalousies, and the like.
A communication from AMEDÉE LAGARIGUE, Engineer, of 2 Rue du Pré,
Le Mans, in the Republic of France.
I, ALFRED JULIUS BOULT, of 323 High Holborn, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention to be as
follows:-
The object of the present invention is to construct apparatus enabling external
shutters or blinds to be opened or shut and locked from inside a room without
opening the window.
The apparatus comprises a "blind-closer" formed by an operating-bar provided
with a handle.
This bar is pivotally connected to the bottom of the blind, near the hinges of the
latter; it passes through the window sill or framing and enters into the room. A catch
is provided to enable the blind to be held fully open and a stop enables the blind to
be retained open to any desired lesser degree.
The stops are fixed at the bottom of the window inside the room. One stop is
carried in a bayonet-joint socket or otherwise arranged so that it can be brought
into or held out of engagement with a desired part of the operating bar. It is
preferably carried on a sliding carriage. A locking bar of any desired shape and
size slides on the outer face of the wall in proximity to the shutter, in suitable
guides. Stops are fixed to the shutter to engage with like stops on the
locking bar.
A rod extends through the wall, being carried in suitable bearinge, and provided
with a handle and cam, whereby it moves the locking-bar when rotated in its
bearings. The handle on this rod is within the room.
A covering box is preferably fixed at the bottom of the window case and protects
the blind-closers when they are moved into it.
All the mechanism can be of any metal.
Although I have hereinbefore described, by way of example, one construction of
apparatus according to this invention, I wish it understood that I may modify or
alter such apparatus without departure from this invention.
Dated this 5th day of February 1896.

I, ALFRED JULIUS BOULT formerly of 323 High Holborn now of 111 Hatton
Garden, in the County of Middlesex, Chartered Patent Agent, 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 shutter operating and locking device for enabling external shutters to blinds
to be opened or shut and, locked from inside a room without opening the window,
forming the object of the present invention, is illustrated in the accompanying
drawings in which,
Figure 1 is a perspective view of a window provided with the operating device
according to the present invention,
Figure 2 is a front view of one of the plates provided with stops;
Figure 3 is a plan of Figure 2.
Figure 4 is
horizontal section representing the mechanism in plan, view,
Figure 5 is a view of the latch.
Each complete lever of the shutter closing device consists of two branches a
and 6 one of which, a, slides in a mortice e formed in the window sill or frame and
is hinged at d to the second, which latter is secured to the shutter; the branch a
ending in a handle a¹.
e
with slots
In the interior of the apartment are screwed two plates
corresponding to mortices c. Each of these two plates is provided with two
stops.
The stop (Figure 2) consists of a vertical latch, which, when the shutters
are fully open, falls into a notch g of the branch a and holds the shutter in
position.
The stop is adjustable by means of slides i; and consists of a latch j operated
by means of a knob k sliding in a right angled groove l; the bolt j of the latch
engages with any desired hole m made in the branch a, for the purpose of
maintaining the shutters in the desired position; the hole nearest to the handle
receives the bolt j when the shutters are completely closed, thus affording a safety
catch.
In this case the two branches a b take the position represented in Figure 4, and
their hinge-joints comes into the recess in the wall where they may be protected,
by an overlapping casing t, against the dampness of the brickwork.
A lever n, the handle of which is in the interior of the apartment, and the outer
part of which is secured or guided as at o enables a, latch p of, any desired shape or
size to be raised by means of a cam g. The latch shown in Figure 5 is mounted on
the piece at the meeting edges of the two shutters by clamps r; two catches &
fixing the shutters at the top and in the centre.
Having now particularly described and ascertained the nature of the said inven-
tion as communicated to me by my foreign correspondent and in what manner the
same is to be performed, I declare that what I claim is :-
1. A device enabling shutters to be opened and closed from the interior of the
apartment without opening the window, consisting of hinged levers one branch of
the lever being secured to the shutter, the other passing through the window sill

page_text: or framing and entering the apartment where it may be secured by stops or catches,
in a completely or partially open or closed position.
2. In a device as described in Claim 1, a lever n enabling the latch to be acted
upon from the interior in order to secure the shutters in a closed position.
