PROVISIONAL SPECIFICATION.
A Device for Securing Exterior Window Shutters and the like.
We AUGUSTE CAZALOU and GABRIEL PIERRE JOSEPH DE TAMANHAN both
of 7 Rue de Berry Bordeaux in the Republic of France, Manufacturers do hereby
declare the nature of this invention to be as follows:-
--
The object of this invention is to provide a device for securing exterior window
shutters, Venetian shutters and like door-like or hinged flaps or constructions when
elsed and retaining such shutters or the like in their closed position so that they
cannot become accidentally unfastened, or be otherwise unfastened without the
inner window or the like has been previously opened to afford access to the fastener.
The fastener comprises a base plate and a tongue hinged thereto, the base plate
is intended to be fixed upon the inside of the shutter at a suitable distance from the
hinges, the tongue is made long enough to extend across the space intervening
between the shutter and the window and has a slot in the end to pass over a turn
button or stud the base plate or holder of which is secured to or in a recess in the
window frame in such a way that when the window is closed the button or stud
cannot be reached nor therefore the tongue unfastened if fastened.
If the space between the window and shutter is long, the tongue may be provided
with a slot and its own base plate be provided with a stud or turn button to enter
the said slot when the tongue is folded back against the shutter and secure the tongue
in such position while the shutter is open.

A Device for Securing Exterior Window Shutters and the like.
We AUGUSTE CAZALOU and GABRIEL PIERRE JOSEPH DE TAMANHAN, both
of 7 Rue de Berry, Bordeaux in the Republic of France, Manufacturers 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 object of this invention is to provide a device for securing exterior window
shutters, Venetian shutters and other door-like or hinged flaps or constructions
when closed and retaining such shutters or the like in their closed position so that
they cannot become accidentally unfastened or be otherwise unfastened without
the inner window or the like has been previously opened to afford access to the
fastener.
•
The fastener comprises a base plate and a tongue hinged thereto, the base plate
is intended to be fixed upon the inside of the shutter at a suitable distance from
the hinges, the tongue is made long enough to extend across the space intervening
between the shutter and the window and has a slot in the end to pass over a turn
button or stud the base plate or holder of which is secured to or in à recess in the

page_text: window frame in such a way that when the window is closed the button or stud
cannot be reached nor therefore the tongue unfastened if fastened.
If the space between the window and shutter is long, the tongue may be provided
with a slot and its own base plate is provided with a stud or turn button to enter
the said slot when the tongue is folded back against the shutter and secure the
tongue in such position while the shutter is open.
In the annexed drawing ;-
Fig. 1 is a vertical section through the longitudinal axis of the fastener.
Fig. 2 plan view of the fastener detached.
Fig. 3 a perspective view of the same when attached.
This fastener is in two parts viz.: the base plate A and the tongue B.
The plate A is fixed on the one stile of a window shutter or of a fan light
shutter D by means of two screws at the upper part and at their lower part by
means of two rivets of conical shape arranged.about to g of an inch distant from
the hinge. Where walls of 11 inches or more in thickness are met with a turn
button C is arranged on the base A and serves to hold the tongue B when folded
against the base A.
For shutters mounted on outstanding hinges this turn button is omitted' because
of the distance between the window shutter and the sill F is very short. The
tongue B resting upon the sill is provided at its extremity and at about its middle
with oval shaped holes d and e respectively.
The oval hole d serves to connect the tongue B with the sill by means of a pin f
embedded in a notch in said sill. When the window sash or casement is closed over
the recess d it will confine the tongue on the pin f, thus rendering this system a
safety fastener.
The oval hole d'owing to its elongated' form allows of the swelling of the wood
of the shutter.
The oval hole e provided in the centre of the tongue B serves in walls of 11 inches
or more in thickness as a passage hole for the turn button C on the base A.
Having now particularly described and. ascertained the nature of this inven-
tion and. in what manner the same is to be performed, we declare that what we
claim is::-
1. The combination with a pin f in a recess in a window sill adapted to be
covered by the window sash or casement, of a tongue secured to an exterior
shutter or the like adapted to engage said pin for the purpose set forth.
2. The combination with base plate A of the tongue B hinged thereto, elongated
slots d and e iu said tongue and a turn button C. in said base plate, the whole for the
purpose set forth.
