I, GEORGE LOUIS VOGEL of 134th Street, New York City, U.S.A., Iron Worker, do
hereby declare the nature of this invention to be as follows:-
This invention relates to a fastener for shutters of the kind employed for ware-
houses, factories, office buildings and the like. The hinged shutters are connected
and rigidly held in position by a transverse brace formed of knuckle jointed sections,
namely, a middle section and two end sections, the brace being held in the closed
position of the shutters by a latch which may be raised and disengaged from the
middle section from the outside by means of a projecting knob so that the shutters
can be opened in case of fire. The end sections of the brace are pivotally connected
to upper shaped ends of pintles which are swivelled in ears attached to the inner
sides of the shutters and prevented from becoming detached from said ears by
enlarged heads or screw nuts at the lower ends of the pintles. In opening the
shutters the middle section of the brace is pressed down so as to form with the end
sections, a fastener by which the shutters are held in the open position. In closing
the shutters the brace is first raised from the locked into the unlocked position.

I, GEORGE LOUIS VOGEL of 134th Street, New York City, U.S.A., Iron Worker, 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 fasteners for shutters of the kind designed for warehouses,
factories, office buildings, and the like, where the shutters are locked in the open or
closed position whilst at the same time they may be opened from the outside in case
of emergency.
In the accompanying drawing Fig. 1 is a front elevation of the shutter fastener of
the invention applied to shutters and shewn in the open position. Fig. 2 a horizontal
section on line 2-2 of Fig 1. Fig. 3 a front elevation of a portion of the transverse
brace which connects and rigidly holds the hinged shutters and is shewn on an
enlarged scale. Fig. 4 a detail horizontal section of the knuckle joint between the
sections of the transverse brace on line 44 of Fig 3. Fig. 5 a front elevation of
'

page_text: the shutter fastener with one shutter open and the other in the act of being closed.
Fig. 6 a horizontal section on line 6-6 of Fig 5. Fig. 7 an enlarged view of a
portion of Fig. 6. Fig. 8 a front elevation of the device in dotted lines with the
shutters closed. Fig. 9 an enlarged detail section on line 9-9 of Fig. 8.
A are the shutters hinged in any suitable manner to the wall of a building. The
fastener is designed to connect the shutters and lock them in the open or closed
position, and comprises a transverse brace B formed in three sections namely a long
middle section b and short end section 61 connected with the middle section by
joints 62. The end sections are pivotally connected at do to the upper U-shaped
ends d¹ of pintles d which are swivelled in ears d² attached to the inner sides of the
shutters and prevented from becoming detached from said ears by enlarged heads d³
or screw nuts at the lower ends of the pintles. When the shutters are opened the
knuckle jointed brace B extends transversely across the window opening. The
middle section is pressed downward so as to form with the end sections b¹ a fastener
by which the shutters are firmly held in the open position which is caused by the
knuckle joints being then located below the pivots do and by the abutment of the
sections band b¹.
When it is desired to close the shutters the transverse brace B is first raised into
the position shewn in 'dotted lines in Fig. 1 so that the sections are moved from the
locked to the unlocked position whereupon one shutter is moved through an angle of
ninety degrees, thus raising the middle and opposite end section to an inclined
position whilst the end-section at the other end is raised (Fig. 5): The shutter is
further moved through another angle of ninety degrees until it arrives in closed
position. The opposite shutter A is then likewise moved through an angle of one
hundred and eighty degrees from its closed into its open position, by which the
end section b¹ and the middle section bare raised, as shewn in dotted lines in
Fig. 8. In this position, the middle section b of the brace is engaged by a pivotted
latch C guided within the keeper e at the inside of the shutter and which is
provided with a pin e¹ passing through a vertical slot e² of the shutter to the outside.
The locking portion or hook C₁ of the latch is arranged at right angles to its shank
and adapted to engage with the central section b so as to lock the brace in its closed
position, and thereby prevent the shutters from being opened from the inside or
outside except by first disengaging the latch from the middle section b.
When
If it should be necessary, as in case of fire, (the firemen not having access to
the building), the shutters can be readily opened from the outside by lifting the
outwardly projecting pin or knob of the latch C. This releases the latch from the
transverse brace B and permits the opening of one shutter after the other.
the shutters have to be opened for giving access to light and air, the latch is raised
from the inside, so as to be disconnected from the middle section of the brace B,
after which, one shutter and then the other can be readily opened, the knuckle
jointed brace following the changed position of the shutters, and when the brace
sections are in the position shewn in full lines in Fig. 1 the shutters are locked in
open position by the transverse brace B.
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 :-
1. The combination with hinged shutters, of a knuckle jointed brace extending from
shutter to shutter and consisting of a middle section, the two end sections, vertical
pintles journalled in suitable bearings on the shutters and to which the end sections
of the brace are pivotted, a brace latch applied to the inner side of one of the
shutters, and adapted to interlock with the middle section of the brace, and means
for operating the latch from the outside of the shutter, substantially as described
and shewn.
2. The combination with hinged shutters, of a knuckle jointed brace extending
transversely across the window from shutter to shutter, and being formed in three
sections, namely a middle section and two end sections, the end sections being

page_text: pivotted to the upper end of pintles swivelled to ears of the shutters, and a pivotted
latch applied to one of the shutters and adapted to engage the middle section of the
brace when the shutters are in closed position, said latch being provided with a pin
passing through to the outside of the shutter so as to permit a release of the latch
from the middle section of the brace when it is desired to open the shutters from
the outside, substantially as described and shewn.
