Improvements in Devices for Fastening and Unfastening
Window-shutters.
A communication from abroad by JOHN MILTON CORNELL, of 26th Street and
11th Avenue, in the City of New York, in the State of New York, United
States of America, Manufacturer.
I, JOHN CORRY FELL, of the firm of Fell and Wilding of 1 Queen Victoria
Street in the City of London, Patent Agents, do hereby declare the nature of
the said invention for "IMPROVEMENTS IN DEVICES FOR FASTENING AND
UNFASTENING WINDOW-SHUTTERS," 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 those shutter-fastenings which may be and are used
alternatively to hold the shutters open, as well as to secure them against being
blown open when closed or to fasten them against being opened from outside.
The present improvements consist in the combination of a telescopic shutter-bar
with (1) a fastening catch, or preferably a pair of such catches, having a pro-
truding and paddle-shaped outer end against which a stream of water or a fireman's
rod may be directed to unfasten the shutters of an elevated window in case of a fire
within, with or without springs to coact with said bar for opening the unfastened
shutters; and with (2) a fastening catch for each shutter or pair of shutters of
lower or more exposed windows; the whole constituting an improved system of
fastening and unfastening devices for the window-shutters of a warehouse or like
building.
A sheet of drawings accompanies this Specification as a part thereof.
Figure 1 is an outside view of an open window the shutters of which are provided
with the aforesaid shutter-bar, fastening-catches and opening-springs for the shutters
of elevated windows.
Figure 2 is another outside view of the same window showing its shutters closed
and fastened.
Figure 3 represents a section through the closed shutters on the line 3-3
Fig. 2.
Figures 4 and 5 are fragmentary views, including respectively plan and side
views of one of said fastening-catches, and illustrating their operation.
Figures 6 and 7 are fragmentary views, including respectively plan and edge
views of one of said opening-springs.
Figure 8 is an outside view of an open window the shutters of which are
provided with said shutter-bar and fastening-catches for lower or more exposed
windows.
Figure 9 is an inside view of said window Fig. 8 showing its shutters closed and
fastened.
Figure 10 is a sectional elevation of a shutter-bar detached.
Figures 11 and 12 are fragmentary views, including respectively side and end
views of one of the fastening catches last named.
Figs. 1 2 3 8 and 9 are drawn to one and the same scale, and Figs. 4 5 6 7 10 11
and 12 are enlarged therefrom one diameter.
Like numbers and letters refer to corresponding parts in all the figures.
Referring first to said Figs. 1 to 7 inclusive and Fig. 10-A A² represent a
pair of shutters swinging horizontally on hinges 13 in a customary way. B represents
rod," which may be
a telescopic shutter-bar composed of a gas-pipe "tube" and a
of smaller gas-pipe, sliding within said tube; said tube and rod being attached by
hinges 14 and 15, to those surfaces of the shutters which are inside when the
TD011

page_text: shutters are closed, and preferably at mid-height, as in Fig. 1. The tube of this
shutter-bar is provided with a hole 16 Fig. 10, in which a locking pin 17 is
inserted to keep the bar extended, and thus to hold the shutters open as in Fig. 1 ;
such pin being conveniently attached to the shutter-bar by a short chain 18.
CC represent fastening-catches to interlock with the tube of the shutter-bar B
when the shutters A A' are closed, as in Figs. 2 to 5, having protruding and paddle-
shaped outer ends 19, as aforesaid, and attached to the shutters by hinge-brackets 20;
the shank of each catch extending through a vertically elongated slot, 21 Fig. 5, in
the shutter, and its hooked nose-end engaging with the shutter-bar from beneath
upward, so that upward pressure against the paddle-shaped outer end 19, as indicated
by the arrow a Fig. 5, disengages the catch C, from the shutter-bar B, as shown in
dotted lines in said Fig. 5, and thus unfastens the shutters. The preponderating
weight of the outer end 19 tends to maintain the catch in its fastened position.
nose-end is bevelled at 22 Fig. 5 so as to enable the shutter-bar to depress it
automatically when the shutters are closed. DD, Figs. 1 3 6 and 7, represent
opening-springs attached fixedly to the shutters A A² so that they are compressed
behind the bur B when the shutters are closed as in Figs. 2 and 3.
When the
outer shutter A is unfastened by pushing upward the outer end of its catch C, its
spring D, coacting with the bar B, immediately forces and holds the shutter open
to a sufficient extent to keep it from becoming automatically refastened. The
shutter A2, if likewise provided with a catch C as shown, may then be unfastened
and opened in like manner. Springs otherwise applied, or any other approved device,
may be substituted for said springs D for so opening the shutters. E E represent
rings by which to pull the shutters closed.
Its
For such rings any approved form of handle or hand-hold may obviously be
substituted if preferred.
Referring now to Figs. 8 and 9 and Figs. 11 and 12:-A A2 in these figures
represent a pair of shutters, B a shutter-bar and E E closing rings, all of which
may be similar to those above described. The shutter-bar and its accessories are
shown at the bottom of the shutters in this case. They may be located either at
the bottom or at mid-height as may be preferred. C'C' represent fastening-catches,
interlocking with the tube of the shutter-bar B when the shutters A A² arc closed,
as in the foregoing arrangement, but located wholly inside of the shutter so as to be
inaccessible from outside, attached by hinge-brackets 23, Figs. 11 and 12, and
provided with bevels 24, Figs. 11 and 12, to engage with the bar, stops 25,
Figs. 11 and 12, coacting with said brackets 23 in any approved way to support
the catches so that said bevels shall be in the plane of the bar to engage there-
with, and locking-buttons 26, Figs. 11 and 12, by which to fasten the catches
down, as in Figs. 9 and 12 and in full lines in Fig. 11 when the shutters are closed.
The shutters are fastened in both arrangements by simply closing them by
means of their rings E, after withdrawing the pin 17 of the shutter-bar B;
the catches C or C₁ engaging automatically with the bar when the latter comes
in contact with their bevels 22 or 24, and assuming their fastened positions by
gravitation.
In the first arrangement, Figs. 1 to 7, the shutters may be unfastened by
depressing the nose-ends of the catches C by the finger, so that the opening-
springs D or their equivalents may operate; but are distinctively adapted to
open automatically when unfastened by tripping the catches C from outside by a
stream of water or a fireman's rod or pole acting against their said paddle-shaped
outer ends, as in Fig. 5.
In the second arrangement, Figs. 8 to 12, the catches C¹ must first be unfastened
by turning up their buttons 26, after which the catches as a whole are lifted and
may be thrown back against the shutter as in dotted lines in Fig. 11. (They may
be lowered by hand in the fastening operation if preferred, and in this case their
bevels 24 and stops 25 may be omitted.)
When the unfastoned shutters are pushed wide open, the pin 17 in inserted in the
hole 16 of the shutter-bar B, as in Figs. 1 and 8.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
(1) In combination with a pair of horizontally swinging shutters, a telescopic
shutter-bar hinged to the respective shutters, and a fastening catch or a pair of
such catches interlocking with said shutter-bar and having protruding paddle-shaped
outer ends, substantially as hereinbefore described with reference to Figs. 1 to 5
inclusive and Fig. 10 of the accompanying drawings.
(2) The combination with the said shutters, shutter-bar, and catches, of opening-
springs coacting with said shutter-bar to partly open the unfastened shutters,
substantially as hereinbefore described with reference to Figs. 1 to 3 and
Figs. 6 and 7.
(3) The alternative arrangement for lower or more exposed windows shown
in Figs. 8 and 9 and Figs. 11 and 12, comprising a fastening catch C'having a
locking-button 26, or a pair of such catches, substantially as hereinbefore
described.
