I, the said Marmaduke William Hallett, my executors or administrators, by
an instrument in writing under my, or their, or one of their hands and seals,

This Invention consists in an improved arrangement of apparatus for
securing windows and other openings in buildings. For this purpose vertical
bars are employed, and these bars are ranged at a short distance apart across
the window or opening to be secured, as when ordinary fixed bars are employed';
but in place of being permanently fixed at a distance apart, they are connected
or jointed together, so that they can be folded or brought close to each other, s
and packed out of sight in the spaces at the sides of the window or other
opening where shutters are usually fitted.....

page_text: Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.
DESCRIPTION OF THE DRAWING.
Figure 1 shews by dotted lines, in elevation, an opening in a building
suitable for a window, door, or otherwise, the bars being shown folded within
the mouldings or frame surrounding the opening.
Figure 2 shows another view of the same opening where the bars are
expanded, so as to close the opening in such manner as to prevent the passage
of a person through such opening.
Figure 3 shows a transverse section of the apparatus. The system on which
the apparatus is made is that of the parallel rule, so that the bars a, a, of
which the apparatus is principally formed, are constantly parallel to each
other, and they are kept parallel by the links or connecting rods c, c, which at
their ends are pin-jointed to the bars a, a, a, the ends of the outer ones
being pin-jointed to other links c', which are pin-jointed to the uprights d, d, of
the rectangular fixed frame d, d; and in order that the bars a, a, a, may be
moved freely in and out, some of them are provided with wheels or rollers e, e,
at their ends, which run on the horizontal bars d, d, of the fixed frame d, d, as
is shown.
In order that the system of bars thus applied to window and other openings
of buildings may be secured when closed, a lock or other fastening is to
be applied in each case, the form of which may be greatly varied; in the
Drawing one is shewn with a forked bolt, which retains two of the bars a, a,
from being moved back till the bolt is withdrawn.
Having thus described the nature of my Invention, and the manner of per-
forming the same, I would have it understood that I make no claim to any
of the parts separately, nor do I confine myself to the precise details; but
what I claim is the combination herein described.
In witness, whereof, I, the said Marmaduke William Hallett, have
hereunto set my hand and seal, this Thirteenth day of August, in the
year of our Lord One thousand eight hundred and fifty-seven
Witness,
MATTHEW OLIVER.
