1, MARY PHILLIPS, of Birmingham, in the County of Warwick,
Widew, do hereby declare the nature of the said Invention for "AN

SHUTTERS," Communicated to me by iny late husband, to be as follows:-
The said Invention consists in an improvement or improvements in
connecting or jointing together the metallic strips or laths of which the
said shutters are composed. Figure 1 represents in front view a por-
tion of a shutter constructed according to the said Invention; Figure 2
represents the same in vertical transverse section; and Figure 3 repre-

page_text: sents a portion of the same in an unfinished state, the said Figure 3,
being also in transverse vertical section. Figure 4, illustrates the
winding of the shutter on a roller; a, a, are the laths or strips of which
the shutter is composed; the longitudinal edges of these strips are bent
into a nearly cylindrical form, as shewn at b, b, Figure 3. The said
bending may be effected by the process called "drawing," or by any
of the other well-known processes by which metals may be shaped.
The strips are then presented to each other end to end, the lower cylin-
drical edge of one strip being presented to the upper cylindrical edge of
another, and the said cylinders are made to slide on one another, as
illustrated in Figure 3. The said strips are thus jointed or connected
with one another, and can only be separated by sliding longitudinally.
The joint may, however, be made more complete by the introduction of
a wire or axis, as shewn at c, Figure 2.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Mary Phillips in the Great Seal Patent Office
on the 23rd June 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
MARY PHILLIPS, of Birmingham, in the County of Warwick, Widow,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-ninth day of December, in the
year of our Lord One thousand eight hundred and fifty-three, in the
seventeenth year of Her reign, did, for Herself, Her heirs and succes-
sors, give and grant unto me, the said Mary Phillips, Her special
licence that I, the said Mary Phillips, my executors, administrators,
and assigns, or such others as I, the said Mary Phillips, my execu-
tors, administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "AN IMPROVEMENT

nunicated to me by my late husband, upon the condition (amongst
others) that I, the said Mary Phillips, by an instrument in writing
ander my hand and seal, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said Mary Phillips, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof (that is to say) :-
The said Invention consists of an improvement or improvements in
the method of connecting or jointing together the m:tallic strips or
laths of which metallic winding or revolving shutters are composed.
Figure 1 represents in front elevation a shutter constructed according
to the said Invention; Figure 2 represents a vertical section of the
same, the said section being taken through the line a, Figure 1;
Figure 3 represents horizontal section of the same, taken through the
line b, Figure 1; Figure 4 represents a detached portion of the same.
c, c, are the laths or strips of metal of which the shutter is composed,
which said laths or strips I prefer to make of iron, but do not limit
myself thereto. The width and length of the said strips, as well as the
thickness of the metal of which they are made, may be varied. The
longitudinal edges of the strips c, c, are bent into a nearly cylindrical
form, as shown at d, Figure 4; and the strips themselves are slightly
curved, as is also shewn in Figure 4. The said bending of the edges
of the strips, as well as the curvature in the said strips, may be effected
by the process called "drawing," or by any of the other well-known
The said strips are put
processes by which metal may be shaped.
together so as to form a winding shutter in the following manner: —
The two strips to be joined are presented to each other end to end,
the lower cylindrical edge of one strip being presented to the upper
cylindrical edge of the other, and the said cylindrical edges are made
to slide on or engage with one another, in a manner which will be

page_text: readily understood by an inspection of Figure 4. Any number of strips
or laths may be joined together in the manner described, so as to con
stitute a shutter of any desired length. I prefer introducing a wire or
axis e, Figure 4, into the joined cylindrical edges of the strips or laths.
the said wire or axis extending the whole length of the said strips or
laths. The said wire or axis may, however, be omitted, where light-
ness is required, with little injury to the perfection of the joint. The
manner in which I apply the said Invention to the closing of windows,
doors, and such other openings as the same is or may be applicable to,
will be understood by an inspection of Figures 1, 2, and 3.
Having now described the nature of the said Invention, and the
manner of carrying the same into effect, I wish it to be understood that
I do not limit myself to the precise methods herein described, and illus-
trated in the accompanying Drawing, as the same may be varied without
departing from the nature of the said Invention; but I claim as the
said Invention, the methods herein described, and illustrated in the
accompanying Drawing, of connecting or jointing together the metallic
strips or laths of which metallic winding or revolving shutters are com-
posed; that is to say, by bending the edges of the said strips or laths
into a cylindrical or nearly cylindrical form, and causing the bent edges
of the said strips or laths to slide upon or engage in one another, either
with or without a central axis.
In witness whereof, I, the said Mary Phillips, have hereunto
set my hand and seal, this Twenty-second day of June, in the
year of our Lord One thousand eight hundred and fifty-four.
Witness,
GEORGE SHAW.
