Year: 1862

page_text: LETTERS PATENT to George Lawrence Lec, of Holborn Hill, in the City
of London, Lithographic Artist, for the Invention of "IMPROVEMENTS IN
THE MANUFACTURE OF METALLIC SHUTTERS FOR SHOP FRONTS, DOORS, AND
WINDOWS."
Sealed the 18th March 1868, and dated the 16th September 1862.
PROVISIONAL SPECIFICATION left by the said George Lawrence Lee
at the Office of the Commissioners of Patents, with his Petition, on
the 16th September 1862.
I, GEORGE LAWRENCE LEE, of Holborn Hill, in the City of London,
Lithographic Artist, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE MANUFACTURE OF METALLIC SHUTTERS FOR SHOP FRONTS,
DOORS, AND WINDOWS," to be as follows:-
This Invention consists of a novel construction of metallic shutters to be
used in lieu of the revolving shutters at present in use; the expense of the
latter, owing to the complication of machinery, whereby they are actuated, and
their liability to require constant repair and attention, rendering them beyond
the means of the generality of shopkeepers. Now I propose to construct
shutters of sheet metal either plain, corrugated, fluted, or zig-zagged in
divisions or sections of any desired width, the edges thereof being turned over
and doubled for strength, and one side or edge of the shutter being perforated
with circular holes and slots, and the corresponding opposite edges of the
shutters having studs with button beads fixed thereon, so as to enable them

page_text: to enter the holes and slots. The shop front or window is to be provided
with a groovo or bar at the top and bottom thereof, and running the entire
length of the window or front, so as to form a groove or rabbet into which
the shutters are placed; the first of which should have studs projecting
parallel with the surface of the shutter, in order to enter corresponding
apertures in the upright portion of the frame of the window or front whereby
the edge of such shutter is held in position, the next shutter is then inserted
in the grooves, the projecting heads of its edge being passed behind and
through the holes in the edge of the first and then drawn a small distance
back, so as to bring the slot under the button or head of the stud and secure
the fastening of both, thus the entire row or series of shutters may be con-
nected and secured together; the outer edge of the last shutter being held in
position and secured by an upright bar perforated with one or more holes, the
shutter being similarly perforated, and the bar being held by a bolt passing
through the two and through the upright frame of the window, and by thumb-
screws or otherwise inside the window.
I
Another arrangement of shutter for doors and for windows of private houses,
propose to construct of a series of slips of sheet metal hinged together, so that
they may fold up in a narrow compass, there would be two shutters each half
the width of the door or window, and they should be secured to the opposite
sides of the frame or the door jamb by means of hinges or springs, they may
then be unfolded and drawn together in the middle of the door or window
and secured by locks, bolts, or other fastening. If a recess were cut in
the door jamb or the frame of the window the shutters could be attached
therein, so as when folded up to be concealed from view. By this Invention
all the security and appearance of the revolving shutters can be obtained
with less complication and expense and with no liability of getting out of
order.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Lawrence Lee in the Great Seal Patent Office 3
on the 16th March 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
LAWRENCE LEE, of Holborn Hill, in the City of London, Lithographic Artist,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters s
Patent, bearing date the Sixteenth day of September, in the year of our Lord

page_text: One thousand eight hundred and sixty-two, in the twenty-sixth year of Her
reign did, for Herself, Her heirs and successors, give and grant unto me,
the said George Lawrence Lee, Her special licence that I, the said George
Lawrence Lee, my executors, administrators, and assigns, or such. others as
I, the said Georgo Lawrence Lee, my executors, 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
"IMPROVEMENTS IN THE MANUFACTURE OF METALLIC SHUTTERS FOR SHOP FRONTS;.
DOORS, AND WINDOWS," upon the condition (amongst others) that the said
George Lawrence Lee, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should par-
ticularly 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said George Lawrence Lee, do hereby
declare the nature of my said Invention, and in what manner the same is.
to be performed, to be particularly described and ascertained in and by tho
following statement :-
This Invention consists of a novel construction of metallic shutters to be used
in lieu of the revolving shutters at present in use, the expense of the latter,
owing to the complication of machinery whereby they are actuated and their
liability to require constant repair and attention, rendering them beyond the
means of ordinary shopkeepers. Now I propose to construct shutters of sheet
metal either plain, corrugated, fluted, or zig-zagged in divisions or sections of
any desired width, the edges thereof being turned over and doubled for strength,
and also, if required, for the purpose of forming a rabbet joint to same.
shop front or window is to be provided with a groove or bar at the top and
bottom thereof, and running the entire length of the window or front, so as to
form a groove or rabbet into which the shutters are placed; likewise an
upright groove or bar to receive the edge of the first shutter where occasion
requires.
The
One method, according to my Invention, is represented in the Drawing
hereunto annexed, Fig. 1. The first shutter a to be placed in position would
have a simple straight stud or studs or a stud or studs with button heads b
fixed thereon to one edge projecting parallel with the surface of the shutter, in
order to enter a corresponding aperture in the upright portion of the frame of

page_text: the shop front or window whereby the edge of such shutter is held in position,
the opposite edge of the said shutter would be perforated to receive the stud
of the adjoining shutter, and so on, until tho last which would be without a
stud, but would be provided with one or more thumbscrews or bolts, which
would pass through the shutter and through the upright frame of shop front
or window and bo secured thereto, thus the entire row or series of shutters
may be connected and secured together; or, if necessary, the ordinary shutter
bar can be adopted.
By another method, according to my Invention, I propose to lap or rabbet-
joint the connecting edge of these shutters in any or all of the forms repre-
sented in Drawing. Sections, Figures 2, 3, 4, and 5, which are horizontal
sections; and here I would either use or dispense with the studs before
described. These shutters would all be raised at the end to be occupied by
the last shutter, greater height at this place being provided to enable the
shutter to pass over the top edge of the lower groove, and by dropping into
same can be pushed along into its proper place; the last shutter would be
provided with one or more thumb screws or bolts, which would pass through
the shutter and through the upright frame of shop front or window and be
secured thereto as before described; or, if necessary, the ordinary shutter bar
can be adopted. The elevation, Fig. 6, represents a shop front partly closed
with the shutters before described.
Another arrangement of shutters for doors and for windows or private
houses, I propose to construct of the like sheet metal either plain, corrugated,
fluted, or zig-zagged in divisions or sections of any desired width, as repre-
sented in sections, Figs. 7 and 10, being a series of slips of metal hinged
together, so that they may fold up in a narrow compass. There would bo two
shutters, each about half the width of the door or window, and they should
be secured to the opposite sides of the window frame or door jambs by means
of hinges or springs; they may then be unfolded and drawn together in the
middle of the door or window and secured by locks, bolts, or other fastenings.
If recesses are formed in connection with the door jambs or the frame of the
window the shutters could be attached therein, so as when folded up to be
more or less concealed from view. Sections, Figs. 8 and 9, represent two
methods of binging these shutters. By this Invention all the security and
appearance of the revolving shutters can be obtained with less complication
and expense, and with little liability of getting out of order.
Having now described the nature of my said Invention, and the manner
in which the same is to be performed, I would remark in conclusion that I
do not limit myself to the precise details and configuration of parts herein

page_text: expressed & shewn; but what I claim is the manufacture of metallic shutters
in the manner herein described and illustrated by the Drawings hereunto
annexed.
In witness whereof, I, the said George Lawrence Lee, have hereunto
set my hand and scal, this Fourteenth day of March, in the year
of our Lord One thousand eight hundred and sixty-three.
