JOHN SIMEON MARYON, of Highgate Hill, in the County of Middlesex.
PROVEMENTS IN THE MEANS OR SHUTTERS EMPLOYED FOR CLOSING, SECURING,
AND PROTECTING WINDOWS, DOORS, OR OTHER APERTURES.”
This Invention relates to improvements in the shutters or means employed for
closing and securing windows, doors, or other apertures.
In place of employing ordinary shutters for closing, securing, and protecting shop
and other windows or doors, it is not unusual to protect them by means of an open
frame-work of bars, so that the interior of the shop, warehouse, or room, may be
seen through the spaces between the bars.
Now the object of my Invention is to arrange and apply a latticework of bars of
metal or other material jointed together, so as to expand and contract in like
manner to what are known as lazy-tongs.
For this purpose in order to close or protect a window or other aperture, I find
it advantageous to arrange the lattice-work of bars in two parts or halves, the
outer jointed ends of the bars entering into and being guided in a groove on each
side of the window or other opening. When the lattice-work of bars is expanded
or drawn out to its fullest extent, it serves as an open work shutter to close and
protect the window or aperture, and when contracted it may either be arranged to
ascend or descend into a recess behind a screen, or the lattice-work may be Bo
arranged as to be removed when out of use.
The lattice-work of bars may be arranged in one or more parts according to the
purpose for which it is required.
Lattice-work shutters, such as above described, may be rendered self acting by
means of springs, weights, or otherwise, if desired.
For some purposes I combine a series of light steel bars or wires connected
together, and when expanded the elasticity of such bars or wires admits of their
being drawn over the window or aperture to be closed or protected.

page_text: Figure 6 shows a plan in section on a larger scale of the fixed guide s and pin a³,
rivetted to the outside joints of section a to guide the movement of the bars when
they are opened or closed. A similar fixed guide s is required for guiding the
outer joints of section c, and another of such guides is also required to guide the
jointed ends at the top or bottom of each section, according to whether the shatter
is arranged to pass upwards or downwards when out of use.
Figure 7 shows a section of the bars taken through one of the joints, each being
advantageously formed of trough shape, as shown.
Portable sections of bars combined together so as to expand diagonally as
previously described may if desired be placed and secured in position by any
convenient means, and be removed elsewhere by hand when out of use.
Having thus described the nature of my Invention and the manner of performing
or carrying the same into practice, I would observe that I do not claim any of the
parts separately which are well known and in use, nor do I confine myself to the
exact details herein before described, so long as the novel character of my Invention
is retained, but what I claim is,—
The improved arrangement and combination of jointed expanding and con-
tracting bars, and the application thereof for the closing, securing, and protecting of
windows, doors, and other like apertures, substantially in the manner hereinbefore
described and represented in the Drawings hereto annexed.
I also claim the improved arrangement and combination of the several sections
a, b, c, of jointed bars, the guide rods d, and fixed guide e, all arranged to act
substantially in the manner and for the purpose herein before described and
represented in Figures 4, 5, and 6, of the Drawings hereto annexed.
In witness whereof, I, the said John Simeon Maryon, have hereunto set my
hand and seal, this Twenty ninth day of December, in the year of our
Lord One thousand eight hundred and seventy nine.
