IMPROVEMENTS IN REVOLVING OR COILING SHUTTERS, AND IN WINDOW PROTECTORS
Year: 1878

page_text: LETTERS PATENT to Noah Greening and John Greening, both of Warrington,
in the County of Lancaster, Wire Manufacturers, for the Invention of
"IMPROVEMENTS IN REVOLVING OR COILING SHUTTERS, AND IN WINDOW
PROTECTORS."
Sealed the 6th June 1879, and dated the 9th December 1878.
PROVISIONAL SPECIFICATION left by the said Noah Greening and John,
Greening at the Office of the Commissioners of Patents on the 9th December
1878.
NOAH GREENING and JOHN GREENING, both of Warrington, in the County of
Lancaster, Wire Manufacturers. "IMPROVEMENTS IN REVOLVING OR COILING
SHUTTERS, AND IN WINDOW PROTECTORS."
We take a series of round metallic rods and connect the same together at equal
distances apart and parallel to each other by means of a series of metallic wire
coils. These coils are made by twisting the wire (say by preference of iron or steel)
several times round a mandril, and then continuing the wire across to another
mandril set at the desired distance apart, and round which the wire is again coiled
in the same or in the reverse direction to the previous coil, when it is once more
brought back and coiled round the first mandril and the same operation repeated
until the desired width of coil is obtained.
These alternating coils are then interlaced similar to hinge joints, and held
together by the rods being passed through them, and thus when secured in position
a metallic shutter or open grating is produced capable of being wound upon a
roller and otherwise mounted in the same manner as the closed revolving or coiling
lath shutters now in use.
This Invention also affords a protection to a window without concealing from
view the contents of the shop or other apartment to which the window
appertains.

the said Noah Greening and John Greening in the Great Seal Patent Office
on the 9th June 1879.
NOAH GREENING and JOHN GREENING, both of Warrington, in the County of
Lancaster, Wire Manufacturers. " IMPROVEMENTS IN REVOLVING OR COILING
SHUTTERS, AND IN WINDOW PROTECTORS."
We take a series of round metallic rods and connect the same together at equal
distances apart and parallel to each other by means of a series of metallic wire coils.
These coils are made by twisting the wire (say by preference of iron or steel) several
times round a mandril and then continuing the wire across to another mandril set
at the desired distance apart, and round which the wire is again coiled in the same
or in the reverse direction to the previous coil, when it is once more brought back
and coiled round the first mandril and the same operation repeated until the desired
width of coil is obtained. These alternating coils are then interlaced similar to
hinge joints and held together by the rods being passed through them, and thus
when secured in position a metallic shutter or open grating is produced capable of
being wound upon a roller and otherwise mounted in the same manner as the
closed revolving or coiling lath shutters now in use.
And in order that this our said Invention may be the more readily understood
and carried into practical effect we have hereunto annexed two Sheets of Drawings s
illustrative of our improvements, Fig. 1 illustrating a front view of a shop window
fitted with our improved shutter, shewing the method of mounting the same, Fig. 2
being a side sectional view of Fig. 1 upon the line ab, and Fig. 3 a side sectional
view of Fig. 1 upon the line c-d. Fig. 4 represents a full sized view of a small
portion of the improved shutter, and also illustrates a convenient method of securing
the same to the roller upon which it is to be coiled or wound; Fig. 5 represents a
front, and Fig. 6 a side view of one of the metallic wire coils of which our improved
shutter is constructed.
In all the views A, A, are the metallic wire coils, having loops B, B, formed upon
them as hereinbefore described, and seen more clearly in Figs. 5 and 6. These metallic
coils are placed together, with their coils or loops B arranged to interlace alter-
nately similar to hinge joints (as seen more clearly in Fig. 4), and the rods C, C,
being then passed through the loops B, B, and secured in position, the coils become
connected together, and so a metallic shutter or open grating is produced, capable of
being wound upon a roller or otherwise mounted in the same manner as the closed
revolving or coiling lath shutters now in use.
In Fig. 4 we illustrate a side sectional view and in Fig. 4a a front view of
method of connecting our improved metallic shutter to a roller which consists of a
metallic tube or sheath D of sufficient substance, and having a longitudinal opening
or slit E extending throughout its whole length. This slit permits the eyes F to
slide in from either end, so that when.placed in position along such slit such eyes
serve as connections for the wire coils constituting the top extremity or edge of the
improved shutter, the bottom edge of the shutter being secured to the bottom
rail G.
The extremities of the rods C when passed through the coils may be riveted over
or slightly bent to retain them in position, and in order to effectually prevent the
shutter being drawn or forced away by main force from the window or other aperture
being protected, small oval plates of metal H are affixed at the extremities of some
of the rods, and are arranged to slide in a box groove I formed in the jamb of the
window or doorway to which the shutter is applied.
In Figs. 1, 2, and 3 we also illustrate a convenient method of actuating, coiling,.
and uncoiling our improved shutter, consisting of, a worm wheel D affixed on the
extremity of the roller J, in which gears a worm K, which is rotated by the winch
bandle L through the bevil wheels M as illustrated.

page_text: We would here observe that the wire coils of which our improved shutter is com-
posed may be in one continuous length from one side of the shutter to the other,
or several coils may be used in making up the length. The coils may be formed of
galvanised iron to resist the action of the atmosphere, and when an extra strong
shutter is required we make the same of steel wire and afterwards temper the coils.
It will be apparent that this improved shutter affords protection to a window
without concealing from view the contents of the shop or other apartment to which
the window appertains.
Having thus particularly described and ascertained the nature of this our said
Invention, together with the best methods with which we are acquainted for carrying
the same into practical effect, we wish it to be understood that we do not confine
ourselves to the precise details, relative proportions, or dimensions of the coils
hereinbefore described and illustrated on the accompanying Drawing, as the same
may be considerably varied without departing from the Invention, but what we
claim is,
The use and application of wire coils in the construction of a coiling or
revolving shutter, substantially as hereinbefore described, and illustrated on the
accompanying Drawing.
In witness whereof, I, the said John Greening, for and on behalf of the
said Noah Greening and myself, have hereunto set my hand and seal, this
Fifth day of June, in the year of our Lord One thousand eight hundred and
Beventy nine.
JOHN GREENING. (L.S.)
