IMPROVEMENT IN CORRUGATED METAL ROLLING SHUTTERS
Year: 1884

page_text: I, SAMUEL PEARCE WILDING, of the firm of Fell and Wilding, of 23 Rood Lane,
Fenchurch Street, in the City of London, Patent Agents, do hereby declare the
nature of the said invention for "IMPROVEMENT IN CORRUGATED METAL ROLLING
SHUTTERS," to be as follows:-
My invention relates to corrugated metal rolling shutters, and it is designed,
firstly, to strengthen and protect those parts of the shutter which are most liable to
wear; secondly, to deaden the noise usually consequent upon the operation of
such shutters; thirdly, to permit of easy repair of slight damage.
The construction of my device is as follows:-
Upon the crowns of the corrugations of the shutter, and accurately fitting
thereto, are shields of metal, which are rivetted through the shutter to pads on its
opposite side of suitable form and material to allow of the movement of the shutter.
These pads may or not be faced. I prefer to place the shields on both edges
of the shutter and on every alternate corrugation. My invention, however, will be
employed if the shields are placed on every corrugation or on corrugations farther
apart, and on both sides of the shutter. I do not confine myself to any particular
part of the shutter, but may place the shields wherever extra strength is required.
When the shutter is being coiled or uncoiled, the corrugations are prevented by
my device from catching in one another, and the noise thereby occasioned is
obviated, and at the same time the shields protect the shutter wherever they are
placed and prevent it wearing out. I propose also to use the shields for repairing
and strengthening old shutters, for rivetting on patches, or for covering such small
holes as time or accident may have occasioned.

page_text: I, SAMUEL PEARCE WILDING, of the firm of Fell and Wilding, of 23 Rood Lane,
Fenchurch Street, in the City of London, Patent Agents, do hereby declare the
nature of the said Invention for an "IMPROVEMENT IN CORRUGATED METAL
ROLLING SHUTTERS" and in what manner the same is to be performed to be
particularly described and ascertained in and by the following Statement:—
My Invention relates to Corrugated Metal Rolling Shutters and it is designed,
firstly, to strengthen and protect those parts of the shutter which are most liable to
wear; Secondly, to deaden the noise usually consequent upon the operation of such
shutters; Thirdly to permit of easy repair of slight damage.
The Construction of my device is as follows:-
Upon the crowns of the Corrugations of the shutter and accurately fitting
thereto, are shields of metal, which are rivetted through the shutter to pads on
its opposite side of suitable form and material to allow of the movement of the
shutter. These pads may or not be faced. I prefer to place the shields on

myself to any particular part of the shutter, but may place the Shields wherever
extra strength is required.
When the shutter is being coiled or uncoiled, the corrugations are prevented by
my device from catching in one another, and the noise thereby occasioned is
obviated, and at the same time the shields protect the shutter wherever they are
placed and prevent it wearing out. I propose also to use the shields for repairing
and strengthening old shutters, for rivetting on patchis, or for covering such small
.holes as time or accident may have occasioned.
In order that my Invention may be the better understood, I now proceed to
describe the same with reference to the drawings hereunto annexed, reference being
had to the letters and figures marked thereon.
Like letters refer to like parts throughout the drawings.
Figs. 1 and 2 are edge views of my shutter.
Fig 3 is a front view.
:
Similar letters refer to similar parts in each view; a. a are metal shields formed
to fit accurately the crown of the Corrugation and rivetted through the shutter to
pads or washers b. b on the opposite side, of suitable form and material to allow of
the movement of the shutter; the object being simply to prevent, when the shutter
is being coiled or uncoiled, the Corrugations catching in each other. The noise
occasioned by this catching or slipping of the Corrugations will thus be prevented,
and at the same time the metal shields will protect the shutter wherever they are
placed and prevent it from wearing out.
The metal shields are preferably of the form shown on the drawing and about
one inch in length, but I do not confine myself to the exact form or dimension.
.I prefer to place these metal shields on both edges of the shutter and on every
alternate corrugation. My invention however will be employed if the metal
shields are placed on every corrugation and on both sides of the shutter, or on
corrugations farther apart.
I propose also to use the shields for repairing and strengthening old shutters, for
rivetting on patches or for covering up such small holes as time or accident may
have occasioned.

page_text: I do not confine myself to any particular part of the shutter for affixing my
shields but intend placing them on any part where extra strength may be
required.
I am aware that attempts have been made to prevent noise by the application
to the edges of the shutter of leather strips or other soft material and I am aware
that Letters Patent were granted for such a device on April 8 1873 to Alexander
Clark. My Invention however is essentially different from this inasmuch as
I propose to prevent the noise in operating and at the same time strengthen the
shutter by a device entirely different.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1 A corrugated metal rolling shutter, having its edges and those portions of its
face or faces contiguous thereto protected and strengthened by means of superposed
metal shields fitted to the crowns of individual corrugations and individually
attached, substantially as shewn and described.
2nd A corrugated metal rolling shutter having washers or pads fixed in the
concavities of its corrugations but not projecting beyond the crowns of its convex
surfaces, substantially as shewn and described..
3rd The combination with a corrugated metal rolling shutter of metal shields
and pads, substantially as described.
