IMPROVEMENTS IN AND RELATING TO REVOLVING SHUTTERS
Year: 1885

page_text: I, WILLIAM ROBERT LAKE, of the firm of Haseltine Lake & Co, Patent Agents
Southampton Buildings in the County of Middlesex do hereby declare the nature
of my invention for IMPROVEMENTS IN AND RELATING TO REVOLVING SHUTTERS
to be as follows:-
This invention relates to revolving corrugated metal shutters for protecting shop
windows, and for similar purposes.
The shutters of corrugated metal at present in use make a great noise when they
are operated.. This noise is occasioned by the space which it is requisite to leave
between the shutter and its guides. When the shutters are of large area there is a
certain amount of shake which increases the intensity of this noise.
In order to obviate these inconveniences I fix to the sides of the shutters steel
bands or strips of any suitable section so as not to impede the rolling, which bands
move in guides which are only large enough to permit a sliding movement of the
said bands therein. In this manner, the play being considerably reduced the noise
is prevented.
In carrying the said invention into practice I proceed as follows, that is to say,
to each side of the shutter which is rolled as usual upon a roller arranged in a
suitable place, is fixed a steel band which band slides in guides replacing the
ordinary guides generally formed of channel iron.
A metal band can be placed in front of each guide for protecting the frame of
the window from the friction of the corrugations of the metal.
In the case of a shutter of great width I fix to it one or more bands of steel or
other metal which give the shutter rigidity and prevent any shaking.

I, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,
Southampton Buildings in the County of Middlesex do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention relates to revolving corrugated-metal shutters for protecting shop
windows, and for similar purposes. -
The shutters of corrugated metal at present in use make a great noise when they
are operated, owing to the space which it is requisite to leave between the shutter
and its guides. Also when the shutters are of large area, there is a certain amount
of shake which increases the intensity of the noise.
In order to obviate these inconveniences, I fix to the sides of the shutters steel
bands or strips of any suitable section, so as not to impede the rolling, which bands
move in guides which are only large enough to permit a sliding movement of the
said bands therein. In this manner, the play being considerably reduced, the noise
is prevented.
:
My invention is illustrated in the accompanying drawing in which,
Figure 1 is an elevation of a shop front provided with a shutter constructed
according to this invention.
Figure 2 is a transverse section; and
Figure 3 is a horizontal section of the same.
Figure 4 represents one of the guides of the shutter drawn to an enlarged scale.
A is the shutter, the external appearance of which does not in any way differ as
will be seen from the drawing, from those heretofore constructed; and B is the
roller upon which the said shutter is adapted to be rolled:
Upon each of the edges a a¹ of the shutter A is fixed a steel band c, (Figure 4)
which bands slide in guides D, D, replacing the ordinary guides generally formed
of channel iron.
A metal band E can be placed in front of each guide for protecting the frame of
the window or the like from contact with the corrugations of the metal.
In the case of a shutter of great width, I fix to it one or more bands F of steel
or other metal (Figure 1) which bands give the shutter rigidity and prevent any
shaking.

page_text: Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed as communicated to
me by my foreign correspondent, I declare that what I claim is :-
First. In a corrugated metal shutter, the employment of bands of steel or other
metal fixed to the edges of the said shutter and running in suitable guides,
substantially as, and for the purpose specified.
Second. The application of steel or other metal bands F to the body of the
shutter for the purpose specified.
Third. A revolving shutter constructed substantially as herein before described
and shewn in the accompanying drawing.
