PROVISIONAL SPECIFICATION.
An Improved Apparatus or Structure to be used in Conjunction
with Windows or the like as an Adjustable Sunshine Excluder.
I, EDWARD JOHNSON, of 131 Linthorpe Road, Middlesbrough-on-Tees, in the
County of York, Stationer and Tobacconist, do hereby declare the nature of this
invention to be as follows:-
My invention relates to an apparatus or structure to be used in conjunction with
windows or the like as a sunshine excluder in substitution for the usual street
awning for shop windows or the overhanging hoods in use for the windows of
houses.
These sunshine excluders as ordinarily used are so constructed that they cannot
be adjusted so as to afford a means of intercepting the rays of the sun at one time
without equally intercepting the daylight at all other times and require to be either
removed when not wanted or be allowed to remain in position as an obstruction to
the light of the window when such obstruction of light is not desirable.
The object of my invention is to construct sunshine excluders which are
adjustable in this respect so that they can be set to intercept the rays of the sun at
any time required, and can also be otherwise set so as only partially or not
perceptably to obstruct the light of the window when this would not be desirable.
In carrying out my invention I provide a series of leaves or louvre boards or
plates supported upon frames secured to the brickwork or wall of the building in
the form of a structure overhanging the window to be shaded, which leaves or
louvres overlap each other in succession in the downward order, so that a reliable,
perfect and weather tight roof is formed to overhang the window at a suitable
incline when the louvres are in the closed position they would occupy when set to
exclude the sunshine.
But in order to enable the sunshine to be excluded at one time and the daylight
to be admitted without obstruction at another time, I construct the said louvres
which form the roof and so fit them in their several positions that they can be
turned up separately or in combination edgewise to the direction at which light
which would be otherwise obstructed is now most freely admitted. To effect this
I avail myself of any suitable means or mechanism such as by furnishing each
louvre with a tilting bar projecting downwards a suitable length from a point of
connection as near in line as possible with the axis or centre line about which the
louvre is free to turn in the upward direction and by making each such tilting bar
rigid in the lifting direction a pull or thrust suitably applied thereto tilts the louvre
upwards from the closed position to the wide open or any intermediate position.
In order to simplify the tilting or adjusting mechanism for some cases I arrange
the several tilting bars all in line and connect them all to one connecting rod or
cord the thrust or pull of which acts upon all the said tilting bars alike and so the
several louvres are raised or lowered simultaneously, suitable mechanism being
provided in any convenient position for operating the rod or cord in the manner
required.

I, EDWARD JOHNSON, of 131, Linthorpe Road, Middlesbrough-on-Tees, in the
County of York, Stationer and Tobacconist, 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 :-
My invention relates to an apparatus or structure to be used in conjunction with
windows or the like as a sunshine excluder in substitution for the usual street
awning for shop windows or the overhanging hoods in use for the windows of
houses.
These sunshine excluders as ordinarily used are so constructed that they cannot
be adjusted so as to afford a means of intercepting the rays of the sun at one time
without equally intercepting the daylight at all other times, and require to be either
removed when not wanted or be allowed to remain in position as an obstruction to
the light of the window when such obstruction of light is not desirable.
The object of my invention is to construct sunshine excluders which are adjustable
in this respect so that they can be set to intercept the rays of the sun at any time
required, and can also be otherwise set so as only partially or not perceptably to
obstruct the light of the window, when this would not be desirable, while in the
case of rain they protect the shop front and pavement by effectually carrying the
water off.
And in order that my invention may be fully understood and readily carried into
effect I will now proceed to describe the same with reference to the accompanying
drawings hereto annexed, in which
Figure 1 illustrates in side elevation an adjustable sunshine excluder constructed
according to my invention fitted above a shop window with the shutters shown in
the closed position..
Figure 2 is a corresponding plan thereof with the shutters shown in the like
position, and
Figures 3 and 4 are detail views drawn to an enlarged scale.
In the drawings a represents a series of leaves or louvre boards or plates
preferably constructed of sheet steel and supported on angle bars b extending the
full length of the said plates to which they are attached, c are pivots bolted on
each end of the angle bars 6 working in bracket plates d; these bracket plates are
secured in front to the angle bar e and to the brickwork or wall of the building by
the angle barsel in the form of a structure overhanging the window to be shaded.
The leaves or louvres a overlap each other in succession in the downward order and
are preferably slightly curved along their free edges as shown more particularly in
Figure 3, so that a reliable, perfect and weather tight roof is formed to overhang
the window at a suitable incline when the louvres are in the closed position they
would occupy when set to exclude the sunshine.
But in order to enable the sunshine to be excluded at one time and the daylight
to be admitted without obstruction at another time, I construct the said louvres a,
which form the roof, and so fit them in their several positions that they can be
turned up separately or in combination edgewise to the direction at which light,
which would be otherwise obstructed, is now most freely admitted. To effect this
I avail myself of any suitable means or mechanism such as by furnishing each
louvre a with a tilting bar f projecting downwards a suitable length from a point
of connection as near in line as possible with the axis or centre line c about which
the louvre is free to turn in the upward direction, and by making each such tilting
bar frigid in the lifting direction a pull or thrust suitably applied thereto tilts the
•

page_text: louvre upwards from the closed position to the wide open or any intermediate
position as shown in dotted lines in Figure 3. In order to simplify the tilting or
adjusting mechanism for some cases I arrange the several tilting bars fall in line
and connect them to one connecting rod g or cord the thrust or pull of which acts
upon all the said tilting bars alike and so the several louvres are raised or lowered
simultaneously. Suitable mechanism for effecting this is shown in Figure 1, and
consists of the rod h coupled to the connecting rod g and the bell crank lever i, to
which is also connected the weighted lever; for operating the shutters as indicated
by the direction of the arrows. k is a Tiron support for the angle bars 6; 1 are
diagonal stays and l'cross stays for rigidly fixing the framework in position to
prevent sideward movement in case of wind pressure.
It must be understood that I do not restrict myself to the precise arrangement
of parts as herein before described and illustrated, as they may be varied without
departing from the essential features of my invention, as for instance, in the place
of the weighted bar j a spring or cord and weight may be substituted for actuating
the shutters.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
In an apparatus or structure to be used in conjunction with windows or the like
as a sunshine excluder, the use of a series of louvre boards actuated by tilting bars
so as to be adjustable to intercept the rays of the sun at any time required or
otherwise set so as only partially or not perceptably to obstruct the light of the
window when this would not be desirable, all arranged, combined and operating
together substantially in the manner as hereinbefore described and illustrated by
way of example in the accompanying drawings.
