PROVISIONAL SPECIFICATION.
Improvements in and relating to Blinds and Reflectors for Shop and
other Windows.
I, GEORGE ROBERTSON of 46 Dale Street, Kingston Glasgow North Britain
Tiusmith, do hereby declare the nature of this invention to be as follows:-
This invention relates chiefly to shop window screens or sun shades, which are
used in preference to blinds for the purpose of keeping the sun from shining upon
perishable articles when the same are exposed within the lower parts of the said
windows.
It has for its objects to render such screens capable of being, angled towards the
sun; easily put up or down; insusceptible to change by reason of heat or moisture,
and, all but indestructible.
In carrying out this invention I make a frame of angled iron of any suitable size
for covering the lower part of a window and furnish it with holes, pins, hooks or
other simple appliances for fitting it temporarily upon the outside of a window so
that it may be put up and taken down quickly after the manner of a shutter.
I furnish the said iron frame with a number of thin metal venetian shades fitted
vertically within it, each shade being pivotted, top and bottom to the frame so that
it may be turned to the right or left and placed at any required angle towards the
sun. I also unite each and all of the venetians to one or more guide bars, so that
by moving the said bar or bars the venetians are all simultaneously opened or closed
and they are fixed rigidly at any required angle by means of one or more thumb
screws or other simple appliances.
The frames are also designed for covering the upper parts of windows, whether
the latter are glaized or unglaized, and the venetians are sometimes placed
horizontally within the frames and the whole of such structures are designed for
application to other windows, than, as well as, those of sale shops.
The venetians are also made capable of serving the purposes of reflectors for
windows.

COMPLETE SPECIFICATION.
Improvements in and relating to Blinds and Reflectors for Shop and
other Windows.
I, GEORGE ROBERTSON of 46* Dale Street, Kingston Glasgow North Britain
Tinsmith 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 chiefly to shop window screens or sun shades, which are
used in preference to calico or such like blinds for the purpose of keeping the sun
from shining upon perishable articles when the same are exposed within the lower
parts of the said windows.
It has for its objects to render portions of such screens capable of being angled
towards the sun; easily put up or down; insusceptible to change by reason of heat
or moisture, and, all but indestructible.
In carrying out this invention I make a frame of angled iron, of any suitable size
for covering the lower part of a window and furnish it with holes, pins hooks or

page_text: other simple appliances for fitting it temporarily upon the outside of a window so
that it may be put up and taken down quickly and easily after the manner of a
shutter.
I furnish the said iron frame with a number of thin metal venetian shades fitted
vertically within it, each shade being pivotted, top and bottom, to the frame so that
it may be turned to the right or left and placed at any required angle towards
the sun.
I also unite each and all of the venetians to one or more guide bars, so that by
moving the said bar, or bars, the venetians are all simultaneously opened or closed
and they are fixed rigidly at any required angle by means of one or more thumb
screws or other simple appliances.
The frames are also designed for covering the upper parts of windows, whether
the latter are glaized or unglaized and the venetians are sometimes placed
horizontally within the frames, and the whole of such structures are designed for
application to other windows than, as well as, those of sale shops.
The venetians are also made capable of serving the purposes of reflectors for
windows.
My invention will be better understood by reference to the accompanying sheet
of drawings, in which :-
Fig. 1 is a view in elevation of my improved appliance closed;
Fig. 2 is a view in perspective of my improved appliance-open;
Fig. 3 is an end view in elevation of my improved appliance, closed;
Fig. 4 is an end view in elevation of my improved appliance closed;
Fig. 5. is a view in elevation of a part only of my improved appliance ;
Fig. 6 is a plan of my improved appliance, open.
Similar letters of reference indicate corresponding parts throughout the
drawings.
The metal frame A, A, B, B, Figs. 1 and 2 with stiffening bars C, C, C,
united rigidly to the frame, partly for the purpose of keeping the bars A, A, an
equal distance apart, is the supporting structure for the venetian shades D, D,
which are united to the said frame by being fixed upon the wire rods C and c';
some of the shades D are made to revolve upon rigidly fixed bars, marked C, and
others are fixed immoveably upon the rods c¹ which protrude at each extremity
beyond the said shade, the protruding ends serve as pivots for the shades, working
in sockets contained in or upon the bars A, A. The shades D are arranged
within the framework so that when they are closed they cover the whole day-
light breadth of the window.
In order to adapt these venetian shades for being angled oppositely, the end-
most one, (d) in the frame is made removeable so that it can be shifted from one
end of the frame to the other, and for this purpose a portion of the rod c³ which
unites the end shade d¹ to the frame is furnished with a handle or projecting
part and the said portion, if not the whole of the rod is made to slide like a bolt,
within eyes or sheaths upon the venetian shade so that it may be disengaged, together
with the shade, from the sockets in the bars A, A, and fitted at the opposite end of
'the frame.
Fig. 5 is an illustration of the end shade d' detached from the frame and furnished
with a sliding wire bolt and handle marked c³. For the purposes of my invention
a part only of the rod marked c* requires to be moveable, but if the whole rod is in
one piece and operated as a bolt the object which I have in view, namely, the
removal and replacement of the shade d¹ is efficiently attained. The pins Fig. 5
which protrude beyond the shade D are inserted in eyes, holes or sockets contained
in the locking bar a¹ and one or more of them, containing a screw thread serve the
purpose of binding the shade containing it rigidly to the bar a' when combined with
a winged nut a³.
One or more of the said locking bars, marked a¹ is or are connected with each
range of venetian shades by means of pins working in eyes or holes; the pins being
upon the shades and the eyes or holes in the bar a¹ or vice versa; also one or more

page_text: screws and winged nuts a², as above named, are fitted to the shades and bar a¹ for
the purpose of fixing the shades rigidly at any required angle.
In Figs. 1 and 2 I have shewn four tabs bi fixed upon the frame, containing key
hole slots for hanging this frame upon studs fixed upon or near the window; these
appliances may be greatly varied and are not essential parts of my invention as
this frame can be united to the window by catches, thumb bits or other simple
contrivances apart altogether from my venetian frame.
The frame A, A, B, B, can be constructed as shewn in the end elevation Fig. 3,
but the arrangement of its parts which are shewn in Fig. 4 is for all practical
purposes the best.
The venetians, D, are rendered capable of being used as reflectors by the
removal of the end one marked d¹ from one extremity of the frame to the other.
In one position the venetians give shade and coolness in bright and hot weather,
and when angled in an opposite direction they are capable of being used to reflect
light into the window.
The loose and removeable shade d' adapts the apparatus for being used upon
windows in opposite positions, whether the light comes from the right or left.
The apparatus as shewn in Figs. 1 and 2 can be fitted to a window in the
position shewn in the drawings or in a transverse attitude so that the shades appear
horizontal instead of vertical. They are designed to cover either the upper or
lower parts of windows or both and to be fitted in any attitude thereon.
These devices are intended chiefly to be made of metal for the purposes of
indestructibility and insusceptibility to change from damp or heat but parts of them
may if desired be made of other materials.
I am aware that prior to my invention domestic window screens have been made,
chiefly of wood, containing, within a framework, a number of rigidly fixed
venetian shades, generally arranged in two portions, one half of the frame
containing venetians angled one way and the other half of them being angled
oppositely thereto; also that shop window screens, variously made of wood or
wood and canvas combined, with metal pins and hooking on appliances; some of
the screens having immoveably fixed venetian shades and the shades of others
being pivotted and moveable similarly to those herein described and drawn; it
will therefore be understood that I do not claim broadly, as my invention the
construction of a window blind or screen composed largely of venetian shades.
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,
First. The combination of devices constituting my improved metal window blind,
all substantially as herein described and drawn, for the purposes specified.
Second. The combination of devices constituting my improved window reflector,
all substantially as herein described and drawn, for the purposes specified.
Third. In a framed venetian window blind such as herein defined the com-
bination therewith of a removeable and reversible shade d, and sliding bolt c³ c¹
all substantially as herein described and shewn, or any mere modification thereof
for the purposes specified.
Fourth. In a framed venetian window blind the combination therewith of a
locking bar a¹ and locking appliances d², a², all substantially as herein described
and drawn or any mere modification thereof, for the purposes specified.
Fifth. In a framed venetian window blind and reflector the combination there-
with of the removeable shade d¹ and locking appliances a¹ a² d² all substantially as
herein described and drawn or any mere modification thereof for the purposes
specified.
